Pocket-Sized AI Models Could Unlock a New Era of Computing Will Knight | Wired When ChatGPT was released in November 2023, it could only be accessed through the cloud because the model behind it was downright enormous. Today I am running a similarly capable AI program on a Macbook Air, and it isnt even warm. The shrinkage shows how rapidly researchers are refining AI models to make them leaner and more efficient. It also shows how going to ever larger scales isnt the only way to make machines significantly smarter.

Google Promised a Better Search ExperienceNow Its Telling Us to Put Glue on Our Pizza Kylie Robison | The Verge This is just one of many mistakes cropping up in the new feature that Google rolled out broadly this month. It also claims that former US President James Madison graduated from the University of Wisconsinnot once but 21 times,that a dog has played in the NBA, NFL, and NHL, and thatBatman is a cop. Look, Google didnt promise this would be perfect, and it even slaps a Generative AI is experimental label at the bottom of the AI answers. But its clear these tools arent ready to accurately provide information at scale.

Gene Therapy Repairs Spinal Discs to Relieve Back Pain Michael Irving | New Atlas Assessed over 12 weeks, injured mice that received the gene therapy were found to have a host of improvements compared to injured mice given plain saline injections. The tissue in the discs was found to produce more proteins that strengthen the tissue, and help it hold water. That helped them plump back up and act more like cushions again, improving the spines range of motion, load bearing and flexibility. While you cant exactly ask mice how much pain theyre feeling, behavioral tests suggested symptoms were reduced.

On Self-Driving, Waymo Is Playing Chess While Tesla Plays Checkers Timothy B. Lee | Ars Technica Many Tesla fans see [limitations like remote operators and avoiding freeways] as signs that Waymo is headed for a technological dead end. But I predict that when Tesla begins its driverless transition, it will realize that safety requires a Waymo-style incremental rollout. So Tesla hasnt found a different, better way to bring driverless technology to market. Waymo is just so far ahead that its dealing with challenges Tesla hasnt even started thinking about. Waymo is playing chess while Tesla is still playing checkers.

A Warp Drive Breakthrough Inches a Tiny Bit Closer toStar Trek Paul Sutter | Wired A team of physicists has discovered that its possible to build a real, actual,physical warp driveand not break any known rules ofphysics. One caveat: The vessel doing the warping cant exceed the speed of light, so youre not going to get anywhere interesting anytime soon. But this research still represents an important advance in our understanding ofgravity.

Media Companies Are Making a Huge Mistake With AI Jessica Lessin | The Atlantic For as long as I have reported on internet companies, I have watched news leaders try to bend their businesses to the will of Apple, Google, Meta, and more. Chasing techs distribution and cash, news firms strike deals to try to ride out the next digital wave. They make concessions to platforms that attempt to take all of the audience (and trust) that great journalism attracts, without ever having to do the complicated and expensive work of the journalism itself. And it never, ever works as planned.

ChatGPT, Explained Sheena Vasani | The Verge Some writers have declared thatthe debutof ChatGPT on November 30th, 2022, marked the beginning of a new chapter in history akin to theEnlightenmentand theIndustrial Revolution.Others have been more skeptical, wondering if this is just another overhyped tech, likeblockchainor themetaverse. What history will call ChatGPT remains to be seen, but heres one thing I do know for sure: nobody has shut up about it since. Thats why we decided to throw together this explainer so we can cut through all the BS together. You ready?Lets begin.

OpenAI Should Have Gone Way Beyond Scarlett Johansson Ross Andersen | The Atlantic Now that we can actually talk with a computer, we should be dreaming up wholly new ways to do it. Lets hope that someoneinside or outside of OpenAIstarts giving us a sense of what those ways might be. The weirder, the better. They may not even be modeled after existing human relationships. They may take on entirely different forms.

This Week's Awesome Tech Stories From Around the Web (Through May 25) - Singularity Hub

Melanie Reid was 52 years old when she hopped onto her horse, fell, and broke her neck. The resulting injury paralyzed her body below the chest area. Fourteen years later and after extensive physical therapy, she has gradually regained some function in her right handa lifeline, she said in a press conference. But her left hand remained useless.

As a journalist, the injury was devasting as she couldnt type. Even seemingly simple everyday routinestying her hair up into a ponytail, using an ATM card, or even unwrapping candywere a struggle.

With the help of a new device, shes able to do all that after just two months of use. Called ARC-EX therapy, the device zaps residual neural connections around the site of spinal cord injuries. Combined with physical rehabilitation, the treatment restored some functionality in her left handeven when the stimulation was turned off.

Reid was part of a 60-participant clinical trial that looked to use spinal cord stimulation to regain control of both hands. Similar treatments have shown promise in paraplegic patients, restoring the ability to walk in just a day. But those required surgery to place electrodes on the spinal cord.

ARC-EX therapy, by contrast, delivers two different types of electrical pulses through the skinno surgery required. Developed by Grgoire Courtine and colleagues at the Swiss Federal Institute of Technology, the device improved hand strength, pinch, and other movements in 72 percent of participants.

Because the device is non-invasive, its a simple addition to physical rehabilitation programsa sort of pilates for the fingers, explained the team. The trial only included two months of stimulation, and extending the timeline could potentially further improve results.

The stimulation only helps with finger and hand dexterity, not walking. But to Reid, thats what matters. Everyone thinks that [with] spinal injury all you want to do is to be able to walk again, she said. But what matters most is working hands[and] the gains can be life-changing.

All participants in the trial had a fracture in their spinal cord, roughly at the level of the neck.

With torn nerves, the brain can no longer command the body. Like a broken phone line, when you think move your hand, the signal gets lost at the break. Scientists have long tried to bridge this communication gap with electrodes to control muscle movement, essentially replacing broken biological wires with artificial ones.

Spinal cord stimulation is one solution. In 2018, a man walked across an entire football field years after he was paralyzed thanks to zaps to his spinal cord. With just a days stimulation, people with complete paralysis have been able to stroll around a busy downtown and go kayaking.

The key to recovery, explained the team, is to target living nerves. In a majority of cases, even patients deemed to have a complete spinal cord injury still have nerves left, and stimulating them can trigger regrowth and connections.

Picture the spinal cord as a tree, with branches reaching towards the skin. Now, imagine if the trunk was partially severed. By zapping the skin around the injury site, its possible to transmit electrical signals to the injured spinal cord trunk and allow living neurons near the injury site to rebuild neural connections.

In preclinical models, when applying stimulation, we immediately facilitated movement, said Courtine. But even more importantly, we saw new neuron growth, as if the body was repairing the broken neural system, he added. With sufficient healing, patients could potentially be able to use their hands even without stimulation.

Based on these ideas, the team built the ARC-EX device.

The clinical trial included 60 people with neck-level spinal cord injury. All participants underwent two months of physical therapy, followed by another two months of physical therapy combined with ARC-EX stimulation. The group was roughly 46 years old on average.

For physical rehab, each person practiced movements such as pinching, grasping, or moving the whole arm for an hour each day, up to five times a week. Although the therapy improved arm and hand function, progress plateaued for most patients.

The team then added ARC-EX stimulation, with the electrodes placed above and below the site of injury. During therapy, the team controlled the frequency and strength of the zaps, so it facilitated arm and hand movements without causing any unwanted muscle jerking.

The trial was open label, meaning both participants and researchers know theyre receiving stimulation. This can be risky business because of the placebo effectwhen participants recover because they think theyre getting the actual treatment, rather than, say, sham stimulation. However, with ARC-EX its impossible to blind the stimulation. Turning the device on immediately causes strange sensations in the participants, with the electrical pulses feeling like a sort of a buzz, said Reid. Turning the device off also immediately alerted participants. In one example, Reid said she was holding a jar with weights with the stimulation on, but with the stimulation offunbeknownst to hershe immediately dropped the jar.

In just eight weeks, 72 percent of participants met or exceeded goals for hand strength and dexteritythe ability to grab a mug or pinch a tweezeras assessed with a battery of tests. Only one person experienced unintended effectsuncontrollable muscle spasms. However, because stimulation was off when they occurred, the team says its likely not related to ARC-EX.

The therapy didnt just improve hand function. The paralyzed participants also felt less pain, had fewer struggles with breathing, and slept better.

The stimulation wont work for the roughly 10 percent of people with spinal cord injuries that completely severed all neural connections. But for those who still have residual nerve endings, it makes restoring finger movements easier.

Sherown Campbell, another participant in the trial, said ARC-EX is a life-changer. A self-proclaimed tech geek, he constantly works on his computer. Focusing on hand function was the biggest thing I was hoping to improve, he said.

With ARC-EX therapy, his typing speed increased from 25 words per minute to 33 words per minute, about a 30 percent increase, which is really significant for me, he said. But more importantly, his quality of life improved. He can cook and write againtwo seemingly simple everyday activities that give him joy but were robbed by his accident.

With the success of this trial, the device may hit the market soon. Because its non-invasive, it can easily be integrated into existing physical therapy sessions. The team is already looking for approval in the United States, with discussions with the European Union soon to follow. For now, the price is unknown, although Courtine said the aim is to make it widely accessible.

To Reid, being able to use her left hand is an enormous change to her life. Its extraordinary, she said. It makes you hold your head up and look at the world differently.

This Device Zaps the Spinal Cord to Give Paralyzed People Use of Their Hands Again - Singularity Hub

This column was originally going to be a recap of some of the technology I saw on display at NAB Show 2024 earlier this month. But as Ive been spending much of my free time since returning helping to care for my mother as she recovers from surgery, Ive also been thinking a bit more about the over-arching concept driving much of the technological innovation in the radio space right now.

For those that have never been to NAB, it is multiple events in one. There is the show floor, theres the engineering conferences, the sales conferences, the executive meetings, plus other events piggybacking on it such as Broadcast Education Association. Really it has something for every facet of the broadcast community, except for audio content creators, but even there was an attempt at improving those events this year.

What did generate much of my attention was a number of new or recently emerging players into the radio broadcast tech sphere especially on the end-user side. New cloud based playout systems, embedding of AI tech, and the moving of the playout tech from the studio to the transmitter site were seen across the floor of the show.

We are headed towards one do-all application/appliance for broadcasting. Super Hi-Fis partnership with Orban to place programming, processing, PPM encoding, stream encoding, and metadata in one box is just the start. Soon all of those features could be included in a transmitter along with access to cloud based music scheduling and voicetracking allowing one device to power nearly all of a radio stations necessary functions.

Other companies are doing the same. From Radio.cloud to internal systems like iHeartMedias Sound+, the shift to an all-in one combination of application and appliance is only going to continue. It will lead to an improved product as workflows are simplified to allow access to all relevant content in one place. AI generated auto-segueing of songs is already happening. Over time these platforms and others will include your board/faders, allow for any audio clip or song needed to be dropped in on the fly, auto-produce podcasts and on-demand audio clips and publish them to the station website, and allow for customization on the fly in ways that would still take hours of production time today.

These are the AI capabilities that radio can and should get behind as it will enable talent to better utilize their time and resources. While still being used as a novelty more than anything at this point, it is the continued growth of AI voices in on-air shifts that still is worrisome, but the fact it has not caught on in a major use is still a good sign for human voices.

But it will also enable simplicity.

One of the other major topics of discussion at and around NAB was in regards to how stations are going to solve the looming engineering crisis. Many operators, including those in larger markets such as Las Vegas, are down to relying on over-worked contract engineers at or nearing retirement age. A CEO asked us point-blank, What do I have to do to train and retain a single engineer? Having less technology to have to maintain will be a great start, especially since training will become easier. There will always be a demand for RF engineers, but radio needs to find IT capable people for studios and a combined infrastructure will make that much easier in helping to teach and learn broadcast IT.

The ability for future innovation built around a broadcast architecture that encompasses everything will only accelerate. Were already at the point where talent can broadcast from anywhere in the world just by clicking an icon in an app. Soon it may also provide web and social media content on the fly, podcasts published within seconds of content airing live, and dynamic customized broadcasts specifically for each listener truly making radio a one to one service in addition to the one to many offering it has always provided. A singular hardware/software solution creating a truly singular proposition.

Daniel Dennett: Why Civilization Is More Fragile Than We Realized Tom Chatfield | BBC [Dennetts]warning was not of a takeover by some superintelligence, but of a threat he believed that nonetheless could be existential for civilization, rooted in the vulnerabilities of human nature. If we turn this wonderful technology we have for knowledge into a weapon for disinformation, he told me, we are in deep trouble. Why? Because we wont know what we know, and we wont know who to trust, and we wont know whether were informed or misinformed. We may become either paranoid and hyper-skeptical, or just apathetic and unmoved. Both of those are very dangerous avenues. And theyre upon us.'

By contrast, Starship is designed to carry 100 tons, or more, to the lunar surface in a single mission. This is an insane amount of cargo relative to anything in spaceflight history, but thats the future that [Jaret] Matthews is aiming toward.

This Week's Awesome Tech Stories From Around the Web (Through April 27) - Singularity Hub

Emmy-winning composer and musician Bear McCreary has recruited Slash and Joe Satriani for his new single Escape from the Machines, which premiered today exclusively on Guitar World.

The two electric guitar heavyweights have joined McCreary for the latest preview of his epic, mysterious, and furious conceptual rock album, The Singularity, which arrives digitally on May 3.

McCreary describes The Singularity as an expression of my complete creative self, and calls it the result of three decades of exploring narrative, symphonic cinematic scoring, and hard rock that melds everything I love about music, storytelling and art.

Escape from the Machines is a song he first wrote when he was teenager. Now, its finally been released with the help of two of McCrearys biggest heroes.

"I wrote this song when I was 15, McCreary tells Guitar World, and never would have dared dream that one day I would hear it performed by two of the guitar gods who inspired it."

The single is as epic and operatic as youd expect from a rock concept record featuring Slash and Satriani, largely in part thanks to Satchs spectrum-sweeping solo that his fellow guest guitarist describes as super-intense.

Even that is something of an understatement: that mind-melting lead line at 1:40 performed while Slash holds down the riff is absolutely wild. The final 30 seconds is equally awe-inspiring, loaded with wild bombastic bends that wouldnt sound out of place in the climax of a Christopher Nolan epic.

All the latest guitar news, interviews, lessons, reviews, deals and more, direct to your inbox!

Of his own contributions, Satriani tells Guitar World, I loved playing on this killer track! It inspired me to be hyper-dramatic to match the power and intensity of the song.

This is my fourth appearance alongside the always-iconic Slash, he goes on. Oddly enough, we never get to hear each others contributions until the tracks are released!

Interestingly, McCreary revealed the original 30-year-old cassette demo makes a cameo on the record, before Slash reinvigorates it with a new interpretation.

"This is another great composition from a record loaded with great compositions from Bear, Slash notes. This riff was right up my alley. But some of the syncopated melodies I got to play throughout the track are pure genius McCreary.

As well as Slash and Satch, The Singularity features a huge range of additional guest stars, including Serj Tankian, Corey Taylor, Jens Kidman, Buck Dharma, Kim Thayil, Scott Ian and more.

It will be the latest release from McCreary, whose resume includes scoring work on Battlestar Galactica, The Walking Dead and The Lord of the Rings: The Rings of Power.

McCreary will share the stage with Slash and Buck Dharma and a handful of other guest musicians on May 12 at The Fonda Theatre in Los Angeles for a live performance of The Singularity Live. Tickets for the show are available now.
