Researchers at the University of Cambridge have uncovered new insights into the emotional lives of dogs, helping to explain why some Golden Retrievers are more anxious, energetic or aggressive than others. Their research is Proceedings of the National Academy of Sciencesdemonstrated for the first time that certain genes associated with dog behavior are also associated with human traits such as anxiety, depression, and intelligence. Genetic clues behind golden retriever personality To investigate the biological roots of dog temperament, scientists examined the DNA of 1,300 golden retrievers and compared it to each dog’s behavioral profile. Owners provided detailed survey responses describing…

New research published in journal personality and individual differences It suggests that an individual’s ability to cope with uncertain situations influences political choices. This study provides evidence that people who struggle with ambiguity tend to prefer stricter ideologies and, as a result, are more likely to support radical right parties. These findings highlight how fundamental psychological responses to an increasingly complex world can shape broader political movements. Past research suggests that a wide range of personality traits influence voting behavior, but the exact pathways are still unclear. To investigate this dynamic, researchers focused on a psychological concept called ambiguity tolerance.…

A newly discovered biological chain reaction explains how high levels of common brain chemicals cause cells to go into overdrive in autism spectrum disorders. By tracking how nitric oxide disables protective proteins and accelerates cell growth pathways, researchers have identified specific targets that may one day lead to new treatments. The results of this study were recently published in the journal molecular psychiatry. Autism spectrum disorders involve differences in brain development that affect social communication and daily behavior. The biology behind these changes involves many genetic and environmental factors. Researchers observed that a signaling pathway called mTOR often operates abnormally…

O. Rose Broderick reports on health policy and technology governing the lives of people with disabilities. Before coming to STAT, she worked at WNYC’s Radiolab and Scientific American. Her article debunking false theories about transgender children was nominated for a 2024 GLAAD Media Award. You can access Rose On Signal at rosebroderick.11.A federal commission that advises scientists, health organizations and Congress on autism issues has canceled its first public meeting since new commissioners were appointed earlier this year, a spokesperson said. No reason was given. “The IACC will not be convening later this month. Further information will be shared as…

Recent research published in personal relationship This provides evidence that people with highly trusting and kind personalities do not actively seek out partners who are manipulative or cruel. Rather, they are just less likely to reject these types of people than the average person. This dynamic suggests that a strong tendency to see the good in others can make people less selective in romantic situations. The authors of the new study sought to better understand how contrasting personality traits interact during the very early stages of romantic attraction. In the study of relationships, there is an idea known as complementarity.…

Bone and skeletal injuries are a major cause of long-term disability worldwide. Researchers at Sweden’s Lund University have developed a cell-free cartilage structure designed to guide the body in repairing damaged bone. Research shows that this artificial graft can promote bone healing without triggering a strong immune response. The method has already been successfully tested in animal models, and researchers are preparing to evaluate the approach in human studies. Large bone injuries often require a graft. When large sections of bone are destroyed or removed, the body may have a hard time repairing the damage on its own. This can…

A study by Dutch researchers found that people with higher levels of ADHD symptoms were more likely to engage in problematic social media use and problematic gaming. However, this association is not mediated by cognitive deficits underlying ADHD, such as inhibitory control deficits, reward sensitivity, or temporal processing deficits. The paper is addictive behavior. Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition characterized by persistent patterns of inattention, hyperactivity, and impulsivity that interfere with daily functioning. It usually begins in childhood but continues into adulthood in many people. In most cases, children are first diagnosed when they begin school and their…

Researchers led by UCL scientists have discovered a protein that appears to cause diabetic retinopathy, a common eye disease caused when high blood sugar damages blood vessels in the retina. This condition is one of the leading causes of vision loss in working-age adults. The study, carried out in mice and supported by Diabetes UK, Moorfields Eye Charity and Wellcome, could change the way doctors approach the disease. Future treatments may be able to stop vision loss before it starts, rather than treating damage after it has already occurred. Protein LRG1 is associated with early retinal damage The survey results…

Scientists at the Mayo Clinic Center for Individualized Medicine have identified a rare genetic variation that may directly cause fatty liver disease associated with metabolic dysfunction, formerly known as nonalcoholic fatty liver disease. Researchers previously thought the condition was primarily caused by a combination of genetic susceptibility and lifestyle and environmental influences. However, the research results published in hepatology We show that in certain cases, single genetic mutations can play a central role in triggering the disease. The researchers identified mutations in the MET gene, which plays an important role in liver repair and how the body processes fat. When…

Recent research published in Psychiatric research: neuroimaging It has been suggested that people with borderline personality disorder show distinct structural differences in certain areas of their brains when they hear their voices. These physical brain differences tend to manifest in areas involved in language processing, sensory integration, and emotional regulation. This finding provides evidence that hallucinations may arise from biological mechanisms that are partially shared across different mental health conditions. Borderline personality disorder (BPD) is a severe mental health condition characterized by profound difficulties with self-image, unstable relationships, and difficulty managing emotions. In addition to these well-known symptoms, up to…
