The story headline and summary talks about "2 dimensional material", not "2 degrees of freedom for electrons to move". And the material is not quite "2 dimensional", if it was, we could stack an infinite amount of it into a box.
Also, talking about an electron having only 2 or 1 degrees of freedom for movement is per se a little weird, as electrons have been shown the ability to tunnel through barriers definitely thicker than one layer of atoms. So if electrons were actually confined to a two-dimensional space, that would at least be a property of not only one layer of atoms, but a 3-dimensional structure of considerable size.
Magnetic monopoles have been discovered as much as invisble humans have been discovered: They exist in fiction, in theories, and as clever just-sort-of-invisible surrogates in illusionist shows. In reality, though: No.
There obviously are no "2-dimensional materials", just thin, 3-dimensional layers of material that may have interesting properties. Also, I don't believe for a second that "electrons break apart" in this "mystical" matter - this will most likely turn out to be just about some fancy maths, using fractional charges to describe a model of the "interesting properties". I stopped reading when the article started fantasizing about the use in quantum computers. That's the point where you know they just want to ride some hype in lieu of some substantial results they could present. Sorry for being so pessimistic - I'm a physicist, too.
It is about a high-end taste/smell/quality food product. Germany is not a third-world country full of starving poor people. Actually, the whole EU has opted to not maximize efficiency when growing food, but mandates some efficiency-lowering rules (like on the population density of animal farms or limits on HFCS production) that favor moderation of health risks or promote quality.
I know it's a concept hard to comprehend for many who've been raised in an extremely capitalist environment, but a significant part of EU citizens actually strive for goals in their lifes other than passing away with a maximum amount of money in their bank account... so efficiency is not everything.
Just use the official press release from METRO, which was published already in February. (Yes, that's corporate propaganda, but at least their agenda to make profits is obvious, and they don't send armed people "on holiday" to fight in the Ukraine.)
Your question is leaping two steps ahead, you should ask "Have you ever eaten a carrot?", then "Have you ever eaten an unprocessed carrot?". Neither can be taken for granted anymore. Many of the younger generation have never witnessed the process called "cooking" which was so common amongst our ancestors, but were raised on food coming from factories. And even amongst those who personally witnessed the preparation of a meal one time or the other, many will only have seen a very last step of mixing/heating pre-processed ingredients, which didn't reveal much about where/how they grow.
Having seen food grow from its very beginning and then preparing a meal from has already become a rare hobby of a very few, and along with that, the ability to differentiate ingredients and their quality from taste/smell is now a rare art.
But why does the./ article amongst all possible sources reference a Russion government financed propaganda channel on this? That's like referencing the US-propaganda channel "RIAS Berlin" when talking about supermarkets in Moscow...
VR roller-coasters have been in operation at least since September 2015, see e.g. this advertisement from Europapark in Germany.
The linked article doesn't reveal anything new about such rides, the surprisingly low motion-sickness effect of such VR rides was also described 6 months ago.
Excuse me, but even after reading the linked article it eludes me how this is an advancement over existing technology like 100GBase-ZR EtherNet lines (operating at ~ 120 Gbaud per fiber)?
I once was a participant in such a "retreat". And believe me, even if you are a senior manager, you've got no way of telling your CEO that all this talk about "values" and "statements" is utter bullshit unless you actually start changing how you act, not just how you talk. But changing how you act might involve doing things with no immediate ROI seen by the C-level guys, so it does not happen. This "management retreat" stuff is just a complete waste of time.
Theoretically, if you were willing to sink a very long, disposable antenna cable along with the drone, you could activate it by very-long-wave radio. But I doubt the durability in actual sea-water, with living creatures all around, will render the "long term sitting duck"-scenario realistic, anyway. So a "timed" or "short range via audio wave" trigger might be sufficient for realistic scenarios (like false-flag bombings of countries you just don't like).
There are no "advisors" talking to you from banks, these are sales people. Their "advise" is aimed at you buying what's most profitable for the bank. Whether those advertisements are dispensed by humans or robots does not really make any difference.
I'm too very sceptical about the power consumption of this receiver: So far, all the DAB+ radios I held in hand ate battery like crazy - about 10 times the amount of a similar FM radio. So either this LG phone has some new, exciting DAB+ chipset that is way more efficient than what we've seen so far, or it's an epic fail in terms of usability.
... for the "DSR" (Digital Sattelite Radio) service was presented by Telefunken on August 20th, 1982. The DSR service was officially launched in 1989.
And yes, DSR is among the 4+ digital radio standards that already died while FM is still thriving (DSR was shut off in 1999).
You probably never listened to real-life DAB+. The abysmal rates (32kbit/s to 64kbit/s) most stations use here (because it's just so much cheaper) sound like crap in comparison to the same stations via analog FM.
Sure, DAB+ could _theoretically_ sound much better, if they weren't cheap on bandwidth, but they are.
They haven't built a single track or vehicle yet but discuss how cool the window-displays might look. Maybe one or the other potential investor would rather like to know how they could make building Hyperloop tracks at all affordable in comparison to conventional high-speed railways, and other mundane stuff...
I am still pretty convinced that the "quantum computer"-hype is based on fundamentally flawed assumptions, and that they won't break RSA (or other practical problems) of any reasonable size, that are not also easily solved with conventional computers.
Just because a model works with probabilities of "uncertain states" does not mean reality will reveal a "solution" based on all possible combinations of such states in no time. There is no compelling evidence yet that a quantum computer will find solutions quicker than it takes the real, physical hardware of that computer to take on all relevant input state combinations.
I'm prepared to bet the safety of my encrypted data on that, and I am convinced that 40 years from now, we'll look back at the hype around quantum computers the same way we today look back on the era of analog computers in the 1960s/1970s, when it was a plausible approach to solve some (back then hard-to-compute-digitally) equations, like for numerical calculus, by building physical systems (electronic circuits) that were known to behave in a way that equations could be solved by carefully adjusting some input voltages, then measuring some output voltage. We know that the precision achievable by such analog computers is very limited, and see the same problem preventing "quantum computers" from ever providing solutions that need to process a significant amount of information.
I am pretty sure we'll see more attempts on removing also other retro viruses from living human cells, if only because techniques like CRISPR/CAS9 have recently made "live editing" of genes so much more feasible.
Along with curing hereditary diseases, this is the obvious "good use case" for editing the genome in living humans.
I'm sure elsewhere in the world, researchers are also already working on the obvious "evil use cases", like breeding gene-doped athletes, unscrupulous soldiers, will-less slaves etc..

... like this bizarre episode with Riffgat in 2013? (But even Riffgat went into actual power production later.)

First, this is kind of old news, here is an official press release from the METRO corporation from February on it.
But why does the ./ article amongst all possible sources reference a Russion government financed propaganda channel on this? That's like referencing the US-propaganda channel "RIAS Berlin" when talking about supermarkets in Moscow...
What makes you assume the technology described in the linked article is good for more than the 80+ kilometers that 100GBase-RZ achieves?
But still, the above linked 100GBase-ZR specs make use of only one "color" and a single fibre - for a higher data rate.
http://www.sgf.org/fileadmin/u... As so often in medicine, "evidence" is brought forward for and against anything.
