DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Discovery of new tumor suppressor gene

National Institutes of Health (NIH) researchers have identified a gene that suppresses tumor growth in melanoma, the deadliest form of skin cancer.

Cepheid announces new TB test for use in developing countries

The Sunnyvale, Calif.-based company Cepheid on Tuesday announced it has developed a rapid diagnostic test for tuberculosis that it will sell at a reduced cost in developing countries, the San Francisco Chronicle reports. The test was developed in partnership with the Foundation for Innovative New Diagnostics, the University of Medicine and Dentistry of New Jersey, and the National Institute of Allergy and Infectious Diseases.

DNA-based assembly line for precision nano-cluster construction

Building on the idea of using DNA to link up nanoparticles - particles measuring mere billionths of a meter - scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a molecular assembly line for predictable, high-precision nano-construction.

New way to make stem cells avoids risk of cancer

A team of scientists has advanced stem cell research by finding a way to endow human skin cells with embryonic stem cell-like properties without inserting potentially problematic new genes into their DNA.

DNA repair mechanisms relocate in response to stress

Like doctors making house calls, some DNA repair enzymes can relocate to the part of the cell that needs their help, a collaborative team of scientists at Emory University School of Medicine has found.

Mutations in a gene may stunt lung development in children

Mutations in a gene may cause poor lung development in children, making them more vulnerable to diseases such as chronic obstructive pulmonary disease (COPD) later in life, say researchers at the University of Pittsburgh Graduate School of Public Health and the German Research Center for Environmental Health.

Nanoparticles deliver gene therapy, killing tumors

Given that cancer is ultimately a genetic disease, it has long been the hope of researchers to use gene therapy to attack tumors where they might be most susceptible.

The egg makes sure that sperm don't get too old

In contrast to women, men are fertile throughout life, but research at the Sahlgrenska Academy, University of Gothenburg, Sweden, has now shown that a fertilising sperm can get help from the egg to rejuvenate. The result is an important step towards future stem cell therapy.

Ovarian cancers detected early may be less aggressive, questioning effectiveness of screening

The biology of ovarian cancers discovered at an early stage may render them slower growing and less likely to spread than more aggressive cancers, which typically are discovered in an advanced stage, according to a study led by investigators in the Duke Comprehensive Cancer Center.

Discovery of major new risk factor for melanoma in young women

Researchers may have found a more potent risk factor for melanoma than blistering sunburns, freckling, or family history of the deadly skin disease.

New strategy for fighting persistent bacterial infections

Researchers at National Jewish Health have discovered a promising strategy for destroying the molecular scaffolding that can make Pseudomonas bacterial infections extremely difficult to treat in cystic fibrosis patients, wearers of contact lenses, and burn victims.
