COLUMBIA, Mo. -- Sticking with an exercise program can be tough, even during the best of times. But what about during a pandemic? A new study by the University of Missouri and Oklahoma State University found that even when gyms were closed and there were other COVID-19 restrictions limiting face-to-face meetings, older adults who completed the Stay Strong, Stay Healthy exercise program — created at MU in 2005 — continued to maintain long-term exercise habits independently, which resulted in improved lifestyle changes and an increase in both physical energy and self-confidence. “We ...

People with a recent diagnosis of atrial fibrillation (AF), the most common irregular heart rhythm, have a modestly higher risk of developing dementia than people without the condition, according to research published today. “Previous studies that have examined the link between atrial fibrillation and dementia have yielded conflicting results, and we hope that our study’s large sample size helps to establish confidence in our findings,” said Dr. Nisha Bansal, a professor of medicine at the University of Washington School of Medicine. “The study also included a community based, diverse population, which may increase the generalizability ...

UPTON, NY—Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are leading a new effort to land a radio telescope on the moon. If successful, the project will mark the first step towards exploring the Dark Ages of the universe. The Dark Ages are an early era of cosmological history starting about 380,000 years after the Big Bang. There were no stars or planets in the Dark Ages. It’s a point in time that scientists have never been able to observe. Though radio waves from the Dark Ages still linger in space, the abundance of radio interference on Earth has masked these signals from scientists seeking to study them. If ...

A new study shows for the first time a connection between a mitochondrial metabolite and the activation of an inflammatory response. Mitochondria are functional units of our cells that fulfil important tasks, i.e. chemical reactions, for the functioning of the cell. One of these tasks is the production of energy that is necessary for cell growth and reproduction. If certain chemical reactions in the mitochondrion change, diseases occur. For example, deficiencies in fumarate hydratase (FH) in the Krebs cycle, one of the most important metabolic pathways in mitochondria, ...

March 8, 2023 – Previous studies have reported high rates of death by suicide and drug overdose – including opioid overdose – in military service members with a history of mild traumatic brain injury (mTBI). A new study finds that those risks are highest among military members with mTBI who identify their racial/ethnic status as "Other," as opposed to standard racial/ethnic categories, reports the March/April issue of the Journal of Head Trauma Rehabilitation (JHTR). The official journal of the Brain Injury Association of America, JHTR is ...

Nearly two dozen experimental therapies targeting the immune system are in clinical trials for Alzheimer’s disease, a reflection of the growing recognition that immune processes play a key role in driving the brain damage that leads to confusion, memory loss and other debilitating symptoms. Many of the immunity-focused Alzheimer’s drugs under development are aimed at microglia, the brain’s resident immune cells, which can injure brain tissue if they’re activated at the wrong time or in the wrong way. A new study from researchers at Washington University School of Medicine in St. Louis ...

About The Study: Researchers found in this examination of newborn drug testing at a Midwestern academic medical center before and after statewide legalization of recreational cannabis that clinicians ordered newborn drug tests more frequently for Black newborns when no drug testing was done during pregnancy. These findings call for further exploration of how structural and institutional racism contribute to disproportionate testing and subsequent Child Protective Services investigation, surveillance, and criminalization of Black parents.  Authors: Lauren Oshman, M.D., M.P.H., of the University of Michigan ...

The Bakken Shale Formation—a 200,000-square-mile shale deposit below parts of Canada and North Dakota—has supplied billions of barrels of oil and natural gas to North America for 70 years. A new discovery reveals that the rocks also open a uniquely informative window into Earth’s complicated geological history. A research team, which included geologists from the University of Maryland, George Mason University and the Norwegian oil and gas company Equinor, developed a new framework for analyzing paleontological and biogeochemical data extracted from the formation’s rock. Using this technique, the team pinpointed a major trigger of several closely spaced ...

New insights into the effects of a hormonal treatment for transgender men, discovered by Cedars-Sinai investigators, could have implications for the treatment of breast cancer.  Transgender men who were assigned female at birth and identify today as male may take hormones called androgens to induce physical changes that help them align their physical appearance with their identified gender. Androgens such as testosterone are involved primarily in the development of male traits, although females also produce androgens.  Molecular changes observed in the breast tissue of transgender men undergoing androgen therapy may signal the potential ...

At a glance: A small population of airway neurons alerts the brain about a flu infection, according to a new study in mice The results help explain how drugs like ibuprofen and aspirin reduce flu symptoms The findings could help scientists develop more-effective flu therapies A new study led by researchers at Harvard Medical School illuminates how the brain becomes aware that there is an infection in the body. Studying mice, the team discovered that a small group of neurons in the airway plays a pivotal role in alerting the brain about ...

Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water being inherited into a protoplanetary disk without significant changes to its composition. These results further suggest that the water in our Solar System formed billions of years before the Sun. The new observations are published today in Nature. V883 Orionis is a protostar located roughly 1,305 light-years from Earth in the constellation Orion. ...

ANN ARBOR, Mich. – If a newborn tests positive for certain drugs after birth, mandated reporters in many states – including health care professionals and social workers – are required to report it to Child Protective Services. But guidelines on what should trigger these tests are often unclear and inconsistent, which studies have shown may contribute to racial inequities in who gets tested. Residents, faculty, medical students and researchers at Michigan Medicine’s Department of Family Medicine and Antiracism and Health Equity Program wanted to determine rates of newborn drug testing and if these rates varied by ...

EMBARGOED UNTIL 11:00 AM EST Wednesday, March 8, 2023 Contact: Jillian McKoy, jpmckoy@bu.edu Michael Saunders, msaunder@bu.edu ## Gun violence—and racial disparities in gun violence—have increased substantially during the pandemic, particularly among children. Now a new study led by a Boston University School of Public Health (BUSPH) researcher shows just how stark these differences in risk of firearm injury are between White and non-White children. Published as a research letter in JAMA Network Open, the study examined gun injuries among children in four major US cities—New York City, Chicago, Los Angeles, and Philadelphia—and ...

Rice is one of the most important crops in the world and constitutes the primary food source for over half of Earth’s population. Protecting rice plantations from disease is therefore an essential endeavor in modern agriculture. Of the many pathogens that can infect rice plants, the bacterium Xanthomonas oryzae, which is responsible for bacterial blight (BB), is among the worst. Hundreds of millions of dollars’ worth of crops are lost each year due to BB, and millions of dollars are spent in preventive measures and research. One of the most fruitful strategies to control BB and other crop diseases is to grow genetically resistant cultivars. However, as pathogens can ...

BOSTON – Mass General researchers have discovered a novel molecular mechanism responsible for the most common forms of acquired hydrocephalus, potentially opening the door to the first-ever nonsurgical treatment for a life-threatening disease that affects about a million Americans. As reported in the journal Cell, the team uncovered in animal models the pathway through which infection or bleeding in the brain triggers a massive neuroinflammatory response that results in increased production of cerebrospinal fluid (CSF) ...

About The Study: Child firearm assaults increased substantially during the COVID-19 pandemic in four major U.S. cities, according to the results of this study.

The link between symptoms of COVID-19 and physical inactivity is increasingly evident. An article recently published in the journal Scientific Reports by researchers at the University of São Paulo (USP) in Brazil describes a study in which COVID-19 survivors with at least one persistent symptom of the disease were 57% more likely to be sedentary, and the presence of five or more post-acute sequelae of infection by SARS-CoV-2 increased the odds of physical inactivity by 138%. “Although this was a cross-sectional study, the findings underscore the importance of discussing and encouraging physical activity at all times, including during the pandemic,” ...

Mezcal is a distilled alcohol made from the boiled and fermented sap of agave plants. Most mezcal beverages — including all brands of tequila — are sold as pure distillates, but a few have an added stowaway bottled inside: worms.   Called gusanos de maguey (Spanish for agave worms), these odd organic chasers aren’t actually worms, but instead a type of insect larva, and their addition to mezcal is a recent one. Mezcal production has a storied history, dating back to the first Spanish inhabitants of Mexico, but larvae were only added to the drink in ...
