Controlling macrophage behavior via cell shape

Macrophages are immune cells that gobble intruders, renegades and debris. Now researchers discover cell shape can help control macrophages — for instance, elongating them promotes behavior that enhances healing. These findings, detailed in the Proceedings of the National Academy of … Continue reading

A new use for rice — lithium ion batteries

Discarded rice husks could become standard ingredients for lithium ion batteries. Researchers in Korea report that rice husks — the tough, protective layer covering a rice kernel — are ideal sources of silicon for high-capacity lithium battery anodes. Their findings … Continue reading

The physics of clogged arteries: A “micro” story

What do rubber tires from the earliest automobiles have in common with fatty atherosclerotic plaques inside blood vessels in the human body? The way they rupture, it turns out, is driven by the same physical processes. In the 1920s, rubber … Continue reading
