Glaciers in China that are a critical source of water for drinking and irrigation in India are receding fast, according to a new comprehensive inventory. In the short term, retreating glaciers may release greater meltwater, “but it will be exhausted when glaciers disappear under a continuous warming,” says Liu Shiyin, who led the survey for the Cold and Arid Regions Environmental and Engineering Research Institute in Lanzhou.

Scientists studying the distribution of four commercial and recreational fish stocks in Northeast U.S. waters have found that climate change can have major impacts on the distribution of fish, but the effects of fishing can be just as important and occur on a more immediate time scale. The four species studied– black sea bass, scup, summer flounder, and southern New England/Mid-Atlantic Bight winter flounder – have varied in abundance and have experienced heavy fishing pressure at times over the past 40 years. 

Across the country this holiday season, families and friends will gather around fires in woodstoves or fireplaces. But how you build that fire – and what you burn – can have a significant impact on air quality and health, both inside your home and out.

Whether you’re using a woodstove, pellet stove, or your fireplace, seeing smoke from your chimney means your fire isn’t burning efficiently or cleanly as it could. 

Woodsmoke contains fine particles – also called fine particle pollution or PM2.5 -- which can harm the lungs, blood vessels and heart. People with heart, vascular or lung disease, and older adults and children are more at risk. 

Here are some simple tips for building cleaner-burning fires this holiday season:

Carnivorous plants catch and digest tiny animals in order and derive benefits for their nutrition. Interestingly the trend towards vegetarianism seems to overcome carnivorous plants as well. The aquatic carnivorous bladderwort, which can be found in many lakes and ponds worldwide, does not only gain profit from eating little animals but also by consuming algae and pollen grains. This results in survival in aquatic habitats where prey animals are rare, and in increased fitness if the animals and algae are caught in a well-balanced diet. An Austrian research group around Marianne Koller-Peroutka and Wolfram Adlassnig published these results in the respected journal Annals of Botany.

Noise pollution in the ocean is increasingly recognized as harmful to marine mammals, affecting their ability to communicate, find mates, and hunt for food. But what impact does noise have on invertebrates -- a critical segment of the food web? Very few studies have attempted to answer that question. The harder question to answer might be 'How do you measure hearing in ocean invertebrates'? A new study by researchers at Woods Hole Oceanographic Institution and their colleagues examined behavioral responses to sound by cuttlefish, a type of shell-less mollusk related to squid and octopi. The study is the first to identify the acoustic range and minimum sound sensitivity in these animals. Their findings, published in the Journal of Experimental Biology, can help decision makers and environmental managers better understand the impacts of noise in the ocean.
