Modern media exposure may impact whether people dream in color or black and white

How dreams affect your memory

In 1999, scientists conducted a study in which participants were asked to recall images flashed before them for milliseconds. They found that participants who slept before recalling the information performed better than those who had been asked to recall the same information that same day. This was some of the earliest convincing evidence of how crucial sleep is for learning and memory, findings that current research continues to strengthen.

Roughly one in every 250 has never remembered a single dream

Most people dream for about two hours every night and recall about two dreams per week, and memory encoding is especially fragile upon waking. Alarms can knock dreams right out of one's head, and dream recall may be influenced by personality, interest, and socialization.

The dreaming brain, as understood by scientists

Technology has advanced to where the seemingly separate fields of psychology and neuroscience are asking the same questions about dreams, such as whether they're more closely related to perception or visualization. Some field-intersecting findings include research that shows people with impaired face perception don't dream of faces, those with brain legion-related cognition difficulties deal with similar issues in dreams, and children's dreams change in parallel to their cognitive development.

Researchers believe the brain consolidates memories, processes emotions, and plans for the future during dream states

Visualizing how we dream via Google search trends

When dreams perplex us, we often want to understand them—and in the age of Google, millions go to its search engine to find answers. Now, researchers have compiled a decade's worth of dream-related queries to glean dream trends across seven languages.

Why your favorite color is probably blue

From a young age, we are primed to choose a favorite color, but strangely as we grow up, our preference often changes—and it’s largely due to influences outside our control.

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.

Studies of psychedelic use may help shed light on the nature of consciousness

The nature of consciousness—what it is, where it comes from, and how it manifests as moment-to-moment experience—remains under debate by scientists. Recent studies show psychedelics were found to boost low-frequency brain signals known as delta waves, a behavior also seen during dream states.

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.

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.

Red and blue election maps are a modern media invention

The red–blue color scheme used on election night maps emerged in the 20th century as television networks adopted color graphics to make results easier to follow. The association of red with Republicans and blue with Democrats later became standardized.

Around 5% of people report memories of a near-death experience

Near-death experiences are moments reported by people who’ve come close to death, often associated with bright lights, out-of-body sensations, or encounters with otherworldly beings. While scientific research offers theories ranging from brain chemistry to psychological coping mechanisms, no single explanation fully captures the mystery of these experiences.

'The Wizard of Oz' wasn't the first film to use Technicolor

Technicolor provided warm color to films. it was first used in 1917. But the 1939 film used Technicolor in such an intentional way—by having Dorothy exit a dull, sepia-toned world before entering the Technicolor Oz—it popularized the technology, even though audiences had likely seen it used before then.

Dove’s ‘Real Beauty’ campaign sparked conversations about beauty standards in media

For the 20-year anniversary of the campaign in 2024, Dove conducted a brand-commissioned study to gauge how perceptions of beauty standards have shifted since its launch. While 81% of US women thought “the media and advertising set an unrealistic standard of beauty that most women can’t ever achieve” in 2004, the share had shrunk to 69% in 2024. Watch the ad here.

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.

The de stijl movement embraced bright colors and abstract images

Over time, the World Cup became a commercial powerhouse

The 1954 World Cup featured the first live black-and-white televised broadcast of the event, and, in 1970, FIFA introduced color broadcasts in primetime. Increasing revenues pushed private networks to aggressively bid for broadcast rights. Today, the event is a commercial powerhouse, with the 2026 World Cup projected to generate around $4B in TV rights revenue.

The 'overview effect' heightens one's sense of unity and connectedness

Coined by space philosopher Frank White in 1987, the term refers to the paradigm-shifting experience a person undergoes upon viewing Earth from space. Commercial spaceflights aim to bring this perspective to a broader audience, inspiring changes in behavior and worldview among participants.

Aphantasia involves a lack of mental images—but doesn't affect behavior

The condition, generally known about for over a century, first received its name in 2015 by researcher Adam Zeman. An estimated 4% of people lack this ability to perceive mental images, and research suggests this deficiency does not have any practical impact on behavior.

Americans think being informed is a priority for voting, but don't prioritize reading the news

Many Americans report feeling "news fatigue," finding much of the news they encounter irrelevant. Still, being informed is recognized as a major civic duty. Many Americans have stopped seeking out the news or are far more selective about where they receive it, and an increasing sense that its up to individuals to confirm the facts they're being told.

In the years 2001 through 2003, 72% of adults under age 35 said they drank. But by the time the years 2021 through 2023 rolled around, only 62% of under-35 adults could say the same, according to one recent study.

Nostalgia is a psychological coping mechanism that can help combat loneliness—but it's created from bias

Researchers have observed that though nostalgia can help counteract feelings of loneliness, our memories of the past are somewhat rose colored. Negative emotions seem to fade faster than positive ones, a phenomenon that they suggest may be a psychological coping mechanism so that memories don't hurt every time they're recalled. (Some users may experience a paywall.)
