New LI-RAM uses light instead of electricity to move information faster

The hunt for new and improved technologies never ceases, which is a good thing for the future of computing. As long as our hunger for faster and more powerful PCs continues, then it appears that researchers are up to the task of the continued advancements that we demand.

One area where work continues unabated is in the quest for new and faster memory, where mundane electronic technologies remain at the heart of even the fastest random-access memory (RAM). Researchers at the University of Victoria in British Columbia, Canada, hope to change all of that with their development of a new material that could make RAM perform faster and more efficiently.

The material is dubbed light-induced magnetoresistive RAM (LI-RAM), and it essentially “allows computer chips to exist at a molecular level,” as the university’s blog describes it. Chemist Natia Frank is behind the effort, which aims to reduce the power consumed and heat produced by modern PC processors — to break through the “power wall,” as it is called.

LI-RAM utilizes 10 percent less power than current RAM, produces virtually no heat, and is more durable. On top of all that, it is also faster. What makes LI-RAM special is that it uses light rather than electricity to move information around a system.

As Frank puts it, “The material in LI-RAM has the unusual quality of rapidly changing magnetic properties when hit with green light.” Information is processed and stored on single molecules, making once hypothetical “universal memory” technology possible.

According to the researchers, about 10 percent of all electricity is consumed by information communications technology, while discarded ewaste amounts to 3 million tons of hazardous materials on a global scale. LI-RAM would help alleviate some of those concerns by utilizing less power and lasting longer.

Researchers plan to use the LI-RAM for more than just mobile phones, PCs, and consumer electronics. As Frank explains, “Potentially, this material could have other uses in medical imaging, solar cells and a range of nanotechnologies. This is just the beginning.” It’s anticipated that the technology could make its way into consumer products within the next decade and it is already in the hands of international electronics manufacturers with just that goal in mind.

New Mac Studio release date, price and everything you need to know
Apple Mac Studio with M4 Max and M3 Ultra chips and two Apple Studio Display monitors.

The Apple Mac Studio has always packed a ton of power into a very diminutive block of what feels a lot like solid aluminum. It's designed to look like it's floating in air, and the majority of its ports are in the back and out of the way. There's simply no other desktop machine that takes up so little space and, frankly, looks so great on your desk.

The new model maintains all the best characteristics that makes it one of the best desktops while dramatically increasing the power. The previous generation hadn't yet received the faster GPU and Neural Engine performance, and that's now on tap. It's more expensive than ever, but if you need it, then it looks like it will deliver.
Release date and price
The new Mac Studio was announced on March 5, 2025, and will be available starting on March 12, 2025. That's earlier than many predictions, and very soon after its announcement.

The new Mac Studio absolutely baffles me in one key way
Apple Mac Studio with M4 Max and M3 Ultra chips and two Apple Studio Display monitors.

Way back when Steve Jobs returned to Apple and saved it from bankruptcy, he implemented his famous product quadrant: Apple should have desktops and laptops for consumers and professionals. These four categories should contain just one of the best Macs each -- no more, no less.

The idea was that you should be able to instantly differentiate each device and know who it’s for and what it does, and it worked incredibly effectively. Yet when I look at the new Mac Studio that Apple unveiled today, I get the feeling that Steve Jobs would be most displeased.

Google AI Mode will reinvent Search. I’m worried — and you should be, too
Google AI Mode for Search.

Google is pushing forward with more AI into how internet search works. Remember AI Overviews, which essentially summarizes the content pulled from websites, and presents it at the top of the Google Search page?

That error-prone feature is now expanding to the US market, powered by the new Gemini 2.0 AI models. It no longer requires a Google account sign-in, and has opened to users across all age groups. While that is a risky move in itself, Google is giving a similar blanket treatment to the whole Search page with a new AI Mode.
