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 plasmofluidic chip could accelerate diagnosis during current and future pandemics

Reverse transcription-polymerase chain reaction (RT-PCR) has been the gold standard for diagnosis during the COVID-19 pandemic.

Genomic study can reveal adaptive mechanisms of life under future ocean acidification

Human-driven global change is challenging the scientific community to understand how marine species might adapt to predicted environmental conditions in the near-future (e.g. hypoxia, ocean warming, and ocean acidification).

New software tool detects, evaluates, and quantifies off-target editing activity

CRISPR technology enables researchers to edit genomes by modifying DNA sequences and hence gene function.

Two components of bacterial CRISPR-Cas immunity system are physically linked

Skoltech scientists have demonstrated that the two components of the bacterial CRISPR-Cas immunity system are physically connected.

Genetic and molecular mechanisms make chemotherapy drug work for some cancer patients

The chemotherapy drug decitabine is commonly used to treat patients with blood cancers, but its response rate is somewhat low. Researchers have now identified why this is the case, opening the door to more personalized cancer therapies for those with these types of cancers, and perhaps further afield.

New method helps tests large groups for SARS-CoV-2 infection

Researchers at the Vienna BioCenter designed a testing protocol for SARS-CoV-2 that can process tens of thousands of samples in less than 48 hours. The method, called SARSeq, is published in the journal Nature Communications and could be adapted to many more pathogens.

Telomere length decreases most rapidly from birth to age 3, shows study

Telomeres are protective caps on DNA that shorten as we grow older. Now, one of the first studies to examine telomere length (TL) in childhood finds that the initial setting of TL during prenatal development and in the first years of life may determine one's TL throughout childhood and potentially even into adulthood or older age.

Environmental DNA helps track down species on the move

Many individuals would like to prevent sloughed-off skin and bodily fluids. However, for marine biologists like Cheryl Lewis Ames, Associate Professor of Applied Marine Biology in the Graduate School of Agricultural Science at Tohoku University (Japan), such life remnants have become a magical guide to detecting the unseen.

Exposure to chemicals in plastic during the fetal stage is linked with a lower IQ

Bisphenol F chemical (found in plastics) may cause changes in a gene that is crucial for neurological development. Researchers from the Swedish universities of Uppsala and Karlstad made this discovery.

Study identifies predictive causal role for specific cell types in type 1 diabetes

Researchers revealed a predicted causative role for certain cell types in type 1 diabetes by examining its genetic foundations.

Study shows that higher treeless areas are home to far more species

Normally, mountain forests are among the most diverse habitats in alpine regions. Yet, as a team from the Alfred Wegener Institute discovered in the Tibetan Plateau, the higher, treeless areas are home to far more species.

Study shows that Bubonic Plague had a long-term impact on immune gene expression

A new study shows that the Bubonic Plague has had a long-term impact on immune gene expression.

Study identifies DNA alterations that underpin brain and cognitive decline in the elderly

According to a new mathematical model published recently in eLife, Alzheimer’s disease has some important similarities with healthy aging.

Wild relatives of modern peanut plants can withstand diseases

The wild relatives of modern peanut plants have the ability to withstand disease in ways that peanut plants can't. The genetic diversity of these wild relatives means that they can shrug off the diseases that kill farmers' peanut crops, but they also produce tiny nuts that are difficult to harvest because they burrow deep in the soil.

Successful class of therapeutics attack and shut down unique and harmful genes

A potential class of therapeutics that uses synthetic nucleic acids to attack and shut down harmful genes while preventing viral spread is gathering momentum.

Exposure to even low levels of lead can trigger epigenetic changes

A research team from Brazil and Portugal has identified a link between a microRNA (miRNA) and the presence of lead in an organism.

Refreshers develop new DNA sequencing method

An international research team headed by Michal Hocek of the Institute of Organic Chemistry and Biochemistry of the Czech Academy of Sciences (IOCB Prague) and Charles University and Ciara K. O'Sullivan of Universitat Rovira i Virgili (URV) in Spain have developed a novel method for labeling DNA, which in the future can be used for sequencing DNA by means of electrochemical detection.
