Humanity’s farthest and longest-lived spacecraft, Voyager 1 and 2, achieve 40 years of operation and exploration this August and September. Despite their vast distance, they continue to communicate with NASA daily, still probing the final frontier.

Their story has not only impacted generations of current and future scientists and engineers, but also Earth’s culture, including film, art and music. Each spacecraft carries a Golden Record of Earth sounds, pictures and messages. Since the spacecraft could last billions of years, these circular time capsules could one day be the only traces of human civilization.

Thomas Zurbuchen is associate administrator for NASA’s Science Mission Directorate (SMD) at NASA Headquarters. He said:

I believe that few missions can ever match the achievements of the Voyager spacecraft during their four decades of exploration. They have educated us to the unknown wonders of the universe and truly inspired humanity to continue to explore our solar system and beyond.

The Voyagers have set numerous records in their unparalleled journeys. In 2012, Voyager 1, which launched on September 5, 1977, became the only spacecraft to have entered interstellar space. Voyager 2, launched on August 20, 1977, is the only spacecraft to have flown by all four outer planets – Jupiter, Saturn, Uranus and Neptune. Their numerous planetary encounters include discovering the first active volcanoes beyond Earth, on Jupiter’s moon Io; hints of a subsurface ocean on Jupiter’s moon Europa; the most Earth-like atmosphere in the solar system, on Saturn’s moon Titan; the jumbled-up, icy moon Miranda at Uranus; and icy-cold geysers on Neptune’s moon Triton.

Though the spacecraft have left the planets far behind – and neither will come remotely close to another star for 40,000 years – the two probes still send back observations about conditions where our sun’s influence diminishes and interstellar space begins.

On September 6, 2103, NASA released this artist’s concept showing the general locations of NASA’s two Voyager spacecraft. NASA wrote, “Voyager 1 (top) has sailed beyond our solar bubble into interstellar space, the space between stars. Its environment still feels the solar influence. Voyager 2 (bottom) is still exploring the outer layer of the solar bubble.” Image NASA/JPL-Caltech

Voyager 1, now almost 13 billion miles from Earth, travels through interstellar space northward out of the plane of the planets. The probe has informed researchers that cosmic rays, atomic nuclei accelerated to nearly the speed of light, are as much as four times more abundant in interstellar space than in the vicinity of Earth. This means the heliosphere, the bubble-like volume containing our solar system’s planets and solar wind, effectively acts as a radiation shield for the planets. Voyager 1 also hinted that the magnetic field of the local interstellar medium is wrapped around the heliosphere.

Voyager 2, now almost 11 billion miles from Earth, travels south and is expected to enter interstellar space in the next few years. The different locations of the two Voyagers allow scientists to compare right now two regions of space where the heliosphere interacts with the surrounding interstellar medium using instruments that measure charged particles, magnetic fields, low-frequency radio waves and solar wind plasma. Once Voyager 2 crosses into the interstellar medium, they will also be able to sample the medium from two different locations simultaneously.

Ed Stone is Voyager project scientist based at Caltech in Pasadena, California. Stone said:

None of us knew, when we launched 40 years ago, that anything would still be working, and continuing on this pioneering journey. The most exciting thing they find in the next five years is likely to be something that we didn’t know was out there to be discovered.

The twin Voyagers have been cosmic overachievers, thanks to the foresight of mission designers. By preparing for the radiation environment at Jupiter, the harshest of all planets in our solar system, the spacecraft were well equipped for their subsequent journeys. Both Voyagers are equipped with long-lasting power supplies, as well as redundant systems that allow the spacecraft to switch to backup systems autonomously when necessary. Each Voyager carries three radioisotope thermoelectric generators, devices that use the heat energy generated from the decay of plutonium-238 – only half of it will be gone after 88 years.

Space is almost empty, so the Voyagers are not at a significant level of risk of bombardment by large objects. However, Voyager 1’s interstellar space environment is not a complete void. It’s filled with clouds of dilute material remaining from stars that exploded as supernovae millions of years ago. This material doesn’t pose a danger to the spacecraft, but is a key part of the environment that the Voyager mission is helping scientists study and characterize.

Because the Voyagers’ power decreases by four watts per year, engineers are learning how to operate the spacecraft under ever-tighter power constraints. And to maximize the Voyagers’ lifespans, they also have to consult documents written decade’s earlier describing commands and software, in addition to the expertise of former Voyager engineers.

Suzanne Dodd is Voyager project manager based at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California. She said:

The technology is many generations old, and it takes someone with 1970s design experience to understand how the spacecraft operate and what updates can be made to permit them to continue operating today and into the future.

Team members estimate they will have to turn off the last science instrument by 2030. However, even after the spacecraft go silent, they’ll continue on their trajectories at their present speed of more than 30,000 mph (48,280 kilometers per hour), completing an orbit within the Milky Way every 225 million years.

America’s Previous Coast-To-Coast Eclipse Almost Proved Einstein Right (Synopsis) [Starts With A Bang]

“Astronomers are greatly disappointed when, having traveled halfway around the world to see an eclipse, clouds prevent a sight of it; and yet a sense of relief accompanies the disappointment.” –Simon Newcomb

On August 21st, a total solar eclipse will travel coast-to-coast across the United States, bringing darkness during the day to portions of 14 separate states. The last time such an event occurred was 99 years ago, back in 1918. Back then, Einstein’s General Relativity still had not been proven, and this eclipse not only provided that opportunity, but held an opportunity for America to rise to scientific prominence in the world.

The path of the total solar eclipse of 1918. Image credit: Eclipse Predictions by Fred Espenak, NASA’s GSFC.

The U.S. Naval Observatory sent a team of physicists to Baker City, Oregon, to attempt to make the critical observations. If Einstein was right, starlight would deflect during the day the closer a star’s position was to the Sun. If nature was kind to those fastidious observers, the data could indicate which theory, Newton’s or Einstein’s, was correct. But at the critical moment, the Americans were defeated by nature itself, in the form of clouds.

Still, the last Great American Eclipse almost proved Einstein right. As the 2017 eclipse approaches, take a look back at a little-known slice of American history!

The cruel sham that is “right-to-try” is one big step closer to being federal law [Respectful Insolence]

The moment I have feared ever since Republicans took control of all three branches of Congress last fall has come one step closer to reality. Actually, it’s merely one of many. occurrences that I have feared, given that Donald Trump has been our President for over six months. Although you won’t find much in the news about it, yesterday the Senate easily passed a federal version of so-called “right-to-try.” Senator Ron Johnson, who threatened to hold up Senate business unless a right-to-try rider was approved for the bill funding the FDA for the next seven years, was ecstatic:

As was Christina Sandefur of the Goldwater Institute, the libertarian think tank who concocted the idea of using right-to-try as a means of enlisting terminally ill patients as sympathetic pawns in its never-ending war on government regulation in general and the ability of the FDA to protect patients from unsafe and ineffective drugs:

Basically, all that has to happen in September, when Congress reconvenes, is for the House to pass this law. One the one hand, I’m relieved that it’s just the standalone law that passed and that right-to-try wasn’t attached to the bill that allows the FDA to collect user fees from companies seeking FDA approval for their drugs and devices, but that doesn’t make the bill any less dangerous to patients. I will also grant that, as you will see, the bill as passed is not as bad as the original version of the bill (S. 204: Trickett Wendler Right to Try Act of 2017), but it still has the potential to do a lot of mischief, endanger a lot of patients, and empower a lot of scammers. To understand why, though, you need to understand what right-to-try is.

Right-to-try: A cruel sham that politicians can’t oppose

I’ve written many times before over the last three years about how “right-to-try” laws have swept the states. When last I wrote about right-to-try, 37 states had passed such laws over the course of a mere three years, and I observed at the time that it wouldn’t surprise me in the least if most or all of the remaining states were to pass such laws within the next year or two. Basically, the idea behind these laws is that the FDA is killing patients (I’m only exaggerating slightly) through its slow drug approval, overcaution, and bureaucratic inertia, or at least letting them die because life-saving drugs are being held up. So the idea, hatched by the Goldwater Institute was that terminally ill patients should have the “right-to-try” experimental drugs not yet approved by the FDA because they have nothing more to lose. Of course, it’s not true that they have nothing more to lose, but I’ll discuss that more later. Basically, right-to-try laws purport to allow the terminally ill “one last shot” by letting them access experimental therapeutics outside of FDA-sanctioned clinical trials. However, these laws operate under a number of false assumptions, not the least of which is the caricature of the FDA as being slow, inefficient, and unwilling to bend, as you will see. They also strip away a number of protections for patients, as you will also see.

Who could argue with that, right? That is, of course, the issue. These laws sound very pro-patient, but they are in reality a Trojan horse designed to weaken the regulatory power of the FDA. They are a cruel sham, an illusion. As I’ve said from the beginning, Dallas Buyers Club might have been a good movie (I actually was disappointed in it when I actually saw it), but it’s a horrible basis for public policy on drug regulation. Indeed, right-to-try is a triumph of marketing that allowed anyone who perceived how it degrades patient protections, sells false hope, and harms the clinical trial process to no one’s benefit as heartless monsters who have no empathy for dying patients and value science over people. Indeed, this is exactly the sort of rhetoric one sees aimed at opponents on Twitter:

And:

Basically, if you speak out for patients and against right-to-try, you will be painted as cold and indifferent to the suffering of terminally ill patients. For me, nothing could be further from the truth. Either that, or you’ll be painted as being in the pocket of big pharma. All of this propaganda had a very chilling effect on criticism. I realize it’s an unscientific sample, but I know of no one involved in, for instance, cancer clinical trials at academic medical centers who supports right-to-try. Yet, whenever right-to-try bills were introduced in various states, the silence from medical professional organizations, universities, cancer centers, and the like was deafening. When right-to-try came to Michigan, almost no one testified against it, and the Goldwater Institute was free fly in a parade of families of patients with terminal illnesses who were convinced that right-to-try would give their loved ones a shot at life. The same sort of thing happened in the Senate over S.204:

But more liberal lawmakers faced significant lobbying, featuring heartbreaking stories of young children or newlyweds facing shortened lives. Meanwhile, the most powerful opposition, the drug industry and doctors’ groups, kept their disagreement very low-profile. Their soft voices gave lawmakers little political protection for a “no” vote.

“There’s no doubt about it — there are a lot of patients out there that think this is the answer to their prayers. … They certainly believed that, and they pushed their members of Congress to support a bill that in many cases the members of Congress thought was not a good idea,” said Zuckerman.

PhRMA’s low-profile on right-to-try hurt detractors from the outset. The industry group never took a formal position on the state right-to-try laws or earlier federal proposals. But it consistently reiterated its concerns about any approach to experimental medicines that sought to bypass the FDA and the clinical trial process. Of the major drug makers, only Merck formally came out against the earlier Johnson bill.

“It’s huge,” NYU’s Bateman-House said of PhRMA’s reluctance to take a stronger public stance. “When I speak with legislators, they say, ‘Well if it’s that bad, why isn’t pharma speaking against it?’”

The same could be said of the American Society of Clinical Oncology (ASCO), which spent the last three years taking no position on right-to-try until three months ago, by which time it was too little, too late. It’s not for nothing that I once remarked sardonically that opposing right-to-try is perceived the same way as opposing mom, apple pie, and the American flag—or worse, wanting to kill mom, defile apple pie, and shred the American flag. Again, I exaggerate, but not by much.

By drafting terminally ill patients into its war with the FDA, the Goldwater Institute could basically falsely equate criticism of right-to-try with attacks on dying patients. It was a cynical and very likely intentional strategy, and it worked brilliantly to silence groups that could have been the most effective opposition to right-to-try until it was too late. But what’s wrong with right-to-try anyway? To answer that, I’ll briefly reiterate the problems with state right-to-try laws and then to discuss the problem with the federal right-to-try bill as passed.

The problem with state right-to-try laws

All the state right-to-try laws hew pretty tightly to an approved model legislation template originally developed by the Goldwater Institute. Given that, all state right-to-try laws share several major features. The first was the requirement that the disease the patient has be terminal, usually defined as having a life expectancy of less than six months, although the model legislation is more vague, requiring an “advanced disease,” defined as “progressive disease or medical or surgical condition that entails significant functional impairment, that is not considered by a treating physician to be reversible even with administration of current federal drug administration approved and available treatments, and that, without life-sustaining procedures, will soon result in death.” Various states define this condition in somewhat different ways, but you get the idea. In fact, the federal legislation uses a definition more like the latter than the former.

One of the most problematic passages, if not the most problematic passage, in all right-to-try laws, including the federal one passed by the Senate, is the definition of “investigational drug, biologic product, or device”:

“Investigational drug, biological product, or device” means a drug, biological product, or device that has successfully completed phase 1 of a clinical trial but has not yet been approved for general use by the United States food and drug administration and remains under investigation in a United States food and drug administration-approved clinical trial.

Every right-to-try bill or law I’ve read uses minor variations of the above definition. Anyone who knows anything about drug development shudders when reading passages like that. The reason is that having completed a phase 1 trial is a dangerously low bar to clear to allow more widespread use of a drug. Basically phase 1 trials are small trials, usually consisting of less than 30 subjects, that look for major toxicities and adverse events. That is not enough to determine safety, nor is it intended to. Phase I trials are designed primarily to identify major side effects and to use a process known as dose escalation to determine what is commonly referred to as the “maximum tolerated dose.” It is utterly impossible for such a small clinical trial to determine the safety of a drug. Phase II and Phase III trials are needed to confirm safety. Think of phase I trials as a screening test looking for the most obvious toxicities, with phase II and III studies confirming them. Indeed, even phase III trials can’t always adequately demonstrate that a drug is safe; it’s not uncommon for less common adverse effects not to show up until post-marketing surveillance, when much larger numbers of patients receive the drug. Moreover, only 5% of all cancer drugs that enter clinical testing are ultimately approved for patient use. Among drugs tested in phase II trials, only 30% go on to phase 3. I like to point to the cautionary example of amonifide for treating breast cancer. The drug made it through phase I trials, but serious life-threatening hematologic toxicity emerged during phase II trials.

Another problem with right-to-try laws is that they are extremely inequitable. Basically, right-to-try laws limit who can access them by wealth. The reason is that all of them have a provision that says that health insurance companies do not have to pay for right-to-try treatments and most such laws allow drug companies to charge whatever they see fit for the experimental drug. Insurance companies can pay if they so desire, but what’s the likelihood of an insurance company paying for an experimental treatment?It goes beyond that, though. If a patient uses a right-to-try drug and suffers complications, these laws basically state that the insurance company doesn’t have to pay for care resulting from that complication, and all such laws state that patients undergoing right-to-try therapies lose their coverage for hospice while undergoing right-to-try treatment. Thus, a terminally ill patient could easily go bankrupt before he died paying for drugs accessed through right-to-try laws, and many couldn’t access experimental therapeutics through such laws in any event because they simply don’t have the money or the fundraising wherewithal to do so.

Right-to-try laws also limit what patients can do in the event of malpractice or negligence. All of them immunize physicians advising or administering right-to-try medications against malpractice suits or actions against their medical license by the state medical board for doing so. All of them contain provisions broadly immunizing companies providing experimental therapeutics under right-to-try from liability. All of them contain provisions stating that state employees can’t interfere with a patient seeking right-to-try, which could be interpreted to mean that a doctor at an academic medical center at a state university couldn’t counsel a patient not to seek right-to-try without running afoul of the law. As Jann notes, even if state authorities believe, for example, that an elderly person is being exploited for financial gain by a physician, presumably this provision would prohibit their acting.

Right-to-try laws are patient-hostile in other ways, too, as Jann Bellamy and I have described many times. The most egregious example of which is how they strip patient protections away from patients who access them. One way to see this is by comparing what happens when a patient accesses an experimental therapeutic under the FDA expanded access program to what happens when another patient accesses one under a right-to-try law. Under FDA expanded access, patients retain full protections under federal and state laws. They can sue for malpractice if there is any, and their care is still monitored by an institutional review board (IRB), with any adverse events recorded and considered by the FDA. Moreover, the FDA approves nearly all such requests (99%). In contrast, under right-to-try, there is no IRB oversight. It’s all between the company and the patient.

Finally, I not infrequently call state right-to-try laws placebo legislation because such laws basically does nothing while making everyone feel better. That’s because the federal government, not the states, controls drug approval. Basically, the state can say that patients have a “right-to-try,” but only the federal government can actually guarantee such a “right.” It’s actually fortunate that state-level right-to-try laws are placebo laws, because if they actually did what’s in their text they would be profoundly harmful to patients.

The problem with the version of “right-to-try” passed by the Senate

In marked contrast to state-level laws, any federal right-to-try bill that becomes law would not be placebo legislation. It would be harmful, and the Trickett Wendler Right to Try Act of 2017, although amended to be less harmful than the original version, is still a danger to patients. I described in detail what was in the original version of this bill in previous posts; so I won’t dwell too much on it. The key points of the original bill were:

  • No interference by the federal government with state right-to-try laws.
  • No liability for either drug companies providing right-to-try or doctors recommending right-to-try
  • No use of outcomes from patients accessing right-to-try in FDA consideration of drug approval.

So let’s look at S.204 as passed by the Senate. It’s still bad, but not as bad because there are amendments that mitigate some of the worst aspects of the original. Unfortunately, it still uses an overly broad definition of who can access right-to-try. Basically, anyone with a serious illness as defined by the FDA is eligible. The bill also retains the dangerously nonsensical provision that any drug that’s passed phase I trials and is still in active development can be accessed through right-to-try.

One thing the new “right-to-try” does is to change the provision in the original version that forbade the FDA from considering outcomes observed in patients accessing a drug by right-to-try in its deliberations over whether to approve the drug or not:

(1) IN GENERAL.—Notwithstanding any other provision of this Act, the Public Health Service Act, or any other provision of Federal law, the Secretary may not use a clinical outcome associated with the use of an eligible investigational drug pursuant to this section to delay or adversely affect the review or approval of such drug under section 505 of this Act or section 351 of the Public Health Service Act unless—

(A) the Secretary makes a determination, in accordance with paragraph (2), that use of such clinical outcome is critical to determining the safety of the eligible investigational drug; or

(B) the sponsor requests use of such outcomes.

The “Secretary” above is the Secretary of Health and Human Services, although the HHS Secretary can delegate the decision to the FDA Commissioner.

The new right-to-try also requires the FDA to post information regarding right-to-try on its website:

(1) IN GENERAL.—The manufacturer or sponsor of an eligible investigational drug shall submit to the Secretary an annual summary of any use of such drug under this section. The summary shall include the number of doses supplied, the number of patients treated, the uses for which the drug was made available, and any known serious adverse events. The Secretary shall specify by regulation the dead line of submission of such annual summary and may amend section 312.33 of title 21, Code of Federal Regulations (or any successor regulations) to require the submission of such annual summary in conjunction with the annual report for an applicable investigational new drug application for such drug.

(2) POSTING OF INFORMATION.—The Secretary shall post an annual summary report of the use of this section on the internet website of the Food and Drug Administration, including the number of drugs for which clinical outcomes associated with the use of an eligible investigational drug pursuant to this section was—

(A) used in accordance with subsection (c)(1)(A);
(B) used accordance with subsection (c)(1)(B); and
(C) not used in the review of an application under section 505 of this Act or section 351 of the Public Health Service Act.

As you can see, this is better, but still problematic. Basically, the FDA Commissioner can decide on an individual basis whether or not to use right-to-try outcomes in considering the approval of a drug. I can see considerable potential for favoritism and abuse in this provision, in which favored companies can do what they like and not have to worry about whether right-to-try outcomes will count against them and less favored companies will have to worry. it is, however, good that at least there will be some transparency, as some information will have to be made publicly available.

The modified bill also softens the protections against lawsuits against manufacturers and doctors recommending right-to-try with an exception to immunity if “the relevant conduct constitutes reckless or willful misconduct, gross negligence, or an intentional tort under any applicable State law.” Now, I’m not a lawyer, but here’s one huge problem with this that I see. State right-to-try laws in general completely immunize manufacturers providing experimental therapeutics under the law and doctors recommending such therapeutics from any legal liability; so in those states there would be nothing patients could sue for, even in the case of “reckless or willful misconduct, gross negligence, or an intentional tort.” If there are any lawyers out there, feel free to correct me if I’m wrong, but it appears that only in states without right-to-try would this provision mean anything.

What now?

Now that S.204 has been passed by the Senate, it moves on to the House, where, unfortunately, it is highly likely to pass. Given the anti-regulatory mood of the current Congress, coupled with the successful branding of right-to-try opponents as either in the pocket of big pharma or indifferent to the suffering of the terminally ill, it will be very, very difficult to stop this bill. That doesn’t mean that we shouldn’t continue to try, but we should have no illusions. We are likely to see what happens if right-to-try becomes the law of the land at the federal level. While it’s true that this version is not quite as patient- and science-hostile as the original version, it is, unfortunately, plenty bad, man.

It’s also not as though we haven’t had a chance to see if right-to-try provides any of the benefits claimed for it. Unfortunately, thus far, right-to-try has been a miserable failure, despite three years for it to have proven its worth. I know. I’ve looked for “success stories,” and the Goldwater Institute has been unable to provide them.

Sandefur has, however, been able to provide the same old talking points about the FDA Expanded Access Program and about how slow the FDA allegedly is approving drugs. It actually turns out that the FDA is faster than its European counterparts approving drugs and that the expanded access program is nowhere near as onerous as ideologues like Sandefur like to paint it. Indeed, there is a nice FAQ maintained by the NYU Working Group on Compassionate Use and Pre-Approval Access that answers pretty much every talking point, and I’ve discussed these same talking points before. It’s basically a lot of misinformation promoted by ideologues.

Nor is this “success story” persuasive if you look into it more:

Now, as to Right to Try: when real-life examples of its early success are reported, Klugman’s response is to deny that they are true—and this is frankly bizarre. Dr. Delpassand has testified to Congress that within a year of his state’s enacting Right to Try, he successfully treated 78 terminally ill cancer patients using LU-177, a drug that had successfully completed its three phases of the FDA-approved clinical trials and has been available in European countries for years, but has still not received final FDA approval for sale. I should know, since I’m his lawyer: Dr. Delpassand had administered a successful FDA-approved clinical trial for LU-177 therapy for five years, but was then told by the FDA that he could not add more patients to the trial. Right to Try enabled him to continue administering LU-177 to patients suffering from neuroendocrine cancer after the FDA blocked the trial’s expansion. His patients were exceedingly grateful. One said that without Right to Try, he “would have had to go on disability to make trips to Switzerland.” Another said he “would have traveled to Switzerland for this same treatment and follow-up appointments every three months,” but thanks to Right to Try and Dr. Delplassand, he was able to stay in the United States and spend the time with his wife and kids. “This law,” he told me, “has been a life saver!”

I discussed the example of Dr. Delpassand and his company Excel Diagnostics in detail before, as well as how Dr. Delpassand is a cheerleader for the Goldwater Institute who’s done promotional videos for right-to-try before. Basically, the treatment being promoted by Dr. Delpassand for neuroendocrine tumors has promise. It even was found in a phase III trial published earlier this year to produce a significant increase in progression-free survival for midgut neuroendocrine tumors. However, as I described in depth, there was something fishy about the story. He claimed to be administering his radionuclide treatment under Texas’s right-to-try law, but he was charging patients and the Texas right-to-try law, as I was so pointedly reminded when I discussed the issue, doesn’t allow manufacturers to charge for their experimental therapeutic.

Basically, reading between the lines in Sandefur’s article, I now think I know what happened, and it’s not exactly what is being claimed. What it sounds like to me from Sandefur’s carefully worded account, plus what I’ve looked up before, is that, after having reached his accrual target for his clinical trial, Dr. Delpassand wanted to add additional patients to it even though the trial was closed. The FDA balked at this request—and understandably so. The reason was almost certainly that adding patients to a clinical trial after it’s closed is, in essence, changing the design of the trial post-hoc. It would also have increased the time necessary to analyze the trial. So Dr. Delpassant appears to have used the right-to-try law to get what he wanted. As I documented before from a patient webpage, he also appeared to be charging patients close to $40,000 for the treatment, although it is unclear whether he charged for his radionuclide or not or whether he followed the Stanislaw Burzynski method and charged large sums of money for everything else but the drug and thus made money that way.

I mention the Houston Cancer Quack Stanislaw Burzynski on purpose, because, before Dr. Delpassand, he was the only “investigator” I had heard of who had actually used right-to-try to bypass the FDA and continue to administer his antineoplastons. I fear his is the business model that right-to-try will enable, complete with exploitation of patients on a greater-than-Burzynski scale.

Meanwhile:

“This bill is inherently deceptive,” Alison Bateman-House, a medical ethicist at New York University who led the charge against Johnson’s bills, wrote in an email. “What [patients] have a right to (and did long before this bill) is to ask drug companies for permission to use their experimental drugs outside of clinical trials. If the drug company says no, both before and after this legislation, that’s the final word: neither the FDA nor the courts have to power to make companies provide access to their experimental drugs-in-development.”

That’s why it is not cold, cruel, or indifferent to oppose right-to-try. It is not anti-patient. Quite the opposite, in fact. It is as pro-patient as you can get to try to stop this cruel sham.

The moment I have feared ever since Republicans took control of all three branches of Congress last fall has come one step closer to reality. Actually, it’s merely one of many. occurrences that I have feared, given that Donald Trump has been our President for over six months. Although you won’t find much in the news about it, yesterday the Senate easily passed a federal version of so-called “right-to-try.” Senator Ron Johnson, who threatened to hold up Senate business unless a right-to-try rider was approved for the bill funding the FDA for the next seven years, was ecstatic:

As was Christina Sandefur of the Goldwater Institute, the libertarian think tank who concocted the idea of using right-to-try as a means of enlisting terminally ill patients as sympathetic pawns in its never-ending war on government regulation in general and the ability of the FDA to protect patients from unsafe and ineffective drugs:

Basically, all that has to happen in September, when Congress reconvenes, is for the House to pass this law. One the one hand, I’m relieved that it’s just the standalone law that passed and that right-to-try wasn’t attached to the bill that allows the FDA to collect user fees from companies seeking FDA approval for their drugs and devices, but that doesn’t make the bill any less dangerous to patients. I will also grant that, as you will see, the bill as passed is not as bad as the original version of the bill (S. 204: Trickett Wendler Right to Try Act of 2017), but it still has the potential to do a lot of mischief, endanger a lot of patients, and empower a lot of scammers. To understand why, though, you need to understand what right-to-try is.

Right-to-try: A cruel sham that politicians can’t oppose

I’ve written many times before over the last three years about how “right-to-try” laws have swept the states. When last I wrote about right-to-try, 37 states had passed such laws over the course of a mere three years, and I observed at the time that it wouldn’t surprise me in the least if most or all of the remaining states were to pass such laws within the next year or two. Basically, the idea behind these laws is that the FDA is killing patients (I’m only exaggerating slightly) through its slow drug approval, overcaution, and bureaucratic inertia, or at least letting them die because life-saving drugs are being held up. So the idea, hatched by the Goldwater Institute was that terminally ill patients should have the “right-to-try” experimental drugs not yet approved by the FDA because they have nothing more to lose. Of course, it’s not true that they have nothing more to lose, but I’ll discuss that more later. Basically, right-to-try laws purport to allow the terminally ill “one last shot” by letting them access experimental therapeutics outside of FDA-sanctioned clinical trials. However, these laws operate under a number of false assumptions, not the least of which is the caricature of the FDA as being slow, inefficient, and unwilling to bend, as you will see. They also strip away a number of protections for patients, as you will also see.

Who could argue with that, right? That is, of course, the issue. These laws sound very pro-patient, but they are in reality a Trojan horse designed to weaken the regulatory power of the FDA. They are a cruel sham, an illusion. As I’ve said from the beginning, Dallas Buyers Club might have been a good movie (I actually was disappointed in it when I actually saw it), but it’s a horrible basis for public policy on drug regulation. Indeed, right-to-try is a triumph of marketing that allowed anyone who perceived how it degrades patient protections, sells false hope, and harms the clinical trial process to no one’s benefit as heartless monsters who have no empathy for dying patients and value science over people. Indeed, this is exactly the sort of rhetoric one sees aimed at opponents on Twitter:

And:

Basically, if you speak out for patients and against right-to-try, you will be painted as cold and indifferent to the suffering of terminally ill patients. For me, nothing could be further from the truth. Either that, or you’ll be painted as being in the pocket of big pharma. All of this propaganda had a very chilling effect on criticism. I realize it’s an unscientific sample, but I know of no one involved in, for instance, cancer clinical trials at academic medical centers who supports right-to-try. Yet, whenever right-to-try bills were introduced in various states, the silence from medical professional organizations, universities, cancer centers, and the like was deafening. When right-to-try came to Michigan, almost no one testified against it, and the Goldwater Institute was free fly in a parade of families of patients with terminal illnesses who were convinced that right-to-try would give their loved ones a shot at life. The same sort of thing happened in the Senate over S.204:

But more liberal lawmakers faced significant lobbying, featuring heartbreaking stories of young children or newlyweds facing shortened lives. Meanwhile, the most powerful opposition, the drug industry and doctors’ groups, kept their disagreement very low-profile. Their soft voices gave lawmakers little political protection for a “no” vote.

“There’s no doubt about it — there are a lot of patients out there that think this is the answer to their prayers. … They certainly believed that, and they pushed their members of Congress to support a bill that in many cases the members of Congress thought was not a good idea,” said Zuckerman.

PhRMA’s low-profile on right-to-try hurt detractors from the outset. The industry group never took a formal position on the state right-to-try laws or earlier federal proposals. But it consistently reiterated its concerns about any approach to experimental medicines that sought to bypass the FDA and the clinical trial process. Of the major drug makers, only Merck formally came out against the earlier Johnson bill.

“It’s huge,” NYU’s Bateman-House said of PhRMA’s reluctance to take a stronger public stance. “When I speak with legislators, they say, ‘Well if it’s that bad, why isn’t pharma speaking against it?’”

The same could be said of the American Society of Clinical Oncology (ASCO), which spent the last three years taking no position on right-to-try until three months ago, by which time it was too little, too late. It’s not for nothing that I once remarked sardonically that opposing right-to-try is perceived the same way as opposing mom, apple pie, and the American flag—or worse, wanting to kill mom, defile apple pie, and shred the American flag. Again, I exaggerate, but not by much.

By drafting terminally ill patients into its war with the FDA, the Goldwater Institute could basically falsely equate criticism of right-to-try with attacks on dying patients. It was a cynical and very likely intentional strategy, and it worked brilliantly to silence groups that could have been the most effective opposition to right-to-try until it was too late. But what’s wrong with right-to-try anyway? To answer that, I’ll briefly reiterate the problems with state right-to-try laws and then to discuss the problem with the federal right-to-try bill as passed.

The problem with state right-to-try laws

All the state right-to-try laws hew pretty tightly to an approved model legislation template originally developed by the Goldwater Institute. Given that, all state right-to-try laws share several major features. The first was the requirement that the disease the patient has be terminal, usually defined as having a life expectancy of less than six months, although the model legislation is more vague, requiring an “advanced disease,” defined as “progressive disease or medical or surgical condition that entails significant functional impairment, that is not considered by a treating physician to be reversible even with administration of current federal drug administration approved and available treatments, and that, without life-sustaining procedures, will soon result in death.” Various states define this condition in somewhat different ways, but you get the idea. In fact, the federal legislation uses a definition more like the latter than the former.

One of the most problematic passages, if not the most problematic passage, in all right-to-try laws, including the federal one passed by the Senate, is the definition of “investigational drug, biologic product, or device”:

“Investigational drug, biological product, or device” means a drug, biological product, or device that has successfully completed phase 1 of a clinical trial but has not yet been approved for general use by the United States food and drug administration and remains under investigation in a United States food and drug administration-approved clinical trial.

Every right-to-try bill or law I’ve read uses minor variations of the above definition. Anyone who knows anything about drug development shudders when reading passages like that. The reason is that having completed a phase 1 trial is a dangerously low bar to clear to allow more widespread use of a drug. Basically phase 1 trials are small trials, usually consisting of less than 30 subjects, that look for major toxicities and adverse events. That is not enough to determine safety, nor is it intended to. Phase I trials are designed primarily to identify major side effects and to use a process known as dose escalation to determine what is commonly referred to as the “maximum tolerated dose.” It is utterly impossible for such a small clinical trial to determine the safety of a drug. Phase II and Phase III trials are needed to confirm safety. Think of phase I trials as a screening test looking for the most obvious toxicities, with phase II and III studies confirming them. Indeed, even phase III trials can’t always adequately demonstrate that a drug is safe; it’s not uncommon for less common adverse effects not to show up until post-marketing surveillance, when much larger numbers of patients receive the drug. Moreover, only 5% of all cancer drugs that enter clinical testing are ultimately approved for patient use. Among drugs tested in phase II trials, only 30% go on to phase 3. I like to point to the cautionary example of amonifide for treating breast cancer. The drug made it through phase I trials, but serious life-threatening hematologic toxicity emerged during phase II trials.

Another problem with right-to-try laws is that they are extremely inequitable. Basically, right-to-try laws limit who can access them by wealth. The reason is that all of them have a provision that says that health insurance companies do not have to pay for right-to-try treatments and most such laws allow drug companies to charge whatever they see fit for the experimental drug. Insurance companies can pay if they so desire, but what’s the likelihood of an insurance company paying for an experimental treatment?It goes beyond that, though. If a patient uses a right-to-try drug and suffers complications, these laws basically state that the insurance company doesn’t have to pay for care resulting from that complication, and all such laws state that patients undergoing right-to-try therapies lose their coverage for hospice while undergoing right-to-try treatment. Thus, a terminally ill patient could easily go bankrupt before he died paying for drugs accessed through right-to-try laws, and many couldn’t access experimental therapeutics through such laws in any event because they simply don’t have the money or the fundraising wherewithal to do so.

Right-to-try laws also limit what patients can do in the event of malpractice or negligence. All of them immunize physicians advising or administering right-to-try medications against malpractice suits or actions against their medical license by the state medical board for doing so. All of them contain provisions broadly immunizing companies providing experimental therapeutics under right-to-try from liability. All of them contain provisions stating that state employees can’t interfere with a patient seeking right-to-try, which could be interpreted to mean that a doctor at an academic medical center at a state university couldn’t counsel a patient not to seek right-to-try without running afoul of the law. As Jann notes, even if state authorities believe, for example, that an elderly person is being exploited for financial gain by a physician, presumably this provision would prohibit their acting.

Right-to-try laws are patient-hostile in other ways, too, as Jann Bellamy and I have described many times. The most egregious example of which is how they strip patient protections away from patients who access them. One way to see this is by comparing what happens when a patient accesses an experimental therapeutic under the FDA expanded access program to what happens when another patient accesses one under a right-to-try law. Under FDA expanded access, patients retain full protections under federal and state laws. They can sue for malpractice if there is any, and their care is still monitored by an institutional review board (IRB), with any adverse events recorded and considered by the FDA. Moreover, the FDA approves nearly all such requests (99%). In contrast, under right-to-try, there is no IRB oversight. It’s all between the company and the patient.

Finally, I not infrequently call state right-to-try laws placebo legislation because such laws basically does nothing while making everyone feel better. That’s because the federal government, not the states, controls drug approval. Basically, the state can say that patients have a “right-to-try,” but only the federal government can actually guarantee such a “right.” It’s actually fortunate that state-level right-to-try laws are placebo laws, because if they actually did what’s in their text they would be profoundly harmful to patients.

The problem with the version of “right-to-try” passed by the Senate

In marked contrast to state-level laws, any federal right-to-try bill that becomes law would not be placebo legislation. It would be harmful, and the Trickett Wendler Right to Try Act of 2017, although amended to be less harmful than the original version, is still a danger to patients. I described in detail what was in the original version of this bill in previous posts; so I won’t dwell too much on it. The key points of the original bill were:

  • No interference by the federal government with state right-to-try laws.
  • No liability for either drug companies providing right-to-try or doctors recommending right-to-try
  • No use of outcomes from patients accessing right-to-try in FDA consideration of drug approval.

So let’s look at S.204 as passed by the Senate. It’s still bad, but not as bad because there are amendments that mitigate some of the worst aspects of the original. Unfortunately, it still uses an overly broad definition of who can access right-to-try. Basically, anyone with a serious illness as defined by the FDA is eligible. The bill also retains the dangerously nonsensical provision that any drug that’s passed phase I trials and is still in active development can be accessed through right-to-try.

One thing the new “right-to-try” does is to change the provision in the original version that forbade the FDA from considering outcomes observed in patients accessing a drug by right-to-try in its deliberations over whether to approve the drug or not:

(1) IN GENERAL.—Notwithstanding any other provision of this Act, the Public Health Service Act, or any other provision of Federal law, the Secretary may not use a clinical outcome associated with the use of an eligible investigational drug pursuant to this section to delay or adversely affect the review or approval of such drug under section 505 of this Act or section 351 of the Public Health Service Act unless—

(A) the Secretary makes a determination, in accordance with paragraph (2), that use of such clinical outcome is critical to determining the safety of the eligible investigational drug; or

(B) the sponsor requests use of such outcomes.

The “Secretary” above is the Secretary of Health and Human Services, although the HHS Secretary can delegate the decision to the FDA Commissioner.

The new right-to-try also requires the FDA to post information regarding right-to-try on its website:

(1) IN GENERAL.—The manufacturer or sponsor of an eligible investigational drug shall submit to the Secretary an annual summary of any use of such drug under this section. The summary shall include the number of doses supplied, the number of patients treated, the uses for which the drug was made available, and any known serious adverse events. The Secretary shall specify by regulation the dead line of submission of such annual summary and may amend section 312.33 of title 21, Code of Federal Regulations (or any successor regulations) to require the submission of such annual summary in conjunction with the annual report for an applicable investigational new drug application for such drug.

(2) POSTING OF INFORMATION.—The Secretary shall post an annual summary report of the use of this section on the internet website of the Food and Drug Administration, including the number of drugs for which clinical outcomes associated with the use of an eligible investigational drug pursuant to this section was—

(A) used in accordance with subsection (c)(1)(A);
(B) used accordance with subsection (c)(1)(B); and
(C) not used in the review of an application under section 505 of this Act or section 351 of the Public Health Service Act.

As you can see, this is better, but still problematic. Basically, the FDA Commissioner can decide on an individual basis whether or not to use right-to-try outcomes in considering the approval of a drug. I can see considerable potential for favoritism and abuse in this provision, in which favored companies can do what they like and not have to worry about whether right-to-try outcomes will count against them and less favored companies will have to worry. it is, however, good that at least there will be some transparency, as some information will have to be made publicly available.

The modified bill also softens the protections against lawsuits against manufacturers and doctors recommending right-to-try with an exception to immunity if “the relevant conduct constitutes reckless or willful misconduct, gross negligence, or an intentional tort under any applicable State law.” Now, I’m not a lawyer, but here’s one huge problem with this that I see. State right-to-try laws in general completely immunize manufacturers providing experimental therapeutics under the law and doctors recommending such therapeutics from any legal liability; so in those states there would be nothing patients could sue for, even in the case of “reckless or willful misconduct, gross negligence, or an intentional tort.” If there are any lawyers out there, feel free to correct me if I’m wrong, but it appears that only in states without right-to-try would this provision mean anything.

What now?

Now that S.204 has been passed by the Senate, it moves on to the House, where, unfortunately, it is highly likely to pass. Given the anti-regulatory mood of the current Congress, coupled with the successful branding of right-to-try opponents as either in the pocket of big pharma or indifferent to the suffering of the terminally ill, it will be very, very difficult to stop this bill. That doesn’t mean that we shouldn’t continue to try, but we should have no illusions. We are likely to see what happens if right-to-try becomes the law of the land at the federal level. While it’s true that this version is not quite as patient- and science-hostile as the original version, it is, unfortunately, plenty bad, man.

It’s also not as though we haven’t had a chance to see if right-to-try provides any of the benefits claimed for it. Unfortunately, thus far, right-to-try has been a miserable failure, despite three years for it to have proven its worth. I know. I’ve looked for “success stories,” and the Goldwater Institute has been unable to provide them.

Sandefur has, however, been able to provide the same old talking points about the FDA Expanded Access Program and about how slow the FDA allegedly is approving drugs. It actually turns out that the FDA is faster than its European counterparts approving drugs and that the expanded access program is nowhere near as onerous as ideologues like Sandefur like to paint it. Indeed, there is a nice FAQ maintained by the NYU Working Group on Compassionate Use and Pre-Approval Access that answers pretty much every talking point, and I’ve discussed these same talking points before. It’s basically a lot of misinformation promoted by ideologues.

Study: Trust in science spiked after media coverage of Zika vaccine trial [The Pump Handle]

Public trust in science is a fickle creature. Surveys show a clear majority of Americans believe science has positively impacted society, and they’re more likely to trust scientists on issues like climate change and vaccines. On the other hand, surveys also find that factors like politics, religion, age and race can greatly impact the degree of that trust. It presents a delicate challenge for agencies that depend on trust in science to do their jobs.

“Trust in science is high, but it’s not unanimous and it’s not completely unquestioned — and nor necessarily should it be,” Joseph Hilgard, an assistant professor of social psychology at Illinois State University, told me. “We assume that people don’t trust us because they don’t know what (scientists) know, but that’s not really the case. You have ideology, perspective, values — all these different lenses coming into play and that’s a great challenge for science communication.”

Hilgard is the co-author of a new study that provides some interesting insights into possible ways to improve public trust in science. The study, published in the August issue of Science Communication, is based on data collected via the Annenberg Science Knowledge survey, which began in 2016 and conducts nationwide bilingual telephone surveys on a weekly basis. Last August, the survey began collecting data on Zika virus, including an additional 500 people from the high-risk state of Florida. In examining that Zika data, researchers detected a noteworthy trend: following media coverage of a potential Zika vaccine, respondents reported greater trust in science for providing solutions to problems.

Hilgard, who at the time was a postdoctoral fellow at the Annenberg Public Policy Center, cautioned right off the bat that the findings are correlational and it’s difficult to draw any generalized implications, especially since Zika doesn’t have the polarizing effect of some other scientific issues. And unlike other Zika solutions — like aerial spraying and genetically modified mosquitoes — a vaccine is relatively uncontroversial. Still, the findings could suggest that particular circumstances are conducive to facilitating trust in science.

Hilgard and co-author Kathleen Hall Jamieson write:

A Zika vaccine has clear benefits, improving human health by preventing birth disorders, and vaccination does not conflict with mainstream public values or cultural norms. Additionally, media coverage of the Zika virus has established Zika prevention as a matter of public concern and general importance. These attributes make this news cycle a useful opportunity to observe the relationship between news of scientific progress and public attitudes toward science.

In examining answers from more than 34,000 survey responses, researchers found that in the weeks following news that a Zika vaccine had entered its first human trial, people paid more attention to Zika news and public trust in science went up. In particular, that trust bump followed increases in Google searches for “Zika vaccine” as well as news reports featuring Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, and Tom Frieden, then-director of the Centers for Disease Control and Prevention. The heightened trust lasted only two weeks, but greater attention to Zika overall lasted for six weeks.

However, the increased trust in science didn’t extend to the federal agencies tasked with Zika response and research. Within the same period of Zika vaccine news, opinions of both the National Institutes of Health and CDC remained the same. The vaccine news also had no effect on whether people felt the federal government was prepared to deal with a Zika outbreak in their community — those opinions stayed stable throughout the study period as well. Hilgard and Jamieson write:

This finding opens the possibility that confidence in science could be bolstered in a more sustained fashion by regularized communication about advances made by science. These communications may be particularly effective when they provide potential solutions to problems placed by media on the national agenda. However, such effects are likely to be relatively brief even under the best of circumstances. Additionally, such communications may backfire if the public feels that a problem or its solution is overstated for the personal benefit of scientists, politicians, or the media, although further empirical research is needed.

“This may seem like a surprise given the struggle that we sometimes have in expressing the safety of this or that treatment,” Hilgard said of the findings. “But I think it speaks to the idea that it’s not that people dislike science; it’s that they dislike certain science.”

So, what exactly fueled the heightened trust following media reports of the Zika vaccine? The study doesn’t tease those specifics out, but Hilgard had some guesses. First, while vaccine safety can be a sensitive topic, Hilgard said the actual gap in vaccine safety attitudes between scientists and the public probably isn’t as wide as we sometimes fear. Secondly, he said Zika isn’t “morally aligned.” In other words, it doesn’t lend itself to the type of morality discussions that erupted with the advent of the HPV vaccine, which prevents a sexually transmitted disease.

“Zika has very serious health implications and people are afraid of it,” he told me. “You put together fear of Zika, the acceptability of the product and the fact that there’s no real moral element to protecting yourself against Zika, and it leads to a scientific advance that, by and large, people feel good about.”

Because of such factors, Hilgard said it’s difficult to draw any generalized tips for communicating better on other scientific topics. But he did say the study suggests that keeping the public informed on new and promising scientific advances — while staying accurate and not exaggerating — could help nourish public trust.

“Science has always enjoyed a respected place in society, but it’s not unconditional love,” he said. “People want to see science earning its keep — they want know, ‘what have you done for me lately?’”

Public trust in science is a fickle creature. Surveys show a clear majority of Americans believe science has positively impacted society, and they’re more likely to trust scientists on issues like climate change and vaccines. On the other hand, surveys also find that factors like politics, religion, age and race can greatly impact the degree of that trust. It presents a delicate challenge for agencies that depend on trust in science to do their jobs.

“Trust in science is high, but it’s not unanimous and it’s not completely unquestioned — and nor necessarily should it be,” Joseph Hilgard, an assistant professor of social psychology at Illinois State University, told me. “We assume that people don’t trust us because they don’t know what (scientists) know, but that’s not really the case. You have ideology, perspective, values — all these different lenses coming into play and that’s a great challenge for science communication.”

Hilgard is the co-author of a new study that provides some interesting insights into possible ways to improve public trust in science. The study, published in the August issue of Science Communication, is based on data collected via the Annenberg Science Knowledge survey, which began in 2016 and conducts nationwide bilingual telephone surveys on a weekly basis. Last August, the survey began collecting data on Zika virus, including an additional 500 people from the high-risk state of Florida. In examining that Zika data, researchers detected a noteworthy trend: following media coverage of a potential Zika vaccine, respondents reported greater trust in science for providing solutions to problems.

Hilgard, who at the time was a postdoctoral fellow at the Annenberg Public Policy Center, cautioned right off the bat that the findings are correlational and it’s difficult to draw any generalized implications, especially since Zika doesn’t have the polarizing effect of some other scientific issues. And unlike other Zika solutions — like aerial spraying and genetically modified mosquitoes — a vaccine is relatively uncontroversial. Still, the findings could suggest that particular circumstances are conducive to facilitating trust in science.

Hilgard and co-author Kathleen Hall Jamieson write:

A Zika vaccine has clear benefits, improving human health by preventing birth disorders, and vaccination does not conflict with mainstream public values or cultural norms. Additionally, media coverage of the Zika virus has established Zika prevention as a matter of public concern and general importance. These attributes make this news cycle a useful opportunity to observe the relationship between news of scientific progress and public attitudes toward science.

In examining answers from more than 34,000 survey responses, researchers found that in the weeks following news that a Zika vaccine had entered its first human trial, people paid more attention to Zika news and public trust in science went up. In particular, that trust bump followed increases in Google searches for “Zika vaccine” as well as news reports featuring Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, and Tom Frieden, then-director of the Centers for Disease Control and Prevention. The heightened trust lasted only two weeks, but greater attention to Zika overall lasted for six weeks.

However, the increased trust in science didn’t extend to the federal agencies tasked with Zika response and research. Within the same period of Zika vaccine news, opinions of both the National Institutes of Health and CDC remained the same. The vaccine news also had no effect on whether people felt the federal government was prepared to deal with a Zika outbreak in their community — those opinions stayed stable throughout the study period as well. Hilgard and Jamieson write:

This finding opens the possibility that confidence in science could be bolstered in a more sustained fashion by regularized communication about advances made by science. These communications may be particularly effective when they provide potential solutions to problems placed by media on the national agenda. However, such effects are likely to be relatively brief even under the best of circumstances. Additionally, such communications may backfire if the public feels that a problem or its solution is overstated for the personal benefit of scientists, politicians, or the media, although further empirical research is needed.

“This may seem like a surprise given the struggle that we sometimes have in expressing the safety of this or that treatment,” Hilgard said of the findings. “But I think it speaks to the idea that it’s not that people dislike science; it’s that they dislike certain science.”

So, what exactly fueled the heightened trust following media reports of the Zika vaccine? The study doesn’t tease those specifics out, but Hilgard had some guesses. First, while vaccine safety can be a sensitive topic, Hilgard said the actual gap in vaccine safety attitudes between scientists and the public probably isn’t as wide as we sometimes fear. Secondly, he said Zika isn’t “morally aligned.” In other words, it doesn’t lend itself to the type of morality discussions that erupted with the advent of the HPV vaccine, which prevents a sexually transmitted disease.

“Zika has very serious health implications and people are afraid of it,” he told me. “You put together fear of Zika, the acceptability of the product and the fact that there’s no real moral element to protecting yourself against Zika, and it leads to a scientific advance that, by and large, people feel good about.”

Because of such factors, Hilgard said it’s difficult to draw any generalized tips for communicating better on other scientific topics. But he did say the study suggests that keeping the public informed on new and promising scientific advances — while staying accurate and not exaggerating — could help nourish public trust.

“Science has always enjoyed a respected place in society, but it’s not unconditional love,” he said. “People want to see science earning its keep — they want know, ‘what have you done for me lately?’”

Statue of Liberty, White Supremacy, and the Immigrant Question [Greg Laden's Blog]

The truth about the Statue of Liberty and that poem and everything.

The Statue of Liberty has been a symbol of American openness to immigration since it was built. However, modern White Supremacists want us to believe it was something else. I found one example of that on the Internet, writtne by Hunter Wallace with the tags “Identity” and “The Jewish Question,” and titled “David Brooks: The Great War for National Identity”:

…millions of Jews came to the United States during the Great Wave. Much of the early 20th century is the story of how these Jews rose from working class occupations into the American middle class before ascending into the highest levels of the American elite.

By the mid–20th century, America’s traditional Anglo-Protestant elite was being replaced by a more cosmopolitan New York-based Jewish elite. This new elite wasn’t and never has been exclusively Jewish (it included, for example, Catholics like the Kennedys), but was predominantly so, enough for Jewish intellectuals to have a major impact on American culture.

Around the mid–20th century, Jewish intellectuals began to change American culture and rewrite American national identity. They introduced new concepts like “racism” and new taboos like “anti-Semitism.” They concocted the myth that America was “a nation of immigrants.” Previously, Americans had no clue that there was even such a thing as “racism,” or that “anti-Semitism” was immoral, or that “we are all >…immigrants.” As Jews became more concentrated in culturally sensitive institutions (i.e., the elite news media, top universities, the entertainment media), they introduced an entirely new moral code.

The Statue of Liberty is one of my favorite examples:

“The Statue of Liberty myth provides a good case study of the shift to a post-WASP, consensus-liberal version of America. In current parlance, the Statue of Liberty is viewed as a symbol of the openness of America to immigration, and the plaque at its base by Emma Lazarus, which urges other nations to “Give me your tired, your poor, your huddled masses,” is believed to be organically connected to the statue and its liberal-universalist narrative. Unfortunately, reality is not so simple. Lazarus’s poem was not present when the statue was inaugurated in October 1886. Nor did President Grover Cleveland make any mention of the statue’s significance for immigrants in his acceptance speech.

Some Americans, especially Protestant clergymen, greeted the gift of the statue cautiously. In addition, the statue was often viewed less as a beacon for immigrants than as a guardian of American purity. As for Emma Lazarus’s oft-quoted poem, it was first erected on the interior wall of the immense statue in 1903 owing to the financial contribution of one Georgina Schuyler. Schuyler had donated the bronze plaque in memory of Lazarus, an obscure poet of Jewish ancestry whose work she admired. Not until the 1930s did the contemporary myth of a statute to immigrants arise – exactly the period in which the cosmopolitan ideas of America’s organic intellectuals were starting to win wider elite acceptance. In turn, this attitude change prompted officials to relocate Lazarus’s obscure poem to its current position at the base of the statue. …”

You can read all about this and much more in Eric P. Kaufmann’s … The Rise and Fall of Anglo-America. I highly recommend it.

Kauffman is a fairly obscure figure, but he seems to have promulgated the myth that America, as a country, was made up at the time of the American Revolution of almost entirely white British Protestants. That is a myth that ignores the non-Protestants or at least non-mainstream Protestants such as Quakers, Shakers, and various other sundry groups, Catholics, non-religious, etc. white people from Britain, all the non-British that came from Europe, all the Africans who were here non-voluntarily (about 20% of the population in the 1770s), and the Native Americans (about 100,000 within the colonial boundaries, but a strong majority in the western areas being settled at the time). White British Protestants were probably a minority in the land between the coast and the farthest extent of settlement (up to the French territories) at the time of the revolution, and that proportion of society certainly shrank further in the decades immediacy following the Revolution when additional lands occupied mainly by Native Americans, but also French and Spanish and others, were added to the US. And, it shrunk father when immigration from across Europe including many Germans, and across the rest of the world, including, obviously, more Africans, and many from the Middle East and Asia, occurred as well.

Roughly speaking, by 1790, English members of the US population was about just over half of the total, with non British Europeans being about 10%. British-Protestants may have been just barely a majority, but just. We were not a pure land of wasps at the time, or any time since.

The Statue of Liberty was at the time it was built, and is recognized today as having been built as, a monument to American Liberty, as in the American War of Independence. It dates to the centenary celebration of the Declaration of Independence, more or less. From Wikipedia:

The torch-bearing arm was displayed at the Centennial Exposition in Philadelphia in 1876, and in Madison Square Park in Manhattan from 1876 to 1882. Fundraising proved difficult, especially for the Americans, and by 1885 work on the pedestal was threatened by lack of funds. Publisher Joseph Pulitzer, of the New York World, started a drive for donations to finish the project and attracted more than 120,000 contributors, most of whom gave less than a dollar.

As part of the fundraising effort, Emma Lazarus, who was at the time heavily involved in helping refugees who had left eastern Europe under pogroms there against Jews, was asked to write an original poem. Clearly, the idea of freedom and liberty and the promise of America were tied together in the minds of all the people involved in erecting this statue, which is why the poem linked to both the statue and the fund raising was about the openness of America to receive the tired, poor, huddles masses.

The original manuscript for the poem, “The New Colossus,” is curated by the American Jewish Historical Society, which is always happy, I’m sure, to do its part in the Great American Jewish Conspiracy to annoy 21st century white supremacists.

Here is the poem:

Not like the brazen giant of Greek fame,
With conquering limbs astride from land to land;
Here at our sea-washed, sunset gates shall stand
A mighty woman with a torch, whose flame
Is the imprisoned lightning, and her name
MOTHER OF EXILES. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame.

“Keep, ancient lands, your storied pomp!” cries she
With silent lips. “Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me,
I lift my lamp beside the golden door!”

Stephen Miller, representing the White House and Donald Trump, gave the White House Press corps a pretty straight forward White Supremacist line. Me? I’d rather have the coarse and belligerant Scramucci than this guy. Well, neither, actually.

Stages of a total eclipse

Fred Espenak created this self-portrait during a 2006 total solar eclipse.

In the following excerpt from Totality – The Great America Eclipses of 2017 and 2024 – by Mark Littmann and me, Fred Espenak – we provide a handy checklist that will help you keep track of what to see, and when to look, for each of these must-see events and effects. You might even want to print this page as a handy reference for eclipse day, August 21, 2017.

First Contact – The moon begins to cover the western limb of the Sun. Remember to use safe solar filters to watch the partial phases of the eclipse.

Crescent Sun – Over a period of about an hour, the moon obscures more and more of the sun, as if eating away at a cookie. The Sun appears as a narrower and narrower crescent.

Light and Color Changes – About 15 minutes before totality, when 80% of the sun is covered, the light level begins to fall noticeably — and with increasing rapidity. The landscape takes on a metallic gray-blue hue.

Animal, Plant, and Human Behavior – As the level of sunlight falls, animals may become anxious or behave as if nightfall has come. Some plants close up. Notice how the people around you are affected.

Gathering Darkness on the Western Horizon – About 5 minutes before totality, the shadow cast by the Moon causes the western horizon to darken as if a giant but silent thunderstorm was approaching.

Temperature – As the sunlight fades, the temperature may drop perceptibly.

Shadow Bands – A minute or two before totality, ripples of light may flow across the ground and walls as Earth’s turbulent atmosphere refracts the last rays of sunlight.

Thin Crescent Sun – Only a sliver of the S\sun remains, then thinner still until . . .

Corona – Perhaps 15 seconds before totality begins, as the sun becomes the thinnest of crescents, the corona begins to emerge.

As totality ends, the sun begins to emerge from behind the moon, producing the dazzling diamond ring effect. Copyright 2016 by Fred Espenak.

Diamond Ring Effect – As the corona emerges, the crescent sun has shrunk to a short, hairline sliver. Together they form a dazzlingly bright diamond ring. Then the brilliant diamond fades into . . .

Baily’s Beads – About 3 seconds before totality begins, the remaining crescent of sunlight breaks into a string of beads along the eastern edge of the moon. These are the last few rays of sunlight passing through deep valleys at the moon’s limb, creating the momentary effect of jewels on a necklace. Quickly, one by one, Baily’s Beads vanish behind the advancing moon as totality begins.

Shadow Approaching – While all this is happening, the moon’s dark shadow in the west has been growing. Now it rushes forward and envelops you.

Second Contact Totality Begins – The sun’s disk (photosphere) is completely covered by the moon. You can now remove your solar filters and safely look directly at the eclipse.

Prominences and the Chromosphere – For a few seconds after totality begins, the moon has not yet covered the lower atmosphere of the sun and a thin strip of the vibrant red chromosphere is visible at the sun’s eastern limb. Stretching above the chromosphere and into the corona are the vivid red prominences. A similar effect occurs along the sun’s western limb seconds before totality ends.

This image of the solar corona is a High Dynamic Range composite made from 22 separate exposures. The original images were shot by Espenak in Jalu, Libya during the total solar eclipse of March 29, 2016. The USPS used this image to create the Total Eclipse of the Sun, Forever® stamp.

Corona Extent and Shape – The corona and prominences vary with each eclipse. How far (in solar diameters) does the corona extend? Is it round or is it broader at the sun’s equator? Does it have the appearance of short bristles at the poles? Look for loops, arcs, and plumes that trace solar magnetic fields.

Planets and Stars Visible – Venus and Mercury are often visible near the eclipsed sun, and other bright planets and stars may also be visible, depending on their positions and the sun’s altitude above the horizon.

Landscape Darkness and Horizon Color – Each eclipse creates its own level of darkness, depending mostly on the moon’s angular size. At the far horizon all around you, beyond the moon’s shadow, the sun is shining and the sky has twilight orange and yellow colors.

Temperature – Is it cooler still? A temperature drop of about 10°F (6°C) is typical. The temperature continues to drop until a few minutes after third contact.

Animal, Plant, and Human Reactions – What animal noises can you hear? How are other people reacting? How do you feel?

End of Totality Approaching – The western edge of the moon begins to brighten and vividly red prominences and the chromosphere appear. Totality will end in seconds.

Third Contact – One bright point of the sun’s photosphere appears along the western edge of the moon. Totality is over. The stages of the eclipse repeat themselves in the reverse order.

Baily’s Beads – The point of light becomes two, then several beads, which fuse into a thin crescent with a dazzling bright spot emerging, a farewell diamond ring.

Diamond Ring Effect and Corona – As the diamond ring brightens, the corona fades from view. Daylight returns.

Shadow Rushes Eastward

Shadow Bands Reappear – Shadow Bands may be seen during the first 1-2 minutes after totality ends.

Crescent Sun – Partial phases occur in reverse order. Once again, you must use your solar filter to watch all the partial phases of the eclipse.

Recovery of Nature Partial Phase – Flowers open up, animals return to normal behavior, daylight regains its strength.

Fourth Contact – The moon no longer covers any part of the sun. The eclipse is over.

Learn all about the Best Ways to View the Solar Eclipse and well as what it is like to Experience Totality.

Where’s the moon? Waxing gibbous

Waxing gibbous moon via Clarise Samuels in Montreal. She used multiple exposures to superimpose the moon on a close-up of small light bulbs and she wrote: “It would be nice if we had a lot of moons.” Wannabe meteor-watchers will disagree!

Those who want to watch the annual Perseid meteor shower are now shaking their fists at this week’s waxing gibbous moon. It’s more than half-lighted, less than full, but steadily waxing toward full moon on the night of August 7-8, 2017. Afterwards, the moon will be waning, but still bright in the sky after midnight during the Perseids’ peak. As if in consolation (although not for us in the Americas), the upcoming full moon will feature a partial lunar eclipse, visible from Earth’s Eastern Hemisphere on the night of August 7-8. And of course this cycle of the moon is moving us inexorably toward the much-anticipated total eclipse of the sun on August 21, which will cut a narrow (and likely crowded!) swath across the U.S.

This week’s waxing gibbous moon rises during the hours between noon and sunset. It sets in the wee hours after midnight. It falls between a first quarter moon and a full moon.

Any moon that appears more than half lighted but less than full is called a gibbous moon. The word gibbous comes from a root word that means hump-backed.

People often see a waxing gibbous moon in the afternoon, shortly after moonrise, while it’s ascending in the east as the sun is descending in the west. It’s easy to see a waxing gibbous moon in the daytime because, at this phase of the moon, a respectably large fraction of the moon’s dayside is now facing our way.

A gibbous moon can also be a waning gibbous, in the week between full moon and last quarter moon. Want to know more? Check out our post offering 4 keys to understanding moon phases.

Waxing gibbous moon via Clarise Samuels in Montreal. She used multiple exposures to superimpose the moon on a close-up of small light bulbs and she wrote: “It would be nice if we had a lot of moons.” Wannabe meteor-watchers will disagree!

Those who want to watch the annual Perseid meteor shower are now shaking their fists at this week’s waxing gibbous moon. It’s more than half-lighted, less than full, but steadily waxing toward full moon on the night of August 7-8, 2017. Afterwards, the moon will be waning, but still bright in the sky after midnight during the Perseids’ peak. As if in consolation (although not for us in the Americas), the upcoming full moon will feature a partial lunar eclipse, visible from Earth’s Eastern Hemisphere on the night of August 7-8. And of course this cycle of the moon is moving us inexorably toward the much-anticipated total eclipse of the sun on August 21, which will cut a narrow (and likely crowded!) swath across the U.S.

This week’s waxing gibbous moon rises during the hours between noon and sunset. It sets in the wee hours after midnight. It falls between a first quarter moon and a full moon.

Any moon that appears more than half lighted but less than full is called a gibbous moon. The word gibbous comes from a root word that means hump-backed.

People often see a waxing gibbous moon in the afternoon, shortly after moonrise, while it’s ascending in the east as the sun is descending in the west. It’s easy to see a waxing gibbous moon in the daytime because, at this phase of the moon, a respectably large fraction of the moon’s dayside is now facing our way.

A gibbous moon can also be a waning gibbous, in the week between full moon and last quarter moon. Want to know more? Check out our post offering 4 keys to understanding moon phases.
