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 Nature concludes the eye — which depends on light to see — also needs light to develop normally during pregnancy. Scientists say the unexpected finding offers a new basic understanding of fetal eye development and ocular diseases caused by vascular disorders — in particular one called retinopathy of prematurity that can blind premature infants. The research, led by scientists at Cincinnati Children's Hospital Medical Center and the University of...

Connie K. Ho for redOrbit.com — Your Universe Online Researchers have developed an artificial retina with the ability to restore normal vision based on its work on deciphering the retina´s neural code for brain communication. It´s the first of its kind — an effective prosthetic retina device that can accommodate for blindness in mice. The results of the project are a major breakthrough in working to restore vision for the blind. To begin, the scientists from Weill...

OULU, Finland, May 29, 2012 /PRNewswire/ -- - Brand new research findings from Finland published in a peer-reviewed medical journal A recent placebo-controlled study reveals new evidence of trans-cranial bright light's effect to brain functions when administered through the ear. Bright light stimulation was found to increase activity in brain areas related to processing of visual sensory information and tactile stimuli. The findings constitute the first ever published...

OULU, Finland, May 21, 2012 /PRNewswire/ -- More evidence of the effectiveness of bright light directed at the brain A new study by Oulu University found large amounts of a light-sensitive OPN4-protein, melanopsin [http://www.valkee.com/uk/science.html#navigation ], in the human brain. The mood-enhancing influence and circadian pacemaking properties of bright light when administered through eyes has been shown in earlier studies to be based on the OPN4-protein. In those...

Changes in flies parallel human disorder Perelman School of Medicine at the University of Pennsylvania researchers have discovered a mechanism involving the neurotransmitter dopamine that switches fruit fly behavior from being active during the day (diurnal) to nocturnal. This change parallels a human disorder in which increased agitation occurs in the evening hours near sunset and may also be due to higher than normal dopamine levels in the brain. Sundown syndrome occurs in older people...

Biologists and psychologists know that light affects mood, but a new University of Virginia study indicates that light may also play a role in modulating fear and anxiety. Psychologist Brian Wiltgen and biologists Ignacio Provencio and Daniel Warthen of U.Va.'s College of Arts & Sciences worked together to combine studies of fear with research on how light affects physiology and behavior. Using mice as models, they learned that intense light enhances fear or anxiety in mice, which are...

New research from Mount Sinai School of Medicine has discovered that rhodopsin, a pigment of the retina that is responsible for the first events in the perception of light, may also be involved in temperature sensation. This detection had not been revealed in previous studies. The work emerged from a collaboration between the laboratory of Andrew Chess, M.D., Professor in the Departments of Neuroscience, Developmental and Regenerative Biology and Genetics and Genomic Sciences at Mount Sinai,...
