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.

Stephen Hawking Warns: Only 100 Years Left For Humankind Before Extinction

It’s no secret that physicist Stephen Hawking thinks humans are running out of time on planet Earth.

In a new BBC documentary, Hawking will test his theory that humankind must colonize another planet or perish in the next 100 years. The documentary Stephen Hawking: Expedition New Earth, will air this summer as part of BBC’s Tomorrow’s World season and will showcase that Hawking‘s aspiration “isn’t as fantastical as it sounds,” according to BBC.

For years, Hawking has warned that humankind faces a slew of threats ranging from climate change to destruction from nuclear war and genetically engineered viruses.

While things look bleak, there is some hope, according to Hawking. Humans must set their sights on another planet or perish on Earth.

We must also continue to go into space for the future of humanity,” Hawking said during a 2016 speech at Britain’s Oxford University Union. In the past, Hawking has suggested that humankind might not survive another 1000 years without escaping beyond our fragile planet.” The BBC documentary hints at an adjusted timeframe for colonization, which many may see in their lifetime.

3D Printing Art And Design in Paris

Do you plan  to travel to Paris? In this case do not miss to visit the Centre Pompidou,  this huge museum, located in the center of Paris and dedicated to modern Art.  You can assist to  “Mutations/Créations“: a new event decidedly turned towards the future and the interaction between digital technology and creation; a territory shared by art, innovation and science.

Drawing on all the disciplines in a mix of research, art and engineering, the first edition of this annual event calls upon music, design and architecture. It consists of two exhibitions (“Imprimer le monde“ and “Ross Lovegrove“), an Art/Innovation Forum entitled “Vertigo“, and various study days and get-togethers. Each year, thematic and monographic exhibitions will be staged around meetings and workshops that turn the Centre Pompidou into an “incubator“: a place for demonstrating prototypes, carrying out artistic experiments in vivo, and talking with designers. This platform will also be a critical observatory and a tool for analysing the impact of creation on society. How have the various forms of creation begun using digital technologies to open up new industrial perspectives? How do they question the social, economic and political effects of these industrial developments, and their ethical limits? What formal transformations have come about in music, art, design and architecture with regard to technical and scientific progress?


In the same space,  you can see a  new retrospective devoted to British designer Ross Lovegrove, which shows how the artist has introduced a fresh dialogue between nature and technology, where art and science converge. He employs a “holistic“ idea of design through a visionary practice that began incorporating digital changes during the 1990s, rejecting the productivism of mass industry and replacing it with a more economical approach to materials and forms. This exhibition emphasises the role of design in the postindustrial era, now that we are seeing a significant shift from mechanics to organics: a changeover symptomatic of our times, which these “digital forms“ endeavour to highlight.

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.

Your browsing history may be up for sale soon

A US House committee is set to vote on whether to kill privacy rules that would prevent internet service providers (ISPs) from selling users’ web browsing histories and app usage histories to advertisers. Planned protections, proposed by the Federal Communications Commission (FCC) that would have forced ISPs to get people’s consent before hawking their data – are now at risk. Here’s why it matters.

Your web browsing patterns contain a treasure trove of data, including your health concerns, shopping habits and visits to porn sites. ISPs can find out where you bank, your political views and sexual orientation simply based on the websites you visit. The fact that you’re looking at a website at all can also reveal when you’re at home and when you’re not.

spy your dataIf you ask the ISPs, it’s about showing the user more relevant advertising. They argue that web browsing history and app usage should not count as “sensitiveinformation.
Not all ISPs want to abolish the privacy protections. A list of several smaller providers – including Monkeybrains.net, Cruzio Internet and Credo Mobile – have written to representatives to oppose the decision. “One of the cornerstones of our businesses is respecting the privacy of our customers,” they said.
How does this differ from the way Google and Facebook use our data?
It’s much harder to prevent ISPs from tracking your data. You can choose not to use Facebook or Google’s search engine, and there are lots of tools you can use to block their tracking on other parts of the web, for example EFF’s Privacy Badger.

Consumers are generally much more limited for choice of ISP, in some cases only having one option in a given geographical area. This means they can’t choose one of the ISPs pledging to protect user data.

Virtual Images that Blend In And Interact With The Real-World

Avegant, a Silicon Valley startup that sells a pair of headphones equipped with a VR-like portable screen, is breaking into augmented reality. The company today announced that it’s developed a new type of headset technology powered by a so-called light field display.

The research prototype, which Avegant eventually plans on turning into a consumer product, is based on the company’s previous work with its Glyph projector. That device was a visor of sorts that floats a virtual movie screen in front of your eyes, and developing it gave Avegant insight into how to build an AR headset of its own.

Like Microsoft’s HoloLens and the supposed prototype from secretive AR startup Magic Leap, Avegant’s new headset creates virtual images that blend in and interact with the real-world environment. In a demo, the company’s wired prototype proved to be superior in key ways to the developer version of the HoloLens. Avegant attributes this not to the power of its tethered PC, but to the device’s light field display — a technology Magic Leap also claims to have developed, yet has never been shown off to the public.

The demo I experienced featured a tour of a virtual Solar System, an immersion within an ocean environment, and a conversation with a virtual life-sized human being standing in the same room. To be fair, Avegant was using a tethered and bulky headset that wasn’t all that comfortable, while the HoloLens developer version is a refined wireless device. Yet with that said, Avegant’s prototype managed to expand the field of view, so you’re looking through a window more the size of a Moleskine notebook instead of a pack of playing cards. The images it produced also felt sharper, richer, and more realistic.

In the Solar System demo, I was able to observe a satellite orbiting an Earth no larger than a bocce ball and identify the Big Red Spot on Jupiter. Avegant constructed its demo to show off how these objects could exist at different focal lengths in a fixed environment — in this case a converted conference room at the company’s Belmont, California office. So I was able to stand behind the Sun and squint until the star went out of focus in one corner of my vision and a virtual Saturn and its rings became crystal clear in the distance.

SpaceX Hyperloop A Step Closer To Reality

The Hyperloop high-speed transportation system has moved a step closer to reality. Teams competed to design subscale versions of the transport pods that could one day whisk passengers between San Francisco and Los Angeles in under half an hour. The competition was hosted by SpaceX and its founder, Elon Musk. Although Musk is not directly involved in the construction of the Hyperloop, the billionaire entrepreneur originally envisioned the concept, having created an open-source plan that encouraged others to build it. The idea is that passengers would travel through low-pressure steel tubes at up to 800 mph (1,288 kph), propelled by a magnetic accelerator. The fastest pod in the competition reached 58mph (93 kph). That was designed and built by a 35-person team from the Technical University of Munich, Germany.

What made our team stand out is actually a compressor which we bought out of an old aircraft. It’s there to reduce drag and give us some additional speed.” A team from Delft University of Technology in the Netherlands achieved the highest overall score in the competition for their pod with a levitation, stabilization and braking system based on permanent magnets“, said Josef Fleischmann, member of the WARR team from Technical University of Munich.

Hyperloop, the technology is pretty much there already, we just have to implement it. One of the things this competition is for is to show the world that we can do this and convince them that we should build it somewhere and get the ball rolling,” explains Mars Geuze, technical of Delft Hyperloop.
SpaceX has said it will hold a second competition, open to both new and existing student teams, in Summer 2017, this time focused only on maximum speed.

First Driverless Electric Bus Line Opened In Paris

Shuttling their way to a greener city. Paris opening its first driverless buses to the public on Monday. Fully electric and fully autonomous, the ‘EZ 10‘ transports up to 10 passengers across the Seine between two main stations. The buses use laser sensors to analyse their surroundings on the road and for now they don’t have to share it with any other vehicles.

“Fewer people come on board, its slower, its electric, it doesn’t pollute and it can be stored away more easily but it will never replace a traditional bus“, says Jose Gomes, who has been driving buses here for 26 years. He’ll oversee the smooth operation of the autonomous bus.

The shuttles come as Paris faces high pollution levels. City mayor Anna Hidalgo wants to reduce the number of cars, while authorities crack down on traffic restrictions. It may be a short 130m stretch for the buses but for Paris, it’s a big step towards promoting cleaner transport.

£25,000 To Fabricate A New Beer According To Your DNA

Can’t quite find the perfect pint? A London brewer claims to have the answer – a beer designed around your DNA profile. The Meantime Brewing Company in Greenwich says designing a product to suit a particular person’s palate is a world first.

meantime-beerCLICK ON THE IMAGE TO ENJOY THE VIDEO

What we looked at doing was trying to create a beer where we could produce a beer specifically to that person, so looking at their DNA to understand the taste profile of the individual to then say OK, you particularly identify bitter flavours, sweet flavours what have you and then produce a beer which has that characteristic so you would ultimately like that beer and it would be a great beer to taste and it would suit your taste buds perfectly.” explains Ciaran Giblin, Brewmaster at Meantime Brewing Company.

Launching in February, Meantime Bespoke customers will have their DNA analysed They’re looking for variations in the gene that allows us to taste bitter compounds like those found in cabbage, coffee and certain dark beers. Then it’s back to the brewery and tried and tested variations of barley, hops, yeast and water.

It’s about interpreting all these different facets to bring it together to produce one beer that someone is going to like. So it’s a complex process. It’s not a simple case of just putting it all in together and off it goes. There’s lots of elements that we’ve got to draw in together to focus on in order to deliver the beer that is perfect for someone to drink,” comments Ciaran Giblin.

Customers will pay 25,000 pounds for the privilege – and for a little extra can impact the whole process of creating a new beer .

You have influence on what the label looks like, on what the taste of the beer looks like. You can even get a glass perfectly formed to your hand so you can enjoy it in the perfect way. A glass can influence the flavour of the beer as well. So it really ticks off every box that you go through and then you get to share it with friends or if you’re a business or wherever you go,” says Richard Myers, Marketing Director of the company. Customers will get 12 hectolitres of their unique brew in bottles – more than 2,000 pints It can also be delivered in kegs to your favourite pub – where you’ll have even more friends than you realised.

The Rise Of The Hydrogen Electric Car

Right now, if you want an alternative-fuel vehicle, you have to pick from offerings that either require gasoline or an electrical outlet. The gas-electric hybrid and the battery-powered car — your Toyota Priuses, Chevy Volts, and Teslas — are staples in this space. There are drawbacks for drivers of both types. You still have to buy gas for your hybrid and you have to plug in your Tesla — sometimes under less than favorable conditions — lest you be stranded someplace far away from a suitable plug. Beyond that, automakers have been out to find the next viable energy source. Plug-in vehicles are more or less proven to be the answer, but Toyota and a handful of other carmakers are investigating hydrogen.

toyota-mirai

That’s where the Toyota Mirai comes in. The Mirai‘s interior center stack has all the technology you would expect from a car that retails for $57,500, including navigation, Bluetooth, and USB connectivity. It’s all accessible by touch screens and robust digital displays.
A fill-up on hydrogen costs just about as much as regular gasoline in San Francisco. The Mirai gets an estimated 67 MPGe (67 Miles per gallon gasoline equivalent = 28,5 kilometers per liter)), according to Toyota.
It’s an ambitious project for Toyota because the fueling infrastructure for this car is minimal. There are only 33 public hydrogen-filling stations in the US, according to the US Department of Energy. Twenty-six of those stations are in California, and there’s one each in Connecticut, Massachusetts, and South Carolina.

If you include public and private hydrogen stations, then the total climbs to 58 — nationwide. Compare that to the more than 15,100 public electric-charging stations and the 168,000 retail gas stations in the US, and you can see the obvious drawback of hydrogen-powered cars. Despite this, the Mirai is an interesting project, and you must keep in mind that Japan at the Government level seems to bet on a massively hydrogen powered economy in the near future (fuel, heating, replacement of nuclear energy, trains, electric vehicles, etc…).

Japan Bets On Hydrogen As A Green Energy Source

Hydrogen gas is a promising alternative energy source to overcome our reliance on carbon-based fuels, and has the benefit of producing only water when it is reacted with oxygen. However, hydrogen is highly reactive and flammable, so it requires careful handling and storage. Typical hydrogen storage materials are limited by factors like water sensitivity, risk of explosion, difficulty of control of hydrogen-generation.

alstom-hydrogen-electric-train Hydrogen gas can be produced efficiently from organosilanes, some of which are suitably air-stable, non-toxic, and cheap. Catalysts that can efficiently produce hydrogen from organosilanes are therefore desired with the ultimate goal of realizing safe, inexpensive hydrogen production in high yield. Ideally, the catalyst should also operate at room temperature under aerobic conditions without the need for additional energy input. A research team led by Kiyotomi Kaneda and Takato Mitsudome at Osaka University have now developed a catalyst that realizes efficient environmentally friendly hydrogen production from organosilanes. The catalyst is composed of gold nanoparticles with a diameter of around 2 nm supported on hydroxyapatite.

The team then added the nanoparticle catalyst to solutions of different organosilanes to measure its ability to induce hydrogen production. The nanoparticle catalyst displayed the highest turnover frequency and number attained to date for hydrogen production catalysts from organosilanes. For example, the  converted 99% of dimethylphenylsilane to the corresponding silanol in just 9 min at room temperature, releasing an equimolar amount of hydrogen gas at the same time. Importantly, the catalyst was recyclable without loss of activity. On/off switching of hydrogen production was achieved using the nanoparticle catalyst because it could be easily separated from its organosilane substrate by filtration. The activity of the catalyst increased as the nanoparticle size decreased.

A prototype portable hydrogen fuel cell containing the nanoparticle catalyst and an organosilane substrate was fabricated. The fuel cell generated power in air at room temperature and could be switched on and off as desired.

Generation of hydrogen from inexpensive organosilane substrates under ambient conditions without additional energy input represents an exciting advance towards the goal of using hydrogen as a green energy source.

The Biggest Solar Plant Ever Built produces electricity at $0.10/kWh

The massive, 648-megawatt array was officially linked to the grid after being hooked up to a 400kV substation, the operator Adani Green Energy Ltd announced. The plant is spread across 2,500 acres in the town of Kamuthi in the Ramanathapuram district (India)  and will supply enough clean, green energy for 300,000 homes. The Deccan Chronicle reported that the $679 million solar park consists of 380,000 foundations, 2.5 million solar modules, 576 inverters, 154 transformers and 6,000-kilometers of cables. The plant was built with parts and machinery from around the world. Adani Group chairman Gautam Adani formally dedicated the structure to the nation.

“This is a momentous occasion for the state of Tamil Nadu as well as the entire country“, he said. “We are extremely happy to dedicate this plant to the nation; a plant of this magnitude reinstates the country’s ambitions of becoming one of the leading green energy producers in the world.”

India has an ambitious solar energy goal. In 2014, Indian Prime Minister Narendra Modi announced plans to increase solar power capacity to 100 gigawatts by 2022, five times higher than the previous target.

The plant was commissioned by Tamil Nadu chief minister J Jayalalithaa. Indian Express reported in July 2015 that the state government would buy the entire 648 megawatts produced by Adani at a fixed price of $0.10/kWh (Rs 7.01/kWh) for 25 years.
