Spring brings warmer temperatures, fresh greenery, and the return of birdsong. Songbirds are known for performing species-specific tunes to attract mates and defend their territories. But how do birds learn these signature songs? Much like humans, it takes time and practice to master a skill.To understand the brain signals involved in birds’ intrinsic desire to learn their songs, a research team from Duke University, North Carolina, closely studied how zebra finches practice their songs until ...read more

A surprising observation from NASA’s James Webb Space Telescope (JWST) has revealed a vestige of a galaxy that peeked through the early universe’s dense fog just 330 million years after the Big Bang. The recent sighting of ultraviolet light from this distant galaxy — called JADES-GS-z13-1 — has astonished researchers, shattering prior expectations of early galaxy formation. Shortly after the Big Bang, the developing universe was clouded by a thick fog of neutral hydrogen, blocking the l ...read more

Cold plunging has become all the rage. Whether in the ocean, rivers, lakes, or your own personal cold plunge bath, enthusiasts claim that the therapy has a host of benefits, both mentally and physically, from reducing anxiety to reducing brain fog and improving focus. It’s also been touted for improving athletic performance, reducing inflammation and joint pain, improving immunity, and increasing metabolism. But are any of these benefits backed by science?Shock the Body with Cold Water Plunge ...read more

After 25 years of research, a 444-million-year-old inside-out fossil has finally been named. The fossil, which researchers at the University of Leicester have identified as a new species of multisegmented fossil, has been named Keurbos susanae, or “Sue” for short, after the lead researcher’s mom. And while its insides seem to have been well-preserved, researchers are still debating what this organism may have been. The researchers published their findings in the journal Palaeontology. � ...read more

Whether it's the near infamous Stanley cups or the Naglene, covered in national park stickers, you likely have spotted reusable water bottles almost everywhere you’ve go. College campuses, cafes, the office, and of course, the gym or on a hiking trail. People carry reusable water bottles for a variety of reasons. Perhaps they want to reduce plastic waste or microplastic intake, or maybe they are trying to stay hydrated for health reasons. Regardless of the different reasons, there is one thin ...read more

For humans, the gestation period can last forty weeks. There are cramps, morning sickness, strange food cravings, increasing discomfort, and a multitude of other effects. And the nine months of pregnancy is often just a prelude to the real drama. All this pain and suffering is for a good reason though.Scientists are still learning more about when live birth evolved, but one fossil discovery in the South China Sea revealed a 250 million-year-old creature with an embryo in its ribcage. The Dinocep ...read more

Elephants are no pushovers when it comes to walking great distances every day, and they even seem to have a knack for planning their demanding journeys. A new study puts the ingenuity of these mammals on full display, showing how they strategically choose certain routes to make their trips as efficient as possible. The study, published in the Journal of Animal Ecology, shares several key findings that demonstrate how African savanna elephants move through challenging landscapes. Being the large ...read more

Within glacial ice sheets, there are streams of ice, sometimes called ice rivers, that move much faster than the surrounding ice. If you’re having trouble imagining how ice moves inside ice, Elizabeth Thomas, a paleoclimatologist at the University at Buffalo, suggests an analogy to help visualize these icebound rivers.Since the Gulf Stream carries warm water from the tropical Atlantic Ocean up the coast of the Carolinas and then across to Europe, she explains, “the Gulf Stream is essentially ...read more

Mosquitoes are more than pests. They’re also a mortal threat, contributing to millions of cases of malaria a year. Fortunately for humans, however, a team of researchers has recently identified a medication that could curb mosquito populations, controlling their spread of malaria. Revealing their results in a paper published in Science Translational Medicine, the researchers report that the medication nitisinone makes human blood deadly to mosquitoes. “One way to stop the spread of diseases ...read more

Humanity’s search for life on Mars has taken a significant step forward with the discovery of organic molecules that resemble key building blocks of life on Earth.Since landing in 2012, NASA’s Curiosity rover has made multiple discoveries suggesting that Mars may have once had habitable conditions. Now, scientists have identified the longest organic molecules ever found on the Red Planet — offering new insights into its potential to support life.A detailed report on these findings was rece ...read more
