Human sperm have long been a subject of fascination—not just for their role in fertilization, but for their remarkable ability to navigate through some of the most viscous environments in the body.

Researchers have combined two microscopic imaging techniques in one microscope, providing scientists with a high-resolution method of tracking single molecules in a cellular context. The development ...

The latest study from the Sharma Lab makes the mechanisms of how epigenetic information is established in sperm cells, and how that encoding affects offspring health, a little less of a scientific ...

If you look at a mouse sperm cell through a microscope, as postdoctoral researcher Kristin Hook did hundreds of times while working in Heidi Fisher’s lab at the University of Maryland, College Park, ...
