AFB announces Access Award recipients for 2012

What do the leaders of "America's pastime," a free open-source screen-reading software company, an orientation and mobility (O&M) program, and the founder of Camp Abilities have in common? All have taken successful strides toward creating a better quality of life for people who are blind or visually impaired, which is why they were named the recipients of the 2012 Access Awards, announced today by the American Foundation for the Blind.

Moderate alcohol in family setting can prevent young people from binge drinking: Study

Italian youths whose parents allowed them to have alcohol with meals while they were growing up are less likely to develop harmful drinking patterns in the future, according to a new study led by a Boston University School of Public Health (BUSPH) researcher.

Obesity and severe obesity continue to rise among U.S. adults

Obesity and severe obesity continued to grow among adults in the United States between 2007-2008 and 2015-2016 but there were no significant overall changes among youth.

Confocal light sheet microscopy yields high-resolution views of brain's neural pathways

Shortly after the Hubble Space Telescope went into orbit in 1990 it was discovered that the craft had blurred vision. Fortunately, Space Shuttle astronauts were able to remedy the problem a few years later with supplemental optics. Now, a team of Italian researchers has performed a similar sight-correcting feat for a microscope imaging technique designed to explore a universe seemingly as vast as Hubble's but at the opposite end of the size spectrum—the neural pathways of the brain.

Novel graphene oxide-based biosensor may speed up development of new drugs against HIV, cancer

Longing to find a cure for cancer, HIV and other yet incurable diseases, researchers have already tried out hundreds of drugs, each requiring preclinical and clinical testing with live subjects. How many chemical agents more to try? Moving at such rate, will we find the cure during our lifetime? One of the easiest ways to speed up the drug development process is to simply perform it outside of the living body (e.g., by watching the substances react with the smallest pieces of live tissue and thus quickly predicting the overall effect it will make to the body when inside).
