When asteroids attack, dinosaurs lose. Though there are still competing theories as to why we lost awesome animals like Tyrannosaurus rex and Velociraptors, many scientists look to a long-ago asteroid impact to explain the wipeout.

A study published in Earth and Planetary Science Letters adds a new wrinkle to the asteroid assumption by suggesting that the dinos may have had to contend with not one, but two deadly balls of flying space rock. Titled "Morphology and population of binary asteroid impact craters," the study was lead by Katarina Miljkovic from the Institute of Earth Physics in Paris.

If you look out into space around Earth, you'll find that about 15 percent of asteroids are binary, meaning they're traveling in pairs. However, only 2 to 4 percent of craters on Earth have been labeled as binary impacts. Miljkovic believes this number is under-reported and that many binary asteroids have been overlooked because their craters overlap.… Read more

How well do you know the geography of the moon? This weekend brings a great chance for you to brush up on your lunar knowledge.

Starry Night Education points out that when the moon rises each night this weekend, we Earthlings can view a great angle of these jumbo lunar craters: Plato, Archimedes, Copernicus, Ptolemaeus, and Clavius. … Read more

It's a surprisingly dangerous world out there in the trees. Sparrows sing, flit about, and fight like they're auditioning for a role on "Game of Thrones." Male swamp sparrows will even take their battles to the death. Before they get that far, though, there's a whole lot of wing-waving going on to mark their territory and signal their aggression.

Duke University biologist Rindy Anderson wanted to learn more about how these birds communicate with each other, so she and engineering undergraduate student David Piech built a cyborg robo-battle-sparrow of doom.

The Frankensparrow consisted of a miniature computer and robotics gear stuffed into the body of a dead sparrow. This allowed the researchers to control the wings. They took the Frankenstein sparrow to a breeding ground, played swamp sparrow invasion songs, and made it wave its wings at other males, the sparrow equivalent of flipping them the bird.… Read more

Some see, not to mention make, art in unusual places. And so it is with U.K.-based musician Sivu, who is letting viewers peer inside his mind while he sings -- literally.

Reportedly inspired by the work being done on children born with cleft lips and palates at St. Bartholomew's Hospital in London, Sivu lay in an MRI scanner for almost three hours and sang his new single, "Better Man Than He," repeatedly. The resulting music video is an edit of that footage, relying on nothing but the relatively new real-time medical imaging technique often used … Read more

When the Country Fire Authority in Victoria, Australia, noticed that its firefighters were showing signs of heat stress even when their ear thermometer probes were reading normal temperatures, they decided it was time to find a better gauge in the hopes of preventing heat-related illnesses.

So they tested a smart pill on 50 firefighters evacuating 20 people from a burning medical center, and have already used the readings to change firefighter work patterns, including how long they're exposed to blazes, according to the Australian Associated Press.… Read more

Worried about all those security cameras tracking your every move? Try rocking one of these visors and enjoy anonymity once again.

At least that's what Isao Echizen from Japan's National Institute of Informatics is trying to achieve with the Privacy Visor (PDF).

Developed with Seiichi Gohshi of Kogakuin University, the visor has a near-infrared light source that messes up cameras but doesn't affect the wearer's vision, according to the institute. … Read more

As if pulling a storyline from the movie "Jurassic Park," a Harvard University professor says it would be possible to clone the long-extinct Neanderthal. One little hitch is that he'd need a woman willing to carry the offspring.

Contrary to a flurry of headlines following his interview with German magazine Der Spiegel, however, Harvard molecular geneticist George Church is not currently taking applications from would-be surrogate moms.

"The real story here is how these stories have percolated and changed in different ways," Church, a well-respected genetics professor at Harvard Medical School, told the Boston Herald following a slew of recent impossible-to-ignore headlines such as "I can create Neanderthal baby, I just need willing woman," and, from the Daily Mail, "Wanted: 'Adventurous woman' to give birth to Neanderthal man - Harvard professor seeks mother for cloned cave baby." … Read more

You're onboard the Millennium Falcon. You give the command to jump to lightspeed. The stars outside turn into long streaks of light and you're off. It's one of the most memorable images of sci-fi space travel ever created. It's also likely to be pretty far from reality, according to a study by a group of students from the U.K.'s University of Leicester.

The study, titled "Relativistic Optics Strikes Back," was published in the University of Leicester's Journal of Physics Special Topics. You can indulge in all the delicious physics equations in the abstract.

The physics students started by imagining that the Millennium Falcon has accidentally wandered into our solar system, on a direct course for our sun. If it then engaged in near-lightspeed travel, the stars around it wouldn't appear to stretch out. Instead, it would look more like a disc of light.… Read more

LAS VEGAS--What happens when you put a couple of SpaceX engineers together with some old-school batteries? You get a new-school approach to battery power. Tetherboard calls the Tethercell "the world's first app-enabled smart battery." Wait, don't fall asleep, this is actually pretty cool.

A Tethercell battery is the size of a regular AA battery, but it holds an AAA battery inside its little case. It also holds a Bluetooth chip inside the case. Think of it as a battery turducken. This means you can use your smartphone to control the battery. Oh the power. You can turn off little Billy's toy guitar when you want to take a nap. You can disable your spouse's remote control when you can't stand another second of mindless channel-flipping. You can even set hours when a device can be used.… Read more
