Scientists have captured a never-before-seen, high-resolution look at influenza’s stealthy invasion of human cells, revealing that the cells aren’t just helpless victims. Using a groundbreaking imaging technique, researchers discovered that our cells actually reach out and “grab” the virus as it searches for the perfect entry point, surfing along the membrane.

Stanford researchers found that gas stoves expose Americans to surprisingly high levels of nitrogen dioxide—often matching or exceeding outdoor pollution. For millions, cooking alone pushes NO2 over long-term safety thresholds. Smaller homes, renters, and rural households face the highest concentrations. Cleaner cooking technologies could substantially reduce the risks.

A unique vaccine rollout in Wales gave researchers an accidental natural experiment that revealed a striking reduction in dementia among seniors who received the shingles vaccine. The protective effect held steady across multiple analyses and was even stronger in women. Evidence also suggests benefits for people who already have dementia, hinting at a therapeutic effect.

A surprising link between constipation and kidney decline led researchers to test lubiprostone, revealing that it can protect kidney function. The results point toward gut-based, mitochondria-boosting therapies as a promising new avenue for CKD care.

Sweat carries a rich mix of biomarkers that advanced wearables can now track in real time. New AI-powered patches analyze biochemical patterns to detect disease risks, medication levels, or stress responses. Researchers are building ultra-sensitive microfluidic devices to read glucose, cortisol, and more—without needles or blood draws. The tech is still emerging, but its potential is huge.
