Simply wearing a mask may not be enough to prevent the spread of COVID-19 without social distancing. In Physics of Fluids, by AIP Publishing, researchers tested how five different types of mask materials impacted the spread of droplets that carry the coronavirus when we cough or sneeze. Each of the masks captured the vast majority […]
Substances present in cooked meats are associated with increased wheezing in children, Mount Sinai researchers report. Their study, published in Thorax, highlights pro-inflammatory compounds called advanced glycation end-products (AGEs) as an example of early dietary risk factors that may have broad clinical and public health implications for the prevention of inflammatory airway disease. Researchers examined […]
Discovering wide variation in hospitals’ COVID-19 survival rates, researchers found that the levels of COVID-19 in the surrounding community was likely the driving factor. High rates of COVID-19 in the county where a hospital is located appears to reduce survival rates among hospitalized patients with the virus, according to a new study from researchers in […]
Seasonal changes in UV may alter the spread of COVID-19 but not as much as social distancing. Natural variations in ultraviolet radiation influence the spread of COVID-19, but the influence is modest compared to preventive measures such as physical distancing, mask wearing, and quarantine, according to new research from Harvard University. Analyzing daily COVID-19 and […]
Having hope for the future could protect people from risky behaviors such as drinking and gambling – according to new research from the University of East Anglia. Researchers studied ‘relative deprivation’ – the feeling that other people have things better than you in life. They wanted to find out why only some people experiencing this […]
Genetic evidence is second only to clinical trials as a way to tell which treatments will be effective in a disease. Existing drugs that target the actions of the genes reveal which drugs should be repurposed to treat Covid-19 in clinical trials, experts say. Genes involved in two molecular processes – antiviral immunity and lung […]
More and more evidence is coming out that people with COVID-19 are suffering from cognitive effects, such as brain fog and fatigue. And researchers are discovering why. The SARS-CoV-2 virus, like many viruses before it, is bad news for the brain. In a study published Dec.16 in Nature Neuroscience, researchers found that the spike protein, […]
Young people who prefer to stay up late are more impulsive than their peers who go to bed earlier, which makes them more likely to drink alcohol and smoke, a new study in the journal Chronobiology International, reports. In the first study of its kind, researchers from the University of Surrey and Brunel University London […]
Computational simulations have been used to accurately predict airflow and droplet dispersal patterns in situations where COVID-19 might be spread. In the journal Physics of Fluids, by AIP Publishing, results show the importance of the shape of the space in modeling how virus-laden droplets move through the air. The cough-generated droplets from a walking individual […]
Dental procedures can pose a high risk of viral transmission because the tools that are used often produce aerosols, which can contain high numbers of Coronavirus. The aerosols are generated when saliva mixes with water and air streams used in dental procedures. As a result, access to routine dentistry continues to be limited during the […]
