They wiggle, though they don’t do much else. That’s what we’ve long thought about the auricular muscles — the useless ear muscles that once helped our ancient ancestors hear. But recent research in Frontiers in Neuroscience reveals that these muscles are still trying hard to help us, activating during difficult listening situations.“There are three large muscles [that] connect the auricle [the outer ear] to the skull and scalp,” said Andreas Schröer, a study author and a neuroscient ...read more

Humans are social creatures. Many of us enjoy spending time with friends and family doing social activities, like going out to dinner, attending sporting events, and participating in book clubs. According to the Centers for Disease Control and Prevention (CDC), being social offers a myriad of health benefits, including emotional regulation, reduced stress and anxiety, better sleep, and a reduced risk of heart disease and stroke. And now, thanks to a new study published in Alzheimer's & Deme ...read more

Pain relief without addiction has been a pharmaceutical goal long before the opioid crisis. A newly approved medicine appears to have achieved that.The U.S. Food and Drug Administration (FDA) approved Journavx to treat short-term pain. The drug, which was developed by Vertex Pharmaceuticals in Boston and tested as a pain treatment following surgeries, targets the nerves near an injury site instead of in the brain.“It works in a way that is different than previous medications,” says Paul Negu ...read more

About seven years from now, in 2032, an asteroid orbiting the Sun will fly so close to Earth that it has a little over 1 percent chance of impact. The asteroid, named 2024 YR4, stands out as the only near-Earth asteroid out of the over 37,000 currently recognized to have an impact probability above 1 percent. Scientists calculated this probability after the asteroid was reported on December 27, 2024 at a telescope in Chile belonging to the Asteroid Terrestrial-impact Last Alert System (ATLAS), ...read more

At long last, the Eaton and Palisades wildfires in Los Angeles are almost fully contained.It has been more than three weeks since the blazes erupted on Jan. 7, 2025, and now, as I'm writing this on Friday, Jan. 31, they are finally just a percent or two from full containment, according to the California Department of Forestry and Fire Protection. Driven by hurricane force winds, the fires quickly roared through a desiccated landscape. Together they've scorched 37,469 acres — an area more than ...read more

Although we often associate dogs as man’s best friend, new information suggests that sheep may have been by our side all along.A team of geneticists and zooarchaeologists in Europe have analyzed 188 genomes from a selection of domestic and wild sheep bones from across the past 12,000 years. In these samples, they discovered that sheep have existed alongside humans during many important transitional phases in our history. “This research demonstrates how the relationship between humans and sh ...read more

One of the unsung foundations of modern civilization is the ability to detect oscillating fields, be they radio waves, visible light, x-rays, magnetic fields, gravitational waves among the countless varieties. It is no exaggeration to say that our 21st century lives depend on this ability. So it should come as no surprise that physicists would like to do this with ever increasing accuracy and sensitivity. In recent years, they have learned how to use the strange properties of quantum particles t ...read more

Researchers have discovered mysterious new microbes that colonize the microscopic world inside our mouths and digestive tracts.These obelisks, as they've been named, are minuscule bits of ribonucleic acid (RNA) that serve an unknown function, even though their presence could be widespread in the microbiome, according to a recent study published recently in Cell. Obelisks and ViroidsIt’s unclear exactly what obelisks are — even the researchers who discovered them still know very little. Ivan ...read more

Fish caught by methods that can also entangle whales, dolphins, and seals will be banned from U.S. import, starting Jan. 1, 2026, according to a recent agreement.Conservation groups earlier this month made a deal with the U.S. government to stop importing seafood that doesn’t meet marine mammal protection standards. U.S. fishers must also follow similar standards in domestic waters.The agreement is intended to minimize bycatch — the accidental entanglement of mammals fishers weren’t intend ...read more

There’s a lot in our lives today that traces back to ancient Greece and the other cultures of the Aegean: our politics and philosophy, our art and architecture, and, apparently, our lead pollution. That’s according to a study of sediment cores from in and around the Aegean Sea, which found the earliest-known evidence of human-caused contamination from lead, and tied it to the area’s inhabitants around 5,200 years ago. Published in Communications Earth & Environment, the study also iden ...read more
