Paraplegic Kicks Off World Cup in Exoskeleton

https://i0.wp.com/images.latintimes.com/sites/latintimes.com/files/styles/large/public/2014/06/12/world-cup-kick.pngThe 2014 FIFA World Cup made history when it opened in Sao Paolo this week when a 29-year-old paraplegic man named Juliano Pinto kicked a soccer ball with the aid of a robotic exoskeleton. It was the first time a mind-controlled prosthetic was used in a sporting event, and represented the culmination of months worth of planning and years worth of technical development.

The exoskeleton was created with the help of over 150 researchers led by neuroscientist Dr. Miguel Nicolelis of Duke University, who’s collaborative effort was called the Walk Again Project. As Pinto successfully made the kick off with the exoskeleton, the Walk Again Project scientists stood by, watching and smiling proudly inside the Corinthians Arena. And the resulting buzz did not go unnoticed.

WorldCup_610x343Immediately after the kick, Nicolelis tweeted about the groundbreaking event, saying simply: “We did it!” The moment was monumental considering that only a few of months ago, Nicolelis was excited just to have people talking about the idea of a mind-controlled exoskeleton being tested in such a grand fashion. As he said in an interview with Grandland after the event:

Despite all of the difficulties of the project, it has already succeeded. You go to Sao Paulo today, or you go to Rio, people are talking about this demo more than they are talking about football, which is unbelievably impossible in Brazil.

Dr. Gordon Cheng, a team member and the lead robotics engineer of the Technical University of Munich, explained how the exoskeleton works in an interview with BBC News:

The basic idea is that we are recording from the brain and then that signal is being translated into commands for the robot to start moving.

https://i0.wp.com/blog.amsvans.com/wp-content/uploads/2014/02/the-world-cup-stadium-in-itaquera-brazil-e1393251187879.jpgThe result of many years of development, the mind-controlled exoskeleton represents a breakthrough in restoring ambulatory ability to those who have suffered a loss of motion due to injury. Using metal braces that were tested on monkeys, the exoskeleton relies on a series of wireless electrodes attached to the head that collect brainwaves, which then signal the suit to move. The braces are also stabilized by gyroscopes and powered by a battery carried by the kicker in a backpack.

Originally, a teenage paraplegic was expected to make the kick off. However, after a rigorous selection process that lasted many months, the 29 year-old Pinto was selected. And in performing the kickoff, he participated in an event designed to galvanize the imagination of millions of people around the world. It’s a new age of technology, friends, where disability is no longer a permanent thing,.

Friday the 13th “Honey Moon”

image

Friday the 13th may be a time for worry for the more superstitiously inclined. But for those who turned out to gaze at the night sky in the wee hours of the morning, it was also a chance to see something truly rare and beautiful. It’s what’s known as a “honey moon”, and one which won’t happen again in our lifetime.

Basically, a honey moon is something that happens during the summer solstice when the sun’s path across the sky at its highest during this month and the moon at its lowest, which keeps the lunar orb close to the horizon and makes it appear more amber than other full moons this year.

https://i0.wp.com/images.nationalgeographic.com/wpf/media-live/photos/000/806/cache/honey-moon-2014-solstice_80614_600x450.jpgThe amber colors are due to the scattering of longer wavelengths of light by dust and pollution in our atmosphere. As astronomer Raminder Signh Samra of the H.R. MacMillian Space Centre in Vancouver said:

It is a similar phenomenon as seen at sunset, when sunlight is scattered towards the red end of the spectrum, making the sun’s disk appear orange-red to the naked-eye.

The most spectacular part of the honey moon begins hours before midnight, due to an illusion by which the moon appears larger to sky-watchers when it’s near the horizon than when it hangs high in the sky. It reached it’s full phase last night at 12:13 am EDT, at least for those of us living in North America.

https://i0.wp.com/kimberlysnyder.net/blog/wp-content/uploads/2009/06/img_news_solstice_scheme11.gifScientists are not entirely sure what accounts for this optical illusion of a larger moon near the horizon, but they suspect it has something to do with the human mind trying to make sense of the moon’s proximity to more familiar objects like mountains, trees and houses in the foreground.

The monthly full moon always looks like a big disk, but because its orbit around the Earth is egg-shaped, there are times when the moon it is at its shortest distance from Earth (called perigee), some 362,065 km (224,976 miles) away. This month the perigee just happened to coincide with the full phase.

https://i0.wp.com/cdn.images.express.co.uk/img/dynamic/128/590x/moon-482025.jpgHence why it may have made it appear unusually large to some keen-eyed sky-watchers. As Samra explained:

The moon illusion should be more prominent during this full moon as it will graze closer to the horizon than at any other time of the year. This will make the moon appear more amber than other full moons of the year.

A full moon coinciding on Friday the 13th is not all that uncommon, occurring every three or so years. But having the combination of a honey moon and Friday the 13th is rare, last occurring on June 13, 1919. As for the next, we’ll have to wait until June 13, 2098, for the next one.

In short, stellar events like this one – where’s there’s a perfect conjunction between the occult and the night sky – only happen once every 80 or 90 years. So if you missed last night’s and are sad about it… Well, the good news is they are doing great things in medicine these days!

And if guys like Kurzweil are to be believed, clinical Immortality is just a few decades away. Until next time, be sure to keep your eyes to the heavens. Some interesting things happen there, apparently!

Frontiers in 3-D Printing: Frankenfruit and Blood Vessels

bioprinting3-D printing is pushing the boundaries of manufacturing all the time, expanding its repertoire to include more and more in the way of manufactured products and even organic materials. Amongst the many possibilities this offers, arguably the most impressive are those that fall into the categories of synthetic food and replacement organs. In this vein, two major breakthroughs took place last month, with the first-time unveiling of both 3-D printed hybrid fruit and blood vessels.

The first comes from a Dovetailed, UK-based design company which presented its 3-D food printer on Saturday, May 24th, at the Tech Food Hack event in Cambridge. Although details on how it works are still a bit sparse, it is said to utilize a technique known as “spherification” – a molecular gastronomy technique in which liquids are shaped into tiny spheres – and then combined with spheres of different flavors into a fruit shape.

frankenfruit1According to a report on 3DPrint, the process likely involves combining fruit puree or juice with sodium alginate and then dripping the mixture into a bowl of cold calcium chloride. This causes the droplets to form into tiny caviar-like spheres, which could subsequently be mixed with spheres derived from other fruits. The blended spheres could then be pressed, extruded or otherwise formed into fruit-like shapes for consumption.

The designers claim that the machine is capable of 3D-printing existing types of fruit such as apples or pears, or user-invented combined fruits, within seconds. They add that the taste, texture, size and shape of those fruits can all be customized. As Vaiva Kalnikaitė, creative director and founder of Dovetailed, explained:

Our 3D fruit printer will open up new possibilities not only to professional chefs but also to our home kitchens – allowing us to enhance and expand our dining experiences… We have been thinking of making this for a while. It’s such an exciting time for us as an innovation lab. Our 3D fruit printer will open up new possibilities not only to professional chefs but also to our home kitchens, allowing us to enhance and expand our dining experiences. We have re-invented the concept of fresh fruit on demand.

frankenfruit2And though the idea of 3-D printed fruit might seem unnerving to some (the name “Frankenfruit” is certainly predicative of that), it is an elegant solution of what to do in an age where fresh fruit and produce are likely to become increasingly rare for many. With the effects of Climate Change (which included increased rates of drought and crop failure) expected to intensify in the coming decades, millions of people around the world will have to look elsewhere to satisfy their nutritional needs.

As we rethink the very nature of food, solutions that can provide us sustenance and make it look the real thing are likely to be the ones that get adopted. A video of the printing in action is show below:


Meanwhile, in the field of bioprinting, researchers have experienced another breakthrough that may revolution the field of medicine. When it comes to replacing vital parts of a person’s anatomy, finding replacement blood vessels and arteries can be just as daunting as finding sources of replacement organs,  limbs, skin, or any other biological material. And thanks to the recent efforts of a team from Brigham and Women’s Hospital (BWH) in Boston, MA, it may now be possible to fabricate these using a bioprinting technique.

3d_bloodvesselsThe study was published online late last month in Lab on a Chip. The study’s senior author,  Ali Khademhosseini – PhD, biomedical engineer, and director of the BWH Biomaterials Innovation Research Center – explained the challenge and their goal as follows:

Engineers have made incredible strides in making complex artificial tissues such as those of the heart, liver and lungs. However, creating artificial blood vessels remains a critical challenge in tissue engineering. We’ve attempted to address this challenge by offering a unique strategy for vascularization of hydrogel constructs that combine advances in 3D bioprinting technology and biomaterials.

The researchers first used a 3D bioprinter to make an agarose (naturally derived sugar-based molecule) fiber template to serve as the mold for the blood vessels. They then covered the mold with a gelatin-like substance called hydrogel, forming a cast over the mold which was then  reinforced via photocrosslinks. Khademhosseini and his team were able to construct microchannel networks exhibiting various architectural features – in other words, complex channels with interior layouts similar to organic blood vessels.

bioprinting1They were also able to successfully embed these functional and perfusable microchannels inside a wide range of commonly used hydrogels, such as methacrylated gelatin or polyethylene glycol-based hydrogels. In the former case, the cell-laden gelatin was used to show how their fabricated vascular networks functioned to improve mass transport, cellular viability and cellular differentiation. Moreover, successful formation of endothelial monolayers within the fabricated channels was achieved.

According to Khademhosseini, this development is right up there with the possibility of individually-tailored replacement organs or skin:

In the future, 3D printing technology may be used to develop transplantable tissues customized to each patient’s needs or be used outside the body to develop drugs that are safe and effective.

Taken as a whole, the strides being made in all fields of additive manufacturing – from printed metal products, robotic parts, and housing, to synthetic foods and biomaterials – all add up to a future where just about anything can be manufactured, and in a way that is remarkably more efficient and advanced than current methods allow.

News from Space: ISS Sends First Transmission with Lasers

ISS In recent years, the International Space Station has become more and more media savvy, thanks to the efforts of astronauts to connect with Earthbound audiences via social media and Youtube. However, the communications setup, which until now relied on 1960’s vintage radio-wave transmissions, was a little outdated for this task. However, that has since changed with the addition of the Optical Payload for Lasercom Science (OPALS) laser communication system.

Developed by NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, OPALS is designed to test the effectiveness of lasers as a higher-bandwidth substitute for radio waves and deal with substantially larger information packages. As Matt Abrahamson, OPALS mission manager at NASA’s Jet Propulsion Laboratory, said in a recent video statement:

We collect an enormous amount of data out in space, and we need to get it all to the ground. This is an alternative that’s much faster than our traditional radio waves that we use to communicate back down to the ground.

nasa-opalsThe OPALS laser communication system was delivered to the ISS on April 20 by a SpaceX unmanned Dragon space freighter and is currently undergoing a 90-day test. For this test, the crew used the OPALS to transmit the “Hello, World” video from the ISS to a ground station on Earth. This was no simple task, since the station orbits Earth at an altitude of about 418 km (260 mi) at travels at a speed of 28,000 km/h (17,500 mph). The result is that the target is sliding across the laser’s field of view at an incredibly fast rate.

According to Bogdan Oaida, the OPALS systems engineer at JPL, this task was pretty unprecedented:

It’s like trying to use a laser to point to an area that’s the diameter of a human hair from 20-to-30 feet away while moving at half-a-foot per second. It’s all about the pointing.

However, the test went off without a hitch, with the 37 second-long video taking 3.5 seconds to transmit – much faster than previous downlink methods. Abrahamson said that the video, which is a lively montage of various communication methods, got its title as an homage to the first message output by standard computer programs.

earth-from-ISSThe OPALS system sought out and locked onto a laser beacon from the Optical Communications Telescope Laboratory ground station at the Table Mountain Observatory in Wrightwood, California. It then transmitted its own 2.5-watt, 1,550-nanometer laser and modulated it to send the video at a peak rate of 50 megabits per second. According to NASA, OPALS transmitted the video in 3.5 seconds instead of the 10 minutes that conventional radio would have required.

Needless to say, the astronauts who contribute to the ISS’s ongoing research programs are pretty stoked about getting this upgrade. With a system that is capable of transmitting exponentially more information at a faster rate, they will now be able to communicate with the ground more easily and efficiently. Not only that, but educational videos produced in orbit will be much easier to send. What’s more, the ISS will have a much easier time communicating with deep space missions in the future.

nasa-opals-5This puts the ISS in a good position to oversea future missions to Mars, Europa, the Asteroid Belt, and far, far beyond! As Abrahamson put it in the course of the video statement:

It’s incredible to see this magnificent beam of light arriving from our tiny payload on the space station. We look forward to experimenting with OPALS over the coming months in hopes that our findings will lead to optical communications capabilities for future deep space exploration missions.

And in the meantime, check out the video from NASA’s Jet Propulsion Laboratory, showing the “Hello World” video and explaining the groundbreaking implications of the new system:

The Future is Here: FDA Approves Human Suspended Animation

prometheus-cryotubeWe’ve all heard about it, read about it, and seen it in the movies. Suspended Animation. The ability to put someone in a tank and chill them to the point where their heart rate, breathing, and metabolism are reduced to an absolute minimum, preserving their life or prolonging it artificially. It’s a common science fiction concept, but could such a technique ever be made feasible? That is what a team of researchers from UPMC Presbyterian Hospital in Pittsburgh, with FDA approval, are attempting to answer.

The purpose of this research is to see if suspended animation can deliver on its main promise – namely, keeping a patient alive long enough to receive life-saving treatment or surgery. Oftentimes with disease and traumatic injuries, the difference between life and death is a simple matter of timing. And for those patients who simply cannot be helped with the current level of technology and pharmacology, it is also a race against time, trying to stay alive long enough to see science catch up with the illness.

EPRThis Emergency Preservation and Resuscitation (EPR) technique isn’t quite as extreme as what we’ve come to know from science fiction franchises. Instead of reducing a patient’s temperature to near-freezing levels, it involves reducing body temperature to 10 degrees Celsius (50 degrees Fahrenheit) by inserting a cannula into the aorta and flushing cold saline into the system. This will slow the blood flow, which will prevent the body from bleeding out and slow other biological processes as well.

So far, the result have been pretty subdued – with the EPR state of induced hypothermia only being sustainable for about two hours. While this isn’t as dramatic as some may have expected, that could easily provide enough time for surgeons to perform emergency lifesaving surgery. Trauma patients who suffer cardiac arrest have a 7% chance of survival, and administering this technique could have some very real and amazing implications.

suspended-animationThis technique was first tested by Peter Rhee in 2000 using 40 pigs, the results of which were published in 2006. After inflicting a lethal wound to simulate real-world trauma scenarios, the pigs were cooled down so the surgeons could operate then resuscitate them. While all of the control pigs died, the surgeons were able to save 90% of the pigs who had undergone suspension. None of the surviving pigs were reported to have sustained cognitive or physical impairment either.

And as per usual, animal testing is followed by human trials to see if success can be replicated. Due to the extremely time-sensitive and dire nature of the injuries of the test subjects, the FDA has declared that the surgeons will not require informed consent. As a precaution, the team took out advertisements to inform the public of the upcoming study, and even set up a website that would allow people to opt out, if desired. As of yet, nobody has opted out.

alien-stasis-suspended-animationThe plan for testing this process is for the team to the technique on 10 trauma patients whose injuries would be otherwise fatal. That group will be compared against 10 other patients who are not able to undergo EPR, due to the surgical team not being available. After the first increments of 10 EPR and 10 control patients, the technique will be analyzed and refined until enough data points have been collected which will allow them to analyze the efficacy of suspending life in this manner.

Should things work out, we can expect to see EPR becoming a regular part of modern medicine. And with further refinements, it may even be possible to place people in suspended animation for longer (or even indefinite) periods of time. If not, then I guess it will be just become one more of those many, many sci-fi fantasies that (like a patients in a story) will be put away until such time as the technology catches up to the fantasy.

Game of Thrones – Season Four Episode 9

got4This past weekend, the penultimate episode of Season Four of GOT aired, and an event which was a long time in coming was finally showed. Yes, after two seasons of build-up, the Wildlings under “King” Mance Rayder’s leadership, assaulted the Wall. Strangely, Mance was nowhere to be seen during this assault, but from the way they ended the episode, I’m sure we’ll be hearing from him soon enough. And as usual, I got some bones to pick with the writers, but not the same reasons others have.

After this weekend’s episode aired, a common thing I noticed from the critics was the statement that the attack on the Wall was no “Blackwater Bay”. Much like Season Two’s smash-up where Stannis and his armies lay siege to King’s Landing, the entire episode was dedicated to this one battle and those involved. And while it didn’t exactly have the same epic scope and grandeur as that battle, I think this is an unfair comparison.

One cannot expect a massive siege every season! It’s just not cost effective. No, in the end, I felt this battle fell a bit short because of the way they changed things around in the story, not to mention the way they shot the whole thing. By the time things really got started, I wasn’t sure if I was watching GOT or Lord of the Rings. Somehow, it felt like Peter Jackson was at the helm and not George RR Martin. But first, a recap…

The Watchers on the Wall:
GOT4_9_1The episode begins with Jon and Samwell standing atop the Wall and discussing love. Sam asks what it was like being with Ygritte, while once again lamenting the fact that he left Gilly at Moletown, where he suspects she died. Jon sends Sam below to get some rest, but he instead goes to the library to learn what Wildlings are known to do to their captives. Aemon finds him and they spend the time talking of lost love.

Going back outside, Sam comes to the gate in time to see Gilly knocking at Castle Black’s gate and asking to be let in. After convincing the Brother guarding it to let her in, he tells her they will never be apart again. Their reunion is interrupted when they hear a horn sound. From atop the Wall, Jon and the other brothers spot a massive forest fire looming in the distance. Mance’s signal to attack is issued, and thousands of Wildlings, giants and mammoths form up.

GOT4_9_2Under the command of Ser Alliser Thorne, the Brothers begin preparing their defenses, and he takes a moment to let Jon know that he will be equal to the task of leading them. The mammoths move forward to the gate while other Wildlings begin scaling the Wall. Sam places Gilly in a chamber below and locks the door, telling her she must hide and he must stand with his Brothers. He kisses her goodbye, and she makes him promise he won’t die.

South of the Wall, Ygritte, Tormund, the Thenns and their raiding party are preparing to make their assault. While they wait for Mance to send the signal – “the biggest fire the North has ever seen”. When they spot it, they launch their attack on Castle Black’s gates. Sam and the others let loose on them with arrows, but are quickly overtaken as the Wildling party moves in and scales the short walls that guard the southern approach.

GOT4_9_4Hearing of the attack on the Castle, Thorne goes below to organize the defense, leaving Slynt in charge. Below, two giants lead a mammoth to the gate and hitch ropes from its harness the doors, intending to pull it off. Slynt quickly proves unequal to the task of leading the defense and begins muttering about how it was so much easier commanding the Kingsguard. Grenn then tricks Slynt and tells him he’s needed below too, which leaves Jon in charge.

Relying on the lessons he learned during his time among them, Jon has his archers fire arrows onto those scaling the Wall and drops barrels on those at the gate. Below, the battle in Castle Black’s courtyard turns bad. The brothers lose many men, Thorne is injured and incapacitated, and Slynt runs and locks himself in the same room as Gilly. Jon decides to go below with Grenn and some others, and orders Eddison to unleash fire on the mammoths.

GOT4_9_3This he does, which kills most of the Wildlings and sends the mammoth running. One of the two giants is then killed by a Scorpion up on the Wall, sending the other into a rage and leading him to begin prying the gate open with his bare hands. Jon arrives below and tells Grenn and the others to get to the gate an hold it at all costs. He then has Sam unlock Ghost from his cage and begins fighting his way through the Wildlings.

In a pitch fight, Jon kills Styr (the leader of the Thenn party) with a blacksmith’s hammer and comes face to face with Ygritte, who has her bow drawn on him. She hesitates to shoot him, and is then shot with an arrow through the chest by Olly, the young boy who mans the elevator. She dies, repeating the same words she said to him, time and time again: “You know nothing, Jon Snow.” Inside the Wall gate, the giant breaks through and attacks Grenn and his brothers. They die holding the giant off.

got4_9_5Up top, Eddis sees that they only have the few Wildlings scaling the Wall to deal with, and orders that they drop the “Scythe” – a large metal blade at the end of a chain that combs the wall when released. This kills the remaining attackers, and the rest fall back. In the courtyard, Tormund is wounded and captured, and Jon orders him put in chains. Sam returns below to find Gilly safe, and Slynt cowering in the corner.

Surveying the damage, Jon tells Sam that this was just the first assault, and that Mance will break through before long if they allow him to continue. He then tells Sam that he will meet with Mance, during which time he will attempt to kill him so that the Wildlings once again become divided. They head to for the gate, where they find the bodies of Grenn, the giant, and the others who died holding it. Sam orders the gate opened and says goodbye to Jon.

Summary:
Well, the episode certainly was fun and entertaining. One can’t deny that an incredible amount of time, effort, and good direction went into making it. And it did manage to capture the spirit, if not the letter, of the battle as it was described in the book. But as usual, there were some things that bothered to me that had to do with changes, not to mention how those changes affected the feel and flow of things. Here’s what they were, in chronological order…

First, there was no last-minute reunion between Sam and Gilly. She had been at the castle for some time, and a romance had not quite budded between them. Second, Tormund, Ygritte and the Wildling raider party had already assaulted Castle Black at this point in advance of Mance’s main assault. Having struck at Castle Black days before, they were thwarted by a great deal of ingenuity and booby traps, which were installed thanks to Jon’s help.

Third, there was none of this shuffling around of commanders in the novels. While it is true that Thorne and Slynt did not trust Jon, he was still put in charge of the Wall’s defenses since he had intimate knowledge of Mance’s plan of attack, and because Aemon on his Brothers vouched for him. It was not the case that he had it thrust on him because Thorne had to go below, or because Slynt was a coward. This last aspect they really played up, and it felt like it was just to give us someone to hate.

Fourth, two decidedly cheesy moments happened in this battle. The first was where Sam narrowly managed to get his crossbow loaded in time to take down a Wildling. The second – and by far, the worst – was Ollie going from a frightened little boy who couldn’t stand the sound of fighting to grabbing a bow and killing Ygritte with it. This more than anything was like a scene out of Jackson’s LOTR. It wasn’t nearly as bad as Legolas riding a shield down a set of steps like it was a skateboard, but still!

Fifth, Tormund was not taken prisoner during the battle. After losing his attack force south of the Wall, he fled north again and began rallying Wildlings later. Ever since, even as far as book V, he has not been heard from. And finally, Jon Snow did not decide to venture out and assassinate Mance once the battle was over. In fact, it was Slynt’s idea to send him out in the hopes that he would die while attempting to kill Mance.

You see, after the battle, Slynt and his allies were still nominally in charge since no new Lord Commander had been elected. And he would go on to be a pain in Jon’s ass since he didn’t trust him and saw him as a threat to his possible leadership. However, the way they’ve presented him here, as an incompetent coward, is melodramatic to say the least. It also kind of complicated the plot now, since Slynt disgraced himself for all to see.

In short, it felt like they were trying to sex things up from the original material; but really, I only felt like they dumbed it down. Many things they did get right, like the way the giants penetrated into the gate, or how Ygritte died with Jon standing over her and crying. They also captured the defenders sense of desperation, knowing that they were vastly outnumbered, but still protecting by the Wall’s defenses. And I have to say that this was one episode this season that didn’t bore or disappoint the hell out of me.

Still… where the hell was Mance this whole time? Has anyone else noticed he completely disappeared after his brief appearance last season? He better show up next week, as he’s kind of intrinsic to the plot!

The Birth of AI: Computer Beats the Turing Test!

turing-statueAlan Turing, the British mathematician and cryptogropher, is widely known as the “Father of Theoretical Computer Science and Artificial Intelligence”. Amongst his many accomplishments – such as breaking Germany’s Enigma Code – was the development of the Turing Test. The test was introduced by Turing’s 1950 paper “Computing Machinery and Intelligence,” in which he proposed a game wherein a computer and human players would play an imitation game.

In the game, which involves three players, involves Player C  asking the other two a series of written questions and attempts to determine which of the other two players is a human and which one is a computer. If Player C cannot distinguish which one is which, then the computer can be said to fit the criteria of an “artificial intelligence”. And this past weekend, a computer program finally beat the test, in what experts are claiming to be the first time AI has legitimately fooled people into believing it’s human.

eugene_goostmanThe event was known as the Turing Test 2014, and was held in partnership with RoboLaw, an organization that examines the regulation of robotic technologies. The machine that won the test is known as Eugene Goostman, a program that was developed in Russia in 2001 and goes under the character of a 13-year-old Ukrainian boy. In a series of chatroom-style conversations at the University of Reading’s School of Systems Engineering, the Goostman program managed to convince 33 percent of a team of judges that he was human.

This may sound modest, but that score placed his performance just over the 30 percent requirement that Alan Turing wrote he expected to see by the year 2000. Kevin Warwick, one of the organisers of the event at the Royal Society in London this weekend, was on hand for the test and monitored it rigorously. As Deputy chancellor for research at Coventry University, and considered by some to be the world’s first cyborg, Warwick knows a thing or two about human-computer relations

kevin_warwickIn a post-test interview, he explained how the test went down:

We stuck to the Turing test as designed by Alan Turing in his paper; we stuck as rigorously as possible to that… It’s quite a difficult task for the machine because it’s not just trying to show you that it’s human, but it’s trying to show you that it’s more human than the human it’s competing against.

For the sake of conducting the test, thirty judges had conversations with two different partners on a split screen—one human, one machine. After chatting for five minutes, they had to choose which one was the human. Five machines took part, but Eugene was the only one to pass, fooling one third of his interrogators. Warwick put Eugene’s success down to his ability to keep conversation flowing logically, but not with robotic perfection.

Turing-Test-SchemeEugene can initiate conversations, but won’t do so totally out of the blue, and answers factual questions more like a human. For example, some factual question elicited the all-too-human answer “I don’t know”, rather than an encyclopaedic-style answer where he simply stated cold, hard facts and descriptions. Eugene’s successful trickery is also likely helped by the fact he has a realistic persona. From the way he answered questions, it seemed apparent that he was in fact a teenager.

Some of the “hidden humans” competing against the bots were also teenagers as well, to provide a basis of comparison. As Warwick explained:

In the conversations it can be a bit ‘texty’ if you like, a bit short-form. There can be some colloquialisms, some modern-day nuances with references to pop music that you might not get so much of if you’re talking to a philosophy professor or something like that. It’s hip; it’s with-it.

Warwick conceded the teenage character could be easier for a computer to convincingly emulate, especially if you’re using adult interrogators who aren’t so familiar with youth culture. But this is consistent with what scientists and analysts predict about the development of AI, which is that as computers achieve greater and greater sophistication, they will be able to imitate human beings of greater intellectual and emotional development.

artificial-intelligenceNaturally, there are plenty of people who criticize the Turing test for being an inaccurate way of testing machine intelligence, or of gauging this thing known as intelligence in general. The test is also controversial because of the tendency of interrogators to attribute human characteristics to what is often a very simple algorithm. This is unfortunate because chatbots are easy to trip up if the interrogator is even slightly suspicious.

For instance, chatbots have difficulty answering follow up questions and are easily thrown by non-sequiturs. In these cases, a human would either give a straight answer, or respond to by specifically asking what the heck the person posing the questions is talking about, then replying in context to the answer. There are also several versions of the test, each with its own rules and criteria of what constitutes success. And as Professor Warwick freely admitted:

Some will claim that the Test has already been passed. The words Turing Test have been applied to similar competitions around the world. However this event involved more simultaneous comparison tests than ever before, was independently verified and, crucially, the conversations were unrestricted. A true Turing Test does not set the questions or topics prior to the conversations. We are therefore proud to declare that Alan Turing’s Test was passed for the first time on Saturday.

artificial_intelligence1So what are the implications of this computing milestone? Is it a step in the direction of a massive explosion in learning and research, an age where computing intelligences vastly exceed human ones and are able to assist us in making countless ideas real? Or it is a step in the direction of a confused, sinister age, where the line between human beings and machines is non-existent, and no one can tell who or what the individual addressing them is anymore?

Difficult to say, but such is the nature of groundbreaking achievements. And as Warwick suggested, an AI like Eugene could be very helpful to human beings and address real social issues. For example, imagine an AI that is always hard at work on the other side of the cybercrime battle, locating “black-hat” hackers and cyber predators for law enforcement agencies. And what of assisting in research endeavors, helping human researchers to discover cures for disease, or design cheaper, cleaner, energy sources?

As always, what the future holds varies, depending on who you ask. But in the end, it really comes down to who is involved in making it a reality. So a little fear and optimism are perfectly understandable when something like this occurs, not to mention healthy.

Warning Signs from the Future

future-signs-02From bioenhancements becoming the norm, to people constantly wired into augmented reality; from synthetic organs to synthetic meat; driverless taxis to holograms and robot helpers – the future is likely to be an interesting-looking place. That’s the subject in a new Tumblr called Signs from the Near Future, where designer Fernando Barbella explores what signage will look like when we have to absorb all of these innovations into human culture.

Taking its cue from what eager startups and scientists predict, Barbella’s collection of photos looks a few decades into the future where dramatic, sci-fi inspired innovations have become everyday things. These include things like drones becoming a regular thing, driverless taxis (aka. robotaxis) and synthetic meat becoming available, high-tech classrooms servicing the post-humans amongst us, and enhancements and implants becoming so common they need to be regulated and monitored.

future-signs-01Barbella says that the project was inspired by articles he’s read on topics like nanomedicine, autonomous cars, and 3-D food printing, as well as classic books (Neuromancer, Fahrenheit 51), movies (Blade Runner, Gattaca), music (Rage Against The Machine), and TV shows (Fringe, Black Mirror). The designer chose to focus on signs because he figures that we’ll need a little guidance to speed up our learning curves with new technology. As he put it during an interview via email:

New materials, mashups between living organisms and nanotechnologies, improved capabilities for formerly ‘dumb’ and inanimate things . . . There’s lots of awesome things going on around us! And the fact is all these things are going to cease being just ‘projects’ to became part of our reality at any time soon. On the other hand, I chose to express these thing by signs deployed in ordinary places, featuring instructions and warnings because I feel that as we increasingly depend on technology, we will probably have less space for individual judgment to make decisions.

future-signs-07Some of the signs – including one thanking drivers for choosing to ride on a solar panel highway – can be traced back to specific news articles or announcements. The solar highway sign was inspired by a solar roadways crowdfunding campaign, which has so far raised over $2 million to build solar road panels. However, rather than focus on the buzz and how cool and modern such a development would be, Barbella chose to focus on what such a thing would look like.

At the same time, he wanted the pictures to serve as a sort of cautionary tale about the ups and down of the future. As he put it:

I feel that as we increasingly depend on technology, we will probably have less space for individual judgment to make decisions. …I’ve sticked to a more ‘mundane’ point of view, imagining that the people or authorities of any given county would be probably quite grateful for having the chance of transforming all that traffic into energy.

future-signs-03He says he wants his signs to not just depict that momentum and progress, but to reflect the potentially disturbing aspects of those advances as well. Beyond that, Barbella sees an interesting dynamic in the public’s push and pull against what new technology allows us to do. Though the technology grants people access to information and other cultures, it also poses issues of privacy and ethics that hold that back. As a result, privacy concerns are thus featured in the collection in a number of ways.

This includes warning people about “oversharing” via social media, how images snapped using contact display lenses will be shared in real-time with authorities, or how certain neighorhoods are drone patrolled. His images offer a look at why those issues are certain to keep coming — and at the same time, why many will ultimately fall aside. Barbella also stated that has more future signs in the queue, but he says that he’ll stop the moment they start to feel forced.

future-signs-05You have to admit, it does capture the sense of awe and wonder – not to mention fear and anxiety – of what our likely future promises. And as the saying goes, “a picture is worth a thousands words”. In this case, those words present a future that has one foot in the fantastical and another in the fearful, but in such a way that it seems entirely frank and straighforward. But that does seem to be the way the future works, doesn’t it? Somehow, it doesn’t seem like science fiction once it becomes a regular part of “mundane” reality.

The Future is Here: Black Hawk Drones and AI pilots

blackhawk_droneThe US Army’s most iconic helicopter is about to go autonomous for the first time. In their ongoing drive to reduce troops and costs, they are now letting their five-ton helicopter carry out autonomous expeditionary and resupply operations. This began last month when the defense contractor Sikorsky Aircraft, the company that produces the UH-60 Black Hawk – demonstrated the hover and flight capability in an “optionally piloted” version of their craft for the first time.

Sikorsky has been working on the project since 2007 and convinced the Army’s research department to bankroll further development last year. As Chris Van Buiten, Sikorsky’s vice president of Technology and Innovation, said of the demonstration:

Imagine a vehicle that can double the productivity of the Black Hawk in Iraq and Afghanistan by flying with, at times, a single pilot instead of two, decreasing the workload, decreasing the risk, and at times when the mission is really dull and really dangerous, go it all the way to fully unmanned.

blackhawk_drone1The Optionally Piloted Black Hawk (OPBH) operates under Sikorsky’s Manned/Unmanned Resupply Aerial Lifter (MURAL) program, which couples the company’s advanced Matrix aviation software with its man-portable Ground Control Station (GCS) technology. Matrix, introduced a year ago, gives rotary and fixed-wing vertical take-off and landing (VTOL) aircraft a high level of system intelligence to complete missions with little human oversight.

Mark Miller, Sikorsky’s vice-president of Research and Engineering, explained in a statement:

The autonomous Black Hawk helicopter provides the commander with the flexibility to determine crewed or un-crewed operations, increasing sorties while maintaining crew rest requirements. This allows the crew to focus on the more ‘sensitive’ operations, and leaves the critical resupply missions for autonomous operations without increasing fleet size or mix.

Alias-DarpaThe Optionally Piloted Black Hawk fits into the larger trend of the military finding technological ways of reducing troop numbers. While it can be controlled from a ground control station, it can also make crucial flying decisions without any human input, relying solely on its ‘Matrix’ proprietary artificial intelligence technology. Under the guidance of these systems, it can fly a fully autonomous cargo mission and can operate both ways: unmanned or piloted by a human.

And this is just one of many attempts by military contractors and defense agencies to bring remote and autonomous control to more classes of aerial vehicles. Earlier last month, DARPA announced a new program called Aircrew Labor In-Cockpit Automation System (ALIAS), the purpose of which is to develop a portable, drop-in autopilot to reduce the number of crew members on board, making a single pilot a “mission supervisor.”

darpa-alias-flight-crew-simulator.siMilitary aircraft have grown increasingly complex over the past few decades, and automated systems have also evolved to the point that some aircraft can’t be flown without them. However, the complex controls and interfaces require intensive training to master and can still overwhelm even experienced flight crews in emergency situations. In addition, many aircraft, especially older ones, require large crews to handle the workload.

According to DARPA, avionics upgrades can help alleviate this problem, but only at a cost of tens of millions of dollars per aircraft type, which makes such a solution slow to implement. This is where the ALIAS program comes in: instead of retrofitting planes with a bespoke automated system, DARPA wants to develop a tailorable, drop‐in, removable kit that takes up the slack and reduces the size of the crew by drawing on both existing work in automated systems and newer developments in unmanned aerial vehicles (UAVs).

Alias_DARPA1DARPA says that it wants ALIAS to not only be capable of executing a complete mission from takeoff to landing, but also handle emergencies. It would do this through the use of autonomous capabilities that can be programmed for particular missions, as well as constantly monitoring the aircraft’s systems. But according to DARPA, the development of the ALIAS system will require advances in three key areas.

First, because ALIAS will require working with a wide variety of aircraft while controlling their systems, it will need to be portable and confined to the cockpit. Second, the system will need to use existing information about aircraft, procedures, and flight mechanics. And third, ALIAS will need a simple, intuitive, touch and voice interface because the ultimate goal is to turn the pilot into a mission-level supervisor while ALIAS handles the second-to-second flying.

AI'sAt the moment, DARPA is seeking participants to conduct interdisciplinary research aimed at a series of technology demonstrations from ground-based prototypes, to proof of concept, to controlling an entire flight with responses to simulated emergency situations. As Daniel Patt, DARPA program manager, put it:

Our goal is to design and develop a full-time automated assistant that could be rapidly adapted to help operate diverse aircraft through an easy-to-use operator interface. These capabilities could help transform the role of pilot from a systems operator to a mission supervisor directing intermeshed, trusted, reliable systems at a high level.

Given time and the rapid advance of robotics and autonomous systems, we are likely just a decade away from aircraft being controlled by sentient or semi-sentient systems. Alongside killer robots (assuming they are not preemptively made illegal), UAVs, and autonomous hovercraft, it is entirely possible wars will be fought entirely by machines. At which point, the very definition of war will change. And in the meantime, check out this video of the history of unmanned flight:

Skyrim – Game of Thrones Theme!

skyrim_GOTIt was bound to happen sooner or later, what with Season Four of GOT coming to an end and the current popular obsession with mash-ups. In this video, Vimeo user Brady Wold mashed up the fantasy game Elders Scrolls V: Skyrim with the intro theme from Game of the Thrones to create something very watchable and fun. Using locations within the realm of Tamriel, the animation sweeps across the lands of Skyrim and watches cities like Whiterun, Riften, and others assemble themselves from the ground up.

Ever since it’s release in 2011, this RPG has been renowned for featuring elements that are quite similar to the HBO series and the fictional A Song of Ice and Fire universe on which it is based. This includes sword and sorcery, medieval history and clothing, dragons, epic fantasy, and an a common sense of aesthetics. And if that’s not enough for you, there’s a ton of GOT mods that can be uploaded to the game to add content and items from the series.

Skyrim_longclawFor instance, I myself experimented by adding weapons like Ice (Eddard Stark’s huge ass sword), Longclaw (Jon Snow’s bastard sword) and Needle (Arya Stark’s pigsticker) into the game with the “GOT Weapons Pack”. You can also download an “Arya Stark Follower” mod that has a version of this young character follow you around and assist you, and there are numerous others that allow for you to integrate livery and standards from the GOT universe into the game.

And there’s even a mod that makes it so whenever you fire up Skyrim, instead of seeing the opening Bethesda logo, this video animation plays. New ones emerge every week, including ones from the LOTR franchise and other fantasy universes. It kind of makes you wonder why the studios even bother making games anymore! Couldn’t an army of moderators simply build MMORPGs online from now on that would cut out the video game makers altogether?

I should keep my voice down, don’t want to encourage said folks. Some of the mods they created are already on the border between and bad taste. Lord only knows what kind of stuff they’d allow for if they had total freedom! In the meantime, enjoy the video:
