NASA satellite data was used to help monitor the health of Florida's coral reef as part of a field research effort completed this August and September.

The controversial practice of killing wild badgers to prevent tuberculosis in cattle is unlikely to succeed, according to a newstudy led by Rosie Woodroffe, an ecologist at the University ofCalifornia, Davis, and a member of Britain's Independent Scientific Group on Cattle TB.

A new gene linked to both depression and bipolar disorder has been identified by UCL (University College London) and Danish researchers.

The common antibiotic doxycycline effectively treats a type of lymphoma associated with chlamydia infection, according to a study in the October 4 issue of the Journal of the National Cancer Institute.

DNA's simple and elegant structure - the "twisted ladder," with sugar-phosphate chains making up the "rails" and oxygen- and nitrogen-containing chemical "rungs" tenuously uniting the two halves - seems to be the work of an accomplished sculptor.

Researchers from the University of Pennsylvania School of Veterinary Medicine have discovered a unique evolutionary link between the most primitive innate form of immune defense, which has survived in fish, to the more advanced, adaptive immune response present in humans and other mammals.

Physicists and medical researchers for the first time have demonstrated a new technique that non-invasively measures in real time the level of damage to the skin from sun exposure and aging, and initial results suggest that women's skin ages faster than men's. Findings appear in the October 1 issue of Optics Letters, a journal of the Optical Society of America.

The first real-data study of sharks harvested for their valuable fins estimates as few as 26 million and as many as 73 million sharks are killed each year worldwide--three times higher than was reported originally by the United Nations, according to a paper published as the cover story in the October 2006 edition of Ecology Letters.

New moorings are deployed from aboard the "Maria S. Merian" in the Fram-Strait. Several days ago, the 'Maria S Merian' returned from her second Arctic expedition with data confirming trends of Arctic warming.

A long-term vision of Pleistocene Rewilding -- a massive Ecological History Park of North America with free-roaming elephants, lions and other large animals that went extinct 13,000 years ago. Dozens of megafauna (large animals over 100 pounds) – such as giant tortoises, horses, elephants, and cheetah – went extinct in North America 13,000 years ago during the end of the Pleistocene. As is the case today in Africa and Asia, these megafauna likely played keystone ecological roles via predation, herbivory, and other processes. What are the consequences of losing such important components of America's natural heritage?
