Despite their unassuming appearance, the planarian flatworms in Whitehead Institute Member Peter Reddien's lab are revealing powerful new insights into the biology of stem cells—insights that may eventually help such cells deliver on a promising role in regenerative medicine. http://phys.org/news249843008.html Biology Thu, 01 Mar 2012 16:53:32 EST news249843008 Timing is everything, and if there was ever a scientist whose legacy was tarnished by bad timing, it was Jean Baptiste Lamarck. The French naturalist lived from 1744 to 1829 - and published his own evolutionary theory decades before Darwin's theory went public in 1859. http://phys.org/news247822406.html Biology Tue, 07 Feb 2012 07:50:01 EST news247822406 Researchers at the University of California, San Francisco and the Stowers Institute for Medical Research have discovered that planarians, tiny flatworms fabled for their regenerative powers, completely lack centrosomes, cellular structures that organize the network of microtubules that pulls chromosomes apart during cell division. http://phys.org/news244986059.html Biology Thu, 05 Jan 2012 14:00:08 EST news244986059 A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report. http://phys.org/news206124658.html Biology Tue, 12 Oct 2010 18:20:01 EST news206124658 Two international research teams have determined the complete genetic sequences of two species of parasitic flatworms that cause schistosomiasis, a debilitating condition also known as snail fever. Schistosoma mansoni and Schistosoma japonicum are the first sequenced genomes of any organism in the large group called Lophotrochozoa, which includes other free-living and parasitic flatworms as well as segmented roundworms, such as the earthworm. http://phys.org/news166883423.html Biology Wed, 15 Jul 2009 13:32:14 EST news166883423
