Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th-century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

This is an electron microscopy picture of a section through the flagellum of a Drosophila melanogaster sperm cell. The base of the flagellum is on the left, and the falgellum's skeleton extends from ...

Science X is a network of high quality websites with most complete and comprehensive daily coverage of the full sweep of science, technology, and medicine news ...

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 ...

For more than 50 years, freeze-fracture electron microscopy has been widely accepted as a significant method in microscopic structural and biological research. Although components of the approach were ...

Structure of the newly decoded protein found in the membrane of sperm cells. Colours mark the different units of the protein, which can be put together to make a functioning protein like the building ...
