Virus Reveals Physics Of Nanopores
2014-06-17 03:36:51

By Kevin Stacey, Brown University Nanopores may one day lead a revolution in DNA sequencing. By sliding DNA molecules one at a time through tiny holes in a thin membrane, it may be possible to decode long stretches of DNA at lightning speeds. Scientists, however, haven’t quite figured out the physics of how polymer strands like DNA interact with nanopores. Now, with the help of a particular type of virus, researchers from Brown University have shed new light on this nanoscale physics....

European Association of Geochemistry The subseafloor is home to over 1/3 of the bacteria on the planet, but up until recently it was unclear if this huge microbial biosphere was alive and dividing. Now the same group that demonstrated this activity has shown that bacteria from the hostile sea-floor environment have adapted by over-activating stress response and DNA-repair mechanisms, to cope with the harsh conditions. Subseafloor sediment contains the Earth's largest habitat for...

University of North Carolina Health Care The discovery, from the lab of Brian Strahl, Ph.D., offers insights for the creation of better, more targeted therapies for various forms of cancer Twelve years ago, UNC School of Medicine researcher Brian Strahl, PhD, found that a protein called Set2 plays a role in how yeast genes are expressed – specifically how DNA gets transcribed into messenger RNA. Now his lab has found that Set2 is also a major player in DNA repair, a complicated and...

University of Utah University of Utah researchers find that multiple silent mutations greatly impact protein translation So-called silent DNA mutations earned their title because, according to the fundamental rules of biology, they should be inconsequential. Reported on June 5 in PLOS Genetics online, University of Utah researchers experimentally proved there are frequent exceptions to the rule. The work was conducted in the bacteria, Salmonella enterica, used to study basic biological...

Researchers Create Initial Catalog Of Human Proteins
2014-05-30 03:12:06

Johns Hopkins Medicine Important resource for speeding research and diagnostic development Striving for the protein equivalent of the Human Genome Project, an international team of researchers has created an initial catalog of the human "proteome," or all of the proteins in the human body. In total, using 30 different human tissues, the team identified proteins encoded by 17,294 genes, which is about 84 percent of all of the genes in the human genome predicted to encode proteins. In...

Emory Health Sciences DNA methylation critical in model of atherosclerosis Disturbed patterns of blood flow induce lasting epigenetic changes to genes in the cells that line blood vessels, and those changes contribute to atherosclerosis, researchers have found. The findings suggest why the protective effects of good blood flow patterns, which aerobic exercise promotes, can persist over time. An epigenetic change to DNA is a chemical modification that alters whether nearby genes are...

Brief Introduction To DNA Probes
2014-01-12 00:00:00

DNA probes help scientists to detect a specific gene in a long DNA sequence. According to Dr. Michael A. Pfaller, DNA probes are “single-stranded pieces of nucleic acid, labeled with a specific tracer (isotope, enzyme, or chromophore), that will hydrogen bond (hybridize) with complementary single-stranded pieces of DNA (or RNA) under the appropriate conditions of pH, temperature, and iconic strength.” The Foundation for Genomics and Population Health website has a helpful video about...

Bacillus subtilis, also known as hay bacillus or grass bacillus, is a Gram-positive, catalase-positive bacterium commonly found in soil. It is rod-shaped and a member of the genus Bacillus. It also has the ability to form a tough, protective endospore, allowing the organism to tolerate extreme environmental conditions. B. subtilis has historically been classified as an obligate aerobe, though recent research has proven this to not be strictly correct. It is not a human pathogen although...
