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).

Rapid DNA sequencing technique used to diagnose rare genetic disease in short time

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.

Topical antiseptic Acriflavine inhibits SARS-CoV-2 and other betacoronaviruses

A new study, published in the journal Cell Chemical Biology, has reported the discovery of acriflavine (ACF), an effective inhibitor of SARS-CoV-2. This drug is a mixture of trypaflavines (3,6-diamino-10-methylacridinium chloride and 3,6-diamino-3-methylacridinium chloride) and proflavine (3,6-diaminoacridine).
