Frustrated College Professors Launch Their Own Sex Ed MOOC 

Anyone who’s been paying attention knows that high school sex education in the United States is an unholy mess. And as a result, an alarming number of students enter college with little knowledge about how their bodies work in terms of reproductive health.

A team of Northwestern University professors led by Teresa Woodruff is addressing the problem with a MOOC. The four-week course, Introduction to Reproduction, went live earlier this semester. It won’t teach you new sexual positions or how to manage intimate relationships, but it will provide a basic background in reproductive anatomy, sexual biology, fertility and infertility, contraception, and sexually transmitted diseases.

The Secret WWII Club That Healed Burned Pilots and Revolutionized Plastic Surgery

The Secret WWII Club That Healed Burned Pilots and Revolutionized Plastic Surgery

One of the most exclusive clubs in Great Britain is not full of hereditary peers and socialites, but instead counts former pilots and servicemen as its chief members. It’s called the Guinea Pig Club and membership dues are steep.

In order to join the Guinea Pig Club you had to have at least two reconstructive surgeries at Queen Victoria Cottage Hospital in East Grinstead, in the UK, by pioneering plastic surgeon Archibald McIndoe back in the 1940s. By the end of World War II there were 649 members, mostly from Great Britain, but also from Canada, Australia, New Zealand and the Czech Republic.

Before WWII, severe burns were rare and mostly due to household accidents. But the war changed that. Flying dangerous planes like the Spitfires and Hurricanes that were prone to accidents, full of highly flammable fuel that would spill over the pilots and crew, resulted in many otherwise healthy young men with disfiguring burns all over their bodies.

McIndoe, a native New Zealander, pioneered many of the treatment techniques still used today to treat severe burns. But he also recognized that to treat the trauma on the outside, you also have to treat the trauma on the inside. Thus the Guinea Pig Club was born.

Plastic surgery at the time was pretty crude. Even something as simple as how to best heal burns before reconstructive surgery could be attempted was a matter of trial and error. The prevailing wisdom at the time called for a special chemical coating usually applied to minor burns. It would form a protective layer to allow the burns to heal. But it proved disastrous for treating severe burns over large areas. The coating would dry out the skin, cause additional scarring, and was incredibly painful to remove. After trying the coating with little success, McIndoe observed that the burns of patients who had crashed into water would heal the fastest. So he started using saline baths for the burns instead to encourage healing.

When it came to reconstructing lips, noses and whole patches of skin on faces, more drastic measures were needed. A large sheet of skin taken from an unburned area like the thigh will not survive transplantation. McIndoe would carefully leave the skin flap attached at one end, roll it into a tube, stitch it up so there would be no infection, and attach it to another site closer to where he ultimately wanted it, like the arm. Once it had healed and started to draw its blood supply from the arm, he would detach it from the thigh and attach it from the arm to the face, where after it had healed, he could use it to reconstruct features. Patients had to walk around with their faces connected to their shoulders or arms by skin tubes that looked like little elephant trunks — but it worked. Large patches of skin survived and could be used to form new features.

Club member Bill Foxley endured 29 operations to rebuild his face. When his plane crashed he managed to make it out unharmed, but he ran back to the burning plane try to save the wireless operator who was still trapped inside. In his efforts to free him from the plane, Foxley was badly burned. (The wireless operator did not survive.)

One eye was destroyed, along with the skin, muscle and cartilage of his face up to his eyebrows; the cornea of the other eye was badly scarred. Foxley was never able to smile again because of the injuries. But that did not stop him from marrying one of his nurses at the hospital in 1947, or having a career after the war at the Central Electricity Generating Board. He developed a reputation for being hard on contractors when he would inspect their work by intensely studying it from a few inches away. The contractors never realized it was because he couldn’t see it otherwise.

Another patient, Sandy Saunders, was a glider pilot. When his plane crashed, he suffered burns on 40% of his body. His nose and eyelids had to be rebuilt. The experience inspired him to become a doctor. He would spend his recovery time between surgeries watching McIndoe operate on other patients, and dissecting frogs in preparation for his post-war career change.

One of the most remarkable things about the Guinea Pig Club was the attitude of the doctors and nurses. They didn’t treat them like invalids in recovery. The staff took pains to create a cheerful and normal environment at the hospital, and McIndoe overlooked the often inappropriate flirtations of the lonely young men with the nurses. One nurse recalled how a patient with badly burned hands still managed to pinch her when she turned around. When she threatened to punch him in the nose if he ever tried it again, he pointed out that he didn’t actually have a nose. “I can wait,” she dryly replied.

The club members had a dark sense of humor. When the club was first formed, they selected a pilot whose fingers were badly burned as the secretary so that he couldn’t take minutes, and another pilot with badly burned legs as the treasurer so he couldn’t run away with club money.

They were all very young, mostly around twenty years old. Some were suicidal when they arrived at the hospital. They had survived when their friends had died. They thought their lives were going to be over.

So McIndoe brought in showgirls to visit them from London to convince them that they could still talk to pretty girls. He got them invited to tea at the homes of local families so they felt welcomed. He let them wear their uniforms in the hospital. He kept plenty of beer on the floors. After all, the Guinea Pigs were technically a drinking club.

It was one of the first efforts to focus on both the physical and the psychological recovery of patients. Before then, people with disfiguring injuries or disabilities were often hidden from sight. Instead of casting the burned pilots and crew as unfortunate young men with their lives cut short, McIndoe presented them as heroes to be lauded for their courage. If a play was opening or a movie premiering in town, McIndoe got his patients invited as guests of honor.

And it worked. Grinstead, where the hospital was based, became known as “the town that did not stare.” A number of the club members married women they met in the town while recuperating.

The motivation to reintegrate the members of the Guinea Pig Club into society was not entirely altruistic. The Royal Air Force had spent a lot of time and money training the pilots and was eager for anything that could return them to active duty. Still, it was a big change in attitude for the military, according to Emily Mayhew, historian and author of The Reconstruction of Warriors.

The Secret WWII Club That Healed Burned Pilots and Revolutionized Plastic Surgery

After the war, the former patients continued to meet for reunions. It was only in 2007, when the oldest member was 102 and the youngest 82 that they decided they were getting too old as a group to keep traveling to reunions. The Guinea Pig Club aptly demonstrates that the key to resilience is a little humor, social acceptance, and the knowledge that you are not alone.

This Microbial Animal Threw the Evolutionary Rulebook Out the Window

This Microbial Animal Threw the Evolutionary Rulebook Out the Window

We’re taught to think of evolution as a progression from simplicity to complexity. But one organism seems to have thrown the rulebook out the window: a microbial animal that offers a striking example of evolution run “backwards.”

That’d be myxozoa, a microscopic, twelve-celled parasite whose cousins include decidedly macroscopic jellyfish and corals.

“This is a remarkable case of extreme degeneration of an animal body plan,” biologist Paulyn Cartwright of the University of Kansas said in a statement. “Animals are usually defined as macroscopic multicellular organisms, and this is not that. Myxozoa absolutely redefines what we think of as animal.”

Found in both freshwater and marine habitats, Myxozoa are a diverse clan of nearly 2,000 microscopic parasites that infect fish and invertebrates. For a long time, scientists classified them as protists, a sort of catch-all group of microscopic critters with complex sub-cellular structure that includes amoebas and paramecia. But some biologists have questioned that classification, noting that myxozoa contain an elaborate structure (called a polar capsule) that allows them to latch onto hosts. That structure is awfully reminiscent of a jellyfish stinger.

Could there be more to myxozoa than meets the eye? That suspicion was confirmed this week by a genomic analysis published in the Proceedings of the National Academies of Sciences. Turns out, myxozoa aren’t some weird group of protist loners—they’re cnidarians, the same family that includes jellies, hydra and corals. Their closest relative is Polypodium hydriforme, another cnidarian parasite with a jellyfish-like life stage.

How did myxozoas forgo their complex, mascroscopic heritage to become so small and simple? By shedding a lot of DNA. As their bodies pared down, their genomes shrunk to just 22.5 million bases—a fortieth the size of Polypodium and other jellies.

“It’s one of the smallest animal genomes ever reported,” Cartwright said. “It only has about 20 million base pairs, whereas the average Cnidarian has over 300 million.”

Perhaps unsurprisingly, myxozoas are most deficient in genes related to development, cell differentiation, and cell-t0-cell communication—all the bits of code you’d need to become a large, complex organism.

This may be the first known case of simplification from a macro to a microorganism, but Cartwright suspects evolution has performed this trick more than once. In fact, many things we call protists—a group that was cobbled together based on morphology, not genetics—may, in fact, be simple, degenerate animals. “If it can happen once in evolution, it certainly can happen again,” she said.

Now who’s writing the sci-fi novel about humanity’s microscopic descendants?

The Leonid Meteor Shower Is Tonight–Here's How to Watch It

The Leonid Meteor Shower Is Tonight–Here's How to Watch It

The Leonids are tonight! Should you watch? Oh, yes. Here’s how, when, and why to watch the meteor shower tonight—along with something strangely colorful you may be able to spot in this year’s shower.

What are the Leonids?

The Leonid Meteor Shower Is Tonight–Here's How to Watch It

The Leonids are a meteor shower formed by the debris of Comet Tempel Tuttel burning up gorgeously all around our atmosphere. Ordinarily, this is a fairly light shower, and this year is expected to be right along those lines with an expected rate of 15 meteoroids an hour.

Top image: 2009 Leonid meteor shower / Navicore / Left Image: 1966 Leonid shower / NASA

Every once in approximately 33 years, though, the Leonids turns from a meteor shower to a meteor storm where the meteors falling number in the thousands—and when that happens, even the heaviest meteor showers of the year (the Perseids, the Geminids) look almost hilariously small in comparison.

Reports of historical storms can be intense—in 1966, NASA briefly reported up to ten thousand meteors at one time. Looking back in history, other intense storms also occurred, although with less warning for sky-watchers, and the art they inspired is frankly pretty apocalyptic looking:

The last big storm was in 1999, so mark your calendars for 17 years from now, because it should be something to really see.

So how do I watch?

Timing-wise, the pre-dawn hours for this year’s show should be relatively good for meteor-spotting—but if you’re not anxious to set a 2 a.m. wake-up call, don’t fret: Moonset should be happening just after midnight, which makes it the best time to watch, in terms of having a dark canvas.

Although the meteors are expected to be fairly sparse in this year’s shower, there’s still plenty to see. If few in numbers, the Leonids are also notably bright and extremely quick-moving, at 44 miles per second—faster even than the recent Orionids shower. All of this makes this shower an excellent opportunity to look for fireballs, the showiest of all meteoroids.

How should you fireball watch? Wait for the moon to set, and then grab either a lawn chair or a blanket to lay out. It’s chilly out there, and you’re going to be out for awhile, so before you set out make sure you’ve got all your winter astronomy supplies: hat, coat, gloves, an extra blanket, a flask.

A good place to start looking is right between Leo and the Big Dipper, where you’ll find the meteor shower’s radiant, like so:

But remember, because these meteors are so quick and bright, you’re not going to want to focus too intently on any one patch of sky. Find the radiant, but then just look up at the sky as a whole. You’re going to want to see not just the start of the meteoroid, but the full streak across the sky—plus the occasional trail of meteor smoke.

And speaking of seeing unusual things...

Uh, hey, was that meteor GREEN?

Okay, so one of the interesting aspects of the Leonids meteor shower is that you often hear reports of very colorful meteors. Which color that is, though, tends to vary wildly. Some people insist on a greenish tinge, while others claim a reddish purple or orangey-yellow.

So what’s going on? Wild imaginations? A trick of the eye? No, it’s quite real, and it has to do with the inner workings of meteoroids.

The Leonid Meteor Shower Is Tonight–Here's How to Watch It

There are a lot of different variables at work in coloring a meteoroid, mainly the metals in the composition and the light around them—and that’s particularly true with the composition of the Leonids. NASA explains the reasoning behind all the different colors, and why you’re seeing them, like so:

The color of many Leonids is caused by light emitted from metal atoms from the meteoroid (blue, green, and yellow) and light emitted by atoms and molecules of the air (red). The metal atoms emit light much like in our sodium discharge lamps: sodium (Na) atoms give an orange-yellow light, iron (Fe) atoms a yellow light, magnesium (Mg) a blue-green light, ionized calcium (Ca+) atoms may add a violet hue, while molecules of atmospheric nitrogen (N2) and oxygen atoms (O) give a red light. The meteor color depends on whether the metal atom emissions or the air plasma emissions dominate.

Of course, there are colors that tend to predominate–green seems to be an oft-noted one–but really there are all sorts of things you may see when you look up tonight.

This Box Makes It Easier To Fall Asleep By Slowly Removing Blue Light From Your TV Screen

This Box Makes It Easier To Fall Asleep By Slowly Removing Blue Light From Your TV Screen

Researchers have confirmed that the blue light emitted by all of our electronic devices at night messes with our melatonin production–which in turn hinders a good night’s sleep. But with this black box connected to your TV, you can fall asleep to Netflix and still have a good night’s slumber.

The Drift–which connects between a TV and an HDMI switch or AV receiver–works by slowly and subtly removing blue spectrum light from the screen starting an hour before a user schedules their desired bedtime using a simple on-screen menu. They can also specify a wake up time, at which point the full color spectrum will be reinstated on their TV.

This Box Makes It Easier To Fall Asleep By Slowly Removing Blue Light From Your TV Screen

The Drift’s ‘Max Drift’ setting can be adjusted in ten percent increments, with 100 percent removing all of the blue spectrum light from the TV’s image. That maximizes the effectiveness of the device, and ensures your body is producing the melatonin it needs to sleep, but it also makes colors on screen look pretty awful. So individual users can specify what they prefer their ‘Max Drift’ setting to be.

Home theater snobs will almost certainly scoff at a device that dares to alter the perfectly calibrated color profile of their sets. But for the rest of us who are more concerned with getting a good night’s sleep than impressing the neighbors with our TV setups, this sounds like the next best thing to sleeping gas.

This Box Makes It Easier To Fall Asleep By Slowly Removing Blue Light From Your TV Screen

Saffron, the folks behind the Drift, are optimistic about getting the box in the hands of sleepy late-night TV addicts by Christmas. But the initial run for the $99 device will be limited to around 150 units, so if you refuse to miss those early morning infomercials despite being exhausted at work every day, you’ll want to get your order in sooner rather than later.

Brookstone and Indiegogo Are Teaming Up to Fill the World With More Novelty Gadgets

Brookstone and Indiegogo Are Teaming Up to Fill the World With More Novelty Gadgets

Brookstone, the brick-and-mortar retailer of mass-market novelty gadgets, and Indiegogo, the second-string crowdfunding platform with very few guidelines, are teaming up to try to bring the ideas of inexperienced inventors to your junk drawer.

The new partnership was announced yesterday and is aimed at putting the “best and brightest ideas from Indiegogo on the fast track to success.” In other words, Brookstone is offering to lend its decades of experience developing and marketing ancillary gadgetry to Indiegogo inventors who have no experience at all. Crowdfunding is a booming business, and a niche industry of specialized service providers have sprung up to help coach aspiring entrepreneurs through successful campaigns.

This new Indiegogo partnership is an extension of the Brookstone Launch service, which guides would-be inventors through some of the more challenging aspects of getting a product to market. The company will consult you on:

  • End-to-end design and engineering
  • Cost-effective manufacturing
  • Product packaging
  • Compliance testing
  • Product placement, signage and expert sales associates
  • Customer service and returns
  • Marketing, advertising, PR and social media
  • Wholesale and retail distribution
  • Ecommerce

If you’ve been following along, these are many of the details that cause crowdfunded projects to go to hell. It’s not enough to simply have a clever idea for a consumer product. If you don’t know what you’re doing you will fail.

And in that way, this is not the most horrible thing that has ever happened–even if the last thing I need is another crap gadget under the Christmas tree. If Brookstone can keep some of the wide-eyed optimists on Indiegogo from failing, that’s a good thing for all the generous people who naively hand their money to strangers with no strings attached.

Sorry, the Riemann Hypothesis Has Almost Certainly Not Been Solved

Sorry, the Riemann Hypothesis Has Almost Certainly Not Been Solved

Rumors are swirling that Opeyemi Enoch, a professor from the Federal University of Oye Ekiti in Nigeria, has solved the Riemann Hypothesis, a problem that has vexed mathematicians for over 150 years. Too bad it’s not true.

As reported in the BBC, The Telegraph, Yahoo! News, and many other publications, the Nigerian professor is claiming to have solved the problem, thus making him eligible for a $1 million dollar prize. Enoch has yet to make his solution public, so his claim has yet to be verified.

The problem, posited by mathematician Bernard Riemann in 1859, involves the average distribution of prime numbers (a straightforward, relatively non-mathy explanation can be found here). It’s one of seven Millennium Problems in Mathematics, a contest run by the Clay Mathematics Institute (CMI).

Enoch told the BBC that he was motivated to solve the problem after being encouraged by his students, adding that he had no financial motivation for doing so.

The university where he teaches issued this statement:

Dr Enoch first investigated and then established the claims of Riemann. He went on to consider and to correct the misconceptions that were communicated by mathematicians in the past generations, thus paving way for his solutions and proofs to be established.

He also showed how other problems of this kind can be formulated and obtained the matrix that Hilbert and Poly predicted will give these undiscovered solutions. He revealed how these solutions are applicable in cryptography, quantum information science and in quantum computers.

A spokesperson for CMI is quoted in The Telegraph as saying: “As a matter of policy, the CMI does not comment on solutions to the Millennium Problems”

Over at the Aperiodical blog, Katie Steckles and Christian Lawson-Perfect have expressed their skepticism, saying the Riemann Hypothesis has most assuredly not been solved. They write:

Unfortunately, it looks like in this case it’s not a real proof of the Riemann Hypothesis, and this post on a Nigerian discussion forum says emphatically he has not solved it. As mentioned in that post, there’s a paper on academia.edu under his name, which is actually a copy of a paper by someone called Werner Raab (retired). Raab’s website – http://ift.tt/1l3bmSs is empty, and has a single broken link to “the truth of the Riemann hypothesis”. Some digging reveals that that URL has never worked. Confusingly, Enoch seems to be gathering papers about the Riemann Hypothesis on academia.edu under his own name.

The “proof” was presented at this legitimate academic conference (yes, the URL is “computer-conference-site.com”) which does appear to have taken place – although the photos don’t seem to show the kind of turnout you’d expect for presenting a result of this magnitude. Here’s the proceedings of the conference (Enoch’s presentation is “A matrix that generates the point spectral of the Riemann Zeta function”). It also looks like the local organiser of the conference is quite a character. (What’s the deal with fuzzy logic and definitely legitimate academic proceedings?)

Steckles and Lawson-Perfect say that the Riemann Hypothesis has not been cracked, but that the method supposedly being used by Enoch is one currently being tried by more well-established researchers.
