Unraveling bacterial behavior

Bacteria encounter a constant barrage of ever-changing temperature, acidity and chemical stimuli from their environment. The cells must absorb all of this information and choose the correct response—whether boosting their ...

Breakthrough: Sensors monitor cells at work

Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell's outer membrane, which seals and protects all living cells, to the cell's interior. These transported molecules ...

Jigsaw a critical piece of the Notch puzzle

The Notch signaling pathway helps determine cell fate determination, differentiation and proliferative ability of numerous cells. How it accomplishes these tasks has been a puzzle, but researchers led by those at Baylor College ...

Unusual protein helps regulate key cell communication pathway

Charged atoms, or ions, move through tiny pores, or channels, embedded in cell membranes, generating the electrical signals that allow cells to communicate with one another. In new research, scientists have shown how an unusual ...

Protein love triangle key to crowning bees queens?

A honey bee becomes a royal queen or a common worker as a result of the food she receives as a larva. While it has been well established that royal jelly is the diet that makes bees queens, the molecular path from food to ...

Chemists reveal the force within you

A new method for visualizing mechanical forces on the surface of a cell, reported in Nature Methods, provides the first detailed view of those forces, as they occur in real-time.
