Effective New Spectroscopy for Searching Extraterrestrial Life

Researchers have developed a new instrument, which improves on an analytical technique known as micro Raman spectroscopy. This technique uses the interaction between laser light and a sample to provide chemical composition information on a microscopic scale. It can detect organic compounds such as the amino acids found in living things and identify minerals formed by biochemical processes on Earth that might indicate life on other planets. This study got published in The Optical Society Journal Applied Optics.

Diabetic Blindness Could be Reversed, Study Finds

Johns Hopkins researchers found that increased vascular endothelial growth factor ( VEGF)  levels in the retina attract white blood into the retina , where they adhere to the walls of blood vessels, disrupting blood flow. Reducing VEGF or blocking it with an antibody caused the white blood cells to dissipate, opening the closed vessels and restoring blood flow to the area. The study published in the Journal of Clinical Investigation Insight
