Science roundup: raccoons, sperm, and Archimedes

This month's science roundup highlights several fascinating discoveries, including the advanced problem-solving skills of raccoons, who exhibit 'information foraging' behavior. Researchers found they balance curiosity with effort when tackling puzzles. In reproductive science, a study revealed challenges for human sperm navigating in microgravity, potentially impacting fertility in space, though progesterone may offer a solution. Additionally, advanced imaging techniques have led to the rediscovery of a lost page from an Archimedes manuscript, showcasing the power of modern technology in uncovering historical scientific knowledge. The collection also touches on the physics of crepe folding and piezoelectricity.
