One of my favorite things about watching old movies is hearing how people might have spoken in eras past -- the expressions they used, their old-school smack talk. But what did the languages from thousands of years back sound like? Hollywood, as far as I know, has yet to make a movie in which characters talk in authentic proto-Austronesian.

The language nerd in me, was, therefore, excited to discover that scientists from UC Berkeley and the University of British Columbia have created a computer program to rapidly reconstruct vocabularies of ancient languages using only their modern language descendants. … Read more

In a few days, sky watchers in Eastern Europe, Asia, and Australia will get a chance to see one big rock hurtling through the heavens. One very big rock. Compared with other asteroids traveling through space, this one may seem a relative pebble -- at half the size of a football field -- but for Earth, it will make for a relatively close call.

"This is a record-setting close approach," says Don Yeomans of NASA's Near Earth Object Program at JPL. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth." … Read more

Imagine a day when it cost an arm and a leg to use the phone, especially for long-distance calls. Then imagine that buried deep within the telephone network infrastructure was a flaw -- a hole that allowed those who were aware of it, and capable of exploiting it, to make all the free calls they want.

These days, phone calls are free -- or nearly so -- and hackers put their energies into computer networks, jailbreaking iPhones, and other more modern pursuits. But back in the 1950s and 1960s, a new group of people emerged, people who were fascinated by … Read more

Antarctica isn't the friendliest place on earth. It's cold. It's snowy. It's tough on researchers and tough on their research stations. The cold continent has seen its fair share of stations abandoned as they're slowly consumed by layers of snow and ice. A new research station is looking to outlast its predecessors by crawling up above the snow when needed.

The Halley VI research station is the newest addition to the family for the British Antarctic Survey. It's known as the "first fully re-locatable research station in the world." That means it's got legs and it knows how to use them.… Read more

Some people use the left, some the right, but which side of the brain do you primarily use for language? It may seem like a trivial question, but for one thing, if you ever have to undergo any type of brain surgery, the answer can help avoid damage to speech areas.

While lab tests can provide the answer, an app that involves a few minutes of concentration works just as well, according to a study in the journal Frontiers in Psychology.

Furthermore, a version of the app for patients with schizophrenia trains them to improve their focus so that when … Read more

He's got blood flowing through him, but he sure isn't human. Meet Rex, the world's first complete "bionic man."

Rex has the face of a man; prosthetic limbs; a functional artificial blood-circulatory system; and artificial organs including a pancreas, kidney, spleen, and trachea. At 6.5-feet tall, Rex is valued at a whopping $1 million.

Created for the TV documentary series "How to Build a Bionic Man," Rex was constructed by a team of roboticists. The researchers say they wanted to test scientific boundaries and demonstrate how modern science is beginning to catch up with sci-fi in the race to replace body parts with man-made alternatives. … Read more

It may not make your list of must-have camping gear, but a new sheet that detects mercury levels in water may prove useful to those who live or work downstream from industrial and mining sites (such as gold mines and coal-fired powered plants) and want to drink the local water.

When dipped in water for five minutes, the sheet, manufactured by chemists at the University of Burgos in Spain, signals the presence of mercury by turning red -- a process that can be seen with the naked eye.

Take a picture of that sheet with a digital camera, and you can learn the specific concentration of the mercury, a metal that is liquid at room temperature and has been found to cause long-term neurological issues after accumulating in the brain.… Read more

Moths, despite munching on wool sweaters, are pretty innocuous for the most part. Scientists from the University of Tokyo decided to up the ante and put some moths in command of their very own robot vehicle.

The male silkmoths didn't have to pass driver's ed first, they just had to use their natural instincts for tracking down the female moth's sex pheromone. That's right, male moths do pretty much the same thing male humans do when they get their first car: go cruising for girls. … Read more

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
