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 mouse models may open ways to develop therapies for ALS patients

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive, fatal neurological disease that attacks the nerve cells controlling voluntary muscles. No effective treatments have been found.

Stanford researchers discover new biological markers to measure progression of Huntington's disease

Researchers at Stanford University School of Medicine have identified several new biological markers to measure the progression of the inherited neurodegenerative disorder Huntington's disease (HD).

Clinical study to test safety and ability of investigational Zika vaccine candidate begins

The first of five early stage clinical trials to test the safety and ability of an investigational Zika vaccine candidate called the Zika Purified Inactivated Virus (ZPIV) vaccine to generate an immune system response has begun at the Walter Reed Army Institute of Research Clinical Trial Center in Silver Spring, Maryland.

Suppressing bone specific protein can alleviate radiotherapy-induced osteoporosis

Radiotherapy destroys cancer cells using high-energy ionizing radiation to damage DNA and induce cell death. About two million patients per year in the United States - more than 50 percent of all cancer patients -- receive radiotherapy at some stage during their illness, either alone or in combination with chemotherapy, surgery, and targeted medicines.

Researchers discover set of immune proteins that facilitate long-lasting immunity against malaria

Houston Methodist researchers have discovered a set of immune proteins that facilitate long-lasting immunity against malaria.

New treatment with therapeutic short interfering RNA could help thwart cancer

In the fight against cancer, doctors dish out combination-blows of surgery, chemotherapy and other drugs to beat back a merciless foe. Now, scientists have taken early steps toward adding a stinging punch to clinicians' repertoire.

UNC scientists find clue that may help explain why people differ in ability to survive arterial blockages

Researchers at the University of North Carolina School of Medicine have found a major clue that may explain why some people sustain relatively little damage from strokes or heart attacks despite severe arterial blockages.

Researchers create detailed blueprint of how the body transports zinc to maintain good health

Zinc is essential for wound healing, for vision, for DNA creation, for our senses of taste and smell, even for sexual health. But despite its importance, scientists have never fully understood the mechanism that moves the mineral through the body - until now.

Vitamin B12 deficiency during pregnancy may predispose children to type-2 diabetes

B12 deficiency during pregnancy may predispose children to metabolic problems such as type-2 diabetes, according to research presented today at the Society for Endocrinology's annual Conference in Brighton.

Scientists develop new molecular method for detecting parasite in ham that causes toxoplasmosis

Scientists from the universities of Granada and Valencia have developed a new molecular method for determining the presence of the parasite Toxoplasma gondii, which causes toxoplasmosis, in samples of ham.

New study examines genetic factors underlying poor tolerance to shift work

Some people adapt easily to shift work, but not everyone can handle constant disruptions to their daily rhythm. Finnish researchers have now found that a melatonin receptor gene influences tolerance to shift work.

Smoking causes added mutations in DNA of lung cells

A paper published today in Science shows that smoking tobacco causes added mutations in the DNA of lung cells and in the DNA of other cells in the body. This is the first study to show the process by which smoking causes these cancers.

Ebola mutation increased infectivity

New research finds a genetic mutation in the Ebola virus that enabled it to target human cells more effectively during the recent Ebola epidemic.

Genetic variation, environmental conditions can have significant impact on human health

Scientists at the Wayne State University School of Medicine's Center for Molecular Medicine and Genetics have shown for the first time the extent by which interactions between environmental exposures and genetic variation across individuals have a significant impact on human traits and diseases like diabetes, heart disease and obesity, strengthening the case for precision medicine initiatives.

Problems with nuclear membrane play role in leukemia, heart disease and aging disorders

We put things into a container to keep them organized and safe. In cells, the nucleus has a similar role: keeping DNA protected and intact within an enveloping membrane.

New digital X-Ray detector uses novel photonics technology to make diagnosis safer for patients, hospital

A European health consortium is developing a set of low radiation, low cost, flat panel X-ray detectors that use novel photonics technology to make diagnosis safer for patients, hospital and dental staff, generating some of the highest resolution images ever seen in rapid moving body functions, such as malicious growths or the beating heart of a baby.
