Here at The Naked Scientists HQ, it's marine month! Throughout four programmes in July, come dip your toes into all things aquatic as we work our way down to the bottom of the deepest ocean. From building superior sandcastles to the Mexican clam that's invading Europe, we kick things off with a trip to the beach. Plus, how scientists have created the brightest light on Earth, new news on fake news and a drumming bird, nicknamed Ringo.
