Firearm Safety: Colorado Student Invents Smart Gun

smartgun1In the course of considering the rash of gun violence and mass shootings that have swept the US in recent years, a great deal of attention has become focused on “smart guns”. Incorporating the latest in biometrics, fingerprinting and wireless connectivity, these weapons are designed to only be usable by their rightful (and presumably, legal) owners. One such concept comes from Colorado – which has a history of gun violence – and from a high school student, no less.

His name is Kai Kloepfer, a 17 year-old a high school student from Boulder who just won the $50,000 Smart Tech for Firearms Challenge for his smart gun prototype. Inspired by the recent school shooting in Connecticut and undeterred by the lack of legislative change in Washington DC, the Smart Tech Foundation believes that ingenuity, technology and the invisible hand of the free market will persevere where the federal government has failed.

smartgun_markAngel investor and gun reform advocate Ron Conway became the main backer of the $1 million Smart Tech prize to spur gun safety solutions earlier this year. As he said to the SF Examiner in January of this year, he hopes people will “use innovation to bring about gun safety. Let’s not rely on Washington”. According to the Smart Tech Foundation, a total of 15 innovators will receive a part of that million dollar prize.

Kloepfer is the first to get the award. His gun design works by creating a user ID and locking in the fingerprint of each user allowed to use the gun. The gun will only unlock with the unique fingerprint of those who have already permission to access the weapon. According to Kloepfer, all user data is kept on the gun and nothing is uploaded anywhere else, so it would be very difficult to hack. This potentially makes it ideal for military use as well.

smartgunKloepfer came up with the idea two years ago when he needed something for his high school science project. The Aurora, Colorado shooting had recently happened just an hour’s drive on his home, and was on everyone’s mind at the time. Kloepfer’s parents helped him in monetary increments to get the parts needed for each improvement. It would eventually cost $3000 for the whole thing to come together, maturing from phase to phase with each science fair.

As he explains the inspiration and development process:

The idea came to me right as I was falling asleep. It was kinda in the back of my mind because of the shooting. I scribbled it down before I went to bed and fell asleep and then in the morning I began my research… At first it was just a concept on paper. Right now it’s a prototype on a plastic model. Its not entirely there but it works.

kai-kloepfer-smart-tech-13Some of the $50,000 has already been used to purchase a 3D printer to create new parts for his prototype. Kloepfer, who will graduate from Fairview High School this year, plans to use the rest of it toward the integration of a fingerprint scanner. Ultimately, he hopes his and other designs like it will make a dent in the problem of gun violence and help to reduce the needless deaths caused by it:

Every 30 minutes in the U.S. a kid dies from a gun. I want my gun to help reduce accidental deaths and injuries, and to prevent tragedies.

His intentions are certainly well-placed. According to the Center for Injury and Research Policy, 1500 kids die from a gun and many more are seriously injured every year. And according to the Smart Tech Challenges Foundations own website, 2 million children live in a home with a firearm that is both loaded and unlocked. So beyond gun violence, gun safety advocates are sure to see the value in developing the technology.

smartgun_lockKloepfer also spoke about his biometric smart gun tech this past week at the TEDx Mile High: CONVERGENCE in Denver, Colorado. Stay tuned, for I plan to post the video of his talk as soon it becomes available! And in the meantime, be sure to check out the Smart Tech Challenge Foundation’s website for more information on the winners of the challenge.

Hidden Archaeology of Stonehenge Revealed

Stonehenge,_Condado_de_Wiltshire,_Inglaterra,_2014-08-12,_DD_09Ever since it was first uncovered, Stonehenge has remained a mystery for archaeologists, historians and folklorists alike. First constructed in the Neolithic Era, the purpose and function of these standing stones – set within a dense complex of burial mounds and monuments – are still a matter of speculation and debate. But now, researchers have revealed hundreds of previously unknown features which might shed light on this mysterious site.

As part of the Stonehenge Hidden Landscapes Project, the researchers used a comprehensive array of remote sensing technology and non-invasive geophysical survey equipment to scan deep beneath the ground. These finds include images of dwellings that date from the Iron and Bronze Ages, as well as details of buried Roman settlements that have never before been seen.

Stonehenge_renderIncluded in the findings are many dozens of burial mounds, including a long barrow entombment structure that predate the construction of Stonehenge itself. Revealed in great detail by the team’s geophysical instruments, the structure appears to have been a very large timber building. The researchers believe this may have been a preparation room where the dead were defleshed before burial, a popular practice amongst tribes inhabiting the area at the time.

Later structures that were built around the well-known circular form were also revealed by this new research, with seventeen previously unidentified ritual monuments being discovered and mapped. These types of results show how new applications of geophysical technology can add to the understanding of archaeological sites; in this case, it is shedding light on the hidden landscape of a site that is 11,000 years in the making.

stonehenge-2As British project leader Professor Vincent Gaffney of the University of Birmingham explained:

Despite Stonehenge being the most iconic of all prehistoric monuments and occupying one of the richest archaeological landscapes in the world, much of this landscape in effect remains terra incognita. This project has revealed that the area around Stonehenge is teeming with previously unseen archaeology and that the application of new technology can transform how archaeologists and the wider public understand one of the best-studied landscapes on Earth.

The techniques included magnetic gradiometer systems, ground and airborne laser-scanning, and ground-based radar, all of which were mapped to GPS systems to provide total GIS (Geographic Information System) coverage. The research also revealed that the Durrington Walls “super henge,” located just two miles (3.2 km) north-west of Stonehenge, had once been surrounded by a circle of massive posts or standing stones.

stonehenge-4Believed to have consisted of up to 60 posts or stones some 12 ft (3 m) tall, the geophysical mapping suggests that some of these may still even be intact somewhere under the enormous earthen banks surrounding the monument. Viewable only through the advanced technology used in the project, this discovery and mapping work has already added yet another dimension of knowledge to this vast and mysterious edifice. According to Professor Gaffney:

New monuments have been revealed, as well as new types of monument that have previously never been seen by archaeologists. All of this information has been placed within a single digital map, which will guide how Stonehenge and its landscape are studied in the future.

What’s more, the project uncovered large burial tombs containing more gold and jewelry than graves anywhere else in Britain, indicating that the area was a cemetery for the rich and powerful. Some of the treasures found by archaeologists were made with materials and techniques originating from the European continent. All of the findings are explored in “Stonehenge Uncovered”, the season premiere of CBC’s The Nature of Things that will be airing on Oct. 9.

stonehenge-0British and U.S. versions of the film will air on BBC and the Smithsonian Channel respectively. Terence McKeown, president of Lightship Entertainment and the film’s Canadian executive producer, said that before working on the film, he had the impression that Stonehenge was always an isolated monument in a landscape populated by little more than a “handful of monks.”

The Hidden Landscapes Project – and the new film – reveal a very different picture. As McKeown put it:

What Stonehenge appears to have been was the spiritual centre of a sophisticated culture. The population around Stonehenge clearly included accomplished engineers, surgeons, artisans, and there’s evidence they had close ties to Europe that advanced their skills.

News from Mars: ExoLance Project to Hunt for Life

exolance-2The search for life on Mars has been ongoing, and predates the deployment of the Curiosity rover by many years. However, it is becoming increasingly clear that if signs of life are to be truly found, they won’t turn up by scratching around on the surface. Beyond Curiosity’s own slated inspection of Mount Sharp (where it just arrived!) NASA has some long-range plans that reach deeper.

Outside of NASA’s InSight Lander, which is set to launch in the spring of 2016, there’s Explore Mars’ plan to look for signs of life beneath the surface. A private organization made up technologists and former NASA engineers, their plan is to drop supersonic lances onto the planet that will penetrate deep into the Martian soil to seek out protected, potentially wet strata where life might still exist.

exolanceKnown as ExoLance, the project is designed to take up where the Viking missions of the late 1970s left off. In these first successful Mars landers, there was an experiment on board that looked for signs of life in the Martian soil. This consisted of the Viking lander scooping up soil, depositing it inside the automatic laboratory in the lander, squirted a nutrient solution into the sample, and analyzing the gases given off that might indicate the presence of life.

The Viking experiment did give off gases that seemed like they were due to living organisms, but it later discovered that these were due to chemical reactions due to the extremely dry conditions and constant bombardment of UV radiation. Because of this, NASA has preferred to focus more on geology to gain a better understanding of the Martian environment rather than looking for life directly.

exolance-3But Explore Mars wants to go back to the direct approach by combining an experiment similar to the Viking lab with a delivery system based on the US Air Force’s bunker-buster weapons. They also hope to incorporate technology developed for the Curiosity rover, which includes reusing the aeroshell that protected the Curiosity rover as it made its descent to the Martian surface in 2012.

When the shell reaches Mars, it will open up to reveal a delivery vehicle similar to the Skycrane that delivered Curiosity to the surface by hovering under rocket power while it winched the lander down. In the case of the ExoLance, the vehicle – which is appropriately called a Quiver – will hover in place. But instead of lowering a rover, it will fire multiple penetrator probes at the ground.

exolance-1These perpetrators, called Arrows, are small, lightweight versions of the bunker-buster bombs that were developed by the US forces during the 1991 Gulf War. However, instead of exploding, the Arrows will strike the surface at supersonic speeds to bore deep into the ground and (similar to NASA’s Deep Space 2 probe) split in two to deploy a cache of scientific equipment packed into the nose.

While the tail section remains on the surface to act as a transmitter back to Earth, the nose bores about 5 m (16 ft) into the surface to find protected layers that may contain water, but which are shielded against the deadly surface radiation. Once in position, the Arrow activates its experiment, which is designed to not only detect signs of living organisms, but also to determine if the life signs are those of microbes similar to those found on Earth, or have a completely different origin.

exolance-4The mission is the subject of an Indiegogo crowdfunding campaign aimed at raising US$250,000. The group says that within a year of raising its Indiegogo funding, it would develop and build Arrow prototypes and test them in the Mojave Desert by dropping them from aircraft. The idea is not only to see if the experiments can survive the impact, but also to make sure that the penetrators don’t dig in too deep or too shallow.

In addition, the group expects the design to change as they deals with problems, such as the volume of the cylinder, batteries, deploying the tether linking the two segments, and making sure the components can withstand the impact. In the second year, the group plans to enact Phase II, which would concentrate on developing the microbial experiments. If this is successful, they plan to approach NASA or commercial companies to arrange delivering ExoLance to Mars.

The crowdfunding campaign will run until September 29th, and has raised a total of $15,680 of their projected goal. To check out this campaign, or to contribute, click here. And be sure to check out Explore Mars’ promotional video below:

The Future of Medicine: The “Human Body-on-a-Chip”

bodyonachip One of the aims of modern medicine is perfecting the way we tests treatments and drugs, so that the lengthy guess-work and clinical trials can be shortened or even cut out of the equation. While this would not only ensure the speedier delivery of drugs to market, it would also eliminate the need for animal testing, something which has become increasingly common and controversial in recent years.

Over the last century, animal testing has expanded from biomedical research to included things like drug, chemical, and cosmetic testing. One 2008 study conducted by The Guardian estimated that 115 million animals are used a year for scientific research alone. It is therefore no surprise that opposition is growing, and that researchers, regulators and even military developers are looking for more accurate, efficient, and cruelty-free alternatives.

bodyonachip1Enter the National Insitute of Health in Besthesda, Maryland; where researchers have teamed up with the FDA and even DARPA to produce a major alternative. Known as the “Human Body-on-a Chip”, this device is similar to other “Organs-on-a-chip” in that it is basically a small, flexible pieces of plastic with hollow micro-fluidic channels lined with human cells that can mimic human systems far more effectively than simple petri dish cell cultures.

Dan Tagle, the associate director of the NIH’s National Center for Advancing Translational Sciences, explained the benefits of this technology as follows:

If our goal is to create better drugs, in a way that is much more efficient, time and cost-wise, I think it’s almost inevitable that we will have to either minimize or do away with animal testing.

https://i0.wp.com/images.medicaldaily.com/sites/medicaldaily.com/files/styles/large/public/2014/03/18/new-technology-may-obviate-need-animal-testing.jpgWhat’s more, chips like this one could do away with animal testing entirely, which is not only good news for animals and activists, but drug companies themselves. As it stands, pharmaceutical companies have hit a wall in developing new drugs, with roughly 90% failing in human clinical trials based on safety and effectiveness. One reason for this high rate of failure is that drugs that first seem promising in rodents often don’t have the same response in people.

In fact, so-called “animal models” are only typically 30% to 60% predictive of human responses, and there are potentially life-saving drug therapies that never make it to human clinical trials because they’re toxic to mice. In these cases, there’s no way to measure the lost opportunity when animals predict the wrong response. And all told, it takes an average of 14 years and often billions of dollars to actually deliver a new drug to the market.

bodyonachip2According to Geraldine Hamilton, a senior staff scientist at Harvard University’s Wyss Institute for Biologically Inspired Engineering, it all began five years ago with the “lung-on-a-chip”:

We’ve also got the lung, gut, liver and kidney. We’re working on skin. The goal is really to do the whole human body, and then we can fluidically link multiple chips to capture interactions between different organs and eventually recreate a body on a chip.

This has led to further developments in the technology, and Hamilton is now launching a new startup company to bring it to the commercial market. Emulate, the new startup that will license Wyss’s technology, isn’t looking to literally create a human body but rather to represent its “essential functions” and develop a platform that’s easy for all scientists and doctors to use, says Hamilton, who will become Emulate’s president and chief scientific officer.

lung-on-a-chip-5Borrowing microfabrication techniques from the semiconductor industry, each organ-on-a-chip is built with small features – such as channels, vessels, and flexible membranes – designed to recreate the flow and forces that cells experience inside a human body. All that’s needed are different chips with different culture of human cells; then researchers can performed tests to see how drugs work in one region of the body before being metabolized by the liver.

This might one day help the military to test treatments for biological or chemical weapons, a process that is unethical (and illegal) with humans, and cruel and often inaccurate with animals. Hospitals may also be able to use a patient’s own stem cells to develop and test “personalized” treatments for their disease, and drug companies could more quickly screen promising new drugs to see if they are effective and what (if any) side effects they have on the body’s organs.

It’s a process that promises speedier tests, quicker delivery, a more cost-effective medical system, and the elimination of cruel and often inaccurate animal testing. Can you say win-win-win?

The Future of Naval Warfare: Supersonic Submarines

Chinese_subsResearchers in China are reporting that they’ve taken a big step towards creating a truly revolutionary submarine. For years, the nation has been dedicated to the expansion of the People’s Liberation Army Navy (PLAN) Submarine Force. That latest announcement in this plan is the intended development of supersonic submarines. And if feasible, it could a sub to travel from Shanghai to San Francisco – a distance of about 9650 km (6,000 miles) – in just 100 minutes.

The research behind this proposed development comes from the Harbin Institute of Technology’s Complex Flow and Heat Transfer Lab, where researchers are applying a concept known as supercavitation. Originally conceived by the Soviets in the ’60s to create high-speed torpedoes, the Harbin researchers are looking to take things to the next level by applying it to a much larger sea-faring vessel.

https://i0.wp.com/www.extremetech.com/wp-content/uploads/2014/08/supercavitation-diagram.jpgAs is commonly known, objects moving through water have a harder time than those moving through air. While automobiles are only able to travel so fast before succumbing to wind resistance (aka. drag), surface ships and submarines must content with fluid-dynamics, which are much more tricky. Compared to air, water is far more dense and viscous, which means more energy is required to get up to a certain speed.

Even the most modern and advanced nuclear submarine cannot travel much faster than 40 knots (74 kph/46 mph), and the same applies to torpedoes. Higher speeds are possible, but would require so much power to make it impractical. That’s where supercavitation comes into play, a technique devised with the explicit purpose of creating high-speed torpedoes during the Cold War.

Shkval_headThis technique gets around the drag of water by creating a bubble of gas for the object to travel through. In the hands of the Soviet’s, the research resulted in the Shkval torpedo, which uses a special nose cone to create the supercavitation envelope that allows it to travel through the water at speeds of up to 200 knots (370 kph/230 mph) – much, much faster than the standard torpedoes fielded by the US.

The only other countries with supercavitational weapons are Iran – which most likely reverse-engineered the Russian Shkval – and Germany, the creators of the Superkavitierender Unterwasserlaufkörper (“supercavitating underwater running body”). The US is researching its own supercavitational torpedo, but there’s very little public information available. Meanwhile, China is not only looking to create supercavitating torpedoes, but an underwater vessel.

supercavitational-torpedo-techUnlike previous designs, which had to be launched at speeds of 95 km (60 mph) to create a supercavitation bubble, the method described by the Harbin researchers uses a “special liquid membrane” to reduce friction at low speeds. This liquid is showered over the object to replenish the membrane as it’s worn off by the passage of water, and once the object gets up to speed, it would theoretically use the same nose-cone technique to achieve supercavitation.

In theory, supercavitation could allow for speeds up to the speed of sound — which underwater is 5343 kph (3,320 mph) – which would allow a sub to go from Shanghai to San Francisco in well under two hours. For any nation with a nuclear arsenal – i.e. China, Russia, France, the UK, the US – the ability to deploy nuclear missile subs speedily around the world is certainly desirable.

https://i0.wp.com/grupocaos2007.brinkster.net/supercav2/BancoPruebMini.JPGBut of course, there are some challenges posed by the concept and any ship that is equipped to run on it. For one, it is very difficult to steer a supercavitating vessel and conventional methods (like rudders) don’t work without water contact. Second, developing an underwater engine that’s capable of high velocity over long distances is very difficult. Jet engines do not work underwater and generally, rockets only have enough fuel to burn for a few minutes.

Nuclear power might be a possibility as far as supersonic submarines go, but that’s strictly academic at this point. Li Fengchen, a professor at the Harbin Institute, says their technology isn’t limited to military use. While supersonic submarines and torpedoes are at top of the list, the same technology could also boost civilian transport, or even boost the speed of swimmers. As Li put it:

If a swimsuit can create and hold many tiny bubbles in water, it can significantly reduce the water drag; swimming in water could be as effortless as flying in the sky.

https://storiesbywilliams.com/wp-content/uploads/2014/09/e1095-chinese_submarine.jpgAs always with such advanced (and potentially weaponized) technology, it’s hard to say how far away it is from real-world application. Given that this is primarily a military research project within China, one can expect that it will remain shrouded in secrecy until it is ready. And if civilian researchers are making good progress, then it’s a fairly safe bet that the military is even further along.

While the future of transit is already exciting – what with hyperloops, aerospace travel, robotaxis and robot cars – the idea that people could travel under the waves as fast as on they could on the Concorde is pretty cool! At the same time, the idea that subs equipped with nuclear missiles could reach our shores within two hours is pretty scary. But futuristic military technology has never been known to inspire warm and fuzzy feelings, has it?

Finalists Selected for Qualcomm Tricorder XPrize

Tricorder X_prizeFirst announced in 2012, the Qualcomm Tricorder XPRIZE has sought to bring together the best and brightest minds in the field together to make science fiction science fact. In short, they sought to create a handheld device that could would mimic some of the key functions of the iconic Star Trek tricorder, allowing consumers access to reliable, easy to use diagnostic equipment any time, anywhere, with near instantaneous results.

And now, the list of potential candidates has been whittled down to ten finalists. And while they might be able to live up to the fictitious original, the devices being developed are quite innovative and could represent a significant technological advancement in the diagnostic domain. Qualcomm is offering a US$10 million prize purse in the hope of stimulating the research and development of precision diagnostic equipment.

medical_tricorderIn order to qualify for the prize, the successful scanner must comply with an ambitious set of parameters. First, the device must be able to reliably capture an individual’s heart rate, respiratory rate, blood pressure, and oxygen saturation in an easy to use and completely non-invasive fashion. It must also diagnose 13 core diseases – including pneumonia, tuberculosis and diabetes – along with three additional health conditions to be chosen by each team.

Each device varies widely in terms of appearance and composition, but that’s hardly surprising. The only limitations placed on the teams in terms of construction is that the entire apparatus must have a mass of less than 2.3kg (5 lb). Due to the wide range of tests needed to be carried out by the tricorder in order to capture the necessary health metrics, it is highly unlikely that any of the scanners will take the form of a single device.

qualcommtricorderchallenge-3The shortlisted entries include Scanadu (pictured above), a company which is currently developing an entire portfolio of handheld medical devices. The circular sensor is programmed to measure blood pressure, temperature, ECG, oximetry, heart rate, and the breathing rate of a patient or subject – all from a simple, ten second scan. Then there’s Aezon, an American-based team comprised of student engineers from Johns Hopkins University, Maryland.

The Aezon device is made up of a wearable Vitals Monitoring Unit – designed to capture oxygen saturation, blood pressure, respiration rate and ECG metrics – and The Lab Box, a small portable device that makes use of microfluidic chip technology in order to diagnose diseases ranging from streptococcal pharyngitis to a urinary tract infection by analyzing biological samples.

Tricorder XThe other finalists include CloudDX, a Canadian company from Mississauga, Ontario; Danvantri, from Chennai, India; DMI from Cambridge, Mass; the Dynamical Biomarkers Group from Zhongli City, Taiwan; Final Frontier Medical Devices from Paoli, PA; MESI Simplifying Diagnostics from Ljubljana, Slovenia; SCANurse from London, England; and the Zensor from Belfast, Ireland.

In all cases, the entrants are compact, lightweight and efficient devices that push the information obtained through their multiple sensors to a smartphone or tablet interface. This appears to be done with a proprietary smartphone app via the cloud, where it can also be analyzed by a web application. Users will also be able to access their test results, discover information regarding possible symptoms and use big data to form a possible diagnosis.

 

qualcommtricorderchallenge-2

The next and final round of tests for the teams will take place next year between November and December. The scanners will be put through a diagnostic competition involving 15-30 patients whilst judges evaluate the consumers user experience. The final test will also assess the scanners’ adequacy in high-frequency data logging, and the overall winners will be announced in early 2016, and awarded the lucrative $10 million prize to develop their product and bring it to market.

If such a device could be simple enough to allow for self-diagnosis by the general public, it could play a key part in alleviating the pressure on overburdened healthcare systems by cutting down on unnecessary hospital visits. It will also be a boon for personalized medicine, making regular hospital visits quicker, easier, and much less expensive. And let’s not forget, it’s science fiction and Trekky-nerd gold!

Be sure to check out the video below that outlines the aims and potential benefits of the Qualcomm Tricorder XPRIZE challenge. And for more information on the finalists, and to see their promotional videos, check out the Qualcomm website here.

Anniversary of Canada Joining World War II

WWII_letsgocanadaposter75 years ago today, Canada joined its Commonwealth allies and declared war on Nazi Germany, signalling its entrance into the Second World War. And today, Canadians come together to celebrate and pay their respects to this national effort that saw a small nation rise to the greatest challenge in history, and commit sacrifices that would earn the respect of people the world over and stand the test of time.

The declaration came roughly a week after the German invasion of Poland on Sept. 1st, 1939 and the subsequent declaration of war by both Britain and France. Unlike the First World War, where Canada was obliged to become involved as part of the Commonwealth, Canada enjoyed a measure of self-determination in foreign affairs at this time and declared war autonomously. Though it was generally understood that Canada would become involved to support its allies, this decision was a significant event in the evolution of our nation.

British_Columbia_Regiment_1940Over the course of the next six years, Canada would enjoy a changing role in the war effort. Beginning the war as a largely unprepared participant, Canada would go on to become Britain’s most important ally for the next two years. Thereafter, Canadian forces would be a crucial arm of the British war effort, taking part in some of the toughest offensives on the Western Front and in both the air war and the war at sea.

Our first taste of combat came in the Battle of the Atlantic, which lasted from Sept. 1939 to war’s end in May of 1945. This would prove to be the longest battle of the war, and certainly one of the most crucial. Between the Royal Canadian Navy, the Canadian Merchant Navy, and the Royal Canadian Air Force (RCAF), thousands of Canadians fought and died to ensure the safe passage of troops and goods across the Atlantic to Britain.

operation-overlordThis not only ensured that Britain did not collapse during the darkest days of the war in 1940 and 41. From 1942 onward, it was part of the largest buildup in military history, which in turn led to the D-Day landings, the liberation of France, and victory in Europe. During the Battle of Normandy (June 6th – Aug. 25th, 1944), Canadian forces distinguished themselves in the Battle of Caen and the Falaise Pocket, two key operations that led to the defeat of the Nazis in France.

Between 1939 and 1945, Canada also made major contribution to the air war through the British Commonwealth Air Training Plan and the Royal Canadian Air Force. Given that Britain was vulnerable to air strikes from Germany early in the war, Canada became the site of the Commonwealth’s pilot training, and provided countless men and women with the skills they needed to fly fighters, bombers, supply planes and sub hunters.

battle_of_britainThe RCAF would also participate heavily in the Battle of Britain and combat operations in Europe, the north Atlantic, north Africa, southern Asia, and at home. By war’s end, it would be the fourth largest air force in the world. Similarly, the Royal Canadian Navy, which provided escort to British and Allied shipping across the Atlantic, was intrinsic in hunting U-boats, and would become the world’s fifth largest surface fleet by wars end.

In addition, Canada participated in some of the most costly and ugly defeats in the war. This included the Battle of Hong Kong, one of the first battles of the Pacific Campaign which occurred on the same morning as the attack on Pearl Harbor. Here, a total of 14,000 British, Canadian, Indian and Chinese troops faced off against 52,000 Japanese Imperial soldiers and were defeated. Those that survived were taken as slaves, while those countless others were mercilessly slaughtered.

dieppe-dsAnd on August 19th, 1942, the 2nd Canadian Infantry Division took part in one of the most poorly-planned operations of the war – the Dieppe Raid. Here, Canadian, British, Free French and Polish troops stormed a well-defended occupied port in Northern France and were forced to retreat. Of the nearly 5,000-strong Canadian contingent that went ashore, 3,367 were killed, wounded or taken prisoner – an exceptional casualty rate of 68%.

All told, a total of 1,187,334 Canadian men and women were mobilized to fight in the war from a population that numbered 11 million before the war. Afterward, Canada would go on to become a major voice for peacekeeping and human rights on the international stage. This was exemplified by John Peters Humphrey (a Canadian) being the principle drafter of the UN Universal Declaration of Human Rights, and Canadian troops participating in peacekeeping missions all around the world.

At the same time, some 45,400 Canadians would make the ultimate sacrifice to defeat Fascism, militarism, and genocide – close to half a percent of Canada’s total population. And I am honored to say that this past April, I was able to pay my respects at several Commonwealth cemeteries where many of them were laid to rest. This included Beny-sur-Mer, Ranville, and the Bayeux Commonwealth Cemetery.

My first cousin, twice removed, Wilmot Pettit was one of those individuals who did not make it home. As a member of the Royal Air Force, he was tasked with towing gliders into Normandy on D-Day as part of the Eastern Task Force. While flying over Grangues, his plane was shot down and he and his crew were killed. Today, his body rests at Ranville Cemetery, surrounded by many fellow Canadians and British soldiers who perished on that “Day of Days”.

Canada_ww2This past year has been an ongoing procession of anniversaries. From the seventieth anniversary of the Normandy Invasion, to the Centennial of the outbreak of World War I, to the seventy-fifth anniversary of World War II, and now the seventy-fifth of Canada entering the war… It certainly makes one feel thankful. At the same time, it reminds us of just how fragile peace and civility are – not to mention how important.

In today’s world, there are still many people who – either out of selfishness, stupidity, grief or ignorance – seek to cause harm or profit from violence. Sadly, these people often finds themselves at the head of an army of willing supplicants. One can only hope that something other than a global effort and a major expenditure of life will not be needed to stop them before it’s too late!

The Future is Here: DARPA’s Nervous System Implants

DARPA_implantHard on the heels of their proposed BRAIN initiative – a collaborative research initiative to map the activity of every neuron in the human brain – DARPA has announced a bold new program to develop tiny electronic implants that will be able to interface directly with the human nervous system to control and regulate many different diseases and chronic conditions, such as arthritis, PTSD, Crohn’s disease, and depression.

The program, called ElectRx (pronounced ‘electrics’), ultimately aims to replace medication with “closed-loop” neural implants which monitor the state of your health and then provide the necessary nerve stimulation to keep your organs and biological systems functioning properly. The work is primarily being carried out with US soldiers and veterans in mind, but the technology will certainly percolate down to civilians as well.

electrx-darpaThe ElectRx program will focus the relatively new area of medical therapies called neuromodulation, which seeks to modulate the nervous system to improve neurological problem. Notable examples of this are cochlear implants which restore hearing by modulating your brain’s auditory nerve system, and deep brain stimulation (DBS) which is apparently capable of curing/regulating conditions  like depression and Parkinson’s by overriding erroneous neural spikes.

So far, these implants have been fairly large, which makes implantation fairly invasive and risky. Most state-of-the-art implants also lack precision, with most placing the stimulating electrodes in roughly the right area, but which are unable to target a specific bundles of nerves. With ElectRx, DARPA wants to miniaturize these neuromodulation implants so that they’re the same size as a nerve fiber.

electrx-darpa-implant-diagramThis way they can be implanted with a minimally invasive procedure (through a needle) and attached to specific nerve fibers, for very precise stimulation. While these implants can’t regulate every condition or replace every medication (yet), they could be very effective at mitigating a large number of conditions. A large number of conditions are caused by the nervous system misfiring, like inflammatory diseases, brain and mental health disorders.

Currently, a variety of drugs are used to try and cajole these awry neurons and nerves back in-line by manipulating various neurotransmitters. However, the science behind these drugs is not yet exact, relying heavily on a trial-and-error approach and often involving serious side-effects. Comparatively, an electronic implant that could “catch” the misfire, cleans up the signal, and then retransmits it would be much more effective.

cochlear_implantAs DARPA’s Doug Weber explained:

The technology DARPA plans to develop through the ElectRx program could fundamentally change the manner in which doctors diagnose, monitor and treat injury and illness. Instead of relying only on medication — we envision a closed-loop system that would work in concept like a tiny, intelligent pacemaker. It would continually assess conditions and provide stimulus patterns tailored to help maintain healthy organ function, helping patients get healthy and stay healthy using their body’s own systems.

Despite requiring a lot of novel technological breakthroughs, DARPA is planning to perform human trials of ElectRx in about five years. The initial goal will be improving the quality of life for US soldiers and veterans. And while they have yet to announce which conditions they will be focusing on, it is expected that something basic like arthritis will be the candidate – though there are expectations that PTSD will become a source sooner other than later.

AI'sAnd this is just the latest neurological technology being developed by DARPA. Earlier in the year, the agency announced a similar program to develop a brain implant that can restore lost memories and experiences. A joint fact sheet released by the Department of Defense and the Veteran’s Association revealed that DARPA also secured 78 million dollars to build the chips as part of the government’s Brain Research through Advancing Innovative Neurotechnologies (BRAIN) program.

While DARPA’s ElectRx announcement is purely focused on the medical applications of miniature neural implants, there are of course a variety of other uses that might arise from elective implantation – for soldiers as well as civilians. With a few well-placed implants in a person’s spine, they could flip a switch and ignore any pain reported by your limbs, allowing them to withstand greater physical stress or ignore injuries.

posthumanImplants placed in muscle fibers could also provide added electrostimulation to provide extra boosts of raw muscle power. And With precision-placed implants around the right nerve fibers, people could gain manual control of their organs, allowing them to speed up or slow down their hearts, turbo-charge their livers, or tweak just about any other function of their bodies.

The age of the Transhuman looms, people!

Is the Universe One Big Hologram?

universe_nightsky“You know how I can tell we’re not in the Matrix?  If we were, the food would be better.” Thus spoke Sheldon Cooper, the socially-challenged nerd from The Big Bang Theory. And yet, there is actually a scientific theory that posits that the universe itself could be a 2D hologram that is painted on some kind of cosmological horizon and only pops into 3D whenever we observe it (aka. always).

And in what may be the most mind-boggling experiment ever, the US Department of Energy’s Fermi National Accelerator Laboratory (Fermilab) seeks to test this theory for the first time. Their tool for this is the Holometer, a device which has been under construction for a couple of years. It is now operating at full power and will gather data for the next year or so, at which time it will seek to uncover if the universe is a hologram, and what it’s composed of.

big_bangThe current prevailing theories about how the universe came to be are the Big Bang, the Standard Model of particle physics, quantum mechanics, and classical physics. These hypotheses and models don’t fully answer every question about how the universe came to be or continues to persist – which is why scientists are always investigating other ideas, such as supersymmetry or string theory.

The holographic universe principle is part of string theory – or at least not inconsistent with it – and goes something like this: From our zoomed out vantage point, the universe seems to be a perfectly formed enclave of 4D spacetime. But what happens if you keep zooming in, past the atomic and subatomic, until you get down to the smallest possible unit that can exist in the universe?

fermi_holometer-3In explaining their theory, the scientists involved make much of the analogy of moving closer to an old-style TV until you can see the individual pixels. The holographic principle suggests that, if you zoom in far enough, we will eventually see the pixels of the universe. It’s theorized that these universal pixels are about 10 trillion trillion times smaller than an atom (where things are measured in Planck units).

The Holometer at Fermilab, which on the hunt for these pixels of the universe, is essentially an incredibly accurate clock. It consists of a twin-laser interferometer, which – as the name suggests – extracts information from the universe by measuring interference to the laser beams. Each interferometer directs a one-kilowatt laser beam at a beam splitter and then down two 40-m (130-ft) arms located at right-angles to one another.

holometer-interferometer-diagramThese beams are then reflected back towards the source, where they are combined and analyzed for any traces of interference. As Craig Hogan, the developer of the holographic noise theory and a director at Fermilab, explained:

We want to find out whether space-time is a quantum system just like matter is. If we see something, it will completely change ideas about space we’ve used for thousands of years.

After any outside influences are removed, any remaining fluctuations – measured by slightly different frequencies or arrival times – could be caused by the ever-so-slight quantum jitter of these universal pixels. If these universal pixels exist, then everything we see, feel, and experience in the universe is actually encoded in these 2D pixels. One major difficulty in such a test will be noise – aka. “Holographic noise” – which they expect to be present at all frequencies.

fermi_holometerTo mitigate this, the Holometer is testing at frequencies of many megahertz so that motions contained in normal matter are claimed not to be a problem. The dominant background noise of radio wave interference will be the most difficult to filter out, according to the team. As Holometer lead scientist Aaron Chou explained:

If we find a noise we can’t get rid of, we might be detecting something fundamental about nature – a noise that is intrinsic to space-time.

This would have some serious repercussions. For a start, it would mean that spacetime itself is a quantum system, just like matter. The theory that the universe consists of matter and energy would be annulled, replaced with the concept that the universe is made of information encoded into these universal pixels, which in turn create the classical concepts of matter and energy.

fermi_holometer-1And of course, if the universe is just a 3D projection from a 2D cosmological horizon, where exactly is that cosmological horizon? And does this mean that everything we know and love is just a collection of quantum information carrying 2D bits? And perhaps most importantly (from our point of view at least) what does that make us? Is all life just a collection of pixels designed to entertain some capricious audience?

All good and, if you think about it, incredibly time-honored questions. For has it not been suggested by many renowned philosophies that life is a deception, and death an escape? And do not the Hindu, Buddhist and Abrahamic religions tells us that our material existence is basically a facade that conceals our true reality? And were the ancient religions not all based on the idea that man was turned loose in a hostile world for the entertainment of the gods?

Well, could be that illusion is being broadcast in ultra-high definition! And getting back to The Big Bang Theory, here’s Leonard explaining the hologram principle to Penny, complete with holograms:

The Future is Here: Sweat-Powered Smart Tatoo

smart_tatoosSmart tattoos are the hot ticket item of modern medicine, combining ultra-thin electronics with flexible materials. When they become commonplace, they will be a great way to monitor vital signs and health. The only thing that seems to be holding them back, is finding a way to power them. Tiny batteries are one possibility, but lack practicality, and microwaves are several years away from being feasible.

Luckily, Joseph Wang – a researchers from UCSD – has come up with a way to generate power for these devices without using any external equipment. The secret, is to harness electrons from lactate acid secreted in sweat. These acids are produced when our muscles work to exhaustion, a waste product that causes muscles to “burn”, but which the brain thrives upon. Hence why it is the endpoint in lactate’s metabolization cycle.

https://i0.wp.com/www.extremetech.com/wp-content/uploads/2014/08/Tattoo-640x353.jpgWhen lactate was discovered to be released in sweat, exercise physiologists began developing sensor technology to measure its levels in the sweat and blood. Wang has taken the next logical step of adding provisions to accumulate charge when lactate is enzymatically sensed. By embedding enzymes that process lactate into the tattoo, he was able to extract 70 microwatts per cm² of skin.

The only catch with this tattoo is that you need to be hot – as in pedaling your heart out on a bike for 30 minutes – to get the lactate out. That, however, may not be a barrier to this technology, since it is possible to selectively activate the sympathetic nerves that control the sweat glands in a discrete patch of skin. That way, you override the normal control and can sweat without the heat or exertion.

flexible_elecThe other part of the puzzle would be to actually generate the lactic acid. Preferably, this would be done locally as well, rather than having to have high levels circulating in the blood. But in the end, such steps would not even be necessary considering that a vitals and health monitoring that occurs into a workout – after an initial warm-up and good sweat have taken place – could be just what the doctor ordered (no pun intended!).

Other researchers have already imagined e-tattoos to read your thoughts and desires, either by reading unvocalized words or EEG readings. And compared to past generations of sensor devices, these tattoos represent a sophisticated electronic package with on-board signal processing and communications. With a discrete way to power such devices, a formidable tool for self discovery might be had.
