Why might a higher BMI at 20 be linked to lower breast cancer risk later in life?

A large UK cohort study found that higher BMI at age 20 was associated with lower postmenopausal breast cancer risk, while higher BMI in later adulthood was linked to increased risk. Lower VAS percentage mammographic density appeared to explain part of the early-adulthood association, while fibroglandular volume showed a different relationship with life-course adiposity.

Sprint exercise sends a very different molecular signal through the body

Sprint-interval exercise triggers a much larger and faster shift in circulating proteins and metabolites than moderate-intensity exercise, revealing distinct patterns of predicted communication between organs. The findings suggest that exercise intensity shapes systemic molecular signaling, with skeletal muscle and adipose tissue emerging as potential source and target tissues linked to cardiometabolic health.

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.

Insights into the clinical presentation and management of sellar chondrosarcomas

Chondrosarcomas are a malignant form of bone cancer that is composed of cartilage-forming tumor cells. Sellar chondrosarcomas, which occur in the sellar region at the base of the skull, are a very rare manifestation of chondrosarcoma, making up only around 0.2% of all tumors found in the skull.

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.
