Mega Asteroid to Buzz Earth on Wednesday

Here's one less thing to worry about. A giant asteroid is hurtling toward Earth, but the folks at NASA say there is no chance it could hit us. The space rock the size of the Rock of Gibraltar, per AFP, or six NFL football fields, per CNN, will make a...

New Database Gives Tree Scientists an Important First

Tree lovers, take note: A new database called GlobalTreeSearch has for the first time provided a tally of all the world's tree species. The answer: 60,065. Scientists from Botanic Gardens Conservation International in the UK spent two years compiling the database, relying on information from 500 published sources and...

We Suck Horseshoe Crabs' Blood, Chuck Them in Sea

The horseshoe crab has been around since prehistoric days, but some experts are now worried the biomedical industry is bleeding them dry—literally. In her story for Popular Mechanics, Caren Chesler explores how retrieving the blue blood of the marine invertebrate has become a lucrative and essential industry, thanks to...

Montana Fossil Reveals Ancient Sea Creature

A fossil found by a Montana elk hunter nearly seven years ago has led to the discovery of a new species of prehistoric sea creature that lived about 70 million years ago in an inland sea that flowed east of the Rockies, the AP reports. The new elasmosaur species is...

Widow Can Sue Over NASA's Brutal Sting Operation on Her

A 75-year-old widow in tough financial straits reached out to NASA about selling a speck of moon rock her late husband had given her. Joann Davis then became the target of a sting operation at a Denny's that a federal appeals court suggested Thursday was outrageous overkill. The lead agent...

NASA Finds Food Source for Possible Extraterrestrial Life

Scientists have found a potential food source for microbes on one of Saturn's tiny moons—and that could dramatically increase the chance of finding life beyond Earth, CBC reports. In a research paper published Thursday in Science, NASA reveals its Cassini spacecraft discovered molecular hydrogen in the plumes of vapor...

You Are Probably Tying Your Shoes Incorrectly

For such an age-old problem, it's gotten surprisingly little scientific study. But now physicists at Berkeley think they've figured out why the knots of our shoelaces come untied, reports the BBC. Through slow-motion video, they found that it's a complex combination of stomping (your foot hitting the ground) and swinging...

Search Is On for Platypus Killer

Wildlife officials are calling it "a despicable act of cruelty to one of Australia's most loved animals." Over the last five weeks, three platypuses have been killed and dumped in a botanical garden in New South Wales, despite the fact that the animal is protected across the country, the Guardian...

After the Battle, Army Ants Leave No Soldier Behind

A new study provides the first evidence that ants rescue members of their own colony post-battle even when those ants aren't in imminent danger, reports the Guardian. The observation came about when biologist Erik Frank was watching army ants march out to battle termites in highly patterned formation—"like three...

Jupiter's Great Red Spot Has Some Company

It looks like Jupiter's famous Great Red Spot has some company. Astronomers recently discovered a second spot located high in Jupiter's atmosphere, according to a study published Tuesday in Geophysical Research Letters. According to a press release, astronomers are calling this new spot the "Great Cold Spot." Ars Technica reports...

Scientists Halt Growth of Colon, Stomach Cancers

Australian researchers have discovered a "revolutionary" new way to stop the growth of colon and stomach cancers, which could lead to a new cancer-fighting drug within three years. Matthias Ernst at the Olivia Newton-John Cancer Research Institute explains that white blood cells called macrophages help to heal wounds and remove...

Evidence of Deepest Life on Earth Found Near Mariana Trench

A team of researchers may have discovered evidence of the deepest life on Earth (and we're not talking college freshmen taking their first philosophy class). According to a study published Monday in Proceedings of the National Academy of Sciences, there may be microbes living up to six miles under the...

Student Discovers 14,000-Year-Old Village in Canada

We may have been wrong about how the first people arrived in North America. The widely accepted narrative, as explained by Smithsonian Magazine, is that humans walked across a land bridge between Siberia and Alaska 13,000 years ago. But lately some have begun to suspect early humans actually arrived...

Arctic Ocean Doing Its Best Atlantic Ocean Impression

The "Atlantification" of the Arctic Ocean is underway. And no, that doesn't mean we're about to get the polar bear version of Outkast, but rather that the Arctic Ocean is rapidly becoming more like the Atlantic Ocean, according to new research published Thursday. The Arctic Ocean has historically been separated...

Sorry, Cannibals: Humans Just Aren't That Nutritious

A human heart might seem like a hefty chunk of meat, but its 650 calories would hardly fill up a hungry cannibal living in Paleolithic times. It's a finding that is forcing researchers to rethink why cannibalism was practiced in that period if not as a last resort to fend...

Apes May Be Able to 'Read Minds'

Now even the great apes are getting in on debunking "fake news"—or, to be more specific, fake beliefs. German researchers have found that the primates can tell when a human is wrong about something, and can even help to remedy the situation, which in this case was assisting a...

University Held Ancient Ice. Then the Freezer Broke

It's about the worst thing imaginable for researchers studying ancient ice collected from the Arctic: a freezer failure. But that's exactly what happened at the University of Alberta in Canada, reports the CBC. School officials say they lost about 13% of their ice core samples—part of the Canadian Ice...

Patrol Tasked With Saving Ships Issues Iceberg Warning

An unusually large swarm of icebergs has drifted into North Atlantic shipping lanes over the past week, forcing vessels to slow to a crawl or take massive detours. Experts tell the AP that unusually strong counter-clockwise winds are drawing the icebergs south, with the US Coast Guard's International Ice Patrol...

Geologists Find Evidence of a Real Brexit

"Without this dramatic breaching Britain would still be a part of Europe," says Sanjeev Gupta—and no, he's not talking about Brexit. In what he dubs "Brexit 1.0—the Brexit nobody voted for," the Imperial College London researcher reveals two massive floods were responsible for physically separating Britain from...

Cassini Mission to Saturn Will End in Death, Discovery

Two decades after putting Earth in its rear-view mirror, the Cassini spacecraft is preparing to wrap up its mission to Saturn—and that means plunging to its death in the planet's atmosphere, according to a press release. Cassini has been orbiting Saturn since 2004, sending back information on the planet...
