This week in science, scientists have discovered a surprising bonus benefit from the keto diet, which could help muscles respond better to exercise. The high-fat, low-carb keto supplement led to a remodeling of mice's muscles, making them more oxidative and reacting better to aerobic exercise. CERN has discovered a new particle, Xi-cc-plus, which is four times heavier than the proton and is the first new particle identified after upgrades to the LHCb detector. A study of life expectancy in the US has found that people born between 1970 and 1985 have worse mortality rates than earlier generations. A new study found that exercise can rapidly alter the neural rhythms and brain networks involved in memory and cognitive function.
