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...

As much as humanity knows about Mars, the planet is still chock-full of surprises. Just ask NASA: University of Colorado researchers using its MAVEN probe have discovered phenomena in the Martian skies that you would never see on Earth. For one, there are auroras that are so energetic (their elect...

Light therapy is a safe, easy way to kill cancer and treat other diseases, but it's normally limited by its nature to illnesses that are skin-deep. Washington University researchers aren't daunted, however. They've developed a phototherapy method that brings light directly to tumor cells, no matte...

Last year, researchers claimed they found RNA from a 40,000-year-old breed of polar bear, or as it's often referred to, the Himalayan yeti (Abominable Snowman, etc.). However, another team of scientists says those hairs could've just as easily come from a species of brown bear that's native to the...

When you picture the Milky Way galaxy, you probably imagine a relatively flat disc. Well, you may have to get that image out of your head -- astrophysicists have determined that the galaxy has at least four "ripples," making it look more like a piece of corrugated cardboard than a gentle circle. T...

After a few months of slumber due to a lack of sunlight, the Philae comet lander might be close to waking up. It's receiving enough sun now that the Rosetta probe will attempt to resume contact between March 12th and 20th. If communication is successful, the next step will be to decide what resear...

Gravity can play a lot of tricks with light, and we're not just talking about black holes. Take this recent Hubble Space Telescope discovery from UC Berkeley's Patrick Kelly, for example: those four lights are actually a distant supernova magnified and split into four images by the gravitational l...

The Hubble Space Telescope spots a lot of stars, but some of them are seemingly more eager to pose for snapshots than others. Take the star you see above, for example. That's V1331 Cyg, a young stellar object that's conveniently sending a jet of gas directly toward Hubble, providing a clear (and r...

You probably know that Mars hasn't always been so barren, but have you wondered what it was like in its heyday? You almost wouldn't recognize it, according to an international team of scientists. They've used six years of atmospheric monitoring to determine that Mars had enough water to form a big...

Just how small can life get? Almost unbelievably small, if you ask a team of Berkeley Lab researchers. They've taken the first detailed electron microscope pictures of the tiniest bacteria known to date -- at a typical 0.009 cubic microns in volume, you could fit 150 of them in an already miniscul...

Metals are full of microscopic structures that define properties like strength, but it's hard to figure out how those structures work on Earth, where gravity skews their effects. An experiment aboard the International Space Station may have solved that dilemma, however. By freezing alloys in the s...
