BUFFALO, N.Y. – The science is clear that movement is good for our bodies as we age. But just how much physical activity is beneficial for people over 60? A new study from the University at Buffalo provides an answer, and it’s not 10,000 steps per day. In fact, the study — published Feb. 21 in JAMA Cardiology — of nearly 6,000 U.S. women aged 63-99 reports that, on average, 3,600 steps per day at a normal pace was associated with a 26% lower risk of developing heart failure. The observational study from the Women’s Health Initiative ...

The National Institutes of Health (NIH) has launched a clinical trials network to evaluate emerging technologies for cancer screening.

High-dose pressurized oxygen can stress out old immune cells, leaving behind a younger, better functioning immune system. It helped with acute COVID, and now Anders Kjellberg is testing the method for post-covid as well. Hyperbaric oxygen therapy, giving patients 100 percent oxygen at a pressure corresponding to 10-20 meters below sea level, has been around for almost 100 years. But the method lacks modern evidence from clinical studies, which also means that there is a lack of knowledge about dosage, all patients receive the same dose. "When I started my research, I wanted to find out how the treatment should be dosed to different patients," says ...

Most chronic wound infections share one thing in common: the presence of biofilms, which are composed of many different microorganisms that congregate as a mass, usually on some type of surface such as a wound bed. Biofilms are thought to be associated with up to 80% of infections, and their ability to stick together makes the biofilm and infection exceptionally difficult to kill. To combat this health care challenge, researchers such as Kendra Rumbaugh, Ph.D., a professor in the Texas Tech University Health Sciences Center (TTUHSC) School of Medicine’s Department of Surgery, are pursuing biofilm dispersal agents such as ...

Whales and dolphins get their nutrients and essential elements through their diet. While eating fish, squid, octopus, crustaceans and other marine mammals, they are also exposed to heavy metal contaminants. Elevated levels of toxins have been found in stranded dolphins and whales along the Southeastern Coast of the United States. Monitoring toxic contaminants in these stranded marine animals, which serve as important sentinels of environmental contamination, and whose health may be linked to human health, is vital. Yet, data remain sparse on how specific elements are distributed within an animal’s body, especially for many rarely encountered ...

Racially biased readings of oxygen levels in the blood using pulse oximeters may further limit opportunities for Black patients with heart failure to receive potentially lifesaving treatments, such as heart pumps and transplants, a Michigan Medicine study finds. “This is especially important because we know that Black patients are already less likely to receive heart pumps or transplants compared to their white counterparts, and these inaccurate readings can further widen a disparity that must be addressed by our health care system,” said first author Scott W. Ketcham, M.D., a third year ...

KANSAS CITY, MO—February 21, 2024—The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study from the Stowers Institute for Medical Research discovered that the hindbrain—the part of the brain controlling vital functions like blood pressure and heart rate—of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.  Research from the lab of Investigator Robb Krumlauf, Ph.D., published on February 20, 2024 in Nature Communications offers a glimpse into how the brains of ancient animals evolved. The team unexpectedly uncovered that ...

As part of the New Deal, several governmental programs were created to expand homeownership through mortgages and loans. However, neighborhoods with primarily Black or immigrant communities often were rated “hazardous” for repayment under the discriminatory, “redlining” practice that restricted lending. Today, those same areas are exposed to more air pollution than other urban neighborhoods, and according to research published in ACS’ Environmental Science & Technology, the cause could ...

Tuna is one of the most popular seafoods worldwide. But this protein-rich fish can build up high levels of methylmercury from feeding on contaminated prey, like smaller fish or crustaceans. Despite efforts to reduce mercury emissions into the environment, researchers report in ACS’ Environmental Science & Technology Letters that levels in tuna appear to be unchanged since 1971. They warn that more aggressive emission reduction targets are needed to start nudging down tuna mercury levels. Environmental ...

With ever-increasing life expectancy comes the challenge of treating age-related disorders such as osteoporosis. Although there are effective drugs for treating this metabolic bone disease, they can be expensive and have side effects, limiting their availability to some people. In the search for alternative drug candidates, researchers reporting in ACS Central Science have discovered and fully replicated a compound from a botanical source, female ginseng, that had potent anti-osteoporotic activity in cellular tests. Osteoporosis and low bone mass impact 54 million American ...

History determines who gets to breathe fresh air, according to a new study published today in Environmental Science and Technology. The CIRES led-study found that historic, discriminatory lending practices known as redlining in the city are linked to inequities in air quality today. Alex Bradley, a fourth-year chemistry Ph.D. student in CIRES’ de Gouw group at the University of Colorado Boulder, used his background in chemistry coupled with an environmental justice lens to understand how pollution impacts communities of color in Denver.  What he discovered wasn’t ...

As people with autism grow up, they face unique challenges. They find it difficult to deal with mental health issues. There is a big gap in understanding how pretending to fit in (known as social camouflage), cultural beliefs, and mental well-being are connected. This is especially true for non-Western countries like Japan. In societies that stress conformity, autistic individuals may feel more pressure to act non-autistic. This, in turn, affects their mental health. Not enough studies in Japan have investigated this concern, which leaves a crucial gap in our ...

PULLMAN, Wash. -- Students tend to like friendly teachers, but they like those who believe they can improve even more, new research indicates. Students in a study still responded positively to instructors described as being cold but who also had a growth mindset, meaning they felt students’ ability in a subject could improve by working hard and trying different strategies. The opposite was also true: more participants reacted negatively to a warm, smiling teacher when they stated a fixed mindset, which is a belief that innate abilities cannot be changed, such as someone being naturally good at math. “It's not enough to just be nice,” said lead author Makita ...

Toronto, ON — A new longitudinal study from the University of Toronto highlights the substantial mental health toll of the COVID-19 pandemic on older adults with a history of stroke. Researchers examined a sample of over 500 older adults with a history of stroke from the Canadian Longitudinal Study on Aging, a large dataset of older Canadians. Their findings indicated high levels of depression in this population during the COVID-19 pandemic. “People who have experienced a stroke are already highly vulnerable to adverse mental health outcomes, such as depression,” said lead author Andie MacNeil, a research assistant at the University ...

Queensland researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic resistance. Professor Mark Schembri and Dr Nhu Nguyen from The University of Queensland’s Institute for Molecular Bioscience and Associate Professor Sumaira Hasnain from Mater Research found the mutation in the cellulose making machinery of E. coli bacteria. Professor Schembri said the mutation gives the affected E. coli bacteria the green light ...

New research of northern elephant seals has revealed their reproductive and foraging success has been affected by a population bottleneck which nearly caused their extinction and could make them vulnerable as the environment changes in the future. The northern elephant seal is an iconic species living along the very accessible Pacific coastline of Mexico and North America, hauling out on beaches to breed. For much of the 19th century, they were hunted for the oil derived from their blubber. They were thought extinct after the last few that could be found were taken in 1892. Fortunately, around 20 had survived, and they made a remarkable comeback. Now less than 150 years later, ...
