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).

New app for iPhone helps detect toxins, proteins, bacteria and viruses

Researchers and physicians in the field could soon run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones.

Researchers identify mutations in new genes that might be associated with ALS disease

Researchers at the Stanford University School of Medicine have identified mutations in several new genes that might be associated with the development of spontaneously occurring cases of the neurodegenerative disease known as amyotrophic lateral sclerosis, or ALS.

Study could open up new possibilities for early diagnosis of motor disorders

The scientists report these findings in the current online edition of "The Lancet Neurology". This pan-European study could open up new possibilities of early diagnosis and smooth the way for treatments which tackle diseases before the patient's nervous system is irreparably damaged.

New TGT method helps detect and measure mechanics of single-molecule interaction

Cells in the human body do not function in isolation. Living cells rely on communication with their environment-neighboring cells and the surrounding matrix-to activate a wide range of cellular functions, including reproduction of new cells, differentiation of stem cells into distinct cell types, cell adhesion, and migration of white blood cells to fight bodily infections.

New technique may help develop genetic thermometer to assess patients’ health

On May 22, JoVE will publish details of a technique to measure the health of human genetic material in relation to a patient-s age. The method is demonstrated by the laboratory of Dr. Gil Atzmon at New York-s Albert Einstein College of Medicine.

Study suggests possible way to halt cancer development in premalignant cells

Scientists have uncovered a survival mechanism that occurs in breast cells that have just turned premalignant-cells on the cusp between normalcy and cancers-which may lead to new methods of stopping tumors.

Highlights: Geography's role in elective surgeries in Calif.; Conn. Democrats eye shifting $400M in Medicaid money; HHS says Cedars-Sinai has $2.2M in billing errors

Geography plays a role in whether patients in California have elective operations such as joint replacement, weight loss surgery and gallbladder removal, according to a new study. The California HealthCare Foundation study showed wide variations in patient surgeries across the state (Gorman, 5/22).

Some aggressive forms of prostate cancer have similar genetic origins

Mayo Clinic researchers have used next generation genomic analysis to determine that some of the more aggressive prostate cancer tumors have similar genetic origins, which may help in predicting cancer progression. The findings appear online today in the journal Cancer Research.

Study identifies specific genetic factors that influence occurrence and severity of sepsis

A study published in the June issue of Anesthesiology represents an important first step in establishing new therapeutic options targeting specific genetic areas that influence the occurrence and severity of sepsis - a life-threatening, whole-body response to infection.

Long-term depression linked with life-threatening chronic disease, earlier death

The first symptoms of major depression may be behavioral, but the common mental illness is based in biology — and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk factors have been taken into account.

Cancer risk to increase following CT scans in younger patients, study reveals

Study leader, Professor John Mathews from the University of Melbourne said this small increase in cancer risk must be weighed against the undoubted benefits from CT scans in diagnosing and monitoring disease.

Viewpoints: Slowing health costs; What causes genetic testing to be so expensive; Iowa governor offers Medicaid supports a 'glimmer of hope'

We have done it. We have decreased the increase in the cost of healthcare. ... Is this decline the desperately needed bend in the healthcare cost curve or just the impact of the depressed economy? ... A slower growth of healthcare cost would mean less burden on the individual family, freeing that family to invest in and live a higher quality of life.

Rice University computational study tracks regulatory mechanisms of E. coli cells

Environment is not the only factor in shaping regulatory patterns -- and it might not even be the primary factor, according to a new Rice University study that looks at how cells' protein networks relate to a bacteria's genome.

Caltech biologists show that microRNA-146a protects stem cells during inflammation

When infections occur in the body, stem cells in the blood often jump into action by multiplying and differentiating into mature immune cells that can fight off illness. But repeated infections and inflammation can deplete these cell populations, potentially leading to the development of serious blood conditions such as cancer.
