A pair of chert points found alongside human skeletons in a cave in Belize may represent the first known tattooing needles ever discovered from a site linked to the ancient Maya civilization. After testing the fragmented tools on pig skins, the authors of a new study determined that the markings present on the ancient relics […]

Pet cats are a relatively new addition to the Americas. While this part of the world does have plenty of wild cats – from bobcats and jaguars to lynx and cougars – the paws of domesticated cats didn’t set foot here until European colonization around 500 years ago.  Now, researchers may have uncovered some of […]

A notoriously difficult video game appears to have a positive impact on people’s self-reported mental health, according to a new study from Aalto University. There are games that are meant for pure enjoyment, and there are games that are meant to challenge you. And then there is Dark Souls, which is meant to punish you […]

Nearly four decades after the Chernobyl disaster, farmers may be poised to return. New research shows that large parts of the once-abandoned farmland just outside the Exclusion Zone in northern Ukraine are now safe for cultivation. Amid the Chernobyl nuclear disaster in 1986, enormous quantities of harmful radionuclides were scattered into the air, contaminating the […]

Astronomers taking a close look at our nearest neighbor galaxy have made a highly unusual and model-challenging discovery; the vast majority of its satellite galaxies appear to be pointing in our direction. According to our best model of galaxy formation, the standard model, galaxies grow as smaller dwarf galaxies are pulled in by gravitational interactions, […]

A boiled egg. What could be better? A perfect pod of fats, protein, and flavor, handily packaged in a crackable shell that’s tough enough to survive boiling so that when you rip it away there’s a bouncy egg waiting inside. Only problem is, peeling boiled eggs is the worst thing ever. Flecks of calcium carbonate, […]

Genetic material from hundreds of mammoths is providing an unprecedented glimpse into their family tree and shows how these Ice Age giants emerged, migrated, and adapted to a changing world. Scientists at Stockholm University and the Centre for Palaeogenetics in Sweden analyzed the mitochondrial genomes (mitogenomes) of 34 mammoths whose DNA had never been sequenced […]

There are gems to be found in the dense forests surrounding Brazil’s Juruá River Basin. Not the kind you’ll find on a piece of jewelry, though – these ones come in the form of a brand-new, teeny tiny, and super shiny species of poison dart frog. When we say “super shiny”, we’re not kidding. These […]

The makers of a non-hormonal male contraceptive just announced a key milestone during their first human clinical trials, with the treatment demonstrating safety and efficacy at the two-year mark. The next step is Phase 2 trials, and if all goes well, developers Contraline, Inc. believe their product could come to market before the end of […]

The remarkable remains of an elite woman have been unearthed in an ancient fishing town in Peru’s Lima region. The woman’s skin, hair, and nails have all been preserved, making this an incredibly rare find in the Peruvian archaeological record. The burial was discovered at the archaeological site of Áspero, which was used by the […]

Have you ever wondered what the footprints of an ancient pangolin might have looked like? Well, you might just be about to find out, as researchers have discovered what they believe is highly likely to be the world’s first known fossilized pangolin trackway. The trackway was first found back in 2018 on a cemented dune […]

Bolivia has a “zombie” volcano on its hands. Despite being technically dead, Uturuncu in the Central Andes continues to simmer with hints of seismic activity and occasionally belches out plumes of gas. In a new study, scientists have taken a deep look at the anatomy of this undead volcano, hoping to get some insights into […]

Students in the US have participated in a competitive sperm race, in a surprisingly widely viewed $1,000,000 event. In Los Angeles on Friday, competitors gathered at LA Center Studios to watch performances by musicians, a lot of pre-match warmups, and sperm race through what the organizers are calling the “world’s smallest racetrack”. During the event, […]

The rugged, ravine-ridden terrain of China’s Guizhou province lends itself to having some monster-sized bridges, and it’s currently on the brink of unveiling one that will eclipse them all: the Huajiang Grand Canyon Bridge. This new suspension bridge rises an astonishing 625 meters (2,051 feet) from its deck to the stream below, earning it the […]

Step into the American Museum of Natural History’s Hall of Meteorites and you’ll be faced with a monster. It goes by the name Ahnighito, the largest fragment of the Innaanganeq meteorite (also known as the Cape York Meteorite) that’s so heavy, its supports go into the bedrock beneath the museum building to keep it stable. […]

Yesterday, April 28, was a big day in space launches, with not one but three different megaconstellations receiving new satellites. Eighty-seven new satellites were launched into orbit, which places the day among the top 20 busiest for putting objects into orbit – a list that includes multiple times where a rocket broke apart in space, […]

A team of astronomers poring through old astronomical data may have seen a candidate for the elusive Planet Nine – a hypothetical ninth planet in the Solar System, far beyond the orbit of Neptune. In 2016, two astronomers at Caltech presented evidence that six objects past the orbit of Neptune were bunched together in a […]

A team of geologists have conducted a survey of likely candidates to identify the oldest rock in the United States. Their work is not merely to arbitrate a battle over which state gets a chance to lure in some tourist dollars; it offers insight into the difficulties of defining a rock’s age. Most of all, […]
