Researchers show stem cell fate depends on 'grip'

A team of researchers from the University of Pennsylvania has generated new insight on how a stem cell's environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or bone cells depends partially on how well they can "grip" the material they are growing in.

The first caffeine-'addicted' bacteria

Some people may joke about living on caffeine, but scientists now have genetically engineered E. coli bacteria to do that - literally. They describe bacteria being 'addicted' to caffeine in a way that promises practical uses ranging from decontamination of wastewater to bioproduction of medications for asthma.

Computer simulations yield clues to how cells interact with surroundings

Berkeley Lab scientists have developed a computer model of a protein that helps cells interact with their surroundings. Like its biological counterpart, the virtual integrin snippet is about twenty nanometers long. It also responds to changes in energy and other stimuli just as integrins do in real life. The result is a new way to explore how the protein connects a cell's inner and outer environments.
