Google Glass gave the idea of data glasses an uphill cultural hill to climb - rather than being a must-have accessory, they became a source of derision.

A risk gene for dyslexia is associated with impairments in visual motion detection, according to a study published May 27 in The Journal of Neuroscience. Mutations in the gene DCDC2 have previously been associated with dyslexia, and this study found that dyslexics with an altered copy of the gene are unable to detect certain types of visual motion.

• The researchers used a series of visual tests to compare typical readers with two groups of dyslexics -- one with and one without a specific deletion in the DCDC2 gene.

A recent study has revealed a breakthrough in asthma research might be on the horizon. Following extensive research carried out across a number of institutions, it has been discovered that protein molecules - known as calcium-sensing receptors - have a vital role in asthma. Although they have not previously been used to treat asthma, there is already medication available (calcilytics) that could be used to block these proteins.

In asthmatics, the immune system essentially misidentifies harmless substances, such as pollen for example, as a threat. The airways then restrict in an attempt to keep the ‘harmful’ substances from entering the lungs leading to the body facing constricted airways and, therefore, less ability to breathe properly.

About 2.5 billion people worldwide don't have access to sanitary toilets. Latrines are an option for many of those people, but these facilities' overwhelming odors can deter users, who then defecate outdoors instead. To improve this situation, fragrance scientists paired experts' noses and analytical instruments to determine the odor profiles of latrines with the aim of countering the offensive stench. Their report appears in the ACS journal Environmental Science & Technology.

A global-scale study has estimated how forest emitted compounds affecting cloud seeds via formation of low-volatility vapours. According to the latest projections, terrestrial vegetation emits several million tons of extremely low-volatility organic compounds (ELVOCs) per year to the atmosphere.

U.S. Congress members' social circles are more important in how they vote than their liberal or conservative beliefs or constituents' opinions, according to a new model of voting behavior created by Dartmouth College researchers.

The study appears in the journal Research & Politics. A PDF is available on request.

The standard model of voting behavior basically assumes there is only one factor that matters: where a legislator lives on the liberal-conservative axis. That position, derived from their roll call votes, serves as an ideological marker that presumably summarizes the various forces that can influence the legislators' votes, including personal preferences, party preferences and constituent opinion.
