Researchers Grow Record-sized Lab Meat

2 months 3 weeks ago
Researchers at the University of Tokyo have created what they believe is the largest single piece of lab-grown meat to date: a chicken nugget-sized chunk measuring 7 centimeters long, 4 centimeters wide, and 2.25 centimeters thick, weighing 11 grams. The breakthrough, reported today in Trends in Biotechnology, uses an artificial circulatory system to overcome a fundamental limitation in cultured meat production. The team, led by biohybrid system engineer Shoji Takeuchi, grew cells around a network of semipermeable hollow fibers -- similar to those used in water filters and dialysis machines -- that deliver nutrients and oxygen throughout the tissue. Unlike most commercial approaches that produce tiny meat fragments later assembled with binders or scaffolds, this method creates a single coherent piece with more natural structure and texture. This is the first working model using tubes to grow muscle tissue into a thick slab, according to Mark Post, chief science officer at Mosa Meat, who created the world's first lab-grown hamburger in 2013. Significant hurdles remain before commercialization. The hollow fibers aren't edible and must be manually removed. Researchers are exploring automating this process or creating edible alternatives using cellulose.

Discord Begins Testing Facial Recognition Scans For Age Verification

2 months 3 weeks ago
Discord has begun testing age verification via facial scans or ID uploads for users in the UK and Australia seeking access to sensitive content. "The chat app's new process has been described as an 'experiment,' and comes in response to laws passed in those countries that place guardrails on youth access to online platforms," reports Gizmodo. From the report: Users may be asked to verify their age when encountering content that has been flagged by Discord's systems as being sensitive in nature, or when they change their settings to enable access to sensitive content. The app will ask users to scan their face through a computer or smartphone webcam; alternatively, they can scan a driver's license or other form of ID. "We're currently running tests in select regions to age-gate access to certain spaces or user settings," a spokesperson for Discord said in a statement. "The information shared to power the age verification method is only used for the one-time age verification process and is not stored by Discord or our vendor. For Face Scan, the solution our vendor uses operates on-device, which means there is no collection of any biometric information when you scan your face. For ID verification, the scan of your ID is deleted upon verification."
