On Friday September 4, 2020 at about 6:44 PM PDT the Creek Fire began in the Big Creek drainage area between Shaver Lake, Big Creek and Huntington Lake, Calif. NASA's Suomi NPP satellite captured these images of the fire on Sep. 05 through Sep. 07, 2020. From the series of images the spread of the fire can be seen in the outward movement of the red hot spots, although the huge cloud on the 6th obscures all readings due to its size.
Researchers at Princeton University have created a new and improved way to more precisely control genetically engineered bacteria: by simply switching the lights on and off. Working in E. coli, the workhorse organism for scientists to engineer metabolism, researchers developed a system for controlling one of the key genetic circuits needed to turn bacteria into chemical factories that produce valuable compounds such as the biofuel isobutanol.
In a new review paper by the University of Vienna, Imperial College London, and RMIT University in Australia, researchers argue that leather made from fungi has "considerable potential" to be the best leather substitute in terms of sustainability and cost when compared to animal and plastic-derived versions.
Amsterdam, September 7, 2020 - A recent study by a team based at the University of Bologna, published in the Journal of Archaeological Science, has shed new light on the Minoan system of fractions, one of the outstanding enigmas tied to the ancient writing of numbers.
Tohoku University Professor Taiichi Otsuji has led a team of international researchers in successfully demonstrating a room-temperature coherent amplification of terahertz (THz) radiation in graphene, electrically driven by a dry cell battery.
WASHINGTON, September 8, 2020 -- N95 masks are a critical part of the personal protective equipment used by front-line health care workers. These masks achieve 95% efficiency at filtering out tiny 0.3-micron particles, while maintaining reasonable breathability, thanks to a layer of fine melt-blown polypropylene fibers incorporating electrical charges to attract particles.
Extended usage and decontamination provoked by severe supply shortages around the globe during the COVID-19 pandemic can easily remove the charges and degrade filtration efficiency.
Restoring normal patterns of rhythmic neural activity through non-invasive electrical stimulation of the brain alleviates sound-processing deficits and improves reading accuracy in adults with dyslexia, according to a study published September 8, 2020 in the open-access journal PLOS Biology by Silvia Marchesotti and Anne-Lise Giraud of the University of Geneva, and colleagues.
What The Study Did: Survey data were used to assess changes in the use of electronic cigarettes among U.S. adults from 2016 to 2018.
Authors: Michael J. Blaha, M.D., M.P.H., of the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease in Baltimore, is the corresponding author.

The use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and diclofenac, is not associated with any adverse effects in people who have tested positive for COVID-19, according to a new study published September 8 in PLOS Medicine by Anton Pottegård of the University of Southern Denmark and colleagues from Aarhus University Hospital and the Danish Medicines Agency.
The joint research team of RIKEN and Hokkaido University developed a method to predict rate constants of reverse intersystem crossing (RISC)(1) associated with light emission efficiency of organic semiconductors used for Organic Light-Emitting Diode (OLED)(2) through quantum chemical calculations with computers.
Scientists at UBC are unravelling the mysteries behind a persistent problem in commercial beekeeping that is one of the leading causes of colony mortality--queen bee failure.
This occurs when the queen fails to produce enough fertilized eggs to maintain the hive, and is regularly cited by the Canadian Association of Professional Apiarists as one of the top causes of colony mortality.
As exploitation of wild fisheries and marine environments threaten food supplies, Flinders University scientists are finding sustainable new ways to convert biowaste, algal biomass and even beached seaweed into valuable dietary proteins and other products.
In one of several projects under way at the Flinders Centre for Marine Bioproducts Development, researchers are looking to extract value from crayfish shells and other marine waste via a 'green' fluidic processing machine developed at the University.
The significant reduction in vehicle journeys during the COVID-19 lockdown did not reduce the level of toxic fine particles in Scotland's air, according to experts at the University of Stirling.
Analysis of fine particulate air pollution (PM2.5) in the first month of restrictions found little change - despite a 65 per cent reduction in the number of vehicles on the country's roads.
Skoltech scientists and their colleagues from Lomonosov Moscow State University (MSU) have developed a new method of silicon recycling. Their research was published in ACS Sustainable Chemistry & Engineering.
Semiconductor manufacturers are paying more attention to two-dimensional materials, such as transition metal dichalcogenides (TMDs), following the discovery, at KAUST, of an epitaxial growth process of single-crystal TMDs nanoribbons.
