Smoke from the many wildfires burning in the West have made air quality hazardous for millions of people in the United States. And it is the very tiniest of the aerosol particles in that air that make it particularly harmful to human health. But for decades, we haven't known how long these particles actually stay aloft.
New research by Colorado State University scientists is giving us a much better understanding of this process, which can help not only in air quality forecasting, but also in global climate modeling.
Expanding routine newborn screening to include a metabolic vulnerability profile could lead to earlier detection of life-threatening complications in babies born preterm, according to a study by UC San Francisco researchers. The new method, which was developed at UCSF, offers valuable and time-sensitive insights into which infants are at greatest risk during their most vulnerable time, immediately after birth.
MISSOULA - University of Montana researchers have contributed to a study forecasting significant ice loss in Greenland. According to the study just published in the journal Nature, Greenland will lose more ice this century than in the past 12,000 years if greenhouse gas emissions are not curbed.
Through a multiorganizational collaboration, the study brought together climate modelers, ice core scientists, remote sensing experts and paleoclimate researchers.
NASA's Aqua satellite analyzed the large Tropical Storm Chan-hom as it tracked through the Northwestern Pacific Ocean. Aqua imagery showed the storm was consolidating, indicating a strengthening trend.
One of the ways NASA researches tropical cyclones is using infrared data that provides temperature information. The AIRS instrument aboard NASA's Aqua satellite captured a look at those temperatures in Chan-hom and gave insight into the size of the storm and its rainfall potential.
Philadelphia, October 7, 2020 - With a steady growth in online grocery shopping, a new study in the Journal of Nutrition Education and Behavior, published by Elsevier, examines the availability of nutrition-related information on leading grocery store websites.
An analysis of published studies has found a relatively high prevalence of suicidal behaviors among physicians. The findings are published in Suicide and Life-Threatening Behavior.
A new review published in the Journal of Research in Science Teaching highlights the potential of machine learning--a subset of artificial intelligence--in science education. Although the authors initiated their review before the COVID-19 outbreak, the pandemic highlights the need to examine cutting-edge digital technologies as we re-think the future of teaching and learning.
From ants to primates, 'Napoleonic' intelligence has evolved to help animals contend with the myriad cognitive challenges arising from interactions with rival outsiders, suggest researchers at the University of Bristol in a paper published in Nature Communications today [Tuesday 6 October].
Antagonistic and co-operative social interactions within groups have long been suggested to drive the evolution of big brains. But animals from across the social spectrum must constantly juggle threats and opportunities from outsiders too.
Training parents of children with autism spectrum disorder virtually about early behavioral intervention is an accessible and effective approach during the coronavirus pandemic or in other instances when in-person instruction is not possible, according to a Rutgers researcher.
The study, which was published in The Journal of Applied Behavioral Analysis, broadens the treatment options for parents of children with autism who lack access to in-person training as they do now during the coronavirus pandemic.
BUFFALO, N.Y. - An analysis by a University at Buffalo-led team using two estimates of undocumented immigration suggests that, on average, this population reduced or had no effect on crime in 154 U.S. metropolitan areas studied, including places such as New York City, Chicago and Las Vegas.
A new study examining the link between peanut and tree-nut anaphylaxis in children and holidays found spikes at Halloween and Easter. The study, led by a team of researchers from the Montreal Children's Hospital of the McGill University Health Centre (MCH-MUHC), found that most were previously unknown allergies, calling for increased awareness.
The death of neurons, whether in the brain or the eye, can result in a number of human neurodegenerative disorders, from blindness to Parkinson's disease. Current treatments for these disorders can only slow the progression of the illness, because once a neuron dies, it cannot be replaced.
Biotechnologists from MIPT have developed a method for extracting the active constituents from the fat of black soldier fly larvae. These compounds possess unique antimicrobial properties and can destroy bacteria that cause farm crop diseases and are resistant to antibiotics. The study was published in Microorganisms.
With intense wildfires in the western U.S. and frequent, intense hurricanes in the Gulf of Mexico, the nation is again affected by extreme weather-related events resulting from climate change. In response, cities, states and regions across the country are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many state and local governments are committed to these goals, however, the emissions data they have to work with is often too general and too expensive to provide a useful baseline and target the most effective policy.
NASA's Aqua satellite analyzed Tropical Storm Delta in infrared imagery as it moved through the Caribbean Sea. The imagery provided cloud top temperatures to identify the strongest areas within the storm.
Potential Tropical Cyclone 26 formed in the Caribbean Sea on Sunday, Oct. 4 by 5 p.m. EDT. Six hours later, the National Hurricane Center (NHC) classified it as Tropical Depression 26. By 8 a.m. EDT, satellite imagery helped confirm that the depression had strengthened into a tropical storm. At that time, it was given the name Delta.
