Primate study reveals molecular basis of red-green color vision

Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green, or blue light.

Amyloid beta misfolding predicts Alzheimer's years before symptoms appear

Widely used Alzheimer’s biomarker P-tau 217 reliably detects the disease only at the clinical stage. The protein misfolding of amyloid beta indicates an increased risk years earlier.

Different cyclone definitions reveal uneven diarrheal disease risks across Asia

Tropical cyclone links to diarrheal disease varied widely across ten Asian regions, depending on how cyclone exposure was defined and whether mortality or morbidity was measured. Mortality associations were mostly uncertain, while morbidity patterns differed by region, with Taiwan showing the largest attributable burden.

YouTube’s health content rewards attention-grabbing videos over reliable medical information

Researchers analyzed 3,958 Korean-language medical YouTube videos and found that clickbait-heavy content attracted more views, likes, and comments. Higher-quality videos from medical professionals and public institutions often received less attention, highlighting a visibility gap in online health information.

Wild bird surveillance reveals how H5Nx flu keeps returning to China

Long-term wild bird surveillance across China revealed shifting H5Nx avian influenza patterns, with H5N1, H5N8, and clade 2.3.4.4b viruses changing over time and across migratory flyways. Genomic analyses suggest recent H5Nx detections in China largely reflect repeated reintroductions through migratory birds rather than sustained local circulation.

Longer lives now come with more years spent in poor health worldwide

Global life expectancy rose from 64.6 to 73.8 years between 1990 and 2023, but healthy life expectancy did not keep pace. The widening morbidity gap means most populations now spend a decade or more in poor health.

Engineered probiotic bacteria boost immune attack against pancreatic cancer

Cancer immunotherapies have transformed treatment for many cancers, but pancreatic cancer remains especially difficult to treat. One major reason is that pancreatic tumors often create a "cold" tumor microenvironment, where the tumor prevents immune cells from mounting a strong attack.
