Scientists present the largest-to-date genetic snapshot of Iceland 1,000 years ago
Scientists at deCODE genetics have completed the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains, the study provides a detailed look at how a contemporary population differs from that of its ancestors.   view more (2009-01-16)

Scientists identify specific enzymes that make meningitis hard to fight
Two enzymes in meningitis bacteria which prevent the body from successfully fighting off the disease, and make the infection extremely virulent, have been identified in new research published today.   view more (2007-02-23)

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)

Scientists 'rebuild' giant moa using ancient DNA
Scientists have performed the first DNA-based reconstruction of the giant extinct moa bird, using prehistoric feathers recovered from caves and rock shelters in New Zealand.   view more (2009-07-02)

Unlocking the key to human fertility
Scientists at Leeds and Bradford have discovered a unique 'DNA signature' in human sperm, which may act as a key that unlocks an egg's fertility and triggers new life.   view more (2009-08-03)

Rethinking the genetic theory of inheritance
Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases.   view more (2009-01-20)

Salmonella survives better in stomach due to altered DNA
Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food. This type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics.   view more (2007-01-31)

New forensic science will identify Brazil's "disappeared"
Collaboration between forensic scientists from Sheffield and Brazil using a new DNA extraction technique has identified two homicide victims whose skeletonised bodies were found dumped in sugar cane plantations near S'£o Paulo in the late 1990s. The same technique is now to aid the task of identifying the remains of hundreds of victims of... view more... (2002-11-19)

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher
University of Pittsburgh researcher Alexander Star and colleagues at California-based company Nanomix, Inc., have developed devices made of carbon nanotubes that can find mutations in genes causing hereditary diseases.   view more (2006-01-26)

Light activated anticancer drug targeted to DNA using cisplatin like sub-units
One of the most effective chemotherapy drugs against cancer is cisplatin because it attaches to cancer DNA and disrupts repair.   view more (2006-03-27)

Penn researchers determine structure of smallpox virus protein bound to DNA
Researchers at the University of Pennsylvania School of Medicine have determined the structure of an important smallpox virus enzyme and how it binds to DNA.   view more (2006-08-07)

Study links high levels of nitric oxide to infertility and sperm DNA damage
Iranian scientists have linked a chemical that plays an essential role in many bodily functions to sperm DNA damage and male infertility.   view more (2006-06-19)

IUPUI scientists report first 3-D view of anti-cancer agent
Researchers from the Indiana University School of Medicine and the Purdue School of Science at Indiana University-Purdue University Indianapolis have created the first three-dimensional image of how a well-established chemotherapy agent targets and binds to DNA.   view more (2008-03-19)

A cancer gene causing tumours by a 'double-whammy' mechanism also reveals the key to a cure
Scientists at the Babraham Institute have discovered that a tiny change in a protein involved in cell survival is responsible for abnormal cell activity in the early stages of cancer. The protein, known as Bcl-xL, normally protects cells from dying; and when the DNA in cells becomes damaged, Bcl-xL is modified so that it no longer keeps the cells... view more... (2004-01-21)

2 heads are better than 1: 2 dysfunctional DNA repair pathways kill tumor cells
Individuals who inherit two mutant copies of any one of about 12 genes that make the proteins of the Fanconi Anemia (FA) pathway develop FA, which is characterized by increased incidence of cancer and bone marrow failure, among other things.   view more (2007-04-13)

Handle with care: Telomeres resemble DNA fragile sites
Telomeres, the repetitive sequences of DNA at the ends of linear chromosomes, have an important function: They protect vulnerable chromosome ends from molecular attack.   view more (2009-07-10)

Models begin to unravel how single DNA strands combine
Using computer simulations, a team of University of Wisconsin-Madison researchers has identified some of the pathways through which single complementary strands of DNA interact and combine to form the double helix.   view more (2009-10-07)

Detection of Salmonella in 24 hours
The food and drink we consume have to pass strict quality controls. Nevertheless, these measures are not always sufficient, given that sometimes certain foodstuffs can still give rise to food poisoning, most often caused by micro-organisms.   view more (2007-02-09)

Human DNA repair process recorded in action
A key phase in the repair process of damaged human DNA has been observed and visually recorded by a team of researchers at the University of California, Davis. The recordings provide new information about the role played by a protein known as Rad51, which is linked to breast cancer, in this complex and critical process.   view more (2009-01-29)

New tool probes function of rice genes
A new tool for investigating the rice genome has been developed by researchers at UC Davis led by Pamela Ronald, professor of plant pathology.   view more (2008-10-09)
