A toxic protein forms dynamic pores in the membranes of brain cells—and that may be the key to understanding how Parkinson's disease develops. This is the conclusion of a new study from Aarhus ...

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 ...

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 ...

Cumulus Media’s four-station group in Des Moines has a new VP/Market Manager, and he’s in-bound from Steel City Media in Kansas City, where he was a senior marketing consultant. Sines’ experience ...

Abstract: Oocyte denudation is the procedure of removing the cumulus cells encasing an oocyte to expose the oocyte itself. During oocyte maturation, cumulus cells play a crucial role in providing ...

This important study reports the conservation of sperm-egg envelope binding by demonstrating successful recognition of the micropyle in fish eggs by mouse sperm. The evidence supporting the ...
