COLLEGE PARK, Md. - Anxiety, the most common family of mental illnesses in the U.S., has been pushed to epic new heights by the COVID-19 pandemic, with the Centers for Disease Control and Prevention estimating that nearly 1 in 3 U.S. adults and a staggering 41% of people ages 18-29 experienced clinically significant anxiety symptoms in late August. Now, the findings of a recent UMD-led study indicate that some long-accepted thinking about the basic neuroscience of anxiety is wrong.
Talking to people at gun shows about suicide prevention and the risks of unsecured firearms can lead to safe weapons storage, according to a new study.
The research by Forefront Suicide Prevention at the University of Washington, from visits to 18 gun shows and other community events around Washington state last year, found that engaging people in a community-based setting, in an empathetic conversation focused on safety, resulted in more people locking up their firearms.
PULLMAN, Wash. - People with obsessive-compulsive disorder, or OCD, report that the severity of their symptoms was reduced by about half within four hours of smoking cannabis, according to a Washington State University study.
PITTSBURGH, Oct. 19, 2020 - Older people who report greater levels of social engagement have more robust gray matter in regions of the brain relevant in dementia, according to new research led by scientists at the University of Pittsburgh Graduate School of Public Health. It is the first to use a particularly sensitive type of brain imaging to conduct such an evaluation.
CHAMPAIGN, Ill. -- Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB. Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.
The findings appear in the journal Scientific Reports.
Transportation is the top source of greenhouse gas emissions in the United States, accounting for almost 30 percent of total emissions. In the national and global effort to reduce emissions and mitigate climate change, electric vehicles (EVs) provide an attractive option. But despite dropping prices and rising popularity, EVs continue to make up a small percentage of the automotive industry's market share.
Any Red Sea diver will have encountered colorful triggerfish along coral reefs, and some divers will have experienced the painful bite of their huge teeth if they get too close to their nesting grounds. Now, Ph.D. student Matthew Tietbohl and colleagues at KAUST report a peculiar feeding strategy by a titan triggerfish that highlights their innate ability to learn and adapt.
Ants are one of the most successful groups of animals on the planet, occupying anywhere from temperate soil to tropical rainforests, desert dunes and kitchen counters. They're social insects and their team-working abilities have long since been identified as one of the key factors leading to their success. Ants are famously able to lift or drag objects many times their own weight and transport these objects back to their colony. But with previous research having focused on the social aspects of an ant colony, looking at an individual ant has been somewhat neglected.
Beijing, China 19 Oct 2020: Elevated birth weight is linked with developing atrial fibrillation later in life, according to research presented at the 31st Great Wall International Congress of Cardiology (GW-ICC).
GW-ICC 2020 is a virtual meeting during 19 to 25 October. Faculty from the European Society of Cardiology (ESC) will participate in joint scientific sessions with the GW-ICC as part of the ESC Global Activities programme.
All modern life uses energy to reproduce itself. During this process, organisms build and break down larger molecules such as fats and sugars using a remarkably common set of reactive intermediate energy carrier molecules. These intermediate energy carriers (for example ATP) are often not building blocks in and of themselves, but they allow the energy coupling between separate reactions needed to push forward cellular reproduction. One class of these compounds are thioesters, chemical compounds that contain a high-energy carbon-sulfur bond.
One way CBD appears to reduce the "cytokine storm" that damages the lungs and kills many patients with COVID-19 is by enabling an increase in levels of a natural peptide called apelin, which is known to reduce inflammation and whose levels are dramatically reduced in the face of this storm.
Dental College of Georgia and Medical College of Georgia researchers reported this summer CBD's ability to improve oxygen levels and reduce inflammation as well as physical lung damage in their laboratory model of deadly adult respiratory distress syndrome, or ARDS.
PHILADELPHIA (October 12, 2020) - Smell loss is a frequently reported symptom of COVID-19 but reports of prevalence vary from study-to-study and range from 5% to 98%. With such a wide range of estimates, it is difficult to prioritize its importance for testing and treatment.
Droplets of fat inside our cells are helping the body's own defence system fight back against infection, University of Queensland researchers have discovered.
LA JOLLA--Your pancreas is studded with cell clusters called islets. In most people, special beta cells live snug in the islets, happily making the insulin that the body uses to regulate blood sugar. But in people with type 1 diabetes, the body's T cells mistakenly move into the islets and kill the beta cells.
New research suggests that conditions such as attention deficit hyperactivity syndrome (ADHD), bipolar disorder, and even aggressive behaviors may be linked with sugar intake, and that it may have an evolutionary basis.
The research, out today from the University of Colorado Anschutz Medical Campus and published in Evolution and Human Behavior, presents a hypothesis supporting a role for fructose, a component of sugar and high fructose corn syrup, and uric acid (a fructose metabolite), in increasing the risk for these behavioral disorders.
