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.

It's difficult to think of a hobby or job that doesn’t involve some element of coding in its execution. Are you an Instagram enthusiast? Coding and algorithms are what bring your friends' posts to your feed. Can’t get enough Mental Floss? Coding brings the entire site to life on your desktop and mobile screens. Even sorting through playlists on Spotify uses coding. If you're tired of playing catch-up with all the latest coding techniques and principles, the 2020 Python Programming Certification Bundle is on sale for $49.99 to teach you to code, challenge your brain, and boost your resume to get your dream job.

Basically, coding is how people speak to computers (cue your sci-fi vision of a chat with a creepy, sentient computer), and while it does sound a bit futuristic, the truth is that people are talking to computers every day through a program called Python. The 2020 Python Programming Training Certification Bundle will teach you how to build web applications, database applications, and web visualizations in the world’s most popular programming language.

Python is also the language computers are using to communicate back to programmers. You’ll learn how Jupyter Notebook, NumPy, and pandas can enhance data analysis and data visualization techniques with Matplotlib.

Think back to your creepy, sci-fi visual from earlier; was it some form of artificial intelligence? Contrary to what you may have seen in the movies, artificial intelligence is something you can learn to create yourself. In the Keras Bootcamp, you’ll learn how to create artificial neural networks and deep-learning structures with Google’s powerful Deep Learning framework.

Coding is associated with endless text, numbers, and symbols, but the work code is performing is hardly limited to copy. Dig deep into image processing and computer vision tasks with sessions in OpenCV. You’ll give yourself an extra edge when you can use Python for sifting through information and implement machine learning algorithms on image classification.

Explore coding education with the bundle’s 12 courses, spanning from beginner to advanced levels, to elevate your skillset from home. The 2020 Python Programming Certification Bundle is on sale for $49.99.

Watch: This Crashing Wave Art Installation in South Korea Brings Seaside Tranquility to a Busy City

These waves won't unexpectedly soak your beach towel when the tide comes in.

Since residents of Seoul, South Korea, can’t exactly enjoy the sight of ocean waves breaking on the shore during their lunch hour, a design house is bringing them the next best thing: An enormous screen that plays realistic waves on a loop in the middle of the city.

Travel + Leisure reports that the installation, titled WAVE, is an anamorphic illusion, a distorted image that the viewer must observe from a specific angle for it to appear multi-dimensional. It’s on display in K-Pop Square at the Coex Convention and Exhibition Center in the district of Gangnam, but you don’t have to book an international flight to check it out—the creator, a design company called d’strict, shared a mesmerizing video of the work on YouTube.

Over about two months, developers molded two LED displays together to create a screen approximately 262 feet by 65 feet, with a resolution of 7840 pixels by 1952 pixels—almost twice the resolution of ultra-high-definition. In other words, the waves on this screen look more convincing than footage of the actual ocean would on your state-of-the-art living room TV.

For 18 hours a day, locals can watch icy blue swells slosh against the sides of the virtual tank, complete with the tranquil sounds of crashing waves (though they’ll have to rely on their imaginations to catch a whiff of salty sea spray).
