First proof that 'plunging regions' exist around black holes in space

An international team led by researchers at Oxford University Physics have proved Einstein was correct about a key prediction concerning black holes. Using X-ray data to test Einstein's theory of gravity, their study gives ...

You leave a 'microbe fingerprint' on every piece of clothing you wear—and it could help forensic scientists solve crimes

When you think of a criminal investigation, you might picture detectives meticulously collecting and analyzing evidence found at the scene: weapons, biological fluids, footprints and fingerprints. However, this is just the ...

Droplets that swim toward dissolution could inspire fluid microbots

Researchers discovered that microscopic liquid droplets swim toward solvent conditions that favor their dissolution. This mechanism may underlie some transport processes within living cells, and could be exploited to develop ...

New method can create aquatic levitation at much lower temperature, has implications for cooling nuclear reactors

Splash a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the droplets of water seem to roll and float, hovering above the surface.

Researchers show how to use 'topological tweezers' to control active fluids

University of Michigan physicists have devised a way to manipulate active fluids, a type of fluid composed of individual units that can propel themselves independently, by taking advantage of topological defects in the fluids.

The origin of the sun's magnetic field could lie close to its surface

The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is ...

First observation of a focused plasma wave on the sun

For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a ...
