Artificial gravity protects the immune system of mice in space


Mice who experienced artificial gravity on the ISS suffered less damage to their immune system (thymus) than weightless mice did.

Mathematical model predicts self-organized learning in real neurons


The free energy principle predicted how real neural connections changed as neurons “learned” in a dish.

Low-protein diet changes sperm and health of future offspring


Low-protein diets in male mice alter sperm and result in offspring that have metabolic problems like diabetes in adulthood.

Most precise measurement ever of proton magnetic moment


Using a sophisticated setup, scientists have made the most precise measurement to date of the proton magnetic moment.

Why (mouse) mothers take risks to protect their infants


The calcitonin receptor and its ligand amylin act in the brain to motivate mouse mothers to protect their pups, even in risky/dangerous situations.

Promising mouse model for Ngly1 deficiency
