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 method helps identify rare genetic disease that affects brain development

Rare disease experts detail the first results of an unprecedented collaboration to diagnose people living with unsolved cases of rare diseases across Europe.

Researchers discover a new and unique form of ALS

In a study of 11 medical-mystery patients, an international team of researchers led by scientists at the National Institutes of Health and the Uniformed Services University discovered a new and unique form of amyotrophic lateral sclerosis (ALS).

Could a mathematical application of information theory identify and predict SARS-CoV-2 mutations?

An interesting new study by researchers at the University of Portsmouth, UK, describes the use of a mathematical method to sequence genomes based on information theory. The method offers an alternative to clinical techniques, allowing mutations to be detected and possibly even predicted. In this way, it opens new research opportunities in bioinformatics and genetics.

Study could help identify risk of secondary leukaemia in certain children

Scientists from the Wellcome Sanger Institute and the University of Cambridge found that in children with neuroblastoma - a cancer of immature nerve cells - treatment with platinum chemotherapy caused changes to the genome that could then cause leukaemia in some children later on.

Harnessing DNA’s properties to craft “‘topologically tunable” DNA-based materials

While DNA is often idealized as the "molecule of life", it is also a highly sophisticated polymer that can be used for next-generation materials. Beyond the fact that it can store information, further fascinating aspects of DNA are its geometric and topological properties, such as knotting and super-coiling.

New biomarker could be used to determine resistance of ovarian cancer to platinum chemotherapy

Epithelial ovarian cancer (EOC) is the most common lethal gynaecological cancer. Ovarian cancer is usually treated with platinum-based chemotherapy; however, a significant number of patients are resistant to such treatments and relapse soon afterwards.
