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 forensic method to identify criminals from a single strand of hair

During the investigations of crime scenes, even a single strand of human hair can make a significant difference in the evolution of a trial or case.

Researcher investigates the effects of wildfires on soil fungi

In the wake of the 2017 North Bay fires, the golden hills of Santa Rosa, California, were unrecognizable. Smoky, seared and buried under ash, the landscape appeared desolate, save for some ghostly, blackened - but still alive - oak trees.

Glyphosate could be used as biomarkers to predict incurring diseases in future generations

Exposure to the widely used weed-killer glyphosate makes genetic changes to rats that can be linked to increased disease in their grandchildren and great-grandchildren, a new study has found.

Repair proteins can help healthy cells to avoid damage during cancer therapy

A key way radiation therapy and chemotherapy work is by making highly lethal double-strand breaks in the DNA of cancer cells.

Within A Hair's Breadth--Forensic Identification Of Single Dyed Hair Strand Now Possible

In crime scene investigations, a single strand of hair can make a huge difference in the evolution of a case or trial.

Research clarifies regulatory impacts of ubiquitin-proteasome system on DNA damage repair

An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system (*1) in recognizing and repairing DNA that has been damaged by ultraviolet (UV) light.

Tumor DNA in DLBCL patient's stem cells or blood can predict risk of relapse after transplant

Many patients with diffuse large B-cell lymphoma (DLBCL) can be cured by a transplant using their own blood-forming stem cells, but as many as half eventually relapse. New research led by Dana-Farber Cancer Institute scientists suggests that patients whose blood or stem cell samples harbor tumor DNA are likely to relapse.

Researchers demonstrate strategy to control chemical reactions using antibodies

Antibodies are remarkable biomarkers: they are the cues that provide us with indications about many diseases and how our immune system counter them. Now a group of scientists from the University of Rome, Tor Vergata (Italy) has found a way to repurpose them so that they can trigger a specific chemical reaction.

New method could help resolve unwanted genetic changes associated with CRISPR-Cas9 technique

A research team has used a novel method that could help resolve the issue of unnecessary genetic changes encountered in the CRISPR-Cas9 technique.

Researchers identify genes that determine the shelf life of flaxseed oil

Biologists have analyzed the genes that establish the composition of fatty acids in flaxseed oil and detected polymorphisms in six of those genes.

Researchers evaluate the rate of eDNA sampling to identify species abundance in natural aquatic habitats

Organisms typically discharge DNA in their environments through sloughed skin cells, and this genetic material is called environmental DNA, or eDNA for short.

CRISPR-based test for COVID-19 provides quick, accurate results

Imagine swabbing your nostrils, putting the swab in a device, and getting a read-out on your phone in 15 to 30 minutes that tells you if you are infected with the COVID-19 virus.

Study explains new associations between Neanderthal DNA and autoimmune diseases

A researcher at the University of Tartu described new associations between Neanderthal DNA and autoimmune diseases, prostate cancer and type 2 diabetes.

Single-walled nanotubes emit delayed secondary fluorescence when triggered by multistep process

That carbon nanotubes fluoresce is no longer a surprise. Finding a second level of fluorescence is surprising and potentially useful.

Study may lead to novel organisms that are more efficient at converting plants into biofuels

A new study reveals how bacteria control the chemicals produced from consuming 'food.' The insight could lead to organisms that are more efficient at converting plants into biofuels.

Scientists propose a simple model for gene regulation in higher organisms

Although the DNA and its double-helix are some of the most familiar molecules of our time, our knowledge of how cells control what genes they want to express still is rather limited. In order to create, for example, an enzyme, the information that's inscribed in our DNA about this enzyme needs to be transcribed and translated.

Researchers determine 3D structures of RNA hybridization with artificial nucleic acids

As medical research progresses, traditional treatment protocols are being rapidly exhausted. New approaches to treat diseases that do not respond to conventional drugs are the need of the hour.

Research reveals fundamental insights into the causes of severe birth defects

Research by Kai Jiao, M.D., Ph.D., and colleagues at the University of Alabama at Birmingham and in Germany has yielded fundamental insights into the causes of severe birth defects known as CHARGE syndrome cases. These congenital birth defects include severe and life-threatening heart malformations.

Researchers create high-quality reference genome to improve traits in tomato

Thousands of years ago, people in South America began domesticating Solanum pimpinellifolium, a weedy plant with small, intensely flavored fruit. Over time, the plant evolved into S. Lycopersicum - the modern cultivated tomato.

Study confirms that telomere shortening helps prevent cancer in humans

As time goes by, the tips of your chromosomes--called telomeres--become shorter. This process has long been viewed as an unwanted side-effect of aging, but a recent study shows it is in fact good for you.
