New research reveals how the brain holds information in mind

Posted by in categories: biological, computing, neuroscience

MIT neuroscientists have published a key new insight on how working memory functions, in a study published in PLOS Computational Biology.

The researchers at The Picower Institute for Learning and Memory compared measurements of brain cell activity in an animal performing a working memory task with the output of various computer models representing two theories on the underlying mechanism for holding information in mind.

The results favored the newer theory that a network of neurons stores information by making short-lived changes in the connections, or synapses, between them, rather than the traditional theory that memory is maintained by neurons remaining persistently active.

If Brains are Computers, Who Designs the Software? — with Daniel Dennett

Posted by in categories: computing, education, neuroscience

Cognitive science sees the brain as a sort of computer, but how does education redesign these cerebral computers? Cognitive scientist, philosopher, and expert on consciousness Daniel Dennett explains.

Experts Warn of “Quantum Apocalypse”

Posted by in categories: computing, encryption, quantum physics

Experts are warning that quantum computers could eventually overpower conventional encryption methods, a potentially dangerous fate for humanity that they’re evocatively dubbing the “quantum apocalypse,” the BBC reports.

Cracking today’s toughest encryption would take virtually forever today — but with the advent of quantum computers, they’re warning, the process could be cut down to mere seconds.

And that kind of number-crunching power could have disastrous consequences if it were to land in the wrong hands.

Avoiding prejudices in the future world of transhumanism | Robert Anderson | TEDxFolkestone

Posted by in categories: computing, cyborgs, transhumanism

From cyborgs to the Sugababes, IT expert Robert Anderson talks about a world where the line between humans and machines becomes blurred. Drawing on his personal experiences of facing prejudices and bigotry while growing up, he shares his insight on how we can avoid repeating the mistakes of the past in order to create a society where humans and transhumans can live together in an open and equal manner. He urges us to take action now because as he says, “Transhumanism is coming and it’s coming sooner than you think. We cannot afford to have the fear of the other rule this world.“
Robert Anderson has been interested in how technology can improve humans’ lives ever since he can remember. He started programming computers at age 10 and has been working in IT for the past 20 years with blue-chip companies to develop IT strategies and roadmaps.

Robert says he likes how ‘TEDxFolkstone cares about developing a group of people who are speakers, not just about people who are doing TED talks.’

Cranking the Power on Radar Capabilities

Posted by in category: computing

DARPA looks to build on previous success in radio frequency power output with new transistor-focused THREADS program.


“Radar capabilities are essential to countless mission-critical functions, from navigation to weather-tracking to comms and more. Solving thermal challenges could unlock the power to leap ahead – that’s the goal of our new THREADS program. Details: https://www.darpa.mil/news-events/2022-11-23

You’ll Soon Be Able To Run Holograms On Your Smartphone

Posted by in categories: computing, holograms, mobile phones

I had many ideas on how to improve Twitter, and a communication paradigm was one. The iPhone changed phones, and was a device. Twitter has no device to add to its portfolio. People have no desire to add products to Twitter portfolio to boost revenues. iPhone revenue surpassed computers, therefore it is very easy for Twitter to develop its portfolio to include better more reliable forms of revenue than advertising. A device can make a lot of money if it is a “paradigm” like an iPhone that completely changed our understanding of what a phone can be.


In 1943, Thomas Watson, the president of IBM, famously predicted the world market for computers would top out at “maybe five” of the machines. He was wrong – you likely have more than that in your own house, let’s face it – but at the time, it made sense. After all, if computers were still gigantic, vacuum-tube-powered addition machines, you probably wouldn’t want more than about five either.

It’s a similar story with holograms. Even back in the 1990s, more than 40 years after Dennis Gabor first came up with the idea of using wavefront interference to reconstruct images in three dimensions, science fiction was still assuming the need for entire decks and suites to power our holographic adventures.

Nvidia’s laptop RTX 4080 obliterates its predecessor

Posted by in category: computing

As far as scores go, the laptop version of the RTX 4,080 scored 178,038 points. The Geekbench OpenCL database shows that the average score for an RTX 3,080 Ti laptop GPU is 136,008, and for an RTX 3,080 — 125,425. This means that the upcoming RTX 4,080 may be up to 30% faster than the last-gen RTX 3,080 Ti and up to 42% faster than its predecessor, the RTX 3080.

These scores certainly bode well for the mobile iteration of the RTX 4080. In its desktop version, the card is certainly powerful, but the RTX 4,090 is often a better deal due to the way these cards are priced.

Rumor has it that Nvidia will have several new products up its sleeve, set to come out early in the new year. The desktop RTX 4,070 Ti, which may just be the previously “unlaunched” RTX 4,080 12GB, is said to make an appearance. We may also learn more about upcoming laptop GPUs. Stay tuned for more news during Nvidia’s CES 2023 keynote on January 3.
