Intermittent fasting edges daily calorie cuts for blood pressure and long-term cardiovascular risk estimates
In a real-world registry study of adults with overweight or obesity, 5:2 intermittent fasting and daily calorie restriction both improved blood pressure over 12 weeks. Intermittent fasting produced modestly greater reductions in systolic and pulse pressure and a larger drop in BMI-based 30-year cardiovascular risk scores, without superior lipid or glycaemic effects.

Plant-based omega-3s work better than expected in a year-long diet study
A year-long, diet-controlled intervention shows that flaxseed oil–derived alpha-linolenic acid significantly increases erythrocyte EPA, DPA, and DHA across omnivorous, vegetarian, and vegan diets. The magnitude of improvement is driven mainly by baseline omega-3 status, while absolute EPA and DHA levels in vegans remain lower than in omnivores.

Brain structural changes linked to chronic PTSD in World Trade Center responders
New research among World Trade Center (WTC) responders with chronic post-traumatic stress disorder (PTSD) has uncovered measurable physical changes in their brain structure, consistent with changes in the balance of myelinated to unmyelinated neurons (fast- and slow-conducting nerve cells) across both hemispheres of the brain.

SARS-CoV-2 manipulates host cell's RNA to weaken the immune response
Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense system.

Early embryos and the uterus engage in active communication during implantation
A new study shows that the embryo and the uterine lining conduct an active "conversation" from the very earliest stages of implantation. They engage in a back and forth of tiny packages called extracellular vesicles and lipid droplets, which carry metabolites and signals.
