Solutions of bioluminescent bacteria can create FOMO-inducing living art

A 2002 exhibition at Montana State University-Bozeman placed the bacteria onto petri dishes that served as macroscopic pixels to create images. Once the bacteria finished eating all the food in the sealed dishes, the light slowly faded away, ending the exhibit.

Underwater nighttime photos capture the ocean's diversity

Self-taught photographer Steven Kovacs explores Palm Beach's ocean after sunset, capturing tiny sea creatures in deep waters. Over eight years, he's dived into Florida's eastern coast, drifting from 0 to 100 feet, photographing rarely seen larval fish. Lacking formal marine biology training, Kovacs collaborates globally to identify species like cusk eels and the female blanket octopus, known for its revealing membrane. Check out his photos here.

Astrophotographer Vincent Bouchama's stellar photo archive

Astrophotographers specialize in collecting as much light from celestial objects as possible while minimizing the movement of the object they're capturing. It's a unique skillset—requiring unique tools—but the results are often universally...

Georgia O'Keeffe's flower paintings are often assumed to be sexual, though the artist claimed she was simply interested in highlighting the beauty of flowers that most people neglect

The weakest form of light that is dangerous to humans is ultraviolet

Unlike radio waves, microwave, infrared, and visible light, UV light can produce chemical changes, such as curing adhesives and resins, causing substances to fluoresce, and destroying the genetic material of microorganisms. This makes UV light useful for sterilization, forensics, and quickly drying nail polish.

Massive blooms of microscopic plankton called dinoflagellates produce the neon blue light seen in glowing tides.

O’Keeffe discredited sexual interpretations of her flower paintings

In 1943, the artist famously explained her intention to call attention to flowers by making them large and detailed. O’Keeffe added that while she wanted people to notice her flowers, they ended up projecting their own associations that didn’t reflect her own ideas.

Published photography from JWST are false-color images

The James Webb Telescope captures invisible light, not photos. Scientists then color-map wavelengths of infrared light to show us the invisible universe.

Radioactivity was accidentally discovered when uranium left marks on photographic plates

In 1896, Henri Becquerel had been exploring phosphorescence—the emission of light of one color after an object is exposed to another color. He expected these emissions to come from objects exposed to sunlight, but he observed emissions after an overcast day.

Photographer finds 120-year-old time capsule, develops the photos

Photographer Mathieu Stern found a century-old time capsule in his family home containing a little girl’s mementos and two glass plate negatives. He used Cyanotype to develop the photographs, unveiling images of the child’s pets. Stern documented the process in a video on YouTube and Instagram, showcasing the final prints of the animals.

Explore a guide to photographing auroras

Using a wide aperture and increasing your camera's native ISO to a value between 3200 and 8000, depending on atmospheric conditions, will help capture as much light as possible while freezing the movement of the auroras. The camera should also be kept as still as possible and in environments with minimal weather impediments, such as clouds.

How a cut flower goes from a Colombian farm to a US vase in under 72 hours

The flower industry operates a complex logistical relay to move flowers to distant markets. Blooms are harvested before opening, chilled immediately, auctioned, and air-freighted to retailers before they are fully in bloom.

Photography was invented by a romantic artist

The invention of photography changed the landscape of art forever. The first photographs were created by Louis-Jacques-Mandé Daguerre, a romantic era printmaker, by using light and chemistry to expand upon images produced by the earlier camera obscura.

Wood that changed the color of water was the earliest recorded example of fluorescence

Lignum nephriticum, a tea used to treat kidney and urinary illnesses, was described in the 16th century as derived from white wood that turned water a bluish hue. However, in the 17th century, accounts described the wood as reddish and creating a kaleidoscope of colors in water. In 1915, the sources were identified as two different woods, which absorb UV radiation and emit visible light.

How the pigments that absorb light for photosynthesis contribute to plants' green color

Although light energy is captured to power the reactions that produce the building blocks of starch, cellulose, glucose, and other sugars, chlorophyll a and b are most sensitive to violet, blue, orange, and red light, leaving green light mostly unabsorbed. This green light is instead reflected, giving most plants this color appearance.

Photographer catches a 'once in a blue moon' shot

A rare "super blue moon" occurred in August 2023, a phenomenon which will not occur again until 2037. Photographer Andrew McCarthy caught a stunning image of the larger-than-normal orb with an ironic twist: a JetBlue flight silhouetted against the...

The Google Doodle honoring Jan Ingenhousz, who discovered oxygenic photosynthesis

Born in 1730, the Dutch scientist expanded on existing knowledge that plants produce and absorb gases in his 1779 paper, which detailed that light was necessary for the biochemical processes that produce oxygen in plant leaves. He also identified that all parts of plants produce carbon dioxide at night.

Understanding ball lightning remains an area of active research

Observations of glowing orbs of light that appear during or after thunderstorms have been documented since at least the 12th century, but their rarity and short lifetimes have made their study challenging. Some theories suggest they form when lightning vaporizes pockets of gases in the air or certain materials on the ground.

William Mumler’s spirit photography stunned and bewildered the public

William Mumler’s most famous work is a portrait of Mary Todd Lincoln accompanied by the ghost of her deceased husband, Abraham Lincoln. Other subjects of Mumler's photos claimed that the spirits standing beside them resembled their loved ones. Mumler’s method was never officially proven and continues to mystify viewers.

A Death Valley shrub optimizes its cells' organelles to photosynthesize in extreme heat

Examining the cellular structure of the plant under heat, scientists observed the formation of novel, cup-shaped chloroplasts and mitochondrial relocation, which shifted the plant's optimal photosynthesis temperature to 45 degrees Celsius (113 degrees Fahrenheit) as it tripled in mass over 10 days. Engineering these mechanisms in crops may help optimize them for hotter environments.

Scientists used mass spectrometry to determine the materials in a 1690 painting

Previously used to map the distribution of molecules on biological tissue samples, researchers combined the technique with machine learning to uncover six layers of pigments, binders, and a thin gold leaf layer within *The Marriage of the Virgin*, from a collection in the Metropolitan Museum of Art. The technique may help identify and track artists' material use to learn about pieces of unknown provenance. (Some readers may experience a paywall.)

Photolithography etches circuit components into a semiconductor wafer
