PRM-DNA aggregates dynamics under HS-AFM. The scanning area, 100 nm × 100 nm, was taken with 100 × 100 pixels at 300 millisec per frame (scale bar: 20 nm). Credit: Nucleic Acids Research (2025 ...

WashU Medicine researcher Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology, has shown in mice that sperm have a temperature-controlled switch that changes their ...

Polina Lishko, PhD, a BJC Investigator and professor of cell biology and physiology at WashU Medicine All mammals share a particular protein embedded in the surface of sperm called CatSper.

The race will be monitored via advanced imaging technologies and high-resolution cameras, with the winner being the first sperm cell to cross the designated “finish line.” The visual feed will ...

In most cells, DNA is wrapped around proteins called histones, allowing it to be loosely packed and accessible for gene activity. However, in sperm cells, histones are replaced by protamines, which ...

A commentator yelled excitedly as hundreds of spectators stood glued to a video of a racecourse — but the athletes they were rooting for were tiny sperm cells. The unusual sport was invented by ...

On-site doctors prepared the swimmers for the race by diluting the samples, placing them in a centrifuge, and then narrowing down the millions of sperm cells to the hundred that would become the final ...

A MAN has received the world's first sperm-making stem cell transplant in a groundbreaking experiment to reverse infertility. Jaiwen Hsu, 26, has azoospermia, a condition where no sperm is present ...

But only recently have they been able to describe how it affects sperm cells, bending their shape, slowing them down and changing their genetic material. It’s not surprising, since many ...

Then he’s contacted by the Special Activities division for the Genetic Compliance Department and asked to infiltrate a Ghost Cell of fellow mods employed by a shady billionaire who promises the ...
