When your favorite band rocks out on stage, they're coordinating more than their jams and their dance moves. A new study suggests that pairs of guitarists playing the same melody simultaneously have significantly similar brain waves. The research, published today in the online journal BMC Neuroscience, is the first to measure the brain activity of more than one musician playing at the same time, and may have broader implications regarding how our brains interact when we coordinate actions with other people, like matching our walking speed with another person, playing in a band, playing sports, and dancing. The findings may also apply to social bonding behaviors, like coordinated gazes between a mother and child or between partners.

How long does it take the Earth to revolve around the sun? Did the earliest humans and dinosaurs live at the same time? What percentage of the Earth’s surface is covered with water? Think you know the answers? Well, if you’re an American adult you may be frighteningly alone.

Spitting, kicking and saving lives: all in a day's work for the lovable llama. Scientists have found that the uniquely small size of the llama's antibodies, used by the immune system to identify and counteract bacteria and viruses, could provide new and improved therapies for diseases including cancer, Alzheimer's, and diabetes.

What does it take to be a successful financial trader? Education, experience, and, according to new research at the University of Cambridge, a long ring finger.

The source of endless energy for all humankind resides just off Government Street in Burnaby, British Columbia, up the little spit of blacktop on Bonneville Place and across the parking lot from Shade-O-Matic blind manufacturers and wholesalers. The future is there, in that mostly empty office with the vomit-green walls -- and inside the brain of Michel Laberge, 47, bearded and French-Canadian.

It seemed like an ordinary day in the primordial ooze, but romance was in the methane-ammonia air. An amoeba, pseudopoding along as usual, met and was enchanted by a particularly lovely photosynthetic bacterium. He took her inside his cell membrane, but instead of digesting her as he first planned, the two fused into a single organism. The bacterium gave the amoeba the new ability to absorb energy from sunlight, and their descendants became every plant in the world.

After countless accounts of near-death experiences, dating as far back as ancient Greece, science is now taking serious steps forward to explore the nature of the phenomenon. A new project aims to determine whether the experience is a physiological event or evidence that the human consciousness is far more complicated than we ever believed.

Your phone rings. But when you pick up, you don't recognize your mother's voice on the other end. It's not amnesia, but phonagnosia -- the inability to recognize voices. If you've never heard of it, that's because it's a very rare condition that usually occurs after a stroke, as a result of lesions in the right hemisphere of the brain. This week, however, scientists at University College London (UCL) reported the first known case of a woman born with phonagnosia in the online journal Neuropsychologia.

About 190 million years ago, during the Early Jurassic Period, a vast desert larger than the Sahara covered much of what is now Utah, Wyoming, Colorado, New Mexico, Arizona, and Nevada. Given that Jurassic time was the "Age of Dinosaurs," it's not surprising that fossil evidence of the great reptiles would show up there now and then. But recently, geologists from the University of Utah uncovered an exceptional find -- a large concentration of dinosaur tracks and rare tail-drag marks.

Hormones are no longer responsible just for teenage angst and questionable food cravings; new research shows these temperamental chemicals also dictate the type of person to which you are attracted. In the first study of its kind, Drs. Ben Jones, Lisa DeBruine, and Lisa Weeling at the University of Aberdeen demonstrated that hormones play a key role in determining who you are attracted to at any given time.

Big-money competitions—like the $25-million Virgin Earth Challenge to suck carbon from the atmosphere and the $10-million Progressive Automotive X Prize to build a 100mpg car—are a great way to inspire life-changing technologies. Winning strokes the ego, of course, and eight-figure prize money is also a good lure. But what if you need some innovative ideas, only you don’t have a lot of prize money to throw around? Hand out course credit instead.

Dan Lathrop needs a bigger Earth. His old one is two feet across and 500 pounds, about 20 millionths the size of the real thing. And after four years of tests, it failed to generate a magnetic field similar to the real Earth’s, which shields us from the sun’s radiation and guides some navigation systems by pointing compasses north.

In 2005, the then-president of Harvard University said that men are better at math and science than women. (President Lawrence Summers' exact words were a bit more roundabout. While theorizing why women are underrepresented in those fields, he said "there is a different availability of aptitude at the high end.")

Turns out Summers's attitude may be to blame, according to a new study from vocational psychologists at the University of Wisconsin-Madison.

The purpose of the LHC is to get lots of protons moving very, very fast. The magnet system is the core piece of technology that makes this happen. More than 1,200 magnet sections, each weighing 10 tons, bend proton beams through vacuum pipes around the 17-mile-long underground tunnel near Geneva. Since these protons are going so fast—99.9999991 percent of the speed of light—superconducting coils of niobium and titanium must produce a magnetic field that’s about 200,000 times as strong as Earth’s to bend them.
