Development of a new way to make a powerful tool for altering gene sequences should greatly increase the ability of researchers to knock out or otherwise alter the expression of any gene they are studying. The new method allows investigators to quickly create a large number of TALENs (transcription activator-like effector nucleases), enzymes that target specific DNA sequences and have several advantages over zinc-finger nucleases (ZFNs), which have become a critical tool for investigating...

Discovery may create dialogue about DNA and RNA data bank privacy issues Researchers from Mount Sinai School of Medicine have developed a method to derive enough DNA information from non-DNA sources–such as RNA–to clearly identify individuals whose biological data are stored in massive research repositories. The approach may raise questions regarding the ability to protect individual identity when high-dimensional data are collected for research purposes. A paper introducing...

Researchers at UCLA and New York University have developed a method to detect sequence differences in individual DNA molecules by taking nanoscopic pictures of the molecules themselves. The work is reported in the Journal of the Royal Society Interface. Using the approach they call "Direct Molecular Recognition," the UCLA and NYU researchers used nanoparticles to turn the DNA molecules into a form of molecular braille that can be read in the scale of nanometers, or one billionth of a...

Remember Slinky®, the coiled metal spring that "walks" down stairs with just a push, momentum and gravity? Researchers at the National Institute of Standards and Technology (NIST) have developed their own version of this classic–albeit 10 million times smaller–as a novel technology for manipulating and measuring DNA molecules and other nanoscale (billionth of a meter) materials. In the first of two recent papers, Samuel Stavis, Elizabeth Strychalski and colleagues...

Using state-of-the-art technology, scientists at the Novo Nordisk Foundation Center for Protein Research at the University of Copenhagen and their international collaborators have successfully obtained "molecular snapshots" of tens of thousands processes involved in DNA damage repair. On a daily basis this restoration keeps cells healthy and prevents the development of cancer. The results of this study will help unravel exactly how cells repair their broken DNA, how chemotherapy affects...

So what is it that gives NY Knicks Jeremy Lin his unique competitive edge? Greg Herzog, a former sub four minute miler and conditioning specialist in New York City has worked with competitive athletes, as well as individuals from the ages 5-94, and has made studying human performance his life´s work. This extensive experience led to the development of “AXIS CORE®”, a mathematical equation to predict and change behavior, as well as a Quantum Reaction Theory: COLOR CODING...

The search for a solid answer on whether DNA can be reprogrammed or influenced through frequencies and words may have been answered based on a recent study by noted Russian biophysicist and molecular biologist Pjotr Garjajev and supporting article posted at BeWellBuzz.com. Las Vegas, NV (PRWEB) February 23, 2012 The search for a solid answer on whether DNA can be reprogrammed or influenced through frequencies and words may have been answered based on a recent study by noted Russian...

Molecule is important step along the path to someday creating drugs that can go after rogue DNA directly Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported. It's an important step along the path to someday creating drugs that can go after rogue DNA directly. Such drugs would...

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...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
