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.

Now that Prime Day is over, and with Black Friday and Cyber Monday still a few weeks away, online deals may seem harder to come by. And while it can be a hassle to scour the internet for promo codes, buy-one-get-one deals, and flash sales, Amazon actually has an extensive coupon page you might not know about that features deals to look through every day.

As pointed out by People, the coupon page breaks deals down by categories, like electronics, home & kitchen, and groceries (the coupons even work with SNAP benefits). Since most of the deals revolve around the essentials, it's easy to stock up on items like Cottonelle toilet paper, Tide Pods, Cascade dishwasher detergent, and a 50 pack of surgical masks whenever you're running low.

But the low prices don't just stop at necessities. If you’re looking for the best deal on headphones, all you have to do is go to the electronics coupon page and it will bring up a deal on these COWIN E7 PRO noise-canceling headphones, which are now $80, thanks to a $10 coupon you could have missed.

Alternatively, if you are looking for deals on specific brands, you can search for their coupons from the page. So if you've had your eye on the Homall S-Racer gaming chair, you’ll find there's currently a coupon that saves you 5 percent, thanks to a simple search.

To discover all the deals you have been missing out on, head over to the Amazon Coupons page.

The Longest Movie Ever Made Would Take You More Than 35 Days to Watch Straight Through

A typical movie lasts between 90 minutes and two hours, and for some viewers, any film that exceeds that window is "long." But the longest film you've ever seen likely has nothing on Logistics—a record-breaking project released in Sweden in 2012. Clocking in at a total runtime of 35 days and 17 hours, Logistics is by far the longest movie ever made.

Logistics isn't your standard Hollywood epic. Conceived and directed by Swedish filmmakers Erika Magnusson and Daniel Andersson, it's an experimental film that lacks any conventional structure. The concept started with the question: Where do all the gadgets come from? Magnusson and Andersson attempted to answer that question by following the life cycle of a pedometer.

The story begins at a store in Stockholm, where the item is sold, then moves backwards to chronicle its journey to consumers. Logistics takes viewers on a truck, a freight train, a massive container ship, and finally to a factory in China's Bao'an district. The trip unfolds in real time, so audiences get an accurate sense of the time and distance required to deliver gadgets to the people who use them on the other side of the world.

Many people would have trouble sitting through some of the longest conventional films in history. Kenneth Branagh's Hamlet (1996) lasts 242 minutes, and Joseph L. Mankiewicz's Cleopatra (1963) is a whopping 248 minutes long. But sitting down to watch all 857 hours of Logistics straight through is nearly physically impossible.

Fortunately, it's not the only way to enjoy this work of art. On the project's website, Logistics has been broken down into short, two-minute clips—one for each day of the journey. You can watch the abridged version of the epic experiment here.
