Futurama Writer Created And Proved A Brand New Math Theorem Just For 1 Episode

We all knew the writing staff of Futurama was brainy, but this is something else. To work out the ridiculous brain switching plot line from last night's hilarious episode, writer Ken Keeler (who also just happens to have a PhD in mathematics) ended up writing and proving an entirely new theorem. This is probably the most impressive bit of side work from a TV writer since a writer ofDesperate Housewives discovered a new species or the staff of Full House developed a vaccine for a specific...

The moon is shrinking, say scientists

"Astronomers have declared that the moon is shrinking after spotting wrinkles all over the lunar surface. The tell-tale contraction marks were discovered by US scientists who examined thousands of photographs of the moon's surface taken by a Nasa orbiter.

Some of the wrinkles are several miles long and rise tens of metres above the dusty terrain. Researchers believe they arise from the moon decreasing in size by around 200 metres across its diameter. The moon's mean diameter is generally...

How to create a 'super password'

"Say goodbye to those wimpy, eight-letter passwords. The 12-character era of online security is upon us, according to a report published this week by the Georgia Institute of Technology. The researchers used clusters of graphics cards to crack eight-character passwords in less than two hours. But when the researchers applied that same processing power to 12-character passwords, they found it would take 17,134 years to make them snap.

"The length of your password in some cases can dictate the v...

The Secret Histories of Those @#$%ing Computer Symbols

They are road signs for your daily rituals-the instantly recognized symbols and icons you press, click, and ogle countless times a day when you interact with your computer. But how much do you know about their origins?

Head over to PopSci's gallery to find out the origin of various symbols (Thanks @XxLadyClaireXx)

The secrets of the ads that 'stalk' you

Imagine walking into a shoe shop in the high street, picking up and looking at a few pairs of shoes, before putting them down and leaving the store. Then imagine checking out a few other shops before popping into a newsagent, where you start flicking through a newspaper. As you do this, a display appears with the exact same shoes that you were interested in half an hour earlier, along with a deal attempting to lure you back to make a purchase.

That experience is pretty much analogous to...

Age Confirmed for 'Eve,' Mother of All Humans: 200,000 years

A maternal ancestor to all living humans called mitochondrial Eve likely lived about 200,000 years ago, at roughly the same time anatomically modern humans are believed to have emerged, a new review study confirms.

The results are based on analyses of mitochondrial DNA. Found in the energy-producing centers of cells, mitochondrial DNA is only passed down the maternal line, and can be traced back to one woman.

However, this doesn't mean she was the first modern woman, rather it indicates that...

'Immortal' Trees Can't Escape Aging

"With immortality comes immobility.

Because some quaking aspen trees can reproduce by copying themselves, some people have wondered whether they might live forever, at least theoretically. But even if that's possible, they're still not immune from the ravages of time.

As aspen clones grow older, a slow buildup of genetic mutations impairs their pollen production. After a few tens of thousands of years, they won't produce any pollen at all.

When that happens, trees will still be able to sprout...

Study reveals how old age is linked to the breakdown of brain function

It's unavoidable: breakdowns in brain connections slow down our physical response times as we age, a new study suggests.

This slower reactivity is associated with an age-related breakdown in the corpus callosum, a part of the brain that acts as a dam during one-sided motor activities to prevent unwanted connectivity, or cross-talk, between the two halves of the brain, said Rachael Seidler, associate professor in the University of Michigan School of Kinesiology and Department of Psychology...

The Mystery of the missing plastic

We're referring to the great patch of plastic in the North Atlantic Gyre. You might have read the stories in DISCOVER and elsewhere about the more famous Great Pacific Garbage Patch, a Texas-sized soup of tiny plastic pieces in the middle of that ocean. Circulating ocean currents create these gyres in several places around the world, and ocean-borne plastic gets trapped. The Woods Hole paper is the result of a two-decade study of the Atlantic patch that produced a surprising result: The...

7 ways to get the best sleep ever

"You've done all the obvious stuff — cut out late-night caffeine, made sure your bedroom is dark and cozy, avoided scary movies or struggling with your to-do list right before bed. So why are you still tossing and turning? "Certain habits you're unaware of could be sabotaging your sleep," says Kristen L. Knutson, Ph.D., assistant professor and sleep specialist at the University of Chicago's Department of Medicine. And, as you may know, lack of shut-eye doesn't just leave you foggy the next...
