New Micro-Ring Resonator Creates Quantum Entanglement on a Silicon Chip

Zothecula Zothecula writes  |  5 hours ago

Zothecula (1870348) writes "The quantum entanglement of particles, such as photons, is a prerequisite for the new and future technologies of quantum computing, telecommunications, and cyber security. Real-world applications that take advantage of this technology, however, will not be fully realized until devices that produce such quantum states leave the realms of the laboratory and are made both small and energy efficient enough to be embedded in electronic equipment. In this vein, European scientists have created and installed a tiny "ring-resonator" on a microchip that is claimed to produce copious numbers of entangled photons while using very little power to do so."

Lensless Space Telescope Could be 1,000 Times Stronger Than Hubble

Zothecula Zothecula writes  |  yesterday

Zothecula (1870348) writes "The Hubble space telescope has given us decades of incredible images, but it's reaching the end of its service life and the question is, what will come after? One possibility is the Aragoscope from the University of Colorado Boulder, which uses a gigantic orbital disk instead of a mirror to produce images 1,000 times sharper than the Hubble's best efforts."

NASA and Microsoft Team Up For Virtual Mars Exploration

Zothecula Zothecula writes  |  2 days ago

Zothecula (1870348) writes "Years before the first astronauts set foot on Mars, scientists will already be there – virtually. Thanks to a collaboration between NASA and Microsoft aimed at advancing human-robot interactions, the space agency's OnSight software will allow researchers to explore a virtual Martian landscape created from data sent back by the Curiosity rover."

New Nicotine Vaccine May Succeed Where Others Have Failed

Zothecula Zothecula writes  |  5 days ago

Zothecula (1870348) writes "If you're a smoker who's trying to quit, you may recall hearing about vaccines designed to cause the body's immune system to treat nicotine like a foreign invader, producing antibodies that trap and remove it before it's able to reach receptors in the brain. It's a fascinating idea, but according to scientists at California's Scripps Research Institute, a recent high-profile attempt had a major flaw. They claim to have overcome that problem, and are now developing a vaccine of their own that they believe should be more effective."

MIT's "Better Siri" Helps You Get There on Time

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "Researchers at MIT are building a sophisticated algorithm to help with time-sensitive planning, estimating your chances of success and even suggesting alternate approaches that are more likely to succeed. The software, described by its creators as "a better Siri," could help plan projects on all scales, from long drives to air travel to multi-billion dollar NASA missions."

Nanobots Deliver Medical Payload in Living Creature for the First Time

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "Researchers working at the University of California, San Diego have claimed a world first in proving that artificial, microscopic machines can travel inside a living creature and deliver their medicinal load without any detrimental effects. Using micro-motor powered nanobots propelled by gas bubbles made from a reaction with the contents of the stomach in which they were deposited, these miniature machines have been successfully deployed in the body of a live mouse."

Prototype System Paves Way For Huge, Glasses-Free 3D Displays

Zothecula Zothecula writes  |  about a week ago

Zothecula (1870348) writes "Using red/blue filters (anaglyph), polarized (passive) or LED shutter (active) glasses are relatively simple ways of creating a 3D effect. Creating 3D pictures without viewers having to don any form of eyewear is a little trickier and is made even more so if you want really big 3D effects for a sports stadium or a billboard. To help address this, Austrian scientists working at the Vienna University of Technology (TU Vienna) and the company TriLite Technologies have developed a new kind of display just for this purpose that sends beams of light directly to the viewers’ eyes via a laser and a sophisticated mirror system."

A New Type of Glass Could Double Your Smartphone's Battery Life

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "The batteries inside our smartphones and laptops are fighting a losing battle when it comes to keeping these devices juiced up, but researchers from ETH Zurich have discovered a new type of glass material that could make a major difference: vanadate-borate glass. The glass can be used as an electrode material in lithium-ion batteries to almost double the amount of time they last between charges."

Snake Monster Robot Can be Easily Reconfigured to Suit User Needs

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "Carnegie Mellon University has created a new robot that has six legs, looks creepily like a spider when it walks, and is dubbed "Snake Monster". Not exactly endearing traits, but the Snake Monster isn’t designed to win any popularity contests. It has been created as an easily reconfigurable platform using a modular system architecture that may be easily programmed to govern robots with a varied array of configurations."

NASA Drops Mini Robots Into Volcano For Science

Zothecula Zothecula writes  |  about two weeks ago

Zothecula (1870348) writes "Space may be vast, but the planets can be pretty cramped – especially when it comes to volcanoes. This is unfortunate because the difficult to navigate fissures that are a major volcanic feature contain clues as to the interior of planets and moons and the mechanisms that formed them. To help learn more, NASA is dropping miniature robots down crevices inaccessible to humans as a way of extracting information about volcanoes on and off the Earth."

New Compound Gives Hope in Fight Against Antibiotic-Resistant Bacteria

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "Over the past quarter century, many pharmaceutical companies have largely turned their backs on the quest to develop new antibiotics, blaming difficulties surrounding the clinical trials process and turning their attention to the more profitable development of so-called "lifestyle drugs." One company bucking the trend is NovoBiotic Pharmaceuticals, which has announced the discovery of a new class of antibiotic that holds promise for treating drug-resistant superbugs."

Omnidirectional Underwater Robot Inspired by the Cuttlefish

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "Cuttlefish are fascinating animals, in that they use a pair of undulating fins to move forward and backward, turn on the spot, or hover in place. If you wanted to make an underwater robot that was highly maneuverable yet quiet and immune to tangled propellers, then the cuttlefish would be a good creature to copy. Well, a group of mechanical engineering students from Switzerland's ETH Zurich have done just that – plus they gave it an extra set of fins, allowing it to also move straight up and down."

Diet Pill Tricks Body Into Burning Fat, by Making it Think You've Eaten

Zothecula Zothecula writes  |  about three weeks ago

Zothecula (1870348) writes "When we eat a meal, our body detects that we've consumed calories and responds by burning fat in order to make room for them. The catch for the weight-conscious is that if we don't burn off those newly-arrived calories, they just end up being stored as more fat. For people with metabolic disorders or other conditions, exercise just isn't enough to keep that from happening. Soon, however, a newly-developed drug could help. It triggers the body's "burning fat to make space for calories" response, even when the patient hasn't eaten anything."

Super-Sensitive Motion Sensor Could be Used to Hunt For Extraterrestrial Life

Zothecula Zothecula writes  |  about a month ago

Zothecula (1870348) writes "People often state that certain planets are too hot, cold or toxic to support life. The catch, however, is that those people are really just talking about life as we know it here on Earth. By that same token, when rovers exploring other planets seek out chemical signatures associated with life forms, they're only able to identify chemicals that we know to look for. That's why Swiss scientists from the EPFL research center have created a device that identifies microscopic life, based on nanoscale movements instead of chemistry."

Starscraper Aims at Cheaper, Gentler Suborbital Rocket

Zothecula Zothecula writes  |  about a month ago

Zothecula (1870348) writes "The International Space Station may get all the glory, but suborbital rocket flights still play a vital part in space research. The problem is that even though such flights only go to the edge of space, they are expensive, few in number, and put massive stresses on experiments. Partly funded by a Kickstarter campaign, students at Boston University are developing an inexpensive suborbital rocket for educational purposes that uses new engine designs to create a cheaper, reusable suborbital rocket that's easier on the payload."
