Existence of a new quasiparticle demonstrated
Posted by Andreas Matt in categories: computing, information science, particle physics
How do molecules rotate in a solvent? Answering this question is complicated, since molecular rotation is perturbed by a very large number of surrounding atoms. For a long time, large-scale computer simulations have been the main approach to model molecule-solvent interactions. However, they are extremely time consuming and sometimes infeasible. Now, Mikhail Lemeshko from the Institute of Science and Technology Austria (IST Austria) has proven that angulons—a certain type of quasiparticle he proposed two years ago—do, in fact, form when a molecule is immersed in superfluid helium. This offers a quick and simple description for rotation of molecules in solvents.
In physics, the concept of quasiparticles is used as a technique to simplify the description of many-particle systems. Namely, instead of modeling strong interactions between trillions of individual particles, one identifies building blocks of the system that are only weakly interacting with one another. These building blocks are called quasiparticles and might consist of groups of particles. For example, to describe air bubbles rising up in water from first principles, one would need to solve an enormous set of equations describing the position and momentum of each water molecule. On the other hand, the bubbles themselves can be treated as individual particles—or quasiparticles—which drastically simplifies the description of the system. As another example, consider a running horse engulfed in a cloud of dust. One can think of it as a quasiparticle consisting of the horse itself and the dust cloud moving along with it.

Disney Brings You the Wireless-Powered Room–Is Real-Life TRON Next?
Posted by Shane Hinshaw in category: energy
Word association time. I say “quasistatic cavity resonance”; you say…?
“Whaaaa?” or “Heh heh, cavity” are expected. But if you said “enabling purpose-built structures, such as cabinets, rooms, and warehouses, to generate quasistatic magnetic fields that safely deliver kilowatts of power to mobile receivers contained nearly anywhere within,” you win the virtual no-prize.

Super-smart robots with artificial intelligence is pretty much a foregone conclusion: technology is moving in that direction with lightning speed. But what if those robots gain consciousness? Will they deserve the same rights as humans? The ethics of this are tricky. Explore them in the video below.

Handle is a research robot that stands 6.5 ft tall, travels at 9 mph and jumps 4 feet vertically. It uses electric power to operate both electric and hydraulic actuators, with a range of about 15 miles on one battery charge. Handle uses many of the same dynamics, balance and mobile manipulation principles found in the quadruped and biped robots we build, but with only about 10 actuated joints, it is significantly less complex. Wheels are efficient on flat surfaces while legs can go almost anywhere: by combining wheels and legs Handle can have the best of both worlds.

Science can help you reach enlightenment — but will it mess with your head?
Posted by Carse Peel in categories: government, neuroscience, science
A Navy SEAL, broad-chested and strongly built, floats peacefully on the water, as his recent deployment to a war-torn country becomes a distant memory.
Sealed inside a pitch-black sensory deprivation tank in the Mind Gym at Navy SEALs headquarters in Norfolk, Va., electrodes attached to his head, he has reached an altered state of consciousness referred to as “ecstasis” or “stepping outside oneself.”
It’s a state achieved by many others throughout time. High-performance athletes are in ecstasis when they ski down huge mountains or surf giant waves. Monks attain it after years of meditation. Mystics feel it when they have visions. And the US government uses it to try to reset their most elite warriors after brutal battles abroad.
