Trail runners often use poles, but how they affect energy use and foot strength, especially after a long run, isn't well understood. A recent study looked into this by examining how using poles changes the amount of energy spent moving upward and the force exerted by the feet during uphill walking.

Teeth aren't just for chewing. They have a living part inside called pulp. As people get older, this pulp changes. It's not as lively as it used to be. There are fewer cells and blood vessels. This makes it harder for teeth to heal when they get damaged. The pulp also gets tougher. It makes more co
ALS, or Amyotrophic lateral sclerosis, is a tough disease that affects motor neurons in the brain and spinal cord. It's a challenge for scientists to understand the molecular pathways involved in ALS and other neurological diseases. In a recent study, researchers took a closer look at two types of
Scientists have been using a powerful new tool to fight cancer. Now, they are testing it on a different kind of battle: rheumatoid arthritis (RA). This therapy, called CAR-T cell treatment, gives immune cells superpowers to fight diseases. In RA, the body's defense system turns against itself, causi
