Researchers from Tokyo Metropolitan University have used fruit flies to study how daily eating patterns are regulated. They found that the quasimodo (qsm) gene helped sync feeding to light/dark cycles, but not in constant darkness: instead, the genes clock (clk) and cycle (cyc) keep eating/fasting cycles, while other “clocks” in nerve cells help sync it to days. Deciphering the molecular mechanism behind eating cycles helps us understand animal behavior, including our own.
