A study in the journal Nature explains how age reshapes the blood system. In both humans and mice, a few stem cells, or ...

Each cell in a plant, animal, or person contains millions, or even billions, of DNA base pairs—molecules ... In order to chart human migration patterns, investigate animal domestication, and ...

Zooming in on individual cells The body has various mechanisms to repair DNA, but the process can differ from cell to cell. This makes it important to study DNA repair in individual cells.

BALLSTON SPA – The trial of Ronald Rayher continues into its second week in Saratoga County Court where witnesses have ...

What kinds of DNA can be used to profile a potential killer? DNA is present in every single cell in the body, and it can be deposited at a crime scene in a number of different ways, including ...

Loss-of-function variants in genes encoding tumor suppressor proteins, such as those that mediate DNA repair and cell-cycle checkpoints, can also contribute to an unstable genome. A gene that ...

"This work is a milestone in the application of DNA nanotechnology to regulate cell behavior," Liu says. The team works with giant unilamellar vesicles (GUVs), which are simple, cell-sized ...

A study explains how age reshapes the blood system. In both humans and mice, a few stem cells out-compete their neighbors and gradually take over blood production. The loss of diversity results in a ...
