An electron microscope image of a mammalian cell with organelles depicted. In autophagy, some elements of a cell are degraded and recycled to generate nutrients and energy to sustain and preserve the ...

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 ...

Primary cilia are sensory organelles present on the cell surface; however, their physical structure has not been defined due to technical reasons. A new PNAS study examined primary cilia in human ...

Forget about locating molecules in the blink of an eye, which takes as long as a quarter second—far too long a time to distinguish a sequence of subcellular events. Instead, try doing what Stanford ...

BESSY II's high-brilliance X-rays can be used to produce microscopic images with spatial resolution down to a few tens of nanometers. Whole cell volumes can be examined without the need for complex ...
