Study shows marine heat waves have significant impact on microorganisms
A new study led by Australia's national science agency, CSIRO, shows that marine heat waves (MHWs) are altering the microorganism communities that form the base of the marine food chain, disrupting coastal ecosystems. The article "A marine heat wave.....»»
Researchers report on recent drought in the eastern Hungarian plains
Intensive agricultural cultivation and the resulting changes in soil structure cause low humidity in the near-surface air during heat waves in really dry years. As a result, summer cold fronts roar across the Great Hungarian Plain without the usual t.....»»
Researchers discover new ways to excite spin waves with extreme infrared light
As demands for computing resources continue to increase rapidly, scientists and engineers are looking for ways to build faster systems for processing information. One possible solution is to use patterns of electron spins, called spin waves, to trans.....»»
A Trojan approach to guide and trap light beams via Lagrange points
Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional approach to guide light waves leverages the total inter.....»»
Investigating effects of invasive trout on native charr in Kamikochi, Nagano
Globally, salmonids have been widely introduced into freshwater areas for aquaculture and recreational angling. brown trout (Salmo trutta), which are native to Europe, and brook trout (Salvelinus fontinalis), which are native to North America, were i.....»»
An efficient numerical program for studying light scattering at the nanoscale
When light encounters a particle, it interacts with the particle instead of just passing through smoothly. The light waves can get scattered in different directions because of the light-matter interactions......»»
Huge tsunami with 20 meter waves may have wiped out Stone Age communities in Northumberland
An enormous tsunami with gigantic waves reaching 20 meters submerged large parts of northern Europe and may have wiped out populations of people in Stone Age Britain, a new University of York study has discovered......»»
