How can accidental captures of loggerhead turtles be reduced?
03/18/2010 - 04:00
Scientists have studied interactions between the loggerhead turtle (Caretta caretta) and fishing gear such as longline hooks used at the water surface, mass beachings, and the effects of climate change on these animals. In order to reduce captures of this marine species without causing economic losses for fishermen, the scientists are proposing that fishing in the summer should only be carried out by night and in areas more than 35 nautical miles from land.

Giant sequoias yield longest fire history from tree rings
03/17/2010 - 23:00
A 3,000-year record from 52 of the world's oldest trees shows that California's western Sierra Nevada was droughty and often fiery from 800 to 1300, according to new research. Scientists reconstructed the region's history of fire by dating fire scars on ancient giant sequoia trees, Sequoiadendron giganteum, in the Giant Forest of Sequoia National Park. Individual giant sequoias can live more than 3,000 years and are considered the world's largest trees by volume.

Beluga sturgeon in Caspian Sea reclassified as 'critically endangered'
03/17/2010 - 23:00
Beluga sturgeon in the Caspian Sea have been reclassified as "critically endangered" placing them on IUCN's Red List, providing strong evidence that fishing and international trade should be halted and a stock-rebuilding plan should be initiated immediately. Beluga sturgeon populations have been decimated in part due to unrelenting exploitation for black caviar -- the sturgeon's unfertilized eggs -- considered the finest in the world.

Sticky environmental problem with carpet tiles solved
03/17/2010 - 23:00
A new adhesive for use in carpet tiles could help dramatically reduce their impact on the environment. The powerful adhesives currently used to bind the layers of carpet tiles together make it challenging to recycle them. In Europe, around 70 million kilograms of carpet tile waste is incinerated or sent to landfill sites every year.
