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).

Novel technique to study gene splicing reveals new insights into the process

Genes are like instructions, but with options for building more than one thing. Daniel Larson, senior investigator at the National Cancer Institute, studies this gene "splicing" process, which happens in normal cells and goes awry in blood cancers like leukemia.

Dormancy emerges as a natural evolutionary response to over-predation, study finds

Why do predators sometimes lay dormant eggs -- eggs which are hardy, but take a long time to hatch, and are expensive to produce?

Generating genomes and encoding new abilities into artificial DNA

A new study to be presented at the American Association for the Advancement of Science (AAAS) in February 2020 will report on the generation of the world’s first artificially created bacterial genome using a digital design algorithm along with the synthesis of DNA building blocks on a large scale. This genome takes form by chemical rather than template-based synthesis. The research is published in the journal Proceedings of the National Academy of Sciences.

Stress in kids could have long term genetic consequences finds study

Researchers have found that being separated from parents at a young age could lead to a rise in stress hormones, which could have direct consequences on altering the genetic makeup of the child, which can then be passed on to the future generations. The study titled, "Childcare outside the family for the under-threes: cause for concern?" was published in the latest issue of the Journal of the Royal Society of Medicine.

Scientists pinpoint protein that plays key role in lung cancer and melanoma progression

Scientists from Far Eastern Federal University, University of Geneva (Switzerland), Minjiang University, and Fuzhou University (China) pointed out WDR74 protein playing an important role in lung cancer and melanoma primary tumors/metastases progression.

Scientists unravel mechanisms that lead to ventricular enlargement in schizophrenia

Enlarged cerebral ventricles are found in 80% of individuals with schizophrenia, yet the mechanisms that lead to ventricular enlargement are mostly unknown.

Study provides a detailed molecular snapshot of endometrial cancer

A study published Feb. 13 in Cell provides an unprecedented look at the dozens of molecular steps that occur to bring about endometrial cancer, commonly known as uterine cancer.

Scientists isolate individual cells that cause autoimmune disease

Researchers have homed in on the cells that cause an autoimmune disease to arise in the body. The study, published in the journal Cell in February 2020, as part of the far-seeing Hope Research project, reports on the discovery.

Treating soft tissue sarcoma with shorter radiation treatment found to be safe, effective

A new study led by researchers at the UCLA Jonsson Comprehensive Cancer Center found that treating soft tissue sarcoma with radiation over a significantly shorter period of time is safe, and likely just as effective, as a much longer conventional course of treatment.

Improving ability to predict autism risk with few drops of blood

Within days of birth, a few drops of blood are collected from every newborn in California--and across the United States -- which are then stored on filter paper and screened for dozens of genetic and congenital disorders, such as phenylketonuria, an inherited metabolic disorder that can result in intellectual disability, seizures, heart and behavioral problems.

Unusually large, bacteria-killing viruses discovered

Scientists have discovered hundreds of unusually large, bacteria-killing viruses with capabilities normally associated with living organisms.

Molecular study defines the contributions of key genes, proteins to endometrial cancer

The most comprehensive molecular study of endometrial cancer to date has further defined the contributions of key genes and proteins to the disease, say its authors.

New method to measure mutations in father's sperm may reveal ASD risk in future children

While the causes of autism spectrum disorder are not fully understood, researchers believe both genetics and environment play a role.

Marine bacteria genes can help track environmental changes caused by humans

The gene expression of marine bacteria can be a valuable sensor for discovering environmental changes caused by humans. Furthermore, bacteria help to clean our oceans and hopefully they could be used to purify drinking water from harmful environmental toxins in the future.

Study tests hypothesis that empty SV40 capsids would improve sepsis outcomes

Numerous previous attempts to develop therapeutic treatments, directed at discreet targets of the sepsis cascade, could not cope with the complex pathophysiology of sepsis and failed.

Minigenes produced by CRISPR combat liver disease in mice

A new gene-editing technique based on CRISPR was used to successfully avoid the development of a liver disease that can be caused by hundreds of mutations, as well as to ease the symptoms in mice. This proof-of-concept study was published online in the journal Science Advances in February 2020.

Newly discovered large phages blur the life/non-life boundary

A new study published in the journal Nature shows that there are literally hundreds of viruses large enough to consume bacteria, and with properties that are typical of a living organism rather than the non-living self-replicating packages of DNA/RNA that viruses are often assumed to be.
