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. ...

How some tissues can 'breathe' without oxygen

Humans need oxygen molecules for a process called cellular respiration, which takes place in our cells' mitochondria. Through a series of reactions called the electron transport chain, electrons are passed along in a sort ...

Upgraded code reveals a source of damaging fusion disruptions

Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and Los Alamos National Laboratory have uncovered a key process behind a major challenge called thermal quenches, the rapid heat loss ...

Ion and lipid transporters specialize for their niche

Cell viability requires that a variety of functions at the cell membrane are maintained properly. P-type ATPases translocate substrates across the membrane, and they have evolved into different types taking care of specific ...

'Bite' defects revealed in bottom-up graphene nanoribbons

Graphene nanoribbons (GNRs), narrow strips of single-layer graphene, have interesting physical, electrical, thermal, and optical properties because of the interplay between their crystal and electronic structures. These novel ...
