Monoclonal antibody fragment treatments for 'wet' macular degeneration keep elderly drivers behind the wheel, study suggests
- ScienceDaily
- 12/10/2 20:34
The advanced neovascular, or "wet," form of age-related macular degeneration (AMD), left untreated, is the most common cause of vision loss among the elderly and a leading reason for their loss of driving privileges. But results of a new study suggest that monthly injections of ranibizumab improve eye chart test results required for a driver's license, build driver confidence and keep those with...

Scientists team with U.S. Coast Guard to explore ice-free Arctic Ocean
- ScienceDaily
- 12/10/2 20:32
With the melting ice in the Arctic, U.S. Coast Guard crews based in Alaska have taken on a new challenge: carefully deploying scientific equipment through cracks in the ice from an airplane hundreds of feet in the air. It's all part of a new partnership that has evolved since disappearing Arctic ice has opened vast new frontiers -- for the Coast Guard and for University of Washington scientists....
Warning, automatic braking systems on autos will help save lives, researchers predict
- ScienceDaily
- 12/10/2 20:32
Researchers extracted 1,396 incidents of rear-end collisions from a national U.S. database and looked at them on a case-by-case basis to determine whether the intelligent vehicle systems being studied would have been called into play and, if so, how they would have helped. The research showed that 7.7 percent of crashes would be prevented by use of all three systems -- warning, assisted braking,...
A novel function for p27 protein in the control of interneuron migration in the developing cerebral cortex
- ScienceDaily
- 12/10/2 17:34
These results by GIGA-Neurosciences researchers (University of Liège, Belgium) increase our understanding of the mechanisms that drive neuronal migration in the cerebral cortex. Disruption of neuronal migration is associated with various neurological disorders characterized by mental retardation, epilepsy, learning disabilities, or...
New findings on the workings of the inner ear
- ScienceDaily
- 12/10/2 17:34
The sensory cells of the inner ear have tiny hairs called stereocilia that play a critical part in hearing. It has long been known that these stereocilia move sideways back and forth in a wave-like motion when stimulated by a sound wave. After having designed a microscope to observe these movements, a research team in Sweden has discovered that the hairs not only move sideways but also change in...
Children's bicycle helmets effective in impact and crush tests, study suggests
- ScienceDaily
- 12/10/2 16:15
To determine the effectiveness of bicycle helmet use, scientists tested how well helmets withstood forces of impact and crush tests when covering human cadaver skulls. They found that helmet use can substantially reduce (by up to 87%) the acceleration experienced by the skull during an impact and can aid the skull in resisting forces up to 470 pounds in a crush...
Concussion spectrum in college athletes wearing helmets: 'Not so simple,' say researchers
- ScienceDaily
- 12/10/2 16:15
Much has been written in recent years about the short- and long-term consequences of concussions sustained in sports, combat, and accidents. However, there appear to be no steadfast rules guiding the definition of concussion. Researchers investigated the signs, symptoms, and clinical histories used by athletic trainers to define concussion in individual college athletes engaged in contact sports....
