Study confirms positive effects of exercise on insulin signaling proteins from the brain A study led by scientists at Rutgers University-New Brunswick has shown that specialized cells involved in how the body responds to insulin are activated in the brain after exercise, suggesting that physical activity may directly improve brain function. A study, published in Aging Cell, a journal focused on the biology of aging, indicates that therapies targeting this insulin action may be developed to offset or even prevent dementia progression. “We…
Advanced scientific instruments allow scientists to build a map of brain receptors, opening the door to possible novel ways to treat epilepsy and mental disorders Certain proteins found in the human brain have long been known to be critical to controlling how brain cells communicate with each other. So-called GABAA receptors are proteins that control the flow of ions into and out of cells. As they play such a vital role in how neurons slow down or stop firing, they have…
MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request. EAST LANSING, Mich. – Researchers from Michigan State University’s Department of Human Development and Family Studies revealed that sleep patterns may vary across different racial and ethnic groups — notably for non-white and multiracial children. Yijie Wang is an associate professor of human development and family studies in the College of Social Science, and her research team published a study in JAMA Network Open that explores these variations and the…
Long-term study on wild monkeys in Thailand reveals health risks and opportunities for intervention Maternal stress hormone levels during early pregnancy can have a lasting effect on the stress system of the offspring. The results of a long-term study on wild Assamese macaques in Thailand indicate that maternal stress in the first half of pregnancy is particularly relevant. Elevated stress hormones later during pregnancy or after birth did not have the same effects. The long-term study conducted by the University…
Too Much of a Good Thing… Excessive sugar consumption is linked to several non-communicable diseases, including obesity, cardiovascular disease, metabolic syndrome, and type 2 diabetes. Animals naturally crave sugar, and uncontrolled sugar preferences can lead to high sugar intake, raising the risk of hyperglycemia and metabolic diseases. Gut-Brain Axis and the Regulation of Sugar Cravings Previous research suggests that food cravings in humans are driven by signals from the gut to the brain, highlighting the gut’s crucial role in shaping…
Are humans or machines better at recognizing speech? A new study shows that in noisy conditions, current automatic speech recognition (ASR) systems achieve remarkable accuracy and sometimes even surpass human performance. However, the systems need to be trained on an incredible amount of data, while humans acquire comparable skills in less time. Automatic speech recognition (ASR) has made incredible advances in the past few years, especially for widely spoken languages such as English. Prior to 2020, it was typically assumed…
Low back pain is a leading cause of disability worldwide with many treatments, such as medication, often failing to provide lasting relief. Researchers from the University of Sydney’s Centre for Rural Health have uncovered a possible solution. Their study, published in JAMA Network Open, found integrating lifestyle support into back pain care could reduce disability and enhance quality of life. Study Evaluates Lifestyle-Based Outcomes The randomised controlled trial included 346 participants from across Australia, all of whom had chronic low back pain and…
Groundwater and multilevel cooperation in recovery efforts mitigated water crisis after flooding. Converting Disasters into Opportunities Society is often vulnerable to disasters, but how humans manage during and after can turn devastation into opportunities for improved resilience. An Alternative Water Source: Private Wells For instance, private wells are attracting attention as an alternative resource for securing water for daily use and consumption in the event the water supply is cut off after a disaster. However, there are few records on…
The closest relatives of humans adapt genetically to habitats and infections Survival of the Fittest: Genetic Adaptations Uncovered in Chimpanzees Görlitz, 10.01.2025. Chimpanzees have genetic adaptations that help them survive in different forest and savannah habitats. This is the result of a study published today in the renowned journal “Science”. An international research team led by University College London (UCL) shows that some of these adaptations could also protect the animals from malaria. The researchers emphasize that their results provide…
The Fiber Gap: A Growing Concern in American Diets Fiber is well known to be an important part of a healthy diet, yet less than 10% of Americans eat the minimum recommended amount. A new study from Stanford Medicine might finally convince us to fill our plates with beans, nuts, cruciferous veggies, avocados and other fiber-rich foods. The research, which will be published in Nature Metabolism on Jan. 9 identified the direct epigenetic effects of two common byproducts of fiber digestion and found that…
Scientists show how a mutated gene harms red and white blood cells. LA JOLLA, CA—Scientists at La Jolla Institute for Immunology (LJI) have discovered how a mutated gene kicks off a dangerous chain of events during blood cell production. The study, published recently in the Proceedings of the National Academy of Sciences, reveals how a mutated gene called ASXL1 is involved in a disease called clonal hematopoiesis, a precursor to malignant diseases such as myeloid malignancies and chronic monomyelocytic leukemia. “We know that…
Can strength and endurance training be beneficial for patients with a certain form of heart failure? A research team from Greifswald investigated this question together with seven other research centers in Germany. In the largest study of its kind to date, the effect of one year of training on the health of patients was examined. The research team was able to prove that those affected benefited from better performance and resilience in everyday life. The results have now been published…
Children and young people with high levels of mental health needs are struggling to receive the help they need, or to have their difficulties recognised, according to a new study. STADIA Decodes Young People’s Emotional Struggles The STADIA trial, which is published in the Journal of Child Psychology and Psychiatry, was led by experts from the School of Medicine at the University of Nottingham, and was funded by the National Institute for Health and Care Research (NIHR). The large study, which spans different parts…
Results of a comprehensive analysis refute assumptions that a key immune checkpoint receptor functions the same in rodents and humans The Discovery of PD-1: A Milestone in Cancer Treatment Since its discovery in the 1990s, “programmed cell death protein 1,” or PD-1, has been regarded as a leading target in cancer treatments. A “checkpoint” receptor that often resides on the surface of immune system cells, the PD-1 molecule works as a type of off switch that keeps immune cells from…
To stay healthy, plants balance the energy they put into growing with the amount they use to defend against harmful bacteria. The mechanisms behind this equilibrium have largely remained mysterious. Soil Bacteria: The Unexpected Key to Plant Immunity Now, engineers at Princeton have found an answer in an unexpected place: the harmless, or sometimes beneficial, bacteria that cluster around plants’ roots. In an article published Dec. 24 in the journal Cell Reports, researchers showed that some types of soil bacteria can influence a…
Achilles tendon injuries are common but challenging to monitor during recovery due to the limitations of current imaging techniques. Researchers, led by Associate Professor Zeng Nan from the International Graduate School at Shenzhen, Tsinghua University, have applied Mueller matrix polarimetry, a non-invasive imaging method, to more accurately observe and evaluate the healing of Achilles tendon injuries. This technique offers unique insights by capturing the subtle changes in tendon tissue without needing labels or dyes, allowing for more natural tissue characterization….
