OCT Angiography Advantageous over Conventional Techniques for Detecting Causes of Blindness

Research published today in the Proceedings of the National Academy of Sciences (PNAS) demonstrates that technology invented by researchers at Oregon Health & Science University's Casey Eye Institute can improve the clinical management of the leading causes of blindness. Optical coherence tomography (OCT) angiography could largely replace current dye-based angiography in the management of these diseases.

2D IR Spectroscopy Helps Study Therapeutic Mechanism of Anti-Viral Drug

A newly developed spectroscopy method is helping to clarify the poorly understood molecular process by which an anti-HIV drug induces lethal mutations in the virus's genetic material. The findings from the University of Chicago and the Massachusetts Institute of Technology could bolster efforts to develop the next generation of anti-viral treatments.

Novel Technique Reduces Halo Effect Generated Using Multifocal Lenses

In a recent study published in Optics Communications, scientists from Bar-Ilan University in Israel have presented a new technique that significantly reduces the halo effect that is generated when using multifocal (contact and intra-ocular) lenses and looking at bright point sources in dark conditions.

Scientists Uncover Atomic Structure of Light-Driven Ion Pump

Scientists from Jülich, Grenoble, Frankfurt and Moscow uncovered the atomic structure of KR2, a light-driven transporter for sodium ions which had only recently been discovered. Based on the structural information the team then identified a simple way to turn KR2 from a sodium- into a potassium pump using simple means. Integrated into neurons, this could make KR2 a valuable tool for optogenetics, a new field of research that uses light-sensitive proteins as molecular switches to precisely control the activity of neurons and other electrically excitable cells using light impulses.
