Nanometre-scale gold particles are currently intensively investigated for possible applications in catalysis, sensing, photonics, biolabelling, drug carriers and molecular electronics. The particles are prepared in a solution from gold salt…
ESA’s Cluster satellites have flown through a natural particle accelerator just above Earth’s atmosphere. The data they collected are unlocking how most of the dramatic displays of the northern and southern lights are generated.
Two of Clust…
The scientists have now carried out the first full run of experiments that smash protons together at almost the speed of light. When these sub-atomic particles collide at the heart of the CMS detector, the resultant energies and densities are simila…
Clues to future climate may be found in the way an ordinary drinking glass shatters.
Results of a study published this week in the journal Proceedings of the National Academy of Sciences find that microscopic particles of dust can break apart …
BOULDER–Clues to future climate may be found in the way that an ordinary drinking glass shatters.
A study appearing this week in Proceedings of the National Academy of Sciences finds that microscopic particles of dust, emitted into the atmo…
ANN ARBOR, Mich.—Under just the right conditions—which involve an ultra-high-intensity laser beam and a two-mile-long particle accelerator—it could be possible to create something out of nothing, according to University of Michigan researche…
Whenever two pieces of metal at different voltages are brought near each other, as when an appliance is plugged into a live socket, there is a chance there will be an arc between them. Most of the arcs people see are a breakdown of the gas bet…
Two spacecraft are now beginning to study the moon’s environment as part of NASA’s ARTEMIS mission, whose principal investigator is Vassilis Angelopoulos, a UCLA professor of Earth and space sciences.
One of these satellites has been in the luna…
Atmospheric fine particles affect the Earth’s radiation balance by interacting with solar radiation and by participating in cloud formation. Biogenic volatile organic compounds are key players in new particle formation processes. Hence, terrestrial …
A team of environmental engineers, who might better be called “archeologists of the air,” have, for the first time, isolated aerosol particles in near pristine pre-industrial conditions.
Working in the remote Amazonian Basin north of Manaus, Brazi…
Animal flocks, be it honeybees, fish, ants or birds, often move in surprising synchronicity and seemingly make unanimous decisions at a moment’s notice, a phenomenon which has remained puzzling to many researchers.
New research published today, We…
