Team proposes new law to accurately measure charged macromolecules

For biochemists, measuring the size and diffusion properties of large molecules such as proteins and DNA using dynamic light-scattering techniques and the Stokes-Einstein formula has been mostly straightforward for decades, ...

Atom-by-atom growth chart for shells helps decode past climate

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and will improve our understanding ...

Ice shelf vibrations cause unusual waves in Antarctic atmosphere

Low-frequency vibrations of the Ross Ice Shelf are likely causing ripples and undulations in the air above Antarctica, a new study finds. Using mathematical models of the ice shelf, the study's authors show how vibrations ...

The quantum sniffer dog

As humans, we sniff out different scents and aromas using chemical receptors in our noses. In technological gas detection, however, there are a whole host of other methods available. One such method is to use infrared lasers, ...

Light-driven atomic rotations excite magnetic waves

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how the ultrafast light-induced modulation of the atomic positions ...
