    Why sing to baby? If you don’t, you’ll starve

    A new study suggests that infant-directed song evolved as a way for parents to signal to children that their needs were being met, while leaving time for other tasks, like food foraging or caring for other offspring.

    Viewing how neurons work

    A new technique for observing neural activity will allow scientists to stimulate neurons and observe their firing pattern in real time. Tracing those neural pathways can help researchers answer questions about how neural signals propagate, and could one day allow doctors to design individualized treatments for a host of disorders.
