The election season in particular, there’s been a focus on abortions in the third trimester of pregnancy. S...

890: How Aging Water Systems Are Pushing Sewage Into U.S. Homes 28.10.2024

Walter Byrd remembers the first time sewage came bubbling out of his toilet like it was yesterday. “It was just pumping up through there,” Byrd says. “One of the bathrooms was so full of waste, at least 4 inches high in there.

888: How Do Animals Understand Death? 24.10.2024

Throughout history, humans have given a lot of thought to death. We’ve grappled with our mortality, created elaborate burial rituals, and contemplated how best to mourn the loss of a loved one. But what about other animals? How do they understand death? Scientists have begun looking at this question more closely in the last two decades. For example, chimpanzees have a wide variety of responses to...

887: MRIs Show How The Brain Changes During Pregnancy 23.10.2024

Pregnancy is a hugely transformative experience, both in how it can change someone’s day-to-day life, and how it affects the body .

881: What Makes ‘SuperAgers’ Stay Healthy For So Long? 15.10.2024

A common worry among older adults is how their brains and bodies might decline as they age. A small but fortunate group will live past their 95th birthdays, while staying cognitively sharp and free of major health complications. They’re called “SuperAgers.” Researchers are working to figure out some of the genetic factors behind SuperAgers’ longevity—and how that knowledge might help the rest of t...

880: Asheville Was Never A ‘Climate Haven.’ Nowhere Is. 14.10.2024

For years, Asheville, North Carolina, has been billed as a “climate haven,” a place safe from the touch of climate change-exacerbated disasters.
