Chinese scientists now send a hackproof Snapchat like ‘Self Destruct’ code from Space to Earth using Quantum Satellite

China successfully Teleports Object from Earth to Space

Chinese quantum satellite sends ‘unbreakable’ code which will self-destruct if hacked or tampered

Always trust the Chinese to do the unthinkable. They have come a long way from reverse-engineering products made in United States, Japan, and South Korea to build their own hack proof quantum satellite. Even in light of people making jokes about Chinese products being third class, their scientists are toiling hard to make new breakthroughs in teleportation tech which we had reported earlier. Now the Chinese scientists have made a new record by using their quantum satellite to send an unbreakable hack-proof code which will self-destruct if it is accessed by an unauthorized person or is tampered with.

Most people associate self-destruct tech with Snapchat so it would be right to call that Chinese scientists have managed to send “unbreakable” Snapchat code from a satellite to the Earth which will self-destruct in case if it is accessed by an unauthorized person or tampered with. China was the first country to teleport a ‘Photon’ 500 km into space like we used to see in the Star Trek movies and in the Star Trek TV show. Now Chinese have created another record by marking the first time space-to-ground quantum key distribution technology.

The teleportation and now the unbreakable code were sent using world’s first quantum satellite that China launched last August, to help establish “hack proof” communications, a development the Pentagon has called a “notable advance”.

The satellite sent totally hack-proof quantum keys to ground stations in China between 645 km (400 miles) and 1,200 km (745 miles) away at a transmission rate up to 20 orders of magnitude more efficient than an optical fibre, Xinhua cited Pan Jianwei, lead scientist on the experiment from the state-run Chinese Academy of Sciences, as saying. “That, for instance, can meet the demand of making an absolute safe phone call or transmitting a large amount of bank data,” Pan said.

“That, for instance, can meet the demand of making an absolute safe phone call or transmitting a large amount of bank data,” Pan said.

What makes Chinese scientists attempt to send the unbreakable code from space to Earth is its self-destruct feature. Any attempt to eavesdrop on the quantum channel would introduce detectable disturbances to the system and make it destroy itself. “Once intercepted or measured, the quantum state of the key will change, and the information being intercepted will self-destruct,” Xinhua said.

The above news has to be taken with a pinch of salt as no other scientists from the world fraternity have confirmed it. China still lags behind the United States, India, and Russia in space technology though China is attempting to close in on the difference.

This has been published in the journal Nature on Thursday.

Israeli MedTech Company Wants To Stop Hospitals From Making You Sicker

Israeli MedTech Company Wants To Stop Hospitals From Making You Sicker

Israeli MedTech Company Wants To Stop Hospitals From Making You Sicker

Exploring New Ways Tech Can Significantly Change Hospital Procedures And Patient Care

My mom always told me I should really think twice before going to the hospital, as there’s a good chance I will leave sicker than when I arrived. It turns out it’s not just an old wives tale, and that there are actual risks involved with hospital visits and routine procedures. Here’s one Israeli MedTech company, ART MEDICAL, that’s doing something about this.

Patient Vulnerability In Hospitals Today

According to ART MEDICAL, a very common type of hospital acquired illness is pneumonia. Patients who are intubated sometimes have excess saliva and acid reflux that cause specific types of respiratory infections and illnesses. Currently, the only way to avoid these types of conditions is for personnel in Intensive Care Units to constantly physically monitor the status of the patient as most of these infections occur in ICUs. This cumbersome process results in a high error rate, due to the busy nature of the ICU and the inability to detect abnormal reactions as they begin to develop. These aren’t just inconveniences, rather situations that actually cause fatalities in the ICU.

Advanced Technology That’s Transforming The Medical Industry

Meet ART MEDICAL and its smart enteral feeding system. This company’s wide array of sensors and smart devices can give a warning as to what needs to be done in order to avoid fatal situations and sometimes automate them altogether. ART MEDICAL claims that this platform will save lives, as fewer people will be afflicted by hospital acquired pneumonia.

Smart devices are no new feature in medicine, with everything from fitness trackers to smart surgery robots being used today. Even still, ART MEDICAL claims they are the first to integrate this type of unique technology into the enteral feeding industry. Another interesting feature of the product is the event log, acting as a live interactive chart documenting all the feeding events a patient had and how long they were fed for, which could be a useful method to reduce bureaucracy and systematically track treatment. The system displays an interactive graphical representation of the feeding itself, making sure to give medical professionals as much information as possible in real time.

ART MEDICAL secured $20M in funding to further develop their allegedly life-saving technology, the funding round was led by Advanced Medical Technologies LLC, and is the second round received by the company, with the previous round being a $7M investment.

“One of the challenges for the ICU staff is patients’ prolonged length of stay and mortality from complications which are unrelated to the original reason for hospitalization,” says founder and CEO, Liron Elia. “Aspiration of foreign materials is a major risk for intubated patients and technology is what is needed to solve this problem. We are confident that ART MEDICAL has the solution.”

The jury is still out whether smart technology and automated services can truly replace real doctors and nurses in any capacity. Let’s not forget that, if something goes wrong, solely relying on a solution such as this can endanger more lives than it saves. However, ART MEDICAL’s technology is a helpful tool to supplement current manual procedures in hospitals.

US military reveals $65m ‘Matrix’ project to plug our brains directly into computers

US military reveals $65m 'Matrix' project to plug our brains directly into computers

DARPA Is Spending $65 Million To Research Brain-Computer Interfaces

The DARPA (Defense Advanced Research Projects Agency) on Monday awarded contracts to five organizations and one company to develop neural implants that can enable communication between the brain and digital systems. The funding to the tune of $65 million comes under the agency’s Neural Engineering System Design (NESD) programme launched last year under the Obama administration’s BRAIN Initiative that aims to research and develop a high-resolution neural interface.

Paradromics, Inc, a company out of San Jose and Brown University will focus on aspects of hearing and speech, while Columbia University, Fondation Voir et Entendre (The Seeing and Hearing Foundation) in Paris, France, John B. Pierce Laboratory in Connecticut and the University of California, Berkeley, will study vision.

NESD is looking to design an “implantable system able to provide precision communication between the brain and the digital world. Such an interface would convert the electrochemical signaling used by neurons in the brain into the ones and zeros that constitute the language of information technology, and do so at far greater scale than is currently possible,” the agency said in a statement on Monday.

The outcome of the research is expected to help those with disabilities such as hearing, vision, and speech. “The work has the potential to significantly advance scientists’ understanding of the neural underpinnings of vision, hearing, and speech and could eventually lead to new treatments for people living with sensory deficits,” the agency added.

“The NESD program looks ahead to a future in which advanced neural devices offer improved fidelity, resolution, and precision sensory interface for therapeutic applications,” said Phillip Alvelda, the founding NESD Program Manager. “By increasing the capacity of advanced neural interfaces to engage more than one million neurons in parallel, NESD aims to enable rich two-way communication with the brain at a scale that will help deepen our understanding of that organ’s underlying biology, complexity, and function.”

The research will be divided into two phases. The program’s first year will focus on hardware, software and neuroscience, including testing on animals and cells. On the other hand, phase two will include further study, progress in miniaturization and integration of the neural technology, with attention to future regulatory approval. As part of that phase, the agency and its partners will coordinate with the Food and Drug Administration (FDA) to explore issues such as long-term safety of installing DARPA’s dream implant in and on the human brain, privacy, information security and compatibility with other devices.

DARPA is hoping to have prototypes of devices that can communicate information between the brain and computers ready at the end of the four-year program, although the chances of these being used in a clinical or commercial sense within that timeframe is not likely possible.

China successfully Teleports Photon 500 Km Into Space

China successfully Teleports Object from Earth to Space

Star Trek-like teleportation possible as China teleports ‘Photon’ 500 Km into space

If you are a fan of Gene Roddenberry’s Star Trek, you will know what I am talking about. Gene’s Star Trek first showed the world what teleportation was all about by beaming Captain Kirk, Spock, Bones and others from one place to another. What seemed like a sci-fi thing in Star Trek may soon become a reality and in this march to teleportation, China has stolen the glory.

Chinese scientists successfully “teleported” data from one elementary particle to another. In plain English, the Chinese researchers have teleported a ‘Photon’ from China roughly 500 km into space. China, which already has a quantum computer and hack-proof communications satellite, now has a significant edge over the United States and Japan in developing unbreakable codes in the cutting edge field of quantum cryptography.

Teleportation

Last year, China had successfully launched the world’s first quantum-enabled satellite called Micius / Mozi, which is also called hack-proof satellite.
“Micius / Mozi” named after an ancient Chinese philosopher who died in 391 B.C. The rocket placed Micius in a Sun-synchronous orbit so that it passes over the same point on Earth at the same time each day. While being a hack-proof communications satellite, Micius is also has a high power photon receiver that can detect the quantum states of single photons fired from the ground. That’s important because it should allow scientists to test the technological building blocks for various quantum feats such as entanglement, cryptography, and teleportation.
Chinese scientists started experimenting Micius’  Photon Receiver capability to physically teleport elementary particles from Earth. This is a breakthrough of sorts for physicists around the world because it would let them teleportation which would finally help humans in space.
On 10th July , the Micius reaserch team announced the results of its first experiments. The team created the first satellite-to-ground quantum network, in the process smashing the record for the longest distance over which entanglement has been measured. And they’ve used this quantum network to teleport the first elementary particle from the Earth station into orbit.

What is teleportation?

In layman English, teleportation means sending a person or an object from one place to another without physically changing shape. In more serious terms, Teleportation or teletransportation is the theoretical transfer of matter or energy from one point to another without traversing the physical space between them. While it was easy for filmmakers to portray teleportation in their movies, physically it was though impossible feat till a few years ago. Teleportation has become a standard operation in quantum optics labs around the world. The technique relies on the strange phenomenon of entanglement. This occurs when two quantum objects, such as photons form at the same instant and point in space and so share the same existence. In technical terms, they are described by the same wave function.

Is Teleportation possible? YES,Chinese researchers have Teleport "Photon" 500 kms above Earth.

Chinese teleportation

As soon as Micius was launched, the Chinese researchers went about to achieve particle teleportation. The Chinese team created entangled pairs of photons on the ground at a rate of about 4,000 per second. They then beamed one of these photons to Micius, which passes over China every day at midnight. They kept the other photon on the ground.
Finally, they measured the photons on the ground and in orbit to confirm that entanglement was taking place and that they were able to teleport photons in this way. Over 32 days, they sent millions of photons and found positive results in 911 cases.
As you can see from their success ration, human teleportation is still a far way off but this is a big scientific breakthrough nonetheless.  “We report the first quantum teleportation of independent single-photon qubits from a ground observatory to a low Earth orbit satellite through an up link channel with a distance up to 1400 km,” says the Chinese team.
Teleportation through which Scotty beamed Kirk and Spock in space in Star Trek, is no more a fiction but a reality now. The Photon disappeared from Earth and appeared in space, a thing which was unimaginable till a few years ago.

Indian Teen Develops World’s ‘Smallest’ Satellite- And NASA Is Launching It

18 Year Old Indian Teen Develops World’s ‘Smallest' Satellite- And NASA Is Launching It

NASA to launch 18-year-old Indian teen’s world smallest satellite on June 21

Of late, India has seen a lot of child prodigies emerging from its country. Be it Akrit Jaswal, the boy who performed his first surgery at the age of 7 or Kishan Shrikanth, recognized as the youngest director in the world by Guinness Book of World Records or Kautilya Pandit, an 8-year-old wonderkid with extraordinary memory, named as India’s “Google boy”.

This time around it is an 18-year-old boy, Rifath Sharook from Pallapatti town in Tamilnadu, India who has designed ‘KalamSat’, which is claimed to be the lightest and smallest satellite in the world for NASA.

Weighing just 64 grams, ‘KalamSat’, which is named after India’s nuclear scientist and former President, APJ Abdul Kalam, will be launched by on an SR-4 rocket from Wallops Space Flight facility at Virginia, U.S. on June 21. This is the first time ever that NASA would be conducting an Indian student’s experiment for its sub-orbital space flight.

So, how did Sharook’s experiment get through NASA? Sharook’s project, which is a first to be manufactured via 3D printing got selected through a contest, ‘Cubes in Space’, sponsored jointly by NASA and ‘I Doodle Learning’ organization.

Sharook said that the satellite is made of reinforced carbon fibre polymer. The mission phase of the space launch will be 240 minutes, during which the satellite will operate for 12 minutes in a micro-gravity environment of space before it begins its downward route back towards the ocean. The aim of the project is to provide motivation to plan economical space missions in future.

“The main role of the satellite will be to demonstrate the performance of 3-D printed carbon fibre,” Sharook was quoted as saying by the Times of India (TOI).

The main challenge of the contest was to create an experiment that would fit into a four-metre cube and weight exactly 64 grams so that it can be flown to space.

He said, “We did a lot of research on different cube satellites all over the world and found ours was the lightest.”

Talking about his experience, Sharook said, “We designed it completely from scratch. It will have a new kind of onboard computer and eight indigenous built-in sensors to measure acceleration, rotation and the magnetosphere of the earth. We obtained some of the components from abroad and some are indigenous.”

As the satellite weighs less than 0.1 kg, it has fallen in the category of ‘femto’ group.

The Cubes in Space contest, in which Sharook’s lightweight satellite emerged as the winner in the Space Kidz India program, inspires students to design an experiment that could be sent to space.

“Our goal is to help kids from around the world learn to problem-solve, to get them inspired about learning, to learn skills and develop interests that will prepare them to succeed in the future,” its organizers say.

This is not the first time Sharook has invented something unique. In 2015, he had launched a 1,200g helium weather balloon into the atmosphere.

China To Send People To Catch Live Asteroids To Mine And Live there

China To Send People To Catch Live Asteroids To Mine And Live there

China hatches plans to catch an asteroid

After becoming the world’s second biggest economy and creating probably the biggest trading network, China is now planning to up their game to the next frontier – literally. China is now hatching plans to catch an asteroid and mine it for precious materials that asteroids have been rumored to contain.

Mission being planned

China is developing plans to find, catch, land and then mine an asteroid within the near future. The hopes for this plan is to mine the asteroid for many special materials that asteroid have been rumored to contain . For instance, uranium that is rare to find is large quantities on earth  – the reason being the element was deposited on earth by asteroid that hit our planet in its early years. Having an asteroid to supply such elements can give an incalculable boost to nuclear energy and the country’s economy. This alone, should give you a clear indication of the country’s motivation.

Chinese Space Program

The chief commander and designer of China’s lunar exploration program Ye Peijian told state media that the country plans to launch its first space craft within the next 3 years. The big picture of the space mission, is to includes using asteroids as a base for the eventual Chinese Space Station. This reveal however, is just the latest in the big space ambitions of the Chinese including plans to build a lunar base in collaboration with the European Space Agency.

The first stage of the mission would be to land a spacecraft on the asteroid and then using rockets to change its trajectory. If this succeeds, the asteroid could then be moved into the moon’s orbit thus, making the next step of mining the asteroid feasible. Just like similar plans announced by NASA – the Chinese are hopeful that the value of the elements mined from the asteroid will negate the cost of the mission. NASA is hopeful of traveling to an asteroid in the early 2020s, with two missions called Lucy and Psyche.

Adding credibility to these ambitious plans is the interest generated by private entities in the trillions of dollars that asteroids are expected to contain.  In 2015, Barack Obama made it legal for private citizens to own celestial bodies – opening up the ability to for people to buy and own their asteroids.

Time machine model developed proves that time travel is mathematically possible

Time machine model developed proves that time travel is mathematically possible

Time Travel Is Mathematically Possible, Say Researchers

Time travel has always created curiosity among people and much so for scientists who have been working over the years to solve or refute the theory. In fact at some point of time in our lives, the thought of travelling to a different time would have flashed through our minds too. And if mathematicians from the University of British Columbia and the University of Maryland are to be believed, then this dream of ours might have just got wings that’s at least for now.

According to the paper titled “Traversable acausal retrograde domains in spacetime (TARDIS)” that published in IOPScience Classical and Quantum Gravity journal recently, experts have developed a mathematical model of a ‘time machine’ that could manipulate the space-time continuum enough to travel backwards through time.

“People think of time travel as something as fiction,” says study author, theoretical physicist and mathematician, Ben Tippett from the University of British Columbia. “And we tend to think it’s not possible because we don’t actually do it. But, mathematically, it is possible.”

Mr Tippet along with his co-author and astrophysicist David Tsang from University of Maryland describe the TARDIS machine as a ”bubble” of space-time geometry that carries whatever’s inside it backward and forward through space and time along a circular path through spacetime.

Mr Tippett and Mr Tsang have used Einstein’s theory of general relativity to come up with their mathematical model ‘TARDIS’ in order to prove the theoretical possibility of time travel. In other words, the idea is that an object can travel through time if it reaches the speed of light.

In general relativity, curvature of space-time account for the curved orbits of the planets. If space-time was not curved, planets and stars would move in straight lines. So, space-time geometry becomes curved near a massive star, which in turn makes the straight trajectories of nearby planets to bend to follow the curvature around the star.

“The time direction of space-time surface also shows curvature,” Mr Tippett says.

“There is evidence showing the closer to a black hole we get, time moves slower. My model of a time machine uses the curved space-time – to bend time into a circle for the passengers, not in a straight line.

“That circle takes us back in time.”

So, if space-time is curved, and we run time along it at the same time, then theoretically the bend can be turned into a loop, making time travel possible.

“Since the 1950s, there have been many other proposals for space times which allow people to travel backward in time,” Mr Tippett says. “My work was to model a ‘time machine,’ where passengers inside of a box of limited size could travel along a circle through space and time, returning to their own pasts.

“The shape of spacetime was used to turn the direction of the arrow of time inside of the box in space and time. I then used Einstein’s theory to analyze this strange spacetime, and determine what would be required to build such a thing.

However, while time travelling is possible – at least in theory, Mr Tippett believes that scientists have yet to discover the right materials to bring a time machine to life and doubts that anyone will ever be able to build a machine to make it work.

“HG Wells popularised the term ‘time machine’ and he left people with the thought that an explorer would need a ‘machine or special box’ to actually accomplish time travel,” Mr Tippett said.

“While is it mathematically feasible, it is not yet possible to build a space-time machine because we need materials — which we call exotic matter — to bend space-time in these impossible ways, but they have yet to be discovered,” he added.

Scientists in Germany fire up the world’s largest artificial sun

Scientists in Germany fire up the world's largest artificial sun

Germany Powers Up The World’s Largest “Artificial Sun”

Germany is one of the few countries that has majorly contributed to science and technology be it physics and chemistry to cars and consumer products. While Germany may be a world leader in innovation, boasting leading universities and research institutes alongside major engineering, IT and manufacturing industries, it isn’t exactly known for its year-round sunshine.

As a result, solar panels line Germany’s residential rooftops and top its low-slung barns. Also, more than twenty-two percent of Germany’s power is generated with renewables, of which close to quarter of that is provided by solar.

Now, German scientists are testing what they term as “the world’s largest artificial sun,” which they hope can make way for producing hydrogen to use as a green fuel in the future.

“Synlight” – a three storey electrically powered sun-lamp – constructed by the German Space Center (DLR) is being tested in Julich, a town located 30 kilometers (19 miles) west of Cologne. The Synlight experiment uses 149 xenon short-arc lamps normally found in cinemas to recreate the light from the Sun onto a single point, vaporizing water and producing hydrogen and oxygen. Each lamp claims producing roughly 4,000 times the wattage of the average light bulb. When this artificial sun is switched on, it produces an equivalent of 10,000 times the amount of solar radiation as intense as natural sunlight on Earth.

When all the lamps are swiveled to concentrate light on a single spot, the instrument can generate temperatures of around 3,500 degrees Celsius, which is around two to three times the temperature of a blast furnace.

“If you went in the room when it was switched on, you’d burn directly,” said Prof Bernard Hoffschmidt, a research director at the DLR.

According to DLR, these extremely high temperatures are necessary to carry out research on processes that use the Sun to produce solar fuels like hydrogen. Although hydrogen is considered by many as the green fuel of the future, as it produces no carbon emissions, producing it requires huge amounts of energy, which generally comes from burning fossil fuels.

Synlight itself consumes a large amount of energy. However, Hoffschmidt said that “In four hours the system uses about as much electricity as a four-person household in a year. Our goal is to eventually use actual sunlight to make hydrogen, rather than artificial light.”

While the DLR researchers have already accomplished splitting water into hydrogen and oxygen using the Sun in the laboratory, however, it has a long way to go to be scaled up for commercial use.

“I think commercial use will only really be possible when societies and governments realize that we cannot burn any more fossil fuels,” Hoffschmidt said.

Robots could soon be built with human flesh

Robots could soon be built with human flesh

Scientists want to cover robots in muscle fibers and tissues so that resemble human beings

If all goes well, we could very soon see robots being made with human flesh. Before you freak out, the purpose of the robot-dress up is to help those people who need tissue transplants.

Two University of Oxford biomedical researchers, Pierre-Alexis Mouthuy and Professor Andrew Carr, writing in Science Robotics, argue that moving humanoid robots could help create muscle and tendon grafts that actually work.

The researchers pointed to existing robots, including the Eccerobot, a plastic machine with ‘human’ bones, tendons and skin, to explain how future bots will grow real tissue.

They said: “Over the past decade, exciting progress has been made in the development of humanoid robots. In particular, musculoskeletal humanoids (such as Kenshiro and Eccerobot) were developed to interact with humans in a safer and more natural way. They aim to closely replicate the detailed anatomy of the human musculoskeletal system including muscles, tendons, and bones. We suggest that musculoskeletal robots may assist in the growth of musculoskeletal tissue grafts for tissue transplant applications.”

Adding further, they said, “With their structures activated by artificial muscles, musculoskeletal humanoids have the ability to mimic more accurately the multiple degrees of freedom and the normal range of forces observed in human joints.

“As a result, it is not surprising that they offer new opportunities in science and medicine”.

Today, sheets of cells are grown in stagnant tanks, but these “fail to mimic the real mechanical environment for cells,” say the scientists.

As a result, these tissues are often too weak to be effective – especially for “bone-tendon-muscle grafts… because failure during healing often occurs at the interface between tissues”.

Instead, we need a robot with “structures, dimensions, and mechanics similar to those of the human body”.

As tissue grows on the robot, it would receive the same stresses as it would face on a real human, creating stronger and healthier tissue for harvesting.

“It is now both technically possible and scientifically pertinent to explore in greater detail the potential of humanoids as tools for regenerative medicine,” conclude the researchers.

What’s more this would be a step towards “biohybrid humanoids” – bots of the future whose human muscles, tendons, and skin can self-repair.

Creator of Lithium-ion batteries creates powerful new battery with 3X energy

Creator of Lithium-ion batteries creates powerful new battery with 3X energy

Scientists are trying to make a better, safer and longer-lasting battery

John B. Goodenough, the creator of lithium-ion batteries, has come up with an alternative to modern day batteries. The 94-year-old is currently working with a team of researchers from Cockrell School to create a battery that will work longer, charge faster and will be safer to use.

A team of engineers at the University of Austin, led by Goodenough, has developed the world’s first low-cost all-solid-state battery that holds three times more energy than Li-ion battery. The research has been published in the journal of Energy & Environmental Science.

The solid state battery is not only safe but also has a long cycle life, a high volumetric energy density and fast rates of charge and discharge.

In Li-ion battery, liquid electrolytes are used to transport the ions between positive and negative sides of the battery. If the charging occurs too quickly, there is a risk of short circuit that may cause an explosion. However, the solid state battery replaces the liquid electrolyte found in lithium-ion batteries with glass. By using glass, the chances of lithium-ion batteries forming metal strands inside the liquid separating layers is eliminated, which in turn prevents short circuits, battery expansion or explosions. It would also allow batteries to operate at both hotter and cooler temperatures than current models allow.

The all-solid-state battery can be used for gadgets like smartphones and even electric vehicles or stationary energy storage.

“Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today’s batteries,” Goodenough said.

This new battery tech would also replace lithium with sodium, which can easily be obtained from sea water, thereby reducing the cost of manufacturing battery even further.

Currently, the battery is still in the early stages of development and it is unclear whether it will be available for commercial production.
