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.

Social media platforms like Facebook use a combination of artificial intelligence and human moderators

to scout out and eliminate hate speech.

But now researchers have developed a new AI tool that wouldn't just scrub hate speech,

but it would actually craft responses to it, like this.

The language used is highly offensive. All ethnicities and social groups deserve tolerance.

And this type of intervention response can hopefully short-circass the hate cycles that we often get in these different forums.

Anna Bethke, a data scientist at Intel. The idea she says is to fight hate speech with more speech,

an approach advocated by the ACLU and the UN High Commissioner for Human Rights.

So with her colleagues at UC Santa Barbara,

Bethke got access to more than 5,000 conversations from the site Reddit,

and nearly 12,000 more from Gab,

a social media site where many users banned

by Twitter tend to resurface. The researchers had real people craft sample responses to the hate speech

in those Reddit and Gab conversations. Then they let natural language processing algorithms

learn from the real human responses and craft their own, such as...

I don't think using words that are sexist in nature contribute to a productive conversation.
