Milestone tumor virus publication by Elsevier journal Virology
A recent special edition of the Elsevier journal Virology reviews the past, present, and future of the exciting field of small DNA tumor viruses. view more (2009-04-10)
Researchers gain insight into mechanism underlying Huntington's
Researchers at the University of Kentucky Markey Cancer Center and Graduate Center for Toxicology (GCT) have gained new insight into the genetic mechanisms underlying Huntington's disease and other neurodegenerative or neuromuscular disorders caused by trinucleotide repeats (or TNRs) in DNA. view more (2009-07-14)
When Good DNA Goes Bad: Backward DNA leads to DNA breaks associated with leukemia, study finds
When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma. view more (2006-02-13)
Gene for neat repair of DNA discovered
Researchers from the Erasmus University in Rotterdam have demonstrated that a gene helps in the neat repair of DNA. Without this gene the body would repair damaged DNA in a careless manner more often. This causes new damage, which can lead to cancer. The careless repair of damaged DNA can cause mutations and can result in cancer. Cell biologists... view more... (2002-01-24)
JILA finds flaw in model describing DNA elasticity
DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. view more (2007-09-17)
NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm. view more (2006-12-08)
Comparing chimp and human DNA
Scientists look to the chimpanzee genome to better understand what is uniquely human about our own. One goal is to find DNA elements that show evidence of rapid evolution in the human lineage. view more (2006-10-13)
Genetic Studies at University of Leicester Advance DNA Profiling and Research Into Child Abuse
PhD student Eleanor Graham presented a paper on the "Determination of the distribution of DNA to the faces of children aged 0-5 years due to normal day-to-day interaction between the child and the carers." Her fellow Leicester authors were Vicky Bowyer, also a PhD Student and Professor Guy Rutty, with Sabine Maguire and Beverley Ellaway... view more... (2005-05-11)
Dog's place and date of birth identified
Earlier studies of this field have shown that Eastern Asia is the place where the wolf was tamed to become the dog. view more (2009-09-01)
Detection of DNA on nanotubes offers new sensing, sequencing technologies
Researchers at the University of Illinois at Urbana-Champaign who recently reported that DNA-wrapped carbon nanotubes could serve as sensors in living cells now say the tiny tubes can be used to target specific DNA sequences. view more (2006-02-22)
Study: DNA barcoding in danger of 'ringing up' wrong species
DNA barcoding is a movement to catalog all life on earth by a simple standardized genetic tag, similar to stores labeling products with unique barcodes. The effort promises foolproof food inspection, improved border security, and better defenses against disease-causing insects, among many other applications. view more (2008-08-26)
Early Promise Of Non-Invasive Test For Colorectal Cancer (p 403)
A fast-track research letter in this week's issue of THE LANCET describes how the detection of a specific mutation in faecal DNA could be a reliable method for identifying a subset of proximal colorectal cancers. If successful, the new assessment, when combined with sigmoidoscopy or other DNA-based tests, could be advantageous over more difficult... view more... (2002-01-30)
Embryonic stem cells accrue genetic changes
An international team of researchers has discovered that human embryonic stem cell lines accumulate changes in their genetic material over time. view more (2005-09-06)
New cheaper method for mapping disease genes
Scientists at the Swedish medical university Karolinska Institutet have developed a new DNA-sequencing method that is much cheaper than those currently in use in laboratories. They hope that this new method will make it possible to map disease genes in large patient groups, which in turn can mean quicker breakthroughs for new treatments for a wide... view more...

DNA editing tool flips its target
Imagine having to copy an entire book by hand without missing a comma. Our cells face a similar task every time they divide. They must duplicate both their DNA and a subtle pattern of punctuation-like modifications on the DNA known as methylation. view more (2008-09-04)
DOE JGI sequences DNA from extinct cave bear
The genomic DNA sequencing of an extinct Pleistocene cave bear species-the kind of stuff once reserved for science fiction-has been logged into scientific literature thanks to investigators from the U.S. Department of Energy (DOE) Joint Genome Institute (JGI). view more (2005-06-03)
Bacteria change 'fingerprints' and baffle detectives
Tracing the source of a campylobacter food poisoning outbreak can be very difficult even with modern DNA fingerprinting methods. There is now evidence that campylobacters can rearrange their DNA, disguising their fingerprint, and confusing such detective work, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for... view more...

Damage to sperm DNA affects older men's chances of fathering children
Damage to DNA in sperm is significantly higher in older men than in those who are younger, according to research presented today (Tuesday 21 June 2005) at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-21)
Northwestern biologists demote Southeast Asia's 'forest ox'
It was one of the most famous discoveries of the 20th century. Shrouded in mystery since its recognition as a new species in 1937, the kouprey - an ox with dramatic, curving horns - has been an icon of Southeast Asian conservation. Feared extinct, it's been the object of perilous expeditions to the region's jungles by adventurers, scientists and... view more... (2006-09-18)
Native Americans Descended From a Single Ancestral Group, DNA Study Confirms
For two decades, researchers have been using a growing volume of genetic data to debate whether ancestors of Native Americans emigrated to the New World in one wave or successive waves, or from one ancestral Asian population or a number of different populations. view more (2009-04-29)
