How Fruitflies Know It's Time for Lunch
To control what you eat and when, your nervous system must coordinate a laundry list of signals: internal signals contain information about energy level, food preferences, and metabolic need, while external signals relay information about the quality of available food, determined by its smell and taste. Scientists studying the fruitfly Drosophila have traced the path of olfactory signals b...Researchers identify genes in fruitflies that may shed light on human cancer spread
By searching through all the genes in the fruitfly genome, Johns Hopkins scientists have identified those required for a certain type of cell migration and simultaneously captured a global view of all the genes turned on when cells are on the move. The study, to be published April 3 in Developmental Cell, has implications for understanding cell migration and perhaps controlling cancer cel...
