Nearsightedness, or myopia, is an increasing problem around the world. There are now twice as many people in the US and Europe with this condition as there were 50 years ago. In East Asia, 70 to 90 percent of teenagers and ...

Turning viruses into molecular Legos

Researchers at the University of California, Berkeley, have turned a benign virus into an engineering tool for assembling structures that mimic collagen, one of the most important structural proteins in nature. The process ...

Eye blinking on-a-chip

Researchers at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS) have developed a device that moves fluids over corneal cells similarly to the movement of tears over a blinking eye. The scientists ...

3-D printed artificial corneas similar to human ones

When a person has a severely damaged cornea, a corneal transplant is required. However, there are 2,000 patients waiting for the cornea donation in the country as of 2018, and they wait for six or more years on average for ...

Aggregation of proteins in cells may result in diseases

Changes in the structure of proteins can lead to various diseases, such as Alzheimer's, type 2 diabetes and corneal dystrophy. A research team from Aarhus University has now discovered how a particular protein can damage ...

Micro-spectroscopy opens new routes for diagnostics

Just as mechanical properties and chemical compositions of materials are of fundamental importance in buildings, the cells that comprise every living organism have different properties and shapes depending on their function ...
