Researchers discern the shapes of high-order Brownian motions

For the first time, scientists have vividly mapped the shapes and textures of high-order modes of Brownian motions—in this case, the collective macroscopic movement of molecules in microdisk resonators—researchers at ...

Researchers explain emergence of bacterial vortex

When a bunch of B. subtilis bacteria are confined within a droplet of water, a very strange thing happens. The chaotic motion of all those individual swimmers spontaneously organizes into a swirling vortex, with bacteria ...

A brake for spinning molecules

Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in Denmark and the Max Planck Institute for Nuclear Physics in Heidelberg, ...

It's a negative on negative absolute temperatures

The concept of a perpetual motion machine is an enticing one: Imagine a machine that runs continuously without requiring any external energy—a feat that could make refueling vehicles a thing of the past.

Best image yet of atoms moving in real time produced (w/ video)

Call it the ultimate nature documentary. Scientists at the University of Toronto have recorded atomic motions in real time, offering a glimpse into the very essence of chemistry and biology at the atomic level. Their recording ...

Physics at the threshold of hearing

(Phys.org) —The mammalian auditory system is one of the most sensitive detectors found in nature. Two kinds of cells, the inner and outer hair cells, work together to transduce mechanical vibrations into action potentials. ...
