The World Health Organization (WHO) declared the novel coronavirus outbreak a 'Public Health Emergency of International Concern' on the 30th of January (GMT). The world is trembled by the international spread of the novel coronavirus infections. Rapid distribution of medicines including anti-virus are demanded, however, it is very challenging to mass produce them in a short period of time due to complicated process of drug manufacturing.
Dr. Hun-Gi Jung and his research team at the Center for Energy Storage Research of the Korea Institute of Science and Technology (KIST, President Lee Byung Gwon) have announced the development of silicon anode materials that can increase battery capacity four-fold in comparison to graphite anode materials and enable rapid charging to more than 80% capacity in only five minutes. When applied to batteries for electric vehicles, the new materials are expected to more than double their driving range.
A team of scientists from the Hybrid Photonics Laboratory at the Skolkovo Institute of Science and Technology (Skoltech) and the University of Sheffield (UK) made a breakthrough in understanding nonlinear physics of the strong interaction of organic molecules with light. Principles of strong light matter interaction open new horizons of ultra-fast and low energy all-optical data processing. The findings were published in Communications Physics and featured in the February issue of Nature Physics. The study was partially supported by Russian Science Foundation (RSF).
Researchers have reported a black phosphorus transistor that can be used as an alternative ultra-low power switch. A research team led by Professor Sungjae Cho in the KAIST Department of Physics developed a thickness-controlled black phosphorous tunnel field-effect transistor (TFET) that shows 10-times lower switching power consumption as well as 10,000-times lower standby power consumption than conventional complementary metal-oxide-semiconductor (CMOS) transistors.
Permafrost in the soil and methane hydrates deep in the ocean are large reservoirs of ancient carbon. As soil and ocean temperatures rise, the reservoirs have the potential to break down, releasing enormous quantities of the potent greenhouse gas methane. But would this methane actually make it to the atmosphere?
Due to the disappearance of its sunlight-reflecting seasonal snowpack, the Colorado River Basin is losing more water to evaporation than can be replaced by precipitation, researchers report. The study resolves a longstanding disagreement in previous estimates of the river's sensitivity to rising temperatures and identifies a growing potential for severe water shortages in this major basin. The Colorado River, a water source that supplies water to roughly 40 million people and supports more than $1 trillion of economic activity each year, is dwindling.
The atmospheric release of ancient stores of methane in thawing permafrost or from beneath Arctic ice may not impact future climate warming as strongly as previously believed, a new study finds. Rather, emissions of the greenhouse gas from current activities are more important for our immediate future. Methane (CH4) is a potent greenhouse gas with a global warming potential many times more powerful than carbon dioxide. Currently, natural emissions account for nearly 40% of total CH4 emissions.
New York, NY--February 20, 2020--Two-dimensional materials from layered van der Waals (vdW) crystals hold great promise for electronic, optoelectronic, and quantum devices, but making/manufacturing them has been limited by the lack of high-throughput techniques for exfoliating single-crystal monolayers with sufficient size and high quality.
Ultraviolet (UV) technology developed by the New York-based firm PurpleSun Inc. eliminates more than 96 percent of pathogens in operating rooms (ORs) and on medical equipment, compared to 38 percent using manual cleaning methods that rely on chemicals to disinfect surfaces, according to a study published this month in the American Journal of Infection Control (AJIC).
LOS ANGELES, Feb. 20, 2020 -- A non-invasive, wearable, magnetic brain stimulation device could improve motor function in stroke patients, according to preliminary late breaking science presented today at the American Stroke Association's International Stroke Conference 2020. The conference, Feb. 19-21 in Los Angeles, is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.
ITHACA, N.Y. - Cornell University researchers have found a new species of soil bacteria that is particularly adept at breaking down organic matter, including the cancer-causing chemicals that are released when coal, gas, oil and refuse are burned.
Dan Buckley, professor of microbial ecology and five other Cornell researchers, along with colleagues from Lycoming College, described the new bacterium in a paper published in the International Journal of Systematic and Evolutionary Microbiology.
Researchers said the wavelengths at sunrise and sunset have the biggest impact to brain centers that regulate our circadian clock and our mood and alertness.
Their study, "A color vision circuit for non-image-forming vision in the primate retina," published in Current Biology Feb. 20, identifies a cell in the retina, which plays an important role in signaling our brain centers that regulate circadian rhythms, boost alertness, help memory and cognitive function, and elevate mood.
Tokyo, Japan - Researchers at the Institute of Industrial Science, a part of The University of Tokyo, have developed a new procedure for recycling concrete with the addition of discarded wood. They found that the correct proportion of inputs can yield a new building material with a bending strength superior to that of the original concrete. This research may help drastically reduce construction costs, as well as slash carbon emissions.
A positive example set by both the mother and the father promotes the consumption of vegetables, fruit and berries among 3-5-year-old children, according to a new study from the University of Eastern Finland. The study explored the association of the home food environment and parental influence with the consumption of vegetables among kindergarten-aged children. The findings were published in Food Quality and Preference.
A "quiet" revolution in unregulated areas of the internet has led to the emergence of a new private security industry, according to latest research from the University of Portsmouth.
Often described as the "new wild west", criminals see new opportunities online, with this latest study showing how individuals and organisations are now taking the law into their own hands in order to protect themselves.
