This microscope image provided by Osaka University and the Research Institute of Molecular Pathology in October 2024, shows the fertilization of a mouse egg marked in red and green. DNA is marked in ...

Sperm are basically cells with a tail. It can seem surprising that they are able to navigate and swim with purpose. New research has shown that sperm are even able to switch up directions, and alter ...

Sperm cells are known to prefer cooler temperatures. For quite some time, a puzzling question for scientists has been: how do temperature-sensitive swimmers actually operate effectively within the ...

Using Google’s AlphaFold, researchers identified the bundle of three sperm proteins that seem to make sexual reproduction possible. By Elizabeth Preston They’re the original odd couple: One is massive ...

During fertilisation, the egg cell and the sperm are bound together by, among other things, two specific proteins. Researchers have now demonstrated that this represents a special type of binding, ...

It's a Wednesday morning at the National Academies of Sciences, Engineering and Medicine in downtown Washington, D.C., and Dr. Eli Adashi is opening an unprecedented gathering: It's titled "In-Vitro ...

To enable our fingernails to grow or new skin to form and heal an injury, our cells make copies of themselves — exact duplicates containing the same DNA, the combination of 46 chromosomes that makes ...

The video in question was published in a 2016 issue of the peer-reviewed scientific journal Nano Letters, and showed a so-called “spermbot” propelling immotile sperm toward an egg cycle in a petri ...

How a sperm and an egg fuse together has long been a mystery. New research by scientists in Austria provides tantalizing clues, showing fertilization works like a lock and key across the animal ...

An egg cell and a sperm need to hold together tightly in the Fallopian tube in order to fuse, resulting in the creation of a new organism. One key part of this process involves the proteins Juno, on ...
