Microglia (immune cells) and the RANK protein are essential for triggering puberty and maintaining fertility in the brain.

Project Hail Mary by Andy Weir is one of today's best science fiction books. While much of the science and math is great, it falls a bit when it comes to evolution.

Some animals have reproductive strategies so extreme that they can lead directly to their own death. In certain species, ...

A rare Japanese ant is the only species known to lack female workers and males; all of its young develop into parasitic queens that try to take over other colonies.

A new study shows that as humpback whale populations recover from past whaling, older males are gaining a major advantage in reproduction. Early in the recovery, breeding groups were dominated by ...

Even in the ultra-dry Atacama Desert, tiny soil-dwelling nematodes are thriving in surprising diversity. Scientists found ...

Coral reefs are being hit hard by the climate crisis, and timely interventions for their survival are a top priority. The Global Coral Tech Transfer Project enables SECORE International and the ...

Other penguins that have limited diets are more threatened by changes coming from a warming ocean and the makeup of the food chain. But king penguins — which are so abundant they are considered a ...

A mouse that travelled aboard China’s Tiangong Space Station has produced 28 pups after returning to Earth, offering rare insight into how microgravity may influence mammalian reproduction.

These results are preliminary, but they could eventually improve ovarian health and fertility in women, researchers say ...

Evolutionary theory has revolutionized the way we understand humans – yet more than a century after Darwin's ideas reshaped biology, the female form of our species remains largely a mystery.

The kick-off signal for puberty begins in the brain. Specifically, in the hypothalamus, where specific neurons release a hormone that activates the hypophysis, at the base of the skull, which then ...
