D-serine improves depressed rats' brain plasticity and memory

During depression, the brain becomes less plastic and adaptable, and thus less able to perform certain tasks, like storing memories.

The most common primary brain cancer is glioblastoma, a highly aggressive and deadly form of tumor that kills about 95 percent of its victims within five years of diagnosis.

Scientists discover that sperm do not function like olfactory cells

According to a 2003 study by German and American scientists, a component of the Lily of the Valley scent known as Bourgeonal alters the calcium balance of human sperm and attracts the sperm. The "Lily of the Valley phenomenon" - also the title of a book about smelling - was born as a result of this discovery that sperm act as swimming olfactory cells which follow a "scent trail" laid by the egg. However, a detailed explanation for the Lily of the Valley phenomenon remained illusive as neither Bourgeonal nor other scents could be identified in the female sex organ.
