UW scientists unravel critical genetic puzzle for flu virus replication
Like any other organism, an influenza virus's success in life is measured by its genetic track record, its ability to pass on genes from one generation to the next. view more (2006-01-26)
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)
Barcoding endangered sea turtles
Conservation geneticists who study sea turtles have a new tool to help track this highly migratory and endangered group of marine animals: DNA barcodes. view more (2009-09-15)
Chaos, Twist Maps and Big Business
Obscure mathematical ideas developed back in the 1980s could solve current problems of mixing fluids at the microscale, and revolutionise the technology, reports an article in Science this week (23 July 2004). The need to mix fluids at the microscale affects a whole range of developing technologies - from inkjet printers to DNA analysis - and... view more... (2004-07-23)
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)
University of Iowa scientists explore function of 'junk DNA'
University of Iowa scientists have made a discovery that broadens understanding of a rapidly developing area of biology known as functional genomics and sheds more light on the mysterious, so-called "junk DNA" that makes up the majority of the human genome. view more (2006-11-14)
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)
Scientists unlock clues for tailoring corn plant for food, energy needs
Scientists have long known that the offspring of two inbred strains tend to be superior to both their parents. Now, a team of researchers including a University of Florida geneticist has discovered clues to why that might be the case for one of the most important crops in the world: corn. view more (2009-11-20)
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)
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)
Mobile DNA part of evolution's toolbox
The repeated copying of a small segment of DNA in the genome of a primeval fish may have been crucial to the transition of ancient animals from sea to land, or to later key evolutionary changes in land vertebrates. view more (2006-05-03)
Tiny differences in our genes help shed light on the big picture of human history
By examining very small differences in people's genes, scientists from Cornell University have developed a new tool for identifying big events in human history and pinpointing the origins of specific gene mutations. view more (2009-04-30)
Under magnetic force, nanoparticles may deliver gene therapy
After binding DNA segments to tiny iron-containing spheres called nanoparticles, researchers have used magnetic fields to direct the nanoparticles into arterial muscle cells, where the DNA could have a therapeutic effect. view more (2007-08-01)
Scientists create custom 3-dimensional structures with 'DNA origami'
By combining the art of origami with nanotechnology, Dana-Farber Cancer Institute researchers have folded sheets of DNA into multilayered objects with dimensions thousands of times smaller than the thickness of a human hair. view more (2009-05-21)
Key brain regulatory gene shows evolution in humans
Researchers have discovered the first brain regulatory gene that shows clear evidence of evolution from lower primates to humans. view more (2005-12-13)
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)
