Gene expression altered by direction of forces acting on cell

Tissues and cells in the human body are subjected to a constant push and pull—strained by other cells, blood pressure and fluid flow, to name a few. The type and direction of the force on a cell alters gene expression by ...

How bacteria adhere to fiber in the gut

Researchers have revealed a new molecular mechanism by which bacteria adhere to cellulose fibers in the human gut. Thanks to two different binding modes, they can withstand the shear forces in the body. Scientists of the ...

Putting cells under pressure

As cells divide to form tissues and organs in multicell organisms, they move to where they belong, informed by a series of cues that scientists have yet to observe or fully understand.

The culprit of some GaN defects could be nitrogen

As silicon-based semiconductors reach their performance limits, gallium nitride (GaN) is becoming the next go-to material to advance light-emitting diode (LED) technologies, high-frequency transistors and photovoltaic devices. ...
