NASA's Artemis missions: Moon-bound rock stars, historic crew, and new spacesuit prototype unveiled.

NASA has announced the four astronauts who will lead the first crewed moon mission in over 50 years, including the first woman and person of color to be assigned to a lunar mission. Scientists have discovered that long-term memories take root in an area of the brain that hasn't typically been associated with memory processing, which could help researchers studying Alzheimer's disease. Astronomers are excited by the discovery of a rocky Earth-size exoplanet with a magnetic field, which could potentially support life. Researchers have recorded the dwarf reed snake, which deploys a gravity-defying cartwheel when threatened by predators, a behavior not formally observed in any other species of snake or reptile.
