Electric vehicles are all the rage for wealthy elites but they have a more practical future benefit - mass transit, assuming the electricity source is low-emission like nuclear or solar. 

Right now, things like electric buses require more cost because of the maintenance and downtime. They take huge batteries, which means when those die off and they are placed into landfills we will replace global warming with acid rain. And to match gasoline's energy density would take a battery larger than could fit on a bus. 

The solution instead has to be much faster charging times. 

Passwords have to be complicated in order to keep them from being stolen but our reactions to words are subjective - and those could lead to the best security of all.

In a new study, researchers from Binghamton University observed the brain signals of 45 volunteers as they read a list of 75 acronyms, such as FBI and DVD. They recorded the brain's reaction to each group of letters, focusing on the part of the brain associated with reading and recognizing words, and found that participants' brains reacted differently to each acronym, enough that a computer system was able to identify each volunteer with 94 percent accuracy. The results suggest that brainwaves could be used by security systems to verify a person's identity. 

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.

The UK’s onshore wind power industry may have been dealt a huge blow by new government policies announced last week, but this apparent setback should instead be seen as an opportunity. Elsewhere in Europe local, cooperative wind power is flourishing – could your town be next?

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.

Earlier in the year the world was finally treated to some good news from science: a report was published that claimed to show that eating chocolate could help you lose weight faster.

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.

Haskell Karp was 37 when he suffered his first heart attack, and over the next ten years he suffered a variety of related problems. By 1969 even the slightest effort, like combing his hair or brushing his teeth, would bring on chest pain or extreme shortness of breath.
