Research into how a father’s choices — such as diet, exercise, stress, nicotine use — may transfer traits to his children has become impossible to ignore. The standard sperm-meets-egg story posits ...

But watching how the flu virus sneaks into cells has been difficult because standard microscopes can't capture these fast, tiny steps clearly. In a breakthrough study, scientists from Switzerland and ...

Scientists have identified a protein that may be key to proper sperm formation. Without it, male mice produced no viable sperm, they found. A team at the RIKEN Center for Biosystems Dynamics Research ...

Researchers recently developed a bone marrow model to study how the body generates cells. Interestingly, this model is the first of its kind to be developed entirely from human cells. Not only can ...

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system captures both detailed structures and tiny moving particles at ...

Neil Hunter's laboratory in the UC Davis College of Biological Sciences has placed another piece in the puzzle of how sexual reproduction shuffles genes while making sure sperm and eggs get the right ...

Researchers at the Columbia University Fertility Center reported the first successful pregnancy using an AI-guided method they developed to recover sperm in men with azoospermia, in which ejaculate ...

In a proof-of-concept experiment, scientists demonstrated that you can create and fertilize human eggs in the lab using sperm, genes from skin cells, and the "shells" of existing egg cells. When you ...

This undated image provided by the Mitalipov Laboratory at Oregon Health & Science University shows a a microscope image of a human egg that contains a nucleus taken from a skin cell. (Mitalipov ...

WASHINGTON (AP) — Oregon scientists used human skin cells to create fertilizable eggs, a step in the quest to develop lab-grown eggs or sperm to one day help people conceive. But the experiment ...

Scientists have created human eggs containing genes from adult skin cells, a step that someday could help women who are infertile or gay couples have babies with their own genes but would also raise ...
