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).

Mayo Clinic study: High-intensity aerobic exercise can reverse cellular aspects of aging

Everyone knows that exercise is good for you, but what type of training helps most, especially when you're older -- say over 65? A Mayo Clinic study says it's high-intensity aerobic exercise, which can reverse some cellular aspects of aging. The findings appear in Cell Metabolism.

Discovery of link between RNA quality control and longevity may shed light on mechanisms behind aging

The vigors of youth and the greener pastures of yesteryears. Some might refer to these and other similar clichés as nothing more than rose-tinted literations of the past; a cognitive side effect of life.

Researchers discover genetic bases of Opitz C syndrome

Opitz C syndrome is a genetic disease that causes severe disabilities in patients and has been diagnosed in three people in the Iberian Peninsula, and sixty people in the world.

Researchers complete design phase for fully synthetic yeast genome

Working as part of an international research consortium, a multidisciplinary team at The Johns Hopkins University has completed the design phase for a fully synthetic yeast genome.

Scientists pinpoint key biological mechanism that can prevent proliferation of insulin-producing cells

If you become resistant to insulin, a condition that is a precursor to type 2 diabetes, your body tries to compensate by producing more of the "beta" cells in the pancreas that produce the critical hormone.

Innovative technology could aid in detecting recurrence of cancers

OICR researchers, together with international collaborators, have invented a technique to avoid a major problem with common laboratory techniques and improve the sensitivity of important cancer tests.

Scientists find evidence for gene that may be linked to social phobia

People with social anxiety avoid situations in which they are exposed to judgment by others. Those affected also lead a withdrawn life and maintain contact above all on the Internet.

TSRI researchers develop new drug candidates to target prostate and triple negative breast cancers

Scientists on the Florida campus of The Scripps Research Institute (TSRI) have designed two new drug candidates to target prostate and triple negative breast cancers.

New study shows how activation of innate immunity promotes tissue regeneration

Houston Methodist researchers have identified an immune pathway that promotes the formation of a cell that can develop into new tissues and organs.

New biomarkers may help in diagnosis and management of Crohn's disease

The diagnosis, understanding and management of Crohn's disease may have just received a helping hand from a joint ASU Biodesign Institute and Mayo Clinic study aimed at developing a better blood test for the disease.

Factors contributing to childhood adiposity begin before birth, study shows

A new article, published in the journal BMC Medicine, reports the largest epigenome-wide association study to date that provides evidence that factors contributing to childhood adiposity (level of body fat) begin before birth and are influenced by mother’s lifestyle, and fetal genetic and epigenetic factors.

Dental plaque DNA of Neandertals provides insights into behaviour, diet and medication

Ancient DNA found in the dental plaque of Neandertals - our nearest extinct relative - has provided remarkable new insights into their behaviour, diet and evolutionary history, including their use of plant-based medicine to treat pain and illness.

Scientists move closer towards simpler, accurate detection of bacterial contaminants in food and water

Food poisoning is a scourge. Yet preventing it is far from foolproof. But in a new study in Analytical Chemistry, scientists report that they are closing in on a way to use a combination of color-changing paper and electrochemical analysis -- on plastic transparency sheets or simple paper -- to quickly, cheaply and more accurately detect bacterial contamination of fruits and vegetables in the field before they reach grocery stores, restaurants and household pantries.

SETD8 enzyme protects against cellular senescence, research reveals

An enzyme that blocks cellular senescence and its mechanisms has been discovered by a research team from Kumamoto University, Japan. They found that a reduction of the enzyme SETD8, which regulates cell proliferation and gene function, results in the promotion of cell aging features.

Researchers develop innovative nanobiodevice that enables rapid detection of cancer biomarker

Like DNA, ribonucleic acid (RNA) is a type of polymeric biomolecule essential for life, playing important roles in gene processing.

Penn researchers identify genome-wide changes caused by high-fat diet

By comparing two strains of mice -- one that becomes obese and diabetic on a high-fat diet and another resistant to a high-fat regimen -- researchers from the Perelman School of Medicine at the University of Pennsylvania identified genome-wide changes caused by a high-fat diet.
