Reproduction in most animal species requires breeding between two individuals. But some worms have evolved the ability to go it alone. In these species, a single individual can breed with itself to produce offspring. A new University of Maryland-led study found that gaining this ability, known as "selfing," may have caused a worm species to lose a quarter of its genome, including genes that give male sperm a competitive edge during mating.Full Story

The U.S. National Science Foundation propels the nation forward by advancing fundamental research in all fields of science and engineering. NSF supports research and people by providing facilities, instruments and funding to support their ingenuity and sustain the U.S. as a global leader in research and innovation. With a fiscal year 2020 budget of $8.3 billion, NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and institutions. Each year, NSF receives more than 40,000 competitive proposals and makes about 11,000 new awards. Those awards include support for cooperative research with industry, Arctic and Antarctic research and operations, and U.S. participation in international scientific efforts.
