The formulas describe the complex behavior of a liquid when it meets a boundary Since at least the 1920s, scientists have been puzzled by the turbulence that arises when a liquid hits a wall. For instance, what happens when water violently sloshes against the side of a pool or whenContinue Reading
Hamsters are only the second species known to have spread SARS-CoV-2 to humans Pet hamsters probably carried the Delta variant of SARS-CoV-2 into Hong Kong and sparked a human COVID-19 outbreak, according to a genomic analysis of viral samples from the rodents. The research confirms earlier fears that a petContinue Reading
Weather permitting, the Virtual Telescope in Italy will have live views at 1 pm. EST (1800 GMT), and you can track it on your own, too. A SpaceX Falcon 9 booster will crash into the lunar surface in March, and you can track the rogue rocket as it nears theContinue Reading
Experts are calling them hybrid Byzantine ring pommeled swords. Archaeologists in Turkey have discovered two “rare and unique” swords in a heavily fortified city from the Byzantine Empire, a new study finds. One of the swords, unearthed in a church, may have been placed there as an offering. Both ironContinue Reading
Only the largest males get to mate, so the pressure to eat and grow is extreme If you’re a male northern elephant seal, your car-sized bulk is crucial to your genetic legacy, since only a fraction of the very largest males will have access to mates. Now, scientists have foundContinue Reading
Scientists say that the new material is even more durable than real dental enamel Enamel, the tough outer covering of a tooth, is the hardest substance in the human body. It is also notoriously difficult to replicate artificially. Throughout history, dentists have repaired damaged and decayed teeth with everything fromContinue Reading
The “rolling stop” feature introduced by Tesla in October meant that cars rolled past stop signs instead of stopping, as many states require by law Tesla is recalling more than 50,000 cars in the US because the AI behind its self-driving feature acted too aggressively, rolling past stop signs ratherContinue Reading
Archaeologists don’t know why the horse was decapitated. The skeletal remains of a man buried 1,400 years ago near a headless horse have been discovered at an ancient cemetery in the town of Knittlingen in southern Germany. He likely was the horse’s owner/rider when he was alive. The man wasContinue Reading
House cat skulls have gotten significantly smaller over the last 10,000 years, and so have their brains. Thousands of years of human dependence has shrunk your cat’s brain, new research suggests. In a study published Jan. 26 in the journal Royal Society Open Science, researchers compared the cranial measurements (anContinue Reading
Hammerhead flatworms are often described outside their native range. Scientists have discovered an alien hammerhead flatworm species that looks a bit like a miniature king cobra, or perhaps an itty-bitty snake with a moustache. The researchers found the tiny creatures hunting snails in France and Italy, and they’ve named theContinue Reading
