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).

Healthy, cancer, and immunosuppressed patients all benefit from COVID boosters

In a recent study posted to the medRxiv* pre-print server, researchers developed a mechanistic mathematical model to predict the course of vaccine-induced immunity in healthy and immunosuppressed patients for the long term, exceeding the time frames for which clinical data is currently available.

Transcriptomic data reveals the evolutionary relationships of two groups of ancient invertebrates

Kamptozoa and Bryozoa are two phyla of small aquatic invertebrates. They are related to snails and clams (collectively called mollusks), bristleworms, earthworms, and leeches (collectively called annelids), and ribbon worms (nemertea).

New, safer CRISPR approach may help correct genetic defects in the future

Curing debilitating genetic diseases is one of the great challenges of modern medicine. During the past decade, development of CRISPR technologies and advancements in genetics research brought new hope for patients and their families, although the safety of these new methods is still of significant concern.
