As the world faces unprecedented climate disasters — from the months-long bushfires in Australia to the rapidly melting ice-sheets of Greenland and Antarctica — teams of scientists from around the globe are busying themselves to come up with new climate solutions.

Climate change could soon leave a bad taste in your mouth.

Scientists expect climate change will make storms more intense, so the city must amp up its defenses

Shells, often overlooked on the sea shores, tell professor Geerat Vermeij a story about evolution that spans millions of years. Vermeij, a leading geologist and creator of the famous escalation theory, has been captivated by shells since a young age. His is the story of pursuit of passion despite an obstacle that might deter others. You see, professor Vermeij is blind.

Listen to his inspiring story of beauty and undeterred curiosity about the world around us.

Despite perceptions that the Hudson is not fit for swimming, it is perfectly safe in many places. But how do you know where?

In the midst of the coronavirus pandemic, Maria Paula Rubiano started wondering about how personal space boundaries differ across cultures. She followed that curiosity, and here’s what she found.

Earlier this year, the world learned that Barbara Streisand had cloned her beloved pet dog, Samantha. As a news item, it was a weird novelty that got a fair amount of attention. But I wanted to know: How exactly do you clone a dog? In this podcast, I dug into the science of cloning to figure it out. Along the way, I learned a bit about why people clone their pets and what parts of the cloning process can get a little hairy.

In the far reaches of the South Pacific lies the country of Vanuatu, a small cluster of islands about 1600 miles east of Australia. This hard-to-reach archipelago covers an area smaller than the size of Hawaii. Despite its minute size, the islands are immensely diverse. The country has one of the highest language densities in the world (112 to be precise) and its forests are teeming with a rich array of local plant life. Vanuatu’s plant diversity has never been fully recorded, however, and the country’s rapid industrialization is putting local plant knowledge at risk. So, for the past five years, a team of researchers led by the New York Botanical Gardens has been working on a project to document the country’s plants, their names in local dialects and their indigenous uses. The researchers are finding that Vanuatu’s plant diversity and language diversity are intricately linked. In this podcast, I speak to Gregory Plunkett, a researcher from the New York Botanical Gardens who is one of the project’s leaders, and Frazer Alo, a forestry student from Vanuatu who has been helping with their field work.

Whether it takes place onstage, at karaoke, or in the shower, singing is a special activity unique from speech. And since it uses a lot of the same machinery (mouth, tongue, voice box, etc.), at least some of that difference must lie in the brain. This podcast looks at the mental phenomenon of song from both sides. Bernadine Gagnon, a Columbia speech therapist, explains how singing can sometimes help stroke victims re-learn to speak, and Kalman Katlowitz, a NYU neuroscientist, talks about his lab’s attempt to locate part of the brain’s singing circuit.
