In the News – Science Line – Stoeckle

Fishing for DNA   “Stoeckle, a molecular biologist at Rockefeller University, is experimenting with a relatively new technique for understanding what lives in or near a particular body of water. It’s the equivalent of scat sampling and other methods that … More »

In the News – New Scientist – Ausubel

Earth’s rarest minerals could hint at life on other planets   “Two-thirds of rare minerals arise as a consequence of biological processes, such as biomineralisation, the authors say. These minerals could shed light on the co-evolution of biology and geology. … More »

DNA testing by high school students shows many teas contain unlisted ingredients

Unlisted ingredients identified by DNA barcoding technology include weeds such as annual bluegrass and herbal plants such as chamomile. Though mostly harmless, the surprise ingredients could affect a tiny minority of consumers with acute allergies. More »

The Great Reversal, an increase in forest density worldwide, is under way

A new study by scientists at Rockefeller University and colleagues in the United States and Finland challenges measurements of carbon storage based on forest area alone. Several national increases of density and/or area signal the Great Reversal is under way in forests globally after centuries of loss and decline. More »

Intensity of human environmental impact may lessen as incomes rise, analysis suggests

The richer you are, the more of the world’s resources you can afford to consume. But in many parts of the world, rising incomes are not having the proportionate effect on energy consumption, croplands and deforestation that one might expect, a new 25-year study shows. More »

DNA barcoding uncovers likely new species of birds and bats

In the first effort to ever “barcode” species on a continental scale, scientists have completed a pilot study of U.S. and Canadian birds that suggests that 15 new genetically distant species have been overlooked in centuries of bird studies. The research validates DNA “barcoding” as an efficient means of identifying species based on just a tiny sample of biological material, and it has implications for environmental research as well as for reducing contamination in our food supply and preventing collisions between aircraft and birds.
