Researchers pioneer new method to edit genes in human cells

Over the past decade, the CRISPR genome-editing system has revolutionized molecular biology, giving scientists the ability to alter genes inside living cells for research or medical applications. Now, researchers at Gladstone ...

Genes are switched on in the human embryo from the get-go

The finding that some genes are active from the get-go challenges the textbook view that genes don't become active in human embryos until they are made up of four-to-eight cells, two or three days after fertilization.

New prime editing system inserts entire genes in human cells

Researchers at the Broad Institute of MIT and Harvard have developed a new version of prime editing that can install or swap out gene-sized DNA sequences. First developed in 2019, prime editing is a precise method of making ...

Anthrax arms race helped Europeans evolve against disease

New research from the Cornell College of Veterinary Medicine has revealed how humans evolved greater resistance against anthrax multiple times during history: when they developed a diet of more ruminants, and when agricultural ...

How to turn specific genes on and off

All the cells in an individual's body bear the same genetic code. It is the reading and writing of this code—the "turning on" and "turning off" of specific genes in specific cells—that gives the cells their identities. ...

The vast little library inside your cells

The human genome can be thought of as a massive library, containing over 20,000 different "instruction manuals": your genes. For example, there are genes which contain information to build a brain cell, a skin cell, a white ...
