With a so-called cryo plasma-FIB (Plasma Focused Ion Beam) scanning electron microscope with nanomanipulator, Goethe University in Frankfurt (Germany) is expanding its research infrastructure with a ...

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 ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

For a few weeks in 2017, Wanda Kukulski found herself binge-watching an unusual kind of film: videos of the insides of cells. They were made using a technique called cryo-electron tomography (cryo-ET) ...

New York, NY (Dec. 20, 2017) -- Columbia University Medical Center (CUMC) researchers have obtained the first detailed snapshots of the structure of a membrane pore that enables epithelial cells to ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

Researchers have used advanced electron microscopes to delve deeper into the process of protein degradation. They described the structure of a key enzyme that helps mediate ubiquitination in yeast, ...
