Scientists map 239 human-infective RNA viruses to track future outbreak risks
Researchers updated the global catalogue of human-infective RNA viruses to 239 ICTV-recognised species, incorporating taxonomy, discovery dates, locations, genome links, host range, transmissibility, and transmission routes. The dataset shows that most known human-infective RNA viruses remain strictly zoonotic, while only a minority are endemic in humans or capable of epidemic spread.

Vitamin E intake linked to a key fertility hormone in women trying to conceive
A cross-sectional study of 97 women with infertility found that higher vitamin E intake was associated with lower prolactin levels and smaller hip circumference. Riboflavin and calcium intake were linked to higher muscle mass percentage, but the findings are association-based and need confirmation in longitudinal studies.

Blue Zones longevity claims may rest on flawed records, essay argues
Essay challenges the scientific validity of the Blue Zones concept and Ancel Keys’ Lipid Hypothesis, arguing that both rest on biased data, weak records, and methodological flaws. The authors say some longevity claims may reflect clerical errors, poverty, and unreliable vital records rather than uniquely healthy lifestyles.

Scientists will probe whether processing itself makes ultra-processed foods harmful
A randomized controlled trial protocol will test whether the cardiometabolic risks linked to ultra-processed foods stem from industrial processing, poor nutrient composition, or both. Using four controlled diets, researchers will separate the effects of UPF content from saturated fat, added sugar, and sodium on LDL cholesterol, insulin resistance, and blood pressure.

New cytometer measures cell stiffness to improve disease diagnosis
Researchers from Brown University and their collaborators have developed a new way to measure the properties of cells - an important development, they say, because accurate measurements of changes in cell elasticity can be used to better understand diseases, diagnose patient symptoms and provide more accurate prognoses.
