Latest Yeast Stories
Scientists have overturned the conventional wisdom that cooperation is essential for the well-being of the whole population, finding evidence that slackers can sometimes help the common good. Researchers, from Imperial College London, the Universities of Bath and Oxford, University College London and the Max Planck Institute for Evolutionary Biology studied populations of yeast and found that a mixture of 'co-operators' and 'cheats' grew faster than a more utopian one of only...
SKILLMAN, N.J., Sept. 9 /PRNewswire/ -- For more information, please go to: http://monistat.presslift.com/yeastinfections. Few women go through life having never suffered from the uncomfortable symptoms of a yeast infection. In fact, nearly 3 in 4 (72 percent) women will experience their first yeast infection before age 25. (1) Furthermore, the incidence of yeast infections is highest among young women ages 18-24 (2), who are new to the category and uncertain about symptoms and available...
Two opportunistic pathogens that were once thought to be very different have evolved some sexual reproduction and disease-causing habits that are not only similar but also suggest that in the microbial world sex and virulence are closely linked, according to a review published this week in the online journal mBioâ„¢."Although the mechanisms used by bacterial and fungal species to promote genetic exchange are distinct, recent studies have uncovered surprising parallels between...
SEATTLE, June 11 /PRNewswire/ -- How is it that some people who apparently freeze to death, with no heart rate or respiration for extended periods, can be brought back to life with no long-term negative health consequences? New findings from the laboratory of cell biologist Mark B. Roth, Ph.D., of Fred Hutchinson Cancer Research Center, may help explain the mechanics behind this widely documented phenomenon. Reporting online ahead of the July 1 print issue of Molecular Biology of the Cell,...
Purdue University scientists have improved a strain of yeast that can produce more biofuel from cellulosic plant material by fermenting all five types of the plant's sugars.Nathan Mosier, an associate professor of agricultural and biological engineering; Miroslav Sedlak, a research assistant professor of agricultural and biological engineering; and Nancy Ho, a research professor of chemical engineering, used genes from a fungus to re-engineer a yeast strain Ho developed at Purdue. The new...
Scientists at the Department of Energy's Oak Ridge National Laboratory are improving strains of microorganisms used to convert cellulosic biomass into ethanol, including a recent modification that could improve the efficiency of the conversion process.Biofuels researchers and industrials have generated improved mutant microorganisms previously, but authors of a paper in the on-line Proceedings of the National Academy of Sciences identify a key Z. mobilis gene for the first time and show the...
A combination of enzymes and fermentation modifies bran structure and changes the bioavailability of the bioactive compound, according to new studies forming part of the European Union's large-scale HEALTHGRAIN project. Bioprocessing of bran has potential for making it a better ingredient for use in manufacturing nutritionally boosted cereal foods with high sensory quality.The health benefits of whole grain and grain dietary fibre are well documented, and dietary reecommendations worldwide...
Université de Montréal scientists uncover mystery in journal NatureA mystery about the mechanism behind sexual mate selection has been resolved. According to a new study published in the journal Nature, Université de Montréal researchers have discovered a molecular switch that becomes activated in response to a potential mate's signal. Simply put, an organism knows that a potential mate is close-by and healthy enough to mate."This mating decision is controlled by a simple...
Scientists devise way to link complex traits with underlying genesPrinceton University scientists have developed a new way to identify the hidden genetic material responsible for complex traits, a breakthrough they believe ultimately could lead to a deeper understanding of how multiple genes interact to produce everything from blue eyes to blood pressure problems.Writing in the April 15 edition of Nature, scientists led by Leonid Kruglyak, a professor in Princeton's Department of Ecology and...
Engineering yeast to transform sugars more efficiently into alcohols could be an economically and environmentally sound way to replace fossil fuels, say scientists presenting at the Society for General Microbiology's spring meeting in Edinburgh on Sunday. Dr Christian Weber and Professor Eckhard Boles from Frankfurt University, Germany, have worked out how to modify yeast cells so that they successfully convert a wider range of sugars from plant waste such as wheat and rice straw into alcohol...
