Ethics of gene-editing technology debated

The leading U.S. scientific organization, responding to concerns expressed by scientists and ethicists, has launched an ambitious initiative to recommend guidelines for new genetic technology that has the potential to create “designer babies.” The technology, called CRISPR-Cas9, allows scientists to edit virtually any gene ...

Widest gene study shows complex scale of obesity

The largest-ever DNA probe into obesity has thrown up scores of clues for the inherited factors behind a worsening health problem, researchers said on Wednesday. Investigators said they netted more than 100 previously-undiscovered gene variants that play a part in obesity’s complex processes. Some ...
