In the quest to address infertility, Cornell University researchers have developed a groundbreaking device that could simplify and automate oocyte cumulus removal, a critical step in assisted ...

In fertility treatments like assisted reproductive technologies (ART), including IVF and ICSI, an important step is cleaning the egg by removing the surrounding cumulus cells. This is usually done by ...

The fertilization of an egg by a sperm is central to human reproduction. A complex biological process transforms immature oocytes into ones that can be fertilized. The process begins in the female ...

Spaceflight makes certain human stem cells age faster, a new study has found, furthering scientists’ understanding of the potential effects of space exploration on the human body. Stem cells are found ...

An international team led by researchers at Lund University in Sweden has identified the molecular tools needed to reprogram ordinary cells into specialized immune cells. The discovery, published in ...

Some might say it looks like a finger. Others might see a worm. Scientists in the field often liken it to an antenna. The technical name is primary cilium. This slender, microscopic appendage juts out ...
