Researchers identify unique circadian rhythm photoreceptor
...ding to Rosbash, applying findings about circadian photosensitivity
in fruit flies to mammals is currently problematic because a mammalian circadian photoreceptor has not yet been identified. Mammalian cryptochrome molecules appear to be involved in the central clockwork mechanism, rather than in light-detection, he ...
Aslera improves lupus disease activity and symptoms

Molecule helps pupils respond to light
...animal could be directly attributed to the loss of photosensitivity
of these retinal ganglion cells rather than to elusive causes such as mis-wiring in the circuitry," said Yau. To determine the physiological effect of the melanopsin-deficient cells, the researchers chose to measure how the pupils of the knockout mic...
