Upside-down world: DNA protecting protein helps cancer drug to kill cells
Some DNA repair enzymes can become double-edged swords - If they work too slowly, they can block necessary cell maintenance and contribute to cell death. view more (2009-04-28)
Scientists reveal DNA-enzyme interaction with first ever real time footage
For the first time scientists have been able to film, in real-time, the nanoscale interaction of an enzyme and a DNA strand from an attacking virus. view more (2007-09-18)
Researchers find epigenetic signals differ across alleles
Researchers from the Institute of Psychiatry (IoP), King's College London, have identified numerous novel regions of the genome where the chemical modifications involved in controlling gene expression are influenced by either genetic variation or the parental origin of that particular stretch of DNA. view more (2010-02-16)
Genome advances peril for pests
Parasitic wasps kill pest insects, but their existence has been largely overlooked by the public - until now. view more (2010-01-15)
Draft version of the Neanderthal genome completed
The Max Planck Institute for Evolutionary Anthropology, in Leipzig, Germany, and the 454 Life Sciences Corporation, in Branford, Connecticut, will announce on 12 February during the 2009 Annual Meeting of the American Association for the Advancement of Science (AAAS) and at a simultaneous European press briefing that they have completed a first... view more...

New technique for cancer screening
Current research suggests that a new technique to determine tumor methylation status can be used in archived tissue samples. view more (2009-02-24)
DNA test shows promise for identifying patients with colorectal cancer (p 1283)
Testing for DNA changes in stools might provide a new, accurate, and less invasive way to screen patients for colorectal cancer, conclude the authors of a research letter in this week's issue of THE LANCET. Colorectal cancer is one of the most common cancers in the industrialised world, and early detection might help to reduce the risk of death... view more... (2004-04-14)
Foxes get frisky in the far north
Bees do it, chimps do it- Now it seems Arctic foxes do it, too. New research looking at the DNA fingerprints of canids in the Far North has revealed that foxes once thought to be monogamous are in fact quite frisky. view more (2007-07-18)
DNA size a crucial factor in genetic mutations, study finds
Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA. view more (2005-10-27)
Evolutionary conservation of a mechanism of longevity from worms to mammals
Though the study of aging in the nematode model organism C. elegans has provided much insight into this complex process, it is not yet clear whether genes involved in aging in the worm have a similar role in mammals. view more (2005-10-05)
Boston University reseachers develop faster, cheaper DNA sequencing method
Boston University biomedical engineers have devised a method for making future genome sequencing faster and cheaper by dramatically reducing the amount of DNA required, thus eliminating the expensive, time-consuming and error-prone step of DNA amplification. view more (2009-12-21)
Mescal 'worm' test shows DNA leaks into preservatives
Just because you don't swallow the worm at the bottom of a bottle of mescal doesn't mean you have avoided the essential worminess of the potent Mexican liquor, according to scientists at the University of Guelph. view more (2010-02-10)
A potential approach to treatment of hepatitis B virus infection
Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA. view more (2008-09-10)
Hippo ancestry disputed
Hippos spend lots of time in the water and now it turns out (or researchers argue), they are the closest living relative to whales. It also turns out, the two are swimming in a bit of controversy. view more (2009-03-19)
Crime scene or nature reserve?
A method used by forensic experts to collect evidence from crime scenes could soon be taken up by biologists studying animals in the wild. An article in BMC Ecology this week describes how DNA from animal blood and tissue samples can be stored on record cards made from specialist filter paper and used in experiments at a later date.... view more...

Chromatin remodeling complex connected to DNA damage control
When molecular disaster strikes, causing structural damage to DNA, players in two important pathways talk to each other to help contain the wreckage, scientists at The University of Texas M. D. Anderson Cancer Center report in the August edition of Cell. view more (2007-08-10)
'Pinball protons' created by ultraviolet rays and other causes can lead to DNA damage
Researchers have known for years that damaged DNA can lead to human diseases such as cancer, but how damage occurs-and what causes it-has remained less clear. view more (2006-05-18)
Chromosome glue repairs damaged DNA
When a strand of DNA breaks in the body's cells, it normally does not take long until it has been repaired. Now researchers at the Swedish medical university Karolinska Institutet have discovered a new mechanism that helps to explain how the cell performs these repairs. The results are presented in Science. view more (2007-07-16)
Changes to DNA linked to diabetes
Genes that regulate the energy consumption of cells have a different structure and expression in type II diabetics than they do in healthy people, according to a new study from the Swedish medical university Karolinska Institutet published in Cell Metabolism. view more (2009-09-02)
Precision biochemistry tracks DNA damage in fish
Like coal-mine canaries, fish DNA can serve as a measure of the biological impact of water and sediment pollution-or pollution clean-up. view more (2006-05-15)
