Jackdaws flap their wings to save energy
For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists at Lund University in Sweden have now shown that jackdaws minimise their energy consumption when they lift off and fly, because the feathers on their wing tips create several small vortices instead of a single large…

Night vision for bird- & bat-friendly offshore wind power
The same technology that enables soldiers to see in the dark can also help protect birds and bats near offshore wind turbines.Night vision goggles use thermal imaging, which captures infrared light that's invisible to the human eye. Now, researchers at the Department of Energy's Pacific Northwest National Laboratory are using thermal imaging to help birds and bats…

Global Warming Will Leave Different Fingerprints on Global Subtropical Anticyclones
Subtropical anticyclone is an essential component of the atmospheric circulation in the subtropics, and it is responsible for the formation of subtropical monsoons and deserts. There are two subtropical anticyclones in the subtropical northern hemisphere in boreal summer, and three subtropical anticyclones in the subtropical southern hemisphere in austral summer. These five summertime subtropical anticyclones…

Climate change shifts timing of European floods
A study conducted by TU Wien and 30 European partners shows that the timing of the floods has shifted across much of Europe, dramatically in some areas. When a major flood event occurs it is often attributed to climate change. However, a single event is not proof, and so far it has been unclear whether…

Crank the AC, cut in-car pollution
For many, the commute to and from work is a lengthy, stressful process. According to the U.S. Census Bureau, it takes the average American about 26½ minutes to get to work. That’s nearly an hour each day — to work and back — to face traffic snarls and congested highways. That commute can also be…

Underwater noise pollution stresses and confuses fish
Researchers at Newcastle University found that European sea bass experienced higher stress levels when exposed to the types of piling and drilling sounds made during the construction of offshore structures.The fish also showed signs of being confused when they encountered a potential predator while exposed to these underwater noises. When researchers played recordings of piling…

Pesticides Prevalent in Midwestern Streams
One hundred small streams in the Midwest were tested for pesticides during the 2013 growing season and found to contain, on average, 52 pesticides per streamMore than 180 pesticides and their by-products were detected in small streams throughout 11 Midwestern states, some at concentrations likely to harm aquatic insects, according to a new study by…

U.S. had 2nd warmest year to date and 10th warmest July on record
July is the hallmark of summer in the United States. Long days, intense sun and high humidity typically make it the hottest month of the year. The heat can also trigger flash droughts, wildfires and summer storms. This July didn’t disappoint.Here’s how July and the year to date fared in terms of the climate record.

New Technique Offers Clues to Measure Ocean Deoxygenation
The living, breathing ocean may be slowly starting to suffocate. More than two percent of the ocean’s oxygen content has been depleted during the last half century, according to reports, and marine “dead zones” continue to expand throughout the global ocean. This deoxygenation, triggered mainly by more fertilizers and wastewater flowing into the ocean, pose…
