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).

Scientists find potent agent that thwarts drug resistance in malaria parasite

Scientists have made an important breakthrough in the fight against malaria, identifying a potent agent that thwarts drug resistance in the parasite that causes the disease.

New research reveals how DNA influences severity of any genetic disease

That two people with the same disease-causing mutation do not get sick to the same extent has been puzzling scientists for decades. Now Professor Andy Fraser and his team have uncovered a key part of what makes every patient different.

Type 2 diabetes patients with specific genetic markers at higher risk of developing Alzheimer's disease

Certain patients with type 2 diabetes (T2D) may have specific genetic risk factors that put them at higher risk for developing Alzheimer's disease (AD), according to a study conducted at the Icahn School of Medicine at Mount Sinai and published recently in Molecular Aspects of Medicine.

Changes in body temperature can cause sudden cardiac death, finds SFU research

Scientists, including SFU professor Peter Ruben, have found that sudden death caused by cardiac arrhythmia can be triggered by changes in body temperature. The study is published in the Journal of Physiology.

Noninvasive prenatal testing clue to maternal malignancy

A preliminary study lends support to the hypothesis that a false-positive noninvasive prenatal test finding could be due to the presence of an occult maternal cancer.

New drug DSM265 shows potential to cure, prevent malaria

Researchers at UT Southwestern Medical Center and in Australia have shown that a drug currently in testing shows potential to cure malaria in a single dose and offers promise as a preventive treatment as well.

Various freshwater sources in Georgia pose possible risk for salmonella infections

Researchers from the University of Georgia have determined that various freshwater sources in Georgia, such as rivers and lakes, could feature levels of salmonella that pose a risk to humans.

Study stresses importance of investigating telomeres to improve diagnoses, develop treatments for many diseases

Studying telomeres, the structures that protect the ends of chromosomes, has become a key issue in biology. In recent years, not only has their relation to ageing been confirmed; defective telomeres seem to be linked to more and more illnesses, including many types of cancer.

New hand-held paper machine could be used for point-of-care detection of infectious diseases, cancer

In the U.S. and other industrialized nations, testing for infectious diseases and cancer often requires expensive equipment and highly trained specialists. In countries where resources are limited, performing the same diagnostics is far more challenging. To address this disparity, scientists are developing a portable, low-cost "paper machine" for point-of-care detection of infectious diseases, genetic conditions and cancer.

Research breakthrough opens door to a world of regenerative medicine for treating mitochondrial disease

A study led by Shoukhrat Mitalipov, Ph.D., and Hong Ma, M.D., Ph.D., at the Center for Embryonic Cell and Gene Therapy at Oregon Health & Science University and the Oregon National Primate Research Center has revealed the first critical step in developing novel gene and stem cell therapy treatments for patients with mitochondrial disease.

Research could lead to new approaches to treating spinal cord and brain injuries

Many an injury will heal, but the damaged spinal cord is notoriously recalcitrant. There's new hope on the horizon, though. A team of researchers led by the University of South Carolina's Jeff Twiss just reported an innate repair mechanism in central nervous system axons that might be harnessed to regenerate nerves after brain or spinal cord injuries.
