Our new Pioneer Awards funding scheme – high-risk, high-reward, high-impact

Prof Nic Jones

A year ago we published our latest Research Strategy, setting out how we intend to continue, and capitalise on, our rapidly exploding understanding of cancer.

The Strategy aimed to address a key question: how can we convert this accelerating scientific progress into improvements that make a real difference for people affected by the disease?

A key realisation we had was that ‘more of the same’ wasn’t good enough – we had to look at how to fund completely new areas of science, while making sure that the conventional high-quality laboratory and clinical cancer research we’ve always supported, can have even wider impact.

A year on, we can look back proudly on the successful launch of six new funding schemes, covering a range of different areas – mid-career help for up-and-coming scientists; funding to discover new ‘biological’ therapies and understand the immune system; a focus on multidisciplinary research – involving engineers and physicists – and on preventing cancer; and funding aimed at improving collaboration between our existing Centres.

We also launched an ambitious new Grand Challenge which, next year, will hand £20million to an international consortium of scientists, to solve a key question in cancer research.

And today, we’ve announced another new funding scheme to the UK research community: the Pioneer Award.

A ‘Dragons Den’ approach

When we spoke to the research community about how we could best help them make faster progress, two things cropped up again and again: many didn’t think we took enough risks in what we funded. And others said it could sometimes take too long to apply for funding – especially for smaller, more innovative projects.

The Pioneer Awards – launched this week at our biennial researchers’ get-together by our chief scientist, Professor Nic Jones – aims to address these concerns.

As of today, any researchers, no matter what their background or track record, will be able to pitch their ideas to our cross-disciplinary Pioneers Committee. We’re particularly keen to hear from people outside of biological and clinical science – for example, technology experts, software developers, or behavioural scientists.

We won’t require extensive, lengthy documentation up front – just a two-side outline of the idea, submitted anonymously, and why it will make a real difference in cancer.

The Committee will short-list the ideas they receive on a regular basis, and successful applicants will then be invited to pitch their idea, in person, to the panel.

“It’s almost like a Dragon’s Den approach,” Professor Jones told the audience.

If their idea is deemed scientifically credible, they’ll receive grants of up to £200,000, to cover two-year-long research projects.

This isn’t to replace any of our other funding schemes. It’s to fund high-risk, high-reward projects that wouldn’t be able to happen otherwise.

“We don’t know what we’re going to get,” Professor Jones remarked at the launch. “That’s the whole point of it. Not all of it will work – this is high risk stuff, I’m really excited that Cancer Research UK is doing this. If just a couple of the awards take off, it could be transformational for the field.”

The Committee members are excited too. Dr Helen Lee works on developing diagnostic tests for HIV and Chlamydia at the University of Cambridge’s Diagnostics Development Unit, and is also President and CEO of spin-out company Diagnostics for the Real World.

“I was very impressed by Cancer Research UK for launching this unique and innovative scheme,” she told us.

“The speed of the application process, availability to a breadth of new research audiences, and levelling the playing field by judging applications which are anonymous are all positive features which will increase the chance of funding some truly ground-breaking cancer research.”

“There’s nothing quite like it in the UK.”

The funding scheme is now open – you can read more about it on our website, and we’ll keep you updated with details of what it ends up funding as decisions are made.

When traditional medicine doesn’t help, does integrative medicine provide answers? [Respectful Insolence]

Sometimes, I think advocates of “integrative” medicine are trolling me. Of course, unlike antivaccine advocates, I realize it (usually) isn’t about me at all and they’re just writing what they believe and have (usually in the vast majority of cases) never encountered me and (usually in the vast majority of cases) aren’t considering me at all. Even so, it’s hard, when coming across an article like The Power of Integrative Medicine When All Else Fails by Emma M. Seppälä over on Psychology Today, not to think that I’m being trolled, so blatant are the alternative medicine propaganda and apologia. As if the title weren’t bad enough, check out the tag line:

When traditional medicine doesn’t help, integrative medicine provides answers.

Regular readers and commenters of this very blog can probably predict Orac’s reaction to this.

It begins, as do so many of these sorts of articles, with an anecdote, a human interest story. In this case, it’s a woman named Stacy Brindise, who, for whatever reason, was having problems with infertility. She and her husband Mike had been trying to conceive for several years and failing. They had what is called “unexplained infertility,” which usually means the man has adequate sperm count and quality, while the woman is ovulating normally. In other words, there doesn’t appear to be a medical explanation, either on the male or female side, for the infertility. Like many couples in this predicament, the Brindises underwent a steady escalation, from hormone treatments for Stacy, to monthly intrauterine insemination, which both failed.

The next step was to be in vitro fertilization (IVF), which starts at $12,000 a round and is usually not covered by medical insurance. This story was the hook, and we’re left with this:

Nothing had worked and it was time, Stacy decided, to change her approach.

“When people have a medical problem, everybody seems to jump right to drugs as the solution,” she says. “I wanted to see if improving my overall health and well-being would increase our chances of getting pregnant naturally.”

I say the story of the Brindises is the hook because the first part of it is told at the beginning, and they are not revisited until the very end of the article. Spoiler alert: We don’t learn about what happened to the Brindises until the end, but these sorts of stories (particularly if they involve infertility) are so utterly predictable that it isn’t really a spoiler at all to reveal right now that Stacy ultimately got pregnant and credits acupuncture. More on that later. First, let’s get to the propaganda between the beginning and end of the Brindises’ story:

Stacy is not alone in her gut feeling that first addressing her overall health and well-being—before investing in more invasive solutions—might be a key element in her health care. High-tech, high-cost approaches clearly have their place, and modern medicine can boast many silver-bullet solutions, but millions of Americans feel that’s not enough. They spend more than $30 billion a year out of their own pockets for alternative treatments, according to data compiled by the National Center for Complementary and Alternative Medicine. Funding for NCCAM—the U.S. government’s “lead agency for scientific research on complementary and alternative medicine”—hit $128 million in 2012, a 156% increase since its inception in 1999.

Even though this article is dated June 30, 2015, one wonders when Dr. Seppälä wrote it. As you all know, it’s no longer called NCCAM—and hasn’t been for more than six months. In December, NCCAM was reborn as the National Center for Complementary and Integrative Health (NCCIH, an acronym that doesn’t flow off the tongue as nice and easy as NCCAM did). Dr. Seppälä needs to get hip with the times. It’s no longer “complementary and alternative medicine” (CAM, another acronym that slides easily off the tongue), but “integrative medicine,” because the nasty word “alternative” has to be banished if the practice of “integrating” quackery into real medicine is to proceed apace. Of course, it remains depressing that the NCCIH budget remains in the $120-130 million range. I suppose the only good thing about the currently stagnant NIH budget is that the NCCIH budget has remained stagnant as well; on the other hand, that’s roughly $125 million that doesn’t go to real research.

In any case, now seems as good a time as any to repeat my rather clear position that NCCIH should be dissolved and its component parts absorbed back into various appropriate NIH centers and institutes. Upon its founding, the reason for its existence was to study alternative or (“unconventional”) medicine, the intent of its primary sponsor, Senator Tom Harkin, being that it “validate” such practices. We’re not just talking about unproven practices that might have some plausibility, such as supplements (which could contain pharmacologically active ingredients) or yoga (which is really just a form of exercise that has been co-opted as somehow “alternative” because it’s, you know, Asian in origin). Indeed, Sen. Harkin became most displeased with NCCAM in 2009, saying that it had “fallen short” because it had failed, as he put it, to validate any alternative medicine. Of course, it never occurred to him that perhaps the reason for this is because there was nothing there to be “validated.” Be that as it may, given that the director of NCCIH, Dr. Josephine Briggs, has promised not to emphasize the sorts of studies that were so widely derided before (such as studies of homeopathy, distant healing, and the like) and, as I like to characterize her view expressed in the 2011-2105 NCCAM strategic plan, do some real science for a change, there really is no reason for NCCIH to exist any more. Its real reason for existence was to provide scientific cover for the more outrageous forms of alternative medicine, and it has failed at that.

Not that that stops Dr. Seppälä from writing:

In 2010, 600 health care professionals assembled in Washington, D.C., for a summit on integrative medicine. It was sponsored by the Institute of Medicine, which defines integrative medicine as “health care that addresses together the mental, emotional, and physical aspects of the healing process for improving the breadth and depth of patient-centered care and promoting the nation’s health.”

The doctors who champion integrative approaches are not simply proposing “alternatives.” They advocate an updated model of health care that integrates mind and body, promotes more interaction and communication in the doctor-patient relationship, puts the patient at the center, and encourages self-care.

First off, the only thing this conference is an indication of is just how entrenched and successful advocates of “integrating” quackery into science-based medicine have been. Second, and more importantly, this is nothing more than the same old trope that you somehow have to embrace quackery in order to “put the patient at the center,” “promote more interaction and communication in the doctor-patient relationship,” and “encourage self-care.” Basically, it’s a false dichotomy that says, in order to become a more “holistic” physician and achieve these three things, you have to embrace woo, including, apparently, mind-body dualism, a concept implied by the frequent use of the term “mind-body” in various “integrative” methods. There’s nothing “updated” about this model of health care, because a good primary care doctor practicing science-based medicine should be a wholistic doctor who does all these things. There is no need to embrace unproven supplements or treatments based on mysticism and prescientific beliefs about medicine, such as acupuncture (or virtually anything other than scientifically validated natural products) from traditional Chinese medicine or “energy medicine,” such as reiki or healing touch, to achieve this. Nor is it necessary to “rebrand” perfectly science-based modalities such as diet and exercise (which is all yoga and Tai Chi, for example, are, forms of exercise) as somehow being “alternative” or “integrative” to achieve this.

Before we get back to the Brindises, though, Dr. Seppälä relates two more anecdotes. The first is a woman named Florence Strang, who is a breast cancer survivor. The treatment of her breast cancer required, as many breast cancers often do, chemotherapy and radiation and credits “mindfulness” with getting through it. Here’s the thing. There’s really nothing particularly “alternative” (back when it was CAM) or “integrative” (now that it’s part of “integrative medicine”) about mindfulness, which is in psychology an approach to reduce cognitive vulnerability to stress and emotional distress. If mindfulness turns out to be a useful psychological strategy to reduce distress, it will be validated by science. Again, it is a false dichotomy to consider it “alternative.” To paraphrase Tim Minchin, there is no such thing as alternative medicine. What do you call alternative medicine that’s been proven to work by science? Medicine! And “alternative” medicine that’s been validated by science will be naturally integrated into medicine, no need for a separate label.

Also, no need for woo-speak:

Strang’s way of coping with her cancer reflects the approach that integrative health care doctors take, according to Dr. Margaret Chesney, director of the Osher Center for Integrative Medicine at the University of California-San Francisco. Chesney emphasizes that the best way to enhance health and heal illness is often a combination of conventional medicine and healing methods that “address the person as a whole, that see where they are in their lives from the point of view of mind, body, spirit, and community.” For a patient at the Osher Center who wants to prevent heart disease, for example, the treatment plan might include an appointment with a cardiologist for appropriate testing but also a stress-management program such as yoga, meditation, or massage.

Once again, you do not need to embrace woo in order to “treat the whole patient.” Wait, you say. Yoga, meditation, and massage are not necessarily woo. I would (mostly agree). Yoga is just a form of exercise, at least when it’s stripped of its mystical practices. Massage is just something that feels good; calling it therapy medicalizes something that doesn’t really need to be medicalized. That’s a complaint that I have about much of “integrative” health practices. Modalities that once were just viewed as supportive services, things to help patients pass the time in the hospital or to take their minds off of things, either in or out of the hospital, have now become “treatments” or “therapy”; i.e., unnecessarily medicalized. I also note that the Osher Center at UCSF offers a lot more than just yoga, meditation, and massage. It offers acupuncture, traditional Chinese Medicine, and Ayurveda, among other unscientific therapies. Funny how supporters of integrative medicine tend not to mention these other things when promoting their centers.

The other anecdote is that of a veteran named Richard Low, who suffered severe post-traumatic stress disorder (PTSD) after 16 months in Iraq as an officer in the 4th Battalion of the 23rd Infantry Regiment. He learned to practice yoga, and apparently it helped him deal with his PTSD. So far, not so bad. Unfortunately, right after that Dr. Seppälä touts pure nonsense:

Shad Meshad, founder of the National Veterans Foundation, was instrumental in bringing attention to post-traumatic stress disorder before it was a clinically acknowledged diagnosis. He is internationally renowned for his work with trauma and was asked by the U.S. government to train critical-incident and trauma teams after the 9/11 attacks. Meshad uses a technique called TFT, in which a practitioner asks the patient to recall a traumatic event, then helps them tap different parts of the body known as meridian points (mostly on the face) in order to release the trauma. This practice is often coupled with breathing practices.

What is TFT, I wondered? Actually, I knew. Odd that Dr. Seppälä didn’t call the treatment what its abbreviation stands for: Thought Field Therapy. TFT is, actually, a form of “energy medicine” based on the traditional Chinese medicine concept of qi. It’s even spawned an offshoot, EFT, or emotional freedom techiques. Basically, Meshad left out a very big part of what TFT really is:

The theory behind TFT is that negative emotions cause energy blockage and if the energy is unblocked then the fears will disappear. Tapping acupressure points is thought to be the means of unblocking the energy. Allegedly, it only takes five to six minutes to elicit a cure. Dr. Callahan claims an 85% success rate. He even does cures over the phone using “Voice Technology” on infants and animals; by analyzing the voice he claims he can determine what points on the body the patient should tap for treatment.

Brandon A. Gaudiano and James D. Herbert wrote an excellent overview of TFT in Skeptical Inquirer 15 years ago:

Despite extraordinary claims to the contrary, TFT is not supported by scientific evidence. The theoretical basis of TFT is grounded in unsupported and discredited concepts including the Chinese philosophy of chi and Applied Kinesiology. Many of the practices of TFT proponents are much more consistent with pseudoscience than science. Controlled studies evaluating the efficacy of TFT will be required for the treatment to be taken seriously by the scientific community.

Nothing has changed regarding the evidence for TFT in 15 years. It’s quackery.

What article like this would be complete without an appeal to “empowering the patient? Yes, it’s there:

The power of integrative medicine doesn’t just lie in techniques. According to Dr. David Spiegel, director of the Center on Stress and Health at Stanford University, part of what’s powerful about any integrative approach is that it helps patients feel more involved, more in control and responsible for their own health care. It also allows for more time with a medical practitioner. “The average doctor,” says Spiegel, “spends seven minutes per patient and the average integrative practitioner spends 30 minutes.”

My common response to this is simple. You don’t have to embrace pseudoscience and quackery like TFT in order to “empower” the patient and make him feel “more involved, more in control and responsible for their own health care.” It’s the false dichotomy at the heart of “integrative medicine.” (More on that tomorrow, when I will discuss another annoying article of this ilk.)

After this detour through steadily increasing levels of quackery, from non-quackery (yoga) to pure quackery (TFT), Seppälä finally makes it back to the Brindises:

It was a friend of Stacy’s who helped the Brindises solve their unexplained infertility. She was a nurse in an obstetrician’s office and she told Stacy that she had met many women who had used acupuncture successfully when they were trying to get pregnant. Despite some misgivings about the little she knew about acupuncture—namely, that it involved a lot of tiny needles—Stacy booked an appointment at the Acupuncture and Chinese Medical Center in Edina, Minnesota.

“My first surprise was that the doctor spent a good hour and a half with me,” Stacy says. “She asked me detailed questions about my eating habits, stress levels, and lifestyle. She took the time to get to know all of my habits so I could make choices that were more conducive to pregnancy. Her assessing my overall well-being made me feel really comfortable and taken care of.”

The acupuncturist advised once-a-week acupuncture sessions and dietary adjustments. Five weeks later, Stacy got her second surprise: She was pregnant. Stacy and Mike welcomed a healthy baby boy into the world in November.

There is no good evidence that acupuncture has anything to do with helping infertile couples conceive or, as it’s often touted to do, improving success rates for IVF or help polycystic ovary syndrome, a common cause of female infertility. Indeed, as happy as one might be for the Brindises having managed to have a child after trying for so long, there is no good evidence that acupuncture improves fertility. (Why should it? There’s no plausible reason why it should, and science bears out that the prediction that it shouldn’t.) Ditto other alternative treatments. Yet, typically anecdotes like the Brindises are presented as slam-dunk examples of the benefits of acupuncture and other “integrative” medicine, when in fact they are examples of tooth fairy science. Acupuncture does not work.

It’s depressing to see an article such as this in Psychology Today. I had never heard of Dr. Seppälä before this; so I took a look at her profile. She is Science Director of the Center for Compassion and Altruism Research and Education at Stanford University. Oddly enough, for holding such a position, she only has three publications listed on PubMed. But she does do this:

In addition to her work at Stanford, she founded Fulfillment Daily (http://ift.tt/1y64XZ0 (link is external)), a magazine on science-based news for a happier life. She is also a popular Psychology Today blogger and contributor to a number of press outlets such as Scientific American Mind, the Huffington Post, Mindful and Spirituality & Health magazines. She often teaches Science of Well-being workshops in university and corporate setting and is a speaker with BrightSight group.

In other words, she appears to be a self-help guru, who mostly publishes in non-peer-reviewed sources and does a lot of talks and workshops. Whatever her role is, Dr. Seppälä has credulously contributed to the spin that promotes integrative medicine as somehow the way to empower patients and provide “holistic care.” It’s a common message that is the primary driver of the growing popularity of integrative medicine. It’s not true that when traditional medicine doesn’t help, integrative medicine provides answers, nor is it necessary to embrace pseudoscience to get those answers.

Modalities that once were just viewed as supportive services, things to help patients pass the time in the hospital or to take their minds off of things, either in or out of the hospital, have now become “treatments” or “therapy”; i.e., unnecessarily medicalized. I also note that the Osher Center at UCSF offers a lot more than just yoga, meditation, and massage. It offers acupuncture, traditional Chinese Medicine, and Ayurveda, among other unscientific therapies. Funny how supporters of integrative medicine tend not to mention these other things when promoting their centers.

The other anecdote is that of a veteran named Richard Low, who suffered severe post-traumatic stress disorder (PTSD) after 16 months in Iraq as an officer in the 4th Battalion of the 23rd Infantry Regiment. He learned to practice yoga, and apparently it helped him deal with his PTSD. So far, not so bad. Unfortunately, right after that Dr. Seppälä touts pure nonsense:

Shad Meshad, founder of the National Veterans Foundation, was instrumental in bringing attention to post-traumatic stress disorder before it was a clinically acknowledged diagnosis. He is internationally renowned for his work with trauma and was asked by the U.S. government to train critical-incident and trauma teams after the 9/11 attacks. Meshad uses a technique called TFT, in which a practitioner asks the patient to recall a traumatic event, then helps them tap different parts of the body known as meridian points (mostly on the face) in order to release the trauma. This practice is often coupled with breathing practices.

What is TFT, I wondered? Actually, I knew. Odd that Dr. Seppälä didn’t call the treatment what its abbreviation stands for: Thought Field Therapy. TFT is, actually, a form of “energy medicine” based on the traditional Chinese medicine concept of qi. It’s even spawned an offshoot, EFT, or emotional freedom techiques. Basically, Meshad left out a very big part of what TFT really is:

The theory behind TFT is that negative emotions cause energy blockage and if the energy is unblocked then the fears will disappear. Tapping acupressure points is thought to be the means of unblocking the energy. Allegedly, it only takes five to six minutes to elicit a cure. Dr. Callahan claims an 85% success rate. He even does cures over the phone using “Voice Technology” on infants and animals; by analyzing the voice he claims he can determine what points on the body the patient should tap for treatment.

Brandon A. Gaudiano and James D. Herbert wrote an excellent overview of TFT in Skeptical Inquirer 15 years ago:

Despite extraordinary claims to the contrary, TFT is not supported by scientific evidence. The theoretical basis of TFT is grounded in unsupported and discredited concepts including the Chinese philosophy of chi and Applied Kinesiology. Many of the practices of TFT proponents are much more consistent with pseudoscience than science. Controlled studies evaluating the efficacy of TFT will be required for the treatment to be taken seriously by the scientific community.

Nothing has changed regarding the evidence for TFT in 15 years. It’s quackery.

What article like this would be complete without an appeal to “empowering the patient? Yes, it’s there:

The power of integrative medicine doesn’t just lie in techniques. According to Dr. David Spiegel, director of the Center on Stress and Health at Stanford University, part of what’s powerful about any integrative approach is that it helps patients feel more involved, more in control and responsible for their own health care. It also allows for more time with a medical practitioner. “The average doctor,” says Spiegel, “spends seven minutes per patient and the average integrative practitioner spends 30 minutes.”

My common response to this is simple. You don’t have to embrace pseudoscience and quackery like TFT in order to “empower” the patient and make him feel “more involved, more in control and responsible for their own health care.” It’s the false dichotomy at the heart of “integrative medicine.” (More on that tomorrow, when I will discuss another annoying article of this ilk.)

After this detour through steadily increasing levels of quackery, from non-quackery (yoga) to pure quackery (TFT), Seppälä finally makes it back to the Brindises:

It was a friend of Stacy’s who helped the Brindises solve their unexplained infertility. She was a nurse in an obstetrician’s office and she told Stacy that she had met many women who had used acupuncture successfully when they were trying to get pregnant. Despite some misgivings about the little she knew about acupuncture—namely, that it involved a lot of tiny needles—Stacy booked an appointment at the Acupuncture and Chinese Medical Center in Edina, Minnesota.

“My first surprise was that the doctor spent a good hour and a half with me,” Stacy says. “She asked me detailed questions about my eating habits, stress levels, and lifestyle. She took the time to get to know all of my habits so I could make choices that were more conducive to pregnancy. Her assessing my overall well-being made me feel really comfortable and taken care of.”

The acupuncturist advised once-a-week acupuncture sessions and dietary adjustments. Five weeks later, Stacy got her second surprise: She was pregnant. Stacy and Mike welcomed a healthy baby boy into the world in November.

There is no good evidence that acupuncture has anything to do with helping infertile couples conceive or, as it’s often touted to do, improving success rates for IVF or help polycystic ovary syndrome, a common cause of female infertility. Indeed, as happy as one might be for the Brindises having managed to have a child after trying for so long, there is no good evidence that acupuncture improves fertility. (Why should it? There’s no plausible reason why it should, and science bears out that the prediction that it shouldn’t.) Ditto other alternative treatments. Yet, typically anecdotes like the Brindises are presented as slam-dunk examples of the benefits of acupuncture and other “integrative” medicine, when in fact they are examples of tooth fairy science. Acupuncture does not work.

It’s depressing to see an article such as this in Psychology Today. I had never heard of Dr. Seppälä before this; so I took a look at her profile. She is Science Director of the Center for Compassion and Altruism Research and Education at Stanford University. Oddly enough, for holding such a position, she only has three publications listed on PubMed. But she does do this:

In addition to her work at Stanford, she founded Fulfillment Daily (http://ift.tt/1y64XZ0 (link is external)), a magazine on science-based news for a happier life. She is also a popular Psychology Today blogger and contributor to a number of press outlets such as Scientific American Mind, the Huffington Post, Mindful and Spirituality & Health magazines. She often teaches Science of Well-being workshops in university and corporate setting and is a speaker with BrightSight group.

In other words, she appears to be a self-help guru, who mostly publishes in non-peer-reviewed sources and does a lot of talks and workshops. Whatever her role is, Dr. Seppälä has credulously contributed to the spin that promotes integrative medicine as somehow the way to empower patients and provide “holistic care.” It’s a common message that is the primary driver of the growing popularity of integrative medicine. It’s not true that when traditional medicine doesn’t help, integrative medicine provides answers, nor is it necessary to embrace pseudoscience to get those answers.

Stars’ spiral arms cradle baby planets

A new study from the Carnegie Institution for Science in Washington D.C. offers a potential solution to the question of how small rocky planets like our Earth come to be. A puzzle relates to how dust grains in a disk around a newly forming star avoid being dragged into the star before enough of the grains stick together to have strong-enough gravity to begin pulling in more grains … and ultimately grow into planets. Published in the Astrophysical Journal on June 25, 2015, lead researcher Alan Boss shows in his theoretical study that newly forming stars, called protostars, can scatter small rocky bodies outward during periods of “gravitational instability” in the disk. Boss’ work links this phase of instability with spiral arms now known to exist around some young stars.

According to modern theories about how rocky planets form, during the infant stages of star formation, disks of gas and dust surround protostars. These are called protoplanetary disks. The dust and debris in the disks collide and coalesce, slowly gaining mass and gravity, eventually becoming planetesimals, which are small bodies that fuse with others in order to create planets.

Previous theoretical models have been unable to explain how the planetesimals – mainly those between 1 and 10 meters in radius – resisted being pulled inward and consumed by what’s called gas drag from the star. If too many small bodies are lost to gas drag, there would not be enough left to form orbiting planets.

Observations of other young stars reveal that those similar in size to our sun undergo periodic explosive bursts, each lasting about 100 Earth-years. During these outbursts, a star’s luminosity is seen to increase, and astronomers believe the outbursts are linked to a period of “gravitational instability” in the disk.

Boss’s latest work shows that this phase in the life of a newly forming star can scatter the vulnerable 1- to 10-meter bodies outward and away from the star, thereby preventing them from falling into the star and becoming lost.

A statement from Carnegie Institution for Science explained:

Recent work has shown the presence of spiral arms around young stars, similar to those thought to be involved in the short-term disruptions in the disk.

The gravitational forces of these spiral arms could scatter outward the problematic boulder-sized bodies, allowing them to accumulate rapidly to form planetesimals large enough that gas drag is no longer a problem.

Boss’s modeling techniques hone in on the idea that spiral arms might be able to answer the question of how a developing solar system avoids losing too many larger bodies before the boulders have a chance to grow into something bigger.

Boss added:

While not every developing protostar may experience this kind of short-term gravitational disruption phase, it is looking increasingly likely that they may be much more important for the early phases of terrestrial [rocky] planet formation than we thought.

Boss’ model focuses on the significance of spiral arms and lends a new perspective to the formation of our solar system, as well as solar systems throughout our Milky Way galaxy.

Ask Ethan #95: Could it all come crashing down? (Synopsis) [Starts With A Bang]

“Revolutions are something you see only in retrospect.” –Alan Greenspan

If there’s one thing you can be certain of when it comes to the fundamental, scientific truths of our Universe, it’s this: someday, in the not too distant future, those truths will be superseded by more fundamental ones. And even those, quite likely, won’t be the final truths, but just one step further along the line towards our understanding of reality.

Does this mean that we’ve necessarily got it all wrong, and that we might just as well ignore the successes of our best theories so far? Does it mean that all we know about the Universe could easily be upended and replaced, leading to vastly different conclusions to questions like where everything came from?

A new coffee table book with horses and men with beards. [Greg Laden's Blog]

Unbranded is the story of four guys and a small herd of mustangs who traveled three thousand miles across the American west. From author Ben Masters web site:

Ben Masters is the “mastermind” of Unbranded. In 2010, he and two friends completed a 2,000-mile ride along the Continental Divide. They were broke at the time and adopted some $125 mustangs from the Bureau of Land Management to supplement their string of quarter horses. They were surprised to find the mustangs outperformed the domestic horses. Intrigued, Masters looked into the wild horse controversy and found a sad and complex situation: 50,000 unwanted wild horses and burros living in government-leased pens and pastures and in need of permanent homes. He decided to do something about it. The Unbranded idea was born.

Masters recruited riders Jonny Fitzsimons, Thomas Glover, and Ben Thamer to join him on his quest and brought Director Phillip Baribeau on board to guide the film’s production. Masters then inspired and persuaded organizations and individuals from around the world to join the Unbranded mission, which resulted in a successful Kickstarter campaign and crucial funding for the project. During the ride, Masters was charged with the mapping and logistics for sixteen horses, four Aggies, and three alternating cameramen traveling through unpredictable terrain with changing landowners, agencies, and restrictions.

A native Texan, Masters graduated from Texas A&M with a degree in wildlife biology. During college, he attended classes in the spring, led horseback rides in Yellowstone during the summer, guided Wyoming elk hunts in the fall, and managed the Jacalon Ranch in South Texas over the winter. Masters, who is CEO of Fin & Fur Films, LLC, is an accomplished photographer, an experienced horse trainer and packer, a dedicated conservationist, and main author of the book Unbranded.

If you are into horses, or the American west, it is a great story. Even better, if you know someone who is, this is a great gift book because it is a well produced, coffee-table class book.

Star of the week: Antares is Heart of the Scorpion

Bright reddish Antares – also known as Alpha Scorpii – is easy to spot on a summer night. It is the brightest star – and distinctly reddish in color – in the fishhook-shaped pattern of stars known as the constellation Scorpius the Scorpion. Follow the links below to learn more about this wonderful star.

How to see Antares

Antares science

Antares in history and myth

Scorpius is one of the few constellations that looks like its namesake. The bright red star Antares marks the Scorpion's Heart. Notice also the two stars at the tip of the Scorpion's Tail. They are known as The Stinger.

How to see Antares. If you look southward in early evening from late spring to early fall, you’re likely to notice the fishhook pattern of Scorpius the Scorpion, with ruby Antares at its heart. If you think you’ve found Antares, aim binoculars in its direction. You should notice its reddish color. And you should see a little star cluster – known as M4 – just to the right of this star. (See images above)

Antares is the 16th brightest star in the sky, and it is located in the southern half of Earth’s sky. So your chance of seeing this star on any given night increases as you go farther southward on Earth’s globe. If you traveled to the southern hemisphere – from about 67 degrees south latitude – you’d find that Antares is circumpolar, meaning that it never sets and is visible every night of the year from Earth’s southernmost regions.

We in the northern hemisphere know Antares better than several other southern stars that are brighter. That’s because Antares is visible from throughout most of the northern hemisphere, short of the Arctic. Well, not quite the Arctic, but anywhere south of 63 degrees north latitude can – at one time or another – see Antares. (Helsinki yes, Fairbanks, no)

The midnight culmination of Antares is on or near June 1. That is when Antares is highest in the sky at midnight (midway between sunset and sunrise). It is highest in the sky at about dawn in early March and at about sunset in early September.

If Antares replaced the sun in our solar system, its surface would extend beyond the orbit of the fourth planet, Mars. Here, Antares is shown in contrast to another star, Arcturus, and our sun.

Antares science. Antares is truly an enormous star, with a radius in excess of 3 Astronomical Units (AU). One AU is the Earth’s average distance from the sun. If by some bit of magic Antares was suddenly substituted for our sun, the surface of the star would extend well past the orbit of Mars!

Antares is classified as an M1 supergiant star. The M1 designation says that Antares is reddish in color and cooler than many other stars. Its surface temperature of 3500 kelvins (about 5800 degrees F.) is in contrast to about 10,000 degrees F. for our sun.

Even though Antares’ surface temperature is relatively low, Antares’ tremendous surface area – the surface from which light can escape – makes this star very bright. In fact, Antares approaches 11,000 times the brilliance of our puny sun, a G2 star.

But that is just in visible light. When all wavelengths of electromagnetic radiation is considered, Antares pumps out more than 60,000 times the energy of our sun!

Red Antares is similar to but somewhat larger than another famous red star, Betelgeuse in the constellation Orion. Yet Betelgeuse appears slightly brighter than Antares in our sky. Hipparcos satellite data places Antares at about 604 light-years away, in contrast to Betelgeuse’s distance of 428 light-years, explaining why the larger star appears fainter from Earth.

Like all M-type giants and supergiants, Antares is close to the end of its lifetime. Someday soon (astronomically speaking), it will effectively run out of fuel and collapse. The resulting infall of its enormous mass – some 15-18 times the mass of our sun – will cause an immense supernova explosion, ultimately leaving a tiny neutron star or possibly a black hole. This explosion, which could be tomorrow or millions of years from now, will be spectacular as seen from Earth, but we are far enough away that there likely is no danger to our planet.

Antares in history and myth. Both the Arabic and Latin names for the star Antares mean “heart of the Scorpion.” If you see this constellation in the sky, you’ll find that Antares does indeed seem to reside at the Scorpion’s heart.

Antares is Greek for “like Mars” or “rivaling Mars.” Antares is sometimes said to be the “anti-Mars.” All of this rivalry (or equivalency … for what is rivalry, after all?) stems from the colors of Mars and Antares. Both are red in color, and, for a few months every couple of years Mars is much brighter than Antares. Most of the time, though, Mars is near the same brightness or much fainter than Antares. Every couple of years, Mars passes near Antares, which was perhaps seen as taunting the star, as Mars moves rapidly through the heavens and Antares, like all stars, seems fixed to the starry firmament.

As is typical, more mythology attends the full constellation of Scorpius than the star Antares. Perhaps the most well known story of Scorpius is that the Earth goddess, Gaia, sent him to sting arrogant Orion, who had claimed his intent to kill all animals on the planet. Scorpius killed Orion, and both were placed in the sky, although in opposite sides of the heavens, positioned as if to show the Scorpion chasing the Mighty Hunter.

Interestingly, Betelgeuse in the constellation Orion is similar in appearance to Antares, although brighter. Betelgeuse is not as associated with Mars as is Antares. Although the planet passes in the vicinity of Betelgeuse every couple of years, it never gets as close as it does to Antares.

In Polynesia, Scorpius is often seen as a fishhook, with some stories describing it as the magic fishhook used by the demigod Maui to pull up land from the ocean floor that became the Hawaiian islands. According to the University of Hawaii’s Institute for Astronomy website, the Hawaiian name for Antares, Lehua-kona, seems to have little to do with the constellation. It means “southern lehua blossom.”

Antares’ position is RA:16h 29m 24s, dec: -26° 25′ 55″.

Both are red in color, and, for a few months every couple of years Mars is much brighter than Antares. Most of the time, though, Mars is near the same brightness or much fainter than Antares. Every couple of years, Mars passes near Antares, which was perhaps seen as taunting the star, as Mars moves rapidly through the heavens and Antares, like all stars, seems fixed to the starry firmament.

As is typical, more mythology attends the full constellation of Scorpius than the star Antares. Perhaps the most well known story of Scorpius is that the Earth goddess, Gaia, sent him to sting arrogant Orion, who had claimed his intent to kill all animals on the planet. Scorpius killed Orion, and both were placed in the sky, although in opposite sides of the heavens, positioned as if to show the Scorpion chasing the Mighty Hunter.

Interestingly, Betelgeuse in the constellation Orion is similar in appearance to Antares, although brighter. Betelgeuse is not as associated with Mars as is Antares. Although the planet passes in the vicinity of Betelgeuse every couple of years, it never gets as close as it does to Antares.

In Polynesia, Scorpius is often seen as a fishhook, with some stories describing it as the magic fishhook used by the demigod Maui to pull up land from the ocean floor that became the Hawaiian islands. According to the University of Hawaii’s Institute for Astronomy website, the Hawaiian name for Antares, Lehua-kona, seems to have little to do with the constellation. It means “southern lehua blossom.”

Antares’ position is RA:16h 29m 24s, dec: -26° 25′ 55″.

Throwback Thursday: The Physics Of Fireworks (Synopsis) [Starts With A Bang]

“Celebrate the independence of your nation by blowing up a small part of it.” –Summer of 4 ft. 2; The Simpsons

There are few things as closely associated with American independence as our willingness and eagerness to celebrate with fiery explosions. I refer, of course, to the unique spectacle of fireworks, first developed nearly a millennium ago halfway across the world.

But these displays don’t happen by themselves; there’s an intricate art and science required to deliver the shows we all expect. So what’s the science behind fireworks?
