The piano-mover puzzle involves trying to transport an oddly shaped load across a constricted environment with various obstructions. It's one of several variations on classic computational motion-planning problems, a key element in numerous robotics applications. But what would happen if you pitted human beings against ants in a competition to solve the piano-mover puzzle?

According to a paper published in the Proceedings of the National Academy of Sciences, humans have superior cognitive abilities and, hence, would be expected to outperform the ants. However, depriving people of verbal or nonverbal communication can level the playing field, with ants performing better in some trials. And while ants improved their cognitive performance when acting collectively as a group, the same did not hold true for humans.

Co-author Ofer Feinerman of the Weizmann Institute of Science and colleagues saw an opportunity to use the piano-mover puzzle to shed light on group decision-making, as well as the question of whether it is better to cooperate as a group or maintain individuality. "It allows us to compare problem-solving skills and performances across group sizes and down to a single individual and also enables a comparison of collective problem-solving across species," the authors wrote.

Lenovo announced a laptop today that experiments with a new way to offer laptop users more screen space than the typical clamshell design. The Lenovo ThinkBook Plus Gen 6 Rollable has a screen that can roll up vertically to expand from 14 inches diagonally to 16.7 inches, presenting an alternative to prior foldable-screen and dual-screen laptops.

The laptop, which Lenovo says is coming out in June, builds on a concept that Lenovo demoed in February 2023. That prototype had a Sharp-made panel that initially measured 12.7 inches but could unroll to present a total screen size of 15.3 inches. Lenovo's final product is working with a bigger display from Samsung Display, The Verge reported. Resolution-wise you're going from 2,000×1,600 pixels (about 183 pixels per inch) to 2,000×2,350 (184.8 ppi), the publication said.

Users make the screen expand by pressing a dedicated button on the keyboard or by making a hand gesture at the PC's webcam. Expansion entails about 10 seconds of loud whirring from the laptop’s motors. Lenovo executives told The Verge that the laptop was rated for at least 20,000 rolls up and down and 30,000 hinge openings and closings.

Meta announced today that it's ending the third-party fact-checking program it introduced in 2016, and will rely instead on a Community Notes approach similar to what's used on Elon Musk's X platform.

The end of third-party fact-checking and related changes to Meta policies could help the company make friends in the Trump administration and in governments of conservative-leaning states that have tried to impose legal limits on content moderation. The operator of Facebook and Instagram announced the changes in a blog post and a video message recorded by CEO Mark Zuckerberg.

"Governments and legacy media have pushed to censor more and more. A lot of this is clearly political," Zuckerberg said. He said the recent elections "feel like a cultural tipping point toward once again prioritizing speech."
