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).

Education and employment experiences in early adulthood play a role in later life cardiovascular health

New research published today in the Journal of Epidemiology and Community Health has found that education and employment experiences in early adulthood contribute to cardiovascular health inequalities in later life, independent of occupation and family income in mid-adulthood.

Research reveals a microRNA network as putative mediators of myocardial reductive stress

Last year, University of Alabama at Birmingham researchers reported that reductive stress - an imbalance in the normal oxidation/reduction homeostasis - caused pathological changes associated with heart failure in a mouse model.

New study offers insight into how high-risk form of blood cancer can develop in children

In some children with acute myeloid leukemia, cancer cells have the same amount of DNA changes as healthy blood stem cells.

DNA recovered from illicit drug capsules could be used to track down criminal syndicates

Forensic scientists have for the first time shown that DNA can be recovered from the surface of capsules after just 15 seconds of contact by drug manufacturers & dealers – making it possible for law enforcement agencies to track down criminal syndicates around the world.

Using circulating tumor DNA to detect urothelial cancer relapse could help improve treatment

Using circulating tumor DNA to identify patients at risk of urothelial cancer relapse after surgical resection could help improve post-surgery treatment.

Researchers develop the most comprehensive molecular map of lung squamous cell carcinoma

Lung cancer remains the leading cause of cancer-associated death in the United States and worldwide. Patients with a subtype called lung adenocarcinoma (LUAD) have benefited from the development of new targeted medicines, but the search for effective new therapies for another subtype called lung squamous cell carcinoma (LSCC) has largely come up short.

Postpartum sleep deprivation associated with accelerated biological aging

When new mothers complain that all those sleepless nights caring for their newborns are taking years off their life, they just might be right, UCLA research published this summer in the journal Sleep Health suggests.

New DNA writing technique can precisely and efficiently edit bacterial genomes

Biological engineers at MIT have devised a new way to efficiently edit bacterial genomes and program memories into bacterial cells by rewriting their DNA.

Vaccinia-based COVID-19 vaccines confer immunity in hamster model

In a paper recently uploaded to the preprint server bioRxiv* by Kulkarni et al. (August 3, 2021), the potential of vaccinia virus-based vaccines expressing the full-length SARS-CoV-2 spike protein is examined in mice and Syrian hamsters. The findings report that the vaccine generates high titers of neutralizing antibodies with good activity towards SARS-CoV-2 variants of concern.

Study investigates the role of eIF4A3 protein in the growth of cancer cells

For a cell to grow and divide, it needs to produce new proteins. This also applies to cancer cells. In a new study published today in Science Advances, researchers at Karolinska Institutet in Sweden have investigated the protein eIF4A3 and its role in the growth of cancer cells.
