Each time a human cell divides, it must first make a copy of its 46 chromosomes to serve as an instruction manual for the new cell. Normally, this process goes off without a hitch. But from time to time, the information isn't copied and collated properly, leaving gaps or breaks that the cell has to carefully combine back together. Researchers have long recognized that some regions of the chromosome,called "fragile sites," are more prone to breakage and can be a breeding ground for human...

Recent research has shown that tiny fragments of DNA circulating in a person's blood can allow scientists to monitor cancer growth and even get a sneak peek into a developing fetus' gene sequences. But isolating and sequencing these bits of genetic material renders little insight into how that DNA is used to generate the dizzying array of cells, tissues and biological processes that define our bodies and our lives. Now researchers at Stanford University have moved beyond relying on the...

Enzyme's double-edged sword may soon be sheathed Johns Hopkins biochemists have figured out what is needed to activate and sustain the virus-fighting activity of an enzyme found in CD4+ T cells, the human immune cells infected by HIV. The discovery could launch a more effective strategy for preventing the spread of HIV in the body with drugs targeting this enzyme, they say. A summary of their work was published online on April 21 in the journal Proceedings of the National Academy of...

Brett Smith for redOrbit.com - Your Universe Online While previous genetic research efforts have been able to identify a person’s ancestral origins within around 430 miles, a new system devised at the University of Sheffield in the United Kingdom can zero in on a person’s origin down to a particular village or island. According to a new report in the journal Nature Communications, the Sheffield researchers were able to develop a system called Geographic Population Structure (GPS)...

A next-generation genome editing system developed by Massachusetts General Hospital (MGH) investigators substantially decreases the risk of producing unwanted, off-target gene mutations. In a paper receiving online publication in Nature Biotechnology, the researchers report a new CRISPR-based RNA-guided nuclease technology that uses two guide RNAs, significantly reducing the chance of cutting through DNA strands at mismatched sites. "This system combines the ease of use of the widely...

Large sections of the genome that were once referred to as “junk” DNA have been linked to human heart failure, according to research from Washington University School of Medicine in St. Louis. So-called junk DNA was long thought to have no important role in heredity or disease because it doesn’t code for proteins. But emerging research in recent years has revealed that many of these sections of the genome produce RNA molecules that, despite not being proteins, still have important...

Scientists discover that modifications to the RNA of the powerhouses in each of your body's countless cells might be influencing your fitness Although our chromosomes are relatively stable within our lifetimes, the genetic material found in our mitochondria is highly variable across individuals and may impact upon human health, say researchers at the University of Montreal and its affiliated CHU Sainte-Justine Hospital. Genomes are changing, not just from generation to generation, but even...

Just a few grams of the new substance are enough to tag the entire olive oil production of Italy. If counterfeiting were suspected, the particles added at the place of origin could be extracted from the oil and analysed, enabling a definitive identification of the producer. "The method is equivalent to a label that cannot be removed," says Robert Grass, lecturer in the Department of Chemistry and Applied Biosciences at ETH Zurich. The worldwide need for anti-counterfeiting labels for food...

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...

Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
