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 ...

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 . ...

Using intense X-rays, researchers captured a buckyball as it expanded, split and shed electrons under strong laser fields. Detailed scattering measurements showed how the molecule behaves at low, medium and high laser intensities. Some predicted ...

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. ...

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 ...

Human development and climate-driven sea level rise are accelerating global beach erosion and undermining the natural processes that sustain coastal ecosystems. Studies reveal that urban activity on the sand harms biodiversity in every connected zone ...

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 ...

Researchers have discovered a low-energy way to recycle Teflon by using mechanical motion and sodium metal. The process turns the notoriously durable plastic into sodium fluoride that can be reused directly in chemical manufacturing. This creates a . ...

A photosynthetic bacterium shows a surprising ability to absorb persistent PFAS chemicals, offering a glimpse into biological tools that might one day tackle toxic contamination. Researchers are now exploring genetic and synthetic biology approaches ...

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 ...
