Swirling bacteria mimic Van Gogh's 'The Starry Night'

Scientists have discovered a way to transform millions of predatory bacteria into swirling flash mobs reminiscent of painter Vincent Van Gogh's "The Starry Night" as the unexpected result of experiments on a genetic circuit ...

Uncovering molecular mechanisms behind cell signaling

A study led by Northwestern Medicine investigators has identified the molecular mechanisms within protein complexes that promote cell-to-cell adhesion and communication, according to findings published in the Proceedings ...

How density governs receptor activation on immune cells

Scientists from within the Antibody and Vaccine Group at the University of Southampton have gained novel insights into how an important class of immune receptors called tumor necrosis factor receptors (TNFR) are activated.

Scientists discover ancient enzymes evolve new tricks

Plants, herbivores, and pathogens are locked in a war for survival that is hundreds of millions of years old. Rooted in place and with no way to run, plants evolved complex, chemical-producing machinery in their cells to ...
