Leeches To Track Mammal DNA In Jungles
2012-04-24 06:10:55

Connie K. Ho for RedOrbit.com Researchers from Copenhagen Zoo and the University of Copenhagen have discovered a way to track mammals in the jungles of Southeast Asia. Scientists collected leeches from the jungles to analyze the blood and DNA of animals taken by the parasites. With this new method, researchers will be able to study the biodiversity of the mammals without having to track each one down. The findings, to be published in science journal Current Biology, allow scientists to...

This new T. rex has ferociously large teeth lining a single jaw. But its length is less than 2 inches. Tyrannobdella rex, which means tyrant leech king, is a new species of blood sucker that lives in the remote parts of the Upper Amazon. Although its regular host remains unknown, it was discovered three years ago in Perú when a 44.5 millimeter leech was plucked from the nose of a girl who had recently been bathing in a river. The new species, described in PLoS ONE, has led...

Researchers at the California Institute of Technology (Caltech) and the University of California, San Diego (UCSD) have discovered that injecting a simple hormone into leeches creates a novel way to study how hormones and the nervous system work together to produce species-specific reproductive behavior. A paper describing the work appears in the March 11 online edition of the journal Current Biology. Daniel Wagenaar, Broad Senior Research Fellow in Brain Circuitry at Caltech and first author...

As the use of leeches in a variety of medical therapies is beginning to increase in popularity, an institution in Russia is hoping to cash in. The International Medical Leech Center in Udelnaya refers to itself as the world's largest leech-growing facility. Many experts and leading institutions have begun approving the use of leeches for medical procedures. Earlier this year, the American Journal of Nursing confirmed a resurgence of leech therapy, primarily among patients who underwent...

Appearing in the Jan. 16, 2009, issue of JBCAs bacteria resistant to commonly used antibiotics continue to increase in number, scientists keep searching for new sources of drugs. In this week's JBC, one potential new bactericide has been found in the tiny freshwater animal Hydra.The protein identified by Joachim Grötzinger, Thomas Bosch and colleagues at the University of Kiel, hydramacin-1, is unusual (and also clinically valuable) as it shares virtually no similarity with any other...

Bethesda, MD "“ The leech has recently confirmed its biomedical interest for scientists by showing that it contains an extensive list of new potential molecules that may become useful tools in the treatment of cardiovascular diseases. The details of this research appear in the October issue of Molecular and Cellular Proteomics, an American Society for Biochemistry and Molecular Biology journal. Scientists have increasingly turned to blood-feeding invertebrates as a source for drugs and...
