Genetic engineering, also known as genetic modification, is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to ...

The return of the long-extinct wooly mammoth or dodo bird may sound like a storyline straight out of science fiction. It’s not. Several de-extinction projects all share an ambitious aim to resurrect ...

Changing an organism’s genome is a profound act, and the tools you use to make the changes don’t alleviate the need for responsible regulation. Unlike “traditional” genetically modified organisms (GMO ...

Biotech meets livestock: CRISPR and genomic tools are enabling traits like disease resistance, faster growth, and better feed efficiency in cattle, sheep, and other farm animals. Ethics under ...

When scientist J. Craig Venter and his team announced in 2010 that they had created the first cell controlled by a fully synthetic genome, it marked a turning point in how scientists think about life.

Maxine Singer, a molecular biologist who helped map the inner workings of DNA and led seminal debates in the 1970s that contributed to the first guidelines on the potential risks and ethical ...

The modification of the genetic makeup of cells. Genetic engineering modifies the DNA in cells to alter their behavior. In 1953, the discovery of the DNA double helix, technically deoxyribonucleic ...

In recent years, the U.S. Food and Drug Administration has approved more than a dozen gene-editing and cell-based therapies. We are now in the second great wave of the genetic revolution, not defined ...

Collaborative research defines a novel approach to understanding how certain proteins called transcription factors determine which genetic programs will drive cell growth and maturation. The method, ...

Modifying the organ instead of the recipient isn’t a new idea, but it is an important one, said Jeffrey Platt, a transplantation biologist at the University of Michigan Medical School who was not ...
