Opinion: Alex Pretti was a nurse to the end On Saturday, amid demonstrations over Immigration and Customs Enforcement activity in Minneapolis, federal agents fatally shot Alex Jeffrey Pretti, a 37-year-old intensive care unit nurse. Videos of Pretti’s last moments show him acting non-violently: filming officers’ actions, directing traffic, and attempting to help a woman who […]
Like many of my friends, I enjoy a glass of wine with dinner or a beer with friends. But a recent U.S. surgeon general report warning that any alcohol consumption is unsafe made me pause. Should I embrace “Dry January,” or even quit altogether? Recently, at least eight respected medical societies and government agencies have issued reports

The FDA has approved a new oral antibiotic to treat gonorrhea, marking the second new drug approval for this sexually transmitted infection in two days. The bacterium Neisseria gonorrhoeae has developed resistance to existing treatments, with ceftriaxone being the last reliable option. Reports of treatment failures are on the rise. Source: STAT
Researchers discovered that 168 common chemicals can disrupt the growth of beneficial gut bacteria, with some also promoting antibiotic resistance. Many of these substances—found in food, water, and household items—weren’t previously suspected of affecting living organisms. A new machine learning model now predicts which chemicals may harm the microbiome. The findings suggest safety testing must

The study reveals that widely used heart-attack risk calculators fail to flag nearly half of those who will soon experience a cardiac event. Even the newer PREVENT model misclassifies many patients as low-risk. Since most people develop symptoms only within 48 hours of their heart attack, current screening offers little time for intervention. Researchers say
Long-term inhalation of toxic air appears to dull the protective power of regular workouts, according to a massive global study spanning more than a decade and over a million adults. While exercise still helps people live longer, its benefits shrink dramatically in regions with heavy fine particle pollution—especially above key PM2.5 thresholds common in many
Scientists have uncovered a stepwise system that guides how the brain sorts and stabilizes lasting memories. By tracking brain activity during virtual reality learning tasks, researchers identified molecules that influence how long memories persist. Each molecule operates on a different timescale, forming a coordinated pattern of memory maintenance. The discoveries reshape how scientists understand memory
Chiral skyrmion flows enable new approach to nanoscale logic devices Researchers have discovered that chiral skyrmions, unique particle-like spin textures in magnetic materials, can be manipulated by electrons. First identified in 2009, these skyrmions can be created and controlled at room temperature, offering potential advancements in nanoscale logic devices. Vir: Phys.org – latest science and
