This enormous air purifier sucks smog from the air, turns it into cubes

Add as a preferred source on Google

After visiting Beijing and experiencing the effects of smog first hand, the folks at Studio Roosegaarde were inspired to do something about this form of air pollution. For three years, the team worked on an indoor smog remover prototype, and now they are ready to take the project to next level. Led by Daan Roosegaarde, Studio Roosegaarde is raising funds on Kickstarter to fund the creation of the Smog Free Tower, the world’s largest outdoor air purifier.

The Smog Free Tower will be built in Rotterdam, the Netherlands and will be travel around the world visiting cities where air pollution is a known problem. Powered now by wind power and possibly solar in the future, the tower will provide residents of these metropolitan areas with a small zone of very clean air that they can enjoy. The air in these “Smog Free Parks” is 75% cleaner than the polluted air in the rest of the city. By experiencing fresh, clean air, Studio Roosegaarde hopes to raise awareness about the problem of smog.

The Smog Free Tower is designed to be a zero wastes machine recycling the collected smog particles in Smog Free Cubes. The tower used patented ion technology that’ll remove the smog particles from the air. As a tangible reminder of smog, the Tower each day will collect and compress enough smog particles to form 3500 Smog Free Cubes. These cubes will be harvested and turned into a piece of jewelry, such as a ring or cufflinks. With enough time and pressure, the carbon in the dust can even be turned into a diamond.

The Smog Free Tower Kickstarter project is in its final week of fundraising, thus far accruing 971 backers who have pledged more than $83,000 towards the project. Those who have supported the project can receive a Smog Free Cube, a Smog Free Ring and other swag depending on the chosen funding level.

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
Hacker

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.
