Brain changes associated with casual marijuana use in young adults: More ‘joints’ equal more damage

Brain changes associated with casual marijuana use in young adults: More ‘joints’ equal more damage

The size and shape of two brain regions involved in emotion and motivation may differ in young adults who smoke marijuana at least once a week, according to a study published April 16 in The Journal of Neuroscience . The findings suggest that recreational marijuana use may lead to previously unidentified brain changes, and highlight the importance of research aimed at understanding the long-term effects of low to moderate marijuana use on the brain. Marijuana is the most commonly used illicit drug in the United States, with an estimated 18.9 million people reporting recent use, according to the most current analysis of the National Survey on Drug Use and Mental Health.

Motion, muscles don’t always work in lockstep, researchers find in surprising new study

Motion, muscles don’t always work in lockstep, researchers find in surprising new study

Animals “do the locomotion” every day, whether it’s walking down the hall to get some coffee or darting up a tree to avoid a predator. And until now, scientists believed the inner workings of movement were pretty much the same — the nerves send a message to the muscles and there is motion. But in a first-of-its-kind study on wild green anole lizards, biologists at the University of California, Riverside have discovered that the link between muscle function and movement is a lot more complicated than anyone realized.
