    The total automation of exploiting living beings, what a beautiful sight. Isn't it amazing how capitalism has gone so far as to even turn animals into machines! To see all these childless mothers on that carousel is such good innovation! Then directly followed with their motherless calves drinking milk from a steel construction, what a blessing. We don't need to do this, it offers us no essential nutrients,it is destructive for the animals, the poor and the climate.

    Let us use the prospective of automation for complete human and animal liberation!

    While the automated farm doesn't look pretty, and livestock could undoubtedly be raised in less-stressful, more-natural environments if it wasn't for the overarching profit-driven economics, I think all of the machinery is actually a *good* thing, at least for the time being under capitalism.

    Perhaps think of it as the equivalent of animals not needing to go to the fridge themselves -- or needing people to 'open the fridge door for them' -- in order to get fed, and also they're obviously used to the machines and aren't freaked out or anything.

    The carousel was just for the process of automated milking, as far as I could tell, which has to be done anyway.

    More-to-the-point I'd say would be why something so essential as *food* (and good water, too, for that matter) still has to be a regular commodity when that should be the first thing taken off the market and at least distributed by the government while still under capitalism.

    Livestock shouldn't be raised it is unnecessary and harmful to the planet, humans and animals. There is no need for this whatsoever.
    Animals don't need to go to the "fridge" if we would not lock them up without a reason.
    Milking only has to be done when cows, which are mammals, are forced to be pregnant by shoving an arm in their vagina so they start lactating.
    Milk protein is a promoting factor in prostate cancer. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4166373/

    There are enough alternatives if you want to drink a milk, you don't need cow milk. https://www.ncbi.nlm.nih.gov/pubmed/20460239 You can for example use soy milk which is equal in calcium compared to milk but has way less saturated fat, and casein as shown in the first study to proliferate cancer cells.

    To you last point, im not sure what you mean? If you mean that food should be freely distributed, i totally agree, however it should not be harmful animal products.

    Undoubtedly animal liberation would accompany human liberation through socialism, and there are certainly already-available alternatives ready to go for non-monoculture farming, once society is rationally planned.

    That said, I have to put in a word for the impressive gains of the industrial revolution as applied to agriculture -- there would be no way to support the billions, albeit with billions in poverty, without machine-based production of food. And there's much left to be desired regarding the procurement of energy for the same, and other industrial methods.

    Of course we agree that industrialization of agriculture is a great development. Not for a moment should one suggest that the old ways of agriculture were somehow superior. I just think that industrialization of the animal industry is unnecessary and unwanted.

    Yes, I fucking can and do know that, as much as I do know that there is no God. Of course, there is no "evidence" - but the same goes for the possibility of Communism: This knowledge is reserved for those who are practically inclined to possess it, empirical facts will never be sufficient. Bourgeois ideologues will forever remain agnostics because true atheism necessitates faith. What you fail to understand is that we're not discussing an empirical controversy - the fascination for A.I., the pathological fear that robots will dominate humanity is an ideological perversion, and to add insult to injury, an anti-democratic, misanthropic notion. It should be obvious that it is not an accident that the pathological notion of A.I. is congruent with ecologist ideology, reducing man's social practice to animalistic traits and behaviors.

    Mayfield Robotics
    Mayfield Robotics, a Bosch start-up, is trying to make the home robot more personality-driven and lovable with the introduction of its Kuri robot today, a project that’s been in the works for nearly two years.

    We’re all likely familiar with the home robots that hit the press circuit hard, like Pepper and Jibo. But we haven’t seen any of them break into mainstream use. At this point, the Amazon Echo and Google Home are our primary home robots. They play music on command, answer our bizarre questions, and turn our smart appliances on and off. Kuri differs from these prior robots because Mayfield stressed the importance of a personality during the design process, which comes through in Kuri’s expressive eyes and demeanor.

    The voice-controlled robot is designed to do all sorts of things around the house, and unlike the Echo or Google Home, it’s on wheels. So yes, you can have a robot buddy follow you around while blasting Ludacris or whatever other music you like. At launch, however, the robot isn’t going to be natively compatible with any music streaming services, like Spotify or Apple Music, so instead, it’s going to act more like a Bluetooth speaker on wheels. Mayfield says it’s working on partnerships.


    Kuri’s equipped with a laser array to help map a user’s house and has a 1080p camera behind its eyes for remote security check-ins, the feed of which can be accessed through its companion iOS / Android app. It controls smart home devices through IFTTT and knows to automatically return to its docking station when its battery is low.

    Kuri also responds to touch if users, especially kids, don’t want or know how to use voice controls. “Hey Kuri” is its wake phrase, by the way. Like a family member, Kuri can recognize people with its built-in facial recognition software. The idea, Chris Matthews, the VP of marketing, tells me, is that when kids get home from school, Kuri will automatically send a text to their parents letting them know.

    GRID VIEW

    Mayfield Robotics
    But Kuri’s most interesting feature is what the robot lacks: a screen.

    “No screen is quite intentional,” Matthews says. If eyes ever stop being eyes and instead default back to a control page, that breaks character, he says. So to “maintain the suspension of disbelief,” Matthews and the rest of the 40-person team focused on personality that comes through without a screen.

    “A home robot should feel like closer to a pet or companion than an iPad ever could,” he says.

    I demoed Kuri yesterday and found that indeed, it’s irresistibly cute. It responded to its wake phrase and looked up at me when I brushed over its head. I drove Kuri around using manual app controls and played music over Bluetooth. It remembered where the kitchen was in our suite and navigated there while avoiding obstacles. I watched from its point-of-view through its app.

    Although this is impressive for a robot, especially the navigational features, I left disappointed. The features that make Kuri special didn’t work. Mayfield sold me on its robot’s personality and the chance to interact with an electronic family member, but I couldn’t even issue voice commands and Kuri couldn’t respond with cute light-up reactions. Mayfield says everything will be functioning when it ships. I hope that ends up being the case.

    Kuri could be a promising first release from Mayfield. Approaching robotics from a personality perspective is a novel idea, and possibly one that could make Kuri a tempting purchase. I’d be interested to see more from Mayfield when it’s further along on its Kuri release timeline. Preorders start in the US today with a $100 deposit; the bot will ultimately cost $699 when it ships toward the end of this year.

    Breakthrough paves the way for a reliable Internet service provided by balloons.

    Google parent company Alphabet's ambitious Project Loon idea is one step closer to achieving its goal of delivering Internet to underserved areas via balloons.

    In a Thursday blog post, Astro Teller, head of Alphabet's X team in charge of the company's moonshot projects, said the folks working on Project Loon recently had a "magical, serendipitous" discovery that pushed the initiative forward in a big way.

    "They've now exceeded even their own expectations for how well their smart software algorithms can help their balloons navigate the globe, and in the process they've leapt much closer to a day when balloon-powered Internet could become a reality for people in rural and remote regions of the globe," he wrote.

    The machine-learning-powered algorithms can now "send small teams of balloons to form a cluster over a specific region where people need Internet access." That's a departure from the team's original plan to create "rings of balloons" around the globe that would drift with the wind. The original idea was that as one balloon drifted out of range of a specific region, another would float along to take its place.

    Now, the balloons can "dance on the winds in small loops to remain where needed," Teller explained.

    There's several benefits to this approach.

    "We'll be able to put together a Loon network over a particular region in weeks not months, and it would be a lot less work to launch and manage," Teller wrote. "We'll reduce the number of balloons we need and get greater value out of each one. All of this helps reduce the costs of operating a Loon-powered network."

    But he cautioned: while this is a positive sign, there's still a lot of work to be done. The navigation algorithms still need improvement, and the Loon team needs to test them more extensively.

    Scientists unleash graphene’s innate superconductivity

    Colin Jeffrey Colin Jeffrey January 21, 2017


    Scientists have discovered a way to trigger the superconducting properties of graphene without actually altering its chemical structure (Credit: Colin Jeffrey/New Atlas)

    Already renowned for its potential to revolutionize everything from light bulbs and dental fillings through to semiconductors and motorcycle helmets, graphene can now add innate superconductivity to its repertoire. Scientists at the University of Cambridge claim to have discovered a method to trigger the superconducting properties of graphene without actually altering its chemical structure.

    Light, flexible, and super-strong, the single layer of carbon atoms that makes up graphene has only been rendered superconductive previously by doping it with impurities, or by affixing it to other superconducting materials, both of which may undermine some of its other unique properties.

    However, in the the latest research conducted at the University of Cambridge, scientists claim to have found a way to activate superconduction in graphene by coupling it with a material known as praseodymium cerium copper oxide (Pr2−xCexCuO4) or PCCO. PCCO is from a wider class of superconducting materials known as cuprates (derived from the Latin word for copper), known for their use in high-temperature superconductivity.

    "It has long been postulated that, under the right conditions, graphene should undergo a superconducting transition, but can't," said Dr Jason Robinson, one of the leaders of the study from the University of Cambridge. "The idea of this experiment was, if we couple graphene to a superconductor, can we switch that intrinsic superconductivity on? The question then becomes how do you know that the superconductivity you are seeing is coming from within the graphene itself, and not the underlying superconductor?"

    Using PCCO, however, which has properties well known in its long-term use in superconduction research, and by using both scanning and tunnelling microscopes to observe the effects, the scientists were able to differentiate the superconductivity generated in the PCCO from the superconductivity seen in the graphene sample.

    Superconductivity generates superconductor electrons that form into pairs, and the spin alignment of the electron pairs is dependent upon the type of superconductivity (and therefore the material) involved. PCCO has pairs of electrons with a spin state that is antiparallel – known as a "d-wave state."

    The superconductivity measured in the graphene, however, was different to the d-state wave and so must have been a different type, thereby showing that the graphene was generating its own superconductivity.

    "What we saw in the graphene was, in other words, a very different type of superconductivity than in PCCO," said Robinson. "This was a really important step because it meant that we knew the superconductivity was not coming from outside it and that the PCCO was therefore only required to unleash the intrinsic superconductivity of graphene."

    Even more tantalizing than the fact that the researchers had managed to initiate the innate superconductivity of graphene, however, was the type of wave generated using this new method. What they seemed to have produced may be the elusive "p-wave" – where electrons exhibit a spin-triplet pairing excited to a higher energy state by the absorption of radiation. This is something that physicists have been trying to prove exists for more than 20 years.

    At the moment, however, it is unclear exactly what type of superconductivity occured in the graphene, but it is certain that it did generate its own form of the phenomenon. Whether it was the elusive p-wave form remains to be verified by further experimentation.

    "If p-wave superconductivity is indeed being created in graphene, graphene could be used as a scaffold for the creation and exploration of a whole new spectrum of superconducting devices for fundamental and applied research areas," said Robinson. "Such experiments would necessarily lead to new science through a better understanding of p-wave superconductivity, and how it behaves in different devices and settings."

    By being able to consistently trigger the innate superconducting properties of graphene at will, the researchers believe that it may be possible to produce transistor-like devices in superconducting circuits, molecular electronics, and possibly new types of superconducting components for high-speed quantum computing.

    The results of this research were recently published in the journal Nature Communications.

    Default This new solar-powered device can pull water straight from the desert air

    Crystalline materials similar to these can now harvest water vapor from the air.

    This new solar-powered device can pull water straight from the desert air

    By Robert ServiceApr. 13, 2017 , 2:00 PM

    You can’t squeeze blood from a stone, but wringing water from the desert sky is now possible, thanks to a new spongelike device that uses sunlight to suck water vapor from air, even in low humidity. The device can produce nearly 3 liters of water per day for every kilogram of spongelike absorber it contains, and researchers say future versions will be even better. That means homes in the driest parts of the world could soon have a solar-powered appliance capable of delivering all the water they need, offering relief to billions of people.



    The new water harvester is made of metal organic framework crystals pressed into a thin sheet of copper metal and placed between a solar absorber (above) and a condenser plate (below).

    Wang Laboratory at MIT

    There are an estimated 13 trillion liters of water floating in the atmosphere at any one time, equivalent to 10% of all of the freshwater in our planet’s lakes and rivers. Over the years, researchers have developed ways to grab a few trickles, such as using fine nets to wick water from fog banks, or power-hungry dehumidifiers to condense it out of the air. But both approaches require either very humid air or far too much electricity to be broadly useful.

    To find an all-purpose solution, researchers led by Omar Yaghi, a chemist at the University of California, Berkeley, turned to a family of crystalline powders called metal organic frameworks, or MOFs. Yaghi developed the first MOFs—porous crystals that form continuous 3D networks—more than 20 years ago. The networks assemble in a Tinkertoy-like fashion from metal atoms that act as the hubs and sticklike organic compounds that link the hubs together. By choosing different metals and organics, chemists can dial in the properties of each MOF, controlling what gases bind to them, and how strongly they hold on.

    Over the past 2 decades chemists have synthesized more than 20,000 MOFs, each with unique molecule-grabbing properties. For example, Yaghi and others recently designed MOFs that absorb—and later release—methane, making them a type of high-capacity gas tank for natural gas–powered vehicles.

    In 2014, Yaghi and his colleagues synthesized a MOF that excelled at absorbing water, even under low-humidity conditions. That led him to reach out to Evelyn Wang, a mechanical engineer at the Massachusetts Institute of Technology (MIT) in Cambridge, with whom he had previously worked on a project to use MOFs in automobile air conditioning. After synthesizing the new zirconium-based MOF, dubbed MOF-801, Yaghi met Wang at MIT and said, “Evelyn we have to come up with a water-harvesting device.” She agreed to give it a shot.

    Device pulls water from the air
    At night setup soaks up water vapor from air, and uses heat from the sun to release it as liquid water during the day.


    V. Altounian/Science

    The system Wang and her students designed consists of a kilogram of dust-sized MOF crystals pressed into a thin sheet of porous copper metal. That sheet is placed between a solar absorber and a condenser plate and positioned inside a chamber. At night the chamber is opened, allowing ambient air to diffuse through the porous MOF and water molecules to stick to its interior surfaces, gathering in groups of eight to form tiny cubic droplets. In the morning, the chamber is closed, and sunlight entering through a window on top of the device then heats up the MOF, which liberates the water droplets and drives them—as vapor—toward the cooler condenser. The temperature difference, as well as the high humidity inside the chamber, causes the vapor to condense as liquid water, which drips into a collector. The setup works so well that it pulls 2.8 liters of water out of the air per day for every kilogram of MOF it contained, the Berkeley and MIT team reports today in Science.

    “It has been a longstanding dream” to harvest water from desert air, says Mercouri Kanatzidis, a chemist at Northwestern University in Evanston, Illinois, who wasn’t involved with the work. “This demonstration … is a significant proof of concept.” It’s also one that Yaghi says has plenty of room for improvement. For starters, zirconium costs $150 a kilogram, making water-harvesting devices too expensive to be broadly useful. However, Yaghi says his group has already had early success in designing water-grabbing MOFs that replace zirconium with aluminum, a metal that is 100 times cheaper. That could make future water harvesters cheap enough not only to slake the thirst of people in arid regions, but perhaps even supply water to farmers in the desert.

    *Update, 14 March, 12:28 p.m.: This item has been updated to reflect the fact that the device pulls nearly 3 liters of water out of the air for every kilogram of the water-absorbing material that is used.

    Discovering the world's strongest material 02:25

    (CNN)Researchers in the United Kingdom have developed a graphene-based sieve that can filter salt out of seawater, a development that could provide drinking water to millions of people around the globe.

    The applications could be a game-changer in countries where access to safe, clean, drinkable water is severely limited.

    Graphene -- an ultra-thin sheet of carbon atoms organized in a hexagonal lattice -- was first identified at the University of Manchester in 2002 and has since been hailed as a "wonder material," with scientists racing to develop inexpensive graphene-based barriers for desalination on an industrial scale.

    Now, the team at Manchester has used a compound of graphene, known as graphene oxide, to create a rigid sieve that could filter out salt using less energy.

    Overcoming hurdles

    In recent years, there had been some success in water filtration using graphene oxide to sift out other smaller nanoparticles and organic molecules.

    But researchers had struggled to move forward after finding that the membrane's pores would swell up when immersed in water, allowing particles to continue to pass through.

    Rahul Nair's team at Manchester now claims it has discovered how to control of the expansion and size of the pores.

    Writing Monday in the Nature Nanotechnology journal, the team revealed it was able to restrict pore-swelling by coating the material with epoxy resin composite that prevented the sieve from expanding. This means common salt crystals could continue to be filtered out, while leaving behind uncontaminated, clean, drinking water.

    The discovery is "a significant step forward and will open new possibilities for improving the efficiency of desalination technology," Nair said in a statement from the university.

    "This is the first clear-cut experiment in this regime. We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sieve sizes," he added.

    Global implications

    Boosting global access to water is critical. By 2025, 14% of the global population will suffer from water scarcity, the United Nations predicts. In addition, climate change is expected to wreak havoc on urban water supplies, with decreased rainfall and rising temperatures expected to fuel demand.

    Cities have been investing heavily in diversifying their water supplies, including developing new desalination technologies to make seawater potable. But existing, industrial-scale desalination plants can be costly and normally involve one of two methods: distillation through thermal energy, or filtration of salt from water using polymer-based membranes.

    These techniques have drawn criticism from environmentalists, who argue they involve large amounts of energy, produce greenhouse gases and can be harm marine organisms.

    What's next?

    The graphene-oxide breakthrough has been welcomed by scientists in the field as a promising development, but some are cautious of the next steps.

    "The selective separation of water molecules from ions by physical restriction of interlayer spacing opens the door to the synthesis of inexpensive membranes for desalination," wrote Ram Devanathan of the Pacific Northwest National Laboratory, in an accompanying news-and-views article in the journal.

    More work still needs to be done to test the durability of the barriers and to confirm the membrane is resistant to "fouling by organics, salt and biological material," he said.

    Water treatment with membranes that separate water molecules from ions, pathogens and pollutants has been proposed as an energy-efficient solution to the freshwater crisis, Devanathan added.

    "The ultimate goal is to create a filtration device that will produce potable water from seawater or waste water with minimal energy input."

    Default IBM Watson offers tech support that never sleeps

    IBM Watson offers tech support that never sleeps
    The concierge-like service can solve your issues on the spot.

    If your company uses IBM's helpdesk services, don't be surprised if you find yourself talking to Watson next time you contact the IT department. IBM has added a Watson-powered concierge-like service to its helpdesk, and it can quickly solve your IT issues around the clock, wherever you are in the world and whatever device you're using. Unlike automated bots, you can talk to Watson about your issues like you're talking to another person. It can then customize its responses -- for instance, it can use layman's terms if you're not that tech-savvy or use jargons if you are.

    It'll solve your problem on the spot if it's something simple like adding storage to an email account, resetting a password or ordering a new company phone or computer. If it's not trained to handle your problem, it'll hand you over to a human IT personnel. However, Watson learns with every interaction and with every feedback it receives and doesn't receive. (It notices if you've chosen not to answer the survey after each chat.) It draws from everything it learns, so after some time, transferring you to its human co-workers might become less and less frequent.

    Richard Esposito, IBM's general manager for GTS Mobility Services says:

    "Today, governments and enterprises need to provide an effective set of capabilities to their workforce, so that their employees can deliver a superior interaction and experience for their citizens and consumers. We need a system that can understand and communicate in a natural language conversation, one that solves problems and continues to learn while engaging with employees. Our Workplace Support Services with Watson delivers this value."
