It turns out we may all be living in an infinitely large Holo-deck. That’s basically the conclusion a group of researchers reached after analyzing what is thought to be the first-ever observed evidence that the universe could in fact be a gigantic holographic projection . Phys.org reports that a team of theoretical physicists and astrophysicists from the U.K., Canada and Italy made the discovery while researching irregularities in the “cosmic microwave background,” or the “afterglow” of the Big Bang. In the course of that research, which involved using the theory of cosmic inflation, they found substantial evidence to support a holographic explanation of the universe, which actually holds as much weight as the traditional explanations for these irregularities. As Phys.org notes, the idea of a holographic universe first emerged in the 1990s, and involves the theory in which all the information that makes up our 3D reality (including time) is contained in a two-dimensional surface, on its boundaries. Scientists from Canada’s Perimeter Institute and University of Waterloo , the U.K’s University of Southampton and Italy’s University of Salento jointly made this most-recent discovery using advanced telescopes and sensing equipment that can detect data hidden in the microwaves left over from the Big Bang. As Professor of Mathematical Sciences at the University of Southampton, Kostas Skenderis explains: “Imagine that everything you see, feel and hear in three dimensions (and your perception of time) in fact emanates from a flat two-dimensional field. The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card. However, this time, the entire universe is encoded.” It’s essentially like watching a 3D movie in a theater, when the images appear to have depth, along with width and height, but they are ultimately still coming from a two-dimensional screen. Related: “Largest-ever” new map of universe shows 1.2 million galaxies “Holography is a huge leap forward in the way we think about the structure and creation of the universe.,” adds Skenderis. “Einstein’s theory of general relativity explains almost everything large scale in the universe very well, but starts to unravel when examining its origins and mechanisms at quantum level. Scientists have been working for decades to combine Einstein’s theory of gravity and quantum theory. Some believe the concept of a holographic universe has the potential to reconcile the two. I hope our research takes us another step towards this.” Via Phys.org Images via NASA and University of Southampton

Produce your own water from thin air with SunGlacier’s solar-powered DC03

If you’re alarmed by reports of dwindling water supplies across the globe, there has never been a better time to take matters into your own hands. SunGlacier founder Ap Verheggen, who has spent the better part of the last decade designing devices that harness the sun’s potential to extract water from thin air, has made his latest design available online – for free. The solar-powered DC03 relies on a Peltier element, explained in greater detail below the jump, to produce a small amount of clean water each day without a battery, without fans or an inverter, and without any moving parts that could easily degrade. The solar-powered DC03 device generates power for an 18W Peltier element. Asked to explain that in layman’s terms, Ap Verheggen told Inhabitat: “A Peltier element is a very small and thin square piece of electronics. If you connect it to electricity, it becomes hot at one side, and cold at the other side. The cold side we use to cool a cone. As the air comes at the cool cone, moisture in the air starts to condensate and produces water drops.” Water drawn from the air then drips, through gravity, into a glass (or whatever vessel each person chooses to use). Because the Peltier element has a temperature difference of 67C maximum between the upper “hot” side and the under “cool” side, according to SunGlacier, the hotter the air, the more water the device produces, bringing the group one step closer to their original ambition of improving water security for people living in desert conditions . Related: A solar-powered leaf that makes ice in the desert At the moment, the device makes about half-a-glass of water every six hours, according to SunGlacier. It is designed to operate during daylight hours only, mitigating the need for a battery. Verheggen says while the DC03 design has been thoroughly tested, it has not been optimized, which is where you come in. In the same spirit as Elon Musk’s approach to the Hyperloop , whereby he encourages anyone to improve upon the original idea, SunGlacier invites the public to take a stab at making their own solar-powered water maker using their design, which is available online . Universities and research institutes from as far afield as Iran, Romania, South-Africa and The Netherlands have already expressed an interest in getting involved, Verheggen says. This collaborative approach is expected to make SunGlacier’s groundbreaking, low-maintenance design accessible to the greatest number of people possible – and that is something we can really get behind. + SunGlacier Photos by Hessel Waalewijn

$70 DIY acoustic tractor beam moves objects with sound

Comments Off on $70 DIY acoustic tractor beam moves objects with sound

Tractor beams may soon be no longer fictional tools under the command of starship captains, as a team of researchers at the UK’s University of Bristol has managed to create a simple tractor beam out of easily obtainable parts. Check out the video above to learn how you can build your own for just over $70. https://youtu.be/6YV0lou4L4c According to the University of Bristol , the concept for this tractor beam is much simpler than a recent sonic tractor beam that uses sound waves to trap and manipulate tiny objects. According to the recent paper published in Applied Physics Letters, this tractor beam design uses just one electric signal and a passive wave modulator. As the University of Bristol notes: “The passive wave modulator is a type of acoustic lens that can alter the transmitted or reflected waves. The research team’s passive wave modulator can be made in various different ways. In one example it’s a collection of tubes with different lengths and in another it’s a carefully contoured surface. In both cases it can be 3D-printed using an off–the-shelf printer. Using a single waveform a static tractor beam can be created. If two waveforms are used then up and down manipulation of objects can be achieved.” Related: This revolutionary new paper battery is powered by bacteria According to research assistant and lead author of the paper, Asier Marzo, “The technique can generate an acoustic tractor beam using only a single electrical signal, this will reduce the cost and complexity of tractor beams making them a more affordable technology for manipulating and analyzing levitated samples. With our new research now everyone can have an acoustic tractor beam.” The device is so simple, the university has released a YouTube video showing people how they can build their own tractor beam at home for just over $70. That’s a far cry from previous tractor beam technologies, which required phased arrays of more than 50 sound channels, with each made up of a signal generator and an amplifier.

Click here to view the embedded video. The future of prosthetics is here after researchers at the Johns Hopkins Applied Physics Laboratory completed a groundbreaking experiment that gave a double amputee the ability to control his prosthetics using only his mind. Les Baugh, who lost his arms 40 years ago, became the first-ever, bilateral, shoulder-level amputee to wear two Modular Prosthetic Limbs. To control his new robotic arms, Baugh received a pair of neural implants, which give him the necessary control over his new limbs.

The amount of ice in the Arctic Ocean shrunk to an all time low in September, with the area covered now only half of what it was in the 1980s. This alarming development along with the global community’s inability to come to a consensus about cutting CO2 emissions has led Harvard professor of applied physics David Keith to look at a technological solution to reversing the warming of the Arctic. In a paper published in Nature Climate Change and an affiliated study in the Environmental Research Letters , Keith proposes a way to refreeze the Arctic through geoengineering .
