Artist Screen-Prints Fabrics With Bacteria

Is there nothing bacteria can't do? Under the careful eye of researcher and designer Natsai Audrey Chieza, the itsy-bitsy organisms have taken on an unexpected new role in the fashion industry, offering a beautiful and environmentally friendly alternative to commercial dyes.

Fashion is currently facing "an existential crisis," Chieza told Mental Floss, "around the fact that it's the second-most polluting industry in the world." It's got problems coming and going: Textile production uses huge amounts of water and yields high amounts of petrochemical waste. 

Contemplating these issues, Chieza began to wonder if the solution could be biological. She began tinkering with Streptomyces bacteria, coaxing them to release their own rich natural pigments into small swatches of silk.

It's unlike any other printing process she's ever experienced, she explained, because the living bacteria are both invisible to the naked eye and somewhat finicky artistic collaborators. Room temperature, pH levels, and the size of their petri dish home all influence the way the microbes lay down their dye.

Chieza's background is in art and design, so once she knew she'd hit on something interesting, she started looking for scientific collaborators. After a stint working with synthetic biologists as designer-in-residence at University College London, Chieza crossed paths with Christina Agapakis, creative director at the self-described "organism design platform" Ginkgo Bioworks.

"Our expertise is in microbes and how to work with them and keep them happy," Agapakis tells Mental Floss. "We think that biology is such an amazing way to make stuff."

The artist and the organism designers are now "developing a lot of different things all at the same time," Chieza says. One of their biggest questions is scale—how a microscopic process could be enlarged to dye entire garments and yards of cloth, moving "from the biological to the body to architectural."

"At Ginkgo," she continues, "we're wondering how much we can make so that it can actually plug in to the demand for material resources. How do we bridge the difference between 250 milliliters and 50,000 liters?"

Part of the puzzle involves building all-new technology to house the all-new dyeing process, and ensuring that both are environmentally sound and resource-conservative.

At every step of the process, Chieza says she asks herself, "What does this all mean? How does this relate to society? Is it actually going to solve this problem?"

We're looking forward to finding out.

Watch a Chain of Dominos Climb a Flight of Stairs

Dominos are made to fall down—it's what they do. But in the hands of 19-year-old professional domino artist Lily Hevesh, known as Hevesh5 on YouTube, the tiny plastic tiles can be arranged to fall up a flight of stairs in spectacular fashion.

The video spotted by Thrillist shows the chain reaction being set off at the top a staircase. The momentum travels to the bottom of the stairs and is then carried back up through a Rube Goldberg machine of balls, cups, dominos, and other toys spanning the steps. The contraption leads back up to the platform where it began, only to end with a basketball bouncing down the steps and toppling a wall of dominos below.

The domino art seems to flow effortlessly, but it took more than a few shots to get it right. The footage below shows the 32nd attempt at having all the elements come together in one, unbroken take. (You can catch the blooper at the end of an uncooperative basketball ruining a near-perfect run.)

Hevesh’s domino chains that don't appear to defy gravity are no less impressive. Check out this ambitious rainbow domino spiral that took her 25 hours to construct.

A Secret Room Full of Michelangelo's Sketches Will Soon Open in Florence

Parents all over the world have chastised their children for drawing on the walls. But when you're Michelangelo, you've got some leeway. According to The Local, the Medici Chapels, part of the Bargello museum in Florence, Italy, has announced that it plans to open a largely unseen room full of the artist's sketches to the public by 2020.

Roughly 40 years ago, curators of the chapels at the Basilica di San Lorenzo had a very Dan Brown moment when they discovered a trap door in a wardrobe leading to an underground room that appeared to have works from Michelangelo covering its walls. The tiny retreat is thought to be a place where the artist hid out in 1530 after upsetting the Medicis—his patrons—by joining a revolt against their control of Florence. While in self-imposed exile for several months, he apparently spent his time drawing on whatever surfaces were available.

Museum officials previously believed the room and the charcoal drawings were too fragile to risk visitors, but have since had a change of heart, leading to their plan to renovate the building and create new attractions. While not all of the work is thought to be attributable to the famed artist, there's enough of it in the subterranean chamber—including drawings of Jesus and even recreations of portions of the Sistine Chapel—to make a trip worthwhile.
