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 Shows How Genetic Variations Can Enhance Cancer Drug Effectiveness

By exploiting the genetic variation in cancer cells, an already approved cancer drug demonstrated enhanced effects against cancer cells in specific patient groups.

New Understanding of the Evolution of Multicellular Life

In 2017, the single-celled species Chromosphaera perkinsii was found in maritime sediments in Hawaii. More than a billion years ago, long before the first animals appeared on Earth, the earliest indications of its existence were found.

Unraveling the Spatial Complexity of Gene Expression with Seq-Scope

A new method, developed by University of Michigan researchers, creates images that are worth many gigabytes of data, which could revolutionize the way biologists study gene expression. Seq-Scope, developed by Jun Hee Lee, Ph.D., Hyun Min Kang, Ph.D., and their colleagues, was first described in Cell in 2021 as the first method to analyze gene expression at sub micrometer-scale spatial resolution.

F-Actin Accumulation Impairs Brain Function in Aging Fruit Flies

Humans aren't the only ones who grow forgetful as they age -; fruit flies do, too. But because fruit flies have a lifespan of only about two months, they can be a useful model for understanding the cognitive decline that comes with aging.
