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 ...

Gaining insight into the energy balance of earthquakes

Researchers at EPFL's Computational Solid Mechanics Laboratory and the Weizmann Institute of Science have modeled the onset of slip between two bodies in frictional contact. Their work, a major step forward in the study of ...

X-ray mapping enhances potential of lightweight magnesium

A world-first study led by Monash University has discovered a technique and phenomenon that can be used for creating stronger, lightweight magnesium alloys that could improve structural integrity in the automobile and aerospace ...

'Aneurysm Number' may help surgeons make treatment decisions

Aneurysms form as abnormal bulges or balloonings over an artery, and, if ruptured, can lead to serious health complications or even death. Some aneurysms can exist for a long time without rupturing, and the surgery involved ...

Rosetta's comet sculpted by stress

Feeling stressed? You're not alone. ESA's Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov–Gerasimenko has been a key process in sculpting the comet's surface and interior ...

After the Big One: Understanding aftershock risk

In early September 2018, a powerful earthquake on the island of Hokkaido in northern Japan triggered landslides, toppled buildings, cut power, halted industry, killed more than 40 people and injured hundreds. The national ...
