New Spinal Cord Treatment Lets Paralyzed Man Stand for the First Time in Years


Giant Steps For Humankind

Researchers at the Mayo Clinic successfully used intense physical therapy and electrical stimulation on the spinal cord to help a patient stand, intentionally move his paralyzed legs, and make step-like motions. These were the first movements the patient had experienced in his legs in three years.

26-year-old Jered Chinnock injured his spinal cord at the sixth thoracic vertebrae three years ago. He could not move or feel anything lower than the middle of his back, and was diagnosed with a motor complete spinal cord injury.

At the outset of the study, Chinnock underwent 22 weeks of physical therapy with three training sessions per week. His training goal was to prepare his muscles so they would be strong enough to attempt the physical tasks while his spinal cord was being stimulated.

Next, the team implanted an electrode below the injured area in the epidural space, close to the spinal cord, and a computer-controlled device just under the patient’s abdominal skin. The FDA gave permission to the Mayo Clinic for this off-label use of the device, which controls the transmission of an electrical current to the spinal cord, which in turn allowed the patient to create movement in his muscles.

After a recovery period, Chinnock resumed his physical therapy sessions with the stimulation settings for the device adjusted to enable his muscle movements. Within the first two weeks, he was able to intentionally move his legs and make step-like motions while lying supported, on his side. He was also able to stand independently using support bars. The intentional movement indicates that his brain is once again able to signal his spinal cord successfully.

 “We’re really excited, because our results went beyond our expectations,” says neurosurgeon Kendall Lee, the study’s principal investigator. “These are initial findings, but the patient is continuing to make progress.”

A Long Road Ahead

For Jered Chinnock, the results are something to get used to. “It definitely feels like science fiction,” he said. “The first day they turned it on, it was almost mind-blowing because it was, like, right away I was able to move my toes, and it was something I haven’t seen in a while, you know.”

As amazing as the experiment is, it’s still early work. Although the data seems to indicate that epidural stimulation therapy may work for people with discomplete spinal cord injuries, current classification of such injuries is vague. It includes only general information about the status of the injury and omits characterizations of specific descending or ascending spinal pathways. This reflects the limitations on our current diagnostic approaches.

More research is needed to determine how researchers and physicians can identify which pathways are still transmitting residual descending and ascending—albeit subfunctional—signals in patients with these types of injuries. In addition, the extent to which neural substrates underlie the phenomenon of discomplete SCI and contribute to EES-enabled functional recovery has yet to be determined. However, these results have clarified those long-term research goals, and prove that this technique is very promising.

We Just Created an Artificial Synapse That Can Learn Autonomously


IN BRIEF

A team of researchers has developed artificial synapses that are capable of learning autonomously and can improve how fast artificial neural networks learn.

MIMICKING THE BRAIN

Developments and advances in artificial intelligence (AI) have been due in large part to technologies that mimic how the human brain works. In the world of information technology, such AI systems are called neural networks. These contain algorithms that can be trained, among other things, to imitate how the brain recognizes speech and images. However, running an Artificial Neural Network consumes a lot of time and energy.

Now, researchers from the National Center for Scientific Research (CNRS) in Thales, the University of Bordeaux in Paris-Sud, and Evry have developed an artificial synapse called a memristor directly on a chip. It paves the way for intelligent systems that required less time and energy to learn, and it can learn autonomously.

In the human brain, synapses work as connections between neurons. The connections are reinforced and learning is improved the more these synapses are are stimulated. The memristor works in a similar fashion. It’s made up of a thin ferroelectric layer (which can be spontaneously polarized) that is enclosed between two electrodes. Using voltage pulses, their resistance can be adjusted, like biological neurons. The synaptic connection will be strong when resistance is low, and vice-versa. The memristor’s capacity for learning is based on this adjustable resistance.

 

BETTER AI

AI systems have developed considerably in the past couple of years. Neural networks built with learning algorithms are now capable of performing tasks which synthetic systems previously could not do. For instance, intelligent systems can now compose music, play games and beat human players, or do your taxes. Some can even identify suicidal behavior, or differentiate between what is lawful and what isn’t.

Understanding Machine Learning [INFOGRAPHIC]

This is all thanks to AI’s capacity to learn, the only limitation of which is the amount of time and effort it takes to consume the data that serve as its springboard. With the memristor, this learning process can be greatly improved. Work continues on the memristor, particularly on exploring ways to optimize its function. For starters, the researchers have successfully built a physical model to help predict how it functions. Their work is published in the journal Nature Communications.

Soon, we may have AI systems that can learn as well as out brains can — or even better.

True Freedom Comes With Basic Income


IN BRIEF
  • Numerous studies show that sex trafficking is largely the means for those without means to obtain the requirements of life from those with means.
  • A universal basic income would give those involved in trafficking the ability to choose a different life other than the one they are currently compelled to live.

I attended a national economic conference in New York in 2015, and in one of the presentations, the speaker presented the following claim: human trafficking is not so much a criminal issue as it is an economic vulnerability issue, and therefore the best tool we have to strike at the very root of the problem is a universal basic income.

This idea of a basic income guarantee — an amount of money given to all without any conditions aside from mostly citizenship (and perhaps age) — is an idea that has been around for centuries and yet only recently is really starting to noticeably catch fire in the minds of the public at large. It is being referred to in such terms as “an idea whose time has come,” “an end to poverty,” and “venture capital for the people.” Fast Company has dubbed it a “bipartisan world changing idea.” The New York Times has even asked, “Why Not Utopia?” in light of growing warnings of structural unemployment due to accelerating technological advancements like self-driving cars and artificial intelligenceOutlet after outlet is beginning to seriously discuss this policy once considered outside the Overton Window of political possibility.

So what’s all the fuss? Is basic income really that powerful of an idea?

The short answer is yes, it really is that powerful of an idea. It’s such a powerful idea for the same reason it has even been suggested in a conference full of economists as the best tool for reducing human trafficking. That reason is actually quite simple, but very far reaching. As long as we face starvation and homelessness, we are at the whims of others.

This is the face of economic vulnerability and it lies at the very heart of a great deal of systemic issues. Think for a moment about what difference it would make in your own life to be guaranteed $1,000 would always appear in your bank account at the beginning of every month for the rest of your life, no matter what you did. How would that money change your life? How would it affect the decisions you face every day? How would it affect your relationships with others from your boss to your spouse? How would it affect your choices?

Consider that word: “choice.” What is choice, really? When it comes to any real choice in life, what it all boils down to is the ability to simply say “No.” Without that ability, nothing is truly voluntary. All work isn’t voluntary. All relationships aren’t voluntary. All market exchanges aren’t voluntary. The choices we make that we think are choices aren’t truly voluntary whenever the option to say “No” is off the table. Therein lies the full potential of the idea of a universal basic income, and it lays bare the lack of power many of us are under the illusion of having. Having a basic income creates the ability to look someone in the eye who holds more power than you and firmly say, “No. Not today. Not until things change. These are my terms. Take them or leave them.”

Basic Income

That power only arises with unconditional access to the means of survival, which is what a basic income essentially is. As long as we are refused access to the resources required to live, we will make choices we would not otherwise make. We will do things to make money we would not otherwise do. We will say things where we would otherwise stay quiet and keep silent where we would otherwise be heard.

Italy recently acknowledged this in their call for a citizen’s income to reduce mafia power, to “remove oxygen from those who exploit the need to work and turn it into economic blackmail.” Living in a climate of perpetual shakedowns has made clear to Italians the need for the enhanced ability to decline. Without that ability, people have little choice at all but to accept exploitation as part of everyday life.

We are all making choices right now that aren’t really choices at all, and if we look around, we can begin to see them for what they truly are — compulsions. We are compelled to sell ourselves to others. We are compelled to put our trust in others. And we are compelled to hope in ways that are destructive.

THE COMPULSION TO SELL YOURSELF

Sex work is known as the world’s oldest profession for a reason, and that reason is because as soon as money was invented, there was someone wanting to obtain sex in exchange for it, and also someone who needed money to exchange for food and housing. For thousands of years, to this day, that has remained true.

In a 1998 study of 475 people engaged in prostitution across five countries (including the US), 92 percent claimed they wanted to leave prostitution but couldn’t due to a lack of money or food. In other words, potentially only eight out of every 100 prostitutes are voluntarily engaged in sex work.

“From the perspective of those we interviewed in five countries, prostitution might at best be called a means of survival: if one wants a place to sleep, food to eat, and a way to briefly get off the street, one allows oneself to be sexually assaulted.”

That prostitution appears to primarily exist as a means of escaping starvation and homelessness is additionally supported by the finding that in the US, 84 percent of 130 prostitutes living in the San Francisco Bay Area when interviewed reported being homeless at the time, or were once homeless. This is not only reported in America. In the same five-nation study cited above, on average, 72 percent reported current or past homelessness.

There are those who will look at such numbers and claim they are false — that they are created to serve an agenda that wishes to abolish all sex work. So let’s assume for a moment they are inaccurate and that the number is closer to 50 percent or even 25 percent instead of 92 percent. Just how low does that number need to get before it is entirely acceptable for that percentage of people to feel forced into sex work for lack of options?

Sex work is not a fully free choice. It is largely the means for those without means to obtain the requirements of life from those with means. And that’s exactly how it will continue to exist, until everyone is freely given access to the requirements for life.

However, sex work is also not the only way of being compelled to sell ourselves. This method of compulsion is also to be found in any job that involves accepting a rate of pay below which anyone would ever actually accept if not for the overwhelming fear of going without anything at all. The all too common belief that something is better than nothing, in a world that guarantees nothing, lies underneath every wage and salary negotiation.

For example, the movement for a higher minimum wage is gaining prominence in the national discussion as the “Fight for 15” wages on. But how many fast food workers would’ve ever accepted a lower wage to begin with, if they’d already been receiving a check for citizenship at the end of every month, along with everyone else, sufficient to cover their most basic needs? If every worker had more bargaining power as individuals, would we all be so willing to sell ourselves to so many for so little?

“The all too common belief that something is better than nothing, in a world that guarantees nothing, lies underneath every wage and salary negotiation.”

Exploitation is also not only about wages and salaries. It’s about time. How many people are working in jobs that aren’t offering them enough hours or anything resembling a sane work schedule that doesn’t vary by the week? These are manifested in the decline of full-time jobs and the rise of part-time jobs where 6.9 million workers in the US report working part-time not because they choose to but because they have to. It’s in the rise of zero-hour contracts and irregular work schedules where 17 percent of workers now report having irregular schedules.

All of this is essentially about working conditions. How many workers globally now work in jobs with conditions they would never otherwise agree to, were they armed with basic incomes they’d keep either way? How many workers would refuse conditions they personally deem insufficient if they were guaranteed a separate income stream independent of employment? When we consider a question like this, let us too consider being in the shoes of one of the employees who upon walking up to the doors of the Rana Plaza building in Bangladesh on April 24th 2013, wondered if it would collapse that day and walked inside any way. Is someone more likely or less likely to walk into a building they worry might collapse in order to avoid losing their job, if not walking in no longer represents the risk their families may go hungry?

These are our compulsions and they do not even stop here. Without a basic income, we also have a compulsion to believe others, taking them for their word when we shouldn’t.

THE COMPULSION TO TRUST

As the saying goes, “There’s a sucker born every minute.” Unfortunately, such victims tend to be among those most economically vulnerable. Fraud has been on the rise for decades thanks to: the technology that makes it even easier to accomplish, the incomes that have been falling for decades when adjusted for inflation, and the dramatic shift in federal manpower post-9/11 from fraud to terrorism. As a result, we’re now spending $50 billion a year on scams, and even worse this rising level of fraud prominently includes “last dollar” fraud, a moniker for the type of fraud aimed at taking the very last dollar from the hands of those most in need of every dollar they can get.

For every ad on the internet that claims you’ve won an iPad, for every request for personal information to claim the airline tickets you never bought or package you never ordered, for every coupon claiming to be worth $50, for every amazing deal where something can be purchased at 50 percent off or more, for every job offering a high wage for seemingly little effort and especially in the comfort of one’s home, there’s a scam artist looking to exploit trust. And there’s also someone willing to make that leap of faith because if it just so happens to be true, there’s a light finally shining at the end of a very dark tunnel.

Having no other real choice but to trust doesn’t stop at individual scammers. It extends also to private corporations and government itself. Consider the trust we put in companies like Google to stay true to their word of “Do no evil”, so that we may continue happily using their free products as fewer and fewer people can afford to pay for all that isn’t free. Consider how we learned that trust had been betrayed in the NSA revelations brought forth by Edward Snowden. Would more people boycott companies that violate their privacy if they could afford the alternatives that cost more than zero dollars?

“Need makes us vulnerable to those who wish to take advantage of it.”

Think of the trust we place in government to represent our common interest, despite the growing awareness it doesn’t. What recourse do citizens have but to trust and hope for the best when they are so busy working to just barely scrape by? When only 30 percent of those earning less than $15,000 are likely to vote versus the 80 percent likely to vote earning more than six figures, just how much time do the poorest really have to actually exercise their rights of citizenship?

This is all a compulsion to trust. The person with limited options is the one far more likely to ignore the voice in all of our heads that tells us something is too good to be true. Need makes us vulnerable to those who wish to take advantage of it. Need leaves us open for betrayal. The best way to combat this is to strike at the very foundation of it, and reduce need itself.

Finally, and possibly most destructively of all, there exists the compulsion for something so precious, it perpetually remains our Achilles Heel — our desire to focus on something so precious and so powerful, we become blinded to everything else.

THE COMPULSION TO HOPE

Hope is everything. Hope drives us in ways so incredible we can actually accomplish the impossible. It also drives us in ways that destroy. It is hope that lies at the heart of our most extreme risk-taking, where we can be told the odds of victory are 1 percent, and we will consider those odds entirely acceptable.

The odds of winning a Mega Millions lottery jackpot is about 1 in 259 million. Because states use their collective $27.9 billion on lottery ticket salesin place of taxes, this kind of revenue functions as an implicit additional tax at a rate of 26 percent to 56 percent varying by state. In other words, if all you have is $10 in the state of Louisiana and you spend it on lottery tickets, you effectively just gave $5.60 to the Department of Revenue.

Meanwhile, even though all income quintiles spend about the same amount each year on lottery tickets, every ticket purchased by those with little money represents a much larger share of their total available income. A recent estimate places this percentage of income spent on lottery tickets by those earning $13,000 or less at around 2 percent to 3 percent, while those earning more than $70,000 (in 1991 dollars) are spending less than 0.18 percent.

What makes someone with $10 to their name spend $1 on a lottery ticket at the same rate as someone with a six figure savings account? The answer is those with the means can afford to gamble. Those without can’t. But those without are still spending their money in hopes it can change their lives, even though all it does is make their lives worse. Why?

They do it for the same reason they take out loans at interest rates above 1000 percent.

They do it for the same reason hundreds of migrants died on a capsized boat.

They do it for the same reason 20.9 million people worldwide are estimated by the ILO to be “trapped in jobs into which they were coerced or deceived and which they cannot leave.”

They do it because for them, money is scarce, the potential for money exists elsewhere, and because jobs — of any kind whatsoever — represent the only means of life.

If anyone claims we don’t know how to solve all of this, they’re either lying or ignorant of what’s already been proven to work.

“As long as people remain walled off from access to the resources they need to live, through the withholding of cash on the condition of working for others, the powerless will continue to be exploited.”

WHAT WE KNOW

In a 2014 global review of empirical evidence on the impact on child labor of cash transfers with and without conditions, the World Bank found “broad evidence that conditional and unconditional cash transfers both lower children’s participation in child labor and hours worked, and cushion the effect of economic shocks that may lead households to use child labor as a coping strategy.”

Such findings are important to know because child labor is greatly connected to human trafficking. Parents in need of extra family income will put their children to work, and this can open them up to (or even directly result in) forced labor or sexual exploitation, of which 6 million kids are currently trapped.

There also exists data from actual basic income experiments, where money is given to entire areas instead of targeted only at the poor. In one such experiment in India, findings included strong “capability” effects where the socio-economic statuses of women, the elderly, and the disabled all improved. Additionally there were strong “equity” effects where the largest improvements were seen among lower castes and those considered more vulnerable such as the disabled and frail. There were also “emancipatory” effects where those in debt paid their way out of bondage by paying down high interest loans. Additionally, people were enabled to avoid taking on new debts and even build savings. The money helped everyone, but had greater effects on the traditionally marginalized.

When people in Namibia were given basic incomes in their pilot experiment, self-employment there increased by 301%. It was the main source of income growth. Income from self-employment actually reached the level of income from wages. People with little to no incomes, when given money, put themselves to work. Crime rates were reduced by over 40%. Illegal hunting — something that can be considered a crime born of utter desperation and the need to eat — was reduced 95%. This is what reduced need looks like.

It is well known and well-studied that just giving people money reduces their need to make hard choices. When your body is all you have, it’s all you can sell. When you have at least some money unconditionally, it functions as starting capital to open up a whole range of new choices. This is why basic income experiments show increased entrepreneurship. GiveDirectly — a charity built entirely around unconditional cash transfers and also embarking on a 12-year universal basic income experiment in East Africa — refers to this phenomenon in stating, “There’s no charity for power saws.”

Naturally, someone who wants to start a business chopping trees needs a saw, but if they have no money they can’t obtain one. Meanwhile it’s difficult to get a loan for one or ask a charity for one. It’s cash that people need so as to afford the work they wish to pursue, and in these pursuits, they are very creative. Without the necessary cash, they must pursue the work they might not wish to pursue, and that might leave them worse off.

As long as people remain walled off from access to the resources they need to live, through the withholding of cash on the condition of working for others, the powerless will continue to be exploited. Slavery will continue. Human trafficking will continue. Violence and crime will continue.

COMPULSION ENDS WITH BASIC INCOME

This is why Sex Worker Open University has actively called for a universal basic income. It’s also why there are now calls for the anti-slavery movement to do the same.

This is why a Rape and Women’s shelter in Vancouver actively supports universal basic income. It’s also why the Women’s Campaign of the UK’s National Union of Students has resolved to “widely publicize the societal need for a Universal Basic Income” as “an extremely important feminist issue.”

This is all why Ashley Engel stated in her presentation about fighting human trafficking with basic income, “only when a person is not monetarily vulnerable enough to be trafficked can trafficking be reduced. A UBI offers an effective mechanism to prevent such a horrific trade and is key to ensuring freedom for all.”

Freedom for all… this is an idea so far only spoken about in rhetoric and hypotheticals. There will never be true freedom from exploitation and all forms of slavery until freedom is actually granted unconditionally to all, with unconditional basic income.

Until that day comes, the decisions we make will remain compulsory instead of free.

Parkinson’s May Actually Originate From Microbes in the Gut


IN BRIEF
  • Instead of being isolated to the brain, new evidence in mice suggests that Parkinson’s disease might actually start in the gut.
  • The study could help in finding the cure for Parkinson’s, a neurodegenerative disease affecting an estimated 10 million people worldwide.

THE ROOT CAUSE?

In the many studies that seek to decode the mystery that is Parkinson’s disease, scientists have confined their search to the brain. However, new research suggests that the neurodegenerative disease may actually originate in the gut. The study is detailed in the journal Cell.

Researchers have noticed that people with Parkinson’s often report constipation, as well as other digestive problems, up to ten years before tremors (the usual symptoms of Parkinson’s) cropped up. The study attributed a microbe in the gut to protein mutations in the brain known to cause Parkinson’s.

parkinson's disease microbial disease digestive problems neurodegenerative diseasesMice bred to develop Parkinson’s were put in cages that were either sterile or non-sterile. The mice in the germ-free cages manifested less motor degeneration, and their brains had reduced tangling of the protein α-synuclein. They had “almost normal performance” in motor tasks. The researchers injected gut bacteria from human Parkinson’s patients into these mice, and they deteriorated quickly. This effect did not occur with bacteria taken from healthy humans.

The mice in the normal, non-sterile cages developed the expected symptoms of Parkinson’s. When treated with antibiotics, their symptoms were reduced, suggesting effectiveness in a microbial approach to the disease.

Gut bacteria taken from healthy people didn’t have the same effect.

HOPE FOR A CURE

“We have discovered for the first time a biological link between the gut microbiome and Parkinson’s disease,” said Sarkis Mazmanian, lead researcher. Essentially, the scientists think the gut bacteria might be releasing chemicals that over-activate parts of the brain, leading to damage.

What’s next for the researchers is to identify specifically which among the cocktail of gut microbiomes is causing the disease. If these certain strains could be identified, scientists could find a way to screen for the disease before symptoms appear and the brain becomes damaged.

“Much like any other drug discovery process, translating this innovative work from mice to humans will take many years,” said Mazmanian. “But this is an important first step.”

Caltech’s 2500 Orbiting Solar Panels Could Provide Earth With Limitless Energy


IN BRIEF

The Space Solar Power Initiative (SSPI), a collaboration between Caltech and Northrup Grumman, has developed a system of lightweight solar power tiles which can convert solar energy to radio waves and can be placed in orbit to beam power to an energy-thirsty Earth.

SOAKING IN THE SUN’S RAYS

One of the greatest challenges facing the 21st Century is the issue of power—how to generate enough of it, how to manufacture it cheaply and with the least amount of harmful side-effects, and how to get it to users.

The solutions will have to be very creative—rather like what the Space Solar Power Initiative(SSPI), a partnership between Caltech and Northrup Grumman, has devised.

Prototype of the “multifunctional tile.” 

“What we’re proposing, somewhat audaciously, is to develop the technology that would enable one to build the largest-ever-built space structures,” says Harry Atwater, a Caltech professor and member of SSPI.

The idea, for beaming solar energy to Earth from space, is ingenious, simple, and may just work—given the needed investment and financial backing. SSPI has engineered a modular approach which ensures low-cost and redundancy. The basic unit is a “multifunctional tile,” a lightweight photovoltaic segment that measures 10 x 10 cm (4 x 4 in), is only 3 cm (1 in) thick, weighs about 0.8 gram (0.03 oz.), and can flatten when assembled for launch.

400 of these basic tiles are assembled into panels, with 900 panels per satellite. Each of these “carpet” satellites can be folded into a small space for launch, and unfurl once in orbit to its full size, about two-thirds the size of a football field.

The concept involves 2500 of these satellites flying in a close formation, forming a solar power surface of 9 square kilometers (3.5 square miles). Each tile is capable of converting solar power into transmissible radio energy, which can be beamed to (and received on) Earth.

POWER FOR ALL

SSPI’s design for modular, space-based solar power. 

The beauty of this system is that there is no need for a costly energy infrastructure on the Earth. This means remote and impoverished regions, lacking a groundwork for energy transmission, are easily furnished with this space-based solar power. Simple antennas and receiving stations are all that’s needed.

Meanwhile, the lightweight tiles—which are cheaply manufactured—mean for a more robust space system. The usual wear and tear of long-term spacecraft, such as solar flare or micrometeorite damage, might knock out a tile or two, but wouldn’t be catastrophic to the spacecraft as a whole.

It’s an intriguing concept, and one well worth the investment. With enough interest, and a mobilization of the electronics industry to build the tiles, and the private space industry to transport them to space, it may just be the future of energy.

Kazuo Ishiguro: Soon, We Will Be Able to Create Humans Who Are Superior to Other Humans


IN BRIEF
  • Author Kazuo Ishiguro believes we are unwittingly walking into a dystopian future because the world has yet to give science and technology more than just peripheral interest.
  • He believes that we have yet to engage in meaningful conversations about where scientific advancements will take us, and the kind of impact they will have on our lives.

DYSTOPIAN FUTURE

According to Kazuo Ishiguro, there are three areas of science that are set to transform how we live and interact with others over the next few decades: gene editing, robotics, and artificial intelligence (AI).

Ishiguro, granted, is best known as one of the most celebrated fiction writers today. He is behind the novel Never Let Me Go, the story of a dystopian future where humans are cloned to be organ donors. But the possibility of a future so fundamentally changed by scientific advancements could be more than the fruit of the author’s creativity and imagination.

Ishiguro

He cites CRISPR as a primary example. The discovery of this gene editing tool gives scientists the option to modify pieces of the genome, paving the way for unprecedented applications in medicine. Right now, we can replace faulty genes with working ones, which is a great accomplishment unto itself. But moving forward, as we learn more about this new technology, the option to enhance functional genes to create intellectually and physically superior humans becomes a real possibility.

Think of it as like a real world Gattaca, where society is divided into two classes. Half will be populated with humans with genetically engineered genes that makes them healthier, smarter, stronger—designer babies, essentially. And the other half, with humans whose genetic sequence has been left to chance, untouched, leaving them biologically inferior.

A NEW FOCUS ON SCIENCE

Ishiguro believes we are unwittingly walking into this dystopian future because the world has yet to give science and technology more than just peripheral interest. Sure, we celebrate the headlines and acknowledge the accomplishments, but we have yet to engage in meaningful conversations about where these advancements will take us, and the kind of impact they will have on our lives.

Developments in AI and robotics for instance, mean a major part of intellectual capital will shift to what he refers to as “the Silicon Valley masters of the universe”—it will no longer be under universities or government funded labs. The lack of regulation regarding these rapid developments is also cause for concern. And of course, there is the ongoing debate about the ethics behind advancements in genetic sciences, like CRISPR.

The relevance of Ishiguro’s musings about the future comes in time for the opening of a new permanent mathematics gallery at the Science Museum in London. Included in the exhibit is the author’s father, oceanographer Shizuo Ishiguro, who created a machine that can predict coastal storm surges.

The author however, hopes that exhibits such as this will prompt more discussion about the trajectory of science and spur deeper interest. These breakthroughs have real implications that deserve to be discussed.

Neil deGrasse Tyson Seems Skeptical of Elon Musk’s Mars Plans


IN BRIEF

Famed astrophysicist Neil deGrasse Tyson candidly shared his thoughts on SpaceX during a recent Reddit AMA. While he seems wary of Elon Musk’s plans to send people to Mars, he spoke very positively about SpaceX’s demonstration of a reusable rocket.

Renowned astrophysicist Neil deGrasse Tyson is a little wary of Elon Musk’s ability to send humans to Mars, but he does like what he’s seeing from SpaceX overall.

Invaders From Earth!: How Elon Musk Plans to Conquer Mars

During a recent Reddit Ask Me Anything (AMA) session, Redditor patopc1999 asked, “Hi Neil! Just wanted to know your thoughts on SpaceX’s Falcon 9 relaunch and landing, and what do you think it means for the future of space travel?”

Tyson replied that “any demonstration of rocket reusability is a good thing,” and he even asserted that “reusability is arguably the most fundamental feature of affordable expensive things.”

The Redditor also wanted to know if Tyson would ever consider joining a future one-way trip to Mars, which prompted a less optimistic response: “I really like Earth. So any space trip I take, I’m double checking that there’s sufficient funds for me to return.” He candidly added, “Also, I’m not taking that trip until Elon Musk send[s] his mother and brings her back alive. Then I’m good for it.”

Elon Musk’s SpaceX recently made history by successfully launching and landing a used Falcon 9 rocket booster for the first time. The CEO has announced his intent to bring humans back to the Moon, as well, and SpaceX is looking to add hundreds of new employees to its ranks to help Musk make all these projects happen.

Given Musk’s track record for actually coming through on his plans, it could be simply a matter of time before Tyson boards a SpaceX rocket, with or without Musk’s mother riding one first.

New AI Can Write and Rewrite Its Own Code to Increase Its Intelligence


IN BRIEF
  • A company has developed a type of technology that allows a machine to effectively learn from fewer examples and refine its knowledge as further examples are provided.
  • This technology could be applied to everything from teaching a smartphone to recognize a user’s preferences to helping autonomous driving systems quickly identify obstacles.

LEARNING FROM LESS DATA

The old adage that practice makes perfect applies to machines as well, as many of today’s artificially intelligent devices rely on repetition to learn. Deep-learning algorithms are designed to allow AI devices to glean knowledge from datasets and then apply what they’ve learned to concrete situations. For example, an AI system is fed data about how the sky is usually blue, which allows it to later recognize the sky in a series of images.

Complex work can be accomplished using this method, but it certainly leaves something to be desired. For instance, could the same results be obtained by exposing deep-learning AI to fewer examples? Boston-based startup Gamalon developed a new technology to try to answer just that, and this week, it released two products that utilize its new approach.

Gamalon calls the technique it employed Bayesian program synthesis. It is based on a mathematical framework named after 18th century mathematician Thomas Bayes. The Bayesian probability is used to refine predictions about the world using experience. This form of probabilistic programming — a code that uses probabilities instead of specific variables — requires fewer examples to make a determination, such as, for example, that the sky is blue with patches of white clouds. The program also refines its knowledge as further examples are provided, and its code can be rewritten to tweak the probabilities.

PROBABILISTIC PROGRAMMING

While this new approach to programming still has difficult challenges to overcome, it has significant potential to automate the development of machine-learning algorithms. “Probabilistic programming will make machine learning much easier for researchers and practitioners,” explained Brendan Lake, an NYU research fellow who worked on a probabilistic programming technique in 2015. “It has the potential to take care of the difficult [programming] parts automatically.”

Gamalon CEO and cofounder Ben Vigoda showed MIT Technology Review a demo drawing app that uses their new method. The app is similar to one released by Google last year in that it predicts what a person is trying to sketch. However, unlike Google’s version, which relied on sketches it had previously seen to make predictions, Gamalon’s app relies on probabilistic programming to identify an object’s key features. Therefore, even if you draw a figure that’s different from what the app has previously seen, as long as it recognizes certain features — like how a square with a triangle on top is probably a house — it will make a correct prediction.

The two products Gamalon released show that this technique could have near-term commercial use. One product, the Gamalon Structure, using Bayesian program synthesis to recognize concepts from raw text, and it does so more efficiently than what’s normally possible. For example, after only receiving a manufacturer’s description of a television, it can determine its brand, product name, screen resolution, size, and other features. Another app, called Gamalon Match, categorizes products and prices in a store’s inventory. In both cases, the system can be trained quickly to recognize variations in acronyms or abbreviations.

Vigoda believes there are other possible applications, as well. For example, if equipped with a Beysian model of machine learning, smartphones or laptops wouldn’t need to share personal data with large companies to determine user interests; the calculations could be done effectively within the device. Autonomous cars could also learn to adapt to their environment much faster using this method of learning. The potential impact of smarter machines really can’t be overstated.

Peter Diamandis Thinks We’re Evolving Toward “Meta-Intelligence”


IN BRIEF

Peter Diamandis, founder and chairman of the XPRIZE Foundation, thinks the human species is headed for an evolutionary transformation.
The evolution of life has slowly unfolded over 3.5 billion years; but its pace has rapidly increased in recent years. Diamandis believes this heralds the next, exciting stages of human evolution.
FROM NATURAL SELECTION TO INTELLIGENT DIRECTION

In the next 30 years, humanity is in for a transformation the likes of which we’ve never seen before—and XPRIZE Foundation founder and chairman Peter Diamandis believes that this will give birth to a new species. Diamandis admits that this might sound too far out there for most people. He is convinced, however, that we are evolving towards what he calls “meta-intelligence,” and today’s exponential rate of growth is one clear indication.

In an essay for Singularity Hub, Diamandis outlines the transformative stages in the multi-billion year pageant of evolution, and takes note of what the recent increasing “temperature” of evolution—a consequence of human activity—may mean for the future. The story, in a nutshell, is this—early prokaryotic life appears about 3.5 billion years ago (bya), representing perhaps a symbiosis of separate metabolic and replicative mechanisms of “life;” at 2.5 bya, eukaryotes emerge as composite organisms incorporating biological “technology” (other living things) within themselves; at 1.5 bya, multicellular metazoans appear, taking the form of eukaryotes that are yoked together in cooperative colonies; and at 400 million years ago, vertebrate fish species emerge onto land to begin life’s adventure beyond the seas.

“Today, at a massively accelerated rate—some 100 million times faster than the steps I outlined above—life is undergoing a similar evolution,” Diamandis writes. He thinks we’ve moved from a simple Darwinian evolution via natural selection into evolution by intelligent direction.
“I believe we’re rapidly heading towards a human-scale transformation, the next evolutionary step into what I call a “Meta-Intelligence,” a future in which we are all highly connected—brain to brain via the cloud—sharing thoughts, knowledge and actions,” he writes.

Diamandis outlines the next stages of humanity’s evolution in four steps, each a parallel to his four evolutionary stages of life on Earth. There are four driving forces behind this evolution: our interconnected or wired world, the emergence of brain-computer interface (BCI), the emergence of artificial intelligence (AI), and man reaching for the final frontier of space.

In the next 30 years, humanity will move from the first stage—where we are today—to the fourth stage. From simple humans dependent on one another, humanity will incorporate technology into our bodies to allow for more efficient use of information and energy. This is already happening today.

The third stage is a crucial point.

Enabled with BCI and AI, humans will become massively connected with each other and billions of AIs (computers) via the cloud, analogous to the first multicellular lifeforms 1.5 billion years ago. Such a massive interconnection will lead to the emergence of a new global consciousness, and a new organism I call the Meta-Intelligence.
This brings to mind another futuristic event that many are eagerly anticipating: the technological singularity. “Within a quarter century, nonbiological intelligence will match the range and subtlety of human intelligence,” said notable futurist Ray Kurzweil, explaining the singularity.
“It will then soar past it because of the continuing acceleration of information-based technologies, as well as the ability of machines to instantly share their knowledge.” Kurzweil predicts that this will happen by 2045—within Diamandis’ evolutionary timeline. “The nonbiological intelligence created in that year will be one billion times more powerful than all human intelligence today.”

The fourth and final stage marks humanity’s evolution to becoming a multiplanetary species. “Our journey to the moon, Mars, asteroids and beyond represents the modern-day analogy of the journey made by lungfish climbing out of the oceans some 400 million years ago,” Diamandis explains.

Buckle up: we have an exciting future ahead of us.

New Device Can Ease Chronic Pain Without Drugs, Thanks to Brain Stimulation


IN BRIEF

This new method of pain treatment can prevent risky side-effects such as addiction, dependence, and overdose-related deaths – and it does so using electricity.

OPIOID MEDICINES

Abuse of prescription pain killers or opioid medicines is common. But then again, how else can you treat chronic pain? Unfortunately, addiction is a terrible side-effect that can lead to overdose-related deaths.

But now a research team from the University of Arlington seems to have found a better and more efficient solution: Electrical stimulation.

By delivering electrical currents—which can block pain signals at the spinal cord level—into a deep, middle brain structure, it might be possible to treat chronic pain without the intervention of drugs. At the same time, the technique can spur the release of dopamine, which helps with the emotional distress typically associated with long-term pain.

A SHOCKING STUDY

“This is the first study to use a wireless electrical device to alleviate pain by directly stimulating the ventral tegmental area of the brain,” said Yuan Bo Peng, UTA psychology professor. “While still under laboratory testing, this new method does provide hope that in the future we will be able to alleviate chronic pain without the side effects of medications.”

The team experimented with a custom-built wireless implant, which through electrical stimulation of the ventral tegmental area effectively reduced the sensation of pain, even blocking pain signals in the spinal cord.

This could greatly benefit the almost two million Americans who are addicted or dependent on opioid medicines. The Centers for Disease Control that 165,000 Americans died of opioid-related overdoses from 1999 to 2014.

“Until this study, the ventral tegmental area of the brain was studied more for its key role in positive reinforcement, reward and drug abuse,” said Peng. “We have now confirmed that stimulation of this area of the brain can also be an analgesic tool.”
