Metabolic diseases such as obesity, fatty liver, and insulin resistance are rapidly increasing worldwide, but fundamental methods to regulate the process of fat formation remain limited. In particular ...
Researchers often use a nematode worm called Caenorhabditis elegans (C. elegans) to study human genetics because at the molecular level, we have a lot in common with these organisms. Scientists used a ...
A hidden form of evolution inside aging sperm may quietly raise genetic risks for the next generation. Credit: Shutterstock Harmful genetic mutations in sperm become much more common as men grow older ...
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 ...
A sperm donor whose samples helped conceive nearly 200 children across Europe unknowingly carried a cancer-causing genetic mutation — a hidden risk now tied to multiple childhood illnesses and early ...
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 ...
It has only recently become known that two parallel systems of blood formation exist in the body, originating from different precursor cells. Researchers at the German Cancer Research Center (DKFZ) ...
This study characterized the function of SLC35G3, a putative transmembrane UDP-N-acetylglucosamine transporter, in spermatogenesis. They showed that SLC35G3 is testis-specific and expressed in round ...
Oct. 31, 2025--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 ...
