Light and sound waves reveal negative pressure

Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers at the Max Planck Institute for the Science of Light (MPL) in Erlangen have now ...

New research explains 'Atlantification' of the Arctic Ocean

New research by an international team of scientists explains what's behind a stalled trend in Arctic Ocean sea ice loss since 2007. The findings indicate that stronger declines in sea ice will occur when an atmospheric feature ...

Watching a bimetallic catalytic surface in action

A team of researchers from the Department of Interface Science at the Fritz Haber Institute of the Max Planck Society addressed the question: what happens to a Ga-promoted Cu surface under reaction conditions required for ...

Researchers discover tin hydride with properties of strange metal

Scientists from Skoltech, the Shubnikov Institute of Crystallography, and the Center for High Pressure Science and Technology Advanced Research (HPSTAR) in Beijing, China, are exploring the superconductivity of polyhydrides—compounds ...

The physics of fat droplets reveal DNA danger

Fat is a normal and necessary part of the body. Fat cells store and release energy, as well as play significant roles in hormonal regulation and immunity.

Scientists skeptical of superconductor claims that went viral

A recent claim by South Korean researchers that they have created a material which works as a superconductor at room temperature—long a holy grail of physics—has been met with huge excitement on social media but skepticism ...

New property of hydrogen predicted

Hydrogen is the most common element in the universe. It determines the properties of stars and planets and is crucial for life on Earth—not least because of its role in climate-neutral energy supply. Generations of scientists ...
