Hygiene management is important for everyday items that come into direct contact with the body, such as clothes, masks, and toothbrushes. Scientists have discovered how graphene can selectively eliminate bacteria without harming human cells. This discovery points to a new class of antimicrobial materials that are safe for humans and can reduce reliance on traditional antibiotics. KAIST recently announced that a joint research team led by Professor Sang Ouk Kim from the Department of Materials Science and Engineering and Professor Hyun Jung Chung from the Department of Biological Sciences has identified the mechanism behind the antibacterial properties of graphene oxide…

A new study from the Medical University of South Carolina raises new concerns about fish oil supplements, especially for people who have experienced repeated mild traumatic brain injuries. Writing in the journal Cell Reports, researchers report that these widely used supplements, often touted as protecting the brain, may actually impede healing after injury. The study was led by neuroscientist Onder Albayram, Ph.D., an associate professor at MUSC and a member of the National Trauma Association Committee. His team focused on the biological processes involved in repairing blood vessels in the brain after injury. The growing popularity of omega-3 supplements Interest…

For millions of years, a mixture of bright colors persisted within a single lizard species. Today, much of that diversity has disappeared in an incredibly short period of time. Researchers point to an unexpected cause. It is a bold green, highly aggressive and dominant wall lizard that rapidly eliminated several colored forms within its species. In many animal species, distinct color types known as color morphs are more than just visual differences. These changes often reflect different approaches to survival, such as how individuals compete for territory or attract mates. Each color can represent a unique strategy that helps maintain…

Rising water temperatures in southcentral Alaska’s rivers are causing noticeable changes in the behavior of the invasive northern pike. As water temperatures rise, these predators are feeding more, raising concerns about the future of native fish such as salmon. Researchers led by the University of Alaska Fairbanks examined the stomach contents of northern pike collected by the U.S. Fish and Wildlife Service from the Deshka River in the summers of 2021 and 2022. They compared their findings with samples taken from pike in the same river about 10 years ago. Their analysis showed that as temperatures rose, pike of all…

Adults’ high cognitive abilities usually predict intuition accurately, but this mental shortcut takes time to develop. A new study of middle school and high school students reveals that young people rely heavily on slow, deliberate thinking to solve logical puzzles, before correct intuition has fully matured. The study was recently published in the journal Thinking & Reasoning. Psychologists often divide human thinking into two different categories based on speed and effort. The first type of thinking is fast, automatic, and requires little mental energy. The second type is time consuming, careful, and requires continued attention to detail. For decades, researchers…

Recent research published in journals Frontiers of nutrition Our findings suggest that the health benefits of the Mediterranean diet may come from small proteins produced within the energy-producing structures of cells. Researchers found that older adults who adhered to such a diet had higher levels of two microscopic proteins that protect against heart disease and cognitive decline. These results provide a new biological explanation for how a diet rich in olive oil, fish, and legumes promotes healthy aging at the cellular level. To understand the mechanisms behind these physiological benefits, it helps to look inside human cells. Most people are…

Scientists are increasingly recognizing that the gut microbiome plays an important role in overall health, including the brain. However, researchers are still working to determine exactly which specific bacteria are involved in the disease and how they affect the body. In particular, some bacteria morganella morganiseveral studies have linked it to major depressive disorder. However, until recently, it was unclear whether this microbe contributes to depression, whether depression alters the microbiome, or whether another factor explains the association. Researchers at Harvard Medical School have identified a biological mechanism that strengthens this claim. M. Morgany It can affect your brain health.…

The expanded use of robotic technology in lung transplantation came under scrutiny today at the International Society for Heart and Lung Transplantation (ISHLT)’s 46th Annual Meeting and Scientific Sessions, where experts debated whether its clinical benefits justify the cost and complexity. In the debate, Dr. Stephanie Chan, a thoracic transplant surgeon at New York University Langone Health, argued in favor of robotics, and Hermann Reichenspruner, M.D., a retired surgeon and pioneer in minimally invasive cardiothoracic surgery, argued against it. Robot-assisted thoracic surgery could expand patient population Dr. Chang highlighted the potential of robot-assisted surgery to improve recovery and expand access…

Advances in pediatric heart treatment are allowing more children to survive long enough to receive a transplant, but a critical shortage of donor hearts means too many are dying while waiting, experts warned today at the International Society for Heart and Lung Transplantation (ISHLT)’s 46th Annual Meeting and Academic Session. Presentations by surgeons from the United States and Europe highlighted growing contradictions. Even though medical advances are saving more children, the supply of donor hearts is not keeping pace. Costly delays in implementing the American Transplant Modernization Act Dr. Kevin P. Daly, a pediatric cardiologist at Boston Children’s Hospital, said…

As the demand for heart transplants continues to far outstrip the number of donor hearts available, experts at the International Society for Heart and Lung Transplantation (ISHLT)’s 46th Annual Meeting and Scientific Sessions today considered the important question of how to allocate this scarce lifesaving resource. In a presentation titled “Allocation Models Beyond the United States: Scoring or Status? A Global Perspective,” Guillaume Coutin, MD, highlighted how different countries are approaching this complex challenge and why no single system has emerged as the optimal solution. Approximately 7,000 heart transplants are performed worldwide each year, but approximately 10 to 15 percent…
