“HTC is developing a virtual reality game for its Vive headset called Front Defense, and the company plans on demoing it at the Computex conference in Taipei, Taiwan next week.”
The light field from a microcavity can be used to measure the displacement of a thin bar with an uncertainty that is close to the Heisenberg limit.
Tracking the exact location of an object is important in gravitational-wave detectors and optical cooling techniques. However, quantum physics imposes certain limits on the measurement precision. Tobias Kippenberg and his colleagues at the Swiss Federal Institute of Technology in Lausanne have devised an optomechanical device that measures the displacement of a tiny vibrating bar at room temperature with an uncertainty near the so-called Heisenberg limit. The precision of the sensor is nearly 10,000 times smaller than the zero-temperature fluctuations (zero-point motion) of the bar.
The Heisenberg uncertainty principle says—in practical terms—that any measurement of an object’s position will unavoidably give it a push that disturbs its momentum. To minimize this backaction, researchers have developed systems that couple the position of an object with the light field from an optical cavity.
Physics can be pretty intense at times, but one of the most straightforward aspects is that everything in the Universe is controlled by just four fundamental forces: gravity, electromagnetic, and strong and weak nuclear forces.
But now physicists in Hungary think they might have found evidence of a mysterious fifth force of nature. And, if verified, it would mean we’d need to rethink our understanding of how the Universe actually works.
Before we get into that, let’s go back to those four forces for a second, because they’re pretty important. They’re a fundamental part of the standard model of physics, which explain all the behaviour and particles we see in the Universe.
Temporary concept; however, those first alerts (aka help me; I fallen and can’t get up) already covers this plus with the direction we’re going with BMI in the next 5 years this will not be needed.
What if you could dial 911 by squeezing your smartphone in a certain pattern in your palm? A different pattern might turn the music on or flip a page on the screen.
New software developed by University of Michigan engineers and inspired, in part, by a Batman movie, could give any smartphone the capacity to sense force or pressure on its screen or body. ForcePhone offers new ways for people to command their mobile devices.
The software could also enable users to push a bit harder on a screen button to unlock a menu of additional options, similar to right-clicking with a mouse. The developers envision these and many other uses for their technology, which could offer the masses a coveted feature of the latest generation of smartphones.

Capitalism, at least as we know it, will probably not survive through the next decade. UBI might delay it, but the outcome is inevitable.

It’s really just a matter of time; the working man’s deal with his overseers is half dead already. But there’s still inertia in the system, and even the losers are keeping the faith. Hope dies slowly, after all.
Nonetheless, the deal is collapsing and a new wave of robots will kill it altogether. Unless the overseers can pull back on technology – very fast and very hard – the deal that held through all our lifetimes will unwind.
America’s Department of Defense (DOD) “coordinates the operational functions of the United States’ nuclear forces with a 1970s computer system that uses 8-inch floppy disks” says a report by the United States Government Accountability Office.
On January 13, US President Barack Obama, speaking at the National Cybersecurity and Communications Integration Center (NCCIC), addressed the issue of cybersecurity, one day after the official Twitter account for the US Central Command (Centcom) was hacked by supporters of the Islamic State.
Researchers recently made an important discovery in protein science that will advance our understanding of the inner workings of cells. In an article published in Scientific Reports, the team said they found a critical evolutionary link between a protein’s structure and its function.
Like tiny molecular machines, proteins handle a variety of functions from transporting chemicals to breaking food down into nutrients. The vast range of protein function is possible because of their unique gene-encoded sequence of amino acids, which affects the three-dimensional shape that folded protein chains adopt.
To better understand them, researchers have sequenced and resolved a huge number of protein structures. Currently, the Protein Data Bank includes 110,000+ structures—far more than the number with known functions. Powerful bioinformatics tools assist in making correlations between the shape and purpose of a protein, but what’s been missing is a direct structure-function link, tantamount to a Rosetta stone-like key.
