Visualizing a synaesthetic soundscape

Individuals with synesthesia experience involuntarily overlapping sensations

Tasting words or seeing colors in music results from the brain retaining extrasensory connections from infancy. While most lose these neural pathways during development, about 4% of people are synesthetes, maintaining them without realizing it's unusual.

Examining self-diagnosed synesthesia

A growing number of people on social media claim to have a perceptual condition that lets them smell colors, see music, or taste sounds. But do they really?

Brain implants can help colorblind people hear colors

Colorblind artist Neil Harbisson was born into a world of grey. In 2004, he had a chip installed connected to an external color frequency sensor. Once the sensor "reads" a color, it sends a signal to the chip and plays an associated sound both in and outside Harbisson's head.

Listen to a jazz composition triggered by the New York City Subway

A creative coder created a (synthetic) jazz ensemble that uses the locations of the city's trains to determine its performance. It's both a fascinating bit of internet culture and a fitting homage to New York, one of jazz's major hubs.

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.

How the brain processes a calendar year

When most of us picture a calendar year, we have a foggy image in our minds of the months, in rough, calendar-like grids. But for some folks, that picture is a whole lot more clear. Around 1 percent of the population has a strange ability known as "calendar synaesthesia," which means they're able to visualize in crisp detail an elaborate calendar of the months of the year. Learn how it works here.

The science behind why some noises have color names

Different noise colors (white, brown, pink, blue) have been proven to affect mood and focus. An audiologist explains that these sounds are named after specific light wave frequencies. While individual preferences vary, certain noises consistently impact sleep, stress reduction, cognitive performance, and problem-solving. The article highlights how these sounds can enhance productivity, relaxation, and even gaming experiences.

Humans experience the world subjectively. What does that mean for scientific research?

When you close your eyes, do you see static or colorful patterns or an "intrinsic grey" known as Eigengrau in German? This variation of our internal experiences is just the tip of the iceberg, one that scientists are increasingly studying and...

Clicking on an entry will take readers to a new page where they can learn about the chemistry and pharmacology of each compound, as well as the drug's possible applications.

Color originates from the brain processing light of varying wavelengths

Various geometric models, including Newton's color circle of hue and saturation and the horseshoe-shaped XYZ space for mixing colors via vector mathematics, have been proposed to describe colors accurately. However, these models do not encapsulate the variety of psychological effects that cause perceived colors to differ from mathematical representations.

Wearing a 'schizophrenia simulator,' designed to build empathy for patients, CNN's Anderson Cooper finds he struggles to function

The aesthetics of the James Webb images

The highly popular images produced by the James Webb Space Telescope are an artful collaboration between data science and visual designers. The raw data reflects real physical aspects of space, but it arrives without visual representation. Visual experts assign colors to specific wavelengths, crop and orient images in an accessible way, and consider the emotional impact of images as they incorporate design principles into the final product. Learn the fascinating details here.

The ideas of Einstein and Freud combined in 'The Persistence of Memory'

The Persistence of Memory was painted on a canvas roughly the size of a sheet of paper, depicting a desolate landscape with melting clocks, ants, and a distorted figure. The piece incorporates Freud and Einstein's ideas, resulting in a haunting composition symbolizing time's fluidity and Dalí's personal anxieties.

One classical musician arranged a work specifically for yoga

In the middle of a yoga class, Ellen Fishman noticed that sitting closer to a speaker allowed her to feel the music in her body, enhancing her overall experience. She arranged music for a string ensemble with a yoga session in mind. The group, StringFlo, now performs the work live in yoga classes.

Misophonia is a neurological disorder where sounds trigger strong emotions

The phenomenon is characterized by decreased tolerance to specific sounds, such as heavy breathing, pen clicking, and water dripping, which trigger a fight-or-flight response. The resulting emotions, which can range from irritation and disgust to anxiety and fear, can be overwhelming and uncontrollable.

In 2015, a custom virus program was used to destroy and transform art images

Visualizing a joint under attack from rheumatoid arthritis

A particularly difficult arthritis subtype is rheumatoid arthritis, a painful condition provoking a vicious cycle of joint inflammation, destruction, and dysfunction. It begins with a misfiring of the patient’s own immune system—for unknown reasons, it identifies joint and cartilage cells as foreign, initiating an attack to eliminate the supposed "invaders."

Writer William Gibson invented the term 'cyberspace'

The science-fiction writer coined the term in his 1982 short story "Burning Chrome" to describe "a consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts...A graphic representation of data abstracted from the banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the nonspace of the mind, clusters and constellations of data. Like city lights, receding."

Miles Davis' 'Kind of Blue' changed the genre by pioneering modal jazz

Davis was an adept bebop trumpet player, but he grew tired of the style. With 1959's "Kind of Blue," he pioneered a new style of jazz, called modal jazz, that focused less on improvising on chord progressions and more on open, tone-based expression.

A Harvard radio station once dedicated 24 hours to Jandek

Koji Kondo composed the game’s iconic soundtrack with a limited palette of sounds

The game’s soundtrack and effects were limited by the Nintendo Entertainment System’s 8-bit hardware, which had significantly fewer sounds than a typical synthesizer. That didn’t stop Kondo from writing some of the most recognizable video game music in history.
