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 parts of the world. The researchers emphasize that outdoor activity shouldn’t stop, but better air quality could unlock far greater health gains.

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 diabetes and neurodegeneration.

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 oscillations never appeared, pointing to missing physics in current models. The findings create a clearer picture of how molecules fall apart under extreme light.

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 sources like hot showers or capsaicin cream.
