MADISON, Wis. -- As Americans begin pulling up their sleeves for an annual flu vaccine, researchers at the University of Wisconsin-Madison have provided new insights into an alternative vaccine approach that provides broader protection against seasonal influenza.
A group of social scientists who conduct cross-cultural research are casting a critical lens on their own practices.
Reno, Nev. (Sept. 22, 2020) - For people who suffer from asthma, wildfire smoke is more hazardous than other types of air pollution, according to a new study from the Desert Research Institute (DRI), the Renown Institute for Health Innovation (Renown IHI) and the Washoe County Health District (WCHD).
As the COVID-19 pandemic rages on, researchers are working overtime to develop vaccines and therapies to thwart SARS-CoV-2, the virus responsible for the disease Many efforts focus on the coronavirus spike protein, which binds the angiotensin-converting enzyme 2 (ACE2) on human cells to allow viral entry. Now, researchers reporting in ACS Central Science have uncovered an active role for glycans -- sugar molecules that can decorate proteins -- in this process, suggesting targets for vaccines and therapies.
PRICE, UTAH, USA - Some 92 to 66 million years ago, as the Age of Dinosaurs waned, giant marine lizards called mosasaurs roamed an ocean that covered North America from Utah to Missouri and Texas to the Yukon. The air-breathing predators were streamlined swimmers that devoured almost everything in their path, including fish, turtles, clams and even smaller mosasaurs.
Predatory bacteria, capable of invading and consuming harmful bugs such as E .coli and Salmonella, use a unique tool to help them escape the cell they have invaded without harming themselves, according to a new study.
Researchers at the Universities of Birmingham and Nottingham have identified a particular enzyme used by the bacteria to rupture the cell wall of its prey bacteria and exit without damaging its own cell wall. Their findings are published in Nature Communications.
Researchers at Karolinska Institutet have developed a method for fast, cheap, yet accurate testing for COVID-19 infection. The method simplifies and frees the testing from expensive reaction steps, enabling upscaling of the diagnostics. This makes the method particularly attractive for places and situations with limited resources. It is equally interesting for repeated testing and for moving resources from expensive diagnostics to other parts of the care chain. The study is published in Nature Communications.
Pale, male and stale - it's certainly stereotypical, but it's a saying that still holds water when it comes to Australian boards, according to new research from the University of South Australia.
Assessing the influence of gender diversity on Australian boards, researchers found that a persistent boys' club mentality is impairing decision-making at the top, particularly in relation to corporate social responsibility (CSR) initiatives.
Tsukuba, Japan - Thalidomide is a medication with several different effects, one of which is promoting sleep in the context of insomnia. In a new study, researchers from the University of Tsukuba have discovered that thalidomide exerts its hypnotic effects through mechanisms distinct from those for the drug's notorious teratogenicity.
Osaka, Japan — As the current COVID-19 crisis has shown, the disruptions that occur when transportation cannot proceed as usual are system-wide, affecting individual lives, companies, and the global economy. Now imagine a similar problem inside your brain and spinal cord.
Insomnia causing sleepless nights, daytime fatigue and poor health outcomes is a cycle worth busting, experts say, with depression, anxiety and stress a common co-occurrence.
A study of more than 450 insomnia patients in Australia has confirmed some positive results for such patients with insomnia.
The Flinders University researchers found not only that a program of targeted cognitive behavioural therapy for insomnia help relieve insomnia - but also has a positive effect on symptoms of depression, anxiety and stress.
Accumulation of assembled tau protein in the central nervous system is characteristic of Alzheimer's disease and several other neurodegenerative diseases, called tauopathies. Recent studies have revealed that propagation of assembled tau is key to understanding the pathological mechanisms of these diseases. Mouse models of tau propagation are established by injecting human-derived tau seeds intracerebrally; nevertheless, these have a limitation in terms of regulation of availability of human samples.
If sport is good for the body, it also seems to be good for the brain. By evaluating memory performance following a sport session, neuroscientists from the University of Geneva (UNIGE) demonstrate that an intensive physical exercise session as short as 15 minutes on a bicycle improves memory, including the acquisition of new motor skills. How? Through the action of endocanabinoids, molecules known to increase synaptic plasticity. This study, to be read in the journal Scientific Reports, highlights the virtues of sport for both health and education.
The small blood vessels in muscles of women after menopause are less able to grow compared to young women, according to new research published today in the Journal of Physiology. This means exercising before menopause is all the more important for women in order to develop blood vessels in muscles, and thus the ability to develop muscle strength.
A systematic review of evidence being presented at this week's ESCMID Conference on Coronavirus Disease shows that air around patients with COVID-19, as well as patients toilets, and staff and public areas in hospitals are all show significant levels of contamination with SARS-CoV-2. The study is by Dr Gabriel Birgand, University Hosptial Centre Nantes, France, and colleagues.
