Today's physics/chemistry headlines from the sources selected by our team:

Researchers demonstrate ultra low-field nuclear magnetic resonance using Earth's magnetic field
Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided the basis for a technique which might, one day, be used to characterize the chemical composition of fluid mixtures in their native environments.

Bubbling down: Discovery suggests surprising uses for common bubbles
Anyone who has ever had a glass of fizzy soda knows that bubbles can throw tiny particles into the air. But in a finding with wide industrial applications, Princeton researchers have demonstrated that the bursting bubbles push some particles down into the liquid as well.

Researchers create wind-powered mechanoluminescent lighting material
(Phys.org) —A team of researchers at South Korea's Daegu Gyeongbuk Institute of Science and Technology has created an elastic-mechanoluminescent material that emits light when exposed to wind. At high wind speeds, the material has been shown able to emit light equivalent to a computer screen.

First indirect evidence of so-far undetected strange baryons
(Phys.org) —New supercomputing calculations provide the first evidence that particles predicted by the theory of quark-gluon interactions but never before observed are being produced in heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC), a facility that is dedicated to studying nuclear physics. These heavy strange baryons, containing at least one strange quark, still cannot be observed directly, but instead make their presence known by lowering the temperature at which other strange baryons "freeze out" from the quark-gluon plasma (QGP) discovered and created at RHIC, a U.S. Department of Energy (DOE) Office of Science user facility located at DOE's Brookhaven National Laboratory.

Seeing a molecule breathe through scattering of light pulses
For the first time, chemists have succeeded in measuring vibrational motion of a single molecule with a femtosecond time resolution. The study reveals how vibration of a single molecule differs from the behavior of larger molecular groups. Seeing a single organic bipyridylethylene (BPE) molecule vibrate as a function of time was possible through the scattering of the light pulses. The method is known as time-resolved coherent anti-Stokes Raman scattering (tr-CARS).
