Someday You Could Save Your Files With Nothing But a Sticky Note

Today's slim, svelte computers look great. You, on the other hand, look like a total yutz fumbling around to plug a thumb drive into a USB port that's somehow perpetually upside down. What if saving your data was as easy as slapping a sticky note on your screen? That's what a design team proposes with this highly theoretical design for paper-thin, sticky memory cards.

Designers Aditi Singh and Parang Anand theorize that a single layer of graphene sandwiched between two flexible protective layers could provide up to 32GB of storage space. A sticky edge would carry data from an optical data transfer surface conveniently built in to the edge of your computer monitor.

Of course is completely theoretical and in no way buyable, but it's a nice dream. Graphene is a wonder material, to be sure, but graphene-based consumer products are still a long, long way off. And while the designers do an admirable job of explaining how the sticky notes themselves could (someday, possibly) work, they leave the Optical Data Transfer Surface—the engine that makes the whole process possible—completely mysterious.

The Reason We Yawn Might Actually Be To Cool Down Our Brains


)
Just like the CPU in your computer, the human brain has an optimal temperature where it runs best. But unlike a computer's CPU, there's no built-in fan to chill the brain when it starts to run hot. Which is why researchers now believe that yawning is actually the body's physiological way of keeping the brain nice and cool.

Traditionally, it was believed that yawning was how the body increased its oxygen intake when someone was sleepy, to help wake them up—but this is a more interesting conclusion. The act of yawning increases your heart rate, blood flow, and uses muscles in the face that are all connected to keeping the brain cooled. It also turns out that exhaustion and sleep deprivation can contribute to a rise in the brain's temperature, which is why we tend to yawn more often when we're tired.

But why do we yawn when others do? It's believed that that phenomenon is tied to our ability to empathize with others. Which is why it's harder to get kids below the age of five to yawn when you do, because their empathetic abilities have yet to fully develop. And it also explains why people with autism are less likely to start yawning when they watch someone else do it.

So, how many times did you 'cool your brain' while reading this post or watching that video?

New Test Predicts Alzheimer's at Least Three Years in Advance

A new blood test developed by scientists from Georgetown University in Washington DC is capable of predicting onset of Alzheimer's with 96 percent certainty three years in advance—and that figure could soon stretch to decades.

The researchers report their new test in Nature Medicine, explaining that it identifies 10 chemicals in the blood which are associated with the disease. While tests already exist to diagnose the condition, this is the first to predict its onset.

The test was developed using a group of 525 people aged 70 and over, who initially showed no signs of mental impairment. They were given cognitive tests over a five year period, and also had blood samples taken. Over the five years, 28 developed Alzheimer's—enough to identify the 10 chemicals which indicated the presence of the disease.

In subsequent trials, the presence of those chemicals in blood samples has been used to predict the onset of Alzheimer's within three years, with up to 96 percent certainty. The next step is to make the test even more sensitive—and the researchers hope that it could then be used to predict the onset of the disease 10 or 20 years in advance.

The only question then is: would you actually want to know? More here.

A Simple Digital Watch With a Stylish Handwritten Font

\When you think of a digital watch, you can probably picture the simple boxy numbers created by a traditional segmented LCD display. This Script Watch uses the same technique—an LCD display broken up into static segments that can only be turned on or off—but manages to display the time as if a talented calligrapher just penned it onto your wrist.

Created by Adrian and Jeremy Wright, the watch of course relies on the clever design of its LCD segments. The various curves, swooshes, and contours assemble into the numbers one to nine, vastly improving the font used to show the time without requiring a full pixel-based display which requires more processing and power. It will still set you back $175, but that's reasonable if you think of it as a smartwatch—or at least a watch that looks smart. More here.

Making Plastic, Fertilizer, and Superglue Out of Thin Air

What to do with an environment-wrecking molecule like carbon dioxide? The gas behind global warming and ocean acidification enjoys a pretty rough reputation these days, but scientists have been working on ingenious ways to put carbon dioxide to good use. A little electricity, it turns out, can transform the waste gas into raw material for making plastic bottles, antifreeze, fuel, and more.

Take Liquid Light, profiled in this New Scientist piece. The New Jersey start-up recently showed off a prototype of its carbon dioxide converter, a coffee table-sized "layer cake of steel and plastic." Their first product will be ethylene glycol, a molecule that is used to make plastic bottles and antifreeze. The company says it has created catalysts that can convert carbon dioxide to over 60 different molecules.

It works like this: a lot of useful molecules, such as methanol (wood alcohol), isopropanol (rubbing alcohol), are butonal (a fuel) are just some combination of carbon, oxygen, and hydrogen atoms. Zapping carbon dioxide with electricity in the presence of different metal catalysts and other gases turns it into a whole range of carbon-based molecules. It's just plain chemistry.

While industrial products won't be that big of a carbon sink (relative to the massive amounts we're emitting into the atmosphere, at least), using carbon dioxide represents a 180ยบ turn from thinking about the gas purely as a waste. We might imagine carbon credits of the future to include an entirely new line of plastic products—from pens to clothing to water bottles—all made of carbon sequestered out of thin air. More here.

If You Want To Be Immune To Tasers Just Wear Carbon Fiber Clothing

It's no Iron Man suit, but if you've got a knack for civil disobedience and often find yourself on the business end of a Taser, the folks at Hackaday discovered that carbon fiber clothing can actually let you shrug off those electric shocks.

To be more specific, they cut open the lining of a sports coat and lined it with endless strips of iron-on no-sew hem tape and carbon fiber tape so that the resulting jacket still had lots of flexibility. The carbon fiber conducts electricity much better than human skin, and since the strips were placed close enough to let the juice flow between them, they were able to dissipate the charge without shocking down the dapper-looking target.
This approach could actually be used to line and protect everything from pants, to shirts, to gloves, and if you had the budget, you could probably stitch together entire wardrobes from carbon fiber. Just skip the part where you harden it with epoxy and you should be able to move fine. Not that you would use this power in any situation from which you'd need to run quickly, of course.

Pizza Hut and Chaotic Moon Studios Interactive Concept Table



Behold the future, my friends. It isn't hoverboards or laser swords or transportation hailing apps or drone deliveries, it is this: a gigantic touchscreen that lets you build your own pizza on the table that you will eat it on. Use the touchscreen to perfectly customize your order, play games while you wait and pay from your smartphone. The future looks delicious.

Yeah, I know it's a Pizza Hut and Chaotic Moons Studio concept that obviously cribs UI deets from Microsoft Surface but this silly pizza building service (an evolution of the Domino's Pizza Hut tracker if you will) is a good enough reason to eat Pizza Hut and have Microsoft Surface everywhere.

You Can Now Buy the Official Pillow-Fighting Pillow of Japan

Are you one of the All Japan Pillow Fighting Association's rapt and loyal followers? Are you tired of the more conventional sports fans sauntering around in their jerseys while you walk around swag-less? Looks like your day has finally come. As of yesterday, you can finally buyan Officially Recognized by the All Japan Pillow Fighting Association Pillow of your very own.

The pillows, produced by Makura Kabushikigaisha (which, according to Rocket News 24, literally translates to Pillow Corporation), are expressly designed to give you extra walloping power while still remaining relatively harmless to the atackee. Stuffed with "perfectly weighted crushed latex," the packing peanut-esque filling adds the necessary weight to the pummeling device while remaining elastic enough to absorb most of the hit.
Safety is, apparently, a major concern in professional pillow fighting, so the pillow is completely free of any tags or fasteners that might be cause for a bleeder. And it doesn't matter whether you find its grey and white stripes aesthetically pleasing—this pillow is all about function. Supposedly, this combination of colors makes it easier to notice as it comes in for the kill. The pillow will set you back a cool $30. More here.

You'll Never Believe All The Things Made Out Of Chicken Feathers

As a nation, the United States consumes a whopping 8 billion chickens every year, and this results in a few mountains' worth of chicken feathers in pure waste. But no more, some entrepreneurs say: chicken feathers could be the future of plastic.

It all began in 1993, according to Modern Farmer, when USDA researcher Walter Schmidt decided to turn chicken feathers into... something useful. That thing, whatever it was, would remain TBD. They fried it (which apparently tasted a lot like pork rinds). They made it into paper (which turned out textured and tissue-like).

The latest idea is plastics. Not unlike our hair and nails, chicken feathers are mostly a strong protein called keratin. The feathers can be heated, mixed with other materials, and molded into plastic. And, as we in the 21st century know, plastics can be used to make pretty much everything, from shoes to wall insulation to circuit boards to furniture. But chicken feathers could even show up in a few more unexpected places.

Like powder makeup:
For example, the Nixa, Missouri-based Featherfiber Corp. is commercializing Schmidt's group's 1998 patent on technology to separate feather fiber from the quill. Close to opening a production plant, Schmidt says they will soon produce cosmetics and car parts. "The feather fiber grinds to a powdery talc making the keratin useful in beauty products," Schmidt adds.
Or diapers:
Feathers have even been used to replace the absorptive layer in diapers that are usually made out of wood pulp, also called "fluff pulp." Swapping wood pulp out for feathers may save more than a few trees, Schmidt points out. Plus, it just works really well.
There are lots more chicken feather ideas in the works, from oil spill cleanup to hurricane-proof roofing. In fact, Schmidt, the chicken feather evangelist, likes to speculate about the day when chicken feathers become so useful that meat is a mere byproduct of feather production. More here.

Offshore Wind Farms Might Save Us From Hurricanes


In the matchup of wind turbine v. hurricane, our bets have traditionally been with the hurricane. But think about it this way: wind turbines are designed to suck energy out of wind. What if they could suck out so much energy that hurricanes like Katrina or Sandy never form in the first place—with the potentially destructive storm instead spun directly into electricity? That's the win-win situation posited in a new study from Stanford and University of Delaware researchers.

The study, published in the journal Nature Climate Change today, has been provoking scientists since it was first presented at conferences months ago. It's surprising, in part, because it inverts how we usually think about offshore wind turbines.

"Will the turbines be destroyed? That's the main question people ask," says Mark Jacobson, the study's first author. According to their model of Hurricanes Isaac, Katrina, and Sandy, though, offshore wind turbines could have dissipated the storms before their winds even got up to destructive speeds. And the turbines would have turned that wind into electricity, a benefit over other hurricane defense strategies like sea walls.

Will it work? How?

There are exactly zero operating offshore wind farms in the United States right now— northwestern Europe has most of the existing ones—and the farms in the study are unthinkably massive, up to half a million turbines. As a matter of practicality and politics, this isn't going to happen anytime soon. But if we want to dream big about energy policy and hurricane defense, then this is that dream.

And it could theoretically work, according to other scientists. "The study is highly academic and idealized," says Robert Vautard of the Climate and Environment Science Laboratory in France, although "the result is believable." It's all based on a computer model, but it's the best computer model we have.

Think about how quickly hurricanes dissipate on land, says Julie Lindquist, an atmospheric scientist at University of Colorado, Boulder. That's, in part, because the sea surface is very smooth but land is not. "You're essentially building large forests of slender trees in the water," says Lindquist. Of course, that will affect the climate during non-hurricane season, too, but that's a whole other study to do.

When it comes to natural disasters, engineers have come up with ways to withstand them, but never actually tame them. These hurricane-harnessing wind turbines offer a seductively elegant and presently impractical solution to it all. It's possible to imagine—and also question—the potential of tens of thousands of turbines spinning offshore to power and guard our homes from hurricanes. More here.

Whoa, Watch Bacteria Instantly Turn Water Into Ice


Believe it or not, making ice is more complicated than just making water really cold. One thing that helps is bacteria. Yes, bacteria! In this captivatingly magic video, it takes just a second for Pseudomonas syringae to turn a whole jar of water into ice.

How does it work? It's the same principle behind how snow forms in the atmosphere. An ice crystal needs to form around a nucleus, which can be a bit of dust, soot, pollen, or, as we've seen, bacteria. Pure water doesn't have to crystallize into ice until it's as cold as 55 F below zero. In the demo here, the water has been supercooled to about 21 F, but it only freezes over after the P. syringae is added.

Maggie Koerth-Baker, who first spotted the video for Boing Boing, explains where P. syringae's cold superpower comes from.
P. syringae gets this skill from the proteins that cover its surface membrane. The proteins basically form a physical structure that water molecules latch onto. That structure also orients the molecules in a way that prompts the formation of ice crystals. It's these proteins that really serve as the instigator of ice nucleation and they're incredibly efficient at it — far more so than dust...
Commercial snow machines use the proteins (though not the bacteria itself) to help instigate the creation of snow on ski mountains.
In its earthbound life, P. syringae causes disease in plants, so its snow-forming ability might seem bizarre. One hypothesis is that ice nucleation is really a subtle means of hacking the weather system: bacteria drifts up into the atmosphere and falls back to earth as snow and hail, traveling hundreds of miles in between.

We humans might think ourselves clever using bacteria proteins to make artificial snow for ski resorts, but the microbes have been way ahead of us.

A Simple Trick to Keep Your GoPro Footage Steady


GoPro is the bestselling camera in the world because like a good date, you can take the tough sucker anywhere. Just mount it on your surfboard/snowboard/bicycle and it'll snag back dope fisheye footage for your bragging video. Handholding a GoPro, however, yields shaky results.

The above video from professional wakeboarder and video producer MicBergsmademonstrates a simple tip to help you get better results from your GoPro: Hold the GoPro up to your face to use your body's natural stabilization to your advantage. While I've never tried this with a GoPro, it's very similar to clenching a heavy DSLR up against your body, using it as a natural tripod when you're shooting at very slow shutter speeds. It's a common photographer's trick. Of course, MicBergsma's trick isn't going to work in all situations, but it's just another tool to throw on the heap so you can get better footage from you adventures.

Can You Actually Drink Too Much Water?



We've all heard horror stories of water intoxication, where it's claimed people drink too much water and, ultimately, die. But is it really true?

Short answer: yes. But watch this ASAP Science video to find out that, in reality, it is actually very unlikely that you'll ever have to worry about it.

Scientists Turn Off Pain Using Nothing But Light

Pain is a hard problem. Sure, we can throw a little morphine at pain in the short term, but researchers continue to struggle with solutions for chronic pain. New research from Stanford's futuristic Bio-X lab looks like a light at the end of the tunnel—literally!

Put simply, a team of scientists has developed a way to turn pain on and off using light. They used a technique known as optogenetics to insert light-sensitive proteins called opsins into the nerves of lab mice. After a couple of weeks, the nerves became light-sensitive. One color of light would increase the sensation of pain; another would decrease it. This bears huge implications in a number of fields, from neuroscience to psychology, and could help millions of people who suffer from chronic pain.

So that's pretty awesome. What's even more impressive is the fact that researchers made the discovery by accident. Optogenetics is a burgeoning field pioneered by Karl Deisseroth who was a co-author of a study about the new technique published this week in Nature Biotechnology. It enables scientists to control nerves using just light. Scott Delp, whose lab made the discovery, was exploring the use of optogenetics to control muscle movement when he found that the opsins were also affecting the nerves that controlled pain. "We thought 'wow, we're getting pain neurons, that could be really important,'" Delp said in a statement.

The excitement offered by optogenetics don't stop at pain relief, of course. Just a few months ago, scientists also figured out how to control hunger using opsins and light therapy. Experts say the field could impact everything from brain disease to alcoholism. And they make it look so easy. More here.

This Perfectly Counterbalanced Supervillain Table Will Never Fall Over

When decorating their over-the-top headquarters, supervillains need to choose bold office furniture that matches their even bolder schemes to take over the world. And designer Toni Grilo delivers with this gravity-defying coffee table, which looks like it's perpetually on the verge of falling over.

But like any great supervillain, the Lithos Table is actually really hard to topple. Made from pieces of black-veined aziza marble, the table looks like it's one large piece of stone, but on the inside it's engineered to be light and incredibly stable thanks to a counterbalance system that no one ever sees.

Although pricing details aren't known yet, it's safe to assume that when the Lithos Table is available from Haymann you'll probably need a decent stash of cash to afford it. But with a couple of strategic ransoms and kidnappings, even a regular villain could probably raise enough cash in no time. More here.

Facebook Is Buying Messaging App WhatsApp for $16 Billion


Facebook just entered into an agreement to buy the hugely popular messaging app, which recently passed the milestone of 450 million active monthly users. The cost? $16 billion (more on the price below). Wow.

Wait...How Much?

According to the release, the purchase price is $4 billion in cash, $12 billion in Facebook stock, plus another $3 billion in restricted stock given to the founders and employees, which vests after four years. If you see a $19 billion number floating around out there, that's why. In other words, everyone who works for the company now has a huge incentive to stay on—and it shows that Facebook is interested in the talent that worked on the service, in addition to the platform itself.

What the heck is WhatsApp?

WhatsApp is a cross-platform messaging service that works on iOS, Android, Blackberry,Windows Phone, and yes, even Nokia's dying Symbian OS. It's basically messaging that works over your data connection or Wi-Fi instead of SMS—much like iMessage, except it works for everything. WhatsApp does multimedia, it does group chat, and it's widely used internationally. It's free for the first year, and then just $1 per year after that.

According to the Facebook release, WhatsApp has 450 million active monthly users and is adding one million users per day. That's an impressive clip.

Why Does Facebook Want WhatsApp?

Facebook has been trying to nail down messaging for some time now. There were rumors that Facebook offered Snapchat $3 billion in cash, which only happened after Facebook tried to build its own version of Snapchat. Facebook Messenger is actually a nice product that works over data internationally, much like WhatsApp. Unfortunately, people don't use it, or rather, it's not incorporated into people's lives in the way text messaging is—and that's what Facebook needs. What's more, given Facebook's huge international reach, trying to edge out competitors on that front is a really smart move.

What's Going to Change?

According to a blog post on WhatsApp's website, absolutely nothing. Here's what co-founder Jan Koum had to say on the topic:
WhatsApp will remain autonomous and operate independently. You can continue to enjoy the service for a nominal fee. You can continue to use WhatsApp no matter where in the world you are, or what smartphone you're using. And you can still count on absolutely no ads interrupting your communication. There would have been no partnership between our two companies if we had to compromise on the core principles that will always define our company, our vision and our product.
Do you use WhatsApp?

Pomegranate-Inspired Batteries Hold 10x The Juice

A team of Stanford scientists recently made a breakthrough. After years of trying to create a new generation of lithium-ion batteries that use energy-efficient silicon to hold a charge, they found the secret to the winning design in an unlikely place: pomegranates.

The problem with using silicon in batteries is two-fold. For one, the fragile material swells and breaks during charging. It also tends to react with batteries' electrolytes and gunk up the circuits. But silicon can also store up to ten times as much charge as existing rechargeable lithium-ion batteries.

To avoid the material's downfall, the Stanford scientists drew inspiration from the way that pomegranate seeds come in clusters. They decided to use silicon nanowires that are too small to break and encase them in carbon "yolk shells" that would allow for some swelling. (See diagram to the left.) The yolk shells were then arranged like pomegranate seeds so that they would conduct electricity well without exposing the silicon. The new, pomegranate-inspired geometry works wonderfully.

"While a couple of challenges remain, this design brings us closer to using silicon anodes in smaller, lighter and more powerful batteries for products like cell phones, tablets and electric cars," said Stanford professor Yi Cui in a statement. "Experiments showed our pomegranate-inspired anode operates at 97 percent capacity even after 1,000 cycles of charging and discharging, which puts it well within the desired range for commercial operation."

Can you imagine if your smartphone bettery held ten times the charge it does now? Life would be wonderful! Of course, it'll take some time for this new technology to be implemented, so don't stop carrying around your charger. Yet. More here.
