Sexy Worms, an E-Tongue, and Kita Running [Sciencebase Science Blog] Posted: 14 Aug 2008 07:00 AM CDT Here is a sneak preview of the various science news items I have scheduled to appear on August 15 over on SpectroscopyNOW.com Stay young and beautiful - NMR spectroscopy has been used uncovered the secret of eternal youth and the ability to attract sexual partners almost at whim. The results suggest it all hinges on a novel group of pheromones. Unfortunately, before you head for the local pharmacy to stock up, these are pheromones of the lab-technician’s favourite worm, the nematode Caenorhabditis elegans, so they are likely to have no effect whatsoever on human behaviour or longevity. Electronic wine tasting - The wine buff’s palate is a complicated multisensory organ as anyone who knows their Bordeaux from their Beaujolais knows. Now, researchers have taken a step towards an artificial nose based on a system amenable to multivariate analysis. The system integrates a multisensor to test wine and grape juice samples for adulteration or vintage fraud. The Kita runners - Protein folding is one of the great conundrums of the twenty-first century. How exactly does a linear string of amino acids “know” into what three-dimensional cross-linked structure to fold itself? Moreover, how might molecular biologists predict this folding from first principles and how might the misfolding seen in prionic diseases, Alzheimer’s and other disorders be prevented or even reversed? A new clue about the folding of proteins comes from studies with a novel technique known as kinetic terahertz absorption spectroscopy (KITA). Green and peasant landscape - There’s also a bonus item on science in art. Post-impressionist artist was rich beyond his wildest dreams but only posthumously. He may have chopped off part of one ear, but he had double vision. At least that’s the idea that emerges from new X-ray studies of one his more mundane paintings - Patch of Grass - which reveals a portrait of a peasant woman beneath. a Sexy Worms, an E-Tongue, and Kita Running
