A teaser for Minecraft: Earth showed a pig from the game.Microsoft’s YouTube ChannelMinecraft, one of the most popular games in the world, is getting the AR treatment from Microsoft and it seems to have high potential. The official trailer for Minecraft: Earth was released on May 17, which marked the 10-year anniversary of the game.Minecraft: Earth will allow players to project their creations into the world through their smartphones. Microsoft had released a teaser video on their official YouTube channel on 6 May, showing a pig from the game walking on grass. The official reveal is grander, showing the potential of the game and urging people to “Minecraft your world”.The trailer gives viewers a glimpse of the vast potential for creativity that Minecraft: Earth will bring. It shows people placing virtual treehouses in their garden, grand castles being built at a park, a giant blue octopus enveloping houses in its tentacles, a village on a table-top, and chickens.Thus, people will have the ability to create an environment on a small surface, say, the table in a restaurant, and then take their creation out in the world and showcase it on a larger scale. Players will be able to interact with virtual wildlife and the various mobs in the game. It will also give players the ability to collaborate on projects and create something together.Microsoft hasn’t revealed how the game will be monetised, but it has been reported by Windows Central that it will be a free-to-play game without any loot boxes. The report mentions that the game will have ‘Build Plates’ on which players will build their creations, and then be able to scale the build plates to size. To create, players will have to collect blocks and go for an “Adventure” for rarer materials, such as diamonds. These personal Build Plates will also ensure that a player’s creations don’t get destroyed by others.Players are being offered a free, Earth-themed skin for their avatar in Minecraft if they register now for the Minecraft: Earth. It is available for devices running iOS 10 (or greater)and Android 7 (or greater), and registrations are available through this link. Minecraft: Earth will allow players to collaborate on projects.Minecraft.netAugmented Reality (AR)The prospect of AR technology took the world by storm when Pokémon GO released back in July of 2016. An age-old franchise with a massive following had come to life on people’s phones. Fans could catch their favourite Pokémon and get rewarded just for walking. People could not stop playing the game, even on the road. It got some criticism when people met with accidents while crossing roads or driving.Minecraft: Earth will have a slightly different take on AR with its fixed anchors. This technology allows multiple people to see the same thing, say a tower at a park, at the same place. By permanently anchoring objects’ positions and logging that on the cloud, players’ creations will stay at one location until moved.Creator Markus Persson shared his story of looking for the technology at a time when none of the tech companies in Forbes 500 were working on it. “Name a Fortune 500 tech company,” he told Wired in an interview, “I probably asked them, ‘Hey, are you working on this?'” Nobody was.That was until he met the developers of HoloLens in 2017, who were working on the exact technology he had been looking for. They decided to collaborate on the project and Minecraft became a big part of HoloLens demos. Now, Microsoft wants to let players make their own world and experience it through the lens of their phone.The development of this game is certainly something to look forward to, as it will also mark a new way to play games. The beta for Minecraft: Earth will commence in Summer this year. The full release has been rumoured to be sometime before 2020.
The researchers, led by Prof. Xiang Zhang at the University of California, Berkeley, and Lawrence Berkeley National Laboratory, have published their study in a recent issue of Nano Letters.As the researchers explain, most previous invisibility cloaks have used metallic metamaterials for cloaking at microwave frequencies. But at optical frequencies, the metal absorbs too much light and leads to significant metallic loss, and Berkeley and other groups have had to design dielectric cloaks at infrared frequencies. More recently, researchers at University of Birmingham (UK) have experimented with using uniaxial crystals as the cloak material, which can enable cloaking in visible frequencies, but only for a certain polarization of light.In the current study, the researchers used a technique called quasi conformal mapping (QCM) to conceal an object with a height of 300 nm and a width of 6 µm underneath a reflective “carpet cloak.” The carpet itself has the appearance of a smooth optical mirror, so that the object and the bump that the object makes underneath the carpet are undetectable by visible light.“The carpet cloak means that you conceal the object under a layer, which we call carpet, but you see the carpet like a normal mirror, as if it is flat with no bump caused by putting the object underneath,” Zhang told PhysOrg.com. “This way, the observer won’t recognize something is concealed underneath.”In order to guide visible light around the concealed object, the researchers had to make light travel at different speeds while approaching the bump. They achieved this by designing the materials to have a variable refractive index, transforming them into metamaterials, since they don’t appear in nature. The researchers placed a silicon nitride waveguide on a transparent nanoporous silicon oxide substrate that they specially developed to have a much lower refractive index than that of the waveguide. Using nanofabrication techniques, the researchers etched tiny holes into the nitride to make a desired pattern, giving the waveguide the cloaking refractive index profile.“The concept of the carpet cloak was originally suggested so that you can design a certain pattern for a given size of the bump, and hide an object of arbitrary shape under that,” Zhang said. “If you need to make a bigger size bump to hide a bigger object, a new hole pattern will be required.”With this refractive index profile, along with the transparency of both the waveguide and the substrate, the cloak could completely conceal an object by producing a light beam profile identical to a beam reflected from a flat carpet with no object underneath.“This device is among the first cloak devices that operate at visible frequencies; the other very recent visible light cloaks operate based on a principle that relies on a certain polarization of light, whereas the quasi-conformal-based principle does not rely on the polarization,” Zhang said. “Of course, the waveguide geometry entails different operation for different polarizations, which is extrinsic to the QCM design.”In addition to cloaking, the new technique provides an important step toward implementing optical transformation structures in the visible range. Using transformation optics (TO), researchers can manipulate light for applications such as powerful microscopes and computers.“The carpet cloak is an example of a wide family of devices that can be made based on transformation optics,” Zhang said. “Besides invisibility, all kinds of optical illusion schemes can be made based on the concept, where the observer receives a different impression when looking at an object. The capability to manipulate light propagation can be used in energy devices, optical computing devices, and beyond, wherever it is desired to have full control on the light path; TO lets us redirect light and re-route it.” This document is subject to copyright.

Miniature invisibility ‘carpet cloak’ hides more than its small size implies (PhysOrg.com) — Most of the invisibility cloaks that have been demonstrated to date conceal objects at frequencies that are not detectable by the human eye. Designing invisibility cloaks that can conceal objects from visible light has been more challenging due to the strict material requirements. But in a new study, researchers have fabricated a carpet cloak that can make objects undetectable in the full visible spectrum. When an input beam (black arrow) reflects off (a) a bump without a cloak, the bump causes a perturbation. When the beam reflects off (b) a bump covered by a cloak, the cloak masks the bump, and the reflected beam is reconstructed as if the bump did not exist. (c) Light after reflection from a flat mirror, a bump without a cloak, and a cloaked bump, at three different wavelengths.

The M6 motorway has reopened in Cheshire following a five vehicle accident that left one motorist seriously injured. The southbound carriageway was shut between Junction 19 (Knutsford) and Junction 18 (Middlewich/Holmes Chapel) following the ‘serious’ collision just after 2am this morning – with the road remaining closed until around 10.30am. A diversion was in place with Highways England, police and traffic data company Inrix all reporting the road will be closed into the morning rush hour. The collision involved two HGVs, two vans and a car that overturned, according to Highways England. A Cheshire Police spokeswoman said: “At 2.07am on Friday 29 March emergency services were called to a collision involving several vehicles on the M6 Southbound. “The collision involved two vans, a car and three lorries. The driver of one of the vehicles was taken to Royal Stoke Hospital with serious injuries. “Anyone with information should contact Cheshire Police on101 quoting IML 359640.” Investigation work continued until 8.50am, with recovery and clean-up work now ongoing.
