Anthropologist Helen Fisher has long been trying to answer the question: why do you fall in love with one person rather than another? Her research says we've evolved four basic styles of thinking and behaving linked with the dopamine, serotonin, testosterone, and estrogen systems. Fisher used that research to create a questionnaire that's been taken by 15 million people in 40 countries, shedding light on how we choose our mates.

She's also one of the experts behind the Singles in America survey from Match.com, the most recent of which shows that people are using AI in online dating, and are increasingly trying alternatives to monogamy.

It's harder than ever to define what it means to be evangelical in America. But one constant? The Trump support.

She tells Niala why white Evangelical power is stronger than ever for Republicans in 2024.

Misty Copeland is the rare ballerina who's recognizable well beyond the world of ballet. In 2015, she became the first Black woman to reach the title of principal dancer with the prestigious American Ballet Theatre. Throughout her career, Misty has spoken out about being one of the few Black dancers on the professional stage, and why early and equal access to the arts is so important. Through her foundation, she’s trying to connect more young people to ballet through after-school programs.

Niala Boodhoo spoke to Misty this week about forging new paths in an old art form, and why that matters for equity and inclusion beyond the stage.

"As a passionate Muslim and a passionate Jew, we have come together to humbly share a path forward for how to transcend the construct of 'us vs. them' and side with humanity instead." That's from a recent open letter to college students across America, written by Daniel Lubetzky, founder of KIND Snacks, and Lonnie Ali, co-founder of the Muhammad Ali Center and wife of the late Muhammad Ali.

Lonnie and Daniel have both witnessed the growing hatred on American college campuses as the Israel-Hamas war rages on, and they say students themselves are at the heart of the solution. In their letter, they detail what they call ten ways to side with humanity, including: "It helps, not hurts, your cause to empathize with the pain of the other side" and "to get the full story, pop your social media bubble."

• Plus: the new challenges for DEI programs on college campuses.

Guests: Daniel Lubetzky, founder of KIND Snacks and co-founder of the Starts with Us movement; Lonnie Ali, co-founder of the Muhammad Ali Center, and wife of the late Muhammad Ali.

Extreme weather is being increasingly linked to climate change, thanks to the work of scientists the world over. But Dr. Fredi Otto's contribution is unique: she is getting it done faster. That hurricane, that drought, that wildfire? Her team at World Weather Attribution can say the extent to which climate change was a factor, but within weeks, not years.

In other words, she leads the world's only rapid reaction force of climate scientists. Why she says linking extreme weather events to climate change matters more than ever.

Guests: Dr. Fredi Otto, co-founder of World Weather Attribution, and a Senior Lecturer in Climate Science at Imperial College London
