(Phys.org)—In a new study, physicists at Penn State University have for the first time proposed a way to test a little-understood form of quantum mechanics called nonassociative quantum mechanics. So far, all other tests of quantum mechanics have dealt with the associative form, so the new test provides a way to explore this relatively obscure part of the theory.

“Nonassociative quantum mechanics has been of mathematical interest for some time (and has recently shown up in certain models of String Theory), but it has been impossible to obtain a physical understanding,” coauthor Martin Bojowald at Penn State told Phys.org. “We have developed methods which allow us to do just that, and found a first application with a characteristic and instructive result. One of the features that makes this setting interesting is that much of the usual mathematical toolkit of quantum mechanics is inapplicable.”

Standard quantum mechanics is considered associative because mathematically it obeys the associative property. One of the fundamental concepts of standard quantum mechanics is the wave function, which gives the probability of finding a quantum system in a particular state. (The wave function is what determines the likelihood of Schrödinger’s cat being dead or alive, before the box is opened.) Mathematically, wave functions are vectors, and the mathematical operations involving vectors and the operators that act on them always obey the associative property (AB)C=A(BC), where the way that the parentheses are set doesn’t matter.

At MIT, researchers have developed a stretchable bandage-like device capable of sensing skin temperature, delivering drugs transdermally, and containing electronics that include LED lights for displaying information. The various components of the system are designed to work together, for example the drug dispenser activating only when skin temperature is within a certain range and the LEDs lighting up when the drug reservoirs are running low. While this is only a prototype device, it certainly points toward future flexible devices that stay attached to a person’s skin, or even internally, for extended periods of time while providing health data and taking therapeutic actions in an intelligent way.

The device is based on a stretchable hydrogel matrix that reliably holds onto embedded metallic components linked by pliable wires. The hydrogel was made to have a stiffness similar to human soft tissues so that it blends well with the body when attached to it. When wires, drug reservoirs, delivery channels, and electronic components were built-in, the team tested the stretchiness of the final result showing that it maintains functionality even after repeated stress.

MOUNTAIN VIEW, Calif. — Google Life Sciences, the Silicon Valley giant’s new foray into health and medicine, announced a new name Monday that slips easily off the tongue but might sound antiquated to a high-tech, life-sciences ear: Verily.

“Verily, I swear,” as Shakespeare wrote in Henry VIII.

The word means “truly” or “certainly.” It dates back to 13th century Middle English and fell out of common use … well, a while ago. It often pops up, however, in the still very popular King James Bible.

Exciting news as another group proposes to explore telomerase therapy for the Cardio Vascular system. This no doubt follows on from DePhino et al work on the P53-telomerase-PCG-1 aging axis work which showed the effects of short telomeres on vascular aging (and other organs) and its direct link to Mitochondrial function and Stem cell Decline via the P53-telomerase-PCG-1 aging axis.

How can a person see around a blind corner? One answer is to develop X-ray vision. A more mundane approach is to use a mirror. But if neither are an option, a group of scientists led by Genevieve Gariepy have developed a state-of-the-art detector which, with some clever data processing techniques, can turn walls and floors into a “virtual mirror”, giving the power to locate and track moving objects out of direct line of sight.

The shiny surface of a mirror works by reflecting scattered light from an object at a well-defined angle towards your eye. Because light scattered from different points on the object is reflected at the same angle, your eye sees a clear image of the object. In contrast, a non-reflective surface scatters light randomly in all directions, and creates no clear image.

Flashing some interplanetary gold bling and sipping “space water” might sound far-fetched, but both could soon be reality, thanks to a new US law that legalizes cosmic mining.

In a first, President Barack Obama signed legislation at the end of November that allows commercial extraction of minerals and other materials, including water, from asteroids and the moon.

That could kick off an extraterrestrial gold rush, backed by a private aeronautics industry that is growing quickly and cutting the price of commercial space flight.
