New amphibious centipede species discovered in Okinawa and Taiwan

"...Tokyo, Japan - Researchers from Tokyo Metropolitan University and Hosei University have discovered a new species of large, tropical centipede of genus Scolopendra in Okinawa and Taiwan. It is only the third amphibious centipede identified in the world, and is the largest in the region, 20 cm long and nearly 2 cm thick. It is also the first new centipede to be identified in Japan in 143 years, testament to the incredible biodiversity of the Ryukyu Archipelago..."

Reliably measuring whether rivers or lakes run out of air

"...Using the conventional measurement method, water samples are mixed with the chemicals permanganate or dichromate. These are especially reactive and break down all organic substances in a short time. The quantity of consumed permanganates or dichromates can then be used to determine how much organic substance was contained in the water sample..."

New study: Thick sea-ice warms Greenland fjords

"...Summertime melt produces a warm freshwater layer floating atop saltier water in the fjord; here the sea-ice barrier trapped this meltwater inside the fjord. Because of the difference in salt content, the surface water became isolated also from the water below, allowing time for intense solar heating of the fresher surface water. Such warmer water temperatures can contribute to faster melting of the Ryder Glacier in Sherard Osborn Fjord, as well as changing the biogeochemistry in the fjord waters..."

Road salts and other human sources are threatening world's freshwater supplies

"...Previous studies by Kaushal and his team showed that added salts in the environment can interact with soils and infrastructure to release a cocktail of metals, dissolved solids and radioactive particles. Kaushal and his team named these cascading effects of introduced salts Freshwater Salinization Syndrome, and it can poison drinking water and cause negative effects on human health, agriculture, infrastructure, wildlife and the stability of ecosystems..."

A sun reflector for earth?

"..."Participating in this working group has been quite eye-opening for me," said co-author Peter Groffman, an ecosystem ecologist at the Advanced Science Research Center at The Graduate Center, CUNY and the Cary Institute of Ecosystem Studies. "I was unaware that modeling climate intervention was so advanced, and I think that climate modelers were unaware of the complexities of the ecological systems being affected. It is a strong reminder of the importance of the need for multi-disciplinary analysis of complex problems in environmental science..."

To intervene or not to intervene? That is the future climate question

"...The costs and technology needed to reflect the sun's heat back into space are currently more attainable than other climate intervention ideas like absorbing carbon dioxide from the air. The working group anticipates its discussions and open access paper will encourage an explosion of scientific investigation into how a climate intervention strategy known as solar radiation modification, or SRM, in tandem with greenhouse gas emissions reduction, would affect the natural world..."
