Obesity leaves lasting molecular tags on the immune system

People who live with obesity are 'tagging' a memory of being overweight on a key part of the immune system - leaving people with ongoing risk of obesity-related conditions years after losing weight, according to a 10 year-long study published in EMBO Reports.

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.

Global debate continues over fair allocation of donor hearts

As demand for heart transplants continues to far exceed the number of available donor hearts, experts at today's 46th Annual Meeting and Scientific Sessions of the International Society for Heart and Lung Transplantation (ISHLT) explored a critical question: how should this scarce, life-saving resource be allocated?

Natural compound obakulactone shows therapeutic potential for rheumatoid arthritis

A new study published in Engineering reveals that obakulactone (OL), a natural tetracyclic triterpenoid isolated from Phellodendri cortex, exerts a therapeutic effect on rheumatoid arthritis (RA) by promoting the degradation of acyl coenzyme A thioesterase 1 (ACOT1) via the ubiquitin‒proteasome pathway and restoring the homeostasis of unsaturated fatty acids.

Study finds different types of crystalloid fluids are equally effective for pediatric sepsis

A major study, led by researchers at Children's Hospital of Philadelphia, Nemours Children's Health, and Children's National Hospital and involving an extensive network of medical centers across the United States and abroad, found that different types of crystalloid fluid resuscitation were equally effective for staving off the most serious adverse kidney events after the treatment of pediatric patients with suspected septic shock.
