World’s Oldest Fossils Aren’t Actually Fossils, New Research Suggests World’s Oldest Fossils Aren’t Actually Fossils, New Research Suggests

Two years ago, researchers from the University of Wollongong in Australia shook the science world by claiming to have discovered 3.7 billion-year-old fossils in a rock formation in Greenland, a finding that pushed back the origin of life on Earth by 200 million years. New research is now casting doubt on this…

NASA Astronaut Shares Harrowing New Details About Failed Soyuz Launch NASA Astronaut Shares Harrowing New Details About Failed Soyuz Launch

Nick Hague is back in the United States following last week’s aborted launch of a Soyuz-FG rocket. The NASA astronaut has now described the incident to the Associated Press, explaining what happened after the Russian-built capsule flew away from the failing rocket at speeds reaching 4,000 miles per hour.

Here’s Where the Post-Apocalyptic Water Wars Will Be Fought Here’s Where the Post-Apocalyptic Water Wars Will Be Fought

A United Nations report published last week said we have about a decade to get climate change under control, which—let’s be honest—isn’t likely to happen. So break out your goalie masks and harpoon guns, a Mad Max future awaits! Now, as new research points out, we even know where on Earth the inevitable water wars are…

Using ground-penetrating radar, archaeologists in Norway have discovered an ancient Viking ship buried just 20 inches beneath the surface of a farmer’s field. The 66-foot-long ship, deliberately buried during a funeral ritual, appears surprisingly intact—and it could contain the skeletal remains of a high-ranking…

This Hilarious Optical Illusion for Birds Could Save Your Life This Hilarious Optical Illusion for Birds Could Save Your Life

Birds and planes are a bad combination, but it’s not so easy to shoo our avian friends away from airport runways. Thankfully, scientists from France have stumbled upon an ingenious solution to the problem—an optical illusion that appears to scare the crap out of large predatory birds.

After Soyuz Failure, Space Is Now Weirdly Inaccessible to Astronauts After Soyuz Failure, Space Is Now Weirdly Inaccessible to Astronauts

All crewed launches have been suspended by Russia’s space agency following yesterday’s Soyuz rocket failure. That’s a problem, because much of the world relies on Russian rockets to get both cargo and people into space. Consequently, we’re now facing the very real possibility of having an uncrewed International Space…

Google’s AI Bots Invent Ridiculous New Legs to Scamper Through Obstacle Courses Google’s AI Bots Invent Ridiculous New Legs to Scamper Through Obstacle Courses

Using a technique called reinforcement learning, a researcher at Google Brain has shown that virtual robots can redesign their body parts to help them navigate challenging obstacle courses—even if the solutions they come up with are completely bizarre.

Hungry Dinosaurs May Be the Reason Humans Need Sunscreen Hungry Dinosaurs May Be the Reason Humans Need Sunscreen

What do blind cavefish, dinosaurs, and sunburnt humans have in common? A lot more than you may realize, according to a thought-provoking new study.

Hidden Secrets of Pulsars Revealed by Trippy Computer Simulations

A new computer model is revealing the unseen and often bizarre behaviors of particles streaming around rapidly spinning neutron stars, also known as pulsars.

Newly Discovered Volcanic ‘Lost World’ Is a Haven for Marine Life Newly Discovered Volcanic ‘Lost World’ Is a Haven for Marine Life

Australian scientists have discovered a previously unknown chain of volcanic seamounts near Tasmania. The area appears to be brimming with marine life, including a surprising number of whales who may be using the undersea volcanoes as a navigational tool.

Intense Heat From Ancient Vesuvius Eruption Caused Victims' Skulls to Explode Intense Heat From Ancient Vesuvius Eruption Caused Victims' Skulls to Explode

During the Mount Vesuvius eruption of 79 AD, clouds of superheated gas enveloped the ancient city of Pompeii and its surrounding areas, instantly vaporizing bodily fluids and soft tissues, according to new research. Sounds grim, but this mode of death was actually a blessing in disguise, given the alternatives.

Oh Crap, It Looks Like Europa’s Surface Is Covered With Gigantic Shards of Ice Oh Crap, It Looks Like Europa’s Surface Is Covered With Gigantic Shards of Ice

Jupiter’s moon Europa, with its subsurface ocean, may have what it takes to foster alien life. A mission to this icy moon is on the wishlist of many astronomers, but new research suggests it won’t be easy to land spacecraft there: Its surface seems to be littered with icy spikes, the tallest of which measure five…

Ukraine Found the Perfect Use for the Radioactive Land of Chernobyl Ukraine Found the Perfect Use for the Radioactive Land of Chernobyl

Chernobyl is producing power again—though not the kind that triggered a nuclear meltdown 32 years ago. Ukraine is now turning to solar power, and in the process, making good use of land that won’t be habitable to humans for another 24,000 years.

Neanderthals Survived in Ice Age Europe Thanks to Effective Healthcare Neanderthals Survived in Ice Age Europe Thanks to Effective Healthcare

Neanderthals cared for their sick and wounded, and new research suggests this well-documented behavior was more than just a cultural phenomenon or an expression of compassion—it really did help them survive.

Scathing Report Accuses the Pentagon of Developing an Agricultural Bioweapon Scathing Report Accuses the Pentagon of Developing an Agricultural Bioweapon

A new technology in which insects are used to genetically modify crops could be converted into a dangerous, and possibly illegal, bioweapon, alleges a Science Policy Forum report released today. Naturally, the organization leading the research says it’s doing nothing of the sort.

Archaeologists Find Oldest Example of Nutmeg-Spiced Food, Just in Time for Fall Archaeologists Find Oldest Example of Nutmeg-Spiced Food, Just in Time for Fall

Mmmm, nutmeg. It’s the spice that adds a certain something to pumpkin pies, custards, and hot cups of coffee. We love our nutmeg to an embarrassing degree, but as a recent archaeological discovery shows, its origins date back to a very different time—and far longer ago than we realized.

New Hubble Observations Boost Evidence for Elusive Exomoon New Hubble Observations Boost Evidence for Elusive Exomoon

Astronomers have confirmed thousands of planets outside our Solar System, but not a single exomoon. New research is bolstering the case for a suspected exomoon first detected last year, but scientists say the evidence is still not definitive.
