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).

Engineered virus-like particles power up gene editing, correcting blindness in mice

Prime editing, a versatile form of gene editing that can correct most known disease-causing genetic mutations, now has a new vehicle to deliver its machinery into cells in living animals.

Inhalable point-of-care urinary diagnostic platform for early lung cancer detection

Using a new technology developed at MIT, diagnosing lung cancer could become as easy as inhaling nanoparticle sensors and then taking a urine test that reveals whether a tumor is present.

Early-acting autophagy genes extend lifespan through alternative "garbage disposal" pathway in neurons

Autophagy, which declines with age, may hold more mysteries than researchers previously suspected. In the January 4th issue of Nature Aging, it was noted that scientists from the Buck Institute, Sanford Burnham Prebys and Rutgers University have uncovered possible novel functions for various autophagy genes, which may control different forms of disposal including misfolded proteins-;and ultimately affect aging.

New method illuminates intricate interactions of the synaptonemal complex in nematodes

We have two copies of each chromosome in every cell in our bodies except in our reproductive cells. Sperm and egg cells contain a single copy of each chromosome with a unique mix of genes from our parents, an evolutionary trick to give our offspring genetic variability.
