Harrower is both a research ecologist and artist, and uses fibers and oils from her study organisms to manipulate the physical properties of her paints and tell the story of climate change and species loss. In her series Fungal Soil Mutualisms, she explores how the changing climate may alter symbiotic interactions between soil fungi and Joshua trees and how that could impact tree survival.

BARTHOLOMÄUS TRAUBECK

Years, 2011, Galerie Lisa Ruyter Vienna, Photo: Andreas Fleckl
Bartholomäus Traubeck builds equipment to translate the information contained in tree rings into music.
Years, 2011
Tree rings can provide information regarding the age of a tree, as well as different environmental conditions that the tree experienced throughout its life time. This can allow researchers to understand ecological conditions such as droughts, floods, temperature extremes, fires and disease. Traubeck’s equipment translates the rings on a turntable, using sensors rather than a needle, that gathers information about the wood’s color, patterns, and texture, and uses an algorithm to translate that into piano music.
WOLFGANG LAIB
Laib combines ephemeral materials—pollen, beeswax, milk, and rice—with long-lasting materials like stone, brass, and wood to create minimalist sculptures and installations. His refined shapes, warm colors, and aromatic materials invite us to slow down and contemplate the sensory richness of the world.
Milkstones
Laib carves a slight indentation in the top of a polished white marble brick and fills that indentation with milk. The milk creates a seamless skin on the top the marble—the ephemeral and permanent perfectly joined. Laib states, “how temporary milk is and how eternal a stone is.”1
Pollen Sculptures
Laib painstakingly collects pollen from the wildflowers and trees close to his home in Germany. He then carefully sifts the pollen on to a museum or gallery floor to create simple geometric shapes. Laib states, “pollen is the potential beginning of the life of the plant. It is as simple, as beautiful, and as complex as this.”2
MEL CHIN
Chin works as an artist and community activist. His collaborative projects combine pragmatic solutions to real-world problems with aesthetic and conceptual experiments.
Revival Field, 1991
Chin took inspiration from botanist Rufus Chaney’s research on hyperaccumulator plants—plants that pull heavy metals from the soil. For Revival Field, Chin planted hyperaccumaltors at Pig’s Eye Landfill, a contaminated Superfund site in St. Paul, MN. The project was conceived as a scientific experiment that asked: Can plants remove soil toxins? It was also an eco-art sculpture that highlighted the potential to remedy polluted environments.1
Operation Paydirt, 2006-Present
After hurricane Katrina stuck New Orleans, Chin decided he could help the city recover by focusing his attention on the high levels of lead in the city’s older neighborhoods. Before the hurricane hit, thirty to fifty percent of the neighborhoods’ children suffered from lead poisoning. Lead poisoning affects brain development, damages the nervous system and kidneys, and leads to behavioral problems.2 When Chin discovered that remediation of the soil in New Orleans would cost $300 million, he created Fundred—an art project that encourages children and their families to create art works in the shape of hundred dollar bills. Chin collects the Fundreds and plans to present them to Congress as a symbolic gesture that raises awareness of lead contamination and asks the government to appropriate funds to remedy the problem. Chin sees the New Orleans project as the first step in a bigger project that aims to remediate contaminated soil in cities across the U.S.3

GARY GREENBERG
Greenberg combines art, science, and engineering to create microscopic photographs that reveal the hidden beauty of sand, flowers, food, and the human body. Greenberg builds the tools of his craft; he invented the “high-definition, three-dimensional light microscopes” with which he creates his photographs.1 His images give us unfamiliar and intimate views of materials we encounter every day.
Microscopic images of retinas and bone.
Microscopic images of Royal Poinciana and Hibiscus flowers.
