Physicists investigate the cause of striped patterns formed by fine particles deposited on surfaces
Patterns fascinate. Particularly stripes. Found in nature in zebras, they are also found in the most unlikely places, such as powdered drugs' mixing vessel walls. In an article about to be published in the European Physical Jo ...

Accelerators can search for signs of Planck-scale gravity
(Phys.org)—Although quantum theory can explain three of the four forces in nature, scientists currently rely on general relativity to explain the fourth force, gravity. However, no one is quite sure of ...

Physicists extend special relativity beyond the speed of light
(Phys.org)—Possibly the most well-known consequence of Einstein's theory of special relativity is that nothing can travel faster than the speed of light, c. According to the mass-energy equivalence formul ...

New Research Investigates How Diseases Spread in Primates
A star’s dying scream may be a beacon for physics
When a star suffered an untimely demise at the hands of a hidden black hole, astronomers detected its doleful, ululating wail — in the key of D-sharp, no less — from 3.9 billion light-years away. ...

Invisible volcanic ash gives clues to Neanderthal demise
(Phys.org) -- Invisible to the human eye, cryptotephra is a fine volcanic glass that is blasted out of erupting volcanoes along with ash. It leaves behind a hidden layer, in the earth, which has now been detected, ...
