Listen to audio clips from Hoover, a harbor seal named after its insatiable appetite, who learned to say English phrases such as 'hello there' and 'come over 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.

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.

Once whale songs were discovered, conservation efforts boomed

Until the 1950s, humans believed whales were mute. Once American underwater surveillance systems caught their sounds during the Cold War, the perception of the creatures changed, leading humans to campaign for whaling bans and long-term conservation efforts. These captivating whale songs can be heard throughout the ocean.

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.

Some animals may speak because of duplicated connections in the brain

Neuroscience suggests that connections responsible for motion made during embryonic brain development—such as those connecting hearing and movement pathways that allow reactive motion when started—are duplicated and connected to the larynx in some animals. This allows some mammals and song-learning birds to speak, provided they have the necessary physiological structures.

Button boards may be the next step in human-canine communication

In a viral trend, dogs have been recorded using button boards to seemingly "talk" with humans. Researchers are divided on whether this means dogs have learned language or are engaging in sophisticated behavioral conditioning.

Conan's 2000 commencement speech offers comfort and humor to young Harvard graduates

In the spring of 2000, famous late-night talk show host and comedian Conan O'Brien gave a hilarious, thoughtful speech to the graduating class at Harvard, where he graduated from in 1985. He warns that once adult life begins, any stupid mistakes made by a Harvard grad will be severely mocked. He also recounts his post-grad failures and how important they were in his success. The speech has been noted ever since as a classic example of both wisdom and foolishness.

Listen to audio recordings of forests from around the world, featuring birds chirping, water flowing, and wind flowing through the trees.

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.

Studying 'sonic' black holes

If a fish screams as it falls down a cascading waterfall accelerating to ridiculous speeds, will his fish friends above hear him scream? This analogy, odd as it is, has become an essential tool in the astrophysicists kit for learning how enigmatic black holes operate. Lab experiments mirroring the so-called sonic black hole have achieved insights for their cosmic counterparts. Read how it works in this brief piece.

How Stephen Hawking’s voice became iconic

Stephen Hawking relied on a voice synthesizer after losing the ability to speak due to complications with ALS. Despite technological advances, he refused to change the "Perfect Paul" voice, making it a cornerstone of his public identity.

The speech software's origins at MIT led to Hawking's trademark voice being American

Stephen Hawking's trademark voice is called "Perfect Paul," but it mimics Dennis Klatt, an American researcher at MIT who developed the speech synthesis technology. Klatt used his voice during this development, which was immortalized through Hawking.

Meet Clever Hans, the 1900s horse that was believed to be able to solve math equations and read German

When Clever Hans was prompted with math questions, he responded by tapping his hoof to indicate his answers. Even a panel of experts found no indication of trickery in the horse's demonstrations. However, psychology student Oskar Pfungst found that Hans stopped tapping once a subtle cue on his owner's face told him to stop. The cues were so subtle that Wilhelm von Osten didn't even know he was giving them.

Pediatricians look for a list of behaviors to signal typical hearing development

These markers of typical hearing development among infants and toddlers include turning head to sound sources within the first five months of life, babbling by about 11 months, and trying to imitate simple words by 17 months of age.

Squeaky toys mimic prey sounds, appealing to dogs' hunting instincts

Squeaky toys provide instant feedback and gratification, and they can also prevent boredom and improve canine dental health. Some toys contain seemingly silent squeakers that use ultrasonic technology to emit sounds only audible to dogs.

The Victor Talking Machine Company's logo, an iconic image used on early record players, was based on a painting portraying a dog mourning its dead owner.

See a wild bear observe fellow bears at the zoo

At the Sequoia Park Zoo in California, a wild bear visited the bear enclosure to see three bears in captivity. Zookeepers referred to him as a "polite visitor," adding, "He stayed on the boardwalk path, kept two feet on the ground, and didn't try to climb over the railings!"

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.

Reports of a recording of Whitman's voice are said to be a hoax

A recording of Whitman reading a portion of his poem "America" has been mass-produced and broadcast, but the Library of Congress and other scholars say the recording is a hoax.

How the National Science Foundation helped cement the use of American Sign Language

Before the 1960s, deaf students were taught to read lips and pronounce words without signing, which was not considered a true language. After noticing that students nonetheless signed when communicating, American linguist William Stokoe conducted NSF-funded research that showed that signing met the definition of oral languages, thus establishing ASL.

Watch this octopus win every single Escape Room challenge

Octopuses are famously intelligent, solitary creatures covered in hundreds of chemical-sensing suckers. They're also pretty fascinating pets, and even enjoy playing. The crew at OctoLab put one of its more playful mollusks into four different Escape Room-like cages to see how long it would take for it to escape. Watch this video to see the brilliant, if a bit unsettling, methods the animal uses.

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.

Big Ocean is breaking barriers as the world's first deaf K-pop boy band

The three-person boy band—whose members have different levels of hearing loss—use light systems, vibrations, and a mix of Korean and American Sign Languages, as well as International Sign (which isn't a whole language), to communicate and keep their dance routines in sync. In this interview, a band member with partial hearing describes their challenges.

Computer systems create artificial voices by stitching together phonemes—individual sounds that make up speech, such as 't,' 'long a,' and 'k' to say 'take.'

Bob Hope's radio shows brought stand-up to the masses

Bob Hope’s 1930s variety shows featured comedic monologues. Unlike the tightly scripted and evergreen sets of vaudeville, Hope’s monologues leaned into topical and political humor, sometimes to the disapproval of his network.

The journalist who let AI speak with his voice

Journalist Evan Ratliff became the object of his own story: He opted to clone his voice, feed it into an AI chatbot, and have it do the talking. What could seem like a fun experiment ended up revealing just how far the capacity of artificial intelligence can go in imitating our identities. Hear the ins and outs of how Ratliff achieved this in this fun and thought-provoking episode.

Watch a medley of Pets.com commercials with the famous sock puppet mascot

Pets.com used a sock puppet decorated like a dog (operated by comedian Michael Ian Black) as the company's mascot. The sock puppet became synonymous with the brand. An auto lender company called BarNone Inc. later purchased the sock puppet for $125K and rebranded it with the slogan "Everybody deserves a second chance."

The word 'hoax' comes from the phrase 'hocus-pocus'

The famous phrase "hocus-pocus" combines liturgical Latin and gibberish. It's a silly series of words often said during magic tricks. The phrase naturally evolved into "hoax" over time and became a standard English word around the year 1800.

Early 20th-century debates about horses with "paranormal mathematical abilities" helped shape modern approaches to psychological research.

Harvard drowned rats for this?

Harvard's 1950s rat study was ethically questionable, but scientifically profound. One rescue attempt made rats swim 40x longer. The finding: hope isn't poetic, it's biological.
