Bacterial decision-making deciphered

Scientists have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to...

How cells take out the trash

A recent study demonstrates that individual cells that make up such biological organisms as humans have sophisticated methods for managing waste.

Protein-RNA interactions in living cells

Researchers have developed a genome-wide platform to study how specialized proteins regulate RNA in living, intact cells.

Communications within a cell

Scientists have discovered how the calcium sensor protein calmodulin can gauge the local flow of calcium and global calcium flow entering the many channels across the entire cell.

Biofilm battleground

Bacteria often grow in crowds on surfaces where they form a community together. These biofilms develop on any surface that bacteria can attach themselves to.

Regulating cell movement

The mechanism by which a cell controls its movement within tissue by way of cell adhesion has been revealed in the laboratory.

Vitamin A incites cancer growth

Vitamin A has been found to promote cancer by turning on genes that cause stem cells embedded in a tumour to transform into endothelial cells that link to the body's blood supply.

Cellular decision on the computer

Scientists have simulated how cells decide whether or not to migrate and were able to predict the molecular targets within a cell that needs to be targeted for the process to occur.

Managing cell maintenance

Scientists identified a new mechanism of the UVRAG tumour suppressor in regulating how a cell digests its own content in order to maintain homeostasis.

Microscaffolding therapy to treat stroke damage

Scientists are developing cell-scaffold combinations that could be injected into the brain to provide a framework inside the cavities caused by stroke.

Turning cells into fat

Researchers report the discovery of a critical early player, so-called 3T3-L1 cells, in the path that turns cells to fat.

50,000th molecule structure

The Protein Data Bank (PDB) based at Rutgers, The State University of New Jersey, and the University of California-San Diego (UCSD) this month reached a significant milestone.

Cellular transport insight

Scientists have now discovered how molecular motors transport cargoes in cells. Two competing teams of motors pull in opposite directions, like in a tug-of-war contest.

epMotion 5070 CB automated liquid handling system

Designed to fit inside a laminar flow hood, the epMotion 5070 CB automated liquid handling system from Eppendorf AG offers important advantages for cell biologists.

H pylori adhesion

The Gram negative bacterium H pylori is involved in the pathogenesis of several gastrointestinal diseases, ultimately leading to gastric carcinoma.
