Designer molecule detects tiny amounts of cyanide, then glows http://newsinfo.iu.edu/news/page/normal/12286.html Wed, 21 Oct 2009 02:25:00 EST A small molecule designed to detect cyanide in water samples works quickly, is easy to use, and glows under ultraviolet or "black" light. Although the fluorescent molecule is not yet ready for market, its Indiana University Bloomington creators report in the Journal of the American Chemical Society (now online) that the tool is already able to sense cyanide below the toxicity threshold established by the World Health Organization.

New science department at IU Bloomington links biology, chemistry, and medical sciences http://newsinfo.iu.edu/news/page/normal/11680.html Mon, 24 Aug 2009 09:51:00 EST The new Department of Molecular and Cellular Biochemistry is the first science department created on the Indiana University Bloomington campus in 33 years, and is the culmination of more than seven years of planning. The IU Trustees recently approved the department. The department is offering M.S. and Ph.D. degrees in biochemistry, but does not award undergraduate degrees. Biochemistry faculty members will teach undergraduate courses, however, for their departmental allies, Biology and Chemistry.

Speciation through genome duplication more common in plant evolution than previously thought http://newsinfo.iu.edu/news/page/normal/11604.html Wed, 12 Aug 2009 09:35:00 EST Extra genomes appear, on average, to offer no benefit or disadvantage to plants, but still play a key role in the origin of new species, say scientists from Indiana University Bloomington and three other institutions in this week's Proceedings of the National Academy of Sciences. Plant biologists have long suspected polyploidy -- the heritable acquisition of extra chromosome sets -- was a gateway to speciation. But the consensus was that polyploidy is a minor force, a mere anomaly that accounts for 3 or 4 percent of the world's flowers and ferns.

After dinosaurs, mammals rise but their genomes get smaller http://newsinfo.iu.edu/news/page/normal/11467.html Mon, 27 Jul 2009 07:02:00 EST Evidence buried in the chromosomes of animals and plants strongly suggests only one group -- mammals -- have seen their genomes shrink after the dinosaurs' extinction. What's more, that trend continues today, say Indiana University Bloomington scientists in the first issue of a new journal, Genome Biology and Evolution.

Parasitic worms make sex worthwhile http://newsinfo.iu.edu/news/page/normal/11460.html Thu, 23 Jul 2009 12:11:00 EST The coevolutionary struggle between a New Zealand snail and its worm parasite makes sex advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, say Indiana University Bloomington and Swiss Federal Institute of Technology biologists in this week's Current Biology. The scientists' report represents direct experimental evidence for the "Red Queen Hypothesis" of sex, which suggests sexual reproduction allows host species to avoid infection by their coevolving parasites by producing genetically variable offspring.

The project, led by IU Bloomington structural biologist Joel Ybe, has focused on the interaction of two proteins, HIP1 (Huntingtin-interacting protein 1) and HIPPI (HIP1-protein interactor), whose association is believed to trigger the death of nervous system cells.

Bacterial biofilms as fossil makers http://newsinfo.iu.edu/news/page/normal/9350.html Tue, 25 Nov 2008 09:32:00 EST Bacterial decay was once viewed as fossilization's mortal enemy, but new research suggests bacterial biofilms may have actually helped preserve the fossil record's most vulnerable stuff -- animal embryos and soft tissues. A team of 13 scientists led by Indiana University Bloomington biologists Rudolf and Elizabeth Raff found that the invasion of dying embryo cells by bacteria -- and the subsequent formation of densely packed bacterial biofilms inside the embryo cells -- can completely replace embryo cell structure, generating a faithful replica of the embryo.
