Mar. 8, 2022 Novel research on the life history of fruit fly sperm demonstrates molecular continuity between the male and female reproductive ...
May 13, 2021 Scientists help protect sharks by developing aquarium breeding programs that pair up individuals in ways that increase genetic diversity. In a new study, scientists undertook the largest-ever effort ...
May 17, 2021 Sperm are generally viewed as having just one action in reproduction -- to fertilize the female's egg - but studies are overturning that ...
Mar. 31, 2022 Forget sending bull semen out for complicated laboratory tests to learn whether the agricultural animal is virile. Scientists have developed a faster, easier microfluidics ...
Oct. 31, 2023 The BioRescue project develops and pioneers advanced assisted reproduction technologies (aART) for conservation in the face of the imminent extinction of most rhino species and subspecies. In a new ...
June 10, 2021 It is generally agreed that sperms 'swim' by beating or rotating their soft tails. However, a research team has discovered that ray sperms move by rotating both the tail and the head. The ...
Mar. 14, 2024 After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo, a new study finds. The work ...
Aug. 20, 2021 Researchers detail how a ubiquitous signaling molecule plays a critical role in male fertility, orchestrating key steps that promote sperm motility, survival and fertilization ...
June 21, 2021 Sperm size varies dramatically among different animal species. But why is sperm size so variable when they share the same job -- to fertilize eggs? Researchers now show that animal sperm evolution ...
July 14, 2022 A groundbreaking study has uncovered 14,000 unique sites in DNA that together form the most elementary blueprint for embryogenesis -- the creation of ...
