Researchers have uncovered a complex biological process that protects germ cells, the precursor cells to sperm, from genetic ...

New insights into a sophisticated process that protects sperm cells has revealed a mechanism, similar to an immune system, thwarts genetic chaos during the earliest stages of their development.

By Dr. Priyom Bose, Ph.D. A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the ...

Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics .. | Cell And ...

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as two papers in ...

New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

A study finds that brief immune stress in male mice can leave lasting metabolic and behavioral effects in offspring through ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is ...

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...
