In  the United States, there are calls from the environmental fringes to put more labels on food - but not for a USDA federal standard label on GMOs, mandatory ones chosen by lobbyists in state governments. 

Labels are political, and everyone says they want more information on labels. But we know few people really read them on food, that is why so many people are fat. And few seem to read them on medicine or, if they do, they still think more will work better.

Do microbes grow differently on the International Space Station than they do on Earth? Results from the growth of microbes collected by citizen scientists as part of Project MERCCURI indicate that most behave similarly in both places - and that is a good news for space travel.

The "wheat belt" and "gold fields" of southern Western Australia are associated with a regional acid saline groundwater system. Groundwaters hosted in the Yilgarn Craton there have pH levels as low as 2.4 and salinities as high as 28%, which have greatly affected bedrock and subsurface sediments. This is manifested above ground as hundreds of shallow, ephemeral acid saline lakes.

In the June issue of GSA Today, Kathleen Benison of West Virginia University and Brenda Bowen of the University of Utah write that the limited volume of groundwater, in combination with its acidity, salinity, and high concentrations of some metals, make southern Western Australia a difficult place for human habitation.

Asking a few thousand Norwegians what they thought about climate change and not providing canned responses to choose from led to answers that were far more nuanced than the simplistic media portrayals that people accept every study or they are climate deniers.

The respondents were drawn from the Norwegian Citizen Panel, and the survey is part of the LINGCLIM project at the University of Bergen. This project is looking at the language used and the interpretations that prevail in the climate-change debate. The survey was carried out in 2013 as an online questionnaire. This kept the costs down, making it possible to collect data from a sample pool of respondents.

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.
