FINDINGS: Several structurally similar small molecules appear capable of protecting cells from alpha-synuclein toxicity, a hallmark of Parkinson's disease. RELEVANCE: Parkinson's disease is a neurodegenerative disorder characterized by tremors, muscle rigidity, and slowed movements. There is currently no cure for the disease, and current Parkinson's therapies only address disease symptoms, not the disease's cellular cause. Small molecules found to protect cells in multiple models of...

Mold and mildew may be doomed. Researchers are closer to understanding how these and other fungi grow. "Fungi have a big impact on our dinner plate," said Dr. Brian Shaw, Texas AgriLife Research plant pathologist. "We tend to think that getting food on the table is easy. But fungi are major disease-causing organisms for both plants and animals. With more research, we can find new ways to compete with them." Commonly known fungi are molds, mildews, mushrooms and yeast. Anyone who thinks humans...

With the introduction of a single bacterial gene into yeast, researchers from Delft University of Technology in the Netherlands achieved three improvements in bioethanol production from agricultural waste material: 'More ethanol, less acetate and elimination of the major by-product glycerol' This week the invention was published in the scientific journal Applied and Environmental Microbiology. Car fuel Bioethanol is made by the yeast Saccharomyces cerevisiae from sugars obtained from plant...

As global temperatures and energy costs continue to soar, renewable sources of energy will be key to a sustainable future. An attractive replacement for gasoline is biofuel, and in two studies published online in Genome Research (www.genome.org), scientists have analyzed the genome structures of bioethanol-producing microorganisms, uncovering genetic clues that will be critical in developing new technologies needed to implement production on a global scale. Bioethanol is produced from the...

Discovery Has Potential to Make Renewable Fuel Production More Efficient and Economical A team of researchers led by University of California, Riverside (UCR) Professor of Chemical Engineering Wilfred Chen has constructed for the first time a synthetic cellulosome in yeast, which is much more ethanol-tolerant than the bacteria in which these structures are normally found. The yeast cellulosome could enable efficient one-step "consolidated bioprocessing" by maximizing the catalytic efficiency...

Kraft Foods, four days after announcing a name for a new variety of the Australian spread Vegemite, announced Australians don't like iSnack2.0. The problem is not the product, a creamier version of the yeast-based spread, The Australian reported. The problem is the name, selected from among 48,000 suggestions from the public. Simon Talbot, the company's top spokesman in Australia, said iSnack.2.0 will continue to appear on store shelves for several months. In the meantime, Kraft plans to hold...

Until now, the mode of action of nitrogen-containing bisphosphonate (N-BP) cancer drugs, used to relieve bone pain and to prevent skeletal complications in bone metastasis, has been almost entirely unknown. Researchers writing in BioMed Central's open access journal Genome Biology have used 'barcoded' yeast mutants to identify new biological processes involved in the cellular response to N-BPs, opening up opportunities for the development of new anticancer drugs. Daniela Delneri, from the...

Turning grape juice into wine is a stressful business for yeasts. Dr Agustin Aranda from the University of Valencia, Spain has identified the genes in yeast that enable it to respond to stress and is investigating ways to improve yeast performance by modifying its stress response mechanism. Speaking at the Society for General Microbiology meeting at Heriot-Watt University, Edinburgh, today (9 September), Dr Aranda described the stresses that wine yeasts undergo in the fermentation process....

On Friday, controversial biologist Dr Craig Venter said that the creation of artificial life was mere months from taking place. Venter reported that his team of researchers at the J Craig Venter Institute in Maryland had transferred the DNA of one type of bacteria into a yeast cell before modifying it and transferring in into another cell, according to the Daily Mail. Researchers said the new method allowed them to clone the entire bacterial genome from Mycoplasma mycoides by adding yeast...

Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois.When ethanol is produced, distiller's dried grain with solubles (DDGS) is a waste product. The DDGS is primarily used as animal feed, but researchers are searching for ways to extract the sugar and ferment it to produce an...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
