Computer simulation shows buckyballs deform DNA
Soccer-ball-shaped "buckyballs" are the most famous players on the nanoscale field, presenting tantalizing prospects of revolutionizing medicine and the computer industry. view more (2005-12-06)
Little known DNA repair enzyme may be a tumor suppressor gene
The DNA in our cells is constantly being bombarded by environmental, chemical and cellular insults. Fortunately, our cells contain many enzymes devoted strictly to detecting and repairing any damage caused by these insults. view more (2006-01-04)
Researchers assemble second non-human primate genome
A multi-center team has deposited the draft genome sequence of the rhesus macaque monkey into free public databases for use by the worldwide research community, the National Human Genome Research Institute (NHGRI). view more (2006-02-10)
Ocean invaders in deep time
Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time? Luiz Rocha leads geneticists who time travel through ocean environments. view more (2005-10-14)
Human embryonic stem cells display a unique pattern of chemical modification to DNA
Scientists from the Burnham Institute for Medical Research (BIMR) and Illumina Inc., in collaboration with stem cell researchers around the world, have found that the DNA of human embryonic stem cells is chemically modified in a characteristic, predictable pattern. view more (2006-08-07)
UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. view more (2005-10-20)
ASU researchers 'wire' DNA to identify mutations
A team of ASU researchers led by Nongjian Tao and Peiming Zhang has developed a new, breakthrough technique for the detection of DNA mutations. view more (2005-12-09)
Mechanism controlling DNA damage response has potential novel medical applications
Investigators at St. Jude Children's Research Hospital have discovered a previously unrecognized mechanism that controls a key protein linked to the cell's response to stress-a finding that holds promise for new ways to enhance cancer therapies or protect cells from dying after exposure to damaging chemicals or radiation. view more (2005-10-07)
Bread mold may hold secret to eliminating disease-causing genes
When most people discover mold on their bread, they immediately throw it out. Others see a world of possibilities in the tiny fungus. A University of Missouri scientist, along with a collaborative research team, has examined a new mechanism in the reproductive cycle of a certain species of mold. view more (2008-05-09)
Woolly mammoth genome comes to life
A McMaster University geneticist, in collaboration with genome researchers from Penn State University and the American Museum of Natural History has made history by mapping a portion of the woolly mammoth's genome. view more (2005-12-23)
Damage from oxygen may be one cause of Parkinson's disease
Research by neuroscientists at the University of Virginia Health System shows that oxygen free radicals are damaging proteins in mitochondria, the tiny cellular 'batteries' of brain cells. view more (2006-05-17)
New lipid molecule holds promise for gene therapy
Scientists at the University of California, Santa Barbara have created a new molecule that holds promise in fighting disease via gene therapy. view more (2006-03-23)
Genetic variation: We're more different than we thought
New research shows that at least 10 percent of genes in the human population can vary in the number of copies of DNA sequences they contain-a finding that alters current thinking that the DNA of any two humans is 99.9 percent similar in content and identity. view more (2006-11-27)
New DNA 'fingerprinting' technique separates hemp from marijuana
Using new DNA "fingerprinting" techniques, two University of Minnesota researchers have become the first to unequivocally separate hemp plants from marijuana plants with genetic markers. view more (2006-03-23)
Immune system response to viral DNA is unique
The human body has a unique immune system response to foreign DNA, suggesting that DNA viruses and RNA viruses are detected by different mechanisms. view more (2006-01-25)
Junk DNA may not be so junky after all
Researchers at the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins have invented a cost-effective and highly efficient way of analyzing what many have termed "junk" DNA and identified regions critical for controlling gene function. view more (2006-03-24)
Ancient trans-Atlantic swarm brought locusts to the new world
Somewhere between three and five million years ago, a massive swarm of locusts took off from the west coast of Africa and made an unlikely voyage across the Atlantic Ocean to colonize the New World, says an international team of researchers. view more (2005-12-21)
Gold nanoparticles could improve antisense cancer drugs
In the fight against cancer, antisense drugs, which prevent genes from producing harmful proteins such as those that cause cancer, have the promise to be more effective than conventional drugs, but the pace of development of these new drugs has been slow. view more (2006-05-19)
Controversial findings help explain evolution of life
Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry. view more (2006-04-07)
MicroRNAs play a big part in gene regulation-and evolution
egulating when and where certain proteins are made is crucial to the normal functioning of living things. To make proteins, information from DNA is transcribed into RNA molecules and then translated into the amino acids building blocks of proteins. view more (2005-06-24)
