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).

Study identifies genetic causes of sudden unexplained deaths in children aged 1 year and older

A new study found that changes in specific genes may contribute each year to the roughly 400 sudden unexplained deaths in children (SUDC) aged 1 year and older—and separately from sudden infant death syndrome (SIDS).

New tool provides an unprecedented view of brain cell activity in a synapse

To solve the mysteries of how learning and memory occur, Johns Hopkins Medicine scientists have created a system to track millions of connections among brain cells in mice — all at the same time — when the animals' whiskers are tweaked, an indicator for learning.

Study reveals chromosome-level changes that relate to drug resistance in melanoma

Precision therapies targeting melanoma and other cancers have improved patient survival, but tumors often stop responding to drugs, and recent studies point to changes in DNA – both inside and outside chromosomes – as a driving factor in tumor genesis as well as in treatment resistance.

CRISPR-based microfluidic platform detects respiratory viruses and SARS-CoV-2 variants

Researchers in the US have developed a novel multiplexed diagnostic platform based on CRISPR-based approaches and microfluidics - enabling robust and simultaneous surveillance of multiple viruses and viral variants. Currently, the paper is available on the medRxiv* preprint server pending peer review.
