The advantage over a human brain would be what?

Perovskite solar cells already exist, but come with some disadvantages as it's brittle.

We may have just found the answer to Fermi’s Paradox

Thanks! My comment wasn’t about this particular Journal article though. I simply responded to the question about publications in general with an answer about publications in general.

>1990s in a class of materials called perovskite manganites

Isn't that the stuff used in solar panels also? Does this have application in solar too?

Try this arxiv.org link.

There is nothing new. It's all just physics. Newly discovered is much more accurate.

This news article is about a journal article published in Nature.

Here's the source.

For the people complaining about reading popular science article jargon,

Here's the link to the article in Nature.

And here's the link to the article on Arxiv.

From the article: Scientists across multiple disciplines are working to create revolutionary biocomputers where three-dimensional cultures of brain cells, called brain organoids, serve as biological hardware. They describe their roadmap for realizing this vision in the journal Frontiers in Science.

“We call this new interdisciplinary field ‘organoid intelligence’ (OI),” said Prof Thomas Hartung of Johns Hopkins University. “A community of top scientists has gathered to develop this technology, which we believe will launch a new era of fast, powerful, and efficient biocomputing.”

Brain organoids are a type of lab-grown cell-culture. Even though brain organoids aren’t ‘mini brains’, they share key aspects of brain function and structure such as neurons and other brain cells that are essential for cognitive functions like learning and memory. Also, whereas most cell cultures are flat, organoids have a three-dimensional structure. This increases the culture's cell density 1,000-fold, meaning that neurons can form many more connections.

But even if brain organoids are a good imitation of brains, why would they make good computers? After all, aren't computers smarter and faster than brains?

"While silicon-based computers are certainly better with numbers, brains are better at learning,” Hartung explained. “For example, AlphaGo [the AI that beat the world’s number one Go player in 2017] was trained on data from 160,000 games. A person would have to play five hours a day for more than 175 years to experience these many games.” 

Brains are not only superior learners, they are also more energy efficient. For instance, the amount of energy spent training AlphaGo is more than is needed to sustain an active adult for a decade.

“Brains also have an amazing capacity to store information, estimated at 2,500TB,” Hartung added. “We’re reaching the physical limits of silicon computers because we cannot pack more transistors into a tiny chip. But the brain is wired completely differently. It has about 100bn neurons linked through over 1015 connection points. It’s an enormous power difference compared to our current technology.”

His brain is also in small sections and scattered all over various research institutions and museums.

Very interesting! I was first confused because running electricity creates its own magnetic field so wouldn't running electricity through the material drop its own resistance itself?

Turns out the paper addresses that issue: yes it does, but it takes several minutes to force the current through the material. So the external magnetic field reduces that time from minutes to 0 time. There are so many ways this material could be used for cool things.

Things like that wake my evil thoughs.. like, what if we could engineer them to specifically target certain annoying individuals?

That largely depends on the Journal it’s published in. Anyone can make a website and call it a scientific Journal, accept crap (often for money) and send it out into the world. Established Journals on the other hand are much better at vetting the research, have higher standards than even they themselves used to have and generally publish high-quality studies.

In conclusion: there’s Scientific Papers and “scientific papers”. Check the source.

myes the paper is paywalled i love science

It amazes me that despite impending ecological collapse, so many people on this thread express personalized fear at this discovery than see it as a potential triumph for the animal. The personalization of fear while at the same time systemically pushing others to extinction is curious. Please contextualize your emotions.

Thank you kind human
