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. “

This Top Turns See-Through If You Leave Personal Data Exposed

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

” A Brooklyn-based designer has created a 3D-printed sculptural boob tube to spark social commentary on the state of privacy in a data-driven world — by making the top gradually more sheer.”

 

 

 

 

 

 

” X.pose’s striking black webbed rubber structure was engineered using a Stratasys printer, moulded to the body to ensure comfort and very much inspired by creator Xuedi Chen’s previous work, Invasive Growth (moss-grown jewellery based on the parasitic cordyceps fungus). But underneath, its layers tell another story about our lack of control and veritable vulnerability when it comes to who uses our data, what for and how much they take.”

 

 

The artist describes her creation thusly …

 

 

” 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.”

SpaceX Shows Off Dragon V2, Its Brand New Manned Space Capsule

 

 

 

 

 

 

” At an evening event in the SpaceX Headquarters on Thursday night, CEO and founder Elon Musk revealed the Dragon V2 space capsule, a next-generation version of SpaceX’s current Dragon capsule that will be able to ferry up to seven crew members and cargo to the International Space Station (ISS) and eventually to other destinations. The capsule is reusable, and will be able to make a controlled landing “with the precision of a helicopter” upon re-entry. 

  The capsule, which has been in development for several years with help from NASA, will be a part of a new generation of commercial space vehicles since the US shuttered its own shuttle program in 2011. Currently, NASA pays Russia around $71 million a head to taxi astronauts to and from the ISS on Soyuz vehicles.

  Tonight, Musk told the press that his company foresees being able to send astronauts to the ISS and back for around $20 million per seat.

  Musk added that depending on how many flights SpaceX is able to launch, that cost-per-head number could come down significantly to where it could “potentially get into the single-digit-million figure.”

  NASA has publicly stated that it wants a commercial space vehicle to be ready for prime time by 2017; Musk told Ars tonight that NASA is being characteristically cautious: “from a SpaceX standpoint we expect to be ready to transport crew by 2016,” he said. “We feel fairly confident that we’ll be ready in two years.” When the Dragon V2 does launch, it’ll launch from the historic pad 39A at the Kennedy Space Center, which SpaceX recently signed a 20-year lease for.”

Star Trek-Style ‘Tractor Beam’ Created At University

 

 

 

” Scientists at Dundee University have created a working “tractor beam“.

  Normally the stuff of science fiction in Star Trek or Star Wars, physicists at the university used an ultrasound array to exert force on an object and pull it towards the energy source.

  They say it is the first time such a beam has been used to move anything bigger than microscopic targets.

  The technology could be put to use in medicine, helping to develop ultrasound-based clinical techniques.

  Dundee researchers worked alongside colleagues in Southampton and Illinois on the project, the results of which have been published in the scientific journal Physical Review Letters.

  In another sci-fi inspired project, the same team from the university’s Institute for Medical Science and Technology (Imsat) created a Doctor Who-style “sonic screwdriver”, also using ultrasound.”

Unmasking The Columbia River’s Mysterious Stealth Boats

 

 

 

 

” For about a decade there have been sightings of some very peculiar high-speed watercraft patrolling up and down the Columbia River between Portland and Vancouver. It just so happens that these phantom vessels are some of the US Navy SEALs newest toys.”

 

 

 

 

” The origin of these boats remains somewhat shadowy, but it would seem that they evolved from a concept initiated by the Israeli Special Operations community in the late 1980’s. Patents filed in the 1990s show the design would become “the Alligator,” a semi-submersible, high-speed special forces delivery, extraction and reconnaissance craft that features a very low radar cross-section. All known accounts state that the Alligator was first launched in the mid 1990s and was said to have been tested briefly by the US Special Operations community before being delivered to Israel. The number of alligators built remains a mystery.”

 

 

 

 

” The already low-slung Alligator has the ability to lower its draft to the point where the cabin windows sit right above the waterline via flooring ballast tanks located on each side and below the boat’s main cabin. This results in the boat not only being very hard to spot on radar but it is also challenging to spot visually. The streamlined hull and low drag design, along with some powerful water-jets, allow it to move at high speed, especially when its ballast tanks are empty.”

 

 

 

 

” Although I have had some trouble getting a confirmation on it, it seems that Oregon Iron Works, a locally well known metal fabrication firm, has been involved with building the Alligator since its inception and continues as the prime contractor for constructing not only the Alligator Class but also its follow-on Sealion and Sealion II Class.”

 

 

 

   This picture was taken by yours truly in Newport RI somewhere around 2007 . It is not an “Alligator” or a “SeaLion” but it is a stealth insertion craft nonetheless . There were four of them that were making there way from Norfolk Va up to Portsmouth NH on a shakedown cruise all manned by un-uniformed sailors .

 

 

100_0833

 

 

 

    Here’s another shot of these stealthy craft that had two huge conventionally (gas) powered motors yet were virtually silent at any lower speed . As I recall they were designed with seating for a three man crew , helmsman , navigator and co-pilot and had jump-seats in the rear to transport up to six spec-ops warriors .

 

 

100_0842

 

 

    I have more pictures of these amazing craft somewhere and will post more if I can locate them . The boats and their crews spent the night in Newport at the same marina we were staying at and they left early the next morning and you could not even hear them leaving . Amazing technology . The crew , who were understandably tight-lipped did reveal that they had left Norfolk the day before and thus revealed something of the speed of these craft .

Entrepreneur Invents Holiday Beach Locker That Screws Into The Sand

 

 

Hidden treasure: Laying on the towel over the beach vault means you can rest-assured your valuables will be safe

 

 

” It’s the age-old problem of deciding where to store your valuables at the beach while enjoying a day-time snooze or a dip in the sea.

  However, an entrepreneur has invented a unique locker that can screw into the sand and hold personal items such as purses, mobile phones, small tablets and money.”

 

 

BEACH VAULT

 

 

” Marcal DaCunha’s Beach Vault, which is expected to retail for £18, is closed by a special waterproof lid to stop any liquid seeping inside, and then covered by a towel and pillowcase.”

 

 

” DaCunha, a church pastor from New Jersey in the US, said: ‘The whole thing started when my wife, Krystal, and I were travelling back from the beach.

‘ She said “What if we had a container you could put underneath your towel that could hide all of your stuff?”
‘The idea was that if you were lying on the towel and you fell asleep you wouldn’t have to worry about watching your stuff or trying to keep hold of it while closing your eyes.

‘ We spoke about it and spent a while making prototypes and coming up with ideas and we have now worked with engineers to come up with the Beach Vault.”
