Jefferson scientists explain cancer cell metabolism changes
Scientists at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia have found how a gene can dim the power production in the cell and in turn scale up its cancer-producing activities. view more (2006-08-29)
Newly found DNA catalysts cleave DNA with water molecule
Better tools for manipulating DNA in the laboratory may soon be possible with newly discovered deoxyribozymes (catalytic DNA) capable of cleaving single-stranded DNA, researchers at the University of Illinois say. view more (2009-08-17)
Enzyme necessary for DNA synthesis can also erase DNA
In this week's edition of Proceedings of the National Academy of Sciences, PNAS, Uppsala University scientists describe a new mechanism behind an important process that causes a rapid reduction of DNA in the chromosomes of bacteria. view more (2009-06-09)
DNA constraints control structure of attached macromolecules
A new method for manipulating macromolecules has been developed by researchers at the University of Illinois at Urbana-Champaign. The technique uses double-stranded DNA to direct the behavior of other molecules. view more (2005-06-29)
Have The Police Hijacked Our DNA? (p 927)
Creating a DNA database of all UK men to assist in criminal investigations may sound extreme; however this week's editorial proposes that there has been no more rational option to date in an attempt to use DNA profiling to assist in the identification of violent offenders in the UK, 80% of whom are men. The over-reliance by police and governments... view more... (2003-09-17)
Naturally fluorescent molecules may serve as cancer biomarker
Excess amounts of a naturally fluorescent molecule found in all living cells could serve as a natural biomarker for cancer, according to bioengineers. view more (2009-04-03)
DNA: Bacteria's survival ration
The ubiquitous bacteria E. coli rank among nature's most successful species for lots of reasons, to which biologists at the University of Southern California have added another: in a pinch, E. coli can feast on the DNA of their dead competitors. view more (2006-05-30)
Clues to future evolution of HIV come from African green monkeys
Monkey viruses related to HIV may have swept across Africa more recently than previously thought, according to new research from The University of Arizona in Tucson. view more (2007-07-17)
Yeast gives rise to new concept: cell fuel is 'brains' behind division
With the cost of diesel and gasoline getting nearer to the hourly minimum wage, too bad the fuel doesn't do more work - like deciding what route to take and pressing the gas pedal. view more (2008-04-28)
Adenine 'tails' make tailored anchors for DNA
Researchers from the National Institute of Standards and Technology (NIST), the Naval Research Laboratory (NRL) and the University of Maryland (UMD) have demonstrated a deceptively simple technique for chemically bonding single strands of DNA to gold. view more (2006-12-27)
A better test to detect DNA for diagnosing diease, investigating crimes
Researchers in Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA. view more (2009-08-27)
Old World Origin of New World Dogs
When humans arrived to the New World they had dogs with them. This is the conclusion reached by a study published this week in the journal Science by evolutionary biologists at the University of California, Los Angeles, and Uppsala University, Sweden, in collaboration with zooarchaeologists from Mexico and Peru. Dogs have been present in the New... view more... (2002-11-22)
Wired DNA
The hereditary DNA molecule was developed by nature to store the genetic information of its creatures. However in recent years it has been shown that this giant molecule could also have other qualities - it may also conduct electrical current. Three research groups that are looking into this subject have now published their results in Angewandte... view more... (1999-03-23)
Preserved in crystal
Scientists at the Weizmann Institute of Science recently discovered a new source of well-preserved ancient DNA in fossil bones. view more (2006-02-03)
A new light on the anti-tumor mechanisms of Scutellaria barbata
Medicinal plants have been used as traditional remedies for hundreds of years. Among them, S. barbata has been traditionally used in treatment of hepatitis, inflammation, osteomyelitis and gynecological diseases in China. view more (2009-01-05)
Toward more effective paleolgenetic analysis
DNA preserved in bones undergoing fossilization deteriorates up to 50 times faster when stored in a museum than when the bones are buried in the ground. view more (2007-01-18)
Agent orange chemical, dioxin, attacks the mitochondria to cause cancer, says Penn research team
Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression. view more (2007-12-18)
Tattooing improves response to DNA vaccine
A tattoo can be more than just a fashion statement - it has potential medical value, according to an article published in the online open access journal, Genetic Vaccines and Therapy. view more (2008-02-07)
Single-stranded DNA-binding protein is dynamic, critical to DNA repair
Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth along single-stranded DNA, gradually allowing other proteins to repair, recombine or replicate the strands. view more (2009-10-22)
University of Strathclyde DNA researcher wins Royal Society of Chemistry Award
A DNA researcher at the University of Strathclyde has been awarded over £200,000 by the Royal Society of Chemistry. Dr Duncan Graham has won the prestigious Analytical Grand Prix Fellowship in recognition of his groundbreaking research into DNA diagnostics. Dr Graham`s winning entry involves a new technique, SERRS* technology, which is... view more... (2002-09-04)
