Eating a high fat diet without getting obese?


Scientists discover that without innate immune cells in the intestines, eating a high fat diet does not lead to obesity in mice.

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.

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.

Leaky plants bad for drought resistance


The KAI2 receptor for compounds found in smoke helps plants retain water and survive during drought.

Social contact-seeking behavior and loneliness in the brain


Levels of the peptide amylin in the brain are related to loneliness; activating amylin neurons in the MPOA drives isolated mice to seek social contact.

Something smells fishy: categorizing odors in the brain


Calcium imaging and mathematical model explain how categories and mixtures of odors are represented in the fly brain and consistent across individual flies.
