Melting glaciers contribute to Alaska earthquakes

In 1958, a magnitude 7.8 earthquake triggered a rockslide into Southeast Alaska's Lituya Bay, creating a tsunami that ran 1,700 feet up a mountainside before racing out to sea.

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 ...

Using physics to improve root canal efficiency

Scientists used computational fluid dynamics to determine the effect of temperature on root canal cleaning efficiency. Higher temperatures can, to a point, improve cleansing, but this benefit falls off if the temperature ...

'Unboil an egg' machine creates improved bacteria detector

Traditional fluorescent dyes to examine bacteria viability are toxic and suffer poor photostability—but using the VFD has enabled the preparation of a new generation of aggregation-induced emission dye (AIE) luminogens ...

Blood flows could be more turbulent than previously expected

Blood flow in the human body is generally assumed to be smooth due to its low speed and high viscosity. Unsteadiness in blood flow is linked to various cardiovascular diseases and has been shown to promote dysfunction and ...
