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).

Study finds link between long-term dietary patterns and human gut bacteria

"You are what you eat" is familiar enough, but how deep do the implications go? An interdisciplinary group of investigators from the Perelman School of Medicine at the University of Pennsylvania have found an association between long-term dietary patterns and the bacteria of the human gut.

Researchers discover mechanisms behind BRCA1 gene mutations in breast and ovarian cancer

It is widely known that mutations in the breast cancer susceptibility 1 (BRCA1) gene significantly increase the chance of developing breast and ovarian cancers, but the mechanisms at play are not fully understood. Now, researchers at Virginia Commonwealth University Massey Cancer Center have shown that certain BRCA1 mutations result in excessive, uncontrolled DNA repair, which challenges the prior assumption that mutations in BRCA1 only contribute to breast cancer through a reduction in function.

New research puts an unexpected twist on how mitochondria divide within cells

New research from the University of California, Davis, and the University of Colorado at Boulder puts an unexpected twist on how mitochondria, the energy-generating structures within cells, divide.

Contraceptive pill prevents loss of eye sight

Scientists at University College Cork (UCC) have shown that the active component (Norgestrel) of the contraceptive 'Mini Pill' prevents the loss of sight in mice that have degenerative eye conditions that normally lead to blindness.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Ancient antibiotic resistance findings leads experts to stress need to use antibiotics sparingly

"An analysis of 30,000-year-old bacteria whose DNA has been recovered from the Yukon permafrost shows that they were able to resist antibiotics," providing "the first direct evidence that antibiotic resistance is a widespread natural phenomenon that preceded the modern medical use of antibiotics," according to a study in Thursday's issue of the journal Nature, the New York Times reports.

Older dads have a higher risk of having kids with mental disorders: Study

According to a new study children of older fathers have genetic changes associated with autism and other brain disorders. As of now this is seen only in lab mice. Professor John McGrath of the Queensland University’s Brain Institute and colleagues report their findings today in the journal Translational Psychiatry.

Mayo Clinic identifies new benefit of social media and online networks for rare diseases research

Mayo Clinic has identified a new benefit of social media and online networking: a novel way to study rare diseases. Through patient-run websites dedicated to heart conditions and women's heart health, a team of cardiologists led by Sharonne Hayes, M.D., is reaching out to survivors of spontaneous coronary artery dissection, also known as SCAD, a poorly understood heart condition that affects just a few thousand Americans every year.

Dad's stress can affect unborn children

Does Dad's stress affect his unborn children? According to the results of a new study in Elsevier's Biological Psychiatry, it seems the answer may be "yes, but it's complicated".

Stanford method identifies essential regions of Caulobacter's genome

A team at the Stanford University School of Medicine has cataloged, down to the letter, exactly what parts of the genetic code are essential for survival in one bacterial species, Caulobacter crescentus.

Scientists using molecular epidemiology to diagnose and track disease outbreaks

The New York Times examines "new methods of quickly sequencing entire microbial genomes that are revolutionizing the field" of molecularly epidemiology and could help public health officials identify and track disease outbreaks.

Parental stress strongly associated with DNA methylation in children

Researchers at the University of British Columbia and the Child & Family Research Institute have shown that parental stress during their children's early years can leave an imprint on their sons' or daughters' genes - an imprint that lasts into adolescence and may affect how these genes are expressed later in life.

Study may help explain plague's rapid evolution and aid in development of therapeutics

In the evolutionary blink of an eye, a bacterium that causes mild stomach irritation evolved into a deadly assassin responsible for the most devastating pandemics in human history. How did the mild-mannered Yersinia pseudotuberculosis become Yersinia pestis, more commonly known as the Plague?

ZIOPHARM initiates ZIN ATI-001 Phase 1 clinical study in advanced melanoma

ZIOPHARM Oncology, Inc. today announced that the first patient has been dosed in a Phase 1 clinical study of ZIN ATI-001, a novel DNA-based therapeutic candidate, in patients with advanced melanoma.

DNA sequencing pioneer, two pharmaceutical researchers recognized as ACS 'Heroes of Chemistry'

Two scientists developed a new drug that helped pioneer the era of "personalized medicine" for cancer patients, an approach in which one-size-fits-all drugs yield to medicines customized to the genetic endowment of individual patients. Another scientist invented today's predominant technology for genetic sequencing, deciphering the genetic blueprint in the DNA that makes up the genes of living things.

Genetic analysis of medieval plague skeletons proves the presence of y. pestis bacteria

Genetic analysis of medieval plague skeletons proves the presence of yersinia pestis bacteria. Collaboration between the University of Tübingen and Canadian scientists proves today's plague pathogen has been around at least 600 years.
