Age-related macular degeneration before and after the era of anti-VEGF drugs

Science News Daily - May 2, 2016 - 8:54pm
In a study of nearly 650 people with the eye disease age-related macular degeneration (AMD), half still had vision 20/40 or better, typically good enough to drive or to read standard print, after five years of treatment with anti-VEGF drugs that are injected into the eye. The authors of the study say those outcomes would have been unimaginable about 10 years ago, prior to the drugs' availability.

Californian sudden oak death epidemic 'unstoppable'

Science News Daily - May 2, 2016 - 3:11pm
New research shows the sudden oak death epidemic in California cannot now be stopped, but that its tremendous ecological and economic impacts could have been greatly reduced if control had been started earlier. The research also identifies new strategies to enhance control of future epidemics, including identifying where and how to fell trees, as 'there will be a next time.'

Psychiatric symptoms impact mental health court engagement

Science News Daily - May 2, 2016 - 2:06pm
People living with mental illness are overrepresented in the criminal justice system. Interventions to help this population, such as mental health courts, are becoming popular across the country. New research finds that for mental health courts to be successful, every professional engaged in the process should be aware of the relationship between psychiatric symptoms and participant engagement within the system and connect participants with comprehensive treatment and services as early as possible.

Although boiling, water does shape Martian terrain

Science News Daily - May 2, 2016 - 12:15pm
At present, liquid water on Mars only exists in small quantities as a boiling liquid, and only during the warmest time of day in summer. Its role has therefore been considered insignificant until now. However scientists have now shown that even though water that emerges onto the surface of Mars immediately begins to boil, it creates an unstable, turbulent flow that can eject sediment and cause dry avalanches. The flow of small amounts of a boiling liquid therefore significantly alters the surface.
