It's well established that runaway stars and planets are a cosmic reality, but runaway galaxies? Yes, amazingly enough, those exist. Scientists have discovered at least 11 galaxies moving so quickly (up to 6 million miles per hour) that they're escaping the gravitational tug of their host clusters...

Butterflies have proven to be a surprising source of inspiration for technology, and that trend isn't about to slow down any time soon. German researchers have discovered that irregular, nanoscopic structures on the glasswing butterfly's namesake transparent wings eliminate most reflections at any...

NASA knows that it can't rely solely on astronomers and robotic rovers to find life on other worlds, so it's recruiting some help. The space agency has formed the Nexus for Exoplanet System Science (NExSS), a coalition of scientists who study astrophysics, Earth, other planets and the Sun. The gro...

Like it or not, all galaxies will eventually die. But have you wondered just how they meet their grisly ends? Researchers now have a good idea. They've studied 22 very large elliptical galaxies about 10 billion years old, and have discovered that these celestial bodies die from the inside out. The...

Scientists typically believe that dark matter, for all of its mystery, behaves in a simple way: if one clump encounters another, the two interact solely through gravity. However, researchers using both Hubble and the Very Large Telescope have published findings which suggest that there's more invo...

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...
