Dress Made of Living Mycelium Can Renew and Repair Itself

2 weeks 6 days ago
Researchers in China have developed a living mycelium textile that can self-clean, renew its surface, and partially repair holes when treated with a nutrient solution and fresh fungus. The material can also gain added properties such as blue pigmentation or UV resistance by co-culturing it with yeast or other fungi. Dezeen reports: The breakthrough from the researchers at the Shenzhen Institutes of Advanced Technology is a type of engineered living material (ELM) -- a material built off living organisms that stay active even after they're fabricated into their final form. [...] By working with living but dormant cordyceps militaris fungus instead, the researchers have been able to take advantage of its biological functions. The result is a material that is self-renewing and responsive to its environment, in ways that could one day transform architecture and clothing -- as seen in a prototype dress created together with material innovation company Peelshere. It can also be adapted by mixing in other fungi or yeast, lead researcher Ke Li and her team detail in a paper in the peer-reviewed journal Science Advances. In it, they describe a "programmable fungal platform" where mycelium is treated like a modular system, with the sheet material forming a base structure and extra biological abilities, such as colour and UV resistance, becoming "plug-and-play" add-ons via other organisms. This gets their textile closer to the self-repair, environmental responsiveness and controllable functionality that is the promise of engineered living materials, they argue. The ELM's self-renewing and semi-repairing functionality comes from the mycelium base structure. Following drying at 45 degrees, the material is not quite living and not quite dead, but instead in a "low-metabolic, dormant-like state", Li told Dezeen, meaning it is not actively growing. However, new growth can be triggered by applying a nutrient solution of potato water, leading the dormant mycelium to germinate, send out new fungal filaments and renew the material's surface. When this nutrient solution is applied over a hole, along with a small patch of fresh fungus, it triggers the living cells to grow across the gap, seamlessly repairing the surface without any adhesives or stitching. The material is also naturally self-cleaning, as it is hydrophobic. "Its distinctive surface texture, biological colouring, controlled repair and biodegradability may be particularly useful in applications where visual expression and a defined product lifetime are important," said Li. "Further improvements in durability, moisture resistance, safety and manufacturing consistency would be needed before it could be considered for routine clothing or permanent architectural use."

Error'd: Time Wounds All Heels

Looked to the past for some time-traveling entries to round out a themed post. They're 25% fresh.

Robert apparently got a notification of a planned past delivery. It could be just a case of two systems that don't report different time zones, but even so, that's a wtf. Says he: "I just received an email from OnePlus this morning letting me know they have updated the planned delivery date for my order to Yesterday. I guess the delivery driver is going to time travel to get there on time since it still hasn't arrived. "

Kinkster Ypsilon Omega was really turned on by a time-traveling hottie who posted a photo an hour before joining. "(Heavily redacted screenshot.) Either Fetlife (a kink community website) is very welcoming to time travelers, or allows new members to upload their profile picture. Because time handling code surely never fails..."

ERIC P. shared a photo from 2023. "My 2008 Ford has suddenly time-warped 1024 weeks into the past. GPS date roll-over bug. No updated firmware available. No way to set the calendar manually. No way to turn off the date display."

Marc Würth "... just added a new RSS feed to my Netvibes dashboard (great tool otherwise, by the way). While it was still fetching the feed, it showed these peculiar crawling stats. Once fully loaded, it showed sane info, though." I'm curious about the specificity of 261 years.

Quite recently, an anonymous slightly flexed "Not only did I receive two parcels prior to the Roman conquest of Britain, but the date calculation for the combined notification has then failed and returned the Unix epoch." For those who missed the flex, dig Wikipedia: "Wardian London is considered to be the most expensive residential development in East London." I guess they can afford professional time travelers.
