Signaling molecule may regulate proteins in wheat plants

Triggers for food crop growth are complex and new research by South Australian plant scientists is investigating one way wheat responds to common stresses such as poor soil health.

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. ...

Exploring flow transport in egg cells

Northwestern Medicine scientists discovered a new and unique transport mechanism within developing egg cells in fruit flies, according to a study published in eLife.

Protein structure offers clues to drug-resistance mechanism

MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria become resistant to multiple ...

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 ...
