How the Atomic Age Gave Us Robot Surgeons

Your next surgery may be performed by a robot. It will be controlled by a doctor in the room, or perhaps by one across the country. What’s truly extraordinary, though, is where these surgery robots came from. Their origin stories stretch back to the radioactive labs of the atomic age.

Atomic Servants

As the US emerged from World War II, the newly-formed Atomic Energy Commission set out to repurpose and expand its nuclear programs to include uses here at home, like nuclear power and medicine.

All that atomic research meant exposing more and more researchers to deadly hazardous materials on an every-day basis—so it’s no surprise the Commission was interested in developing new tools that would let scientists work with radioactive material. It began commissioning leaders in robotics to build machines that could do the work while protecting the human body directing it—and a new era in robotics was born.

“Incredible engineering achievements occurred in a brief period of 15 years,” writes Bijoy Ghosh about the era. Before, says Ghosh, a nuclear technician might shield himself with a periscope or a wall made out of lead bricks—seriously low-tech protection considering how dangerous the work was. Now, the Commission wanted to develop a better, safer way—by using what amounted to a mechanical version of the scientist’s own arms and hands.

These weren’t robots. They were machines that translated the movements of a human body into mechanical terms somewhere else—and even returned “force feedback” to the human so that they could deftly work with materials from far away. The engineer Raymond Goertz, who worked at the Argonne National Laboratory, developed something called a “teleoperated articulated arm,” often described as a Master-Slave Manipulator, or MSM.

1250875518235434644.jpg


It was, essentially, a handset gripped by the human that attached to a mechanical version at the other end—the human could manipulate the robotic hand with the motion of his own. At the Nevada Test site, dozens of these manipulator arms were soon installed in long hallways lined with “hot cells,” where radioactive material could be safely manipulated by a human in khakis and a button up from behind a protective window.

1250875518613727892.jpg


Many of these machines have been forgotten, but CyberneticZoo’s Reuben Hoggett maintains an incredible archive of images and articles about Goertz and his contemporaries on his site.

Other researchers in the field, like GE’s John Payne, were on to the same idea. Luckily, Payne’s 1948 master-slave-manipulator is the subject of this fantastic video preserved by the British Pathé.

Another preserved video reel from 1960 shows a nuclear manipulator serving tea and lighting a woman’s cigarette:

1250875518866842772.gif


Even though they often get overlooked, these complex, experimental machines are the ancestors to a huge number of technologies in our own world—from the Apple Watch’s taptic engine to the idea of “telepresence” in general. The Atomic Energy Commission had perhaps unintentionally spurred decades-worth of development on how humans telecommute.

“Their fundamental research on remote manipulators is still quite valid today,” says Ghosh. “Sixty years later we are still seeing ideas that this invention spawned,” adds Reuben Hoggett.

A robot with a bellyache

If these massive, pulley-draped machines seemed alien, things would only get weirder from there. The idea of exoskeletons and master-slave manipulators exploded throughout pop culture—it was an idea too incredible not to immortalize.

Meanwhile, companies like GE continued developing robotic manipulators for atomic research—not always to great success. One notable failure was a 170,000-pound Beetle, immortalized by a Popular Science article from 1962 that described the tank-like manipulator—inside which a small human controlled its movements—as the biggest robot ever made. Here’s an incredible photo of Beetle unearthed by Kotaku:

1250875518918553492.jpg


“If H-bombs struck, he could dash to the destruction zone to rescue injured people and scrape away the worst of the fallout dust,” exclaimed Popular Science.

But even the enthusiastic-til-the-end Popular Science writers couldn’t ignore Beetle’s shortcomings. “When PS Chief Photographer Bill Morris and I first saw the Beetle, it wasn’t doing anything but sitting on a hangar floor,” the writer explained “They couldn’t start the engine.” Beetle was a gargantuan, oil-seeping “robot with a bellyache.”

It turned out that building bigger and bigger versions of Goertz’s old manipulators wasn’t the answer—it was making them smaller was. Soon, other government agencies were working on smaller, defter versions of the same idea. A NASA researcher named Scott Fisher was developing virtual reality headsets and hand-worn interfaces that could interact with these virtual worlds. He even made up a word for what NASA was studying: telepresence.

Collaborating with a surgeon from Stanford on how these VR systems could be used for surgeons—and working with other robotics experts, developer a manipulator arm that could perform real surgery.

Soon, as Russel A. Faust explains in Robotics in Surgery, the idea of telepresence surgery was blooming—in 1985, the first robotic-assisted surgery took place using the PUMA 560 robotic surgical arm, an early robotic surgical arm. Today robotic arms, telepresence machines, and tactile interfaces are used in everything from surgery to business meetings. We see them in action movies like the Avengers and even Star Wars.

1250875518999179924.jpg


It’s such a prevalent idea that we don’t think very much about where it came from—it’s almost as if it’s been there all along. But it’s amazing to realize that this futuristic technology leads back to the experimental designs of a few researchers working in the desert in the 1950s.

I watched it twice, the perks of working in a hospital and sometimes the emergency wing, you get used to stuff like this:partay:. It's amazing though, the progress made with robotic medical equipment - exoskeletons are big right now with the Military.



A Weird New Supercooled Material Crystallizes and Glows When Touched


Perhaps you’re familiar with the strangeness of supercooled water: It stays liquid well below water’s freezing point until you give it a whack, and bam, it suddenly turns into solid ice. You’re probably less familiar diketopyrrolopyrrole (DPP) derivatives, which has similar but also odder properties.

In a new study, scientists introduce DPP8, one particular derivative that can be supercooled to 200 degrees F below its freezing point. When lightly touched, DPP8 suddenly crystallizes, not unlike water turning into ice. The yellow crystals glow under ultraviolet light.

In other words, DPP8 is an extremely sensitive color-changing touch sensor. The researchers suggest it could have applications in electronics or medicine. In the meantime, though, it’s also pretty fun to drawn on.

Ultra HD Blu-ray discs are finally ready to bring 4K movies to your home theater | TechHive

blu-ray-player-100584964-large.jpg


Pretty soon Amazon, Netflix, and hard drives packed with video files won't be your only options for watching 4K "Ultra HD" content. The Blu-ray Disc Association (BRDA) recently announced the specification for Ultra HD Blu-ray discs was complete.

Licensing for the new spec is expected to take place this summer, with new Ultra HD discs and players to roll out after that. The BRDA did not say when we might see hardware and discs on store shelves, but a launch in time for the holidays is a good bet. Panasonic showed off a 4K Blu-ray player prototype at CES, and Hollywood has yet to meet a new disc format it didn't like.

The impact on you at home: The convenience of streaming services can't be beat, but Ultra HD Blu-ray discs may offer a better 4K experience depending on your Internet connection. To get the best picture out of UHD discs you'll need a 4K TV with support for HDMI 2.0. This shouldn't be a problem for newer UHD TVs, and many early adopters should have received an HDMI 2.0 upgrade already.

Also be on the lookout for an HDMI firmware update to the HDMI 2.0a spec announced in April. Without it, your TV won't be able to support HDR from UHD Blu-ray.

What's new
UHD Blu-ray brings a number of improvements compared to current 1080p Blu-ray discs. First and foremost, UHD Blu-ray supports resolutions up to 3840-by-2160, the 4K/UHD standard for home theaters, which is four times the resolution of 1080p.

UHD Blu-ray also promises an expanded color range, high dynamic range support, and the ability to deliver high frame rate content.

The BRDA also made reference to support for something it calls an "optional digital bridge feature" that will allow you to view Ultra HD Blu-ray content across your devices at home and on-the-go. It's not clear if this is an UltraViolet-style offering or something similar to the digital copies that are included with some DVDs and Blu-ray discs now.

To contain all those new picture enhancements and features, the new UHD Blu-ray discs will be able to hold up to 66GB of data in dual layer format, and up to 100GB in triple.

The UHD Blu-ray spec also requires 4K Blu-ray players to be backwards compatible with regular Blu-ray discs.

World's First Medical Radioactive Isotope Was Handled in Shirt and Tie

1251758831764448399.jpg


Oak Ridge National Laboratory has just released in high resolution this amazing historical photo. According to ORNL, in this photograph you can see two scientists as they remove the world’s first radioactive isotope produced for medical use from Oak Ridge’s Graphite Reactor, on August 2nd 1946. In compulsory collar and tie.

The man on the right is targeting a Cutie Pie handheld radiation detector toward the radioactive material. The Carbon 14 sample produced in the reactor was then shipped later to Brand Free Skin and Cancer Hospital in St. Louis.
 
An Artificial Intelligence Is Being Taught To Simulate Anger

1252096628074465575.png


Data scientists from New Zealand are teaching an AI to learn anger. Sounds crazy, but the idea is to help companies deal with common customer complaints.

Tech firm Touchpoint Group is using machine learning to help its AI system recognize — and even simulate — anger. Called Radiant (a name taken from Isaac Asimov’s Foundation series), the purpose of the AUD $500,000 project (USD $404,000) is to develop an automated system that can defuse angry customer service calls. Once complete, the system will be capable of generating over a hundred million (!) angry interactions. Touchpoint’s data scientists are hoping to build a system that can autonomously find the best response to typical customer complaints.

But as The Telegraph’s Olivia Goldhill explains, Radiant won’t be capable of actually experiencing genuine anger. It can only be programmed to mimic and repeat these nasty conversations. As Stuart Armonstrong from the Future of Humanity Institute told her:

There’s not much variety in human anger. If someone’s angry they’ll just hurl insults at you, there’s not much subtlety of interaction so you don’t have to code anything complicated. Anger is easy to imitate without having to go into depth.

Touchpoint, which expects to roll-out a live system by the end of the year, is targeting big banks, telcos, and insurance companies as potential customers.

Sounds about right.

The Final Oculus Rift Will Need an $800 Gaming PC

1253485201200899875.jpg


We’ve always known that good virtual reality wouldn’t come cheap. From the beginning, Oculus used beefy gaming PCs to show off its VR headset. Now, the company is revealing the specs you’ll need to get those experiences on the final Oculus Rift—and it looks like you’ll be spending $800+ just for the desktop computer.

Oculus says these are the recommended specs “for the full Rift experience”:

  • NVIDIA GTX 970 / AMD 290 equivalent or greater
  • Intel i5-4590 equivalent or greater
  • 8GB+ RAM
  • Compatible HDMI 1.3 video output
  • 2x USB 3.0 ports
  • Windows 7 SP1 or newer
Honestly, that’s not too bad—considering Oculus also just revealed that the final Rift needs to push 400 million pixels per second. With two displays inside running at a combined resolution of 2160 x 1200, refreshing 90 times per second, plus some additional headroom (so you can move your head around without seeing things that haven’t loaded yet), Oculus says the Rift requires approximately three times the GPU performance you normally need to play games at 1080p.

But that means you’ll be paying a good bit if you want to jump in. I just whipped together a quick PC system build at PCPartPicker with some of the cheapest (yet tried and true) components you can get, and it added up to just over $800 after discounts and rebates.

Yeah, yeah, these are Oculus’ recommended specs, not absolute requirements, so you could probably go cheaper if needed. (Also, prices may come down by the time the Rift ships.) But remember that virtual reality has way less wiggle room for performance to dip. If a traditional video game drops under a certain amount of frames per second, it’s a little choppy. If a VR experience drops frames, it can totally destroy the illusion or even make you sick.

What about plugging the Oculus Rift into a laptop? Bad news: “almost no current laptops have the GPU performance for the recommended spec,” says the company’s chief architect.
 
Watch These Nimble Robotic Arms Perform Surgery On A Grape

1253534445110517058.gif


Robots are poised to revolutionize surgery, as demonstrated by this astounding—and even touching—promotional video showcasing the da Vinci Surgical System as it sutures a damaged grape.

There’s a reason these robotic arms’ actions look human-like. Though it’s referred to as a robot, the system can’t move or operate autonomously; a surgeon is 100% in control. The technology is designed to expand a surgeon’s capabilities and make operations less invasive.


Unlike humans, these robotic hands aren’t shaky. The company that designed the system, Intuitive Surgical, says they’re also more flexible, allowing them to fit through smaller incisions.

The jury is still out on whether robot-assisted surgeries are more effective than ones performed directly by human hands. What’s more, there are some serious liability issues to be sorted out before these systems get rolled out en masse.
 
This Tiny Battery Could Make Small Chips Entirely Independent

by7tf9teja6xyo646hvz.jpg


While chips have gotten increasingly smaller, even low-power silicon usually uses off-chip power supplies because shrinking batteries down is difficult. This new super-small battery could finally put power supplies on the chip—and tiny computational systems anywhere you can imagine.

The new battery has been produced using a combination of 3D holographic lithography and 2D photolithography by researchers from the University of Illinois at Urbana-Champaign. “We utilized 3D holographic lithography to define the interior structure of electrodes and 2D photolithography to create the desired electrode shape,” explains Hailong Ning, one of the researchers, to PhysOrg. The resulting tiny lithium-ion battery can easily enough muster a 0.5 mA current and light an LED. The researchers claim that the new batteries could be used in distributed wireless sensors and transmitters, as well as implantable medical devices and anything else small that needs an on-board power supply
 
SpaceX Just Dropped These Amazing Retro Mars Travel Posters

1254713166669312359.jpg


Everybody wants to go to Mars these days, not least of all Elon Musk, who might very well be hoping to retire there after he turns into a cyborg. But for those of you who haven’t jumped on the bandwagon yet, SpaceX just dropped some travel posters of the Red Planet to entice you.

For a company known for pushing the technological envelope forward, the Mars travel posters are endearingly retro. Like the exoplanet tourism posters NASA dropped earlier this year, this calls back to a simpler time, when science fiction was about valiant heroes with jetpacks and ray guns fighting bug-eyed space aliens. Let’s take a peek at ‘em.

1254713166751177063.jpg


Valles Marineris is a system of canyons that run along the Martian equator. More than 2,500 miles long, 120 miles wide and 23,000 feet deep, this rift system, probably the result of ancient tectonic activity, is one of the largest in our solar system, surpassed only by a handful of rift valleys here on Earth. It’d probably be a rather fun place to explore, even bring the kids—assuming you have jetpacks and a bubble helmet like this guy does.

1254713166817730663.jpg


Only the most adventurous hikers should try to scale Olympus Mons, a shield volcano three times taller than Mount Everest. Despite being utterly massive—the entire mountain covers a surface area roughly the size of Arizona—it’s actually a rather shallow ascent, with an average slope of only 5 degrees. This poster, then, might be making a teensy exaggeration, probably to sell us on the gondola, which does look pretty great.

1254713166880392039.jpg


Mars has two funny little lopsided moons, Phobos (fear) and Deimos (panic), named after the horses that pulled the chariot of the Greek war god Ares. Thought to be captured asteroids, both moons are tidally locked, always presenting the same face toward Mars, meaning you can certainly look forward to constant vistas of the red planet if choose your real estate wisely.

Of course, Mars in reality is still a cold, airless wasteland, and none of the places depicted in this poster are likely to be good spots for human settlement. Still, you’ve got to applaud the company for trying to turn Mars into an attractive and exotic tourist destination. I almost want to pack my oxygen mask and go.
 
The First Building That Can Heal Its Own Cracks With Biological Cement

1253423780062072749.png


Three years ago, we learned that a Dutch team had developed a biological concrete that could repair its own cracks. They said it might be two or three years before it found its way into the larger world—and now, we’re getting a look at its real-world applications.

The concrete is a collaboration between two scientists named Eric Schlangen and Henk Jonkers, who are profiled today in an update on their research from CNN. The duo first made news in 2012, when they introduced their “biocement,” which uses bacteria to patch up the cracks in concrete that lead to structural degradation.

Here’s how it works: Traditional concrete aggregate is mixed with bacteria and capsules of calcium lactate. When a crack in the concrete forms, water seeps in and “activates” the bacteria, which is hard-wired to eat calcium lactate. When it does, it produces calcite—an ingredient of limestone—that accumulates to fill the space between the crack.

1253423780167320237.png


chydtucnlho3rdqzz22b.png


When io9’s Robbie Gonzalez reported on the project in 2012, it was still being tested in a lab. CNN visited Jonkers in the Netherlands to find out how development has progressed in the time since.

Jonkers and his partner have used the mixture in a real building—a lifeguard station on a lake. They’ve monitored how small cracks in the facade formed, and how the bacteria produced limestone the fill them in, almost like skin that forms a scab and then heals over completely.

1253423780393392045.png


The idea of buildings that can heal themselves has been around for decades—like the architectural nanotechnology used to rebuild Neo Tokyo that William Gibson famously imagined. It’s cool to see a technology that was being developed in a lab just a few years ago actually used in real-world buildings.
 
Spaceflight is a dangerous game, sh** happens sometimes. Happens to everyone. I hope Russia can get its space program back on track, the competition is good for our industry too, plus space exploration seems to be the one industry the US and Russia can still cooperate on.

Mexican Satellite Destroyed During Russian Rocket Explosion


Mexico’s newest communications satellite crashed into Siberia just minutes after launch early this morning. This marks the sixth catastrophic mishap of this particular configuration of a Roscomos Proton-M rocket since 2010.

jd78tvybe6ulvh841ngx.jpg


The Proton rocket with a Breeze M upper stage launched out of Baikonur Cosmodrome in Kazakhsta at 11:47 am local time (1:47:39 a.m. EDT). The first two stages went fine, but just 497 seconds into launch and at an altitude of 161 kilometers, the third stage engine booster went catastrophically wrong in a rapid unscheduled disassembly. While no details on the disaster were released by Roscosmos, the state-owned news agency Tass reports the accident was caused by a problem with the steering engine of the Proton’s third stage.

The Breeze M upper stage and the MexSat-1 payload both burned up completely in the atmosphere. Any stray debris would land near Chita, a southern Siberian city near the Chinese and Mongolian borders.

scqfc3dcuimprhhngf0p.jpg


The destroyed MexSat-1 (Centenario) satellite was part of a trio of satellites commissioned by the Mexican government. The $1 billion contract with Boeing covered the construction of three satellites to create a 3G+ mobile communications network, with another $0.6 million covering launch services. The first, Mexsat 3 (Bicentenario), launched on an Ariane 5 rocket in December 2012. The third, Morelos 3, is scheduled for launch on an Ariane 5 rocket in October 2015. The lost payload was fully covered by insurance.

This is the sixth failure of a Proton M rocket out of 43 launches since December 2010, with two other launches dropping their payloads in inadequate orbits. The previous six Proton rocket launches had gone smoothly, with the most recent mishap in May 2014. Like this most recent disaster, the problem occurred during the third stage burn. The after-action report at the time blamed the explosion on weakness in the bolts between the steering engine turbopump and the structural frame of the main engine, leading to the loss of a Russian communications satellite.

The next Proton launch — an Inmarsat communications satellite originally scheduled for June 2015 — has been delayed while the rocket failure is investigated.
 
In the Future, a Virtual Heart May Test Your Medical Device For You

1256457579630974384.jpg


Hearts are too valuable to risk—which is why the NSF announced Friday that it would be funneling millions of dollars into a new effort to develop virtual hearts for medical device development and testing.

“CyberHeart” sounds more like something we’d come across in a Terminator movie, but the new virtual heart platform, led by computer scientists at Stony Brook University, is very much tooled toward humans. CyberHearts will specifically be used to test and validate new medical devices early on during their design phase. By detecting flaws in such devices before animal and human trials begin, CyberHeart, researchers hope, will speed the development process along, while helping to prevent the rollout of products with dangerous and costly bugs.

The CyberHeart platform will essentially combine computational models of heart dynamics—for instance, it can be used to simulate electrical patterns that indicate cardiac arrhythmia—with other mathematical tools to study how the human heart interacts with medical devices. In the future, CyberHearts may also be used to optimize the heart device settings on a patient by patient basis before they are implanted.

What’s more, we now get to live in a world where virtual hearts are a thing. Crossing my fingers that we get some really cool animations out of this.
