Although Cas9 has been the go-to enzyme for gene-editing, that doesn’t mean it’s necessarily the best option. Now a team of scientists, including the co-creator of CRISPR, has engineered a more precise enzyme, known as Cas12b.

Preliminary results of an investigation by the Chinese government into the ethics of experiments that led to the birth of the world's first gene-edited babies have now been released. The report condemns the actions of He and confirming some of the questions previously raised about this strange case.

Alongside new discoveries in gut-brain communication and the genesis of Alzheimer’s disease, the FDA advanced acceptance of psychedelic medicines, from psilocybin to marijuana. But looming over all of these milestones was the controversial alleged birth of the world’s first gene-edited baby.

Classical swine fever virus (CSFV) is a highly infectious and deadly disease among pigs, with outbreaks leading to huge livestock losses. Now, researchers from Jilin University in China have genetically modified pigs to be resistant to the virus, which will also pass that down to their offspring.

An exciting new study has demonstrated how a new kind of CRISPR technique can increase the expression of certain genes, instead of the more traditional approach of cutting or editing DNA. The method was tested in mice, targeting genes associated with hunger, and stopped the animals becoming obese.

The world’s first gene-edited human babies have been born in China. Professor Jiankui He claims that by removing a specific gene from the embryos using CRISPR-Cas9, the twin girls would have a natural immunity to HIV. But scientists question the safety, effectiveness and morality of the procedure.

In a remarkable proof-of-concept study, scientists from the University of Pennsylvania and the Children’s Hospital of Philadelphia have, for the first time, successfully used CRISPR gene-editing technology on mice in utero, to prevent the animals being born with a lethal metabolic disorder.
