Of the major food crops, only rice is currently able to survive flooding. Thanks to new research, that could soon change -- good news for a world in which rains are increasing in both frequency and intensity.

Ancient Splices of Biology: Tracing the Evolution of Insect Sexual Development

September 04, 2019
Sexual determination and differentiation work in myriad ways across the animal kingdom. In vertebrates, like mammals and fish, sexual determination leads to the development of either ovaries or testis. These organs then secrete hormones that go on to govern the sexual development of the rest of the organism’s body. Insects are a completely different beast.
