Human sperm may get LOST in zero gravity, study claims

Sperm navigation is significantly impaired in microgravity, posing challenges for reproduction in space.

Ancient viral DNA helps human embryos develop

Research suggests that ancient viral DNA embedded in the human genome is playing a key role in early embryo development. Around 8% of our genome consists of endogenous retrovirus DNA - the remnants of ancient infections, but knowledge of their activity is limited. Now, a team shows that these sequences are required for the correct development of lab-derived embryo analogues, and for the switching on of human-specific genes.

See the First-Ever 3D Images of Human Embryo Implantation

Real-time imaging of human embryo implantation could enhance in vitro fertilization success rates.

Understanding embryo movements may lead to targeted treatments for implantation.

Implantation failure is a significant cause of infertility, responsible for many miscarriages.
