UNIVERSITY PARK, Pa. -- The rate of suicide among post-9/11 military veterans has been rising for nearly a decade. While there are a number of factors associated with suicide, veterans have unique experiences that may contribute to them thinking about killing themselves.
Amsterdam, March 1, 2021 - Comfort is a daily human experience central to the perception of our environment and the continuous processing of sensory input. Environmental factors such as smell, temperature and light can influence comfort, as can our interaction with products, such as the design of a chair or a mattress. Increasingly, researchers investigating the science of comfort and discomfort are focusing on the role of human behavior.
Scientists have identified that the COVID-19 virus could be transmitted through faecal contaminated river water.
A team of researchers, including water quality, epidemiology, remote sensing and modelling experts, led by Dr Jamie Shutler at the University of Exeter, have developed a fast and simple way to assess the potential risk of water-borne transmission of the COVID-19 virus, posed by sewage spills into open and closed freshwater networks.
The anti-inflammatory drug hydroxychloroquine should not be used to prevent infection in people who do not have covid-19, say a WHO Guideline Development Group (GDG) panel of international experts in The BMJ today.
Their strong recommendation is based on high certainty evidence from six randomised controlled trials involving over 6,000 participants with and without known exposure to a person with covid-19 infection.
Philadelphia, Pa. -- More than one out of every 10 seniors (10.5%) enrolled in a Medicare Advantage plan, also known as a Medicare managed care option, and living in a rural area, switched to traditional Medicare during 2010-2016. The switch was driven primarily due to low satisfaction with care access, according to a study published this week in Health Affairs from researchers at Drexel University's Dornsife School of Public Health. By contrast, only 1.7% of rural traditional Medicare enrollees made the switch to Medicare Advantage during this period.
CHICAGO --- Public attitude toward COVID-19 and its treatments is more "infectious" than the disease itself, according to a new Northwestern Medicine study using Artificial Intelligence (AI) to analyze tweets about the virus. Researchers studied the influence of Twitter on COVID-19 health beliefs as well as the competing influence of scientific evidence versus the speeches of politicians.
The study's key findings:
DURHAM, N.C. - Anyone who has ever developed a urinary tract infection (UTI) knows that it can be painful, pesky and persistent. UTIs have a high recurrence rate and primarily afflict women -- as many as 50% of women will experience at least one UTI during their lifetime.
However, what if patients could take a vaccine that would prevent future UTIs? In a March 1 study in the Proceedings of the National Academy of Sciences, Duke researchers describe a new vaccination strategy that they think could re-program the body to fight off the bacteria that cause urinary tract infections.
Scientists from Far Eastern Federal University (FEFU) together with Russian and German colleagues, continue studying antitumor compounds synthesized based on bioactive molecules isolated from a sea sponge. One of them fights cancer cells resistant to standard chemotherapy, and at the same time has an interesting dual mechanism of action. A related article appears in Marine Drugs.
SILVER SPRING, Md. - A recent preclinical study by U.S. Military HIV Research Program (MHRP) researchers showed that an experimental therapy combining a TLR7 agonist and two broadly neutralizing antibodies delayed viral rebound in SHIV-infected macaques after antiretroviral therapy (ART) interruption.
NEW YORK, NY (March 1, 2021)--By harnessing the immune system against cancer, immunotherapies have revolutionized the way some types of cancer are treated. But most patients--across cancer types--do not respond, and in most cases, scientists are at a loss as to why.
Researchers at Columbia and MIT have created a new technique that can uncover nearly all of the tricks cancer cells use to evade immunotherapies, which could lead to the development of more effective treatments.
Tissue engineering has long-depended on geometrically static scaffolds seeded with cells in the lab to create new tissues and even organs. The scaffolding material -- usually a biodegradable polymer structure -- is supplied with cells and the cells, if supplied with the right nutrients, then develop into tissue as the underlying scaffold biodegrades. But this model ignores the extraordinarily dynamic morphological processes that underlie the natural development of tissues.
A team of international researchers led by a Florida State University assistant professor has analyzed reams of data from the Neolithic to Late Roman period looking at migration patterns across the Mediterranean and found that despite evidence of cultural connections, there's little evidence of massive migration across the region.
The human gut consists of a complex community of microbes that consume and secrete hundreds of small molecules--a phenomenon called cross-feeding. However, it is challenging to study these processes experimentally. A new study, published in Nature Communications, uses models to predict cross-feeding interactions between microbial species in the gut. Predictions from such computational methods could eventually help doctors get a more complete understanding of gut health.
Researchers from Skoltech and the University of Cambridge have shown that polaritons, the quirky particles that may end up running the quantum supercomputers of the future, can form structures behaving like molecules - and these "artificial molecules" can potentially be engineered on demand. The paper outlining these results was published in the journal Physical Review B Letters.
A group of researchers representing four countries summed up the results of the Supertest, a large-scale study of the academic performance of engineering students in Russia, China, India, and the United States. It is the first study to track the progress of students in computer science and electrical engineering over the course of their studies with regard to their abilities in physics, mathematics, and critical thinking and compare the results among four countries.
