Red Lights At Night Better Than White When It Comes To Mood

Brett Smith for redOrbit.com - Your Universe Online People working the graveyard shift may want to literally see red because according to a new study -- the color of light animals are exposed to at night can affect mood regulation. Study researchers from The Ohio State University found hamsters that were exposed to blue lights at night experienced the worst mood disruptions, followed closely by white lights, when compared to hamsters that spent their nights in a dim red light. "Our...

Among the animals that are appealing “cover models” for scientific journals, lancelets don´t spring readily to mind. Slender, limbless, primitive blobs that look pretty much the same end to end, lancelets “are extremely boring. I wouldn´t recommend them for a home aquarium,” says Enrico Nasi, adjunct senior scientist in the MBL´s Cellular Dynamics Program. Yet Nasi and his collaborators managed to land a lancelet on the cover of The Journal of...

New research in the FASEB Journal provides insight into the molecular basis of one form of retinal degeneration, Enhanced S-Cone Syndrome also known as Goldman-Favre Syndrome A new research report published in The FASEB Journal (https://www.fasebj.org) will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome. In the...

Creatures are not born hardwired to see. Instead, they depend on electrical activity in the retina to refine the complex circuits that process visual information. Two new studies from Brown University in different species using different techniques show how nascent animal brains use light to wire up or construct their central vision system. Any parent knows that newborns still have a lot of neurological work to do to attain fully acute vision. In a wide variety of nascent animals, genes...

Retinitis pigmentosa affects over one million people worldwide and is manifested by a progressive loss of sight, eventually leading to blindness. Retinitis pigmentosa is a form of inherited retinal degeneration that affects the light-sensitive cells : photoreceptors. Photoreceptors are a special type of neuron which convert light into nervous impulses. These impulses are then processed by the retina and transmitted along the nerve fibres to the brain. There are two types of photoreceptors:...

Like a wristwatch that needs to be wound daily for accurate time-telling, the human circadian system "” the biological cycles that repeat approximately every 24 hours "” requires daily light exposure to the eye's retina to remain synchronized with the solar day. In a new study published in the June issue of Neuroscience Letters, researchers have demonstrated that when it comes to the circadian system, not all light exposure is created equal.The findings have profound implications...

Researchers have discovered that a set of light-responsive retinal cells that form connections to the circadian clock are functional very early in development, from the day of birth. Although the cells are sensitive to light, they do not participate in image formation, a process that matures later on. The work has been reported in the journal Current Biology by Sumathi Sekaran, of Imperial College London, and colleagues there and at John Hopkins University and the University of Manchester....
