It’s no secret that rivers winding through major cities have been reshaped by human hands. Where wildlife and marshes once existed, gray sidewalks and bleak straight-lined tributaries have blossomed. Now, some cities are implementing floating wetlands — native plant life on a body of biodegradable materials that bobs on top of the water — to addres…

Meet the newest robotic police officer in town: the Knightscope K5. This “Robocop” completed a two month trial period in New York City’s Times Square subway station from September to November of 2023, recording video and monitoring the station. But despite city officials promising its safety, people were understandably nervous about a robotic polic…

Boredom under COVID quarantine led many to pursue some strange side hobby, but for 24 mathematicians and artists, it resulted in Mathemalchemy — a collective of mathematically (aesthetically, too) charming pieces of art — from cryptographic quilts, huge parabolas of embroidered spheres, crochet theta curves caught in fishing nets, and murals of Oct…

Oysters have been a New York City culinary staple for centuries. Hundreds of years ago, when the Indigenous Lenape people lived in the region prior to European colonization, the harbor teemed with shellfish. But by the early 20th century, pollution, urban development and overharvesting erased nearly 350 square miles of oyster beds.Fast forward to t…

When you imagine a dam, what comes to mind? Maybe it’s the hulking concrete wall of the Hoover Dam on the Colorado River or the Grand Coulee on the Columbia. Large barriers on large rivers, looming large on the horizon.But colossal structures like these make up only a fraction of the dams that chop up waterways across the United States. The nation’…

Growing up in Houston, Marina Watowich was no stranger to hurricane seasons. This familiarity now drives Watowich’s research in genomics, where she seeks to understand how the environment affects the aging process. She isn’t studying aging in humans — but in a unique population of monkeys in Puerto Rico. These monkeys live on an isolated island off…

Chimpanzees are nearing extinction in many countries. Of the four subspecies of these great apes, western chimpanzees are the most endangered. Experts estimate that their distribution is now extremely patchy, with 80% of their numbers having declined in the last 20 years. The largest-remaining population is found in the Ivory Coast in Western Afric…

Sometimes, being a “material girl” comes with a downside. An endless cycle of fashion trends doesn’t only weigh on your wallet; it takes a toll on the planet too. In 2020, the fashion industry accounted for 10% of the world’s carbon emissions, which is more than the oceanic shipping and international flight industries combined. If current practices…

Have you ever wondered how the universe will end? Chances are that the answer is “yes”; humans tend to have an innate curiosity when it comes to morbid questions.Scientists, of course, are no different. Cosmologists have pondered the ultimate fate of the universe, and many have converged on a theory: the “heat death of the universe,” also known as …

Today, many charcuterie boards, servings of buffalo chicken and cobb salads feature blue cheese and possibly even a glass of beer. New evidence shows that humans’ taste for a cheese flavored by fungi may have begun as early as 800 B.C.The Hallstatt salt mines in the Eastern Alps preserved excrement left behind by the workers who extracted salt from…

If you’re a parent, you might have the opinion that video games are a waste of time. But the U.S. Department of State, educators and other experts think that gaming might actually be the best way to engage students — especially during the isolation of the COVID-19 pandemic — on important issues, like where the food we eat comes from and how agricul…

Right in the heart of New York City is the East River, separating Manhattan and the Bronx from Brooklyn, Queens and the suburbia of Long Island. For many New Yorkers, the river is just water running under the many bridges they cross over during their daily commute. But before the confluence of the Hudson River and the harbor became New York City, t…

In the last few decades, the study of exoplanets — planets outside our solar system — has exploded. Since the first one was spotted in 1992, scientists have found thousands of different exoplanets in their own unique systems, each of which has told us something new about the cosmos.Hidden among planets made of diamond and systems that we didn’t thi…

Last year, plenty of people took up the new hobby of baking sourdough. What better to do when you can’t leave the house? And, since sourdoughs are based on cultivating a microbial community of yeast and bacteria in what’s called a “starter,” these bakers had to learn how to care for the billions of microbes with which they now shared a kitchen.But …

In the 1980s, Mark Temple was the drummer for the indie pop band The Hummingbirds. He toured the world and saw his music played on MTV, but eventually left the band and returned to school. When the university where he teaches shut down earlier this year, Temple used his time at home to rekindle his pastime: He turned the coronavirus genome into mus…

As long as humans have been around, we’ve relied on plants for our survival: as food, fuel, shelter, medicine — and to produce the oxygen we breathe. Ethnobotanists are scientists who study and catalog these complex interactions between people and plants. Yet ethnobotany has a complicated history of its own, with roots in European colonial expediti…

2020 was another record-breaking year of storms and wildfires in the United States.

Can you be a pro at isolation? If anyone could be, it seems like it would be Garrett Fondoules. Normally, he travels across the Appalachian Trail, working to map its landmarks and boundaries. Sometimes, he scarcely sees another human face. Wouldn’t a little more isolation be nothing new? Yet like everyone, Fondoules’ life has been upended by the CO…

As artists harness the powers of technology for their art, several essential questions arise. What does it mean to create art with artificial intelligence? Are these techniques truly new? And why do we even need art that uses algorithms? This seven-minute episode will explore these questions, among others.…

Think about a song you like. Regardless of the genre, the song probably includes either reverberation, distortion or both. These add texture to the music that we tend to crave. But how do they work? As a guitar player, I thought I knew. But I’d never taken a pause to think about the details. To find out what exactly reverberation and distortion are…

Perhaps you were woken up today by the calls of a singing bird — perhaps trying to mate, or simply to communicate. In an Anthropocene world, those birdsongs are changing. Songbirds today, many of whom live in the midst of human cities, are singing into increasingly noisy skies. Their songs must compete with the din of planes, trains, and automobile…

We all know smoking is bad for your health. So is second-hand smoke. It turns out, even a leftover cigarette butt could be bad for you as well. Most butts are made with plastic and are not biodegradable. Scientists know nicotine and other toxins leach out of these ubiquitous plastic waste products, but recent research shows they could expose us to …

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 p…

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 spee…

PODCAST: Cooking up Conservation byOleh Scienceline

It’s a bird! It’s a plane? No, wait, you can hear that it’s a bird. Tracking bird migration can be tricky, especially in a dark sky. But when individual species of birds talk with each other through flight calls, researchers can listen in to determine exactly what species are flying overhead. And now, researchers are developing a computer system — …

Prescription drugs seep from Manhattan into the Hudson River, where they can wreak havoc on unsuspecting fish.
