When people debate highly controversial issues, they often misrepresent the other side’s arguments. A recent study tested whether individuals can accurately describe the beliefs of their political or social opponents and found that people are generally very good at understanding opinions with which they disagree. These results are cognitive science. Measuring open-mindedness has historically been a challenge for psychologists. Traditionally, researchers have used self-report surveys that ask people to rate their intellectual habits. Participants may be asked to agree or disagree with statements about whether or not to listen to contradictory evidence. Other surveys ask people to say whether they…

Researchers at the University of Arizona Health Sciences identified the following compounds: cannabis sativa A plant that could offer a new way to treat fibromyalgia and post-surgical pain. The survey results are pharmacological reportthere is growing evidence that certain cannabis-derived molecules may help relieve chronic pain without causing the psychoactive effects associated with THC. This study builds on previous work in the lab of Dr. John Streicher, a member of the Comprehensive Center for Pain and Addiction, which found that terpenes can reduce pain in models of inflammation and chemotherapy-related nerve injury. “Our research shows that terpenes are not a…

Researchers at the University of Technology Sydney have demonstrated a new way to control tiny quantum light sources by twisting atomically thin layers of hexagonal boron nitride. This advance provides scientists with a new way to tune quantum emitters. Quantum emitters are tiny light sources that could play a key role in future technologies such as quantum computing, secure communications, and ultra-sensitive sensors. Lead author Dr Angus Gale said the study provides researchers with a valuable new tool to make these quantum systems more practical. “We can measure these quantum emitters and confirm their existence, but it’s difficult to actually…

A night without sleep leaves certain chemical traces in saliva that can be reliably detected with high accuracy. A recent study published in the Journal of Proteome Research provides evidence that acute sleep deprivation creates a unique pattern of molecules in the mouth, ultimately paving the way for rapid tests that can identify exhausted drivers and workers. This study suggests that as few as 10 to 12 specific biomarkers are sufficient to distinguish between those who are awake 24 hours a day and those who are well rested. A team of scientists from the University of Zurich in Switzerland designed…

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…
