New review explores effective sampling techniques for collecting airborne viruses and ultrafine part
As the world continues to grapple with the COVID-19 pandemic, an international team of researchers have published a review of the best techniques to collect airborne aerosols containing viruses.
In the review, which was published by the Science of the Total Environment journal, a team led by the University of Surrey concluded that the most effective way to collect and detect airborne pathogens, particularly viruses, was to use cyclone sampling techniques.
The Cabeza de los Gatos waste rock pile, left from mining activities in the town of Tharsis (Huelva), underwent a rehabilitation process consisting of remodelling the slope of the pile, applying liming materials and then a layer of soil. Finally, trees and shrubs typical of the area were planted and a hydroseeding with a mixture of shrub and herbaceous seeds was applied.
In asthma, the airways become hyperresponsive. Researchers from Uppsala University have found a new mechanism that contributes to, and explains, airway hyperresponsiveness. The results are published in the scientific journal Allergy.
Some 10 per cent of Sweden's population suffer from asthma. In asthmatics, the airways are hyperresponsive (overreactive) to various types of stimuli, such as cold air, physical exertion and chemicals. The airways become constricted, making breathing difficult.
Scientists have long theorized that supermassive black holes can wander through space--but catching them in the act has proven difficult.
Now, researchers at the Center for Astrophysics | Harvard & Smithsonian have identified the clearest case to date of a supermassive black hole in motion. Their results are published today in the Astrophysical Journal.
Since the pandemic hit, researchers have been uncovering ways COVID-19 impacts other parts of the body, besides the lungs.
Now, for the first time, a visual correlation has been found between the severity of the disease in the lungs using CT scans and the severity of effects on patient's brains, using MRI scans. This research is published in the American Journal of Neuroradiology. It will be presented at the 59th annual meeting of the American Society of Neuroradiology (ASNR) and has also been selected as a semifinalist for that organization's Cornelius Dyke Award.
As the driver of global atmospheric and ocean circulation, the tropics play a central role in understanding past and future climate change. Both global climate simulations and worldwide ocean temperature reconstructions indicate that the cooling in the tropics during the last cold period, which began about 115,000 years ago, was much weaker than in the temperate zone and the polar regions.
Arlington, Va. (March 12, 2021)--A new supplement offering guidance on severe COVID-19 management in resource-limited settings is now available on the American Journal of Tropical Medicine (AJTMH) website.
Reston, VA--Immuno-positron emission tomography (PET) imaging can provide early insight into a tumor's response to targeted therapy, allowing physicians to select the most effective treatment for patients who have cancer. The new research was published in the March issue of The Journal of Nuclear Medicine.
A new study by UC Davis MIND Institute researchers suggests that executive control differences in autism spectrum disorder (ASD) may be the result of a unique approach, rather than an impairment.
March 12, 2021 - Financial strains like debt or unemployment are significant risk factors for becoming homeless, and even help to explain increased risk of homelessness associated with severe mental illness, reports a study in a supplement to the April issue of Medical Care.
Informing how COVID-19 response plans may incorporate digital contact tracing, a model of COVID-19 spread within a simulated French population found that if about 20% of the population adopted a contact tracing app on their smartphones, an outbreak could be reduced by about 35%. If more than 30% of the population adopted the app, the epidemic could be suppressed to manageable levels.
DURHAM, N.C. -- If you binged on high-calorie snacks and then spent the winter crashed on the couch in a months-long food coma, you'd likely wake up worse for wear. Unless you happen to be a fat-tailed dwarf lemur.
This squirrel-sized primate lives in the forests of Madagascar, where it spends up to seven months each year mostly motionless and chilling, using the minimum energy necessary to withstand the winter. While zonked, it lives off of fat stored in its tail.
Decades of feminist gains in the workforce have been undermined by the COVID-19 pandemic, which has upended public education across the United States, a critical infrastructure of care that parents -- especially mothers -- depend on to work, according to new research from Washington University in St. Louis.
A study of the relationship between temperature and yields of various rice varieties, based on 50 years of weather and rice-yield data from farms in the Philippines, suggests that warming temperatures negatively affect rice yields.
The Affordable Care Act (ACA) dramatically increased children's preventive healthcare while reducing out-of-pocket costs, according to a new Boston University School of Public Health (BUSPH) study.
Published in JAMA Network Open, the study found that checkups with out-of-pocket costs dropped from 54.2% of visits in 2010 (the year the ACA passed) to 14.5% in 2018.
"This is a great feather in the cap of the ACA, even though there is still some work to do," says study lead author Dr. Paul Shafer, assistant professor of health law, policy & management at BUSPH.
