Polynesian Chickens May Have Flown The Coop, But They Didn't Make It To South America: Study
2014-03-19 11:07:14

Lawrence LeBlond for redOrbit.com - Your Universe Online It is commonly agreed in the scientific community that Polynesians expanded their culture throughout the South Pacific some 3,000 years ago and later arrived in places like Tahiti and Hawaii. But did the Polynesians make it all the way to South America? And if they did, did they beat Columbus? New evidence paints a pretty clear picture that Polynesians were in fact not the first to arrive in South America, and maybe never made the...

Delivery Of Genomic Building Blocks Controlled By Enzyme
2014-03-07 10:14:25

University of Copenhagen Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how an enzyme controls reliable and high-speed delivery of histones to DNA copying hubs in our cells. This shuttling mechanism is crucial to maintain normal function of our genes and prevent disease. The results are published in the journal Nature...

Fragile X Syndrome
2014-02-28 13:24:30

Brett Smith for redOrbit.com - Your Universe Online New research from a team of American researchers has found a genetic mechanism that shuts off the gene associated with fragile X syndrome – which causes developmental disorders such as mental retardation and autism. According to the team’s report in the journal Science, they were successfully able to a test drug that blocks this blocking mechanism. While it has been known that the syndrome is driven by the excessive repetition...

As the price for decoding a person's DNA keeps dropping, expectations for personalized medicine based on specific genetic profiling rise. But translating an individual's genetic data into finely tailored medical treatments still faces major challenges, explains a new article in Chemical & Engineering News (C&EN), the weekly magazine of the American Chemical Society. Rick Mullin, senior editor at C&EN, notes that advances in DNA sequencing have allowed researchers to design some...

How Well Did You Sequence That Genome?
2014-02-27 13:24:50

National Institute of Standards and Technology (NIST) In December 2013, the U.S. Food and Drug Administration approved the first high-throughput DNA sequencer (also known commonly as a "gene sequencer"), an instrument that allows laboratories to quickly and efficiently sequence a person's DNA for genetic testing, medical diagnoses and perhaps one day, customized drug therapies. Helping get the new device approved was another first: the initial use of a reference set of standard genotypes,...

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...
