LONG BEACH, Calif., Sept. 10 /PRNewswire/ -- "Why free? I want to level the playing field. The only variable in this system is you. All I ask in return for using my system is for every user to share it with as many people as they can," said Bob Ainuu Afamasaga. "Millions of Europeans are losing their jobs...we must also keep the cost of all these measures in mind because, as I have already said several times, creating debt is no solution..." said European Council President Mirek...

New York University chemists have created three-dimensional DNA structures, a breakthrough bridging the molecular world to the world where we live. The work, reported in the latest issue of the journal Nature, also has a range of potential industrial and pharmaceutical applications, such as the creation of nanoelectronic components and the organization of drug receptor targets to enable illumination of their 3D structures. While scientists, including those involved in this study, have...

In the chilling science fiction movie Gattaca, Ethan Hawke stars as a man with "inferior genes" who assumes another's genetic identity to escape a dead-end future. The 1997 film illustrates the very real fear swirling around today's genome research "” fear that private genetic information could be used negatively against us. Last year, after a published paper found serious security holes in the way DNA data is made publicly available, health institutes in the United States and across...

Scientists at the California Institute of Technology (Caltech) and IBM's Almaden Research Center have developed a new technique to orient and position self-assembled DNA shapes and patterns"”or "DNA origami""”on surfaces that are compatible with today's semiconductor manufacturing equipment. These precisely positioned DNA nanostructures, each no more than one one-thousandth the width of a human hair, can serve as scaffolds or miniature circuit boards for the precise assembly of...

Using tiny crystals called quantum dots, Johns Hopkins researchers have developed a highly sensitive test to look for DNA attachments that often are early warning signs of cancer. This test, which detects both the presence and the quantity of certain DNA changes, could alert people who are at risk of developing the disease and could tell doctors how well a particular cancer treatment is working.The new test was reported in a paper called "MS-qFRET: a quantum dot-based method for analysis of...

A new discovery may make it easier for scientists to manipulate DNA in the laboratory, a paper from the University of Illinois at Urbana Champagne said. Three scientists at the university discovered catalytic DNA known as deoxyribozymes that can cleave DNA strands to become catalysts for research. The scientists, chemistry Professor Scott Silverman, postdoctoral research associate Madhavaiah Chandra and graduate student Amit Sachdeva were searching for artificial sequences of DNA to cleave...

EMBL scientists identify a rapid response team that monitors and quickly responds to DNA damageOur genome is constantly under attack from things like UV light and toxins, which can damage or even break DNA strands and ultimately lead to cancer and other diseases. Scientists have known for a long time that when DNA is damaged, a key enzyme sets off a cellular "Ëœalarm bell' to alert the cell to start the repair process, but until recently little was known about how the cell detects...

Scientists at the Technische Universitaet Muenchen (TUM) and Harvard University have thrown the lid off a new toolbox for building nanoscale structures out of DNA, with complex twisting and curving shapes. In the August 7 issue of the journal Science, they report a series of experiments in which they folded DNA, origami-like, into three dimensional objects including a beachball-shaped wireframe capsule just 50 nanometers in diameter."Our goal was to find out whether we could program DNA to...

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...
