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).

Resurrecting protein ancestors yields evolutionary insights into their role in human cells

"Resurrecting" the ancestors of key proteins yields evolutionary insights into their role in human cells and in most cancers, a new study finds.

DNA methylation may influence the effects of aspirin in patients with breast cancer

Women with a particular DNA feature may live longer if they take aspirin even before they are diagnosed with breast cancer, a new study found.

Scientists identify hereditary pancreatic cancer risk mutation

Scientists studying a highly cancer-prone family have identified a rare, inherited gene mutation that dramatically raises the lifetime risk of pancreatic and other cancers.

A newly-emerging species of C. difficile highly adapted to spread in hospitals

Scientists have discovered that the gut-infecting bacterium Clostridium difficile is evolving into two separate species, with one group highly adapted to spread in hospitals.

New test may improve the ability to diagnose riskiest forms of HPV infection

Ninety-nine percent of cervical cancers are caused by human papillomavirus (HPV). More than 200 HPVs, some of which are associated with varying degrees of cancer risk, complicate diagnosis and treatment.

Study reveals surprising discoveries about poorly understood glioblastoma

Glioblastoma, a cancer that arises in the brain's supporting glial cells, is one of the worst diagnoses a child can receive. The grade IV, highly malignant tumor aggressively infiltrates healthy brain tissue, and most children die of the disease within one to two years of diagnosis, similar to adults.

UAMS Myeloma Center receives $542,486 grant from Leukemia & Lymphoma Society

Brian Walker, Ph.D., with the Myeloma Center at the University of Arkansas for Medical Sciences has received a $542,486, three-year grant from the Leukemia & Lymphoma Society to look at changes in the DNA sequence that effects the development and advancement of multiple myeloma, a cancer of plasma cells in the blood.

Biologists discover the intricacies of 'on/off switch' that creates cell differentiation

A team of biologists has discovered how cells become different from each other during embryogenesis, a finding that offers new insights into genetic activity and has implications for better understanding the onset of disease and birth defects.

Study shows how dual DNA barcoding could help improve diagnosis of fungal infections

A new study from The Westmead Institute for Medical Research (WIMR) has demonstrated how dual DNA barcoding could help improve the diagnosis of invasive fungal diseases, giving patients access to potentially life-saving treatment much sooner.

New discovery could help doctors identify children at risk for Wilms’ tumor relapse

Today, researchers from MSK Kids at Memorial Sloan Kettering Cancer Center published results that examine elevated levels of a protein called prohibitin in the urine and tumors of children with Wilms' tumors.

New insights into emergent evolutionary potential and generative phenotype

In the cover photo, nature photographer Andreas Kay has captured one of the most striking examples of Batesian Mimicry in nature--first reported by Henry Walter Bates in 1861.

New technique finds medically and ecologically relevant bacteria groups

Identifying species among plants and animals has been a full-time occupation for some biologists, but the task is even more daunting for the myriad microbes that inhabit the planet.

Treatment with both targeted cancer therapy and MS drug halts glioblastoma stem cells

Glioblastoma is an aggressive form of brain cancer that infiltrates surrounding brain tissue, making it extremely difficult to treat with surgery.

A TARDIS could vastly improve detection of breast cancer

Scientists have devised a newer form of blood test called TARDIS to diagnose breast cancer more accurately. This could help many thousands of women avoid needless breast biopsies and removals, as well as helping to follow up the treatment of breast cancer.
