Most people imagine our early primate ancestors swinging through lush tropical forests. However, recent studies have shown that they can withstand cold temperatures. As an ecologist who has studied chimpanzees and lemurs in the field in Uganda and Madagascar, I am fascinated by the environments that shaped our primate ancestors. These new discoveries overturn decades of assumptions about how and where our lineage began. The question of our own evolution is of fundamental importance in understanding who we are. The same forces that shaped our ancestors have shaped us and will shape our future. Climate has always been a major…

Children and adolescents who exhibit symptoms of attention-deficit/hyperactivity disorder experience a continued decline in overall well-being throughout their development. A new longitudinal analysis shows that these quality of life disparities extend to physical, emotional, and social functioning from ages 4 to 17. The findings were published in the Journal of Attention Disorders. Attention-deficit hyperactivity disorder is a very common childhood neurodevelopmental disorder. This includes persistent patterns of inattention, excessive movement, and impulsive behavior. While much of the evaluation of this condition focuses on school performance and behavioral disturbances, overall health status goes beyond just educational achievement and symptom management. The…

Tumor suppressor genes are often considered the body’s built-in defense system against cancer. It produces proteins that help maintain and repair DNA, reducing the chance of harmful mutations accumulating. When these genes no longer function properly or are present at low levels, cancer risk can increase. But new research suggests that having too much of one DNA repair protein can also be a problem. Researchers at Penn State College of Medicine have discovered that excessive activity of the gene EXO1 can damage rather than protect DNA. Instead of repairing genetic material, when EXO1 is in excess, it destroys DNA and…

Cobalt is a key ingredient in lithium-ion batteries used in electric vehicles and energy storage systems, but new research suggests the global cobalt supply chain may be much more vulnerable than previously realized. Rather than being confined to a single shortage, disruptions in one country or production stage can spread through networks and cause cascading failures across multiple regions and industries. By combining material flow analysis and multilayer shock propagation models, the researchers found that risks often occur in the upstream parts of the supply chain, but are most severe at key refining and manufacturing bottlenecks. This study shows that…

Recent research published in journals deviant behavior This suggests that professional soccer players with a history of concussions are more likely to be arrested than those without such a history. These findings provide preliminary evidence that brain injuries sustained in high-impact sports may be associated with subsequent interactions with the criminal justice system. Traumatic brain injury is a type of injury that affects the normal functioning of the brain. These injuries are often caused by a hard blow or impact to the head, or sudden acceleration or deceleration of the body. This rapid movement causes the brain to bounce and…

A study of men convicted of intimate partner violence against women found that men who reported experiencing physical or psychological abuse in childhood tended to exhibit greater physical aggression toward their partners. Impulsivity may mediate the association between childhood maltreatment experiences and adult intimate partner violence. The paper was published in. Psychiatric Research Journal. Intimate partner violence is harmful or abusive behavior by a current or former romantic partner. It can occur in marriages, dating relationships, cohabiting partnerships, and ended relationships. Intimate partner violence takes many forms. For example, physical violence includes acts such as hitting, pushing, kicking, choking, and…

The popularity of GLP-1 therapeutics such as semaglutide (Ozempic, Wegovy, Rybelsus) and tirzepatide (Mounjaro, Zepbound) has dramatically changed the treatment of obesity. But experts say these drugs are just one piece of the puzzle in managing one of the most prevalent chronic diseases in the United States. A new commentary has been published in the Journal of the American College of Gastroenterology Gastroenterology We revisit the influential POWER (Practical Guide to Obesity and Weight Management, Education, and Resources) framework, first introduced in 2017. Titled “Revisiting POWER in the GLP-1 Era,” this update reflects major developments in obesity care, from the…

Same-sex attraction in Iran appears to be concentrated within families, and is associated with a lower number of biological children in some groups, according to a study published in . human nature. From an evolutionary perspective, same-sex sexual orientation has often been treated as a puzzle because it is directly associated with reduced reproduction, but it continues to emerge across cultures and historical periods. Previous research suggests that genetic factors contribute to same-sex attraction, and familial, twin, and molecular genetic studies indicate that same-sex attraction can persist within families. However, much of this research has focused on European American samples,…

Recent research published in natural neuroscience provide evidence that the biological diversity of autism can be classified into different brain connectivity subtypes. After analyzing brain scans from both mouse models and human participants, scientists found that people on the autism spectrum tend to have abnormally high or abnormally low levels of communication between different brain regions. These two patterns appear to be driven by very different biological mechanisms, suggesting new ways to understand and potentially support people with autism. Autism spectrum disorders are known for their wide variety of characteristics. Some people with autism experience significant difficulties with language and…
