Heading towards a tsunami of light

Researchers have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way.

Researchers use muon detector to measure electric potential in a thunderstorm

A team of researchers from several institutions in India and Japan has found that it is possible to use a muon detector to measure electric potential in thunderstorms. The paper is published in the journal Physical Review Letters. The researchers explain that they noticed muon detection levels drop during thunderstorms, and used that information to calculate electric potential in thunderstorms.

How heavy elements come about in the universe

Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). This occurs at extremely high temperatures, but at relatively low energies. An international research team headed by Goethe University has now succeeded in investigating the capture of protons at the storage ring of the GSI Helmholtzzentrum für Schwerionenforschung.

Dalian Coherent Light Source reveals hydroxyl super rotors from water photochemistry

Scientists at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences recently revealed hydroxyl super rotors from water photochemistry by using the Dalian Coherent Light Source (DCLS). The researchers, under the direction of Prof. Yuan Kaijun and Prof. Yang Xueming, published their findings in Nature Communications.

Semimetals are high conductors

Researchers have measured high conductivity in very thin layers of niobium arsenide, a type of material called a Weyl semimetal. The material has about three times the conductivity of copper at room temperature.

Supercrystal: A hidden phase of matter created by a burst of light

'Frustration' plus a pulse of laser light resulted in a stable 'supercrystal.'

Long-distance quantum information exchange -- success at the nanoscale

Researchers have realized the swap of electron spins between distant quantum dots. The discovery is a step towards applications of quantum information, as the dots leave enough room for delicate control electrodes, enabling integration with traditional microelectronics and perhaps, a future quantum computer.

Trembling aspen leaves could save future Mars rovers

Researchers at the University of Warwick have been inspired by the unique movement of trembling aspen leaves, to devise an energy harvesting mechanism that could power weather sensors in hostile environments and could even be a back-up energy supply that could save and extend the life of future Mars rovers.

Fermilab, partners break ground on particle accelerator to study ghostly particles, new forces

Fermi National Accelerator Laboratory officially broke ground March 15 on a major new particle accelerator project that will power cutting-edge physics experiments for many decades to come.
