First monkeys cloned with technique that made Dolly the sheep

Biologists in Shanghai, China, have created the first primates cloned with a technique similar to the one used to clone Dolly the sheep and nearly two dozen other species. The method has failed to produce live primates until now. Cloned animals offer some significant advantages over non-clones as models for studying human disease.

AI-controlled brain implants for mood disorders tested in people

Nature:  Brain implants that deliver electrical pulses tuned to a person’s feelings and behaviour are being tested in people for the first time. Two teams funded by the US military’s research arm, the Defense Advanced Research Projects Agency (DARPA), have begun preliminary trials of ‘closed-loop’ brain implants that use algorithms to detect patterns associated with mood disorders. These devices can shock the brain back to a healthy state without input from a physician.

A Visual Guide to the New Blood Pressure Guidelines

MedPage Today: The American College of Cardiology and American Heart Association's new blood pressure guidelines came in a comprehensive, and thus ponderous, 192-page document.

Yes, you are being watched

The US Food and Drug Administration has approved an antipsychotic pill embedded with a sensor that tracks when a person swallows it. But some question the whether a drug used to treat schizophrenia is well-suited to an innovation that monitors behaviour and sends signals to doctors. “There’s an irony in it being given to people with mental disorders that can include delusions. It’s like a biomedical Big Brother,” says psychiatrist Jeffrey Lieberman.

First-ever gene editing in a human body

A person with a metabolic disease called Hunter syndrome has received the first ever in vivo gene-editing therapy. If successful, the treatment will permanently change his DNA and cure the disease.

 

Read Nature’s primer on the new wave of gene-editing therapies (from 2015).
