In certain bird species – found mostly in Australasia or Africa – children from the previous year and from other parents help raise the newborns. A careful review of the research on this rare phenomenon […]

How baby fiddler crabs catch a wave
A new study shows how some species of fiddler crabs can compensate for changing temperatures when timing their courtship. Fiddler crabs sync up the hatching of their young with bimonthly higher tides in order to ensure they have the best chance of escaping predators. But at some times of year, cold temperatures can slow embryo […]
Towards stem cell therapy for infertile men
Researchers have created sperm cells from infertile men who could not produce healthy sperm them on their own. They did this by converting skin cells into stem cells, which then became fertile human sperm cells when transplanted into the testicles of mice. This opens up the possibility of clinical cell-based therapy that could make infertile […]
