In solar cells and digital cameras, ...
... leaves normal vision intact. "It is entirely possible that in many older people a loss of this light sensor is not associated with a loss of vision, but instead may lead to difficulty falling asleep ...
... integrated nanowire photosensor circuitry, the Javey group used cadmium selenide nanowires as visible-light sensors. For the electronics, nanowires with a germanium core and a silicon shell were the ...
... and aids seedling morphogenesis, but too much UV-B light can be toxic.
The study found that plants with a mutated UV-B light sensor gene become hypersensitive to UV-B light and even ...
... report appears online this week in Nature. These light sensors are a small number of nerve cells ... electrical signal. Then there would have to be bright light—giving lots of captured photons—for a signal ...
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain. The report appears online this week in Nature.

... Levskaya initially looked to plants for proteins that might serve as the light sensor. Plants are known to rely upon phytochromes, or light-sensing signaling proteins, to control a variety of ...
... sensory biology, including vision, explains Montell. But rather than being directly triggered by light, a different light sensor molecule activates the TRP vision protein indirectly. Since TRPA1 is ...
... exposing paralyzed C. elegans to ultraviolet light restored normal levels of movement in the worms.
... doesn't resemble any other light sensors previously discovered," said Miller.
Although humans ...
... interplay of plant growth hormones, plant light sensors and circadian rhythms that permit plants ... before dawn is a mystery. But a similar interplay of light sensing, plant hormones and circadian rhythms ...
Instead of using a flat microchip as the light sensor for their new camera, a team of engineers has developed a sensor that is a flexible mesh of wire-connected pixels. The mesh is made from many of ...

It is likely that the close coupling of light sensor to cilia marks an important, early landmark in the evolution of animal eyes. Many ...
Research into creating tiny structures on light sensors could mean digital cameras take better pictures.
... ía (IFEVA) has discovered how plants weigh the tradeoffs and redirect their energies accordingly. The same light sensor that detects other plants crowding in and gives the signal to switch on the ...
