Drosophila melanogaster shows exquisite light sensitivity for modulation of circadian functions in vivo. yet the activities of the Drosophila circadian photopigment cryptochrome (CRY) have only been observed at high light levels. We studied intensity/duration parameters for light pulse induced circadian phase shifts under dim light conditions in vivo. Flies show far greater light sens... https://www.marketingjeunesse.com/product-category/flip-turn-volumizing-spray/
