New York -
The 81st Street Station of the NYC Subway contains dozens of glass mosaic murals of living animals in full colour, endangered or extinct land and sea creatures in grey or black, and fossil organisms embedded in the walls at various levels of the station.
Researchers have found some potentially toxic ingredients in samplings from traditional Chinese Medicine (TCM). They also found traces of endangered animals, with the help of new DNA sequencing technology.
A new index, called SAFE (Species Ability to Forestall Extinction), has been developed to help conservationists better understand how close a species may be to extinction and could be used to help determine where to focus limited conservation resources.
