Recent Warfare Technologies

Moving electrical energy around is difficult, and while this article is predicted on the use of such materials in long distance transmission, having high efficiency wiring for vehicles makes such things as electric drive or electrical weaponry more feasible. A bonus is superconductors have no electrical field, so the power wiring harness is "quiet" and won't interfere with on board electronics or comms equipment:

Innovative Superconductor Fibers Carry 40 Times More than Copper

Researchers at Tel Aviv University have found a way to make an old idea new with the next generation of superconductors.

    Dr. Boaz Almog and Mishael Azoulay working in the group of Prof. Guy Deutscher at TAU's Raymond and Beverly Sackler School of Physics and Astronomy have developed superconducting wires using fibers made of single crystals of sapphire to be used in high powered cables. Factoring in temperature requirements, each tiny wire can carry approximately 40 times more electricity than a copper wire of the same size. They have the potential to revolutionize energy transfer, says Dr. Almog.

The properties of copper wires are listed here

High temperature superconducting wire usually carries 4-10 times the power of copper SuperPower state-of-the-art second-generation high temperature superconductor (2G HTS) wire can carry up to one hundred times as much current as conventional copper wire.

Beating the heat

One of the things that make our copper wires inefficient is overheating, Dr. Almog explains. Due to electrical resistance found in the metal, some of the energy that flows through the cables is cast off and wasted, causing the wires to heat up. But with superconductors, there is no resistance. A self-contained cooling system, which requires a constant flow of liquid nitrogen, keeps the wire in its superconducting state. Readily available, non-toxic, and inexpensive — a gallon of the substance costs less than a gallon of milk — liquid nitrogen provides the perfect coolant.

Even with the benefit of liquid nitrogen, researchers were still hard pressed to find a material that would make the ideal superconductor. Superconductors coated on crystal wafers are effective but too brittle, says Dr. Almog, and although superconductors on metallic tapes had some success, the product is too expensive to manufacture in mass quantities.

To create their superconductors, the researchers turned to sapphire fibers, developed by Dr. Amit Goyal at the Oakridge National Lab in Tennessee and lent to the TAU team. Coated with a ceramic mixture using a special technique, these single-crystal fibers, slightly thicker than a human hair, have made innovative superconductors.

Going macro

Dr. Almog is currently working to produce better superconductors that could transport even larger amounts of electric current.

One area where such superconductors could lend a hand is in collecting renewable energy sources. "Sources such as wind turbines or solar panels are usually located in remote places such as deserts or offshore lines, and you need an efficient way to deliver the current," explains Dr. Almog. These superconductors can traverse the long distances without losing any of the energy to heat due to electrical resistance.

Superconducting cables could also be an efficient way to bring large amounts of power to big cities "If you want to supply current for a section of a city like New York, you will need electric cables with a total cross-section of more than one meter by one meter. Superconductors have larger current capacities using a fraction of the space," says Dr. Almog. Different parts of a city could be cross-wired, he adds, so that in the event of a blackout, power can be easily rerouted.
 
Rapidly building shelters for bases, refugee camps and so on is always a logistical nightmare. This technology can bring the costs down dramatically (and imagine replacing ancient buildings on base for a small fraction of the current cost of replacing old structures):

A true bargain house
First prototype built from MIT’s effort to construct houses for $1,000 each.

September 15, 2011

Home prices in many of the world’s most famous cities run to well over $1,000 per square foot. By contrast, MIT architects have produced a decidedly more affordable alternative: the first prototype from the Institute’s “1K House” project, an effort to see if low-cost homes for the poor can be constructed for $1,000, total.

The prototype, called Pinwheel House, was designed by Ying chee Chui MArch ’11, a graduate of MIT’s Department of Architecture, and has been constructed in Mianyang, in Sichuan Province, China.

“It’s part of the responsibility of an architect, to create these spaces for people to live,” Chui says. “It’s from the heart.”

Chui first designed Pinwheel House in 2009 as part of the design studio — essentially a class — that launched the 1K House effort. The project is particularly focused on affordable housing for areas hit by natural disasters, such as the 2008 earthquake in Sichuan. This prototype turned out to be more costly, at $5,925, but is still very inexpensive in relative terms.

The idea to attempt building $1,000 homes was first conceived by Tony Ciochetti, the Thomas G. Eastman Chair at MIT’s Center for Real Estate, and inspired by One Laptop Per Child, the foundation headed by MIT professor Nicholas Negroponte that brings low-cost computers to children.

“There is a huge proportion of the world’s population that has pressing housing needs,” says Ciochetti, who first got the idea for the initiative after seeing a family of four emerge from a tiny mud hut while he was traveling through rural India. Like One Laptop Per Child’s aim of developing $100 computers, Ciochetti adds, the idea of the $1,000 house is intended as a challenge to designers: “Can you build affordable, sustainable shelter for such a large population?”

Pinwheel and courtyard

Chui’s house is one of 13 plans that emerged from the first 1K House design studio, in 2009. It features hollow brick walls with steel bars for reinforcement, wooden box beams, and is intended to withstand a magnitude 8.0 earthquake.

The Pinwheel House prototype was more expensive to build partly because it is larger than Chui’s original design — about 800 square feet, rather than 500 square feet. The smaller version of the house could be built for about $4,000, says Chui, now an architectural practitioner in New York City. That figure could be still lower if a large number of the homes were built at once, she adds.

In any case, the central design concept of Pinwheel House is the same: It has a modular layout, with rectangular room units surrounding a central courtyard space. “The module can be duplicated and rotated, and then it becomes a house,” Chui says. “The construction is easy enough, because if you know how to build a single module, you can build the whole house.”

Yung Ho Chang, a professor of architectural design at MIT who helped oversee the 2009 1K House design studio, thinks the prototype has fulfilled the promise of Chui’s design. “The house Chee built has good ventilation and good light,” Chang says.

Chang, for his part, is originally from China, and runs an independent practice there, Atelier FCJZ. He was attracted to the 1K House project, in part, by the shortage of good housing in some parts of his native country.

“After the earthquake, this project came as a natural thing to do,” Chang says. “It’s not just about how cheap the house is, but if it’s decent. When you look at living conditions in parts of China, India and Africa, they don’t meet the basic standards of what we think of as real housing.”

From $1K to $10K?

The 1K House project has proven successful enough, and attracted enough attention, that Chang is overseeing a related MIT design studio this fall, along with a number of outside collaborators. This one aims to create a series of home designs, intended for Japan, which would cost $10,000 to build. Participants in the studio include architects and designers from Tokyo University, the Japanese architecture firm Tsushima Design Studio, Atelier FCJZ, the Japanese retailer Muji, and Vanke, a real estate development firm in China.

“The idea of the 1K house is very much about how could we, as architects in research institutions like MIT, work on world poverty,” Chang says. “This semester, the mission is more about how design could reach a bigger percentage of the population, in the middle class.”

The new design studio also aims to create homes that could be built inexpensively following natural disasters, such as the earthquake and tsunami that struck northern Japan in March. Rebuilding in such situations, Chang says, often entails three stages of construction: the creation of temporary shelters, then stronger temporary homes sturdy enough for winter weather, and then permanent replacements for damaged or destroyed buildings.

During that process, Chang says, “there are a lot of resources wasted, including energy.” Alternately, he suggests, inexpensive and simple houses built from an existing template could let countries rebuild more quickly with practical, permanent structures.

The use of inexpensive housing for rebuilding is, in part, why architects in Japan are now engaging with the project. The initiative “is an important step in the realization of rapid/permanent community building,” says Andrew Wit, an architect with Tsushima Design Studio, responding to questions by email. After disasters, he adds, “the government very quickly builds shelters to house all of those affected by the events, but these cheap housing types have very short lifespans and are also made at very low quality standards … But the [MIT house project] asks if it is possible to utilize new technologies and processes for the quick creation of housing equal to or higher then the typical quality standards which are currently seen in Japan.”

Plenty of hurdles remain before any home can be manufactured for $1,000 or less. “If it were easy, somebody would have done it,” Ciochetti says.

But ultimately, Chang hopes, convening further studios in the vein of the 1K House project will allow more designs to move from the drawing board and onto solid ground. “The inexpensive laptop got to be more than an idea, it became available for children,” Chang says. “I hope one day we’ll be in the same position.”

Bullet proof skin anyone?

Imagine having a gun fired at you, the bullet whizzing toward you at a super-fast speed. But instead of the bullet piercing your skin and traveling deep inside your body, what if it instead repelled off your skin?

What sounds like a scenario straight out of a superhero movie or a sci-fi novel could eventually become reality. Scientists have created a skin made with goat's milk packed with spider-silk proteins, according to news reports. Their hope is that they can eventually replace the keratin in human skin --which makes it tough -- with the spider-silk proteins.

To make the bullet-proof material, Dutch scientists first engineered goats to produce milk that contains proteins from extra-strong spider silk. Then, using the milk from the goats, they spun a bullet-proof material; a layer of real human skin is then grown around that skin, a process that takes five weeks, the Daily Mail reported.

"Science-fiction? Maybe, but we can get a feeling of what this transhumanistic idea would be like by letting a bulletproof matrix of spidersilk merge with an in vitro human skin," researcher Jalila Essaidi told the Daily Mail.

Does it work? Well, the skin is only able to stop bullets fired at reduced speeds, TechNewsDaily reported. It was not able to stop a bullet from a .22 caliber rifle shot at a normal speed, which is the required standard for today's bulletproof vests.

The skin is currently on display at the National Natural History Museum Naturalis in Leiden, Netherlands, until Jan. 8, 2012, TechNewsDaily reported.

More research must be done before this bullet-proof "super skin" can actually be possible to engineer into humans.

High tech capacitors have been touted as replacement energy sources for electric and electronic equipment; more progress here:

First Energy-Storage Membrane

A team from the National University of Singapore’s Nanoscience and Nanotechnology Initiative (NUSNNI), led by principle investigator Dr Xie Xian Ning, has developed the world’s first energy-storage membrane.

    The new membrane promises greater cost-effectiveness in delivering energy, but also an environmentally-friendly solution. The researchers used a polystyrene-based polymer to deposit the soft, foldable membrane that, when sandwiched between and charged by two metal plates, could store charge at 0.2 farads per square centimeter. This is well above the typical upper limit of 1 microfarad per square centimetre for a standard capacitor.

    The cost involved in energy storage is also drastically reduced. With existing technologies based on liquid electrolytes, it costs about US$7 to store each farad. With the advanced energy storage membrane, the cost to store each farad falls to an impressive US$0.62. This translates to an energy cost of 10-20 watt-hour per US dollar for the membrane, as compared to just 2.5 watt-hour per US dollar for lithium ion batteries.

Polymer Physics - Supercapacitive energy storage based on ion-conducting channels in hydrophilized organic network

    Conventional electrode materials for supercapacitors are based on nanoscaled structures with large surface areas or porosities. This work presents a new electrode material, the so-called hydrophilized polymer network. The network has two unique features: 1) it allows for high capacitance (up to 400 F/g) energy storage in a simple film configuration without the need of high-surface-area nanostructures; 2) it is unstable in water, but becomes extremely stable in electrolyte with high ionic strength. The above features are related to the hydrophilizing groups in the network which not only generate hydrated ionic conduction channels, but also enable the cross-linking of the network in electrolyte. Because of its practical advantages such as easy preparation and intrinsic stability in electrolyte, the hydrophilized network may provide a new route to high-performance supercapacitive energy storage. © 2011 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 49: 1234–1240, 2011


    The performance of the membrane surpasses those of rechargeable batteries, such as lithium ion and lead-acid batteries, and supercapacitors.

    Potential applications: From hybrid vehicles to solar panels and wind turbines

    The membrane could be used in hybrid vehicles for instant power storage and delivery, thus improving energy efficiency and reducing carbon emission. Potentially, hybrid cars with the membrane technology could be powered by the energy stored in the membranes in conjunction with the energy provided by fuel combustion, increasing the lifespan of car batteries and cutting down on waste.

    The membrane could also be integrated into solar panels and wind turbines to store and manage the electricity generated. Energy provided through these sources is prone to instability due to their dependence on natural factors. By augmenting these energy sources with the membrane, the issue of instability could potentially be negated, as surplus energy generated can be instantly stored in the membranes, and delivered for use at a stable rate at times when natural factors are insufficient, such as a lack of solar power during night-time.

    Next Step

    The research team has demonstrated the membrane’s superior performance in energy storage using prototype devices. The team is currently exploring opportunities to work with venture capitalists to commercialise the membrane. To date, several venture capitalists have expressed strong interest in the technology.

    “With the advent of our novel membrane, energy storage technology will be more accessible, affordable, and producible on a large scale. It is also environmentally-friendly and could change the current status of energy technology,” Dr Xie said.

K-MAX unmanned chopper delivers Air Force salute to Afghan danger (video)

It's a year since Lockheed Martin won the contract to provide an unmanned cargo delivery system to the US military and now its first K-MAX helicopter is just about ready for duty. The 6,000-pound RC chopper is scheduled to journey to the manifold fronts of Afghanistan next month, where it'll get busy ferrying its own bodyweight in ammo and supplies to needy anthills up to 200km away. And, if things get too sticky for laptop flying, there's always room for a brave soul to jump in there and grab the controls. You'll find a fresh demo video after the break, plus we've also stuck in that fancy clip from last year to rotor your memory.

The Cell Tower That's Smaller Than a Bread Basket
Breakthrough innovator Tod Sizer's tiny cell antenna is a low-tech solution to the pressing problem of data overwhelming our existing cellular networks.
By Logan Ward

With predictions of a thirtyfold increase in mobile data demand by 2015, Tod Sizer, head of wireless research at Bell Labs, knew something had to give. "There's no way we can put up 30 times as many cell towers as there are today," he says. So he did what any high-tech engineer would do—he went to his wood shop. Sizer cut a 60-mm cube, attached an aluminum plate to represent an antenna and handed it to his team, telling them to rethink everything.

Their solution, the lightRadio cube, drastically shrinks the antenna and combines it with an amplifier to boost the signal. Digital-processing functions, which currently hunker in a building at a cell tower's base, will be consolidated in facilities up to 25 miles away. Sizer compares this Lego-block approach to multicore computer processors. "The future," he says, "is not about higher- and higher-power solutions. It's about lower-power solutions serving a smaller number of people with the same amount of data." According to the company, arrays of the cubes—affixed to skyscrapers, airport terminals, bus stops—can increase broadband capacity by 30 percent while cutting operation costs and energy consumption in half.

The lightRadio cube won't topple all towers—they'll still be needed along roadways and in rural areas—but it should greatly reduce their proliferation. It should also revolutionize cellphone service in the cities of resource-strapped developing countries.

Mesa Robotics' mini-tank is perfectly happy on point

The Acer ground-bot from Mesa Robotics does way more than your average 4,500-pound semi-autonomous mule. In addition to carrying kit and providing that extra bit of ballistic steel-deflecting cover, it also scans for IEDs using ground-penetrating radar and then autonomously switches into "flail" mode when it finds one -- digging up and detonating that critter with barely a break in its 6MPH stride. Did we mention it also acts as a landing pad for small drones? No? That's because the video after the break says it all. Cue obligatory guitars, game controllers and armchair gung-ho.

We can barely afford or manage the bandwidth we're using now.  Bandwidth will only get more expensive; hence why analog TV is dissapearing.  The supply vs demand will soon kick in; if it hasn't already.

The info will become more daunting.  The workable solution... bigger Ops staffs; which I understand as no one (except me) is in favour of.
 
Unless all these ops people will be riding around in UAV's and manning sensor posts ( ;)), they are going to be the biggest consumers of bandwidth around.

There are several tricks pointed out in this thread that *could* help manage the bandwidth problem, and of course during war, everyone will grab and use whatever bandwidth is available.

The real killer app will be training people to act and respond without receiving orders and updates when their bandwidth has been taken or compromised. Isn't that what our Manouevre Warfare "Doctrine" was all about?  >:D
 
I was struck after reading this post about the difference between our messed up procurement system and the speed with which these guys are doing things. We need a satellite communication system for the high arctic for our CF-35's and anything else which moves up there; imagine how long it will take through conventional means.

I am pretty sure that Canadians can do it much quicker and cheaper than a government project; a barracks box sized space telescope called "MOST" was built and launched for under $10 million, and like many NASA spacecraft, operated for years beyond the expected operating life. Heck, I imagine that there is probably enough talent signed up on Army.ca to undertake a project of this type.

The real point here is that we may really have to look far outside the box for the next decade or so while the economic crisis unwinds (i.e. the Global Economy deleverages and the various credit bubbles around the planet defleate) to quickly and cheaply develop capabilities that we desire. In another thread, I noted that a modern AFV *could* probably be run by a small number of inexpensive tablet computers and a large number of "apps"; compared to the various "bespoke" black boxes that make up most AFV electronics. Other examples could probably be found...

Welcome to Copenhagen Suborbitals
By Kristian von Bengtson  October 24, 2011  |  2:47 pm  |  Categories: Rocket Shop, Science Blogs

HEAT1X-Tycho BRahe launch 2011. Image: Bo Tornvig
Dear reader…

My name is Kristian von Bengtson, and I design and build spacecrafts.

I have so much to show you and share with you. A little over three years ago my life changed. Everything I have learned, taught myself, loved and wanted to do was suddenly merged together in a split second: building my own space rocket with the right partner and crew. The ultimate DIY project.

It was in May 2008 I founded Copenhagen Suborbitals together with my newfound friend Peter Madsen. I met Peter who, like me, was at a crossroads in life in terms of projects. He had just finished his last home-made submarine, and I was back from NASA doing work on space capsules. Within a few minutes we joined forces and inside Peter’s submarine, under water, we planned how to conquer the universe without a single dime in our pockets.


Without any chance of turning in a business plan, with a fraction of sense, to someone with money, we decided just to begin and to make this endeavor an open source and non-profit project. We wanted to leave it to people to decide if they wanted to donate some money.

Today three years later we are blessed with thousands of donors, many sponsoring companies, and about 30 fantastic and hard-working part-time specialists. In June 2011 we succeeded in launching our dummy manned space rocket into the air. It was hand-built at a price of approximately $100,000. It flew! Even though we encountered a trajectory anomaly, we were still able to communicate with the rocket. We were able to shut down the hybrid rocket engine, separate the spacecraft and deploy the parachutes. It was the success we so dearly wanted.

This is not a business, nor is it an attempt to race against being the first doing private space travel in Europe. It is truly a project pushing the limits of a small group of individuals.

Human space flight has always been “untouchable.” It has been for big companies or governments only to take on. But Copenhagen Suborbitals would like to show the world that it can be done by thinking unconventionally in all areas, not only in terms of research and development but also on the financial side. We want to find the old spirit of the pioneer and entrepreneur in ourselves and in the process hopefully inspire as many as possible.

We design and build everything from scratch using ordinary materials. We try to overcome the complex process of making a suborbital space rocket by letting the ordinary and plain be our guide, instead of letting the complex and extreme become our obstacles.

Today is yet a great day. I have been given the privilege to blog here on Wired.com about Copenhagen Suborbitals. I hope you will join me on this journey and never be afraid to send me feedback or even suggest how to solve our challenges. You will see it all. From thoughts and sketches to the actual production as it happens. Hopefully you will get to know how we are thinking and how we are working using classic trial and error processes.

Since you will be joining Copenhagen Suborbitals in the development process, you will see and hear things that might seem ridiculous. And sometimes it is. You might even be scared, frustrated and annoyed. Then please let me know! For now, take a look at www.copenhagensuborbitals.com.

Ten hours ago I arrived in New York City. Peter and I will be representing Copenhagen Suborbitals, which has been nominated for the World Technology Award 2011. Don’t know if we will beat the establishment, and I don’t really care. I am just happy to be back here where I used to live and study and am looking forward to talking to a lot of interesting folks.

And I am looking forward to meeting you again, very soon … right here on Wired.com.

Ad Astra,

Kristian von Bengtson

Video: Canadian Company Develops Solar Powered Plane/Blimp Cargo Hauler
OCTOBER 24, 2011 BY CHRISTOPHER DEMORRO 14 COMMENTS

Green energy presents so many amazing opportunities and advantages over our current energy infrastructure…like the ability to go places where there isn’t any infrastructure. A Canadian company has developed a lightweight plane/blimp that can haul up to 1,000 kg of goods and is powered solely by the sun.

Flying Close To The Sun
The company, called Solar Ship, has developed a lightweight plane that can take off and land in the space of a football field. Big deal, so what right? Totally impractical…oh, wait, it can carry over 1,000 kg/2,200 lbs of stuff a distant of about 1,000 kilometers/620 miles? Well now, that certainly is impressive, and opens up a whole word of possibilities.

Some ideas for ways to use the Solar Ship are as an emergency rescue video to remote parts of the world where disaster strikes. They could also be used to deliver resources to distant mining or hunting outposts…though I wonder what happens should you fly under a big, dark cloud…

Hauler For Humanity
The blimp-part of the plane holds a lot of helium…but not enough to lift the plane on its own. An electric motor, powered by a battery that is charged by solar panels on the blimp’s back, allow the Solar Ship to take off and land in less than 100 yards, and it can be filled with enough helium to allow it to carry over a ton of supplies. Compared to other electric aircraft, which can only transport a few passengers short distances, the Solar Ships seem to have a practical purpose.

So far the smallest version of the Solar Ship, called the Caracal, has been built and can lift over a ton of materials. The designers envision it as useful in situations like those that followed the Haiti earthquake. With the main airstrip ruined, it took 8 days for supplies to be flown in. But the little Solar Ship can land just about anywhere, and while it can’t ferry much compared to a jumbo jet, a little bit can go a long way right after a disaster, and bigger versions are planned that could lift as much as 30 tons of material.

While the first test is already under its belt, more tests are required before production can take place, with runs planned for 2012 and 2013. It will be interested to see how these Solar Ships shape up.

A company called Aireon came up with something like this in the late 1960's/early 1970's (assisted lift, but without the solar part). If this can be made to work, this could be an interesting utility/logistics vehicle, or basis for a UAV platform.

(edit to add)

For military purposes, a solar powered airship would be rather limited, but the point of assisted lift (the helium negates most of the weight of the vehicle) is to allow a much smaller engine to be used. A small four cylinder diesel engine from a Volkswagon Golf would probably provide more than enough power for these airships (and bigger engines or turbocharged versions can provide the motivation for larger versions). A cargo carrier that can move a metric ton of supplies and is not tied to the road network, but only needs the fuel to power a small car engine will have some pretty impressive effecs for the logistics chain.
 
Could have used something like this during the G-20 summit. Black Block movment people, Caledonia and OWS are other prime examples where monitoring or phone shut downs would help law enforcement a great deal:

UK Cops Using Fake Mobile Phone Tower to Intercept Calls, Shut Off Phones
By Kim Zetter  October 31, 2011  |  6:53 pm  |  Categories: Surveillance

Britain’s largest police force has been using covert surveillance technology that can masquerade as a mobile phone network to intercept communications and unique IDs from phones or even transmit a signal to shut off phones remotely, according to the Guardian.

The system, made by Datong in the United Kingdom, was purchased by the London Metropolitan police, which paid $230,000 to Datong for “ICT hardware” in 2008 and 2009.

The portable device, which is the size of a suitcase, pretends to be a legitimate cell phone tower that emits a signal to dupe thousands of mobile phones in a targeted area. Authorities can then intercept SMS messages, phone calls and phone data, such as unique IMSI and IMEI identity codes that allow authorities to track phone users’ movements in real-time, without having to request location data from a mobile phone carrier.

In the case of intercepted communications, it is not clear whether the network works as a blackhole where intercepted messages go to die, or whether it works as a proper man-in-the-middle attack, by which the fake tower forwards the data to a real tower to provide uninterrupted service for the user.

In addition to intercepting calls and messages, the system can be used to effectively cut off phone communication, such as in a war zone where phones might be used as a trigger for an explosive device, or for crowd control during demonstrations and riots where participants use phones to organize.


The Met police would not provide details to the Guardian about where or when its technology had been used.

According to the company’s web site, Datong “develops intelligence solutions for international military, law enforcement and intelligence agencies for use in all operating environments,” and sells its products in the U.S. as well.

Between 2004 and 2009, Datong won over $1.6 million in contracts with the U.S. Secret Service, Special Operations Command, the Bureau of Immigration and Customs Enforcement and other agencies. In February 2010, the company won a $1.2 million contract to supply tracking and location technology to the U.S. defense industry. It also sells technology to regimes in the Middle East.

A spokesman for the U.S. Secret Service verified to CNET that the agency has done business with Datong, but would not say what sort of technology it bought from the company.

The FBI is known to use a similar technology called Triggerfish, which also pretends to be a legitimate cell tower base station to trick mobile phones into connecting to it. The Triggerfish system, however, collects only location and other identifying information, and does not intercept phone calls, text messages, and other data.

Last year at the DefCon hacker conference in Las Vegas, security researcher Chris Paget demonstrated a low-cost, home-brewed device that mimics the IMSI catchers that U.S. law enforcement agencies use.

The device spoofs a legitimate GSM tower and emits a signal that’s stronger than legitimate towers in the area to entice cell phones to route their outbound calls through the spoofed tower, allowing an attacker to intercept and record calls before they’re routed on their proper way through voice-over-IP.
 
Nice.  But I'd wager something of that sort is already in town and working....

2,400 Miles in Minutes? No Sweat! Hypersonic Weapon Passes ‘Easy’ Test

For a test of a hypersonic weapon flying at eight times the speed of sound and nailing a target thousands of miles away, this was a relatively simple demonstration. But it worked, and now the military is a small step closer to its dream of hitting a target anywhere on Earth in less than an hour.

The last time the Pentagon test-fired a hypersonic missile, back in August, it live-tweeted the event — until the thing crashed into the Pacific Ocean. This time around, it kept the test relatively quiet. The results were much better.

To be fair, this was also an easier test to pass. Darpa’s Falcon Hypersonic Technology Vehicle 2 — the one that splashed unsuccessfully in the Pacific — was supposed to fly 4,100 miles. The Army’s Advanced Hypersonic Weapon went about 60 percent as far, 2,400 miles from Hawaii to its target by the Kwajalein Atoll in the South Pacific. Darpa’s hypersonic glider had a radical, wedge-like shape: a Mach 20 slice of deep dish pizza, basically. The Army’s vehicle relies on a decades-old, conventionally conical design. It’s designed to fly 6,100 miles per hour, or a mere eight times the speed of sound.

But even though the test might have been relatively easy, the Advanced Hypersonic Weapon effort could wind up playing a key role in the military’s so-called “Prompt Global Strike” effort to almost instantly whack targets half a world away. A glider like it would be strapped to a missile, and sent hurtling at rogue state’s nuclear silo or a terrorist’s biological weapon cache before it’s too late.

At first, the Prompt Global Strike involved retrofitting nuclear missiles with conventional warheads; the problem was, the new weapon could’ve easily been mistaken for a doomsday one. Which meant a Prompt Global Strike could’ve invited a nuclear retaliation. No wonder Congress refused to pay for the project.

So instead, the Pentagon focused on developing superfast weapons that would mostly scream through the air, instead of drop from space like a nuclear warhead. Those hypersonic gliders may cut down on the geopolitical difficulties, but introduced all sorts of technical ones. We don’t know much about the fluid dynamics involved when something shoots through the atmosphere at hypersonic speeds. And there really aren’t any wind tunnels capable of replicating those often-strange interactions.

“You have to go fly,” says retired Gen. James “Hoss” Cartwright, who helped lead the Prompt Global Strike push as vice chairman of the Joint Chiefs of Staff and as head of U.S. Strategic Command. “You have to open up the envelope of knowledge.”

Darpa and the Air Force worked on understanding the aerodynamics of hypersonic flight — that’s one of the reasons behind the ill-fated Falcon Hypersonic Technology Vehicle tests. Meanwhile, the Army concentrated on controlling the hypersonic glider, and on thermal management. Moving through the air at Mach 8 generates a huge amount of heat. The military was keen to see if the carbon composite coating on the Advanced Hypersonic Weapon could take it. The last thing the Pentagon wants is for its Prompt Global Strike weapon to burn up before hitting its target.

Judging from yesterday’s test, it looks like the carbon composite held up. And so the plan to take out enemies from continents away just got a little easier to pull off.

Stuff like this also seems to be able to support long range doctrine like AirSea Battle as well.
 
That's a scramjet, that could look like the pic below.

Here's a wiki link that describes the technology.

http://en.wikipedia.org/wiki/Scramjet

No explosives required.  100lbs of solid shot at mach 7 will work just fine.  Likely great for hard installations.

Not too sure about hitting ships.  I do believe that this would demand accurate GPS coords, and the target would have to be static.
 
Imagine thousands of cooperative robots for EOD or engineering tasks (among other things)

Kilobots are leaving the nest
November 21, 2011

Swarm of tiny, collaborative robots will be made available to researchers, educators, and enthusiasts

CONTACT: Michael Patrick Rutter, (617) 496-3815

The Kilobots are coming.

Computer scientists and engineers at Harvard University have developed and licensed technology that will make it easy to test collective algorithms on hundreds, or even thousands, of tiny robots.

Called Kilobots, the quarter-sized bug-like devices scuttle around on three toothpick-like legs, interacting and coordinating their own behavior as a team. A June 2011 Harvard Technical Report demonstrated a collective of 25 machines implementing swarming behaviors such as foraging, formation control, and synchronization.

Once up and running, the machines are fully autonomous, meaning there is no need for a human to control their actions.

The communicative critters were created by members of the Self-Organizing Systems Research Group led by Radhika Nagpal, the Thomas D. Cabot Associate Professor of Computer Science at the Harvard School of Engineering and Applied Sciences (SEAS) and a Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard. Her team also includes Michael Rubenstein, a postdoctoral fellow at SEAS; and Christian Ahler, a fellow of SEAS and the Wyss Institute.

Thanks to a technology licensing deal with the K-Team Corporation, a Swiss manufacturer of high-quality mobile robots, researchers and robotics enthusiasts alike can now take command of their own swarm.

One key to achieving high-value applications for multi-robot systems in the future is the development of sophisticated algorithms that can coordinate the actions of tens to thousands of robots.

"The Kilobot will provide researchers with an important new tool for understanding how to design and build large, distributed, functional systems," says Michael Mitzenmacher, Area Dean for Computer Science at SEAS.

"Plus," he adds, "tiny robots are really cool!"

The name "Kilobot" does not refer to anything nefarious; rather, it describes the researchers' goal of quickly and inexpensively creating a collective of a thousand bots.

Inspired by nature, such swarms resemble social insects, such as ants and bees, that can efficiently search for and find food sources in large, complex environments, collectively transport large objects, and coordinate the building of nests and other structures.

Due to reasons of time, cost, and simplicity, the algorithms being developed today in research labs are only validated in computer simulation or using a few dozen robots at most.

In contrast, the design by Nagpal's team allows a single user to easily oversee the operation of a large Kilobot collective, including programming, powering on, and charging all robots, all of which would be difficult (if not impossible) using existing robotic systems.

So, what can you do with a thousand tiny little bots?

Robot swarms might one day tunnel through rubble to find survivors, monitor the environment and remove contaminants, and self-assemble to form support structures in collapsed buildings.

They could also be deployed to autonomously perform construction in dangerous environments, to assist with pollination of crops, or to conduct search and rescue operations.

For now, the Kilobots are designed to provide scientists with a physical testbed for advancing the understanding of collective behavior and realizing its potential to deliver solutions for a wide range of challenges.

More here and now stuff; lightweight, modular armour. I like the built in holster, but that's me...

U.S. PALM Defender Body Armor
U.S. PALM's Defender body armor was designed with civilians in mind and is a great item to have stored next to your home-defense firearm.
By Bob Owens (RSS)
November 21, 2011

You snap awake in the middle of the night, your pulse racing. You aren’t sure why, and then you suddenly hear the unmistakable sound of glass breaking downstairs. You slip your pistol from the safe in your nightstand drawer and grab the flashlight you keep by your bed for emergencies, moving to take position in the bedroom door where you have a commanding view of the hallway. This won’t end well for someone, but can you make sure that someone isn’t you?

In a potentially life-or-death scenario like a home invasion, both criminal and homeowner have advantages and disadvantages. When it’s your home, however, wouldn’t you prefer to maximize your tactical supremacy? U.S. PALM has decided the advantage should decisively go to the defender… or rather, the Defender.

Instead of grabbing your gun and running to the sound of a broken window or kicked-in door, put this vest on first, and you’ll gain a psychological edge from the knowledge that you are at least somewhat protected.

The Defender is a simple body armor concept, perfectly executed in rugged black, MultiCam, coyote brown or Ranger Green 500D Cordura nylon. A single, IIIA, soft body armor panel (available in large or extra-large) covers the vital chest area, riding on a pair of padded, adjustable shoulder straps. A simple wrap-around strap cinches the armor around your midsection. Best of all, you are “good to go” in about the time it takes to read this paragraph—or about 5 seconds.

The basic back panel is unarmored, but it can carry a second armor panel if the user so desires. In addition, the soft armor can be swapped out for most 10×12-inch Level IV hard-armor plates in both the front and rear, giving the user multiple-shot protection against even rifle fire.
The Defender variant I have on hand is the Handgun Defender. It mounts a universal holster (which fits most pistols, with or without an attached weaponlight) atop three universal handgun mag pouches (one on the right, two on the left). The magazine pouches could also conceivably carry a tactical flashlight or pepper spray canister without any problem at all. The vest also has a small admin pouch at the top of the vest.
U.S. PALM makes other Defender variants, including three models designed to carry rifle magazines for the AR-15, AK-47 and .308 Win.-chambered semi-automatics like the AR-10.

In addition, the company offers a MOLLE version on which you can add your own pouches, and a slick version without any pouches at all for wearing beneath clothing.

All Defender vests feature a common rear panel with a MOLLE strip across the back (not a bad spot for your IFAK or tourniquet), and two pouches ideal for carrying emergency supplies. The single-panel Defender weighs just 1.6 pounds, while the dual panel model tips the scales at 3 pounds.
The single 10×12.5-inch armor-panel vests retail for $199 ($249.99 for the 11×13.5-inch XL version), and the dual-panel variants with front and back Level IIIA  panels retail for $99 more ($124.99 more for XL), which makes the Defender series a steal when it comes to body armor.

It must be noted that the Defender lacks the wrap-around side protection of many soft-armor systems typically worn by military and law enforcement personnel, but that is by design. The Defender series was conceived for those who do not need to wear a vest all the time, but who may need to don one quickly. Home defenders also tend to know what direction home invaders are coming from, and a homeowner in a good defensive position is is mostly likely to be facing the threat, head-on.

Another possible alternative for those who like U.S. PALM’s armor concept—but feel they simply must have side protection in a relatively quick-donning vest—is the Desert Tracker Plate Carrier, which was originally designed to address a specific law enforcement problem.

Police officers in the American Southwest face desert heat that can be every bit as deadly as a criminal’s bullet. As a result, they’ve sometimes chosen not to wear body armor to minimize the possibility of heat stroke or heat exhaustion resulting from wearing heat-trapping body armor for long periods of time in the desert sun.

U.S. PALM’s Desert Tracker features a front vest panel designed to carry a SAPI or ESAPI rifle plate, and sides that can carry Level IIIA  6×6-inch soft armor for added flank protection. The back of the vest is open for ventilation, and the shoulder straps, front and side panels are lined with a moisture-wicking mesh on padded backing. It is available as either a MOLLE version, which is what I have for review, or with three double-magazine pouches holding six AR-style magazines in total. Colors offered include MultiCam, Ranger Green, coyote brown and an Italian special operations desert camouflage pattern called CB62 that works very well in the American Southwest, where this plate carrier was designed to operate. The only issue some civilians may have with the $249.99 Desert Tracker is it comes as the plate carrier only, with the user needing to provide armor of their own.
Both the Defender series and the Desert Tracker provide purpose-built armor carriage for specific customers, and you’d be hard pressed to find anyone else making equipment that hits these niches at such attractive prices.

As a civilian far away from the desert, relatively unlikely to come upon a cartel gunman crossing the border with an AK-47 in hand, I admittedly don’t have the need of the Desert Tracker. But, we buy car insurance, medical insurance and home insurance hoping that we’ll never have occasion to use them. The Defender just makes sense as part of your conflict insurance—an insurance plan that includes your firearm(s) and training. Understood with this context in mind, the most surprising thing about the U.S. PALM Defender is that a lightweight, easy-to-use and relatively inexpensive armor vest has taken so long to arrive.

Rebuilding the brain’s circuitry
Healthy neurons can integrate into diseased areas

“The next step for us is to ask parallel questions of other parts of the brain and spinal cord, those involved in ALS and with spinal cord injuries. In these cases, can we rebuild circuitry in the mammalian brain? I suspect that we can,” said Jeffrey Macklis, Harvard University professor of stem cell and regenerative biology.

Neuron transplants have repaired brain circuitry and substantially normalized function in mice with a brain disorder, an advance indicating that key areas of the mammalian brain are more reparable than was widely believed.

Collaborators from Harvard University, Massachusetts General Hospital (MGH), Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School (HMS) transplanted normally functioning embryonic neurons at a carefully selected stage of their development into the hypothalamus of mice unable to respond to leptin, a hormone that regulates metabolism and controls body weight. These mutant mice usually become morbidly obese, but the neuron transplants repaired defective brain circuits, enabling them to respond to leptin and thus experience substantially less weight gain.
Repair at the cellular-level of the hypothalamus — a critical and complex region of the brain that regulates phenomena such as hunger, metabolism, body temperature, and basic behaviors such as sex and aggression — indicates the possibility of new therapeutic approaches to even higher-level conditions such as spinal cord injury, autism, epilepsy, ALS  (Lou Gehrig’s disease), Parkinson’s disease, and Huntington’s disease.

In 2005, Harvard Medical School Dean Jeffrey Flier, then the George C. Reisman professor of medicine at BIDMC, published a landmark study showing that an experimental drug spurred the addition of new neurons in the hypothalamus and offered a potential treatment for obesity.

“There are only two areas of the brain that are known to normally undergo ongoing large-scale neuronal replacement during adulthood on a cellular level — so-called ‘neurogenesis,’ or the birth of new neurons — the olfactory bulb and the subregion of the hippocampus called the dentate gyrus, with emerging evidence of lower level ongoing neurogenesis in the hypothalamus,” said Jeffrey Macklis, Harvard University professor of stem cell and regenerative biology and HMS professor of neurology at MGH, and one of three corresponding authors on the paper. “The neurons that are added during adulthood in both regions are generally smallish and are thought to act a bit like volume controls over specific signaling.  Here we’ve rewired a high-level system of brain circuitry that does not naturally experience neurogenesis, and this restored substantially normal function.”

The two other senior authors on the paper are Jeffrey Flier, dean of Harvard Medical School, and Matthew Anderson, HMS professor of pathology at BIDMC.

The findings are to appear Nov. 25 in Science.

In 2005, Flier, then the George C. Reisman professor of medicine at BIDMC, published a landmark study, also in Science, showing that an experimental drug spurred the addition of new neurons in the hypothalamus and offered a potential treatment for obesity. But while the finding was striking, the researchers were unsure whether the new cells functioned like natural neurons.
Macklis’ laboratory had for several years developed approaches to successfully transplanting developing neurons into circuitry of the cerebral cortex of mice with neurodegeneration or neuronal injury. In a landmark 2000 Nature study, the researchers demonstrated induction of neurogenesis in the cerebral cortex of adult mice, where it does not normally occur. While these and follow-up experiments appeared to rebuild brain circuitry anatomically, the new neurons’ level of function remained uncertain.

To learn more, Flier, an expert in the biology of obesity, teamed up with Macklis, an expert in central nervous system development and repair, and Anderson, an expert in neuronal circuitries and mouse neurological disease models.
The groups used a mouse model in which the brain lacks the ability to respond to leptin. Flier and his lab have long studied this hormone, which is mediated by the hypothalamus. Deaf to leptin’s signaling, these mice become dangerously overweight.

Prior research had suggested that four main classes of neurons enabled the brain to process leptin signaling. Postdocs Artur Czupryn and Maggie Chen, from Macklis’ and Flier’s labs, respectively, transplanted and studied the cellular development and integration of progenitor cells and very immature neurons from normal embryos into the hypothalamus of the mutant mice using multiple types of cellular and molecular analysis. To place the transplanted cells in exactly the correct and microscopic region of the recipient hypothalamus, they used a technique called high-resolution ultrasound microscopy, creating what Macklis called a “chimeric hypothalamus” — like the animals with mixed features from Greek mythology.
Postdoc Yu-Dong Zhou, from Anderson’s lab, performed in-depth electrophysiological analysis of the transplanted neurons and their function in the recipient circuitry, taking advantage of the neurons’ glowing green from a fluorescent jellyfish protein carried as a marker.

These nascent neurons survived the transplantation process and developed structurally, molecularly, and electrophysiologically into the four cardinal types of neurons central to leptin signaling. The new neurons integrated functionally into the circuitry, responding to leptin, insulin, and glucose. Treated mice matured and weighed approximately 30 percent less than their untreated siblings or siblings treated in multiple alternate ways.
The researchers then investigated the precise extent to which these new neurons had become wired into the brain’s circuitry using molecular assays, electron microscopy for visualizing the finest details of circuits, and patch-clamp electrophysiology, a technique in which researchers use small electrodes to investigate the characteristics of individual neurons and pairs of neurons in fine detail. Because the new cells were labeled with fluorescent tags, postdocs Czupryn, Zhou, and Chen could easily locate them.

The Zhou and Anderson team found that the newly developed neurons communicated to recipient neurons through normal synaptic contacts, and that the brain, in turn, signaled back. Responding to leptin, insulin and glucose, these neurons had effectively joined the brain’s network and rewired the damaged circuitry.

“It’s interesting to note that these embryonic neurons were wired in with less precision than one might think,” Flier said. “But that didn’t seem to matter. In a sense, these neurons are like antennas that were immediately able to pick up the leptin signal. From an energy-balance perspective, I’m struck that a relatively small number of genetically normal neurons can so efficiently repair the circuitry.”

“The finding that these embryonic cells are so efficient at integrating with the native neuronal circuitry makes us quite excited about the possibility of applying similar techniques to other neurological and psychiatric diseases of particular interest to our laboratory,” said Anderson.
The researchers call their findings a proof of concept for the broader idea that new neurons can integrate specifically to modify complex circuits that are defective in a mammalian brain.

The researchers are interested in further investigating controlled neurogenesis — directing growth of new neurons in the brain from within — the subject of much of Macklis’ research as well as Flier’s 2005 paper, and a potential route to new therapies.

“The next step for us is to ask parallel questions of other parts of the brain and spinal cord, those involved in ALS and with spinal cord injuries,” Macklis said. “In these cases, can we rebuild circuitry in the mammalian brain? I suspect that we can.”

This study was funded by the National Institutes of Health, the Jane and Lee Seidman Fund for Central Nervous System Research, the Emily and Robert Pearlstein Fund for Nervous System Repair, the Picower Foundation, the National Institute of Neurological Disorders and Stroke, Autism Speaks, and the Nancy Lurie Marks Family Foundation.
