The Brain May Actually Keep Generating New Cells Well Into Old Age

Scientists have long been divided over whether neurogenesis—a process involving the growth of new neurons—continues into adulthood. Last year, a controversial study published in the journal Nature posited that humans stop generating new cells in the learning- and memory-centered hippocampus region long before reaching adolescence. Now, research published in Nature Medicine shifts the debate back in favor of late-in-life neurogenesis: As Sharon Begley reports for STAT, the latest findings suggest humans are actually capable of producing fresh cells well into their 90s.

New “Immunobiotic” Could Treat Antibiotic-Resistant Superbugs

Our medical system is at a crisis point. Bacteria that we could once easily dispatch are out-evolving our current antibiotics, leading to the growth of “superbugs.”

Your Low-Calorie Sweetener Could Be Making You Fat

With nearly 40 percent of the world’s population now classified as obese, and increasing evidence pointing to sugar as the culprit, people are turning to foods that contain low-calorie sweeteners to give them the sweet taste they enjoy, without the risk of gaining weight. However, new research from George Washington University in the U.S. suggests that artificial sweeteners may actually increase a person’s risk of becoming obese.

Scientists Now Know Exactly How Lead Got Into Flint’s Water

For decades, the pipes that brought water to LeAnne Walters’ house did their job unnoticed and safely. But in summer 2014, that changed.

The First Human Clinical Trial of Synthetic Blood Will Begin Soon

For decades researchers have been trying to make fake blood to feed shortages, treat people with diseases like sickle cell anemia and even study diseases carried by bloodsucking mosquitoes. Now a candidate for synthetic blood will be tested in the United Kingdom in the first trial of its kind, as James Gallagher reports for BBC.
