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)
New light trap captures larval stage of new species; DNA barcode technology used
When David Jones, a fisheries oceanographer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) located at the University of Miami's Rosenstiel School, set out to design a better light trap to collect young reef fishes, he never imagined his invention would contribute to the discovery of a new species. view more (2007-10-24)
Saved by junk DNA
VIB researchers linked to K.U.Leuven and Harvard University show that stretches of DNA previously believed to be useless 'junk' DNA play a vital role in the evolution of our genome. view more (2009-05-29)
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)
Junk DNA may prove invaluable in quest for gene therapies
Scientists have identified how a protein enables sections of so-called junk DNA to be cut and pasted within genetic code - a finding which could speed development of gene therapies. view more (2009-09-22)
Embryonic heart exhibits impressive regenerative capacity
A new study demonstrates that the embryonic mouse heart has an astounding capacity to regenerate, a phenomenon previously observed only in non-mammalian species. view more (2008-10-14)
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)
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)
St. Jude researchers find key step in programmed cell death
Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process. view more (2008-03-03)
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)
CU-Boulder team identifies DNA barcodes to help track illegal trading of wildlife products
Researchers from several institutions including the University of Colorado at Boulder have sequenced DNA "barcodes" for as many as 25 hunted wildlife species, providing information that can be used to better monitor the elusive trade of wildlife products, or bushmeat. view more (2009-09-16)
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)
Different coat color may not mean different species for lemurs
Researchers have found that lemurs suspected to belong to different species because of their strikingly different coat colors, are not only genetically alike, but belong to the same species. view more (2006-11-16)
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)
