Fruit flies remember a good meal; Blood growth factor activates neural stem cells

Two recent highlights from ’s weekly open-access journal :

Meal Energy Content Affects Fruit Fly Memory
This image shows appetitive long-term memory forms in after presentation of an odorant with sugar. et al. show that, during long-term memory formation, a pair of dopaminergic neurons informs the about the energy content of the ingested food.
