Bats Are Like Humans in One Remarkable Way

Humans were thought to be unique as a species in that we use both halves of our brains to listen. Turns out we're not as special as we thought. A type of bat also uses both hemispheres to process sound, researchers have discovered. And both humans and Parnell's mustached bats—...

Scientists Warn of Chemicals in Pizza Boxes, Carpet Care

A group of environmental scientists today issued a warning about commonly used chemicals known as PFAS. The chemicals, which go by the longer names of polyfluoroalkyl and perfluoroalkyl, are found in everything from pizza boxes to carpet treatments, reports the New York Times. "If you got a pastry with your...

Scientists Find Planet's Most Polluted Bird

The Vancouver area is home to what is thus far known to be our planet's most polluted wild bird. Researchers studying the livers of local birds of prey found that the Cooper's hawk was tainted with polybrominated diphenyl ethers, chemicals that function as flame retardants. Of the 13 hawks tested,...

Mission Over: Space Probe Slams Into Mercury

Mercury has a new crater, courtesy of NASA. As expected, the space probe Messenger crashed into the planet this afternoon after running out of fuel, reports AP. The crash at a speed of nearly 9,000mph left a hole about 52 feet wide and brought to an end an epic...

Everest Is a Little Smaller Now

Future climbers won't notice, but Mount Everest is a tiny bit shorter because of the earthquake in Nepal. Radar images show that it shrank about an inch, reports the Weather Channel. The change may have been greater had the world's tallest peak been directly above the fault line, notes Phys....

NASA Probe Will Smash Into Mercury Today

The first spacecraft ever to orbit Mercury is about to become the first spacecraft to smash into the planet. NASA says the Messenger probe will conclude its hugely successful mission when it crashes at 8,750 miles per hour into the side of the planet facing the sun today at...

Insane New Bullet Corrects Own Course in Mid-Air

An incredible superbullet dreamed up in 2008 is now a reality. The Pentagon's Defense Advanced Research Projects Agency reveals it has created a self-steering bullet that can change its own course in mid-air to hit a moving target. In a DARPA video, a sniper fires at a target that moves...

Invention May Make Air Travel Much Quieter

Does the buzzing of a plane's engines drive you bonkers? Researchers have come up with a product that could save you some grief. They've developed a thin membrane capable of blocking low-frequency noise that tends to bounce around the cabin. The honeycomb-like material typically used on a plane's floor and...

Beneath Antarctica's Blood Falls, a Clue to Mars?

The chillingly named Blood Falls is a fascinating feature of Antarctica's landscape : Interrupting the blanket of frozen white, the falls is a liquid, rusty red. (It's no coincidence that the falls looks rusty: The water gets its color from oxidized iron it carries.) And, as a researcher tells Live...

Russia Has Lost Control of Spacecraft

Russia's Mission Control has failed to stabilize a cargo ship spinning out of control in orbit, but says it has not yet given up on saving the unmanned spacecraft. The Progress M-27M was launched yesterday and was scheduled to dock at the International Space Station six hours later to deliver...

US Zoos to Let Their Elephants Die Out

Seattle's Woodland Park Zoo has kept elephants for almost a century, but the tradition has now come to an end. After a third elephant died in 2014, the zoo decided to move its two animals to a zoo in Oklahoma, where they'll have more room to roam as part of...

Don't Bother Humblebragging (It Doesn't Work)

Masking a brag with false modesty—known as a "humblebrag" in today's parlance—may seem like an effective way to boast about your achievements without seeming like, well, an egotistical jerk. But a working paper from Harvard Business School researchers finds exactly the opposite, noting that people may be better...

Church Where Pocahontas Married Rises Again

A group of archaeologists in Jamestown, Virginia, is busy doing the opposite of what one would normally expect: building something new, rather than searching for what once was. Popular Archaeology reports that an effort is underway to rebuild a potion of the church where Pocahontas wed John Rolfe in 1614...

New Rubik's Cube Record: 5.25 Seconds

Anyone who's ever stared hopelessly at a Rubik's Cube will be impressed by this: On Saturday in Pennsylvania, a teen set a new world record, solving a 3x3x3 cube in 5.25 seconds. Collin Burns was participating in the final round of a competition at Central Bucks West High School...

Biologist to New England: Slow Down, Think Frog

Northern New England's annual amphibian migration is always perilous, but critters that cross roads to breed are facing an additional challenge this year: a delayed start after the long winter. Every spring, several species of salamanders and frogs travel to vernal pools —temporary bodies of water created by melted snow—...

One-Way Streets Can Actually Be More Dangerous

Turns out one-way streets may make neighborhoods more dangerous—and in some cases, it's not because of the traffic itself. Researchers who have studied cities across the country are pointing to a possible risk of higher crime on one-way streets with two lanes, as compared to two-way streets. For one...

Why the Feds Killed 3 Million Animals Last Year

Mother Jones calls it President Obama's "kill list," but it's probably not one you'd expect. This newly released list covers the nearly 3 million animals among 319 different species that the government killed last year. Most were classified as invasive species in one regard or another, and the USDA says...

Feeling Down? Smell a Happy Person's Sweat

Scientists think they've figured out a way for people to feel happier, but applying it in real life might be a little weird: It involves getting a whiff of a happy person's armpits. It seems that we humans secrete chemicals in sweat that reflect our emotional states, and people who...

Genome Reveals Secrets of Last Mammoths

The last of the woolly mammoths in Siberia died out about 10,000 years ago, but a smaller number living on Wrangel Island, off the coast of what is now Russia, managed to stick around for another 6,000 years. Researchers set out to investigate the two groups and the...

Scientists Find Way to Distinguish Twins' DNA

Identical twins share an identical DNA profile, and when you're an investigator examining DNA evidence, that can be a problem. The cases may be rare, but they exist, legal expert Jennifer Mnookin told the New York Times last year amid a rape case involving a suspect with a twin: "There...
