Is lab-grown meat kosher? - The Economist

FOR A WHILE, it seemed everyone was going vegan. In March 2022 almost half of Britons surveyed by Ipsos, a pollster, said they were thinking of eating fewer animal products. But amid high prices and concerns over ultra-processed food, the industry is proving to be more sizzle than steak. In June Meatless Farm, a plant-based company, fell into administration. Demand for patties of rehydrated textured pea protein have flopped. “Meat alternatives don’t taste good enough,” says Max Jamilly, a co-founder of Hoxton Farms, a startup.

The “magic ingredient” is fat: the stuff that makes meat sputter, crisp and brown. So Mr Jamilly’s startup set out to make a lab-grown version of it. In a trendy East London office block, his engineers grow stem cells in a broth of plant-based food. To replicate the warm inside of a pig the cells are grown in cultivators, similar to fermenters for brewing beer. The result is animal fat without the carcass (or animal suffering), to be sold to alternative-meat companies. The target consumers are carnivores, not vegans. If fewer pigs are reared, that could be good for the planet: over three-quarters of the world’s agricultural land is used for livestock.

Would anyone pork out on lab-grown fat? Consumers may recoil at first from the Frankenstein food, versions of which are permitted, for now, only in America and Singapore. Yet people usually come around to new foods because price matters more than how the sausage is made. As long as cultivated meat must be produced with medical-grade equipment it will remain expensive. Once rules are relaxed prices should fall, as could unease about the unfamiliar. A decade ago Mark Post, a Dutch scientist, unveiled a $330,000 lab-grown burger, made of both muscle and fat. He will soon take his products to market, and has even convinced a New York rabbi to say cultivated pork could be kosher.

A New Attack Impacts ChatGPT—and No One Knows How to Stop It - WIRED

ChatGPT and its artificially intelligent siblings have been tweaked over and over to prevent troublemakers from getting them to spit out undesirable messages such as hate speech, personal information, or step-by-step instructions for building an improvised bomb. But researchers at Carnegie Mellon University last week showed that adding a simple incantation to a promptâa string text that might look like gobbledygook to you or me but which carries subtle significance to an AI model trained on huge quantities of web dataâcan defy all of these defenses in several popular chatbots at once.

The work suggests that the propensity for the cleverest AI chatbots to go off the rails isn't just a quirk that can be papered over with a few simple rules. Instead, it represents a more fundamental weakness that will complicate efforts to deploy the most advanced AI.

The researchers used an open source language model to develop what are known as adversarial attacks. This involves tweaking the prompt given to a bot so as to gradually nudge it toward breaking its shackles. They showed that the same attack worked on several popular commercial chatbots, including ChatGPT, Google's Bard, and Claude from Anthropic.

Sustainable Cities: How Urban Scandinavia Is Going Green - Forbes

Denmark's capital city features hundreds of miles of dedicated cycle paths and harbor swimming ... [+] pools.

Sustainability is more than just a buzzword in Northern Europe. Many Scandinavian cities prioritize sustainability in their urban planning, leading to eco-friendly initiatives and the protection of green spaces throughout the region, despite continued urban growth.

With that in mind, it’s no surprise to learn that all three Scandinavian capitals are among the top four ranked cities in the Arcadis Sustainable Cities Index.

What Managers Keep Getting Wrong About Generation Z - Forbes

Top researchers at universities and businesses that study the future of work say Generation Z requires a lot of mental health support, they have strong feelings about company values and they’re not shy about their work likes and dislikes. They are a lot, this group of 16- to 26-year-olds who make up 15% of the population. They will make up 30% of the workforce by 2030, which means future managers should be interested in learning more about this new breed of rebel talent. Mostly, what you read though, are complaints. Get to know what’s in their heads, how you unique their point of view is and why, and managers will see what’s going right.

What if you thought about finding joy in the way Gen Z thinks? What if you admired their ... [+] differences? Researchers say it can work wonders for managers.

The Generation Z workers I spoke with are more trailblazers than troublemakers. They are still finding their footing, for sure, but managing in unprecedented and uncertain times. Many are using uncommon solutions to solve their issues—crisis text lines, peer support groups and taking internet friends offline to organize for a cause.
