Sugar mimics guide stem cells toward neural fate
Many growth factors that influence the fate of embryonic stem cells must bind to sugars attached to specific receptors on the surface of the cell to work. Because the sugars are difficult to manipulate, biochemists created synthetic stand ins that helped to identify substructures recognized by a growth factor involved in neural development.

Protons power protein portal to push zinc out of cells
Researchers at The Johns Hopkins University report they have deciphered the inner workings of a protein called YiiP that prevents the lethal buildup of zinc inside bacteria. They say understanding YiiP's movements will help in the design of drugs aimed at modifying the behavior of ZnT proteins, eight human proteins that are similar to YiiP, which play important roles in hormone secretion and in signaling between neurons.

Family of proteins plays key role in cellular pump dynamics
Case Western Reserve University scientists have discovered how a family of proteins -- cation diffusion facilitators -- regulates an important cellular cycle where a cell's energy generated is converted to necessary cellular functions. The finding has the potential to inform future research aimed at identifying ways to ensure the process works as designed and, if successful, could lead to significant breakthroughs in the treatment of Parkinson's, chronic liver disease and heart disease.

Familiar yet strange: Water's 'split personality' revealed by computer model
Using computer models, Princeton University researchers found that as water freezes it takes on a sort of split personality wherein, at very cold temperatures and above a certain pressure, it may spontaneously split into two liquid forms. Finding this dual nature could lead to a better understanding of how water behaves in high-altitude clouds, which could improve the predictive ability of current weather and climate models.

Protein could put antibiotic-resistant bugs in handcuffs
A team from Duke and the University of Sydney has solved the structure of a key protein that drives DNA copying in the plasmids that make staphylococcus bacteria antibiotic resistant. Knowing how this protein works may now help researchers devise new ways to stop the plasmids from spreading antibiotic resistance in staph by preventing the plasmids from copying themselves.
