A Harvard Team Has Finally Solved The Mystery Of How Stress Turns Hair Gray

by Franzified

Over a decade ago, in 2009, the New York Times appeared with the headline, “After 44 days in the White House, Obama’s hair is grayer.” It was a reference to a common trend of presidents’ hair turning dramatically gray during their terms in the White House.

The idea of stress turning hair gray, is often called the Marie Antoinette syndrome, which is a reference to the often-told, but most likely apocryphal, story of the ill-fated French queen’s hair, which is said to have turned white overnight after she was captured during the revolution.

While the idea of one’s hair turning white in an instant after a sudden fright is an amusing cartoonish fiction, there is a solid body of anecdotal evidence describing instances where hair rapidly turns white after months, or even weeks, of stress or trauma.
“Everyone has an anecdote to share about how stress affects their body, particularly in their skin and hair – the only tissues we can see from the outside,” explains senior author on the new study, Ya-Chieh Hsu. “We wanted to understand if this connection is true, and if so, how stress leads to changes in diverse tissues. Hair pigmentation is such an accessible and tractable system to start with – and besides, we were genuinely curious to see if stress indeed leads to hair graying.”

Sure, Why Not?: A Light That Projects An Imaginary Window On Your Wall

window-lights-1.jpg These are the REVEAL lighting systems available from Adam Frank Incorporated. Powered by halogen ($280) or LED ($320, and 1/10th of the energy consumption) bulbs, the lighting systems project an imaginary window anywhere you want one in the dark using "multi-plane analog images to create real depth of focus." Plus "air currents through the projector create organic, non-repeating movement in the background." How about that! Each light includes five different window style slides, and five different tree views for a total of 25 different combinations so you can find your perfect fake window. Of course if you're got $280 to spend on an imaginary window you've easily got the money to buy a sledgehammer, duct tape, and a roll of clear plastic sheeting to make a real window. Shoot, for that kinda money I'll make you all the windows you want. AND skylights. Keep going for several more shots and a video.

When a Man Took a Joke in a Pepsi Ad Seriously

by Miss Cellania

In 1995, Pepsi ran a promotion in which they offered merchandise for "Pepsi points." You could redeem your Pepsi points for clothing and accessories and all sorts of neat stuff, as you can see in the original ad. The prizes ran all the way up to a Harrier jet for seven million Pepsi points.

The joke is simple enough: they took the idea behind Pepsi Points and extrapolated it until it was ridiculous. Solid comedy writing. But then they seemingly didn’t do the math. Seven million sure does sound like a big number, but I don’t think the team creating the ad bothered to run the numbers and check that it was definitely big enough.

But someone else did. At the time, each AV‑8 Harrier II Jump Jet brought into action cost the United States Marine Corps over $20 million and, thankfully, there is a simple way to convert between USD and PP: Pepsi would let anyone buy additional points for 10 cents each. Now, I’m not familiar with the market for second-hand military aircraft, but a price of $700,000 on a $20 million aircraft sounds like a good investment. As it did to John Leonard, who tried to cash in on this.

Leonard did the math, and bought enough Pepsi points to get the jet. The company was caught by surprise, because they didn't do the math. Read how that turned out, and why the ad company couldn't see it coming at Literary Hub.  -via Digg

Astonishing Coin-Stacking Skills

by John Farrier

Japanese Twitter user @thumb_tani is a master of balance. He'll put coins, glasses, fruits, and other household items on top of each other and they will stay in place!

He's not cheating at all. As you can see in this video, he really can just line up items vertically.

Not surprisingly, he's also an expert juggler. I suspect that there's a lot of overlap between these two skills.

British Scientists Accidentally Discover Immune Cells That Kill Cancer

by sodiumnami

A new type of T-cell has been accidentally discovered by researchers at Cardiff University. The researchers were analysing blood from a bank in Wales when they found the new type of immune cell. The cell carries a receptor that has never been seen before, allowing the newly-discovered immune cell to latch on to most human cancers, ignoring the healthy cells. Yahoo News has more details: 

Professor Andrew Sewell, lead author on the study and an expert in T-cells from Cardiff University’s School of Medicine, said it was “highly unusual” to find a cell that had broad cancer-fighting therapies, and raised the prospect of a universal therapy.
“This was a serendipitous finding, nobody knew this cell existed,” Prof Sewell told The Telegraph.
“Our finding raises the prospect of a ‘one-size-fits-all’ cancer treatment, a single type of T-cell that could be capable of destroying many different types of cancers across the population. Previously nobody believed this could be possible.”
Asked if it meant that someone in Wales was walking around completely immune to cancer, Prof Sewell said: “Possibly. This immune cell could be quite rare, or it could be that lots of people have this receptor but for some reason it is not activated. We just don't know yet.”

Whoa: This Beautiful Star Wars CGI Short, 'Last Stand'

This is Star Wars: Last Stand, a short fan made CGI film featuring a bunch of beautifully rendered stormtroopers (in 4K too) attacking an unseen foe. In the creator's own words while I too lash out at an unseen foe and worry my coworkers. ADMIT IT -- ADMIT YOU'VE BEEN STEALING MY DREAMS:
Star Wars: The Last Stand is a dynamic, gritty and somewhat over the top full CGI depiction of battle worn storm troopers facing off against an unknown enemy. Stormtroopers are often portrayed as somewhat silly and incompetent, so I wanted to create a film to showcase troopers as skilled fighters, which is how I see them. Having the simple idea of showing Stormtroopers fighting, I knew the crux of the project would be to illustrate the battle in an interesting way. To do this I wanted to use dynamic camera angles, focusing on moments and scenes we don't usually see in Star Wars films. I worked on this piece on and off for 3 years, mostly by myself.
That's cool, but what were they fighting? Because as much as you really wanted to "showcase troopers as skilled fighters," I'm fairly certain they either caught a group of their own in friendly fire, or, perhaps even more likely, were just attacking and losing to a reflective surface. Keep going for the video while I ignore all argumentative comments about blaster colors.

Newly Sequenced Giant Squid Genome Raises as Many Questions as It Answers

by George Dvorsky on Gizmodo, shared by James Whitbrook to io9

One the most intriguing and mysterious creatures on the planet—the giant squid—has finally had its genome fully sequenced. But while the genome is helping to explain many of its distinguishing features, including its large size and big brain, we still have much to learn about this near-mythical beast.

What The?: This Crazy Visual Illusion

This is a video of a visual illusion made by optical illusion creator (and 2017 Optical Illusion Contest winner!) Gianni Sarcone and smoothly animated by Chris Said. None of the colored lines are moving and they're all the same length. Pretty wild, right? "Like Mr. Toad's Ride." Solid reference, like a healthy turd -- one you can really be proud of for eating right and not drinking too much. Thanks to Carey A, who agrees the greatest optical illusion of all time is this hologram we're living in that we call reality.

The Wild West: Driving Through Tumbleweeds Blowing Across The Road

This is a video from Richland, Washington of a car driving through a migration of tumbleweeds, which *David Attenborough voice* are presumably heading south for the winter to bone in the warmer, desert climates and return in the spring with their weedlings. "Just how dumb are you, GW?" I mean at least eight, right? There's also another video of a crew removing tumbleweeds that have completely engulfed a car. Now that's a lot of tumbling weeds! Could you imagine if you were allergic to tumbleweeds and they just kept following you everywhere? Allergies are the worst. I'd fill my pockets with the heaviest rocks I could find. "And?" Walk straight into the ocean and drown. Keep going for the videos.

Alien Abduction Ring Doorbell Glitch

This is an alleged glitch in a recording from a Ring doorbell where the video freezes and the homeowner appears to be beamed up to an alien ship. Per Youtube commenter iga ninja, "See this all the time in cameras. Not uncommon" and BibleReadingMum123, "Its because the lens is like a circle or something like that." Valuable info...from two aliens posing as Youtube commenters! Going with the Bible reading name too -- that's deep undercover. Nice Try, Zazixzan, or what your your real name is. No, I suspect this was a legit abduction. *shrug* Stranger things have happened. "Like what?" Two seasons already. And, AND -- our love. "Yeah that hasn't happened." Maybe not yet, but one sip from this love potion you'll fall head-over-heels for me. *gulping, choking* Tastes like...Nordstrom. "Jesus, was that cologne?" Let's kiss and see if it worked. Keep going for the video, but the gif is it really.

Popping A Single Popcorn Kernel With A Blowtorch And Levitating It With A Hairdryer

In but how many takes did it take news, this is a short video created by Swiss filmmakers Zita Bernet and Rafael Sommerhalder of a single popcorn kernel being dropped in front of a blowtorch where it quickly pops, launching it into the low pressure column created by a hair dryer, levitating it there. Cool, but I asked for butter. Also, how can I possibly play the penis in the popcorn trick on myself with so little popcorn? I'll know it's there all along. Keep going for the full video while I melt a stick of butter and drink it.

7 Mysterious Geological Formations That Still Baffle Scientists

by Miss Cellania

The world is full of wonders, and that includes some that even scientific research hasn't figured out yet. But curious scientists are working on them. Some are fairly inaccessible and difficult to study, some have been studied but have more than one plausible explanation, and some are just baffling. The picture here seems to show what's at the end of the rainbow, a bubblegum pink lake named Lake Hillier.

This small, saltwater lake on an island off Western Australia is only one-third of a mile long, but its bubblegum-pink color makes it especially striking. The lake was documented in 1802 by British explorer Matthew Flinders, who took a sample of its waters but failed to understand how it got its startling hue. Tourists can visit only by helicopter, though it is safe to swim in the waters.

Scientists today suspect the color is due to the presence of a pink alga, Dunaliella salina, and/or a pink bacterium, Salinibacter ruber. But unlike other pink lakes around the world, such as Lake Retba in Senegal, Lake Hillier’s color doesn’t fluctuate with temperature or sunlight—so the investigation goes on.

That explanation leaves us with another question, though- hasn't anyone taken samples from the lake? Are the helicopter pilots charging too much? Lake Hillier is only one of many geologic mysteries around the globe that scientists haven't yet solved. Read about six more of them at Mental Floss.

Behind the 'Evil Sunrise' Photograph

by Miss Cellania

You've probably seen this photograph somewhere on the internet in the last couple of weeks. It appears that the devil himself is rising from the ocean. Is it an omen? Maybe. Is it a Photoshop? No. Amateur astrophotographer Elias Chasiotis planned carefully to take images of the December 26 solar eclipse in Al Wakrah, Qatar.

The images aren’t results of pure chance and luck. Chasiotis intentionally chose a place with the open horizon where he got a perfect view of the eclipsed sun emerging from the sea. “I hoped that optical effects like inferior mirage would be visible and I was lucky enough to capture them,” he said. “The weather conditions didn’t look good in the beginning as there was a lot of haze and low clouds in the southeast.”

“I was worried that nothing would come out of the eclipse. However, when the sun finally began to rise, it looked like two separate pieces, some sort of red horns piercing the sea. It soon took the form of a crescent, with the so-called ‘Etruscan vase’ inferior mirage effect visible. Due to its shape, the phenomenon was nicknamed the ‘evil sunrise.'”

Read more about the image, and see the entire series of photographs Chasiotis took that morning at Bored Panda.

An Interactive World Map That Shows What Was Around Your Area Up To 750-Million Years Ago

earth-back-in-the-day.jpg Above: Los Angeles and New York City 280 million years ago, at the time of the first land animals. This is Ancient Earth, a map that uses data from the PALEOMAP Project to track the planet's distribution of land and water through time, all the way back to 750-million years ago. You can enter any city and choose how many million years ago you'd like to look back (or choose the time of a major events like the first shells, land plants, dinosaur extinction, first primates, hominids, etc), and it will show you what your area of the world looked like then. Obviously, it doesn't serve much practical purpose for non-paleontologists other than knowing where you can safely land a time machine, because there's nothing worse than traveling back to the Cretaceous period just to almost drown in the middle of an ocean you didn't know was going to be there when you assumed you were going to land safely in the middle of a t-rex sex party. I thought I was a goner, I really did. Thanks to Closet Nerd, who's going to see the new (now already old) Star Wars movie today. Pfft, some fan you are -- what took so long?! (I'll meet you at the theater fifteen before showtime)

Clever Shadow Billboard Advertising New 'Dracula' Television Series

To promote the just released Dracula series, this is a video of a billboard that uses precisely placed stakes and a spotlight to cast a vampire silhouette shadow. Clever. Of course those of us who thought they had a future in advertising anything but good times on restroom walls back in 2011 might recall this almost identical billboard created for Newcastle beer using stacks of real bottle caps. Also, everybody knows real vampires don't even cast shadows although they can cast reflections, I know because one goes to my gym and I caught a glimpse of his penis in the mirror. "But--" Yes, it looked like a bat. Thanks to Pavel, who agrees the best billboards of all time are those 'The McRib Is Back' ones.

Hoàng Tiến Quyết's Vivid Origami

by John Farrier

Hoàng Tiến Quyết, an artist from Vietnam, makes origami figures that seem to pop out of the limits of mere sheets of paper. He uses a technique called "wet folding", which involves moistening the paper just the right amount in order to give flexibility to it.

The results are astonishingly lifelike, especially if you watch his YouTube videos recording the creation process.

You can see more of Hoàng's work on his Instagram page in addition to his online gallery.

Now Clean The Walls And Ceiling: A Flying Roomba

This is a video created by engineer and Youtuber Peter Sripol of a robotic vacuum with three ducted fans attached so it can fly. As far as good ideas go, this might be the best and worst I've seen. Personally, I hate carrying things up and down the stairs so I just bought a separate Roomba for each floor of my house. "So one?" Well my house is only one story, but I don't actually own any Roombas because I don't believe in handing over detailed blueprints of my home to the robots so easily. Plus I believe in cleaning the old fashioned way. "Yelling at the hired help?" They have names, you know. "What are they?" Okay I always just yell peasants. Keep going for the video, but definitely skip around because ten minutes and at least eight too long.
