Chinese Teen Gets World’s First 3D-Printed Vertebra Implant

 

 

 

 

” The use of 3D printers in the medical field took another step forward this week after a group of Chinese surgeons successfully implanted an artificial vertebrae replacement in a patient. The procedure is considered to be the first of its kind.”

 

 

 

 

 

 

 

”  Doctors at Beijing’s Peking University Third Hospital were able to replace the second vertebrae on a 12-year-old boy identified as Minghao. According to China Central Television, Minghao was diagnosed with cancer after injuring his neck while playing soccer. Doctors treating Minghao for the neck injury identified a malignant tumor on the boy’s spine.”

Look At What Two Years On Mars Did To The Curiosity Rover

 

 

 

Mars Rover

 

 

” NASA’s Curiosity rover just recently finished its second year exploring Mars, and the red planet’s harsh environment has taken its toll. Rocky terrain, tricky sand dunes, and exposure to Martian dust storms have left the SUV-sized robot looking a little worse for wear as it continues its march towards its eventual goal, Mount Sharp.

  Below is a before-and-after look at a variety of instruments and features on Curiosity and the wear they’ve endured during the rover’s first two years, made from images uploaded by NASA’s Jet Propulsion Laboratory. Each image is either from the MAHLI imager or the Mastcam, and is also labeled with the Sol number (sol = one Martian solar day, the mission is currently on Sol 724) during which each image was taken.”

Smartphone Add-Ons Offer Thermal Imaging

 

 

 

 

” Thermal imaging, a long-costly technology that lets soldiers see in the dark and firefighters see through smoke, is rapidly moving toward the mainstream with phone add-ons that cost hundreds of dollars rather than thousands.

  Flir Systems Inc., FLIR +0.26% one of the best-known manufacturers in the field, in July introduced a $349 iPhone accessory that allows the smartphone’s display to show glowing heat signatures of people, animals, lights and other objects. Its Flir One looks a bit like a standard protective case for a smartphone. The camera-equipped black sleeve wraps around an iPhone 5 or 5s, allowing a user to point at objects while viewing images on its display.

   Meanwhile, a group of industry veterans at a startup called Seek Thermal this fall plan to begin selling an add-on camera for smartphones for about $100 less. Rather than a sleeve, the company plans to sell a small thermal-camera module that plugs into the bottom of a smartphone. In a recent demonstration, a prototype Seek Thermal camera generated color thermal images that can be contrasted with conventional images using a split-screen feature.”

This Gun Manufacturer Just Stared Down Eric Holder And Told Him To Shove It

 

 

 

” While many anti-gun activists have responded to recent tragic shootings by demanding that law-abiding gun owners give up their Second Amendment rights, many in the industry have worked to make guns safer. One such innovator is Kodiak Arms President W.P. Gentry.

  The manufacturer spent time and money researching the potential benefits of installing software into firearms allowing them to recognize authorized users before becoming operable. Gentry noted that his company was at the forefront of perfecting such technology just months after the mass shooting at Sandy Hook Elementary School.

“ I then had the biggest development in smart-gun technology coming together at my facility in Utah,” he said, touting a product called “the Intelligun.”

  He explained that the handgun’s grip would be able to identify fingerprints and, within one second, recognize whether the holder was authorized to use the firearm or not. When Attorney General Eric Holder met with multiple gun manufacturers in April 2013, Gentry said he was invited to discuss his innovation.

 

 

“ This interested Eric Holder,” he recalled. “He wondered how we might be able to control who was or wasn’t authorized.”

 


Immediately, Gentry realized the host was proposing something antithetical to the motivation behind his research.

“ I stopped him right there,” he said. “I looked right across the table at Eric Holder – yeah, the attorney general of the United States – and told him, ‘If you try to mandate my smart-gun technology, I’ll burn it down.’”

  Gentry explained that it was clear he and Holder had opposing views regarding how to make guns safer.

 

 

“The Intelligun is designed to save lives,” he said, “not restrict freedom.”

 

 

  Holder’s interest in restricting users by utilizing the new technology is just one reason gun rights advocates say that many anti-gun activists want to see the software mandated in all firearms.”

A Swamp Cooler For Burning Man

 

Hexayurt Swamp Cooler for Burning Man

 

 

 

” For those who don’t know, Burning Man is a week-long festival in the middle of the Black Rock Desert in Nevada. The event attracts a wide range of creative people from all over the world.

  This year, [Jake] is going to bring his homemade evaporative ‘swamp cooler’ to help battle the heat. His design uses a medium-sized shipping container with two large holes cut out of it and two 200mm PC cooling fans embedded into the plastic. The fans blow air from the outside into the bin. Humidifier filters sourced from a local dump are inserted into the middle of the container. The filters acts as an absorbent material to hold melt-water being pumped in from another cooler chest above.”

Robotic Suit Gives Shipyard Workers Super Strength

 

 

RoboShipbuilder <i>(Image: Daewoo)</i>

 

 

 

” Workers building the world’s biggest ships could soon don robotic exoskeletons to lug around 100-kilogram hunks of metal as if they’re nothing.

  At a sprawling shipyard in South Korea, workers dressed in wearable robotics were hefting large hunks of metal, pipes and other objects as if they were nothing.

  It was all part of a test last year by Daewoo Shipbuilding and Marine Engineering, at their facility in Okpo-dong. The company, one of the largest shipbuilders in the world, wants to take production to the next level by outfitting staff with robot exoskeletons that give them superhuman strength.

  Gilwhoan Chu, the lead engineer for the firm’s research and development arm, says the pilot showed that the exoskeleton does help workers perform their tasks. His team is working to improve the prototypes so that they can go into regular use in the shipyard, where robots already run a large portion of a hugely complex assembly system.

  The exoskeleton fits anyone between 160 and 185 centimetres tall. Workers do not feel the weight of its 28-kilogram frame of carbon, aluminium alloy and steel, as the suit supports itself and is engineered to follow the wearer’s movements. With a 3-hour battery life, the exoskeleton allows users to walk at a normal pace and, in its prototype form, it can lift objects with a mass of up to 30 kilograms.”

Simple Blood Test Can Now Detect Cancer

 

 

 

 

 

 

” In a first, British researchers have devised a simple blood test that can be used to diagnose whether people have cancer or not.

  Early results have shown the new test gives a high degree of accuracy in diagnosing cancer and pre-cancerous conditions from the blood of patients with melanoma, colon cancer and lung cancer.

  The test will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures, researchers said.

” We found that people with cancer have DNA which is more easily damaged by ultraviolet light than other people, so the test shows the sensitivity to damage of all the DNA — the genome — in a cell,” explained professor Diana Anderson from the University of Bradford’s School of Life Sciences.”

Why The Salvo 12 Is The Most Important Suppressor Ever Made (VIDEO)

 

 

 

 

 

” Things have gotten pretty exciting lately with the announcement of the Salvo 12. Everyone, not just SilencerCo, is pretty wired about the concept of a suppressed shotgun. It’s been done before, but only by boutiques and never by anyone with the clout and standing that SilencerCo has in this industry.

  SilencerCo’s rise to being number one seller of suppressors has been nothing short of phenomenal.

  Founded in 2008, the company started out as a two-man operation and is now an industry leader. They’ve done by being innovative and hands-on, producing a better, longer-lasting product and focusing on marketing.

“ I jumped on a plane and flew to all 39 states where silencers are legal to meet with dealers,” said Joshua Walden, one of SilencerCo’s founders, to Inc. magazine. “We ended up taking so many preorders that we sold out our first batch of 200 silencers before they had even been made. The first year, we sold 750 Sparrows. Soon after, we developed and released our next product, the Osprey, a silencer for handguns.”

  A big hurdle for the company has been just getting the idea out there that suppressors are legal, helpful and attainable. They’re not taboo, they make shooting easier and safer. They’re aware that silencers have been villainized and distorted over decades of bad press, when in reality they’re just another tool in the shooting kit.

  Which is why the Salvo 12 is the most important suppressor ever made.”

Integrally Suppressed 10/22

 

 

 

 

 

 

” Great Lakes Tactical makes integrally suppressed 10/22 rifles that are a beautiful thing to (not) hear.

  As I mentioned earlier in the week, I had the chance to do some shooting with the guys at Great Lakes Tactical in Ohio.  In addition to the full auto Glock, they brought along one of their integrally suppressed 10/22 rifles.  This was a nice piece of hardware.

  The 10/22 I shot used a Green Mountain barrel with a sleeve over it.  The barrel was cut and when combined with the sleeve acted as a very effective sound suppressor.  The sleeve comes off easily for cleaning, and gives the rifle a nice bull barrel look.”

Making Men Equal: The Legend Of Samuel Colt’s 200th Birthday

 

 

 

 

 

” It was in the winter of 1831 that Sam Colt saw a revolving pistol for the first time. This occasion was so important that he lied about it in later years. The gun shop he visited in Calcutta had a few examples of the Collier revolving flintlock pistol. Studying them gave Sam ideas for improving the revolver. The main fault of the Collier, Sam thought, was the method by which the cylinder was rotated. After each shot was fired, the shooter had to set the cylinder into a firing position by hand, always making sure that a loaded chamber was in line with the barrel. This had to be done each time the pistol was fired. Then, too, the Collier had too many parts; more than 40 separate pieces went into the lock, not including the lockplate, attaching screws, stock, cylinder and other essentials. His invention would cut down the number of parts, but, more important, he would devise a method of turning the cylinder automatically, not by hand.”

 

 

 

 

 

 

” With financial aid from his father, Christopher, Sam sought the services of Anson Chase, a gunsmith of Hartford, Connecticut. Chase agreed to produce the working models Colt needed and set himself to the task. He made a pistol, which closely followed Colt’s wooden pattern, then turned his efforts toward producing a revolving rifle. On December 30, 1831, using money he received as a Christmas gift, Colt paid Chase $15 on the account, but where or when he would get the balance lay in doubt.

  When he left his home in Ware, Massachusetts, the youth Samuel Colt was no more. In his place stood Dr. Coult, the celebrated lecturer and scientist of New York, London and Calcutta. The deception was magnificent and enabled Sam to collect fees for lecturing on natural philosophy and chemistry. After each lecture, he would delight his audience with a demonstration of laughing gas. Using a willing participant, Sam administered the gas, which induced a form of harmless intoxication.”

 

 

 

 

” When Sam arrived in Hartford in December 1833, Chase showed him another crude specimen fashioned from the original model. They were eager to test it, and the revolver was promptly loaded, placed in a vise and fired. Much to the dismay of the two men, the revolver burst apart. It was a disheartening thing to have happen, but it was the first hint of a trouble that would plague Colt for several years — re-flash. A front plate, which held the loose bullets from falling out, trapped the lateral flash at the breech end of the barrel. This pushed the hot particles of gunpowder into the adjoining chambers, setting off the other charges. When all the charges fired at once, they literally tore the barrel right off the gun. Sam was dejected over his gun’s failure, but, being a good showman, and needing more money for future experiments, he headed to Baltimore to continue his lectures.”

Costa Concordia Refloating Complete, Heading Soon To Scrap Heap

” The wreck of the luxury liner Costa Concordia was re-floated on Monday and will soon be towed away and broken up for scrap, more than two years after it capsized off the Italian coast, killing 32 people.

  The 290-meter Costa Concordia ran aground on rocks near the Tuscan holiday island of Giglio on Jan. 13, 2012. The rusting hulk of the once-gleaming-white ship had been resting on a temporary platform since being righted a year ago.

  In what has become one of the largest salvage operations in history, air was pumped into 30 large metal boxes, or sponsons, attached around the hull of the 114,500-ton ship. The air forced out the water in the sponsons, lifting the vessel off the underwater platform.”

This Bullet Can Change Direction Mid-Air To Track Down Its Target

 

 

 

” The future of war is a laser-guided bullet that can change direction and hit targets at a distance of over one mile away.

  DARPA, the research arm of the Pentagon, has developed the EXACTO system to put a four-inch-long bullet with an optical laser sensor and an eight-bit central processing unit that can compute an algorithm to command electromagnetic steering to give the bullet its deadly precision.

  Unlike most rifle bullets, EXACTO has no spin. Instead, it travels like an electronic dart with fins that can guide it in mid-air.

  A sniper team can control the bullet after firing to ensure accuracy while compensating for weather, wind, target movement, and a range of other factors.”

3D Printed Ruger Pistol Demonstration By Buck O’ Fama

 

 

 

 

 

 

” An experimenter under the nom de plume of Buck O’ Fama has printed the receiver for the popular Ruger Charger pistol, and assembled a working pistol with it.   The video shows the test fire of the gun, which appears to work well.    It has always been legal to make your own firearms in the United States, if they are not prohibited weapons.   Pistols such as the Ruger have been ruled to be protected under the Second Amendment to the Constitution.   At the end of the video, the experimenter notes: “If you take my gun, I will just print another one
   The video was posted on July 4th, Independence Day, from somewhere in the State of Nevada.   It is interesting that in spite of the fact that the poster did nothing illegal, they felt compelled to disguise their voice.”
     The truly disturbing thing about this video is the poll that was included on LiveLeak asking if people should have the right to create their own firearm with 3D printing . I guess that LiveLeak is no different than a lot of the social media sites in that there is a ‘leftist” tilt to the users , anyway here is a screenshot of the poll (now closed) results .

Watch The World’s Tallest Water Slide Test Its First Human Riders

 

 

 

 

” The Verrückt, the world’s tallest water slide, has finally started testing with real, live humans. And the first drop in this POV footage is absolutely terrifying.

  Located in Kansas City, Schlitterbahn water park has been pushing back the big unveiling of their monster slide (The Verrückt) again and again. But this video with slide’s engineers taking the first human ride gives us hope that it may just be safe enough for the public soon.” 

” Here are the facts. The Verrückt is 168 feet and 7 inches tall. The Statue of Liberty (from toes to the tip of the flame) is only 151 feet. It’s also taller than Niagara Falls. You have to climb up 264 steps to get to the top of the 17-story slide. It’s expected to hit speeds of up to 65 miles-per-hour. And when you ride you must be velcro strapped into a very large raft (which is good because you would have no butt if you did this bare bottomed). ‘

Sand-Based Lithium Ion Batteries That Outperform Standard By Three Times

 

 

 

 

 

” Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times. The key material: sand. Yes, sand.

” This is the holy grail – a low cost, non-toxic, environmentally friendly way to produce high performance  anodes,” said Zachary Favors, a graduate student working with Cengiz and Mihri Ozkan, both engineering professors at UC Riverside.

  The idea came to Favors six months ago. He was relaxing on the beach after surfing in San Clemente, Calif. when he picked up some sand, took a close look at it and saw it was made up primarily of quartz, or . “

Inventor Of Kevlar, Tougher-Than-Steel Fiber In Bulletproof Vests, Dies

 

 

 

 

 

 

” Police Lt. David Spicer took four .45-caliber slugs to the chest and arms at point-blank range and lived to tell about it. Like thousands of other police officers and soldiers shot in the line of duty, he owes his life to a woman in Delaware by the name of Stephanie Kwolek.

  Kwolek, who died Wednesday at 90, was a DuPont chemist who in 1965 invented Kevlar, the lightweight, stronger-than-steel fiber used in bulletproof vests and other body armor around the world.

  A pioneer as a woman in a mostly male field, Kwolek made the breakthrough while working on specialty fibers at a DuPont laboratory in Wilmington, Delaware. At the time, DuPont was looking for strong, lightweight fibers that could replace steel in automobile tires and improve fuel economy. “

” x.pose is a wearable data-driven sculpture that exposes a person’s skin as a real-time reflection of the data that the wearer is producing. In the physical realm we can deliberately control which portions our bodies are exposed to the world by covering it with clothing. In the digital realm, we have much less control of what personal aspects we share with the services that connect us. In the digital realm we are naked and vulnerable. “

Toyota To Start Producing Fuel Cell Vehicles In December

 

 

 

 

 

 

” Toyota’s hydrogen fuel cell vehicle will go into production ahead of schedule, with production planned for mid-December 2014.

  Sales will also begin “by the end of the year” reports Japan Times (via Autoblog), ahead of Toyota’s original on-sale date some time in 2015.

  No reason has been given for bringing the car forward, but it’s safe to assume Toyota’s development and testing is going smoothly so far – unusual in the alternative fuel vehicle market.

  Toyota first revealed its fuel-cell vehicle as the FCV-R concept in 2012. The concept was subsequently updated in 2013, and the car was revealed in testing camouflage earlier on this year.”
