A breakthrough in magnetism could make AI chips use dramatically less energy

Researchers have uncovered a surprising hidden function of a protein that may hold the key to repairing damaged muscles and treating muscular dystrophy. Known for protecting chromosomes, TRF2 also helps muscle stem cells maintain their identity and regenerate injured tissue. When scientists removed the protein in mice, muscles struggled to repair themselves, and muscular dystrophy progressed dramatically faster.

A surprising new study suggests that where men get their protein may be linked to their testosterone levels. Researchers studying more than 2,500 men found that higher animal protein intake, particularly from dairy, was associated with lower testosterone, while plant protein was linked to higher levels. The findings raise intriguing questions about how everyday food choices might relate to male hormone levels.

Stanford researchers have discovered that children who struggle persistently with math may have underlying differences in how their brains manage problem-solving strategies. Children with developmental dyscalculia were slower to switch strategies, less responsive to changes in difficulty, and less able to improve their approach over time. Distinct patterns of brain activity were linked to these difficulties and could even predict certain math-related abilities.
