Whether navigating a job interview, meeting someone for the first time, or dealing with an unexpected challenge, success often depends on your ability to adjust your behavior. In some situations, adapting quickly can even be critical to survival. But how does the brain know when to abandon old strategies and try something new? New research published in nature communications Let’s shed some light on that question. Neuroscientists at Okinawa Institute of Science and Technology University (OIST) have identified a key brain mechanism that helps animals adapt when conditions suddenly change. The findings could advance our understanding of conditions that make…

By analyzing the genetic material of thousands of ancient humans, researchers have mapped how natural selection has influenced hundreds of physical and behavioral traits across Western Eurasia over the past 10,000 years. The findings reveal that evolution continually makes certain genetic variations more or less common, influencing everything from blood type to disease risk. The study was published in the journal Nature. Evolution is driven by multiple forces, but one of the most prominent is directional selection. This occurs when a particular genetic mutation has a survival or reproductive advantage, so that the mutation becomes increasingly common in a population.…

For Novo Nordisk, the company’s long-awaited launch of Wigovy tablets earlier this year, the first oral GLP-1 for obesity, was an opportunity for Novo Nordisk to regain some of the chronic weight management market it had ceded to U.S. rival Eli Lilly. Now, updating the rollout of oral semaglutide products to date, the range of popularity of the pill and its potential to reach new obese patients cannot be ruled out. Since its Jan. 5 pill launch, which preceded Lilly’s launch of oral GLP-1 for Foundayo in early April, oral Wegoby has attracted more than 3 million prescriptions, making it…

Extreme heat and cold increase cardiovascular risk, which can lead to heart attack, stroke, heart failure and sudden cardiac death, according to a recent scientific statement from experts at Weill Cornell Medicine and other leading institutions. A statement from the American Heart Association: circulationHere we outline the factors that put your health at risk and recommendations to reduce the increased cardiovascular risks brought on by extreme temperatures. Historically, deaths from cardiovascular disease have increased in colder climates due to more cold days. However, the report warns that the frequency, intensity and duration of heat waves are increasing, which could lead…

Florida’s year-round sunshine and exposure to intense ultraviolet (UV) rays have resulted in one of the highest burdens of skin cancer in the nation, with older adults bearing the brunt of the burden. A new study from Florida Atlantic University’s Charles E. Schmidt School of Medicine reveals that melanoma, the deadliest of skin cancers, continues to disproportionately affect older Floridians, with persistent disparities in both diagnosis and mortality rates among genders, races, and ethnicities. The findings provide one of the most comprehensive recent assessments of skin cancer trends among Floridians age 65 and older, as the Sunshine State has the…

DTU researchers have contributed to the international scientific research behind WHO’s new global estimates of foodborne illnesses, providing countries with a stronger evidence base to prevent disease and prioritize action. “From Burden to Solution – Safe Food Everywhere.” This is the message for World Food Safety Day 2026. On this day, the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) focus on how new knowledge about diseases, lives lost and social impacts can be translated into practical solutions. WHO today released updated estimates of the global burden of foodborne illnesses and associated productivity…

For more than 30 years, an incredible collection of helmets recovered from the sea off the coast of Spain was believed to date back to Roman times. A new study overturns that assumption, revealing that these artifacts are actually medieval and provide valuable insight into the movement of arms, trade, and military activity across the Mediterranean in the late Middle Ages. The study, led by researchers from the University of Alicante (UA), reexamined 43 helmets discovered in 1990 at the underwater ruins of Piedras de la Barbada, near Benicarlo on Spain’s east coast. The findings were published in the journal…

A new study reveals how antidepressants have opposite effects on different groups of serotonin-producing brain cells, providing new insight into why selective serotonin reuptake inhibitors (SSRIs) can cause unpleasant side effects at the start of treatment, but lead to symptom relief over time. Antidepressants are among the most widely prescribed drugs in the world. More than one in 10 people in Sweden currently uses antidepressants, with SSRIs being the most common type. However, surprisingly little is known about what these drugs actually do in the brain. Our study aimed to map the changes in gene expression that SSRIs cause…

The FDA has expanded the labeling of Pfizer’s subcutaneous hemophilia treatment Himpazi to include patients 6 years of age and older with hemophilia A or B. Anti-tissue factor pathway inhibitors were first approved in October 2024 for patients 12 years and older with hemophilia A or B who have not developed antibodies (also called inhibitors) produced by the immune system that block or destroy injected clotting factor drugs. The new expansion includes all patients 6 years of age and older, regardless of inhibitor status. With this new approval, treatment is now available to people aged 12 and older who develop…
