ETH Zurich researchers have successfully created an optical transistor from a single molecule. This has brought them one step closer to an optical computer. Internet connections and computers need to be ever faster and more powerful nowadays. However, conventional central processing units (CPUs) limit the performance of computers, for example because they produce an enormous amount of heat.

Video from portable cameras is analysed to calculate the distance of obstacles and predict the movements of people and cars. This information is then transformed and relayed to a blind person as a three-dimensional 'picture' of sound. The concept is apparently simple and two prototypes have been successfully tested. Laser and digital video cameras become the eyes for the blind man and see the objects and activity going on around him.

Genentech, Inc. announced today that the Phase III study BRAVO showed Lucentis® (ranibizumab injection) improved vision, as measured by the primary endpoint of mean change from baseline in best-corrected visual acuity at six months, in patients with macular edema due to branch retinal vein occlusion. The safety profile of Lucentis was consistent with previous experience and no new adverse events related to Lucentis were observed in the study.

Bausch & Lomb Vision Care announces a renewed focus on its ReNu® brand of lens care solutions through a U.S. consumer need-based rebranding effort that introduces eye care practitioners and consumers to ReNu® Fresh Lens Comfort™ and ReNu® Sensitive Eyes®. Additionally, the company has recently established a dedicated U.S.

Researchers at the Peninsula Medical School in Plymouth and Exeter have received a grant of £9,600 from the Northcott Devon Medical Foundation to continue its research into the genetic causes of eye movement disorders. Last year, the team - along with colleagues from the Children's Hospital in Boston (USA) and King's College London - identified a gene that, when mutated, causes Duane syndrome.
