Headlights That See Through a Downpour:Researchers have figured out how to thwart the weather when you’re behind the wheel by looking straight through the rain drops or snow that create that white-out effect when headlights meet heavy precipitation at night. By detecting and tracking individual rain droplets or snow as they fall through a car’s headlight beams, they’ve created a system that can “dis-illuminate” them by adjusting the headlight beams to only shine around them rather than on…
Quantum computing, no cooling required: Room-temperature quantum bits store data for nearly two seconds
Quantum Computing, No Cooling Required: Room-Temperature Quantum Bits Store Data for Nearly 2 2 Second Quantum bits/qubits in a solid-state system at room temperature is the Holy Grail.Lukin, Kucsko, and Latta part of a group of Harvard scientists were able to create quantum bits and store information in them for nearly two seconds, an increase of nearly 6x over the life span of earlier systems. The work has potential applications, including the construction of a functional quantum computer.
Hidden Portals in Earth's Magnetic Field:they really do exist! A portal is an extraordinary opening in space or time that connects travelers to distant realms."We call them X-points or electron diffusion regions," explains plasma physicist Jack Scudder of the University of Iowa. "They're places where the magnetic field of Earth connects to the magnetic field of the Sun, creating an uninterrupted path leading from our own planet to the sun's atmosphere 93 million miles away."
Strength in numbers: Physicists identify new quantum state allowing three -- but not two -- atoms to stick together
Physicists Identify New Quantum State Allowing 3 but not 2 Atoms to Stick Together A quantum mechanics study has discovered a new bound state in atoms that may help scientists better understand matter and its composition.It applies to 3 identical atoms loosely bound together, a behavior called 3-body bound states in quantum mechanics.3 atoms can stick together in a group but not 2. Also, 3 atoms can stick together even when any 2 are trying to repel each other and break the connection.
Cloud computing: Same weakness found in seven cloud storage services
Cloud Computing: Same Weakness Found in Seven Cloud Storage Services ScienceDaily (June 29, 2012) — Cloud storage services allow registration using false e-mail addresses and Fraunhofer SIT sees the possibility for espionage and malware distribution.
Mind reading from brain recordings? 'Neural fingerprints' of memory associations decoded
Mind Reading from Brain Recordings? 'Neural Fingerprints' of Memory Associations Decoded:Researchers have discovered ways human brains represent thoughts via a complex interplay of electrical signals.Improvements in brain recording and statistical methods have given researchers unprecedented insight into the physical processes under-lying thoughts, using brain recordings to reconstruct aspects of an image or movie clip someone is viewing, a sound or even the text someone is reading.
Dieting? Study challenges notion that a calorie is just a calorie
Study Challenges Notion That a Calorie Is Just a Calorie A new study challenges the notion that "a calorie is a calorie." Diets that reduce the surge in blood sugar after a meal--either low-glycemic index or very-low carbohydrate-may be preferable to a low-fat diet for those trying to achieve lasting weight loss. Further,a low-glycemic index diet had similar metabolic benefits to the very low-carb diet w/out neg effects of stress and inflammation as seen in the very low-carb diet.
Rewriting quantum chips with a beam of light: Laser technique brings ultrafast computing closer to reality
Rewriting Quantum Chips With a Beam of Light: Laser Technique Brings Ultrafast Computing Closer to Reality ScienceDaily (June 26, 2012) — The promise of ultrafast quantum computing has moved a step closer to reality with a technique to create rewritable computer chips using a beam of light. Researchers from The City College of New York (CCNY) and the University of California Berkeley (UCB) used light to control the spin of an atom's nucleus in order to encode information.
New toilet turns human waste into electricity and fertilizer
New Toilet Turns Human Waste Into Electricity and Fertilizer ScienceDaily (June 26, 2012) — Scientists from Nanyang Technological University (NTU) have invented a new toilet system that will turn human waste into electricity and fertilisers and also reduce the amount of water needed for flushing by up to 90 per cent compared to current toilet systems in Singapore.
Twisting Light Signals into a Vortex, Researchers Create Fastest Wireless Connection Ever: Twisting radio waves into a threaded vortex, researchers have beamed data through the air at 2.5 terabits per second, creating what has to be the fastest wireless network ever created. The technique used to create this effect has no real theoretical ceiling. In theory an infinite number of these vortex beams could be threaded together to add infinite capacity to conventional transmission protocols.
