Human genome editing offers tantalizing possibilities – but without clear guidelines, many ethical questions still remain

Following the controversial births of the first gene-edited babies, a major focus of the Third International Summit on Human Genome Editing was responsible use of CRISPR.

‘Jurassic World’ scientists still haven’t learned that just because you can doesn’t mean you should – real-world genetic engineers can learn from the cautionary tale

As genetic engineering and DNA manipulation tools like CRISPR continue to advance, the distinction between what science ‘could’ and ‘should’ do becomes murkier.
Xenotransplantation is the transplanting of cells, tissues or organs from animals to humans. Pre-clinical trials of organ transplant from pigs have addressed some of the technical barriers. (Shutterstock)

Organ transplants from pigs: Medical miracle or pandemic in the making?

New developments in organ transplants from animals show promise. However, there has been no public engagement about a potential risk. It may streamline a pathway to humans for new zoonotic diseases.
