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).

Similarities and dissimilarities in immune responses and metabolism in SARS-CoV-2 and HIV-1 infections

A new study, posted to the bioRxiv* preprint server, has developed a single-cell atlas that presents the shared and distinct immune responses and metabolism following SARS-CoV-2 and HIV-1 infections.

Virus-like particles as delivery vehicles for gene-editing

Scientists deliver gene-editing proteins through the use of engineered virus-like particles, which mediated efficient base editing both in vitro and in vivo.

Researchers identify gene variant that protects against severe COVID-19

An international metastudy led by researchers at Karolinska Institutet in Sweden has identified a specific gene variant that protects against severe COVID-19 infection.

Study shows that key parts of human immunity are shared in bacteria

The human immune system, that marvel of complexity, subtlety, and sophistication, includes a billion-year-old family of proteins used by bacteria to defend themselves against viruses, scientists at Dana-Farber Cancer Institute and in Israel have discovered.

Faster and more affordable method for detecting adulteration of meat products

Meat and sausage products can be found on the shelves of every grocery store. Although sometimes not everything that the manufacturer listed on the package is true. Expensive types of meat, such as beef, are often substituted with cheaper poultry.

Study finds blunted cortisol profiles in women who experienced childhood sexual abuse

Childhood sexual abuse can lead to depression, anxiety, cardiovascular disease and other health problems later in life. Not all abused children experience these problems, however, and researchers are working to understand whose health is affected and why.

New project aims to study how bacterial defenses influence the spread of mobile genetic elements

A major new project will investigate how bacterial defenses influence the spread of segments of DNA called mobile genetic elements (MGEs) between bacteria.

Defective gene in blood cancers could be treated with already available drugs

A defective gene, normally found in blood cancers, could be treated with drugs already available for cancers with similar gene defects, scientists at Queen’s University Belfast and the University of Birmingham have revealed.

Ultra-rapid genome sequencing technology can detect rare genetic diseases in eight hours

A new ultra-rapid genome sequencing approach developed by Stanford Medicine scientists and their collaborators was used to diagnose rare genetic diseases in an average of eight hours -; a feat that's nearly unheard of in standard clinical care.

Regrowing knee cartilage can be a promising hop toward healing joints in humans

UConn bioengineers successfully regrew cartilage in a rabbit's knee, a promising hop toward healing joints in humans, they report in the 12 January issue of Science Translational Medicine.

UCLA study provides new insights into molecular 'crosstalk' in pancreas cancer cells

Research led by scientists at the Jonsson Comprehensive Cancer Center (JCCC) at UCLA provides new insights into molecular "crosstalk" in pancreas cancer cells, identifying vulnerabilities that could provide a target for therapeutic drugs already being studied in several cancers.

AI-driven solution predicts RNA and DNA binding sites to accelerate rational drug discovery

The iMolecule group from Skoltech has developed an artificial intelligence-driven solution that uses data on the structure of RNA or DNA molecules to identify sites on them where interaction with potential drug candidates can occur.

New technique could allow more diseases to be safely treated by nanomedicine

Researchers at Penn Medicine have discovered a new, more effective method of preventing the body's own proteins from treating nanomedicines like foreign invaders, by covering the nanoparticles with a coating to suppress the immune response that dampens the therapy's effectiveness.
