Helium anomaly preceded Mount Ontake eruption

University of Tokyo researchers discovered an increase in a helium isotope during a ten-year period before the 2014 Mount Ontake eruption in central Japan. The finding suggests that this helium isotope anomaly is related ...

Researchers observe how nanoparticles grow when exposed to helium

A team of researchers from the University of Leicester and France's G2ELab-CNRS in Grenoble have for the first time observed the growth of free nanoparticles in helium gas in a process similar to the decaffeination of coffee, ...

Evidence of a local hot bubble carved by a supernova

I spent this past weekend backpacking in Rocky Mountain National Park, where although the snow-swept peaks and the dangerously close wildlife were staggering, the night sky stood in triumph. Without a fire, the stars, a few ...

Up in the sky: It's a nuclear explosion

If you live in the southern hemisphere, you now can safely view the aftermath of a nuclear explosion from the comfort of your own backyard.

Researching new detectors for chemical, biological threats

Sandia National Laboratories scientists are thinking small, building on decades of sensor work to invent tiny detectors that can sniff out everything from explosives and biotoxins to smuggled humans.

Physicists create tabletop antimatter 'gun'

(Phys.org) —An international team of physicists working at the University of Michigan has succeeded in building a tabletop antimatter "gun" capable of spewing short bursts of positrons. In their paper published in the journal ...

Superfluids: Observation of 'second sound' in a quantum gas

Second sound is a quantum mechanical phenomenon, which has been observed only in superfluid helium. Physicists from the University of Innsbruck, Austria, in collaboration with colleagues from the University of Trento, Italy, ...
