Why eating less can help the environment
An estimated 19 percent of total energy used in the USA is taken up in the production and supply of food. Currently, this mostly comes from non-renewable energy sources which are in short supply. view more (2008-07-24)
Researchers solve piece of large-scale gene silencing mystery
A team led by Craig Pikaard, Ph.D., Washington University in St. Louis professor of biology in Arts & Sciences, has made a breakthrough in understanding the phenomenon of nucleolar dominance, the silencing of an entire parental set of ribosomal RNA genes in a hybrid plant or animal. view more (2008-12-05)
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)
Single-stranded DNA-binding protein is dynamic, critical to DNA repair
Researchers report that a single-stranded DNA-binding protein (SSB), once thought to be a static player among the many molecules that interact with DNA, actually moves back and forth along single-stranded DNA, gradually allowing other proteins to repair, recombine or replicate the strands. view more (2009-10-22)
University of Strathclyde DNA researcher wins Royal Society of Chemistry Award
A DNA researcher at the University of Strathclyde has been awarded over £200,000 by the Royal Society of Chemistry. Dr Duncan Graham has won the prestigious Analytical Grand Prix Fellowship in recognition of his groundbreaking research into DNA diagnostics. Dr Graham`s winning entry involves a new technique, SERRS* technology, which is... view more... (2002-09-04)
Stress could damage DNA
A ground-breaking experiment has suggested that a certain type of stress could actually damage humans' DNA. view more (2004-08-23)
Why does an anti-anthrax drug kill plants too?
Scientists at the John Innes Centre (JIC), Norwich (1) have today reported that a very successful antibiotic, which is harmless to humans but lethal to most bacteria, also kills plants. They have found that an enzyme, which is an important target for several families of antibiotics and was thought to exist only in bacteria, is also present in... view more... (2004-05-12)
Linking DNA and histone methylation
In the May 15th issue of G&D, Dr. Michael Carey (UCLA's Jonsson Comprehensive Cancer Center) and colleagues lend new insight into the mechanism of epigenetic silencing of euchromatic genes. view more (2007-04-30)
Gene-bender proteins may sway to DNA
Among the many genes packed into each cell of our body, those that get turned on, or expressed, are the ones that make us who we are. Certain proteins do the job of regulating gene expression by clasping onto key spots of DNA - the nucleic acid that contains the genetic instructions. view more (2006-12-05)
Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription
The distribution of the four nucleotides along the DNA sequence encodes the genetic information in living systems. However, do nucleic acids possess other attributes that contribute to their biological functions? view more (2007-03-14)
Boston University scientists develop new application to characterize structure of DNA molecules
A team of researchers from Boston University has developed a new application to enable more precise measurement of the location of a fluorescent label in a DNA layer. view more (2006-03-01)
Exploring the Dark Matter of the Genome
Not so long ago, the difficult-to-sequence, highly repetitive, gene-poor DNA found in regions of chromosomes known as heterochromatin was called "junk." Like dark matter in the universe, the true nature of heterochromatin was unknown. view more (2007-06-18)
Study shows Chronix technology using serum DNA can identify early presence of disease
Chronix Biomedical today reported that a new study in a peer-reviewed journal further confirms the potential diagnostic and prognostic utility of using circulating fragments of DNA to detect early stage disease. view more (2009-06-23)
Surprising new insights into the repair strategies of DNA
A microscopic single-celled organism, adapted to survive in some of the harshest environments on earth, could help scientists gain a better understanding of how cancer cells behave. view more (2009-07-16)
UNC scientists discover cellular 'SOS' signal in response to UV skin damage
New research from the University of North Carolina at Chapel Hill School of Medicine has identified two proteins that may help protect against skin cancer. view more (2007-03-19)
Blood test to predict diabetes in children
The researchers found that four out of five patients with juvenile diabetes have the so-called islet antibodies directed against GAD and IA2 in their blood before the condition manifests itself and that these proteins occur exclusively in cases of juvenile diabetes. The test measures the concentration of the islet antibodies in the child's blood.... view more... (2000-01-18)
Centromeres cross over, a lot
Recombination at centromeres is higher than anywhere else on the chromosome, even though methyltransferases do their best to prevent it, say Jaco et al., as published in the June 16 issue of the Journal of Cell Biology. view more (2008-06-13)
Researchers test reliability of forensic DNA technology in fight against crime
Researchers from Barts and The London, Queen Mary`s School of Medicine and Dentistry are to team up with colleagues from universities in Germany, Spain and Denmark in a £1m European research collaboration to test DNA techniques used to solve crime. DNA is often used by forensic scientists to identify persons from physical evidence left... view more... (2002-07-26)
Genetic double-agents unmasked
Babraham Institute and Cancer Research UK scientists have discovered that certain enzymes with a key activity in the immune system may be important in stem-cell development, but may also work against us by contributing to the occurrence of cancer. view more (2004-10-26)
Handheld DNA detector
A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector. view more (2008-03-11)
