Researchers use rat brains to predict the weather

The progression of technology is a funny thing. While certain advances are easy to anticipate ahead of time, there will always be researchers out there developing projects that few would ever even consider. A group of scientists at Duke University have set out to answer a question that no one was really asking: is it possible to create a computer from rat brains?

Before that gives anyone the wrong idea, the brains were still in the rats’ heads for the duration of the experiment — they were connected to one another via microwire arrays, rather than simply being scooped out and placed in a desktop tower. From there, they made up something the researchers are calling a ‘Brainet,’ which is described as a network of animal brains exchanging information via brain-to-brain interfaces.

While the science of connecting animal brains together to perform computational tasks is rather difficult to get your head around, the results are easier to make sense of. The rats working in league were said to have “consistently outperformed individual rats.” The researchers demonstrated this through a variety of tasks including the transfer of visual information to the Brainet, the transfer of memories between rats, and collective weather forecasting.

In the last experiment, the rats were stimulated by temperature and barometric pressure data that might indicate precipitation. Together, the rats were able to correctly forecast the weather in about 41 percent of cases — much higher than pure chance, which would result in only 16 percent accuracy.

This study follows earlier research carried out into Brainets at Duke University, but it’s an early step in a long process. The end point, at least theoretically, is the construction of organic computer systems much more powerful than the tech we have available at present — but that’s rather a long way off.

However, it could well become a reality at some point, given that this early research into the subject has proven to be a success. Perhaps in the future, your pets and your PC will be one and the same. But, for now, be thankful that you don’t have to take your laptop for a walk.

If you’re looking for great gaming laptop deals, check out what Razer has to offer. Right now you can buy the Razer Blade 15 with some great hardware, all for $1,800 instead of $2,800. The $1,000 discount is unlikely to stick around for very long, so we’re here to take a quick look at what it offers before you commit to the buy button below.

Why you should buy the Razer Blade 15
Razer is one of the best gaming laptop brands out there, sort of the MacBook of gaming laptops because of their stylish design and speedy hardware. Even the keyboard is great, and the Razer Blade 15 has a massive trackpad which is great for portable gaming. That means Razer laptops can be expensive, but that’s less of an issue when they’re on sale.

Google’s new AI generates audio soundtracks from pixels
An AI generated wolf howling

Deep Mind showed off the latest results from its generative AI video-to-audio research on Tuesday. It's a novel system that combines what it sees on-screen with the user's written prompt to create synced audio soundscapes for a given video clip.

The V2A AI can be paired with vide -generation models like Veo, Deep Mind's generative audio team wrote in a blog post, and can create soundtracks, sound effects, and even dialogue for the on-screen action. What's more, Deep Mind claims that its new system can generate "an unlimited number of soundtracks for any video input" by tuning the model with positive and negative prompts that encourage or discourage the use of a particular sound, respectively.

The Vision Pro 2 may already be dead
Apple Vision Pro

According to reports from The Information, Apple is working on a cheaper non-Pro version of the Vision Pro headset -- and hitting pause on the development of the next high-end model. These rumors come from people involved with the supply chain and manufacturing of the Vision Pro, who claim that Apple has told at least one supplier that it's stopping work on the next Vision Pro.

Just like any other Apple product with "Pro" in its name, the Vision Pro was always meant to be part of a lineup of multiple models, so it's not too much of a surprise that a cheaper model is in the works. What is surprising, however, is that there may not be a second generation of the Vision Pro released alongside it -- at least not anytime soon.
