Nine different studies exploring animals' relationship to music

Noise pollution from humans and technology alters animal behavior

Animals may experience chronic stress and health issues due to noise pollution, which often interferes with their mating sounds. Due to traffic, nightingales sing louder on weekday mornings, and birds near airports start singing earlier to avoid upticks in takeoffs and landings.

Can animals understand fairness?

Academics have long wondered if fairness is solely a concern of humans. In the largest meta-analysis to date, UC Berkeley researchers tested whether monkeys felt jealousy after receiving unequal rewards. The patterns showed low evidence for inequity aversion and instead frustration due to their expectations not being met by humans. These findings suggest that pursuing fairness and equality is uniquely human.

Humans are wired to pick up on each other's emotion, making laughter contagious

The reaction plays a key role in establishing interpersonal connections and relieving stress by releasing endorphins—feel-good hormones. A 2021 study identified at least 65 animal species that produce playful sounds, such as laughter.

Similarities between human and animal sleep

Have you ever noticed the wide-ranging differences in sleep between humans and animals? Sleep as a necessity is present amongst all animal species, but the specific patterns of sleep vary widely. Just think of the differences between how an owl, a whale, and a horse might sleep. This helpful resource from the Sleep Foundation explores the relations between human and animal sleep, complete with some fascinating statistics about sleep patterns throughout the animal kingdom!

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.

Brain studies suggest some animals do dream (sort of)

Studies on sleeping cats, rats, fish, and finches show that their brains fire as if performing actions from waking life. Spiders and insects also have REM-like sleep. Whether these findings indicate that animals dream depends on one's definition of dreaming.

Playing music enhances the creation, storage, and retrieval of memories

Scans of the brains of individuals who play instruments have shown enhanced connectivity between multiple brain regions—visual, auditory, and motor cortices—and the corpus callosum, which connects the two brain hemispheres. These complex connections are strengthened through practice and then used in other activities that involve both logic and creativity. The brains of musicians also appear to give experiences multiple types of memory tags, such as audio, emotional, and conceptual, improving their processing.

50 years of research has focused on unraveling the relationship between music and frisson

One insight reveals that musical passages with surprising volume changes or unexpected harmonies and beauty are more likely to trigger frisson, perhaps because they upend listeners' expectations.

Study shows singing to babies improves their well-being

In a study of 110 parents and their babies across a span of four months, singing boosted infant mood and reduced fussiness. Follow-up studies are aimed at exploring whether singing can alleviate caregiver stress and postpartum depression.

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.

How can octopuses and MDMA help scientists understand the human brain?

Research shows that psychedelics may induce something called "critical periods" in the adult brain, which can make our brains more open to learning and changing, like they once were back in early childhood. Psychedelics similarly change how social creatures like octopuses behave, which demonstrates that these animals could help us better understand our own neurobiology.

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.

What to listen to if you want to focus

Have you ever put your headphones in, turned on your favorite playlist, and tuned out the rest of the world? That’s the power of music. It can improve your mood, reduce stress, and enhance focus. But what kind of music is best when working or studying? Check out this list for some suggestions.

Listen to the music David Attenborough recorded during his expeditions around the world

During this audio documentary feature, Attenborough plays musical performances by communities he encountered while producing natural history series, including Gamelan orchestras in Bali, palace music in Tonga, and Aboriginal didgeridoo players. With each recording, he provides anecdotes about when it was made, decades ago.

Crows are believed to have intelligence on par with a seven-year-old child and demonstrate complex behaviors, from problem-solving with tools to recognizing human faces.

Yes, many animals get malaria—not just humans

Birds, rodents, monkeys, lizards, bats, apes, and livestock are among the species that can become infected with malaria. Infected animals' symptoms often resemble those of humans, including fever, lethargy, loss of appetite and difficulty breathing. Birds will also have ruffled feathers and drooped heads.

The secret life of urban crows

Before humans, the Soviet Union and the United States sent animals—including apes, dogs, and cats—to space during the Space Race.

Cats began cozying up to humans around 10,000 years ago

The feline family is a hugely diverse group of lions, panthers, and kitties that have spread all over the world. The ancestors of the cats we love today helped solve rodent problems when humans first invented agriculture. They've been worshipped, loved, and scorned by humans since.

The animals that paved the way for space travel

The history of animals in space exploration is often overlooked. Before humans first made their way to space in 1961, fruit flies, primates, and canines preceded us. Watch this video for a further appreciation of the contributions and sacrifices made by animals for scientific progress.

How the cicada entered popular music

For significant swaths of the country, cicadas are a calming summer soundtrack. In the past few decades, though, the insects' distinct sound have also entered the music world, providing drone and ambience for a range of musicians.

Opera melodies from centuries ago still appear in TV and movies today

Even if you haven't witnessed an 18th century opera, you've likely heard melodies from one in modern media like “Apocalypse Now” and “Sesame Street.” Today, sports events, movies, and television feature operatic melodies even over a century after they were written.

Some animals have little or no bacterial populations in their gut

Gut microbiomes are essential to human health, but many animals have a much smaller, transient, or even nonexistent microbiome. The discoveries have advanced our understanding of the evolution of the human microbiome.

YouTube's 10 most viewed music videos of all time

Bees are more likely to remember a flower if its nectar contains caffeine

Plants want pollinators to keep coming back, so the finding suggests that some plants, such as Citrus and Coffea species, have evolved to include caffeine in their nectar. Researchers suggest the findings could help develop methods to reinvigorate pollinator populations.

Some critics argue bebop and free jazz led to jazz's decline in popularity

Although jazz was once a popular art form, it has largely been confined to the margins of pop culture, with many of the genre's current bestselling albums from previous decades. Some critics argue that this is because the music betrayed its position as dance music and focused instead on musical proficiency.
