New technology solves mystery of respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it's doing respiration—using oxygen to generate cellular energy—differently from other organisms such as plants, animals or yeasts. ...

Exponential scaling of frictional forces in cells

AMOLF researchers have presented a theory that describes the friction between biological filaments that are crosslinked by proteins. Surprisingly, their theory predicts that the friction force scales highly nonlinearly with ...

Imaging method highlights new role for cellular 'skeleton' protein

While your skeleton helps your body to move, fine skeleton-like filaments within your cells likewise help cellular structures to move. Now, Salk researchers have developed a new imaging method that lets them monitor a small ...

Protein linked to cancer acts as a viscous glue in cell division

An over-abundance of the protein PRC1, which is essential to cell division, is a telltale sign in many cancer types, including prostate, ovarian, and breast cancer. New research, published online today in Developmental Cell, ...

Technologies for the sixth generation cellular network

Future wireless data networks will have to reach higher transmission rates and shorter delays, while supplying an increasing number of end devices. For this purpose, network structures consisting of many small radio cells ...
