Frictionless supersolid a step closer

Superfluid mixtures of atoms can boil and freeze at ultra-low temperatures. This freezing can result in the formation of supersolids of atoms that can flow alongside each other without friction, but are still set in a fixed ...

Using magnets to help prevent heart attacks

If a person's blood becomes too thick it can damage blood vessels and increase the risk of heart attacks. But a Temple University physicist has discovered that he can thin the human blood by subjecting it to a magnetic field.

Geologists simulate deep earthquakes in the laboratory

More than 20 years ago, geologist Harry Green, now a distinguished professor of the graduate division at the University of California, Riverside, and colleagues discovered a high-pressure failure mechanism that they proposed ...

How people work... and the mystery of your fingerprints

Why do we chew our food? Research has shown that it is not, as has long been presumed, to make chunks of food small enough to swallow without choking. Biomechanics, who have modelled the cohesive strength of food after a ...

Earthquakes generate big heat in super-small areas: study

Most earthquakes that are seen, heard, and felt around the world are caused by fast slip on faults. While the earthquake rupture itself can travel on a fault as fast as the speed of sound or better, the fault surfaces behind ...

Finnish researchers find explanation for sliding friction

Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, but the fundamental origin ...
