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).

Novel testing method could simplify widespread tuberculosis screening

Tuberculosis can be tough to detect. Diagnosis usually requires coughing up a sputum sample from the lungs, which can be unpleasant, impractical, and even hazardous.

Poll shows high interest, uneven use of direct-to-consumer medical tests

Kitchen counters and bathroom sinks across America turned into miniature medical testing labs over the past year, as millions of people swabbed their noses and found out in minutes if they had COVID-19.

Novel method deploys nanopore tweezers to facilitate inhibition of SARS-CoV-2 helicase at single-nucleotide resolution

In a new study, researchers visualized the mechanism of action and inhibition of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) non-structural protein 13 (NSP13) at high spatio-temporal resolution.

Cell-free DNA circulating in the blood may signal early signs of dementia and frailty

In a long-term prospective study of more than 600 older participants, Johns Hopkins Medicine researchers say they have evidence that higher levels of cell-free DNA circulating in the blood may signal increased risk of chronic inflammation associated with early signs of frailty and dementia.

Light-Seq technology for barcoding and deep-sequencing selected cell populations in tissues

Under the microscope, researchers often observe different cell types organizing themselves in peculiar patterns within tissues, or sometimes a rare cell type that stands out by occupying a unique position, exhibiting an unusual shape, or expressing a specific biomarker molecule.
