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 ...

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 ...

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 ...

Genetic engineering is moving from the lab bench into clinics, farms, and even family planning decisions, promising to change how we prevent disease, age, and define human potential. The same tools ...

These mutations improve biocontainment, transformation stability, and overall performance in genetic engineering of plants. Complementing the strains, researchers also developed new plasmids and a ...

At a meeting of top conservation groups this week, a bioethics question took center stage: Should scientists be allowed to tinker with the genes of wild plants and animals? Subscribe to read this ...

For nearly a decade, Jared Westbrook has worked on resurrecting the American chestnut, an iconic tree that nearly vanished from the United States a century ago. The American Chestnut Foundation, a ...

Gene editing is now reaching the mainstream, ushering in a new era of genetic manipulation. Traditionally, inserting or deleting entire genes, regulating their expression, and altering specific ...

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 ...

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 ...
