Type 1 diabetes runners can safely complete marathons with careful glucose management

New research to be presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28th – Oct 2nd) shows, with the use of continuous glucose monitoring (CGM) devices people with type 1 diabetes can complete a marathon safely and achieve finishing times similar to runners without diabetes.

Exercise usually helps the brain. During a 15-day fast, the story was different

In a 28-day controlled study of 22 healthy adults, 15 days of complete fasting produced a glucose-to-ketone metabolic shift and selectively affected attention and implicit learning while time perception remained relatively stable. Moderate-intensity exercise during early fasting was associated with poorer performance on some learning measures, while fasting also increased sleepiness and reduced calmness at some time points.

Prenatal paracetamol exposure linked to smaller ovaries in daughters

Researchers in Denmark have found that girls whose mothers took paracetamol during pregnancy had smaller ovaries, fewer ovarian follicles (the structures that contain immature eggs), smaller uteruses and lower levels of reproductive hormones at three months old.

What 107 professional MMA fighters actually ate before and after weigh-in

Professional UFC fighters followed highly structured dietary patterns around competition, sharply restricting carbohydrates, fiber, fluids, and sodium before weigh-in before rapidly increasing carbohydrate, fluid, and sodium intake afterward. Despite aggressive post-weigh-in refueling, carbohydrate intake fell again on fight day, suggesting that some fighters may not fully restore glycogen stores before competition.

Why keto appears to lower blood pressure for some people but not others

A narrative review finds that ketogenic diets may modestly lower blood pressure through weight loss, reduced visceral fat, improved insulin sensitivity, fluid and electrolyte shifts, and anti-inflammatory effects. However, effects vary across studies, long-term cardiovascular evidence remains limited, and diet quality, hydration, electrolyte balance, and medication monitoring are important.

Study sheds new light on the physiological roles of protein quality control at the ribosome

Scientists at the Center for Molecular Medicine Cologne (CMMC) and the CECAD Cluster of Excellence on Aging Research have demonstrated in a biomedical study that ribosomes, the protein factories of our cells, face an unusually tough challenge when building large, membrane‑embedded proteins.

Study links higher body fat to lower sperm counts despite normal BMI

Among 1,058 Danish men, higher body fat percentage was associated with lower total sperm count and altered reproductive hormone levels, but not testicular volume. Body fat percentage showed stronger links with several semen measures than BMI or waist-to-height ratio, with the sperm-count association strengthening among men with normal BMI.
