AI Can Now Generate Entire Songs on Demand. What Does This Mean for Music as We Know It?

Singularity HUB - 7 Květen, 2024 - 19:28

In March, we saw the launch of a “ChatGPT for music” called Suno, which uses generative AI to produce realistic songs on demand from short text prompts. A few weeks later, a similar competitor—Udioarrived on the scene.

I’ve been working with various creative computational tools for the past 15 years, both as a researcher and a producer, and the recent pace of change has floored me. As I’ve argued elsewhere, the view that AI systems will never make “real” music like humans do should be understood more as a claim about social context than technical capability.

The argument “sure, it can make expressive, complex-structured, natural-sounding, virtuosic, original music which can stir human emotions, but AI can’t make proper music” can easily begin to sound like something from a Monty Python sketch.

After playing with Suno and Udio, I’ve been thinking about what it is exactly they change—and what they might mean not only for the way professionals and amateur artists create music, but the way all of us consume it.

Expressing Emotion Without Feeling It

Generating audio from text prompts in itself is nothing new. However, Suno and Udio have made an obvious development: from a simple text prompt, they generate song lyrics (using a ChatGPT-like text generator), feed them into a generative voice model, and integrate the “vocals” with generated music to produce a coherent song segment.

This integration is a small but remarkable feat. The systems are very good at making up coherent songs that sound expressively “sung” (there I go anthropomorphizing).

The effect can be uncanny. I know it’s AI, but the voice can still cut through with emotional impact. When the music performs a perfectly executed end-of-bar pirouette into a new section, my brain gets some of those little sparks of pattern-processing joy that I might get listening to a great band.

To me this highlights something sometimes missed about musical expression: AI doesn’t need to experience emotions and life events to successfully express them in music that resonates with people.

Music as an Everyday Language

Like other generative AI products, Suno and Udio were trained on vast amounts of existing work by real humans—and there is much debate about those humans’ intellectual property rights.

Nevertheless, these tools may mark the dawn of mainstream AI music culture. They offer new forms of musical engagement that people will just want to use, to explore, to play with, and actually listen to for their own enjoyment.

AI capable of “end-to-end” music creation is arguably not technology for makers of music, but for consumers of music. For now it remains unclear whether users of Udio and Suno are creators or consumers—or whether the distinction is even useful.

A long-observed phenomenon in creative technologies is that as something becomes easier and cheaper to produce, it is used for more casual expression. As a result, the medium goes from an exclusive high art form to more of an everyday language—think what smartphones have done to photography.

So imagine you could send your father a professionally produced song all about him for his birthday, with minimal cost and effort, in a style of his preference—a modern-day birthday card. Researchers have long considered this eventuality, and now we can do it. Happy birthday, Dad!

Mr Bown’s Blues. Generated by Oliver Bown using Udio [3.75 MB (download)] Can You Create Without Control?

Whatever these systems have achieved and may achieve in the near future, they face a glaring limitation: the lack of control.

Text prompts are often not much good as precise instructions, especially in music. So these tools are fit for blind search—a kind of wandering through the space of possibilities—but not for accurate control. (That’s not to diminish their value. Blind search can be a powerful creative force.)

Viewing these tools as a practicing music producer, things look very different. Although Udio’s about page says “anyone with a tune, some lyrics, or a funny idea can now express themselves in music,” I don’t feel I have enough control to express myself with these tools.

I can see them being useful to seed raw materials for manipulation, much like samples and field recordings. But when I’m seeking to express myself, I need control.

Using Suno, I had some fun finding the most gnarly dark techno grooves I could get out of it. The result was something I would absolutely use in a track.

But I found I could also just gladly listen. I felt no compulsion to add anything or manipulate the result to add my mark.

And many jurisdictions have declared that you won’t be awarded copyright for something just because you prompted it into existence with AI.

For a start, the output depends just as much on everything that went into the AI—including the creative work of millions of other artists. Arguably, you didn’t do the work of creation. You simply requested it.

New Musical Experiences in the No-Man’s Land Between Production and Consumption

So Udio’s declaration that anyone can express themselves in music is an interesting provocation. The people who use tools like Suno and Udio may be considered more consumers of music AI experiences than creators of music AI works, or as with many technological impacts, we may need to come up with new concepts for what they’re doing.

A shift to generative music may draw attention away from current forms of musical culture, just as the era of recorded music saw the diminishing (but not death) of orchestral music, which was once the only way to hear complex, timbrally rich and loud music. If engagement in these new types of music culture and exchange explodes, we may see reduced engagement in the traditional music consumption of artists, bands, radio and playlists.

While it is too early to tell what the impact will be, we should be attentive. The effort to defend existing creators’ intellectual property protections, a significant moral rights issue, is part of this equation.

But even if it succeeds I believe it won’t fundamentally address this potentially explosive shift in culture, and claims that such music might be inferior also have had little effect in halting cultural change historically, as with techno or even jazz, long ago. Government AI policies may need to look beyond these issues to understand how music works socially and to ensure that our musical cultures are vibrant, sustainable, enriching, and meaningful for both individuals and communities.

A Massive Study Is Revealing Why Exercise Is So Good for Our Health

Singularity HUB - 6 Květen, 2024 - 21:30

We all know that exercise is good for us.

A brisk walk of roughly an hour a day can stave off chronic diseases, including heart or blood vessel issues and Type 2 diabetes. Regular exercise delays memory loss due to aging, boosts the immune system, slashes stress, and may even increase lifespan.

For decades, scientists have tried to understand why. Throughout the body, our organs and tissues release a wide variety of molecules during—and even after—exercise to reap its benefits. But no single molecule works alone. The hard part is understanding how they collaborate in networks after exercise.

Enter the Molecular Transducers of Physical Activity Consortium (MoTrPAC) project. Established nearly a decade ago and funded by the National Institutes of Health (NIH), the project aims to create comprehensive molecular maps of how genes and proteins change after exercise in both rodents and people. Rather than focusing on single proteins or genes, the project takes a Google Earth approach—let’s see the overall picture.

It’s not simply for scientific curiosity. If we can find important molecular processes that trigger exercise benefits, we could potentially mimic those reactions using medications and help people who physically can’t work out—a sort of “exercise in a pill.”

This month, the project announced multiple results.

In one study, scientists built an atlas of bodily changes before, during, and after exercise in rats. Altogether, the team collected nearly 9,500 samples across multiple tissues to examine how exercise changes gene expression across the body. Another study detailed differences between sexes after exercise. A third team mapped exercise-related genes to those associated with diseases.

According to the project’s NIH webpage: “When the MoTrPAC study is completed, it will be the largest research study examining the link between exercise and its improvement of human health.”

Work It

Our tissues are chatterboxes. The gut “talks” to the brain through a vast maze of molecules. Muscles pump out proteins to fine-tune immune system defenses. Plasma—the liquid part of blood—can transfer the learning and memory benefits of running when injected into “couch potato” mice and delay cognitive decline.

Over the years, scientists have identified individual molecules and processes that could mediate these effects, but the health benefits are likely due to networks of molecules working together.

“MoTrPAC was launched to fill an important gap in exercise research,” said former NIH director Dr. Francis Collins in a 2020 press release. “It shifts focus from a specific organ or disease to a fundamental understanding of exercise at the molecular level—an understanding that may lead to personalized, prescribed exercise regimens based on an individual’s needs and traits.”

The project has two arms. One observes rodents before, during, and after wheel running to build comprehensive maps of molecular changes due to exercise. These maps aim to capture gene expression alongside metabolic and epigenetic changes in multiple organs.

Another arm will recruit roughly 2,600 healthy volunteers aged 10 to over 60 years old. With a large pool of participants, the team hopes to account for variation between people and even identify differences in the body’s response to exercise based on age, gender, or race. The volunteers will undergo 12 weeks of exercise, either endurance training—such as long-distance running—or weightlifting.

Altogether, the goal is to detect how exercise affects cells at a molecular level in multiple tissue types—blood, fat, and muscle.

Exercise Encyclopedia

Last week, MoTrPAC released an initial wave of findings.

In one study, the group collected blood and 18 different tissue samples from adult rats, both male and female, as they happily ran for a week to two months. The team then screened how the body changes with exercise by comparing rats that work out with “couch potato” rats as a baseline. Physical training increased the rats’ aerobic capacity—the amount of oxygen the body can use—by roughly 17 percent.

Next, the team analyzed the molecular fingerprints of exercise in whole blood, plasma, and 18 solid tissues, including heart, liver, lung, kidney, fat tissue, and the hippocampus, a brain region associated with memory. They used an impressive array of tools that, for example, captured changes in overall gene expression and the epigenetic landscape. Others mapped differences in the body’s proteins, fat, immune system, and metabolism.

“Altogether, datasets were generated from 9,466 assays across 211 combinations of tissues and molecular platforms,” wrote the team.

Using an AI-based method, they integrated the results across time into a comprehensive molecular map. The map pinpointed multiple molecular changes that could dampen liver diseases, inflammatory bowel disease, and protect against heart health and tissue injuries.

All this represents “the first whole-organism molecular map” capturing how exercise changes the body, wrote the team. (All of the data is free to explore.)

Venus and Mars

Most previous studies on exercise in rodents focused on males. What about the ladies?

After analyzing the MoTrPAC database, another study found that exercise changes the body’s molecular signaling differently depending on biological sex.

After running, female rats triggered genes in white fat—the type under the skin—related to insulin signaling and the body’s ability to form fat. Meanwhile, males showed molecular signatures of a ramped up metabolism.

With consistent exercise, male rats rapidly lost fat and weight, whereas females maintained their curves but with improved insulin signaling, which might protect them against heart diseases.

A third study integrated gene expression data collected from exercised rats with disease-relevant gene databases previously found in humans. The goal is to link workout-related genes in a particular organ or tissue with a disease or other health outcome—what the authors call “trait-tissue-gene triplets.” Overall, they found 5,523 triplets “to serve as a valuable starting point for future investigations,” they wrote.

We’re only scratching the surface of the complex puzzle that is exercise. Through extensive mapping efforts, the project aims to eventually tailor workout regimens for people with chronic diseases or identify key “druggable” components that could confer some health benefits of exercise with a pill.

“This is an unprecedented large-scale effort to begin to explore—in extreme detail—the biochemical, physiological, and clinical impact of exercise,” Dr. Russell Tracy at the University of Vermont, a MoTrPAC member, said in a press release.

This Plastic Is Embedded With Bacterial Spores That Break It Down After It’s Thrown Out

Singularity HUB - 2 Květen, 2024 - 20:49

Getting microbes to eat plastic is a frequently touted solution to our growing waste problem, but making the approach practical is tricky. A new technique that impregnates plastic with the spores of plastic-eating bacteria could make the idea a reality.

The impact of plastic waste on the environment and our health has gained increasing attention in recent years. The latest round of UN talks aiming for a global treaty to end plastic pollution just concluded in Ottawa, Canada earlier this week, though considerable disagreements remain.

Recycling will inevitably be a crucial ingredient in any plan to deal with the problem. But a 2022 report from the Organization for Economic Cooperation and Development found only 9 percent of plastic waste ever gets recycled. That’s partly due to the fact that existing recycling approaches are energy intensive and time consuming.

This has spurred a search for new approaches, and one of the most promising is the use of bacteria to break down plastics, either by rendering them harmless or using them to produce building blocks that can be repurposed into other valuable materials and chemicals. The main problem with the approach is making sure plastic waste ends up in the same place as these plastic-loving bacteria.

Now, researchers have come up with an ingenious solution: embed microbes in plastic during the manufacturing process. Not only did the approach result in 93 percent of the plastic biodegrading within five months, but it even increased the strength and stretchability of the material.

“What’s remarkable is that our material breaks down even without the presence of additional microbes,” project co-leader Jon Pokorski from the University of California San Diego said in a press release.

“Chances are, most of these plastics will likely not end up in microbially rich composting facilities. So this ability to self-degrade in a microbe-free environment makes our technology more versatile.”

The main challenge when it came to incorporating bacteria into plastics was making sure they survived the high temperatures involved in manufacturing the material. The researchers worked with a soft plastic called thermoplastic polyurethane (TPU), which is used in footwear, cushions, and memory foam. TPU is manufactured by melting pellets of the material at around 275 degrees Fahrenheit and then extruding it into the desired shape.

Given the need to survive these high temperatures, the researchers selected a plastic-eating bacteria called Bacillus subtilis, which can form spores allowing it to survive harsh conditions. Even then, they discovered more than 90 percent of the bacteria were killed in under a minute at those temperatures.

So, the team used a technique called adaptive laboratory evolution to create a more heat-tolerant strain of the bacteria. They dunked the spores in boiling water for increasing lengths of time, collecting the survivors, growing the population back up, and then repeating the process. Over time, this selected for mutations that conferred greater heat tolerance, until the researchers were left with a strain that was able to withstand the manufacturing process.

When they incorporated the spores into the plastic, they were surprised to find the bacteria actually improved the mechanical properties of the material. In essence, the spores acted like steel rebar in concrete, making it harder to break and increasing its stretchability.

To test whether the impregnated spores could help the plastic biodegrade, the researchers took small strips of the plastic and put them in sterilized compost. After five months, they found the strips had lost 93 percent of their mass compared to 44 percent for TPU without spores, which suggests the spores were reactivated by nutrients in the compost and helped degrade the plastic substantially faster.

It’s unclear if the approach would work with other plastics, though the researchers say they plan to find out. There is also a danger the spores could reactivate before the plastic is disposed of, which could shorten the life of any products made with it. Perhaps most crucially, plastics researcher Steve Fletcher from the University of Portsmouth in the UK told the BBC that this kind of technology could distract from efforts to limit plastic waste.

“Care must be taken with potential solutions of this sort, which could give the impression that we should worry less about plastic pollution because any plastic leaking into the environment will quickly, and ideally safely, degrade,” he said. “For the vast majority of plastics, this is not the case.”

Given the scale of the plastic pollution problem today though, any attempt to mitigate the harm should be welcomed. While it’s early days, the prospect of making plastic that can biodegrade itself could go a long way towards tackling the problem.

Make Music A Full Body Experience With A “Vibro-Tactile” Suit

Futurism - Enhanced Humans - 27 Září, 2018 - 17:09

Tired: Listening to music.
Wired: Feeling the music.

A mind-bending new suit straps onto your torso, ankles and wrists, then uses actuators to translate audio into vivid vibration. The result: a new way for everyone to experience music, according to its creators. That’s especially exciting for people who have trouble hearing.


The Music: Not Impossible suit was created by design firm Not Impossible Labs and electronics manufacturing company Avnet. The suit can create sensations to go with pre-recorded music, or a “Vibrotactile DJ” can adjust the sensations in real time during a live music event.”

Billboard writer Andy Hermann tried the suit out, and it sounds like a trip.

“Sure enough, a pulse timed to a kickdrum throbs into my ankles and up through my legs,” he wrote. “Gradually, [the DJ] brings in other elements: the tap of a woodblock in my wrists, a bass line massaging my lower back, a harp tickling a melody across my chest.”


To show the suit off, Not Impossible and Avnet organized a performance this past weekend by the band Greta Van Fleet at the Life is Beautiful Festival in Las Vegas. The company allowed attendees to don the suits. Mandy Harvey, a deaf musician who stole the show on America’s Got Talent last year, talked about what the performance meant to her in a video Avnet posted to Facebook.

“It was an unbelievable experience to have an entire audience group who are all experiencing the same thing at the same time,” she said. “For being a deaf person, showing up at a concert, that never happens. You’re always excluded.”

“Synthetic Skin” Could Give Prosthesis Users a Superhuman Sense of Touch

Futurism - Enhanced Humans - 20 Září, 2018 - 21:37

Today’s prosthetics can give people with missing limbs the ability to do almost anything — run marathons, climb mountains, you name it. But when it comes to letting those people feel what they could with a natural limb, the devices, however mechanically sophisticated, invariably fall short.

Now researchers have created a “synthetic skin” with a sense of touch that not only matches the sensitivity of natural skin, but in some cases even exceeds it. Now the only challenge is getting that information back into the wearer’s nervous system.


When something presses against your skin, your nerves receive and transmit that pressure to the brain in the form of electrical signals.

To mimic that biological process, the researchers suspended a flexible polymer, dusted with magnetic particles, over a magnetic sensor. The effect is like a drum: Applying even the tiniest amount of pressure to the membrane causes the magnetic particles to move closer to the sensors, and they transmit this movement electronically.

The research, which could open the door to super-sensitive prosthetics, was published Wednesday in the journal Science Robotics.


Tests shows that the skin can sense extremely subtle pressure, such as a blowing breeze, dripping water, or crawling ants. In some cases, the synthetic skin responded to pressures so gentle that natural human skin wouldn’t be able to detect them.

While the sensing ability of this synthetic skin is remarkable, the team’s research doesn’t address how to transmit the signals to the human brain. Other scientists are working on that, though, so eventually this synthetic skin could give prosthetic wearers the ability to feel forces even their biological-limbed friends can’t detect.

People Are Zapping Their Brains to Boost Creativity. Experts Have Concerns.

Futurism - Enhanced Humans - 19 Září, 2018 - 21:56

There’s a gadget that some say can help alleviate depression and enhance creativity. All you have to do is place a pair of electrodes on your scalp and the device will deliver electrical current to your brain. It’s readily available on Amazon or you can even make your own.

But in a new paper published this week in the Creativity Research Journal, psychologists at Georgetown University warned that the practice is spreading before we have a good understanding of its health effects, especially since consumers are already buying and building unregulated devices to shock them. They also cautioned that the technique, which scientists call transcranial electrical stimulation (tES), could have adverse effects on the brains of young people.

“There are multiple potential concerns with DIY-ers self-administering electric current to their brains, but this use of tES may be inevitable,” said co-author Adam Green in a press release. “And, certainly, anytime there is risk of harm with a technology, the scariest risks are those associated with kids and the developing brain”


Yes, there’s evidence that tES can help patients with depression, anxiety, Parkinson’s disease, and other serious conditions, the Georgetown researchers acknowledge.

But that’s only when it’s administered by a trained health care provider. When administering tES at home, people might ignore safety directions, they wrote, or their home-brewed devices could deliver unsafe amounts of current. And because it’s not yet clear what effects of tES might be on the still-developing brains of young people, the psychologists advise teachers and parents to resist the temptation to use the devices to encourage creativity among children.

The takeaway: tES is likely here to stay, and it may provide real benefits. But for everyone’s sake, consumer-oriented tES devices should be regulated to protect users.

Military Pilots Can Control Three Jets at Once via a Neural Implant

Futurism - Enhanced Humans - 19 Září, 2018 - 16:25

The military is making it easier than ever for soldiers to distance themselves from the consequences of war. When drone warfare emerged, pilots could, for the first time, sit in an office in the U.S. and drop bombs in the Middle East.

Now, one pilot can do it all, just using their mind — no hands required.

Earlier this month, DARPA, the military’s research division, unveiled a project that it had been working on since 2015: technology that grants one person the ability to pilot multiple planes and drones with their mind.

“As of today, signals from the brain can be used to command and control … not just one aircraft but three simultaneous types of aircraft,” Justin Sanchez, director of DARPA’s Biological Technologies Office, said, according to Defense One.


Sanchez may have unveiled this research effort at a “Trajectory of Neurotechnology” session at DARPA’s 60th anniversary event, but his team has been making steady progress for years. Back in 2016, a volunteer equipped with a brain-computer interface (BCI) was able to pilot an aircraft in a flight simulator while keeping two other planes in formation — all using just his thoughts, a spokesperson from DARPA’s Biological Technologies Office told Futurism.

In 2017, Copeland was able to steer a plane through another simulation, this time receiving haptic feedback — if the plane needed to be steered in a certain direction, Copeland’s neural implant would create a tingling sensation in his hands.


There’s a catch. The DARPA spokesperson told Futurism that because this BCI makes use of electrodes implanted in and on the brain’s sensory and motor cortices, experimentation has been limited to volunteers with varying degrees of paralysis. That is: the people steering these simulated planes already had brain electrodes, or at least already had reason to undergo surgery.

To try and figure out how to make this technology more accessible and not require surgical placement of a metal probe into people’s brains, DARPA recently launched the NExt-Generation Nonsurgical Neurotechnology (N3) program. The plan is to make a device with similar capabilities, but it’ll look more like an EEG cap that the pilot can take off once a mission is done.

“The envisioned N3 system would be a tool that the user could wield for the duration of a task or mission, then put aside,” said Al Emondi, head of N3, according to the spokesperson. “I don’t like comparisons to a joystick or keyboard because they don’t reflect the full potential of N3 technology, but they’re useful for conveying the basic notion of an interface with computers.”

Lab-Grown Bladders Can Save People From a Lifetime of Dialysis

Futurism - Enhanced Humans - 12 Září, 2018 - 22:54

Today, about 10 people on Earth have bladders they weren’t born with. No, they didn’t receive bladder transplants — doctors grew these folks new bladders using the recipients’ own cells.

On Tuesday, the BBC published a report on the still-nascent procedure of transplanting lab-grown bladders. In it, the publication talks to Luke Massella, who underwent the procedure more than a decade ago. Massella was born with spina bifida, which carries with it a risk of damage to the bladder and urinary tract. Now, he lives a normal life, he told the BBC.

“I was kind of facing the possibility I might have to do dialysis [blood purification via machine] for the rest of my life,” he said. “I wouldn’t be able to play sports, and have the normal kid life with my brother.”

All that changed after Anthony Atala, a surgeon at Boston Children’s Hospital, decided he was going to grow a new bladder for Massella.


To do that, Atala first removed a small piece of Massella’s own bladder. He then removed cells from this portion of bladder and multiplied them in a petri dish. Once he had enough cells, he coated a scaffold with the cells and placed the whole thing in a temperature controlled, high oxygen environment. After a few weeks, the lab-created bladder was ready for transplantation into Massella.

“So it was pretty much like getting a bladder transplant, but from my own cells, so you don’t have to deal with rejection,” said Massella.

The number of people with lab-grown bladders might still be low enough to count on your fingers, but researchers are making huge advances in growing everything from organs to skin in the lab. Eventually, we might reach a point when we can replace any body part we need to with a perfect biological match that we built ourselves.
