The restaurant problem reveals why human shortcuts can work surprisingly well.One day after WIRED revealed that Meta had quietly embedded an unreleased face-recognition system into an app installed on more than 50 million phones, the company removed it, according to a WIRED analysis of the latest version’s code.
The most recent version of Meta AI, a companion app for its line of smart glasses, strips out the unactivated software components that powered the system Meta internally called NameTag. The version published the day of WIRED’s report included several code libraries explicitly named for face recognition. Friday’s release includes none of them.
Andy Stone, Meta's vice president of communications, told WIRED on Monday that the feature is purely exploratory, adding: “No final decision has been made on what to do here, if anything.”

Despite having tiny brains, bumblebees have demonstrated a remarkable ability to socially learn how to use tools, solve simple puzzles, and cooperate to achieve a goal. It seems they can also solve object-manipulation tasks without any previous training, according to a new paper published in the journal Science. According to the authors, it's the first time this kind of spontaneous problem-solving has been demonstrated in an insect.
In 2024, Olli Loukola of the University of Finland co-authored a study demonstrating that bumblebees could cooperate to solve complex challenges. It's the kind of cognitive task scientists had previously only observed in large-brained mammals like humans and chimpanzees. Loukola et al. trained pairs of bees to push a Lego block to the middle of a mini-arena or push against a door at the end of a tunnel to get a reward.
The team noticed that the bees were more likely to engage in the tasks if their partners also participated, compared to untrained control groups. They concluded that bees can learn to solve novel cooperative tasks outside the hive and may even be intentionally working together, although the researchers cautioned that more detailed monitoring of the behavior was needed to fully understand the partners' roles.

A simple writing task may offer clues about aging brains. Researchers found that dictation, in particular, exposed subtle differences linked to cognitive impairment. Handwriting depends on both fine motor skills and complex mental processes, including selecting, organizing, and interpreting sensory information. Because writing places heavy demands on the brain, changes in handwriting may help reveal [...]In hours of underwater video footage from a New York aquarium, a beluga whale named Natasha stretches her neck, pirouettes, nods, and shakes her head in front of a two-way mirror. Her daughter Maris does much the same. According to a new study published in PLOS One, both animals show the behavioral hallmarks of mirror self-recognition—a cognitive ability long considered a marker of self-awareness, and one that had never before been documented in beluga whales.
If the result holds up, belugas join a remarkably short list. The mirror self-recognition test (MSR) has been passed, with varying degrees of confidence, by humans (starting around age two), a handful of great apes (chimps, bonobos, orangutans, and—somewhat contentiously—gorillas), Asian elephants, bottlenose dolphins, probably magpies, possibly orcas, and, if you can believe it, a cleaner wrasse. That's it. No dogs, no cats, no monkeys. Plenty of species we had assumed were self-aware have been tested and failed.
So what is this test, exactly, and what is it supposed to tell us?
