A new state of the art for unsupervised computer vision

With the STEGO algorithm, research scientists attempted to solve a massive labeling problem plaguing vision models. STEGO can jointly discover and segment objects without any human labels at all, down to the pixel. Credits:Image courtesy of MIT CSAIL.

MIT CSAIL scientists created an algorithm to solve one of the hardest tasks in computer vision: assigning a label to every pixel in the world, without human supervision.

A good deal of web3 security rests on blockchains’ special ability to make commitments and to be resilient to human intervention. But the related feature of finality – where transactions are generally irreversible – makes these software-controlled networks a tempting target for attackers. Indeed, as blockchains – the distributed computer networks that are the foundation of web3 – and their accompanying technologies and applications accrue value, they become increasingly coveted targets for attackers.

Tesla Takes A 9400 Mile, Solar-Powered Road Trip
By | CleanTechnica

A team of scientists from Australia and the UK are embarking on an epic, 9400-mile Tesla road trip across some of the most remote regions of the world– and they’re doing it on 100% solar power.

The project is called “Charge Around Australia,” and the team hopes to get Aussies to think about new ways to prevent climate change while showing off the range and flexibility of the electric Tesla sedan.

🌙 NASA - Best Photo from Last Week
Happy 32nd Birthday to Hubble!

We're celebrating the Hubble Space Telescope's 32nd birthday with a stunning look at an unusual close-knit collection of five galaxies, called The Hickson Compact Group 40.

This eclectic galaxy grouping includes three spiral-shaped galaxies, an elliptical galaxy, and a lenticular (lens-like) galaxy. Somehow, these different galaxies crossed paths in their evolution to create an exceptionally crowded and eclectic galaxy sampler.
