Controlling corneal blindness by 2030: an interview with Dr Pravin Vaddavalli

Corneal blindness is estimated to be the second most prevalent cause of blindness in many less developed countries. Globally, bilateral corneal blindness is estimated to afflict 4.9 million persons and accounts for 12% of 39 million blind, utilizing WHO 2010 global blindness data.

New qPAINT technology helps develop more precise, less expensive microscopes

Knowing the exact number of molecules located at specific junctures in cells can be a critical measure of health as well as disease. For example, abnormally high numbers of growth factor receptors on cells can be an indication of cancerous and precancerous states; specific proteins located at the junction where neurons connect in the brain may affect brain function as they accumulate or disperse.

Enhancing motility of skin cells could help promote wound healing

Skin cells typically spend their entire existence in one place on your body. But Washington State University researchers have seen how the cells will alter the proteins holding them in place and move to repair a wound.

OIST scientists reveal how big protein complex inside E. coli cells divide and multiply

Escherichia coli (E. coli) are bacteria that live all around and inside of us. Most E. coli are harmless, but some strains can cause illness, and can even, in extreme cases, be deadly. With recent outbreaks of E. coli around the world, there is a fear of acquiring an infection from these bacteria.

Miniature microscope helps neuroscientists identify how the brain links different memories over time

Using a miniature microscope that opens a window into the brain, UCLA neuroscientists have identified in mice how the brain links different memories over time. While aging weakens these connections, the team devised a way for the middle-aged brain to reconnect separate memories.
