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)
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)
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)
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)
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)
9th International Congress on Obesity: information for the media
9th International Congress on Obesity August 24-29 2002 S'£o Paulo, Brazil Obesity is headline news almost every day of the week. Legal actions against junk food, talk of a "fat tax", rising levels of childhood obesity worldwide with the new added complication of type 2 diabetes emerging in youngsters, along with increasing pressure on the... view more...

Electronic structure of DNA revealed for 1st time by Hebrew University and collaborating researchers
Utilizing a technique that combines low temperature measurements and theoretical calculations, Hebrew University of Jerusalem scientists and others have revealed for the first time the electronic structure of single DNA molecules. view more (2008-02-29)
Gene packaging tells story of cancer development
To decipher how cancer develops, Johns Hopkins Kimmel Cancer Center investigators say researchers must take a closer look at the packaging. view more (2008-12-05)
New step in DNA damage response in neurons discovered
Researchers have identified a biochemical switch required for nerve cells to respond to DNA damage. view more (2009-01-20)
Ring-like formations in drying DNA drops could affect hybridization studies
Coffee drinkers are familiar with the ring-shaped stains that result from spilled drops that have dried, in which the brown stain is not evenly distributed, but instead concentrated at the edge. view more (2006-05-12)
Photonic crystal biosensors detect protein-DNA interactions
Scientists at the University of Illinois have developed a new class of disposable, microplate-based optical biosensors capable of detecting protein-DNA interactions. Based on the properties of photonic crystals, the biosensors are suitable for the rapid identification of inhibitors of protein-nucleic acid and protein-protein interactions. view more (2008-09-24)
Model unravels rules that govern how genes are switched on and off
For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off. Different genes operate in each cell type at different times, and this careful orchestration is what ultimately distinguishes a brain cell from a liver or skin cell. view more (2008-12-05)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
Trash or treasure? Discarded US computers often get a second life
More computers discarded by consumers in the United States are getting a second life in developing countries than previously believed, according to a new study -- the most comprehensive ever done on the topic. view more (2009-09-02)
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)
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)
