  • 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 […]
  • Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate stress-response pathways. Simulations show the damage makes mtDNA more rigid, possibly marking it for removal. The finding offers fresh clues to inflammation, aging, and diseases such as […]
  • Warming up significantly improves muscle performance, particularly speed and power, by increasing muscle temperature. Both passive heat methods and light exercise warm-ups work, but mimicking the actual workout movements can offer extra benefits. When your body starts to feel coordinated and lightly sweaty, you’re ready to push into the main session.
  • Chronic cannabis use is increasingly linked to recurring bouts of vomiting, now officially classified as cannabis hyperemesis syndrome. The new ICD code helps doctors identify cases more consistently and gives researchers a clearer picture of how often it occurs. Patients often resist the diagnosis, and the condition’s causes remain murky. Relief can come from unusual […]
  • University of Queensland researchers visualized yellow fever virus particles at near-atomic detail, uncovering major structural differences between vaccine and virulent strains. The insights could lead to better vaccines and treatments for yellow fever and related mosquito-borne viruses.
  • 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 […]
