Foghorn honks helped duckbills set the mood

Unlike the roars in movies, dinosaurs likely cooed, rumbled, and boomed

Fossil evidence and CT scans suggest that many dinosaurs produced low-frequency sounds using resonating crests, closed-mouth vocalizations, or organs similar to those of birds and crocodiles. Larger sounds would not have been helpful for sneakily hunting prey.

Some animals possess sensitive hearing to help pinpoint prey and map the world

Bats and dolphins produce sound to reflect off surfaces and create a mental image of their surroundings. Owls' faces are dish-shaped to help funnel sounds to their ears, including that of mice moving along leaves or snow. Pinnipeds, such as seals and walruses, hear in both air and water.

Listen to recordings of different fish species

Scientists have captured and curated this collection of species-specific recordings, helping us gain a deeper understanding of underwater ecosystems. Uncover their sounds, which include a lot of thumps, burps, and grunts.

Why parrots can talk like humans

Birds are built with incredibly versatile tracheas that can mimic all kinds of sounds from their environment. For parrots, that includes human speech. This brief video explains why birds, who have such distinct anatomies from humans, are somehow able to talk like them, anyway.

Herd behavior has been seen in 193-million-year-old dinosaur fossils

Scientists excavated eggs, juveniles, and adult remains in Patagonia, all arranged by age group. The organization into structured groups may have contributed to evolutionary success by consolidating eggs in one location to make defending them easier.

Fish populations in the Great Barrier Reef have increased after installing waterproof speakers on the ocean floor that played recordings of sounds from healthy coral reefs.

How birds are becoming research assistants

Through the creation of tiny sensors easily placed on their bodies, birds have served as research assistants for various scientists. With untold numbers of birds sending back data, researchers have achieved greater insights in long obscure areas of meteorology, ecology, and more. For example, weather scientists use high-flying birds to outline the height of the planetary boundary layer, while conservationists track gulls to protect migrating whales. Learn more here.

Listen to the earliest known recording of a whale song

A recording of a humpback whale was taken by scientists from the Woods Hole Oceanographic Institution near Bermuda in 1949, but forgotten for decades. When first captured, researchers didn't know what animal they were hearing, and therefore didn't catalogue the recording. The well-preserved audio was found by the team's archivist in 2025.

An Aztec skull whistle discovered in the 1990s was mistaken for a toy

In the late 1990s, archaeologists unearthed a sacrificed man clutching two skull-shaped clay whistles at a Mexico City temple to the wind god Ehecatl (eh-HEH-kahtl). Initially dismissed as toys, the instruments produce a scream-like sound that modern brain scans show triggers fear and urgency responses in listeners. This podcast explores the discovery.

The Bone Wars turned paleontology into a rivalry fraught with public scandal

Othniel Charles Marsh and Edward Drinker Cope were friends-turned-enemies competing for the glory of discovering dinosaurs. It became so intense that when Cope died, he donated his body to science to prove he had a bigger brain than Marsh.

Making sense of Mexico City's traffic honks and horns

A car's horn makes just one sound, but somehow, drivers across the world manage to use the monotone for a surprising variety of purposes. This audio-inflected essay takes readers into the nuanced horns of Mexico City's famously congested traffic, providing a "claxonomy" (taxonomy + claxones, or horns) of its drivers' honks.

The ancestors of ostriches and emus could fly

The discovery of a 56 million-year-old fossil bone helps explain how this (mostly) flightless family of birds spread to so many different continents.

Multiple species exhibit convergent evolution by developing crab-like features

Various organisms that appear to be different types of crabs, such as porcelain crabs and coconut crabs, have been shown to belong to distinct decapod lineages whose predecessors resemble shrimp or lobsters. Environmental pressures and other factors have caused these species to develop similar characteristics, which nature has shown are beneficial to survival.

In a short clip captured during a blackwater night dive in the Lembeh Strait, a blanket octopus unfolds and displays a colorful web multiple times its original size. The aquatic animal’s iridescent body and tentacles glow against the nighttime...

Porcupines, when threatened, go piloerect—essentially, they get goose bumps

If stressed, the animal appears to grow to about twice its normal size because it goes piloerect, which causes the quills to stand erect. If this intimidation tactic to avoid conflict doesn't work on the predator, the animal may get stabbed by the quills upon contact with the porcupine.

Stonehenge produces concert-hall-like acoustics

Acoustics researcher Trevor Cox discovered that Stonehenge acts like a concert hall, reflecting and amplifying sound. This video shows Cox demonstrating the effect using a scale model inside a soundproof studio.

Jeep culture, explained

Jeeps originated as all-purpose vehicles in World War II and have since become the most common off-road vehicle. Owners greet each other with a wave, but there's a pecking order. Drivers of younger, less-modified models are expected to initiate the wave to older, vintage Jeeps. Also, all those rubber ducks are tokens left on that particular Jeep from admirers.

View some of the species named after David Attenborough

Acisoma attenboroughi is a dragonfly from Madagascar named in honor of Attenborough's 90th birthday. Stating they liked watching Attenborough's documentaries with their family, the discoverer of a flightless weevil from Indonesia named it Trigonopterus attenboroughi in 2014. A Peruvian frog was named Prisimantis attenboroughi in 2014 to honor Attenborough for raising awareness of wildlife conservation.

Articulating weird memes

Some memes eschew established formats and references, creating new variants that resonate with scrollers through strange meta-jokes or compositions. This episode of this podcast, geared toward blind netizens, dives into some of the weird memes being shared online, such as one in which a pigeon sitting on a shoddy excuse for a nest, single egg forgotten, is meant to inspire comfort in those whose efforts have fallen short.

Some female fireflies mimic the signals of other species to lure in and eat them

The genus Photuris does not produce its own defensive pheromones to ward off predators, so it has developed mimicry to attract males of firefly species that do. Unsuspecting males are consumed after these chemicals—lucibufagins—are extracted.

O'Connor raised 40 peacocks, which became symbols for her fiction

O'Connor was drawn to peacocks because of their dichotomy—people were drawn to the beauty of their feathers but turned off by the ugliness of their behavior. It was an apt symbol for her fiction and the birds featured prominently on several of her books' covers.
