Plant growth without light control: Synthetic photoreceptor stimulates germination and development
Plants are dependent on the sun. Sunlight does not only supply them with energy, but also controls their development steps. So-called photoreceptors activate the processes of germination, leaf development, ...

Scientists solve mystery of the eye
(PhysOrg.com) -- Scientists have a good overall understanding of human vision: when light enters our eyes, it is focused by the lens and strikes the retina in the back of the eye. The light causes some of ...

Protein plays role in helping plants see light
Plants do not have eyes or legs, yet they are able to "see" and move toward and away from light. This ability, called phototropism, is controlled by a series of molecular-level signals between proteins inside and between ...

Finding is a feather in the cap for researchers studying birds' big, powerful eyes
Say what you will about bird brains, but our feathered friends sure have us -- and all the other animals on the planet -- beat in the vision department, and that has a bit to do with how their brains develop.

Nanosized diamonds enable progress in retinal prostheses
Research groups in several countries are making progress in retinal prosthesis development. If they achieve their aims, patients who have gone blind, due to loss of their photoreceptors, could recover a better ...

Light-sensing receptor plays role in temperature sensation: study
A light-sensing receptor that's packed inside the eye's photoreceptor cells has an altogether surprising role in cells elsewhere in the body, Johns Hopkins scientists have discovered. Using fruit flies, they showed that this ...

Modeling retinitis pigmentosa with iPS cells
Retinitis pigmentosa (RP) is a cluster of genetically determined eye disorders that cause visual defects such as night blindness and narrowing of the field of vision, due to progressive loss of rod photoreceptors. ...
