Caltech researchers create ‘self-healing’ computer chip that can fix itself

Forget about taking your failed Macbook Air to Apple Geniuses to make it all better. In the not so distant future, our computers might be able to automatically diagnose and heal themselves in microseconds with the help of “self-healing” computer chips developed by researchers at the California Institute of Technology (Caltech).

The Caltech team has built a power amplifier that can detect its own problems and look for workarounds if something fails, like if there is insufficient power to keep the computer running. As reported by Parity News, the team tested how resilient a group of 76 self-healing chips are by “zapping them with high-power lasers.” Like a lizard that can regenerate a new tail on-the-fly as it makes it escape from an enemy, the chips were able to”repair them[selves] to keep the larger system going” within a second.

While this power amplifier is by no means an organic being that can actually grow damaged parts, it is smart enough to troubleshoot itself and come up with its own solutions without interference from researchers. That’s because they have equipped the chips with sensors that monitor everything from temperature to voltage, but leave its on-board “brain” to “make decision based on the data fed to it by the sensors” so the chip can make repairs immediately.

The hope is that the Caltech researchers will be able to apply what they learned from creating this smart power-management chip to other computer parts on a motherboard. The ultimate user-friendly computer would be one that could just fix itself when say your home-brewed hybrid hard drive/SSD setup suddenly decides to fail, so you wouldn’t miss a beat. For now, you can read all about the team’s findings in their research paper.

It’s all change at Dell this year with the Dell XPS 16 replacing the Dell XPS 17 and the Dell XPS 15 gradually seeing fewer updates. That means if you’re still keen to snag a Dell XPS 15 or 17, your chance to do so is running out. That’s why it’s great to see some excellent laptop deals for both models with up to $900 to be saved at the moment. If you’re looking for a new laptop, read on while we guide you through what each laptop has to offer.
Dell XPS 17 -- $1,949, was $2,849

The Dell XPS 17 remains a good option for anyone seeking a powerful laptop that works well as a desktop replacement. It has a 13th-generation Intel Core i7-13700H processor with a massive 32GB of memory so it’s ideal for all kinds of productivity-based tasks such as if you need to manage many spreadsheets at once or if you just prefer to have a lot of windows open at once. It also has 1TB of SSD storage while it can handle plenty of gaming too thanks to its Nvidia GeForce RTX 4070 graphics card. Its display is a 17-inch full HD+ model with 1920 x 1200 resolution, anti-glare properties, and 500 nits of brightness so it looks great. Other quality of life improvements include plenty of USB-C ports, up to 14 hours of battery life, a great cooling system, and a form factor that means it squeezes a 17-inch display into a 15-inch form size. It also has a large edge-to-edge backlit keyboard, comfortable touchpad, and large keycaps so it feels good to work on as you’d expect from the makers of some of the best laptops.

Intel’s big bet on efficient GPUs might actually work
An Intel Meteor Lake processor socketed in a motherboard.

Intel has a lot riding on its next-gen Battlemage graphics architecture, and a very early benchmark shows some promising signs for performance. An Intel Lunar Lake CPU packing a low-power integrated Battlemage GPU was reportedly spotted in the SiSoftware benchmark database. It boasts not only higher performance than Intel's Meteor Lake chips, but also much better efficiency.

User @miktdt on X (formerly Twitter) spotted the result, which appears to come from an early qualification sample of the HP Spectre x360 14. The benchmark picked up that the laptop was using a Lunar Lake CPU, which is said to come with the Xe2-LPG architecture, a lower-power version of Battlemage.
