‘Multi-kingdom dialogue’ between internal, external microbiota: Implications for Functions Ranging from Tissue Repair to Antimicrobial Responses
National Institutes of Health scientists and their collaborators have identified an internal communication network in mammals that may regulate tissue repair and inflammation, providing new insights on how diseases such as obesity and inflammatory skin disorders develop. The new research is published in Cell. The billions of organisms living on body surfaces such as the […]
VA Restricts Research Publishing; Makary Bashes CDC Committee; Musk’s Drug Use
Note that some links may require registration or subscription. Veterans Affairs physicians and scientists were ordered to not publish in medical journals or speak with the public without first seeking clearance from political appointees of President Donald Trump, the Guardian reported. FDA Commissioner Marty Makary, MD, MPH, called the CDC’s independent advisory body on immunizations […]
Memory helps us evaluate situations on the fly, not just recall the past: Widely known as crucial for long-term memory, hippocampus also supports short-term memory
Scientists have long known the brain’s hippocampus is crucial for long-term memory. Now a new Northwestern Medicine study has found the hippocampus also plays a role in short-term memory and helps guide decision-making. The findings shed light on how the hippocampus contributes to memory and exploration, potentially leading to therapies that restore hippocampal function, which […]
How fasting may protect against inflammation
Cambridge scientists may have discovered a new way in which fasting helps reduce inflammation — a potentially damaging side-effect of the body’s immune system that underlies a number of chronic diseases. In research published in Cell Reports, the team describes how fasting raises levels of a chemical in the blood known as arachidonic acid, which […]
Tackling Climate Change Starts With a Focus on Health, Lancet Report Says
The eighth Lancet Countdown report — a collaboration between scientists and health practitioners from around the world — paints a dire picture of continued inaction around climate change and its human cost. “In this year’s report, new projections reveal the dangers of further delays in action, with every tracked health dimension worsening as the climate […]
Jet lag disorder associated with shift work can lead to brain changes increasing appetite
Scientists have uncovered why night shift work is associated with changes in appetite in a new University of Bristol-led study. The findings, published in Communications Biology, could help the millions of people that work through the night and struggle with weight gain. Scientists from Bristol and the University of Occupational and Environmental Health in Japan, […]
Scientists says identifying some foods as addictive could shift attitudes, stimulate research
Researchers from the United States, Brazil, and Spain, including scientists with the Fralin Biomedical Research Institute at VTC, published an analysis in a special edition of the British Medical Journal with a timely and controversial recommendation: It’s time for an international shift in the way we think about ultra-processed food. “There is converging and consistent […]
Brain’s ‘appetite control center’ different in people who are overweight or living with obesity
Cambridge scientists have shown that the hypothalamus, a key region of the brain involved in controlling appetite, is different in the brains of people who are overweight and people with obesity when compared to people who are a healthy weight. The researchers say their findings add further evidence to the relevance of brain structure to […]
Scientists build a healthy dietary pattern using ultra-processed foods
Scientists at the USDA Agricultural Research Service’s (ARS) Grand Forks Human Nutrition Research Center led a studythat demonstrates it is possible to build a healthy diet with 91 percent of the calories coming from ultra-processed foods (as classified using the NOVA scale) while still following the recommendations from the 2020-2025 Dietary Guidelines for Americans (DGA). […]
A special omega-3 fatty acid lipid will change how we look at the developing and aging brain
Scientists from Singapore have demonstrated the critical role played by a special transporter protein in regulating the brain cells that ensure nerves are protected by coverings called myelin sheaths. The findings, reported by researchers at Duke-NUS Medical School and the National University of Singapore in the Journal of Clinical Investigation, could help to reduce the […]
