UBC scientists find new way to extract diluted and contaminated DNA
University of British Columbia researchers have developed a new way to extract DNA and RNA from small or heavily contaminated samples that could help forensic investigators and molecular biologists get to "the truth." view more (2009-08-11)
Researchers Find Synthetic Molecules That May Literally Be The Key To “Locking Away” Unwanted DNA
Research chemists have a found a class of synthetic molecules that could quite literally act as a key which could lock away sections of DNA into a closely wound coil preventing proteins from interacting with particular sections of DNA code. By locking up the DNA in this way scientists could stop particular sequences of DNA from activating... view more... (2002-04-15)
Reduced mitochondrial function important mechanism in aging
Scientists at the Karolinska Institute have found that changes in the "powerhouse" of cells, the mitochondria, play a key role in aging. The findings are being published in this week's issue of the journal Nature. Mitochondria, which provide energy to cells, have their own set of DNA. Mutations of mitochondrial DNA increase with age,... view more... (2004-05-27)
After dinosaurs, mammals rise but their genomes get smaller
Evidence buried in the chromosomes of animals and plants strongly suggests only one group -- mammals -- have seen their genomes shrink after the dinosaurs' extinction. view more (2009-07-28)
Important new model shows how proteins find the right DNA sequences
Researchers at Uppsala University and Harvard University have collaboratively developed a new theoretical model to explain how proteins can rapidly find specific DNA sequences, even though there are many obstacles in the way on the chromosomes. view more (2009-03-16)
DNA differences may influence risk of Hodgkin disease
A new analysis has found that certain variations in genes that repair DNA can affect a person's risk of developing Hodgkin disease. view more (2009-03-09)
DNA’s oscillating double helix hinders electrical conduction
DNA has an oscillating double-helix structure. This oscillating means that the DNA molecules conduct electricity much less well than was previously thought. Ultrafast cameras were one of the devices the researchers from Amsterdam used to demonstrate this. It turns out the DNA does not have a rigid regular structure as stated in textbooks. In... view more... (2002-09-11)
Immune system response to viral DNA is unique
The human body has a unique immune system response to foreign DNA, suggesting that DNA viruses and RNA viruses are detected by different mechanisms. view more (2006-01-25)
New hope for deadly childhood bone cancer
Researchers at Huntsman Cancer Institute (HCI) at the University of Utah have shed new light on Ewing's sarcoma, an often deadly bone cancer that typically afflicts children and young adults. view more (2009-08-31)
Antitumor agent under the microscope
Mechanical stabilization of DNA keeps tumor cells in check Cisplatin is one of the most widely employed cancer medications. As with many other chemotherapy agents, the mechanism by which it works has not been fully researched. Now, thanks to Munich physicists Hermann E. Gaub, Rupert Krautbauer, and Hauke Clausen-Schaumann, an important step toward... view more... (2000-10-30)
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)
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)
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)
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)
50 years after Sputnik
In cosmic terms, half a century is a mere blink of an eyelid. But for mankind, much has happened in the 50 years since Sputnik 1, the first artificial satellite, was launched by the Soviet Union on 4 October 1957. view more (2007-10-03)
