Viruses Evolve To Play By Host Rules (3/4/2008)Biologists have examined the complete genomes of viruses that infect the bacteria E. coli, P. aeruginosa and L. lactis and have found that many of these viral genomes exhibit codon bias, the tendency to preferentially encode a protein with a particular spelling. ...> Full Article Scientists rebuild ancient proteins to reveal primordial Earth's temperature (2/11/2008)Using the genetic equivalent of an ancient thermometer, a team of scientists has determined that the Earth endured a massive cooling period between 500 million and 3.5 billion years ago. ...> Full Article Geneticist Uses New Computational Methods to Search for a Neanderthal Legacy and for Disease Genes (1/20/2008)
Human Genetic Variation: Science's 'Breakthrough Of The Year' (1/1/2008)In 2007, researchers were dazzled by the degree to which genomes differ from one human to another and began to understand the role of these variations in disease and personal traits. Science and its publisher, AAAS, the nonprofit science society, recognize "Human Genetic Variation" as the Breakthrough of the Year, and identify nine other of the year's most significant scientific accomplishments. ...> Full Article Study Maps Life in Extreme Environments, Creating Potential for Molecular Bioengineering and Dynamical Models of Cells (12/31/2007)
NIH Launches Human Microbiome Project, (12/25/2007)Roadmap Effort to Use Genomic Technologies To Explore Role of Microbes in Human Health and Disease ...> Full Article Researchers study viruses at deep-sea vents (12/24/2007)
Researchers Solve First Structure of a Key to Intact DNA Inheritance (12/23/2007)Researchers have solved the structure of a DNA-protein complex that is crucial in the spread of antibiotic resistance among bacteria. Knowing this structure also provides fundamental insight into how cells successfully divide into two new cells with intact DNA. ...> Full Article Team discovers bacterial surprise (12/7/2007)A DNA shift never before seen in nature ...> Full Article Flip-Flopping Gene Expression Can Be Advantageous (11/22/2007)
The bacteria can cheat on their mates (11/16/2007)Pursuing our own short term interests by cheating on the rest of the population is not the preserve of the human race. It seems bacteria can operate in just the same way. ...> Full Article Human Microbiome Projects to sequence 150 bacteria, sample human metagenome (11/4/2007)A $2.3 million grant from the National Human Genome Research Institute will enable researchers at the Baylor College of Medicine Human Genome Sequencing Center in Houston to determine the genetic code of bacteria that colonize healthy humans and study the structure of microbial communities from five regions of the human body. ...> Full Article Bacteria Use Plant Defence for Genetic Modification (10/23/2007)

Bacteria Mutate Much More Than Previously Thought (8/20/2007)
New Method Better Identifies Functionally Related Genes On The Bacterial Chromosome (8/1/2007)The moment a bacterial pathogen makes contact with its host, its goal is simple: to infect. To do the job, it has to turn a specific array of genes on and off and show a little know-how in adapting to its new environment. A new tool developed at Rockefeller University allows scientists to identify more precisely than before this specific array of genes - known and unknown - that are expressed as a result of this interaction as well as determine what functions they may perform. ...> Full Article Surprising New Species Of Light-harvesting Bacterium Discovered In Yellowstone (7/26/2007)In the hot springs of Yellowstone National Park, a team of researchers has discovered a novel bacterium that transforms light into chemical energy. The discovery of the chlorophyll-producing bacterium, Candidatus Chloracidobacterium (Cab.) thermophilum, will be described in the July 27 issue of the journal Science in a paper led by Don Bryant, Ernest C. Pollard professor of biotechnology in the Department of Biochemistry and Molecular Biology at Penn State, and David M. Ward, professor of microbial studies in the Thermal Biology Institute and Department of Land Resources and Environmental Sciences at Montana State University, and colleagues. ...> Full Article How Pathogens Evolve To Escape Detection (7/20/2007)
Parasite Supports Host By Becoming Fertility Aid (4/28/2007)Bacteria that commonly infect insects have evolved from parasites to being a fertility aid. The bacteria could eventually be targeted as an option for pest control in order to kill common human disease carriers such as mosquitoes. ...> Full Article |
