MRI scans and AI to decode what we think? This study has answers

Posted by in categories: biotech/medical, neuroscience, robotics/AI

Is mind reading possible? An age-old question with multiple unproven answers. Those who study psychology often claim that they can understand what the other person is saying as they study mental processes, brain functions, and behaviour, but even they can be 100 per cent accurate.

A study, published in the journal Nature Neuroscience, attempts to address it as scientists have said that they have come up with a way to decode a stream of words in the brain using MRI scans and artificial intelligence.

The study titled — “Semantic reconstruction of continuous language from non-invasive brain recordings” — noted that the system won’t replicate each word but it reconstructs the brief of what a person hears or imagines. The study was published in the journal Nature Neuroscience.

Turning Your Smartphone into a Quantum Sensor: The Power of OLEDs

Posted by in categories: biotech/medical, computing, mobile phones, quantum physics

UNSW Sydney researchers have developed a chip-scale method using OLEDs to image magnetic fields, potentially transforming smartphones into portable quantum sensors. The technique is more scalable and doesn’t require laser input, making the device smaller and mass-producible. The technology could be used in remote medical diagnostics and material defect identification.

Smartphones could one day become portable quantum sensors thanks to a new chip-scale approach that uses organic light-emitting diodes (OLEDs) to image magnetic fields.

Researchers from the ARC Centre of Excellence in Exciton Science at UNSW Sydney have demonstrated that OLEDs, a type of semiconductor material commonly found in flat-screen televisions, smartphone screens, and other digital displays, can be used to map magnetic fields using magnetic resonance.

Quantum Ghosts: Atoms Become Transparent to Certain Frequencies of Light

Posted by in categories: particle physics, quantum physics

Researchers at Caltech have discovered a new phenomenon, “collectively induced transparency” (CIT), where light passes unimpeded through groups of atoms at certain frequencies. This finding could potentially improve quantum memory systems.

A newly discovered phenomenon dubbed “collectively induced transparency” (CIT) causes groups of atoms to abruptly stop reflecting light at specific frequencies.

CIT was discovered by confining ytterbium atoms inside an optical cavity—essentially, a tiny box for light—and blasting them with a laser. Although the laser’s light will bounce off the atoms up to a point, as the frequency of the light is adjusted, a transparency window appears in which the light simply passes through the cavity unimpeded.

Deep learning pioneer Geoffrey Hinton warns against rapid AI development as he quits Google

Posted by in category: robotics/AI

Geoffrey Hinton who won the ‘Nobel Prize of computing’ for his trailblazing work on neural networks is now free to speak about the risks of AI.

Man often dubbed the ‘Godfather of AI’ says part of him now regrets his life’s work.

One of the pioneers in the development of deep learning models that have become the basis for tools like ChatGPT and Bard, has quit Google to warn against the dangers of scaling AI technology too fast.

Drake’s AI clone is here — and Drake might not be able to stop him

Posted by in categories: law, media & arts, robotics/AI

Major record labels are going after AI-generated songs, arguing copyright infringement. Legal experts say the approach is far from straightforward.

A certain type of music has been inescapable on TikTok in recent weeks: clips of famous musicians covering other artists’ songs, with combinations that read like someone hit the randomizer button. There’s Drake covering singer-songwriter Colbie Caillat, Michael Jackson covering The Weeknd, and Pop Smoke covering Ice Spice’s “In Ha Mood.” The artists don’t actually perform the songs — they’re all generated using artificial intelligence tools. And the resulting videos have racked up tens of millions of views.

Elon Musk says he’s getting rid of rare Earth magnets in Tesla EVs

Posted by in categories: business, Elon Musk, sustainability, transportation

In a recent presentation, Tesla said that it was working to eliminate rare Earth magnets from its EVs over supply and toxicity concerns.

In a major move, Tesla is looking to rid its electric vehicles of rare Earth minerals, potentially eliminating the biggest environmental concern over the increasing number of EVs on the road.

The surprise announcement came during Tesla’s Master Plan 3 Investor event where the company outlined its business strategy for the next few years.

OpenAI wants to shut a student’s repository over GPT4 access

Posted by in category: robotics/AI

Xtekky, a European computer science student, finds out what happens if you write a program that runs queries through these freely accessible sites and returns you the answer.

In other news, a big company with a non-profit and for-profit subsidiary sues an independent creator trying to make things easier for everyday folks. Even though it technically doesn’t violate its terms and conditions? Perhaps we’ll leave that for the experts to decide.

OpenAI, the creators of ChatGPT, a scourge on teachers and succor to everyone else, opted against free access when it released its newer GPT4 model.
