Ending the latest chapter in a years-long legal battle over who invented CRISPR, the U.S. Patent and Trademark Office ruled on Monday that the revolutionary genome editing technology belongs to the Broad Institute of Harvard and MIT.

They will now have to negotiate with the Broad Institute for the right to use CRISPR for human therapies.

If there is no doctor in the house, Amazon’s Alexa will soon be able to summon one.

Amazon and telemedicine provider Teladoc Health are starting a voice-activated virtual care program that lets customers get medical help without picking up their phones.

The service, for health issues that aren’t emergencies, will be available around the clock on Amazon’s Echo devices. Customers can tell the voice assistant Alexa that they want to talk to a doctor, and that will prompt a call back on the device from a Teladoc physician.
