Audio and visual cues from "Titanic," Pink Floyd, and more can provoke goose bumps

Music may give some of us the chills and goose bumps—perhaps because it shocks us

The science is still unsettled about why music can trigger a chill down your spine, formally known as frisson, but one theory is that anything surprising to the nervous system—including sudden beat drops or unexpected harmonies—stimulates a type of alarm response that gives rise to this feeling.

The brains of people who experience frisson have unique neural pathways

A small 2016 study aimed to investigate the behavioral and neural differences between 10 individuals who experience goose bumps when listening to music and 10 who typically don’t. Scientists reported that individuals experiencing musical chills had greater white matter connectivity in specific auditory, emotional, and social processing areas of the brain.

Goose bumps are often triggered by emotions

A physiologist and professor of zoology explains that the subconscious release of adrenaline, a stress hormone, causes a contraction of skin muscles. It’s released in several situations, including when humans are cold, afraid, or feel strong emotions. (Some readers may experience a paywall.)

Artificial goose bumps could theoretically be used for information storage

Inspired by how fine hairs stand on the skin with goose bumps, researchers have recently created artificial skin that raises artificial goose bumps when exposed to a laser. This type of precise, localized, and controllable system could potentially fuel later development of programmable machines that could be used for information storage.

Scientists are learning to guide your dreams using sound and touch

Researchers are using a technique called "targeted dream incubation"—where stimuli like sounds or vibrations are introduced as you drift off—to influence dream content and potentially improve creativity, memory consolidation, and PTSD treatment. With the same mechanism, companies could theoretically target sleeping consumers with brand suggestions while they're unaware and neurologically susceptible, or assist in reducing nightmares.

Horror video games rely on terrifying sound design

Horror has become a popular gaming genre, which designers say is due, in large part, to the games' soundtracks. Don Veca, the audio director for the game Dead Space, said, “Sound and music prepare the player to be scared – it’s all about the buildup, the tension, and then the release when something jumps out at you.”

The "reminiscence bump" causes memories from adolescence to last

Research shows that the "reminiscence bump" phenomenon, which applies to memories formed between the ages of 10 and 30, contributes to songs from those ages triggering the most intense nostalgia. This may be due to biological and hormonal changes enhancing memory effectiveness during adolescence.

Researchers are studying roller coasters to improve mental health treatments

Scary rides stimulate our fight-or-flight response while simultaneously releasing feel-good endorphins like dopamine, serotonin, and oxytocin. Once we realize we're in a safe space, we can enjoy the ride and even feel confident and relieved by the accomplishment of overcoming a fearful feat.

Neural replays in mice help explain food aversions

Princeton University scientists published research in 2025 analyzing how mice learn to associate certain foods or flavors with feeling ill—even when there’s a time gap between eating something and feeling sick. The work, performed with grape Kool-Aid and injections of a substance that made mice sick, traced the literal “gut reaction” of how gut distress signals are linked to neural replays of what the mouse ate.

Listen to samples of 'sounds' produced by the sun's internal vibrations

Sonification can turn otherwise inaudible vibrations into audible sounds, just as scientists colorize images of celestial objects taken outside the visible range into colors our eyes can interpret. This has been used to turn the vibrations within the sun detected by the Parker Solar Probe into audio clips that resemble chirping and whistling.

We may be using Q-tips in our ears—even when we shouldn't—because they can stimulate pleasure nerves

People continue to use Q-tips inside their ears even though we know it's risky. Some clinicians suggest that beyond the desire to get water out, this may be because the nerve bundle called the vagus nerve, which spans from the brain to the large intestine, can be stimulated that way, causing a pleasurable sensation in other body parts including the heart, belly, or genitals.

Eleven deaf men played a pivotal role in America's human spaceflight program

In the mid-20th century, 11 deaf men volunteered for a series of experiments that offered unprecedented insights into the effects of weightlessness on the human body. Most of the men had become deaf in early childhood as a result of spinal meningitis, a condition known to damage the vestibular system and make them less susceptible to motion sickness. For a decade, these men participated in extreme motion sickness situations, including living in a slowly spinning room, spending time in centrifuge pods designed to simulate hypergravity, and flying in parabolic flights sometimes referred to as the "Vomit Comet."

Accounts of near-death experiences share similarities with hallucinogens

This short film explores human experiences of dying, blending personal reflections with scientific insight. It aims to illuminate the emotional, psychological, and physiological aspects of that final transition, and draws out similarities of psychedlic drug use and accounts of near-death experiences.

Visualizing shifts in emotional performance in film

Computational scientists were curious: has the intensity of emotional expression in films changed over the decades? Using their sophisticated analytical models, the researchers discovered actors' emotional performance has declined in intensity over time. They believe the close-up shots common in contemporary film-making allows actors to be more subtle in their performance. Check out the main takeaways and charts with this unusual study.

How Netflix's sound logo 'Tudum' was designed as a key sonic differentiator

Disney’s “Feeling Fireworks” uses water jets and a latex screen to replicate fireworks for blind individuals. Such technology may also provide inclusive experiences for the deaf community, though as of 2024, there are no plans to implement them in Disney parks.

A new scan of the Titanic reveals details about its final hours

Using over 700,000 images captured by underwater robots, researchers created a highly detailed 3D "digital twin" of the Titanic. The analysis gives us new insights into the life of the ship that lays 3,800m down in the icy waters of the Atlantic. Emerging details from close-up images, such as a smashed porthole likely caused by the iceberg, match the eye-witness accounts of what happened. Read for more insights into the devastating wreck.

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

Surfer's ear, from repeated cold water exposure, leads to new bony protrusions in the ear

Frequent exposure to icy cold water, typical in surfing, can cause tiny bony growths to develop in the ear canal, informally called surfer's ear. While the exact cause for these growths is unknown, it may be the body's protective response to shield the ear drum from the cold. These protrusions can heighten the risk of swimmer's ear, lead to wax buildup, and result in hearing loss.

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.
