As part of an international research project, a team of researchers has developed a DNA clamp that can detect mutations at the DNA level with greater efficiency than methods currently in use. Their work could facilitate rapid screening of those diseases that have a genetic basis, such as cancer, and provide new tools for more advanced nanotechnology. The results of this research is published this month in the journal ACS Nano. Toward a new generation of screening tests An increasing...

Researchers have created a new type of molecular motor made of DNA and demonstrated its potential by using it to transport a nanoparticle along the length of a carbon nanotube. The design was inspired by natural biological motors that have evolved to perform specific tasks critical to the function of cells, said Jong Hyun Choi, a Purdue University assistant professor of mechanical engineering. Whereas biological motors are made of protein, researchers are trying to create synthetic...

Findings may be useful in design of future drugs and catalysts The theory of evolution suggests that present-day organisms evolved from earlier life forms. At the molecular level, evolution reshaped some of the enzymes that help complete chemical processes—such as converting food into energy—in humans and all other life forms. Now a University of Iowa researcher and his colleagues describe the evolution of various forms of the enzyme “dihydrofolate reductase” as it occurred...

University of California - Riverside Findings by UC Riverside researchers could help build a new drug to kill the deadly parasite that is becoming resistant to existing drugs Say "malaria" and most people think "mosquito," but the buzzing, biting insect is merely the messenger, delivering the Plasmodium parasites that sickened more than 200 million people globally in 2010 and killed about 660,000. Worse, the parasite is showing resistance to artemisinin, the most effective drug for...

New Online Database Sheds Light On Gene Patenting Process
2013-12-08 06:29:33

redOrbit Staff & Wire Reports – Your Universe Online Researchers from Cambria, a non-profit biotech research organization, and the Queensland University of Technology (QUT), have developed a new online database revealing which organizations have applied for patents related to genes and proteins in living organisms. The open-sourced PatSeq registry, which is the subject of a paper published in last week’s edition of Nature Biotechnology, currently holds over 120 million DNA...

[ Watch the Video: Will Beer Or Coffee Contribute To Your Aging? ] Alan McStravick for redOrbit.com - Your Universe Online Each time our cells replicate in our bodies, the end points of chromosomal DNA - known as telomeres - copy themselves to the new cell, shortening with each subsequent copy until they can no longer keep the cell viable, resulting in its eventual death. However, a group of researchers from Tel Aviv University’s (TAU) Department of Molecular Microbiology and...

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...
