Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons ...
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 ...
Immune cells called double negative T cells are abundant in the intestine but have been poorly understood till date. In a recent study, researchers from the Institute of Science Tokyo report that ...
