Scientists Built a LEGO 'Electrospinner' to Improve the Texture of Lab-Grown Meat

A group of food scientists who are working to create lab-grown meat have found inspiration in an unlikely source: LEGOs. According to Food & Wine, researchers from Pennsylvania State University and the University of Alabama used LEGO components to create a device capable of improving the texture of the meat they were cultivating. Their findings were recently published in the journal Food Hydrocolloids.

Any protein that comes from “stem or stem-like animal cells” that are cultured in a lab can be considered lab-grown meat, according to Penn State. While lab-grown meat can be labeled a meat substitute because it requires far fewer animals for its production, it remains to be seen whether vegans and vegetarians will be willing to eat it.

Lab-grown meat is still very much in the development stages, and scientists are working on ways to improve the texture. Because cultured muscle cells don’t have any particular structure when they grow, the meat generally comes out resembling ground beef. That’s fine if you’re hoping to make more humane tacos, but it presents a challenge when trying to create, say, a lab-grown steak.

This is where the toy bricks came in. Researchers used LEGO Power Functions to create an electrospinning device that was capable of turning starch fibers into a structured meat “scaffold.” The plastic pieces were ideal because they weren’t conductive, which was crucial because the researchers were working with water and ethanol.

Unlike scaffolds that produce plastic fibers for biomedical purposes, the LEGO device was capable of spinning corn-derived fibers. In other words, what's going into the meat is entirely edible. “The idea is we could make a nice, edible, clean scaffold for our clean meat,” Gregory Ziegler, a Penn State professor and director of graduate studies at the university's Department of Food Science, told Food & Wine.

Scientists are now looking for ways to improve their equipment in order to churn out larger amounts of starch scaffolds.

You Can Now Go Inside Chernobyl’s Reactor 4 Control Room

The eerie interior of Chernobyl’s Reactor 4 control room, the site of the devastating nuclear explosion in 1986, is now officially open to tourists—as long as they’re willing to don full hazmat suits before entering and undergo two radiology tests upon exiting.

Gizmodo reports that the structure, which emits 40,000 times more radiation than any natural environment, is encased in what's called the New Safe Confinement, a 32,000-ton structure that seals the space off from its surroundings. All things considered, it seems like a jolly jaunt to these ruins might be ill-advised—but radiology tests are par for the course when it comes to visiting the exclusion zone, and even tour guides have said that they don’t usually reach dangerous levels of radiation on an annual basis.

Though souvenir opportunists have made off with most of the plastic switches on the machinery, the control room still contains original diagrams and wiring; and, according to Ruptly, it’s also been covered with an adhesive substance that prevents dust from forming.

The newly public attraction is part of a concerted effort by the Ukrainian government to rebrand what has historically been considered an internationally shameful chapter of the country's past.

“We must give this territory of Chernobyl a new life,” Ukraine's president Volodymyr Zelensky said in July. “Chernobyl is a unique place on the planet where nature revives after a global man-made disaster, where there is a real 'ghost town.' We have to show this place to the world: scientists, ecologists, historians, tourists."

It’s also an attempt to capitalize upon the tourism boom born from HBO’s wildly successful miniseries Chernobyl, which prompted a 35 percent spike in travel to the exclusion zone earlier this year. Zelensky’s administration, in addition to declaring the zone an official tourist destination, has worked to renovate paths, establish safe entry points and guidelines for visitors, and abolish the photo ban.

Invasive Snakehead Fish That Can Breathe on Land Is Roaming Georgia

A fish recently found in Georgia has wildlife officials stirred up. In fact, they’re advising anyone who sees a northern snakehead to kill it on sight.

That death sentence might sound extreme, but there’s good reason for it. The northern snakehead, which can survive for brief periods on land and breathe air, is an invasive species in North America. With one specimen found in a privately owned pond in Gwinnett County, the state wants to take swift action to make certain the fish, which is native to East Asia, doesn’t continue to spread. Non-native species can upset local ecosystems by competing with native species for food and habitat.

The Georgia Department of Natural Resources’ Wildlife Resources Division is advising people who encounter the snakehead—a long, splotchy-brown fish that can reach 3 feet in length—to kill it and freeze it, then report the catch to the agency's fisheries office.

Wildlife authorities believe snakeheads wind up in non-native areas as a result of the aquarium trade or food industry. A snakehead was recently caught in southwestern Pennsylvania. The species has been spotted in 14 states.
