Green Turtle success story More than 70 years after major turtle nesting beaches became protected on the remote UK overseas territory of Ascension Island researchers are now reporting a boom in population numbers.
Scientists from the University of Exeter and Ascension Island Government Conservation Department report that the number of green turtles nesting at the remote South Atlantic outpost has increased by more than 500 per cent since records began in the 1970s.
General Motors, OnStar, EV's and the Smart Grid General Motors is bringing its OnStar-enabled Smart Grid solutions, to one of the largest electric vehicle collaborations to take place within the industry. Eight global automakers, including GM, and 15 electric utilities are working with the Electric Power Research Institute to develop and implement a standardized Smart Grid integration platform.
"One thing that’s missing from most Smart Grid programs is a sense of collaboration," said Tim Nixon, chief technology officer, Global Connected Consumer, GM. "Companies will showcase a meaningful solution, but without widespread acceptance in the industry, its usability is limited. That's what makes this partnership unique."
Turtle Talk: Exactly how do turtles communicate? Turtles comprise one of the oldest living groups of reptiles, with hundreds of species found throughout the world. Many have been well-researched, and scientists know very specific things about their various evolutionary histories, metabolic rates, and the ways in which their sexes are determined. But there was one very obvious thing that has been largely left unknown by science until very recently. Turtles can make sounds.
Do "Fat taxes" work? Specific taxes on sugar, salt or fat do cause reductions in consumption, the European Commission found in a new report. But higher taxes may also merely encourage consumers to go for cheaper products, it warned.
The precise impact of such "fat taxes" on the competitiveness of the European agriculture and food sector still needs to be fully assessed, the report added.
Ozone + Rising Temperatures = Problems for Food Security A new study shows that interactions between increasing temperature and air pollution can be quite significant when it comes to addressing food security. Conducted in part by researchers at MIT, a study looked in detail at global production of four leading food crops — rice, wheat, corn, and soy. It predicts that effects will vary considerably from region to region, and that some of the crops are much more strongly affected by one or the other of the factors
