It involves using proteins that are sensitive to light, derived from other organisms such as algae, and putting them into neurons.
Rods are very sensitive to light, shapes and movements and cones are not as sensitive, but they control the perception of color.
FORBES: First Bionic Eye For US Market Awaits Approval From FDA
Dr Hoch's team extended this idea, arguing that as a plant starts to disassemble its light-gathering apparatus in preparation for winter, its leaves become particularly sensitive to light damage.
The truth is, most bad headaches -- the ones that make getting through the day a chore or make you feel nauseated or sensitive to light -- are the Big M.
In a procedure known as photodynamic treatment, which has been studied for years, certain pharmaceutical ingredients that are sensitive to light can kill acne when turned on by specific light wavelengths.

The near-infrared photoactive polymer absorbs more near-infrared light but is less sensitive to visible light, balancing solar cell performance and transparency in the visible wavelength region.
ENGADGET: UCLA creates transparent solar cell, dreams of current generating windows
The material is an organic photovoltaic semiconductor (called rr-P3HT) which, unlike the metal or silicon-based materials used until now for such biotechnological interfaces, is soft, light, flexible and highly biocompatible and naturally sensitive to visible light.
The viruses used to deliver the light-sensitive proteins can be engineered to target very specific clusters of brain cells.
Trichromatic vision involves three pigments, called opsins, that are sensitive to different wavelengths of light.

He realised that some of the off-the-shelf equipment used by serious amateurs is sensitive enough to measure the light drop caused by distant transits.
ECONOMIST: Astronomers may have found their first Saturn lookalike
It was equipped with a 3.5m mirror - the largest monolithic mirror ever flown - and three state-of-the-art instruments sensitive to long wavelengths of light, in the far-infrared and sub-millimetre range (55 to 672 microns).
It is an interesting triple "coincidence, " which probably evolved over time, that our eyes are most sensitive to yellow-green light, which happens to be the characteristic color of sunlight as well as the color that can most easily be transmitted through the Earth's atmosphere.
The goal was to substitute photoreceptors with a light-sensitive material capable of restoring photosensitivity to the retina, by easing down the retina on a layer of organic photovoltaic semiconductor.
The sense of immediacy was balanced against what we knew were sensitive techniques that would come to light some day.
Threaded on a wire one-fifth the thickness of a human hair, these tiny seeds of light can be injected to activate special networks of light-sensitive neurons.

Opportunities to photograph Mercury from space are also limited because light sensitive equipment, such as the Hubble Space Telescope, are not allowed to look at objects close to the Sun, such as Mercury or Venus.
Though lawyers for dioceses facing bankruptcy have fought to keep most financially sensitive documents sealed, the process has forced the church to let in unaccustomed light.
The great advantage of a more light-sensitive camera is that you can make radical adjustments to the aperture, allowing filmmakers to indulge in what's become known as "bokeh porn" shallow depth-of-field shots in which sharply defined subjects are placed against artily smeared backgrounds.

In light of the posting of sensitive security information on the web, TSA sought to identify where the information came from.
Though his comments are limited to that case and not intended to provide general guidance, they nevertheless shed some light on a hugely complex and sensitive issue.
ECONOMIST: A little guidance on when the law will be strictly applied
Depending on just how researchers tailor the virus that carries the light-sensitive protein, they now can target almost any type of neuron they want to study.
WSJ: Scientists Cast Light Onto Roots of Illness Deep in the Brain
Problems included a penchant for picking up dirt and fingerprints (the price you pay for a beautiful glossy face, we suppose), a cramped nav key layout with the tricky touch-sensitive Navi Wheel front and center, audio performance that wasn't bad but was expected to be far better in light of the dedicated DSP, and a "shovel"-like feel in the hand, a symptom of the phone's generous dimensions.
