Study sheds light on genetic 'clock' in embryonic cells

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating ...

Scientists solve a mystery of bacterial growth and resistance

Scientists at The Scripps Research Institute have unraveled a complex chemical pathway that enables bacteria to form clusters called biofilms. Such improved understanding might eventually aid the development of new treatments ...

A game of pool in the live cell

Cells need to react to environmental changes and maintain a balanced system of signaling cascades within the cell. Proteins outside of the cell, on the cellular surface, inside the cellular membrane, and within the cell orchestrate ...

Cell biology: How mitochondria report stress

Ludwig Maximilian University of Munich researchers have discovered the mechanism by which the protein DELE1 detects organelle stress. This offers a possible new approach for treating neurodegenerative diseases.

Mitochondrial unfolded protein response signals imminent danger

Misfolded proteins must be promptly eliminated as they can form toxic aggregates in cells. LMU biologists have studied how this process is triggered in mitochondria and identified a general alarm signal that activates it.

High-fat diets plus extra protein make for bad mix

It's basically a given that diets loaded with fat can lead to considerable health problems. But a new study in the April issue of Cell Metabolism, a Cell Press publication, shows that in some cases diets that are high in ...
