Now is the time to prepare for hurricanes

In conjunction with the start of the hurricane season in the Eastern Pacific (May 15) and Atlantic Oceans (June 1), officials with the U.S. National Oceanic and Atmospheric Administration (NOAA) are urging residents in coastal areas to develop preparedness plans.

Hurricanes are powerful storms with strong winds (74 miles per hour or greater) that develop over ocean basins. If they make landfall, they can be deadly. Not only can high winds topple trees and power lines, but storms surges can flood coastal zones and areas far inland. Storms surges often pose the greatest risk during a hurricane.

To help protect coastal residential along the eastern seaboard and Gulf coasts, NOAA officials will – for the first time – be producing storm surge watch and warning graphics during the 2015 hurricane season. These graphics will be available from the National Hurricane Center and will look similar to the picture posted below.

This year’s hurricane forecast from NOAA is calling for a below-normal season in the Atlantic with the potential for 3 to 6 hurricanes and an above-normal season in the Eastern Pacific with the potential for 7 to 12 hurricanes.

Kathryn Sullivan, NOAA Administrator, is urging coastal residents to be prepared for the upcoming hurricane season. She said:

A below-normal season doesn’t mean we’re off the hook. As we’ve seen before, below-normal seasons can still produce catastrophic impacts to communities.

There are several steps you can take to prepare for hurricane. First, pay close attention to weather forecasts during the hurricane season. Second, have an evacuation plan in place in case you need to leave your home. Third, prepare a home emergency preparedness kit—this kit should include things like non-perishable food, water, toiletries, first aid supplies, a hand-crank radio, and a flashlight. Visit Ready.gov for more good tips on what to do before, during, and after a hurricane.

Joseph Nimmich, the Deputy Adiministrator of the Federal Emergency Management Agency (FEMA), said:

It only takes one hurricane or tropical storm making landfall in your community to significantly disrupt your life. Everyone should take action now to prepare themselves and their families for hurricanes and powerful storms. Develop a family communications plan, build an emergency supply kit for your home, and take time to learn evacuation routes for your area. Knowing what to do ahead of time can literally save your life and help you bounce back stronger and faster should disaster strike in your area.

Bottom line: Hurricane season 2015 starts on May 15 in the Eastern Pacific Ocean and June 1 in the Atlantic Ocean. If you live in a coastal area, it is important to have a preparedness plan in place.

The Growth of My Digital Photography [Uncertain Principles]

Over at Wired, Rhett has a post providing mathematical proof that he takes too many photos. As is traditional, he includes homework at the end of the post, specifically:

Now it is your turn. Find the number of photos you have taken each year. Is it possible for you to detect changes in your life by significant changes in the image rate? Maybe you purchased a new phone or had a new addition to your family which resulted in an increase in images. That would be cool if you could see that in your data.

Well, I can’t really resist a challenge like that, so I went looking at my own photo collection. The problem is, though, that most of my older digital photos exist only in an off-site backup, as it were– I was running short of disk space, so I deleted the local copies, keeping backups on an online service that Kate uses. Re-downloading all those pictures just to count files would be tedious and also stupid, so I’ll do this using a proxy measure, namely the size of the folder containing each year’s photos. Since this is in response to Rhett, I’ll use Plotly to display the resulting graph:

Saved Photos (GB) vs Year-2003

As you can see, there’s a clear break point in the graph at around 2009. There’s a very good reason for that, namely that in 2009 I upgraded my camera from a Canon A93 point-and-shoot to a Canon Rebel XSi DSLR model. This brought a big jump up in the size of the files, and also an increase in the rate of picture taking, since the DSLR has a continuous shooting mode. I split the data into two series, and color-coded them by the camera type for the graph above, to make that clearer.

Lacking a local copy, I don’t have a very good way to convert this to number-of-pictures. A ballpark estimate of the file sizes for the two cameras produces results that I know are wrong– the average file size for the A93 camera is about 1.6MB, but using that suggests that I took only 530-odd photos in 2007, when I know I took over 1500 on our trip to Japan that year, so something is screwy. Maybe the Japan photos aren’t in the backup 2007 folder? In that case, though, the 2007 number would jump way up, changing the trend in that plot…

The big take-away from this, though, is that these data don’t look anywhere near as cleanly exponential as Rhett’s did. It looks much more like two different linear trends, but with a lot of noise. I did attempt to fit an exponential curve to this, but Plotly insists on giving it a negative constant offset, which is nonsensical, and I don’t care enough to crank this into SigmaPlot.

I am a little surprised that you can’t see the point where I took over as department chair (August of 2012), though, because my vague sense is that I’ve been doing much less photography since then, due to lack of time. That’s not really reflected in the data, though. I also would’ve expected 2014 to involve more pictures than 2013, what with our trip to London last year. But that’s also not in the data in any obvious way. Go figure.

This date in science: Walt Whitman’s birthday

May 31, 1819. Walt Whitman might not have approved of having his birthday listed among great dates in science. After all, he was a poet. But this quote by itself caused us to include him:

This is what you shall do; Love the earth and sun and the animals, despise riches, give alms to every one that asks, stand up for the stupid and crazy, devote your income and labor to others, hate tyrants, argue not concerning God, have patience and indulgence toward the people, take off your hat to nothing known or unknown or to any man or number of men, go freely with powerful uneducated persons and with the young and with the mothers of families, read these leaves in the open air every season of every year of your life, re-examine all you have been told at school or church or in any book, dismiss whatever insults your own soul, and your very flesh shall be a great poem and have the richest fluency not only in its words but in the silent lines of its lips and face and between the lashes of your eyes and in every motion and joint of your body.

Because don’t these ideas remind you of science? Not yet? Then how about this one?

I believe a leaf of grass is no less than the journey-work of the stars.

Poet and journalist Walt Whitman was born May 31, 1819 in West Hills, New York. He is considered to be one of America’s most influential poets, and his collection Leaves of Grass is considered a landmark in American literature.

Bottom line: Walt Whitman was born on May 31, 1819.

Students Take On Lab Design Challenge at Natick

By Tazanyia Mouton
USAG-Natick Public Affairs

More than 150 students, from 17 colleges and universities and three service academies, were on hand at the Natick Soldier Systems Center, April 13-17, as they participated in the 2015 Air Force Research Laboratory (AFRL) University and Service Academy Design Challenge.

The AFRL is a scientific research organization operated by the U.S. Air Force Materiel Command, dedicated to leading the discovery, development and integration of affordable aerospace warfighting technologies.

The laboratory, formed in 1997, has conducted numerous experiments and technical demonstrations in conjunction with a wide range of agencies to include the Department of Defense.

The AFRL design challenge makes great efforts to deliver creative solutions to challenging problems, and presents an exciting opportunity for students to exercise their talents and contribute to the nation’s defense.

This year’s challenge asked students to design and prototype a heat stress prevention kit that could safely, rapidly and effectively remove undesired heat away from body exteriors during special operations in hot and humid environments.

In hot environments, it is often difficult for the warfighter to wear heavy protective equipment so, the challenge also called for the kit to be rapidly deployable, self contained, and portable.

In September, students were given their mission. They had seven months to develop their ideas and create their prototypes.

The prototypes were tested in the U.S. Army Natick Soldier Research, Development and Engineering Center’s Doriot Climatic Chambers. This one-of-a-kind facility can reproduce environmental conditions that occur anywhere in the world, producing tropic wind with temperatures as high as 165 degrees, and arctic wind with temperatures as low as minus 70 degrees.

The chambers can also simulate rain up to four inches per hour and wind up to 40 miles per hour.

Through these extreme conditions, testing of physical properties of military equipment, as well as testing of physiology and adaptations of human subjects, can be performed here.

Josh Osborne, an aerospace engineer and AFRL design competition program manager, said the challenge is unique because it can present a solution to a real-world need for Air Force Special Operations.

“The overall purpose is to get a system [or] an idea together to solve the problem,” Osborne said. “At the same time, grow the future engineers that are ready to graduate and get them interested.”

Osborne said that the students also had to consider the dimensions of the system.

“When a special operations person takes something with them, they have to think, ‘Would I leave a (meal, ready-to-eat) behind to take this?’ So it has to be important enough for them to bring it to begin with, so weight and size is a big thing,” Osborne said.

After several months of working on their innovations, the challengers tested their prototypes in the chambers. Test subjects donned the students’ prototypes and walked on a treadmill for one hour at an approximate pace of three miles per hour with temperatures nearing 100 degrees Fahrenheit with 40-percent relative humidity.

Osborne said throughout the test, subjects’ heart rates and skin temperatures were monitored.

Cadet Ioannis Wallingford, a senior at the U.S. Military Academy at West Point, New York, said he is proud of the work his team has done.

“It feels great; it’s something that actually touches me pretty deep,” Wallingford said.

Wallingford said that during cadet basic training, a classmate of his died due to a heat-related incident.

“I chose this capstone because this is something that would have decreased the risk for an incident like that to happen,” Wallingford said.

Wallingford described his teams’ prototype as sophisticated but also simple.

“Our system uses a passive system combined with an active system because we realized our passive system alone would not produce the cooling capacity required,” Wallingford said. “It creates a synergistic effect between the two.”

The winner of the university challenge was Michigan Technological University, followed by second place, Auburn University, and third place Utah State University.

The winning university team of the AFRL challenge was not only awarded a symbolic “Wright Brothers” trophy, but the potential for a $100,000 grant to further develop their innovative idea.

The service academy winner of this year’s challenge was the team from the United States Military Academy at West Point.

The service academies were in a separate competition among themselves, where they had a chance to win bragging rights for the next year, as well as a trophy of their own.

Students also “win” by experiencing solutions to real-world problems, while getting an opportunity to contribute to products that could potentially help save the lives of our nation’s warfighters.

LightSail phones home after 8-day silence

The Planetary Society’s LightSail spacecraft went silent after two days of communications, falling victim to a suspected software glitch following a successful launch into orbit aboard an Atlas V rocket on May 20, 2015. Now, as expected, LightSail has phoned home. Jason Davis, who is covering the mission for the Planetary Society, wrote at his blog on May 30, 2015:

At 5:21 p.m. EDT (21:21 UTC), an automated radio chirp was received and decoded at the spacecraft’s Cal Poly San Luis Obispo ground station. Another came in eight minutes later at 5:29 p.m. The real-time clock on board the spacecraft, which does not reset after a software reboot, read 908,125 seconds—approximately ten-and-a-half days since LightSail’s May 20 launch.

The LightSail team will soon determine when to attempt deployment of the spacecraft’s thin, lightweight reflective sails. LightSail is a solar sailing spacecraft test mission and precursor to a 2016 mission. The satellite is about the size of a loaf of bread and consists of four identical triangular Mylar solar sails, attached to four 4-meter booms. When fully deployed, its square sail is designed to be pushed upon by radiation pressure from our sun. In full-scale, future light sail missions, steady pressure from the sun’s radiation would at first move the craft slowly, but eventually accelerate up to very fast speeds. The Planetary Society hopes solar sails will someday be used to propel spacecraft to the outer reaches of our solar system and beyond.

Bill Nye (The Science Guy), CEO at The Planetary Society, issued the following statement:

Our LightSail called home! It’s alive! Our LightSail spacecraft has rebooted itself, just as our engineers predicted. Everyone is delighted. We were ready for three more weeks of anxiety. In this meantime, the team has coded a software patch ready to upload. After we are confident in the data packets regarding our orbit, we will make decisions about uploading the patch and deploying our sails — and we’ll make those decisions very soon.

LightSail’s exact position is not yet clear, complicating two-way communication. Jason Davis wrote:

The ten ULTRASat spacecraft [which launched together with LightSail on May 20, aboard the Atlas V] have drifted into two groups.

But when the second signal came in eight minutes later, only the trailing group appeared to be close enough.

The primary goal of this test flight is to practice the procedure for sail deployment.

LightSail’s second flight, scheduled for 2016, will mark the first controlled, Earth-orbit solar sail flight. The plan there is that LightSail will ride along with the first operational launch of SpaceX’s Falcon Heavy rocket.

This isn’t the first-ever test of solar sail technology. Japan’s Ikaros solar sail was tested in 2010, and NASA’s Nanosail-D spacecraft orbited in 2011.

Bottom line: Two days after its launch aboard an Atlas V on May 20, 2015, the Planetary Society’s LightSail test satellite fell silent. It has now re-booted and is back in communications with Earth. The LightSail team will soon determine when to attempt deployment of the spacecraft’s sails.

The Planetary Society’s LightSail spacecraft went silent after two days of communications, falling victim to a suspected software glitch following a successful launch into orbit aboard an Atlas V rocket on May 20, 2015. Now, as expected, LightSail has phoned home. Jason Davis, who is covering the mission for the Planetary Society, wrote at his blog on May 30, 2015:

At 5:21 p.m. EDT (21:21 UTC), an automated radio chirp was received and decoded at the spacecraft’s Cal Poly San Luis Obispo ground station. Another came in eight minutes later at 5:29 p.m. The real-time clock on board the spacecraft, which does not reset after a software reboot, read 908,125 seconds—approximately ten-and-a-half days since LightSail’s May 20 launch.

The LightSail team will soon determine when to attempt deployment of the spacecraft’s thin, lightweight reflective sails. LightSail is a solar sailing spacecraft test mission and precursor to a 2016 mission. The satellite is about the size of a loaf of bread and consists of four identical triangular Mylar solar sails, attached to four 4-meter booms. When fully deployed, its square sail is designed to be pushed upon by radiation pressure from our sun. In full-scale, future light sail missions, steady pressure from the sun’s radiation would at first move the craft slowly, but eventually accelerate up to very fast speeds. The Planetary Society hopes solar sails will someday be used to propel spacecraft to the outer reaches of our solar system and beyond.

Bill Nye (The Science Guy), CEO at The Planetary Society, issued the following statement:

Our LightSail called home! It’s alive! Our LightSail spacecraft has rebooted itself, just as our engineers predicted. Everyone is delighted. We were ready for three more weeks of anxiety. In this meantime, the team has coded a software patch ready to upload. After we are confident in the data packets regarding our orbit, we will make decisions about uploading the patch and deploying our sails — and we’ll make those decisions very soon.

How do you sell death? The tangled world of illicit tobacco

illicit tobacco

Tobacco companies make more profit every year than Coca Cola, McDonald’s, Starbucks, Google, and Disney combined – a staggering £30 billion.

That vast amount of money is difficult to comprehend, and even more so if you think about how those profits are made: divide those billions by the 6 million tobacco-linked deaths worldwide each year, and it turns out that the tobacco industry makes about £6,000 from each death.

So how do they get away with it, and still make billions?

Clearly, it helps if you use whatever means necessary to keep people addicted to your deadly product.

So to mark this year’s World No Tobacco Day, let’s delve into the tangled history of the illicit tobacco trade, where corporate words fail to match corporate actions – and public health loses out.

World No Tobacco Day

This year’s World No Tobacco Day sets out to focus the public’s mind on this illicit trade, which has been fuelled by both criminal networks and by tobacco companies’ own leaky supply-chains. Consequently, ‘illicit’ tobacco products are both genuine cigarettes smuggled across borders to avoid tax, and counterfeit products.

Each year, sales of these products cost more than €10 billion in lost tax and customs revenue across Europe.

And given that Governments continue to use tax to reduce smoking rates, illicit trade undermines public health by making smoking cheaper and more accessible to children and vulnerable communities.

So what do the tobacco companies have to say for themselves on the matter?

An argument made of air

During the campaign for standard packs, one of the tobacco industry’s key arguments was that plain packs would make counterfeit and smuggled tobacco easier to come by. As we said at the time, this argument is deeply flawed, for two reasons:

Firstly, because of the clear evidence that these companies themselves play a role in illegal trade.

Secondly, as we’ll see below, because of the very nature of international tobacco smuggling.

In fact, there is no reliable evidence that the introduction of standardised packs – due in the UK in 2016 – will increase smuggling. When the UK’s HM Revenue & Customs (HMRC) looked in depth at the issue, they found “no evidence to suggest the introduction of standardised packaging will have a significant impact on the overall size of the illicit market or prompt a step-change in the activity of organised crime groups”.

But as well as using tobacco smuggling and illicit trade as a red herring to try to interfere with measures like standard packs, it grates to hear tobacco companies say that legal cigarettes represent a ‘safer’ option.

Let’s be clear: there is no such thing as a safe cigarette – legally manufactured or illicit – with ‘legitimate’ cigarettes containing around 70 cancer causing chemicals.

A history of mischief

So let’s look at the smuggling trade – and how the industry has been found out.

Each year some 400 billion cigarettes are illegally smuggled across international borders, making it the most widely smuggled legal product.

In 2001, the European Commission, along with 10 EU Member States filed legal action against three of the largest tobacco companies, Philip Morris International (PMI), R.J. Reynolds Tobacco Co and Japan Tobacco International (JTI), for:

‘…an ongoing global scheme to smuggle cigarettes, launder the proceeds of narcotics trafficking, obstruct government oversight of the tobacco industry, fix prices, bribe foreign public officials, and conduct illegal trade with terrorist groups and state sponsors of terrorism’. (Emphasis ours)

Smuggling is an age-old problem

Smuggling is an age-old problem

PMI and JTI settled their cases in 2004 and 2007 respectively. But in August 2014, the courts upheld a decision which will allow the EU to pursue a case against R.J. Reynolds relating to the company’s alleged involvement in a criminal money-laundering and cigarette smuggling scheme.

And there’s more. In the UK in June 2013, the National Audit Office reported that HMRC had also kept a watch on manufacturers’ ‘oversupply’, i.e. producing or importing far too much tobacco in one area, making smuggling to another much easier (we blogged about it at the time).

In some instances, the HMRC estimated that the total supply of some brands of rolling tobacco to some countries exceeded demand by 240 per cent in 2011.

Since this report, HMRC hit British American Tobacco with a £650,000 fine in November 2014 for oversupplying cigarettes to Belgium which has lower tobacco taxes than the UK.

Fox guarding the hen house

The agreements following the European Commission’s legal action included obligations on several companies to make large payments.

PMI alone agreed to pay £674 million over 12 years – but it was also ordered to control the future smuggling of its cigarettes through a range of measures.

Frustratingly, however, it was left to the company itself to put these measures into practice. Given its track record, it’s hard to believe that it was put in charge of monitoring its own illicit trade.

Andy Rowell, research fellow at the Tobacco Control Research Group at the University of Bath, is not convinced at all. ”The tobacco companies have a history of complicity in smuggling. But we know that leopards do not change their spots,” he told us.

“The companies are spending millions trying to con people that they are the victims of smuggling rather than the villains,” he says.

The 12 year agreement is now coming to an end – but the European Commission is now discussing its ‘renewal’ with Phillip Morris.

This is incredibly worrying.  There’s a fundamental conflict here, considering that the international community recognises the threat the industry poses to public health policy.

Now 180 parties have signed up to an international treaty to help reduce smoking rates and deal with the tobacco industry. Within this treaty – the Framework Convention on Tobacco Control (the FCTC treaty) – there’s a specific section worth noting. Known as Article 5.3, it’s designed to keep these companies at arm’s length when it comes to decisions about people’s well being.

Article 5.3 states that governments should engage with tobacco companies:

 ‘only when and to the extent strictly necessary to enable them to effectively regulate the tobacco industry and tobacco products’.

But is it really ‘strictly necessary’ for the EU to engage with PMI over illicit trade? And when it does, what does it say? Over the last 10 years there has been a worrying lack of transparency.

What needs to be done

We already have the blueprint for tackling illicit trade. The World Health Organisation’s Protocol to Eliminate Trade in Illicit Tobacco Products (ITP) outlines the introduction of a tracking and tracing system for tobacco products. But the protocol is useless without action – all 180 parties to the FCTC treaty should sign and ratify this protocol.

And we need to make sure the ‘track and trace’ system is one that will work, NOT one run by industry itself – something Rowell says is their preferred end-game, “which would be very much letting the foxes take over the hen house.”

It’s vital that this system – and all future initiatives to tackle the illicit trade – are completely independent of tobacco industry involvement, and that we learn from the past.

Tobacco products – which have no safe level of use – kill the population equivalent to Scotland every year. The industry’s involvement in the illicit trade demonstrates why we must raise the drawbridge, and not give them the key.

Moon, Saturn, star Antares on May 31

Tonight – May 31, 2015 – be sure to enjoy the picturesque pairing of the bright waxing gibbous moon and the golden planet Saturn above the ruddy star Antares. Saturn is at its best now, having passed its 2015 opposition – when Earth flew between Saturn and the sun – on May 22-23.

In the bright moonlight, you might have difficulty distinguishing the colors of Saturn and Antares. But if you have binoculars, they can help you to make out the colors of these celestial gems. Saturn is golden, and Antares is reddish.

Have a telescope – even a modest backyard one? Dust it off and try your luck viewing Saturn’s majestic rings. In your telescope, the rings should be visible tonight, despite the drenching moonlight.

Watch for the threesome – the moon, Saturn and Antares – to go westward across the sky throughout the night. They’ll be highest up for around midnight, and will sit low in the southwest at dawn June 1.

Are you an early riser? Look in the southeast sky in the predawn/dawn sky for the moon, Saturn and Antares.

Are you an early riser? Look in the southeast sky in the predawn sky for the moon, Saturn and Antares.

Saturn will stay in the vicinity of Antares, the brightest star in the constellation Scorpius the Scorpion, for the rest of this year.

Antares depicts the Scorpion’s beating Heart. Beating? Yes, because from our northerly latitudes we tend to look at Antares low in the south, and the atmosphere causes it to scintillate.

Thus Antares, a red star, is know to twinkle fiercely. Antares is a red supergiant star, whose volume is a few hundred million times greater than that of our sun. If Antares replaced the sun in our solar system, its circumference would extend all the way into the asteroid belt in between the orbits of Mars and Jupiter.

Saturn is near Antares – Scorpius’ brightest star – but Saturn actually resides in front of the constellation Libra the Scales, quite close to the Libra-Scorpius border. Saturn will remain within Libra until October 2015, at which time the ringed planet will pass in front of the constellation Scorpius.

When the moon drops out of the early evening sky in the second week of June 2015, it will be much easier to see Libra’s two brightest stars, Zubenelgenubi and Zubenschamali. These moderately-bright stars are easily visible in a dark country sky. In fact, if you have binoculars, you can see that Zubenelgenubi is actually a double star – two stars in one (even on a moonlit night).

At one time, Scorpius was a much larger constellation, and included what is now known as the constellation Libra. Before Libra became its own constellation, the stars Zubenelgenubi and Zubeneschamali depicted the Scorpion’s Claws.

The names of these two stars pay tribute to the glory days of Scorpius as a super constellation. Zubenelgenubi is an Arabic term meaning “the Southern Claw of the Scorpion” whereas Zubeneschamali is Arabic for “the Northern Claw of the Scorpion.”

Bottom line: Use the moon to locate the ring planet planet Saturn and the red supergiant star Antares on the night of May 31, 2015. After that, look for Saturn to light up the constellation Libra, and to guide you to the Scorpion’s ancient Claw stars, for months to come!
