Cellular mechanical forces may initiate angiogenesis

Pericytes, the contractile cells surrounding capillaries, may use mechanical forces to initiate angiogenesis, the "sprouting" of new blood vessels, according to researchers at Tufts University School of Medicine (TUSM) and ...

Nailing down a crucial plant signaling system

Plant biologists have discovered the last major element of the series of chemical signals that one class of plant hormones, called brassinosteroids, send from a protein on the surface of a plant cell to the cell's nucleus. ...

Dynamic risk management in cell populations

Much like investors in the stock market, cell populations prepare for changes in the environment by spreading the risk. The tool box they use contains a repertoire of sensory receptors on the surface of individual cells. ...

Bacteria have a sense of touch

Although bacteria have no sensory organs in the classical sense, they are still masters in perceiving their environment. A research group at the University of Basel's Biozentrum has now discovered that bacteria not only respond ...

New tools developed to unveil mystery of the 'glycome'

Scientists at The Scripps Research Institute have developed chemical compounds that can make key modifications to common sugar molecules ("glycans"), which are found on the surface of all cells in our body. The new study ...
