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 uncover new layer of information in the genetic code

A hidden and never before recognized layer of information in the genetic code has been uncovered by a team of scientists at the University of California, San Francisco (UCSF) thanks to a technique developed at UCSF called ribosome profiling, which enables the measurement of gene activity inside living cells - including the speed with which proteins are made.

New microfluidic chip more effective in detecting flu outbreaks

The H1N1 flu pandemic in 2009 underscored weaknesses in methods widely used to diagnose the flu, from frequent false negatives to long wait times for results. Now Boston University researchers have developed a prototype of a rapid, low-cost, accurate, point-of-care device that promises to provide clinicians with an effective tool to quickly diagnose both seasonal and pandemic strains of influenza, and thus limit the spread of infection.

IU biologist to genetically modify variants of chlamydia

An Indiana University biologist has been awarded over $2.3 million from the National Institutes of Health to genetically modify variants of the human pathogen chlamydia in hopes of finding a vaccine for the most commonly reported bacterial infectious disease in the United States.

Defects in schizophrenia-risk genes and environmental stress lead to abnormal brain development

Working with genetically engineered mice and the genomes of thousands of people with schizophrenia, researchers at Johns Hopkins say they now better understand how both nature and nurture can affect one's risks for schizophrenia and abnormal brain development in general.

Study reveals how HSV-1 virus overcomes intrinsic host defenses

New biological research reveals how an invading virus hijacks a cell's workings by imitating a signaling marker to defeat the body's defenses. By manipulating cell signals, the virus destroys a defensive protein designed to inhibit it. This finding, from studies in human cell cultures, may represent a broader targeting strategy used by other viruses, and may lay the scientific groundwork for developing more effective treatments for infectious diseases.

Lowering LDL at younger age can reduce risk of CHD

Coronary atherosclerosis - a hardening of the arteries due to a build-up of fat and cholesterol - can lead to heart attacks and other forms of coronary heart disease (CHD). Lowering low-density lipoprotein (LDL), or "bad" cholesterol, reduces the risk of CHD, and researchers found that lowering LDL beginning early in life resulted in a three-fold greater reduction in the risk of CHD than treatment with a statin started later in life, according to research presented today at the American College of Cardiology's 61st Annual Scientific Session.
