An injection that blocks the activity of a protein involved in aging reverses naturally occurring cartilage loss in the knee joints of old mice, a Stanford Medicine-led study has found. The treatment also prevented the development of arthritis after knee injuries mirroring the ACL tears often experienced by athletes or recreational exercisers. An oral version of the treatment is already in clinical trials with the goal of treating age-related muscle weakness.
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
The Pecos River murals are a stunning collection of monumental, multicolored rock paintings in limestone rock shelters across southwest Texas and northern Mexico. They depict human-like figures that reach up to eight meters tall, animals such as deer and snakes, and complex abstract symbols. For years, no one really knew how old these rock art masterpieces were or how long this artistic tradition lasted.

A new study has shown for the first time that its influence on human behavior can be altered using transcranial ultrasound stimulation (TUS).
They say an elephant never forgets—and it turns out they can learn to adapt to drones. Once seen as a source of alarm, drones are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, the use of drones in elephant conservation has mostly relied on their power to disturb: elephants reliably run from them, making them a useful tool to drive elephants from croplands.
