Researchers have found artifacts from this time period, such as stone tools in the archaeological site Kanjera South in Kenya, showing the first tangible proof of ancient humans interacting with and hunting animals.This symbiotic relationship between humans and animals hardly comes as a surprise when domesticated pets like dogs and cats are commonplace in the modern world. However, the animals ...read more

The spinal cord is like a superhighway for the body’s nervous system. Partial injuries, like lane closures, let fewer brain signals through, but complete spinal cord injuries are akin to highway closures. No signals cross the injury site to the other side, paralyzing the body below the site of the injury.Today, there’s no way to restore motor function – such as the ability to walk – below the injury site. A recent study published in Science, however, shows that walking can be restored ev ...read more
