In Eastern Africa, the cradle of humankind is tearing apart

Long-duration spaceflight can chip away at an astronaut's health, prompting scientists to find new ways to make living in space easier on the body. The journey to outer space is incredibly dangerous, but crews must also face day-to-day hazards, such as exposure to cancer-causing radiation, microgravity and extreme isolation.

With nearly 400 years under its cork, glass is still the top choice for consumers when it comes to packaging preferences for wine, but sustainability concerns may open the way to other container types, a study by food science and economics researchers has found.

Think you're shopping intelligently for a used car? New research from the McCombs School of Business at The University of Texas at Austin suggests you might be overly influenced by the first digit on the odometer, when you're determining the car's worth.

Scientists have identified two specific types of brain cells that behave differently in people with depression, offering a clearer picture of what is happening inside the brain. By analyzing donated brain tissue with advanced genetic tools, the researchers found changes in neurons linked to mood and stress, as well as in immune-related microglia cells. These differences point to disruptions in key brain systems and reinforce that depression is rooted in biology, not just emotions.
