Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...

Could young blood hold secrets to longer, healthier life?

In what sounds like a scene from a science fiction movie, researchers in 2005 stitched together old and young mice so they shared a circulatory system. Youthful blood seemingly rejuvenated many tissues of the elderly rodents, ...

Laser-based technology helps doctors image full eye in 3-D

It is estimated that in 2015, 217 million people had moderate to severe vision impairment, while 36 million were blind, according to an article in the journal The Lancet Global Health. The World Health Organization predicts ...

Why wasn't the human genome shredded long ago?

In the January 7th edition of Communications Biology, researchers at InsideOutBio argue that an unusual form of DNA with a reverse twist may have helped thwart the invasion of the human genome by junk DNA. This mechanism ...

Chemists discover how blue light speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye's retina into cell killers, according to optical chemistry research at The University of Toledo.

Scientists turbocharge high-resolution, 3-D imaging

You may not have heard of optical coherence tomography, or OCT. But if you've visited an ophthalmologist recently, chances are your eye came within an inch or two of a scanning device employing the technology. Tens of thousands ...

Potatoes with great potential for added value

The potato is not only a basic food item and one of the main food crops worldwide, it contains a huge variety of minerals and phytochemicals with potentially health-promoting effects. Greater awareness about the importance ...

A first glimpse into disc shedding in the human eye

An elusive biological cycle in the eye - the daily disposal and regeneration of the end tips of photoreceptor cells - has been captured in images for the first time in a living human eye. Photoreceptors are light-sensitive ...
