Researchers studying brain-imaging data from people aged between 8 and 100 found that sex differences in the brain's connections are minimal in early life, but then increase drastically at puberty; some of these differences continue to grow throughout adult life. The study was published as a preprint on bioRxiv, and has not yet been peer reviewed. The work could help us to understand why men and women have different likelihoods of developing some mental-health disorders - and perhaps give insight into treating them, say the researchers.
When Lola was eight years old, she went through a massive growth spurt and started developing acne. Her mother, Elise, thought Lola was just growing fast because of genes inherited from her father.

A plant-based diet rich in soy reduces moderate-to-severe hot flashes by 84%, from nearly five per day to fewer than one per day. During the 12-week study, nearly 60% of women became totally free of moderate-to-severe hot flashes. Overall they (including mild ones) decreased by 79%.
