Pollution-heart disease tie revealed
U. MICHIGAN (US) — Digital photographs of the tiny, hair-like blood vessels in the back of the eye, reveal how small blood vessels, like those that bring blood to the heart, respond to air pollution. (more…)

How retina’s hardware processes color
NYU (US)—Biologists have identified, in greater detail, how the retina’s cellular hardware is used in color preference. The work enhances our understanding of how eyes and the brain process color. (more…)

Glaucoma’s blindness starts in the brain
VANDERBILT (US)—The first sign of injury in glaucoma occurs in the brain, not the eye as previously thought. A new study shows glaucoma is very much like other central nervous system diseases. (more…)

Zebrafish do it. Why can’t we?
U. MICHIGAN (US)—Biologists long have marveled at the ability of some animals to re-grow lost body parts—newts regrow legs and zebrafish re-grow fins—and even repair damaged heart and eye tissue. Now researchers have discovered that some of the same genes underlie the process in different types of tissues. (more…)

‘Dark cells’ of living retina imaged for first time
U. ROCHESTER (US)—In a quest to figure out why one of the most prevalent eye diseases actually happens, researchers have captured the first-ever images of “dark cells” in a living retina. The new technique for seeing this nearly invisible layer of cells could help doctors identify the onset of many diseases of the eye, including macular degeneration, long before a patient notices symptoms.
