Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

This is Scientific American's 60-second science. I'm Christopher in Taliatta.

Think killer robots. What comes to mind? Maybe this guy?

I'll be back.

We are not talking about Terminator. We're talking about much simpler technologies that are best a few years away.

In fact, many of which you can see under development today

in every theater of the war.

Toby Walsh, a professor of artificial intelligence at the University of New South Wales in Sydney.

He spoke February 14th as part of a discussion called Killer Robots, Technological, Legal,

and Ethical Challenges at a meeting of the American Association for the Advancement of Science.

And so these are systems that are using sensors and software processing on their own to determine

what constitutes a target and then applying lethal force to that without supervision or meaningful human

control. Another speaker, Peter Asero, co-founder of the International Committee for Robot Arms

Control, has participated in UN talks on autonomous weapons.

So what we've really been lobbying is not a sort of complete ban on some specific technical

capability, but a more general requirement that all weapons systems should have meaningful

human control over the targeting and engagement of those weapons systems.

We're also quite fearful that these could constitute a new kind of weapon of mass destruction
