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 shows human genome regulates the early development of organs

A team of researchers has identified how the human genome regulates the development of several organs that are crucial to human life.

Using genetic engineering to study evolutionary assimilation of foreign DNA in a new host

All life is subject to evolution in the form of mutations that change the DNA sequence of an organism's offspring, after which natural selection allows the 'fittest' mutants to survive and pass on their genes to future generations.

Researchers use genome editing to facilitate drug discovery based on natural fungus

Rice University scientists have won federal support for their pursuit of novel drugs to treat human disease.

Researchers describe a previously unknown phylum of aquatic Archaea

In a publication in Nature Communications last Friday, NIOZ scientists Nina Dombrowski and Anja Spang and their collaboration partners describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation.

Researchers develop new method to diagnose brain tumor without incisions

Brain tumors are typically diagnosed using MRI imaging, as taking a sample for a tissue biopsy is risky and may not be possible due to tumor location or a patient's poor health conditions.

Genetic analysis reveals the inhibitory role of NSD2 enzyme in cellular senescence

Using a detailed genetic analysis, a research team from Japan-based Kumamoto University has discovered that the NSD2 enzyme, which controls the actions of several genes, also functions to block the aging of cells.

Increased blood lead levels in children are linked to reduced expression of genes

Researchers have revealed a connection between methylation of genes implicated in heme synthesis and carcinogenesis and high blood lead levels in children, signifying a previously unfamiliar mechanism for lead poisoning.

Test pinpoints which people with gonorrhea can be treated with ciprofloxacin

A test designed by UCLA researchers can pinpoint which people with gonorrhea will respond successfully to the inexpensive oral antibiotic ciprofloxacin, which had previously been sidelined over concerns the bacterium that causes the infection was becoming resistant to it.

Study shows how DNA from ancient ancestors was passed down to modern humans

According to a new study of ancient genomes, different branches of the human family tree could have interbred numerous times, and certain human beings carry DNA from an unfamiliar and ancient ancestor.

Agricultural Research Service releases genomic data of Asian giant hornets

The first complete genome of the Asian giant hornet has been released by a team of Agricultural Research Service (ARS) scientists.

Discovery Shows Promise For Treating Huntington's Disease

Huntington disease is a progressive debilitating brain disorder that causes uncontrolled movements, psychological problems, and loss of cognition.

Deep Learning On Cell Signaling Networks Establishes AI For Single-Cell Biology

Computer systems that emulate key aspects of human problem solving are commonly referred to as AI. This field has seen massive progress over the last years.

Scientists explore the role of epigenetic regulator factors in embryonic development

A research team at the Max Planck Institute for Molecular Genetics in Berlin has explored the role of factors in embryonic development that do not alter the sequence of DNA, but only epigenetically modify its "packaging".

New findings help to better understand the genetics of neuropsychiatric disorders

A new study led by NorthShore University HealthSystem (NorthShore) and the University of Chicago took a novel approach to identifying SNPs influencing the risk of neuropsychiatric disorders like schizophrenia, bipolar and major depressive disorder, the institutions announced today.

Newly discovered 'mutation fog' linked to normal DNA repair process

Hypermutation is an unusual occurence that can lead to many nearby mutations at once, severely damaging our genetic material and potentially causing cancer.

New study may offer a novel, potential target for treating breast cancer

According to researchers, G-quadruplexes have been demonstrated to play a crucial role in specific types of breast cancer for the first time.

Identifying a new genetic cause of inherited neuropathy

Inherited mutations in a gene that keeps nerve cells intact were shown, for the first time, to be a driver of neuropathy known as Charcot-Marie-Tooth disease.

Detecting rare circulating tumor cells

Metastasis - the development of tumor growth at a secondary site - is responsible for the majority of cancer-related deaths.

Hudsonalpha researchers help elucidate functional elements of the genome

Although the Human Genome Project sequenced a nearly-complete human genome almost 20 years ago, only about two percent of the genes in the human genome have been extensively studied and identified as protein-coding genes. Proteins form the basis of living tissues and play a central role in biological processes.

Ecological stress within freshwater species can be detected with DNA metabarcoding

DNA or eDNA, for example, river water or, as in the case of the study by the team from the University of Duisburg-Essen (Essen, Germany) within the German Barcode of Life project (GBOL II): Vera Zizka, Dr Martina Weiss and Prof Florian Leese, from individuals in bulk samples.
