Insights from color-blind octopus help fight human sight loss

University of Bristol research into octopus vision has led to a quick and easy test that helps optometrists identify people who are at greater risk of macular degeneration, the leading cause of incurable sight loss.

Customized programming of human stem cells

Induced pluripotent stem cells (iPS) have the potential to convert into a wide variety of cell types and tissues for drug testing and cell replacement therapies. However, the "recipes" for this conversion are often complicated ...

Optical coherence tomography shines with a new type of contrast

A diagnostic workhorse, optical coherence tomography (OCT), provides high-resolution 3-D imaging of subsurface tissue structures. Most likely, for your last eye exam, the ophthalmologist took cross-sectional pictures of your ...

A device for the early detection of certain eyesight problems

EPFL researchers have developed a device that can zoom in on previously invisible cells at the back of the eye. The technology could be extremely useful for ophthalmologists, in particular for detecting age-related macular ...

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, ...
