Pokemon Go and other games will be the nexus of making the augmented reality everywhere and gaming enhancing wearables on everyone

Pokemon Go became the top US mobile game within days of its launch. Many see it reaching 1 billion global installs to surpass the 550 million peak of Candy Crush. Pokemon Go and the follow on Mario and Zelda augmented reality games could get to over 1.6 billion mobile phone installs to surpass Facebook.

Nintendo plans to release four more smartphone app games by March 2017, and investors remarked that Pokémon Go showed Nintendo still has some of the "most valuable character intellectual property in the world" with franchises such as Super Mario, The Legend of Zelda, and Metroid.



The Pokémon Go Plus is a Bluetooth low energy wearable device that allows the player to traverse the game map without seeing it, i.e. without looking at their smart device. When the player is near a Pokémon or PokéStop, the Plus vibrates. The player can then press the button to capture the Pokémon blindly; the player cannot check what they have caught until the haptic device is is connected to an appropriate mobile device or tablet. It is set for release sometime in July 2016. The design is a combination of a Poké Ball and the shape of the Google Maps pin. The Plus, which had a pre-order cost of $34.99, was being listed on eBay for over $100 after Amazon, GameStop and the official Pokémon store sold out.

The decision to create the device rather than create a smart watch app was to increase uptake among players for whom a smart watch is prohibitively expensive.

Star Wars augmented reality could be big with light sabers connected to Google Glass like devices

A combination of super-viral augmented reality games could collectively revolutionize wearables and smart connected toys and get very high levels of adoption for multiple game specific wearables.

Motion sensors would also interact with the wearables and augmented games.



DARPA and Air Force Research making progress to mind controlled and autonomous drone swarms with prototype flight launches targeting 2020

A researcher at Arizona State University has discovered how to control multiple robotic drones using the human brain.

A controller wears a skull cap outfitted with 128 electrodes wired to a computer. The device records electrical brain activity. If the controller moves a hand or thinks of something, certain areas light up.

“I can see that activity from outside,” said Panagiotis Artemiadis (pictured above), director of the Human-Oriented Robotics and Control Lab and an assistant professor of mechanical and aerospace engineering in the School for Engineering of Matter, Transport and Energy in the Ira A. Fulton Schools of Engineering. “Our goal is to decode that activity to control variables for the robots.”

Panagiotis Artemiadis runs the university's Human-Oriented Robotics and Control Lab, where researchers seek to understand and improve interactions between humans and robots. The lab was awarded grants totaling $860,000 from the Defense Advanced Research Projects Agency and U.S. Air Force in 2014 to build out the mind-control technology.

If the user is thinking about decreasing cohesion between the drones — spreading them out, in other words — “we know what part of the brain controls that thought,” Artemiadis said.

A wireless system sends the thought to the robots. “We have a motion-capture system that knows where the quads are, and we change their distance, and that’s it,” he said.

Up to four small robots, some of which fly, can be controlled with brain interfaces. Joysticks don’t work, because they can only control one craft at a time.

“You can’t do something collectively” with a joystick, Artemiadis said. “If you want to swarm around an area and guard that area, you cannot do that.”

To make them move, the controller watches on a monitor and thinks and pictures the drones performing various tasks.




DARPA Invests $7.5 Million for Implantable Biosensor that are 3 millimeters long and 500 microns in diameter

Profusa (South San Francisco, CA) has won a $7.5 million grant from the Defense Advanced Research Projects Agency (DARPA) and the U.S. Army Research Office for further development of its tissue integrated biosensor technology, the company said Tuesday.

The U.S. military sees value in the technology improving mission efficiency through real-time monitoring of combat soldier health status.

"Profusa's vision is to replace a point-in-time chemistry panel that measures multiple bio­markers, such as oxygen, glucose, lactate, urea, and ions with a biosensor that provides a continuous stream of wireless data," Ben Hwang, PhD, Profusa's chairman and CEO, said in a news release.

The sensors are made of a bioengineered "smart hydrogel" that is similar to contact lens material, forming a porous, tissue-integrating scaffold. When exposed to light, the hydrogel is able to luminesce in proportion to the concentration of a specific chemical—oxygen, glucose, or another biomarker.


Profusa’s unique bioengineering approach overcomes the largest hurdle in long-term use of biosensors in the body: the foreign body response. Approximately 3 to 5 mm long and 500 microns in diameter, each tiny biosensor is a soft, flexible fiber designed to be biologically compatible with the body’s tissues for long-term monitoring up to two years while overcoming the effects of local inflammation or rejection.


Adhered to the skin’s surface or held by hand, a separate optical reader is used to read the fluorescent signal from the embedded biosensor. The reader sends excitation light through the skin to the biosensor, which then emits fluorescent light proportional to the amount of biochemical measured.

Profusa’s technology platform enables the development of biosensor systems with a variety of form factors serving consumer as well as medical applications for continuous monitoring of body chemicals. Results from the optical reader are designed to be transmitted to a smart phone application that allows the user to make actionable decisions, from improving their general health and well-being, to taking their athleticism to another level, or managing a chronic disease such as diabetes or COPD. Data can be shared securely via HIPAA-compliant digital networks with healthcare providers and public health analysts conducting longitudinal studies.

France calls on all willing citizens to become reservists

French Interior Minister Bernard Cazeneuve has called on citizens to become reservists, in a bid to help boost security forces in the wake of the country's latest terror attack.

France's "operational reservists" include French citizens with or without military experience as well as former soldiers.

"I want to call on all French patriots who wish to do so, to join this operational reserve," Cazeneuve said.

His call comes after the government has been criticized for not doing more to stop attacks.

French President Francois Hollande said on Friday that reservists would be called upon to boost the ranks of police and gendarmes.

The operational reserve is currently made up of 12,000 volunteers, 9000 of whom are within the paramilitary police and 3000 in the regular police force, said Cazeneuve.

"We are going to reinforce the presence of security forces across the country," he added.

He said the number of security forces deployed to protect the population was nearly 100,000, including 53,000 police, 36,000 para-military police and 10,000 soldiers.




Reviewing where World War 3 could breakout ?

What are the most likely places for world war 3 to breakout ? The cold war had a more clear matchup between NATO and the Soviet Union with the most likely breakout being in Europe. Now there are many possible breakout locations.

Global tensions and conflicts give the feeling like you are reading a history book and are in the chapter just before the big war. The period where there are conflicts and tensions building but little resolutions.

The Council on Foreign Relations tracks all of the current global conflict hotspots

There are several reviews of what could be a flashpoint for the next global war aka World war 3.


North Korea

A few days ago North Korea (DPRK) threatened to reduce Japan “to debris” as it considers invading the country.

Pyongyang-based newspaper Rodong Sinmun, which is the official publication for the hermit state’s one-party government, promised the nation possessed the weapons to carry out its attack – in response to a Japanese military drill.

The editorial accused Japan of working with South Korean officials, described as “the worst group of traitors”, as part of a plan to invade the country.

Last weekend the state promised to turn South Korea into “a sea of fire and a pile of ashes” after its neighbor and the United States moved to deploy a missile defense system near its territory.

North Korea has nuclear bombs and is working on submarine launched missiles and intercontinental missiles.

In January 2016, North Korea conducted its fourth nuclear weapons test, claiming to have detonated its first hydrogen bomb. However, analysis of the seismic readings and radiation left doubt as to what type of weapon was actually tested. Continuing to defy international sanctions, in February 2016 Pyongyang fired a long-range rocket to launch a satellite in to orbit, which was widely viewed as continued testing of intercontinental ballistic missile technologies and has further increased tensions. These actions have elicited serious concerns, with new U.S. sanctions passed in February 2016 following additional punitive measures taken by Japan and South Korea.

North Korea has continued to test weapons systems since 2012, including the launch of the long-range Unha-3 rocket in December 2012 and a nuclear test in February 2013. Pyongyang threatened a fourth test in November 2014, following the adoption of a resolution by the UN General Assembly condemning North Korean human rights abuses.

Other incitements include firing rockets across the South Korean border, known as the Demilitarized Zone (DMZ), in August 2015 and North Korea’s cyberattack on U.S.-based Sony Pictures in December 2014, as well as its 2010 shelling of South Korea’s Yeonpyeong Island, which is located around twelve miles south of the North Korean coast.

MRI with nanoscale resolution

A new NMR microscope gives researchers an improved instrument to study fundamental physical processes. It also offers new possibilities for medical science, for example to better study proteins in Alzheimer patients’ brains.

This is a major step forward towards the ultimate goal of a device that can measure variations at the nanoscale to study the properties of the inhomogeneous electron systems which are at the forefront of modern condensed-matter physics, such as the surface states of topological insulators, oxide interfaces and other strongly correlated electron systems including the high-Tc superconductors

If you get a knee injury, physicians use an MRI machine to look right through the skin and see what exactly is the problem. For this trick, doctors make use of the fact that our body’s atomic nuclei are electrically charged and spin around their axis. Just like small electromagnets they induce their own magnetic field. By placing the knee in a uniform magnetic field, the nuclei line up with their axis pointing in the same direction. The MRI machine then sends a specific type of radio waves through the knee, causing some axes to flip. After turning off this signal, those nuclei flip back after some time, under excitation of a small radio wave. Those waves give away the atoms’ location, and provide physicians with an accurate image of the knee.

NMR

MRI is the medical application of Nuclear Magnetic Resonance (NMR), which is based on the same principle and was invented by physicists to conduct fundamental research on materials. One of the things they study with NMR is the so-called relaxation time. This is the time scale at which the nuclei flip back and it gives a lot of information about a material’s properties.

The purple ball induces a uniform magnetic field, so that the surrounding atomic nuclei all line up with their axis pointing in the same direction. The researchers send radio waves through their sample, causing some nuclei to flip the other way, and measure how long it takes before they flip back again.

Spacex launching 30% more each launch and increasing launch frequency to once every two weeks

A successful launch Monday would give SpaceX seven completed missions this year, setting a new record for the company with still nearly half of the year remaining. Considering the company's launch manifest for the rest of 2016, it is possible the company will make 12 or more flights of its Falcon 9 rocket in 2016, and it may come close to reaching its stated goal of a launch cadence of once every other week by the end of 2016.

Spacex is increasing its launch rate while also making two substantial improvements to its Falcon 9 launch system. The first, recoverability, has gotten the most attention. SpaceX has now landed three of its Falcon 9 boosters on an autonomous drone ship and one on land. Another land-based try is forthcoming—about eight or nine minutes after Monday morning's launch, the first stage of the Falcon 9 will fly back to a landing zone near Cape Canaveral.

The second improvement, using super-cooled liquid rocket fuel, also represents a significant advance. In December 2015, the company debuted its Falcon 9 Full Thrust vehicle, an upgrade from the Falcon 9 v1.1 that included a number of improvements. Perhaps most notable was its use of supercooled liquid oxygen and kerosene fuels. Because colder liquids can be compressed, more of these fuels can be loaded into the Falcon 9's tank. Although it initially led to some difficulties during the fueling process and launch aborts, SpaceX appears to have mastered loading these colder fuels onto the rocket.

The result is a 30-percent gain in power and the ability to launch considerably more mass to low-Earth orbit—22.8 tons now compared to 13.2 with the older version of the rocket. This also means that if you're launching a payload that weighs less than that into space, you've got plenty of fuel left over to stick a first stage landing back on Earth.



The Lancet: Stroke is largely preventable, with hypertension confirmed as biggest risk factor, according to global study

Hypertension (high blood pressure) remains the single most important modifiable risk factor for stroke, and the impact of hypertension and nine other risk factors together account for 90% of all strokes, according to an analysis of nearly 27000 people from every continent in the world (INTERSTROKE), published in The Lancet.

Although the same ten risk factors were important, and together accounted for 90% of stroke risk in all regions, the relative role of some individual risk factors varied by region, which the authors say should influence the development of strategies for reducing stroke risk.

Stroke is a leading cause of death and disability, particularly in low-income and middle-income countries. The two major types of stroke include ischaemic stroke (caused by blood clots), which accounts for 85% of strokes, and haemorrhagic stroke (bleeding in the brain), which accounts for 15% of strokes. Prevention of stroke is a major public health priority, but needs to be based on a clear understanding of the key preventable causes of stroke.



Turkish President Erdogan Returns to Istanbul Amid Coup Attempt; 60 Killed, 336 Arrested

A coup was attempted in Turkey Friday with a faction of the military taking over state TV, imposing martial law and a curfew and reportedly attacking the police headquarters in the capital of Ankara, according to American and foreign officials.

"The situation unfolded in Turkey was a coup attempt to overthrow the democratically-elected government," read a statement released by the Turkish embassy in Washington, D.C., late Friday night. "This attempt was foiled by the Turkish people in unity and solidarity. Our President and Government are in charge. Turkish Armed Forces was not involved in the coup attempt in its entirety. It was conducted by a clique within the Armed Forces and received a well-deserved response from our nation."



World's cheapest smartphone is $3.67

An Indian company has launched what is being billed as the world's cheapest smartphone.

Ringing Bells said their Freedom 251 phone would cost just 251 rupees ($3.67; £2.56), and there was huge demand in the first hours of sale.

But sceptics have raised questions about the device and the company's price strategy.

India is the world's second-largest mobile market and has one billion mobile phone subscribers.

Freedom 251 is expected to target a market already dominated by low-cost handsets.

The Freedom 251 smartphone resembles Apple's iPhone 4

Moscow Starts Developing Heavy Engine for Joint Chinese-Russian Airliner

Russia has informed China about the beginning of the development of a heavy aircraft engine with a thrust of 35 tons for the Sino-Russian long-range wide-body aircraft. Russian Deputy Prime Minister Dmitry Rogozin told reporters on Monday after a meeting of the Russian-Chinese intergovernmental commission on the preparation of regular meetings of the heads of government that this is the key point of the project for the development of a joint airliner.

"In addition, we informed the Chinese side of the beginning of the work on Russia’s heavy aircraft engine in the thrust segment up to 35 tons, the decision on creating which was made by the Russian president recently - in May, and the necessary funds were allocated", he said. "This almost solves the problem associated with the creation of a long-range wide-body aircraft, because the plane is impossible without an engine", Rogozin added.

The parties have agreed that Russian and Chinese aviation companies would first of all determine the operational life of the aircraft currently used on the leading air routes.

Russia’s United Aircraft Corporation (UAC) and Commercial Aircraft Corporation of China Ltd (COMAC) began in early 2015 preliminary design of their proposed joint 250-280-seat wide-body airliner, which Moscow now expects to enter service in 2025.

The engine will be among the most powerful in the world, more powerful than that used on Boeing 787-10 with 340 KN thrust. Russia will be in charge of building the engines while China, the body of the airliner. Russia will build an engine plant for the airliner while the airliner will be assembled in China.

The airliner will be developed on the basis of Russia’s Il-96 airliner, which is quite reliable as it is used as Putin’s presidential aircraft. However, Il-96 is much smaller than the airliner that Russia and China have been jointly developing. It uses 4 engines while the airliner will only use two engines with much higher fuel efficiency.

Production of first prototype will be completed in 2023



OVC Cancer Breakthrough Leads to Human Clinical Trials

Cancer treatment in people could be transformed thanks to a study on treating cancer in animals led by researchers from the Ontario Veterinary College (OVC) at the University of Guelph.

Their findings in mice and companion animals such as cats, published in the Journal of Immunology, are already leading to clinical trials to treat people with various forms of cancer.

Nottingham, Uppsala and GE researchers have a new breakthrough method for large scale production of stem cells

Scientists have discovered a new method of creating human stem cells which could solve the big problem of the large-scale production needed to fully realise the potential of these remarkable cells for understanding and treating disease.

The discovery has been made by a team of scientists at The University of Nottingham, Uppsala University and GE Healthcare in Sweden.

Human pluripotent stem cells are undifferentiated cells which have the unique potential to develop into all the different types of cells in the body. With applications in disease modelling, drug screening, regenerative medicine and tissue engineering, there is already an enormous demand for these cells, which will only grow as their use in the clinic and by the pharmaceutical industry increases.

Reports of a successful military coup in Turkey

An attempted coup is being staged in Turkey as the military claims it has seized control of the country.

In the last hour gunfire was reported in the Turkish capital Ankara as military jets were seen flying overhead.

At the same time it has been reported that Istanbul's Bosphorus Bridge and Fatih Sultan Mehmet Bridge have been closed.

Prime Minister Binali Yildirim said those responsible for what he described as an attempted coup by a faction within the military would pay the highest price.

He says they would not be allowed to do anything to interrupt democracy

Washington Post and all other news sources are tracking the coup


The Turkish military has launched a coup against the government of President Recep Tayyip Erdogan, Turkish officials and the country's armed forces said Friday, in a stunning move that could plunge Turkey into further turmoil.

CNN Turk, the network's Turkish-language channel, reported Friday that soldiers had deployed to Istanbul's Ataturk Airport and that all flights had been cancelled.

US Navy envisions submarines with drones attaching and detaching like Remoras to sharks

The United States Navy would like to develop two key features for its next-generation SSN(X) successor to the Virginia-class attack submarines. One feature would effectively turn the future attack submarine into a underwater mother-ship for unmanned underwater vehicles (UUV) while another would dispense with noise-generating moving parts such as a propulsor or driveshaft in the propulsion system.

Vision of drones on a mother ship submarine like remoras

“I would like some organic means of designing the submarine from the ground up that would seamlessly integrate UUVs,” Rear Adm. Michael Jabaley, the Navy’s program executive officer for submarines told the House Armed Services Committee on July 14.




Such a feat is still a technological leap. However, it would be a vast improvement on the current system of using every opening on a submarine to deploy a UUV. The Navy’s undersea force uses everything from torpedo tubes to the submarines’ trash chute to launch UUVs. A system such as the one Jabaley envisions would allow a future attack submarine to launch and recover UUVs at will.

US launches $400 million advanced wireless initiative and new spectrum policy

The US has launched a $400 million Advanced Wireless Research Initiative led by the National Science Foundation (NSF).

The new program will enable the deployment and use of four city-scale testing platforms for advanced wireless research over the next decade and builds upon the Federal Communications Commission’s (FCC) Spectrum Frontiers vote yesterday.

It will make vast quantities of high-frequency millimeter wave spectrum available for both licensed and unlicensed use. This spectrum, in combination with other spectrum already available, promises to enable faster speeds, quicker response times (“lower latency”), and increased capacity in future wireless networks.

The spectrum policy and research efforts will accelerate the deployment of a new generation of wireless networks that are up to 100 times faster than today. These super-fast, ultra-low latency, high-capacity networks will enable breakthrough applications for consumers, smart cities, and the Internet of Things that cannot even be imagined today. Possible advances in the next decade could bring:

  • Mobile phones and tablets that can download full length HD movies in less than 5 seconds, 100 times faster than 4G (6 minutes) and 25,000 times faster than 3G (26 hours).
  • First responders and emergency room doctors who get live, real-time video and sensor data from police vehicles, ambulances, and drones, along with patient vitals and medical records—all before the patient arrives at the hospital door.
  • Semi- or fully-autonomous vehicles that can communicate with the outside world and with each other to improve travel efficiency and safety.
  • Factories equipped with always-connected smart manufacturing equipment that self-diagnose and repair themselves before they break.
  • Gigabit-speed wireless broadband available in businesses, public transportation stations, stadiums, campuses, schools, malls, parks, and other public spaces.
  • Virtual reality training environments and simulators that allow entry-level workers to develop and demonstrate skills in high-demand fields like solar energy installation—anytime, from anywhere.



The initiative includes an $85 million investment in advanced wireless testing platforms that comes from the NSF and more than 20 technology companies, including Samsung, Intel and Verizon. The foundation also said that it will invest an additional $350 million over the next 7 years in academic research to test these platforms.

Chinese researchers have an improved aircraft engine alloy

China’s news.ifeng.com is hailing a new alloy as being a success in China's program 973 an aircraft engine project. Chen was funded at Nanjing Polytechnic University and the state’s Program 973.

It seems that the new alloy will allow an engine built with it to operate at 150-200 degrees celsius higher temperature.

Inferior engine alloys have been a primary gap in China's aviation technology. Even catching up with US jet engine materials would be a major development for China's commercial and military jet efforts.

Nature Materials - Polysynthetic twinned TiAl single crystals for high-temperature applications





Optical micrographs of directionally solidified Ti–45Al–8Nb PST single crystals at different withdrawal rate

General Electric development of the Titanium alloy Ti-48Al-2Cr-2Nb (Alloy 4822) as a critical technology for the GEnx engine used in the Boeing 787. alloy 4822 was hailed as a success in the development of aircraft engine materials as it reduces the weight of an aircraft engine by 200 pounds, fuel consumption by 20% and discharge of NOx by 80% and significantly lowered engine noise.

Abstract - Nature Materials - Polysynthetic twinned TiAl single crystals for high-temperature applications

TiAl alloys are lightweight, show decent corrosion resistance and have good mechanical properties at elevated temperatures, making them appealing for high-temperature applications. However, polysynthetic twinned TiAl single crystals fabricated by crystal-seeding methods face substantial challenges, and their service temperatures cannot be raised further. Here we report that Ti–45Al–8Nb single crystals with controlled lamellar orientations can be fabricated by directional solidification without the use of complex seeding methods. Samples with 0° lamellar orientation exhibit an average room temperature tensile ductility of 6.9% and a yield strength of 708 MPa, with a failure strength of 978 MPa due to the formation of extensive nanotwins during plastic deformation. At 900 °C yield strength remains high at 637 MPa, with 8.1% ductility and superior creep resistance. Thus, this TiAl single-crystal alloy could provide expanded opportunities for higher-temperature applications, such as in aeronautics and aerospace.

At least 100 million muslims have a favorable view of ISIS and over 200 million support terrorism as a tactic

Pew Research Center surveyed muslim countries to determine how much support there is for terrorism, strict sharia law and other questions. There are over 1.7 billion muslims in the world.

Countries with the most muslims have large and growing populations.

Pakistan's estimated population in 2016 of about 197 million and is growing by about 5 million every year.
Nigeria has an estimated 2016 population of about 187 million and is growing by about 5 million every year.
Indonesia's estimated population in 2016 of about 260 million and is growing by about 3 million every year.
Turkey's estimated population in 2016 of about 80 million and is growing by about 1.2 million every year.
Malaysia's estimated population in 2016 of about 30.7 million and is growing by about 0.5 million every year.


How many support the terrorist group ISIS ?

Only 28% in Pakistan had an unfavorable view of ISIS, and a majority of Pakistanis (62%) had no opinion on the extremist group.

9% of Pakistan support [have a favorable view of] ISIS which is 17.8 million and another 122 million had no opinion or would not say it.


14% of Nigeria supports [have a favorable view of] ISIS which is 26.2 million and another 37.4 million had no opinion or would not say it.

Another 21 million supports [have a favorable view of] ISIS in Indonesia, Turkey, Malaysia and Senegal with another 75 million had no opinion or would not say it.

Lower population places like Palestine also support ISIS and clearly there is support in Syria, Iraq, Egypt, Iran, Libya and Afghanistan.

So at least 100 million muslims support [have a favorable view] ISIS and if say around half of those who would not say their opinion had some support then it could be another 200-300 million.

A favorable view of terrorism as a tactic in general is even higher than support for ISIS About 200 million muslims support terrorism as a tactic.

Support of Sharia law and the death for conversion from Islam part of sharia

Strict Sharia law support is around 700 million to 1 billion.
Support for the death for leaving Islam is about 500-700 million.





How many in the USA

Pew Research Center estimates that there were about 3.3 million Muslims of all ages living in the United States in 2015. This means that Muslims made up about 1% of the total U.S. population (about 322 million people in 2015), and we estimate that that share will double by 2050.


Nanoparticles create invisibility at a greater range of frequencies which will allow antennas in more shapes, sizes and materials

Scientists at Queen Mary University of London (QMUL) have made an object disappear by using a composite material with nano-size particles that can enhance specific properties on the object's surface.

Researchers from QMUL's School of Electronic Engineering and Computer Science, worked with UK industry to demonstrate for the first time a practical cloaking device that allows curved surfaces to appear flat to electromagnetic waves.

While the research might not lead to the invisibility cloak made famous in J.K Rowling's Harry Potter novels quite yet, this practical demonstration could result in a step-change in how antennas are tethered to their platform. It could allow for antennas in different shapes and sizes to be attached in awkward places and a wide variety of materials.

Co-author, Professor Yang Hao from QMUL's School of Electronic Engineering and Computer Science, said: "The design is based upon transformation optics, a concept behind the idea of the invisibility cloak.

IBM and Samsung have fast STT-MRAM which could replace flash memory

IBM colleagues and Samsung have published a paper demonstrating switching MRAM cells for devices with diameters ranging from 50 down to 11 nanometers in only 10 nanoseconds, using only 7.5 microamperes.

“With PMA we are capable of delivering good STT-MRAM performance down to 7×10^-10 write-error-rate with 10 nanosecond pulses using switching currents of only 7.5 microampere. This could never be done with in-plane magnetized devices — they just don’t scale. While more research needs to be done, this should give the industry the confidence it needs to move forward. The time for Spin Torque MRAM is now,” said Worledge.

STT-MRAM is 100,000 times faster than NAND flash and never wears out.

It falls into a performance sweet spot compared to other memory technologies and this level makes it viable to manufacture.

Spin-torque MRAM can be used for a new type of working memory in ultra-low power applications. For example, it can be used in IoT or mobile devices, where it uses very low power when it's on and storing information, and when it's not actively being used, it uses zero power because it's not volatile.

Worledge said he doesn't believe that IBM's STT MRAM will replace DRAM anytime soon, but he said it can easily replace embedded flash, since MRAM is easier to embed, is faster and has unlimited reads and writes.

Abstract

The dependence of the write-error rate (WER) on the applied write voltage, write pulse width, and device size was examined in individual devices of a spin-transfer torque (STT) magnetic random-access memory (MRAM) 4 kbit chip. We present 10 ns switching data at the 10-6 error level for 655 devices, ranging in diameter from 50 nm to 11 nm, to make a statistically significant demonstration that a specific magnetic tunnel junction stack with perpendicular magnetic anisotropy is capable of delivering good write performance in junction diameters range from 50 to 11 nm. Furthermore, write-error-rate data on one 11 nm device down to an error rate of 7×10-10 was demonstrated at 10 ns with a write current of 7.5 μA, corresponding to a record low switching energy below 100 fJ.

Blackhawk helicopter replacements will have twice the speed and range and will have first flights in 2017

The Bell V-280 Valor and the Boeing SB1 Defiant are being developed as replacementsf or the Blackhawk helicopter.

The Bell V-280 Valor is a third-generation tilt-rotor concept being developed by Bell Helicopter and Lockheed Martinfor the United States Army's Future Vertical Lift (FVL) program. Bell and Lockheed claim an AV-280 variant can launch rockets, missiles, and even small unmanned aerial vehicles forward or aft with no rotor interference, even in forward flight and cruise modes with the rotors forward.



Sikorsky Aircraft and Boeing are jointly producing a medium-lift-sized demonstrator they call SB-1 Defiant for phase one of the program. It is to fly in 2017 and will be evaluated by the Army for further development. Sikorsky is leading the development of phase one with an aircraft based on their previous Sikorsky X2 design


The V-280 is reported to be designed for a cruising speed of 280 knots (320 mph; 520 km/h) a top speed of 300 knots (350 mph; 560 km/h), a range of 2,100 nautical miles (2,400 mi; 3,900 km), and an effective combat range of 500 to 800 nmi (580 to 920 mi; 930 to 1,480 km)



The Blackhawk has a maximum speed of 183 mph (cruising speed of 170 mph) and a combat radius of 368 miles.

China on track to 12 operational J-20 stealth fighters in 2017 for airpower edge over other countries in Asia

In July 2016, the Chengdu Aircraft Corporation rolled out two more low rate initial production (LRIP) J-20 stealth fighters. This brings to a total of four J-20 fighters built for service into the Chinese air force, as opposed to the original eight J-20 prototypes, which are still undergoing a rigorous flight testing regimen. At this rate of production, China may have 12 production J-20 ready to hand off to a PLAAF squadron for operational and flight familiarization, with an initial operating capability (IOC -- meaning those fighters can conduct combat operations) in 2017-2018.

If the J-20 meets its 2017-2018 IOC target date, it will give China a technological edge in air to air combat over all its Asian neighbors, who do not yet have 5th generation planes. As a heavyweight stealth fighter, it is armed with long range missiles, electronic warfare, advanced radar and passive sensors, making it a respectable competitor to even the new US F-22 and F-35 stealth fighters. CAC is already planning a series of future updates to keep the J-20 state of art; domestic WS-15 engines are just one of them.


The J-20 will be stealthy, fast, heavily armed with long range air to air missiles, and state of the art radar and infrared sensors. Perhaps more than any other weapon, the J-20 represents China's military modernization. via China Defense Forum
