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…
By studying and manipulating heart tissue in the unique low-gravity environment of space, Dr. Arun Sharma’s lab is discovering new ways to protect and repair failing hearts. He was speaking today at the 46th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) in Toronto. Dr. Sharma explained that space is a yin-yang environment that promotes tissue aging and degradation and provides an ideal environment for growing more complex three-dimensional heart tissue and patches from patient-specific stem cells. Heart disease experiments conducted in space with rapid results “In microgravity, the deterioration of cardiovascular conditions…
Researchers at Brown University and their collaborators have developed a new method to measure cell properties. They say this is an important advance because accurately measuring changes in cell elasticity can help better understand diseases, diagnose patient symptoms and provide more accurate prognoses. For example, cancer cells from a tumor typically soften as they become more dangerous and spread more easily, whereas blood diseases such as malaria and sickle cell can harden red blood cells. Mechanical changes at the cellular level are also observed in neurodegenerative, cardiovascular, and chronic inflammatory diseases. As detailed in a study in the journal lab…
New research published in Journal of Sex Research It suggests that the specific words used to describe people in the commercial sex industry shape how the public views them. The findings provide evidence that terms such as ‘sex worker’ and ‘escort’ carry less stigma and are viewed more positively than terms such as ‘prostitute’ and ‘prostitute’. This suggests that changing the language used in the media and legal settings may help reduce bias against these professionals. Researchers conducted this study to better understand the powerful role language plays in shaping social prejudice. “Truth is, this study is very personal to…
