No, you haven't stumbled across an internet video from 1997 -- that's the output of one of the cleverest cameras you'll see in a while. Columbia University researchers have developed a self-powered camera whose pixels both record light and turn it into electricity. The trick is the use of photodio...

The Philae comet lander might be slumbering, but it can still teach you a thing or two about the nature of celestial bodies. European Space Agency researchers have compared Philae's data against the more distant Rosetta probe, and they've discovered that Comet 67P/Churyumov-Gerasimenko isn't magne...

Don't look now, but what you know about the universe's growth might have been turned on its ear. University of Arizona scientists have learned that a certain type of supernova (Ia) isn't the reliable measuring stick for universe expansion that previous data would suggest. By comparing optical and ...

Doctors dream of injecting cells with large nanoscopic cargo to treat or study illnesses. The existing approach to this is extremely slow, however. At one cell per minute, it would take ages to get a meaningful payload. That won't be a problem if UCLA scientists have their way, though -- they've d...

The quest to find proof of life beyond Earth hasn't been without its setbacks, but NASA isn't deterred. If anything, it's optimistic -- Chief Scientist Ellen Stofan now claims that there will be "definitive evidence" of extraterrestrial life within the next 10 to 20 years. Given the sheer number o...

Yes, it's back -- after a two-year upgrade program, CERN's Large Hadron Collider is once again operational. Scientists are only firing collision-free proton beams right now to test the new system, but they'll ramp up over the next few months to the point where they're smashing protons together at ...

The days of having to rely on pricey lab sensors (or carefully trained canines) to detect bad food and bombs may soon come to an end. Oregon State University researchers have developed a hybrid optical and nanotechnology sensor that's at once super-sensitive to gas, but won't weigh a ton or cost a...

It isn't quite the soft exosuit that DARPA's working on, but scientists have developed a lightweight exoskeleton that'll take some of the work out of walking. Before you get too excited though, this is less Edge of Tomorrow and more along the lines of mechanical engineering. Researchers from Carne...

Until now, quantum teleportation (that is, sending quantum data from one place to another) has required a room-filling machine. That's not going to usher in a brave new era of quantum computing, is it? However, a team of British and Japanese researchers has shrunk things down to a much more reason...

Robots typically rely on batteries to get power, but they may soon have to do little more than nibble on another material to start moving. Chinese researchers have developed simple liquid metal machines (not shown here) that zip around if they "eat" aluminum and other substances that produce elect...

As a rule, bionic hands are clunky contraptions made of motors, pneumatics and other machinery that just can't be as elegant as the real thing. Germany's Saarland University might just change that, however. Its researchers have developed an artificial hand that uses smart nitinol (nickel titanium)...

NASA's Curiosity rover isn't done finding signs that Mars once had the prime ingredients for life... not by a longshot. The explorer robot has discovered evidence of nitrates, the nitrogen compounds that are some of the key nutrients for life, in rocks at three places near its landing site. This s...

It's trivial to see mature stars in action, but baby stars are another matter. They 'only' spend 150,000 years in their earliest formative stage, and they rarely give away clues that they're around. That's what makes the above pictures so important -- scientist Emily Safron and colleagues have bec...

Use a gadget with a lithium-ion battery inside and you'll eventually learn that these power packs decay once you've cycled them enough times. But have you ever wanted to see direct evidence of why they have a limited lifespan? The Department of Energy is happy to oblige. It developed a special dev...

Hate buying some new gadget, only to wind up with a sea of packing peanuts that do little more than spill on to the floor? Don't be too quick to toss them out -- they may be the key to a new generation of lithium-ion batteries. Purdue University researchers have developed a heating process that co...

If you were an NFL player, what would you do in between games? Live the high life? Spend more time working out? The Baltimore Ravens' John Urschel does something decidedly geekier: co-author math papers. The offensive lineman recently helped publish details of a "cascadic multigrid algorithm for c...

Electric cars can do more for the environment than cut back on air pollution and fossil fuel use -- they can make sweltering summers more bearable, too. Researchers have determined that EVs create a cooling effect in urban areas, since they aren't producing heat that builds up in traffic jams. Tha...

This isn't some long lost Jackson Pollock, it's what's going on inside the mind of a fruitfly. Life really does imitate art, as this incredible collection of medical images from Wellcome Images illustrates. These spectacular shots leverage modern medicine's most advanced imaging techniques while p...

The end is nigh, Engadget readers: a triumvirate of celestial events is happening simultaneously. Okay, that might be a bit of an overstatement, but until we hit the other side of today's supermoon, spring equinox (yay!) and total solar eclipse, we just won't know. As The Wall Street Journal tells...
