Thanks to a Danish physicist, the world might soon be snacking on jellyfish chips

Alongside their love of hoodies and the word “disruption,” one way to recognize techies away from their computers is through their penchant for unusual foodstuffs. Whether it’s otherworldy recipes designed by AI, 3D-printed candy, or specially engineered red algae made to look like juicy shrimp, folks in tech like their culinary experience to be as cutting edge as their smartphones. Well, move over bleedable veggie burgers, because there may soon be a new snack in town: jellyfish chips.

Developed as part of physicist Mie Thorborg Pedersen’s master’s thesis at the University of Southern Denmark, the technique offers an alternative to the salting process that’s been used in Asian cultures for centuries. It involves extracting water from the jellyfish using a combination of kitchen salt and alum. Not only is the new technique considerably faster at producing an edible snack than the traditional 30-to-40-day drying-out process, but it also results in considerably tastier food — complete with crispy texture.

“It is fascinating how you can turn a very slimy gel into a crispy chip,” Pedersen told Digital Trends. “We developed a method for preparing jellyfish for eating with inspiration from how gels behave in different solvents. When we immerse jellyfish in 96 percent ethanol we observe how the gel of the jellyfish collapse, in line with theories concerning gels. After 2 to 3 days we can then let the alcohol evaporate and get this paper-like jellyfish chip.”

The reason why the creation is so promising to Pederson and others is because it offers a potential new food source whose population has — contrary to other sources of overfished seafood — exploded in recent years. Jellyfish numbers are so great that, in some parts of the world, jellyfish-killing robots have been deployed to deal with the problem. (And it really is a problem: Nuclear power plants have been shut down as a result of swarms of jellyfish clogging up the pipes!)

“What makes this exciting is that people in the Western world are starting to look for alternative food sources such as insects, and the jellyfish is a supplement to this,” Pederson said.

A paper on the work was recently published in the International Journal of Gastronomy and Food Science.

The Apple Car may be dead, but it became the foundation of Apple Intelligence
A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.
Apple Intelligence in Apple Car

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

Researchers hid a prompt injection inside a PNG, and AI fell for it

AI coding assistants like Claude are becoming every developer's favorite coworker. They can review code, explain confusing functions, and even write entire features with a single prompt. But new research suggests that this growing trust could also become their biggest weakness.

A team of security researchers (professor Sudipta Chattopadhyay and researcher Murali Ediga) has demonstrated an unusual attack that doesn't target the AI model directly. Instead, it targets what the AI doesn't pay enough attention to during code reviews. Rather than hiding malicious instructions in lines of code, the researchers tucked them inside an image file. Since many AI review tools treat images as decorative assets rather than as something worth inspecting, the pull request can appear perfectly harmless and sail through the review.

AI has already fallen into the wrong hands and they’re using it to make bombs

Artificial intelligence has quickly become the go-to tool for everything from writing emails and summarizing meetings to helping students study or developers debug code. But the same technology that saves people time can also be misused, and a new report suggests that terrorist organizations are finding ways to do exactly that.

According to a research paper shared with The New York Times ahead of its publication, researchers found evidence that members of Boko Haram have been using popular AI chatbots to support both day-to-day activities and combat-related tasks. Interviews with 27 former members conducted in Nigeria over the past two years suggest that tools such as ChatGPT, Gemini, Claude, Grok, Meta AI, and DeepSeek were used to gather technical information, troubleshoot weapons, and even assist with planning attacks.
