Quantum Satellite Secures Communications

A Chinese quantum satellite has dispatched transmissions over a distance of 1,200 km (746 miles), a dozen times further than the previous record, a breakthrough in a technology that could be used to deliver secure messages, state media said on Friday.

China launched the world’s first quantum satellite last August, to help establish “hack proof” communications between space and the ground, state media said at the time.

The feat opens up “bright prospects” for quantum communications, said Pan Jianwei, the lead scientist of the Chinese team, Quantum Experiments at Space Scale (QUESS), according to the official Xinhua news agency.

The scientists exploited the phenomenon of quantum entanglement, in which a particle can affect a far-off twin instantly, somehow overcoming the long distance separating them, a situation termed “spooky action at a distance” by the Nobel-prize winning physicist Albert Einstein, Xinhua added.

The team had successfully distributed entangled photon pairs over 1,200 km, it said, outstripping the distance of up to 100 km (62 miles) at which entanglement had previously been achieved.

The technology so far is “the only way to establish secure keys between two distant locations on earth without relying on trustful relay,” Pan told Xinhua, referring to encrypted messages.

The new development “illustrates the possibility of a future global quantum communication network” the journal Science, which published the results of the Chinese team, said on its website.

Artificial Intelligence At The Hospital

Diagnosing cancer is a slow and laborious process. Here researchers at University Hospital Zurich painstakingly make up biopsy slides – up to 50 for each patient – for the pathologist to examine for signs of prostate cancer. A pathologist takes around an hour and a half per patient – a task IBMs Watson supercomputer is now doing in fractions of a second.

“If the pathologist becomes faster by using such a system I think it will pay off. Because my time is also worth something. If I sit here one and a half hours looking at slides, screening all these slides, instead of just signing out the two or three positive ones, and taking into account that there may be a .1 error rate, percent error rate. this will pay off, because I can do in one and a half hours at the end five patients,” says Dr. Peter Wild, University Hospital Zürich.

The hospital’s archive of biopsy images is being slowly fed into Watson – a process that will take years. But maybe one day pathologists won’t have to view slides through a microscope at all. Diagnosis is not the only area benefiting from AI. The technology is helping this University of Sheffield team design a new drug that could slow down the progress of motor neurone disease. A system built by British start-up BenevolentAI is identifying new areas for further exploration far faster than a person could ever hope to.

Benevolent basically uses their artificial intelligence system to scan the whole medical and biomedical literature. It’s not really easy for us to stay on top of millions of publications that come out every year. So they can interrogate that information, using artificial intelligence and come up with ideas for new drugs that might be used in a completely different disease, but may be applicable on motor neurone disease. So that’s the real benefit in their system, the kind of novel ideas that they come up with,” explains Dr. Richard Mead, Sitran, University of Sheffield. BenevolentAI has raised one hundred million dollars in investment to develop its AI system, and help revolutionise the pharmaceutical industry.

30 Billion Switches Onto The New IBM Nano-based Chip

IBM is clearly not buying into the idea that Moore’s Law is dead after it unveiled a tiny new transistor that could revolutionise the design, and size, of future devices. Along with Samsung and Globalfoundries, the tech firm has created a ‘breakthrough’ semiconducting unit made using stacks of nanosheets. The companies say they intend to use the transistors on new five nanometer (nm) chips that feature 30 billion switches on an area the size of a fingernail. When fully developed, the new chip will help with artificial intelligence, the Internet of Things, and cloud computing.

For business and society to meet the demands of cognitive and cloud computing in the coming years, advancement in semiconductor technology is essential,” said Arvind Krishna, senior vice president, Hybrid Cloud, and director, IBM Research.

IBM has been developing nanometer sheets for the past 10 years and combined stacks of these tiny sheets using a process called Extreme Ultraviolet (EUV) lithography to build the structure of the transistor.

Using EUV lithography, the width of the nanosheets can be adjusted continuously, all within a single manufacturing process or chip design,” IBM and the other firms said. This allows the transistors to be adjusted for the specific circuits they are to be used in.

Artificial Blowhole Generates Electricity From Ocean Waves

Renewable energy companies want to tap the potential of waves. It’s proved tough to commercialise. But Australian firm Wave Swell Energy thinks it’s turned the tide on wave energy. Its device harnesses wave power like an artificial blowhole.

The waves pass by and it causes the water level inside this artificial chamber, which is open underneath the water, to rise and fall and as it does so it compresses air, and then creates a partial vacuum as it’s falling and we use that motion to drive an air turbine,” says Tom Deniss, CEO of the company Wave Swell Energy.

The oscillating water column concept has been used before, but the Wave Swell model comes with a difference.  “We use uni-directional flow, in other hands, air-flow simply coming in one direction past the turbine, whereas all other attempts have used bidirectional flow. Independent tests found the model was at least twice as efficient as a conventional device. When fully constructed, the device will measure 20 metres by 20 metres, with the air turbine sitting above the water. It will operate off the coast of King Island – in Bass Strait – in May next year, adds Tom Deniss.  “The excellent wave climate there and the support of the local community meant that it was just an ideal location for us to use as a demonstration of the commercial viability of our technology.”
The company hopes to rival the cost of the cheapest global energy sources in five years….finally untapping the power of the ocean.

Farming in Brooklyn

Erik Groszyk used to spend all day at his desk working as an investment banker. Now he cultivates his own urban farm out of a 40-foot shipping container in a Brooklyn parking lot.

I just found myself not satisfied and kind of yearning for more,’ says Erik Groszyk.  The Harvard grad is one of 10 ‘entrepreneurial farmers,’ selected from a batch of 500 applicants, working with Square Roots, an indoor urban farming company launched in November that grows local food year-round in the heart of New York City. Now, six months into the program, Groszyk said his training in farming, artificial lighting, water chemistry and nutrient balance allows him to harvest roughly 15 to 20 pounds of produce each week.

People have lost trust in the food system, right? They want real food where they know their farmer, they know where their food is coming from, and they trust their food,‘ explains Tobias Peggs, Square Roots co-founder. He, along with his co-founder Kimbal Musk, the younger brother of Tesla‘s Elon Musk, aim to spread out to as many American cities as they possibly can in the next five to 10 years.

By 2050 there will be nine billion people on the planet and 70 percent will leave in urban areas. These people need feeding, and they will want local, real food,” he adds.
Square Roots sells food locally. It also plans to launch more urban farms, for others to operate, and will own a share in those farms’ revenues as well. Peggs says the company, by getting hyper-local, is looking to join a global food revolution. ‘America’s is the world’s great, greatest exporter. Right? We exported rock and roll, we exported Levi’s jeans. We also exported obesity. And the feeling is, if we can solve that, in America, through initiatives like Square Roots, bringing real food to everyone, getting more people on a healthy, low-cost, sustainable food system, that we’ll also be able to export that solution.’

Metal 3D Printing Withstands Extreme Pressure And Heat

3D printed metal turbine blades able to withstand extreme pressure have been successfully tested by Siemens. It opens the way to develop high pressure components for power generators and other industries, such as aeronautics. These blades can survive temperatures above 1,250 Celsius and pressures similar to the weight of a double-decker bus.

“To have this rotating part running is a breakthrough because it is submitted to these extreme loading… It rotates with 13,600 rotations-per-minute which means it is the most highly loaded component in the whole gas turbine. So this blade that weighs 180 grams will weigh 11 tonnes while rotating with this speed,” says Jenny Nilsson, Team leader for additive manufacturing at Siemens.

Last year Siemens bought British-based Material Solutions, where the metal-based printing is being perfected. A computer-aided design model is first sent to one of these machines. Precision lasers are then fired at a thin layer of metal powder.

This is the nickel superalloy powder. This metallic powder is deposited in 20 micron layer thickness and then the laser melts the part,“explains Clotilde Ravoux, system engineer at Material Solutions.

Ultra-thin layers are added one by one, building up the part. Testing is ongoing and Siemens can’t say when these blades will be commercially produced. But they say it reduces the design-to-testing time from years to months.  “When you apply casting procedures you will probably take one to one and a half years to provide you with these blades because of their long lead-time for tooling. And by applying additive manufacturing we could significantly shorten lead time by down to three months,” adds  Christoph Haberland, manufacturing engineering.

General Electric introduced its first 3D-printed aircraft engine component into service last July. While Boeing is using metal-based 3D printing to drastically cut the production costs of its 787 Dreamliner.

Powerful Anti-Aging Cream Using Nanotechnology

Wrinkle-smoothing hyaluronic acid can now be introduced into the skin without injections, thanks to an Israeli research team that spent years developing a nanotechnology for this purpose. Facial wrinkles, lines and sagging result from the body’s gradual loss of its ability to produce hyaluronic acid. In the past, treatments of hyaluronic acid couldn’t get into the skin’s deepest layers except by injection or in a powder form that must be mixed with water and therefore loses its potency.

That problem was solved by a research team headed by Prof. Rachel Lubart and Prof. Aharon Gedanken from the departments of chemistry and physics and Bar-Ilan University’s Institute for Nanotechnology and Advanced Materials (BINA). The Israeli scientists achieved this breakthrough by micronizingbreaking down its particles to the size of a micronhyaluronic acid. Based on this development, Israeli cosmetic pharmaceuticals pioneer Hava Zingboim has created Prophecy, the first-ever cream formula that allows hyaluronic acid to penetrate into the deeper skin layers.

Once they reach nano size, the hyaluronic acid molecules are transferred into the formula, which enables them to remain nano-sized throughout the process. The effect of the micronized hyaluronic acid applied to the skin is identical to the effect achieved when injecting hyaluronic acid into the skin, with the benefits of enhanced skin texture and a younger look.
According to a university statement, this is the only technology in the world capable of creating small molecules that remain small even when applied to the skin.

Startup Promises Immortality Through AI, Nanotechnology, and Cloning

One of the things humans have plotted for centuries is escaping death, with little to show for it, until now. One startup called Humai has a plan to make immortality a reality. The CEO, Josh Bocanegra says when the time comes and all the necessary advancements are in place, we’ll be able to freeze your brain, create a new, artificial body, repair any damage to your brain, and transfer it into your new body. This process could then be repeated in perpetuityHUMAI stands for: Human Resurrection through Artificial Intelligence. The technology to accomplish this isn’t here now, but on the horizon. Bocanegra says they’ll reach this Promethean feat within 30 years. 2045 is currently their target date. So how do they plan to do it?

We’re using artificial intelligence and nanotechnology to store data of conversational styles, behavioral patterns, thought processes and information about how your body functions from the inside-out. This data will be coded into multiple sensor technologies, which will be built into an artificial body with the brain of a deceased human, explains the website.

Legally Blind People Can See With A New Kind Of Glasses

A Canadian company based in Toronto has suceeded to build a kind of Google glass that is able to give back full sight to legally blind people.  The eSight is an augmented reality headset that houses a high-speed, high-definition camera that captures everything the user is looking at.

Algorithms enhance the video feed and display it on two, OLED screens in front of the user’s eyes. Full color video images are clearly seen by the eSight user with unprecedented visual clarity and virtually no lag. With eSight’s patented Bioptic Tilt capability, users can adjust the device to the precise position that, for them, presents the best view of the video while maximizing side peripheral vision. This ensures a user’s balance and prevents nausea – common problems with other immersive technologies. A blind individual can use both of their hands while they use eSight to see. It is lightweight, worn comfortably around the eyes and designed for various environments and for use throughout the day.

eSight is a comprehensive customized medical device that can replace all the many single-task assistive devices that are currently available but do not provide actual sight (e.g. white canes, magnifying devices, service animals, Braille machines, CCTV scanners, text-to-speech software). It allows a user to instantly auto-focus between short-range vision (reading a book or text on a smartphone) to mid-range vision (seeing faces or watching TV) to long-range vision (looking down a hallway or outsidea window). It is the only device for the legally blind that enables mobility without causing issues of imbalance or nausea (common with other immersive options). A legally blind individual can use eSight not just to see while sitting down but while being independently mobile (e.g. walking, exercising, commuting, travelling, etc).

According to The Wall Street Journal, the company is taking advantages of recent improvements in technology from VR headsets and smartphones that have trickled down to improve the latest version of the eSight. So far, the company has sold roughly a thousand units, but at $10,000 apiece, they’re not cheap (and most insurances apparently don’t cover the product), although eSight’s chief executive Brian Mech notes to the WSJ that getting devices to users is “a battle we are starting to wage.”

Harvest: How To Increase The Production By Up To 40%

Nanolabs, a company specialised in nanotechnology, has been able to increase the production of melons by up to 40% on a farm in Almeria (Spain), thanks to the installation of ASAR systems in the irrigation system of the farm.
In 2015, 30,000 kilos were harvested, while in the same period of 2016, this figure increased to 50,000 kilos; a 40% growth.
To achieve this, Nanolabs applies nanotechnology through its ASAR solution, which acts physically on water, emitting a quantum of energy that stimulates hydrogen bonds. As a result, these become more active, which translates into a better transport of nutrients to the crops and a significant improvement in the use of the nutrients present in the substrate. The increase in production has not been the only benefit of the project; it has also made it possible to improve the quality of the fruit and has reduced both the consumption of water for irrigation and the use of fertilisers and phytosanitary products by 20%.
For Javier Llanes, CEO of Nanolabs, “the dramatic increase in the melon production is just one example of the great benefits that nanotechnology can bring to the agricultural sector. At Nanolabs, we apply technology to promote sustainability and we work on innovative projects with impressive results in both production improvement and savings in water consumption.”

Nuclear Energy: Fusion Power A Step Closer

The UK’s newest fusion reactor, ST40, was switched on last week, and has already managed to achieve ‘first plasma‘ – successfully generating a scorching blob of electrically-charged gas (or plasma) within its core.

The aim is for the tokamak reactor to heat plasma up to 100 million degrees Celsius (180 million degrees Fahrenheit) by 2018 – seven times hotter than the centre of the Sun. That’s the ‘fusion’ threshold, at which hydrogen atoms can begin to fuse into helium, unleashing limitless, clean energy in the process.

Nuclear fusion is the process that fuels our Sun, and if we can figure out a way to achieve the same thing here on Earth, it would allow us to tap into an unlimited supply of clean energy that produces next to no carbon emissions.Unlike nuclear fission, which is achieved in today’s nuclear reactors, nuclear fusion involves fusing atoms together, not splitting them apart, and it requires little more than salt and water, and primarily produces helium as a waste product.

 

Today is an important day for fusion energy development in the UK, and the world,” said David Kingham, CEO of Tokamak Energy, the company behind ST40. “We are unveiling the first world-class controlled fusion device to have been designed, built and operated by a private venture. The ST40 is a machine that will show fusion temperatures – 100 million degrees – are possible in compact, cost-effective reactors. This will allow fusion power to be achieved in years, not decades.

The next step is for a full set of those magnetic coils to be installed and tested within ST40, and later this year, Tokamak Energy will use them to aim to generate plasma at temperatures of 15 million degrees Celsius (27 million degrees Fahrenheit).

In 2018, the team hopes to achieve the fusion threshold of 100 million degrees Celsius (180 million degrees Fahrenheit), and the ultimate goal is to provide clean fusion power to the UK grid by 2030.

Nanoparticle Shrinks Breast Tumor, Prevent Recurrence

A Mayo Clinic research team has developed a new type of cancer-fighting nanoparticle aimed at shrinking breast cancer tumors, while also preventing recurrence of the disease. A mice that received an injection with the nanoparticle showed a 70 to 80 percent reduction in tumor size. Most significantly, mice treated with these nanoparticles showed resistance to future tumor recurrence, even when exposed to cancer cells a month later.

The results show that the newly designed nanoparticle produced potent anti-tumor immune responses to HER2-positive breast cancers. Breast cancers with higher levels of HER2 protein are known to grow aggressively and spread more quickly than those without the mutation.

In this proof-of-concept study, we were astounded to find that the animals treated with these nanoparticles showed a lasting anti-cancer effect,” says Betty Y.S. Kim, M.D., Ph.D., principal investigator, and a neurosurgeon and neuroscientist who specializes in brain tumors at Mayo Clinic’s Florida campus. “Unlike existing cancer immunotherapies that target only a portion of the immune system, our custom-designed nanomaterials actively engage the entire immune system to kill cancer cells, prompting the body to create its own memory system to minimize tumor recurrence. These nanomedicines can be expanded to target different types of cancer and other human diseases, including neurovascular and neurodegenerative disorders.”

Dr. Kim’s team developed the nanoparticle, which she has named “Multivalent Bi-specific Nano-Bioconjugate Engager,” a patented technology with Mayo Clinic Ventures, a commercialization arm of Mayo Clinic.

The findings have been published in Nature Nanotechnology.
