The Simpsons Called It: Three Eyed Fish Caught Outside a Nuclear Power Plant [Nuclear Power]
Fishermen in Córdoba, Argentina caught a three-eyed wolf fish in a reservoir fed by a local nuclear power plant, which will surely hinder the plant’s owner’s attempt to run for local office. More »
Life on Earth began in . . . Greenland!? [Biology]
Now known as one of the most inhospitable places on Earth, the giant arctic island of Greenland might actually hold the birthplace of all life on Earth. Yes, all life on Earth might well have sprang from Greenlandic mud volcanoes. More »
Women suffer from premature orgasm, too [Sex]
When we hear news about human sexual dysfunction, it often tends to revolve around men. And when female sexual dysfunction does receive attention, it’s often brought up in reference to the difficulty they face achieving sexual climax. But a new study shows that jumping the orgasmic gun is likely a problem that is faced by women and men alike—even if we don't always hear about it. More »
10 Things You Probably Didn’t Know About Dreams [Daily 10]
If we’re to believe some of the latest scientific research on sleep (or even just viral YouTube videos), the effects of dreams have likely bewildered Earth’s creatures for hundreds of millions of years. But humankind, in particular, has fostered a unique and lasting fascination with dreaming. More »
Tyrannosaurus rex was much, much bigger than we thought [Dinosaurs]
An international team of researchers has used three-dimensional laser scans to determine that Tyrannosaurus rex were likely 30% more massive that we once thought — and a whole lot hungrier. Be honest, now…how many of you woke up this morning thinking you'd hear the words "three-dimensional laser" and "Tyrannosaurus rex” used in the same sentence? More »
Scientists figure out how to switch off peanut allergy [Medical Breakthroughs]
The peanut allergy is one of the eight most common types of food allergies, and the common use of peanuts in a wide range of foods makes it particularly dangerous. But now scientists have a solution: trick your immune system. More »
Why Your Stomach Growls [Giz Explains]
Mankind has been puzzling over the rumbling in our stomachs for so long that even the ancient Greeks came up with a name for it: borborygmi. The word attempts to put the sound of the grumble to mouth. More »
Uncovering the hidden lake buried two miles beneath Antarctica [Antarctica]
There are hundreds of subglacial lakes buried deep beneath the Antarctic ice, each one completely isolated from the rest of the world for hundreds of thousands of years. And now, scientists are preparing to find out just what’s down there. More »

Samsung breakthrough could turn your window pane into a big ol’ LED
Samsung’s quest for transparency won’t end with laptops, apparently. Today, the Samsung Advanced Institute of Technology announced that its engineers have successfully created “single crystalline Gallium Nitride on amorphous glass substrates” — an achievement that would allow the manufacturer to produce jumbo-sized LEDs from normal glass, including window panes. Samsung says this scaled-up approach will allow them to lower production costs relative to most LED manufacturers, which rely on sapphire, rather than glass substrates. And, whereas most Gallium Nitride (GaN) LEDs on the market measure just two inches in size, Sammy’s technique could result in displays about 400 times larger. “In ten years, window panes will double as lighting and display screens, giving personality to buildings,” a Samsung spokesperson told the Korea Herald. Unfortunately, however, it will likely be another ten years before the technology is ready to hit the market. Until then, we’ll just have to do our late night window coding the old fashioned way.

Watch a comet smash into the Sun, followed by a massive solar explosion [Video]
What you see in this amazing video really is just a coincidence. A comet smashed into one side of the Sun just as a massive explosion ignited on the other side. Two entirely unrelated events…but they sure look awesome together. More »
The European Space Agency is officially sending a probe to the Sun [Space]
What costs a billion euros, can operate in temperatures in excess of 500 degrees celsius, and orbits the sun closer than any spacecraft in human history? More »
Fewer asteroids are menacing Earth than we thought — and we know where 90 percent of them are [Space]
NASA recently repurposed a satellite called WISE that had completed its mission with all instruments intact and quite a bit of fuel. Renaming the mission NEOWISE, the space agency gave the satellite a new job: map the entire volume of space in the vicinity of Earth’s orbit around the sun, looking for every possible rock, boulder, or planetoid that could possibly smack into our Blue Marble. What they discovered caused them to build an entirely new model of the space debris in our immediate area (see image above).
Faster-than-light neutrinos could be proof of extra dimensions [Physics]
The recent announcement that neutrinos had been observed seemingly going faster than the speed of light sent shockwaves through the physics community. But there’s one possible explanation that could keep Einstein’s relativity intact and open up a whole new cosmos. More »
This 90 Percent Successful Vaccine May Be Our Best Chance to Eradicate AIDS [Science]
Spanish researchers have completed the first human trial of a new vaccine against HIV. It has been successful in 90% of the HIV-free volunteers during phase I testing. This vaccine brings great hope to eradicate this plague forever. More »
Saltwater and sludge could give us an inexhaustible supply of energy [Energy]
Splitting water into hydrogen and oxygen is generally considered a fantastic way to get a renewable power source. The problem is how exactly you go about splitting the water. Current methods require some power input in order to kickstart the reaction, reducing its effectiveness as a sustainable power source, since power needs to flow continually in to the system. But a new technique could meld together a number of other methods and produce constant, carbon-neutral hydrogen from two things we have in abundance: fouled water and seawater. More »
Two missing genes could explain why you don’t want to exercise [Mad Science]
Laziness might not be the only reason why some people have so much trouble staying physically fit. Removing just two genes from mice completely saps them of their will to exercise, and a similar process might exist in humans. More »
