New theory describes ice's slippery behavior

Winter is coming, promising the usual bouts of frozen precipitation for northern locations. The slickness of snow and ice is a big pain if you're driving, flying or walking, but can be a lot of fun if you strap on a pair ...

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 ...

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.

ELeCt-ing a better candidate for chemo delivery

Chemotherapy has been the backbone of cancer treatment for decades, but it is notorious for its toxicity to healthy cells, severe side effects, and poor targeting of the intended tumors. Efforts to improve chemotherapy's ...

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 ...

From solid to liquid and back again

You can easily walk across the sand on a beach. But step into a ball pit, and chances are you'll fall right through.

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 ...

Better scaffolds help scientists study cancer

Testing treatments for bone cancer tumors may get easier with new enhancements to sophisticated support structures that mimic their biological environment, according to Rice University scientists.

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 ...

'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 ...
