Early puberty and childbirth tied to accelerated aging and higher disease risk

Reproductive timing matters when it comes to aging and age-related disease. In a study now online at eLife¸ Buck researchers determine that girls who go through puberty (the onset of menstruation) before the age of 11 or women who give birth before the age of 21 have double the risk of developing type 2 diabetes, heart failure and obesity and quadruple the risk of developing severe metabolic disorders.

Irregular sleep patterns linked to higher mortality risk

Researchers in Korea followed over 9,600 adults for 15 years and found that both short and long sleep durations, especially when irregular, were linked to higher risk of death. The study highlights that 7–8 hours of regular sleep may be optimal for longevity.

Trial finds no cardiovascular benefit and higher safety risks with spironolactone in dialysis patients

A large international study has found that spironolactone, a medication for high blood pressure and heart failure, does not reduce the risk of heart-related death or hospitalizations in people with kidney failure receiving dialysis, despite earlier smaller studies suggesting benefit.

Study finds vegetarians less likely to develop several common and rare cancers

A large North American cohort study found that vegetarian diets were linked to lower risks of several cancers, including colorectal, stomach, breast, prostate, and lymphoproliferative cancers. No evidence suggested that vegetarian eating increased cancer risk for any site.

Pandemic left measurable changes in teen brains, hormones, and immunity

Adolescents assessed after COVID-19 lockdowns showed lower daily cortisol, higher inflammation, and reduced prefrontal cortex activity compared to matched pre-pandemic peers, suggesting widespread stress-related biological changes. These alterations mirror patterns seen after prolonged early-life stress, raising concerns about long-term health risks.

Brain’s energy control map offers blueprint for next-gen weight loss therapies

Scientists map how the brain integrates hormonal and neural signals from the body to control appetite, energy use, and reward pathways, revealing targets for next-generation anti-obesity drugs. This review highlights the interplay between neuroendocrine circuits, neuroplasticity, and pharmacotherapy for durable, non-aversive weight loss.

Researchers uncover dozens of traits driven by maternal versus paternal genes

Researchers developed a high-accuracy method to infer whether genetic variants come from the mother or father without needing parental genomes, analysing 286,666 UK Biobank participants. They uncovered over 30 parent-of-origin effects on traits from growth and metabolism to diabetes, many showing opposite effects depending on parental source.
