NASA's Mars Curiosity rover has measured a tenfold spike in methane, an organic chemical, in the atmosphere around it and detected other organic molecules in a rock-powder sample collected by the robotic laboratory's drill. "This temporary increase in methane -- sharply up and then back down -- tells us there must be some relatively localized source," said Sushil Atreya of the University of Michigan, Ann Arbor, a member of the Curiosity rover science team. "There are many possible sources, biological or non-biological, such as interaction of water and rock."

The role of taxes (and EV's) in reducing CO2 emissions from cars in Europe analyzed
The Netherlands had the lowest CO2 emissions from new cars in the European Union last year, thanks to its tax regime favouring fuel economy and low-carbon vehicles.
Germany and Poland are among the countries with the highest C02 emissions from new cars and the weakest national tax policies, a report by NGO Transport & Environment has found.
Cars are responsible for 15% of Europe’s total CO2 emissions and are the single largest source of emissions in the transport sector.
New York fracking ban has broader implications for America
After years of public pressure, New York today became the second state to ban hydraulic fracturing because of risks to people and the environment. The announcement from Gov. Andrew Cuomo adds to the pressure on the Obama administration to end fracking across the country, including on America’s public lands.
“New York just took a huge leap forward in protecting its people and wildlife from the dangers of fracking,” said Kassie Siegel of the Center for Biological Diversity. “Now it’s time for other leaders to follow, including President Obama and Gov. Jerry Brown in California.”
Crows join rank of species that exhibit advanced relational thinking
Next to humans, other species in the animal kingdom such as apes and monkeys have exhibited advanced relational thinking. But are there others? The newest species to join this list of highly intelligible animals? Crows.
New process turns biomass 'waste' into chemical products
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel for racecars and jets. A team of researchers from Purdue University's Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities. Lignin is a tough and highly complex molecule that gives the plant cell wall its rigid structure.
Study finds reefs reduce wave energy by 97%
We have a lot of stake in the coast. Coastal waters are where we host fisheries, build homes and turn to for tourism and recreation. So how should coastal communities, which comprise nearly 40 percent of the world's population, safeguard against flooding, erosion and violent weather? Marine scientist Michael Beck suggests the solution is growing right beneath some waves and, in many cases, it has been waiting there for thousands of years.
