When first responders arrived to the burning home on Eugene Street in Manchester, New Hampshire just after 2 am on January 27, half the home was already up in flames. It was a big fire, but relatively routine: Working in the dark, the firefighters made sure the two residents got out unharmed, and got to work.

The Amazon forest stores about half of the global tropical forest carbon and accounts for about a quarter of carbon absorption from the atmosphere by global forests each year. As a result, large losses of Amazonian forest cover could make global climate change worse.
In the past, researchers have found that a large part of the Amazon forest is susceptible to a tipping point. The tell-tail sign is satellite data showing areas of savannah and rainforest coexisting under the same environmental conditions. Theories from nonlinear dynamics would then suggest that both states are alternative stable outcomes. This so called bistability means that shocks such as forest clearance or drought could lead to a dramatic increase of fire occurrence and tip an area of rainforest into savannah. Areas that have experienced this transition would then remain locked into this savannah state until large enough increases of rainfall and release of human pressures allow forests to regrow faster than they are lost by intermittent fires.

GOES-16, the most advanced weather satellite NOAA has ever developed, will be moved to the GOES-East position at 75 degrees west longitude, once it is declared operational in November. Top officials from NOAA announced the long-awaited decision at today’s 2017 Atlantic Hurricane Season Outlook news conference in College Park, Maryland.

We all know that washing our hands can keep us from spreading germs and getting sick. But a new Rutgers-New Brunswick study found that cool water removes the same amount of harmful bacteria as hot.
“People need to feel comfortable when they are washing their hands but as far as effectiveness, this study shows us that the temperature of the water used didn’t matter,” said Donald Schaffner, distinguished professor and extension specialist in food science.

Beekeepers across the United States lost 33 percent of their honey bee colonies during the year spanning April 2016 to April 2017, according to the latest preliminary results of an annual nationwide survey. Rates of both winter loss and summer loss—and consequently, total annual losses—improved compared with last year.
Total annual losses were the lowest since 2011-12, when the survey recorded less than 29 percent of colonies lost throughout the year. Winter losses were the lowest recorded since the survey began in 2006-07.
The survey, which asks both commercial and small-scale beekeepers to track the survival rates of their honey bee colonies, is conducted each year by the nonprofit Bee Informed Partnership in collaboration with the Apiary Inspectors of America. Survey results for this year and all previous years are publicly available on the Bee Informed website.

Worldwide, three new cars roll off the line every second – that’s 73 cars and 18 million utility vehicles per year. Most run on gasoline. In industrialized nations, the trend is moving towards so-called downsizing engines: smaller but with direct gasoline injection and turbocharging. This technology is kind to the environment and saves fuel, the manufacturers say. Experts estimate that by 2020, 50 million of these direct-injection gasoline engines will be running on the roads all over Europe – high time the cocktail of exhaust emissions from these engines were examined closely.
