Engineers have taken a leaf out of nature's book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible and lightweight robot hands for industrial applications and novel prosthetic devices.
Scientists have observed the point at which classical and quantum behavior converge. Using a fiber-based nonlinear process, the researchers were able to observe how, and under what conditions, "classical" physical behavior emerges from the quantum world.
One infrared scan can give pathologists a window into the structures and molecules inside tissues and cells, enabling fast and broad diagnostic assessments, thanks to an imaging technique developed by University of Illinois researchers and clinical partners.
Researchers have made an experimental breakthrough in explaining a rare property of an exotic magnetic material, potentially opening a path to a host of new technologies.
As nanotechnology makes possible a world of machines too tiny to see, researchers are finding ways to combine living organisms with nonliving machinery to solve a variety of problems. Like other first-generation bio-robots, the new nanobot engineered at the University of Illinois at Chicago is a far cry from Robocop. It's a robotic germ.
In a study, a team of scientists at the University of Wisconsin-Madison has developed a new, faster approach to analyze all the data that will come out of the new, super-advanced Square Kilometer Array (SKA), a radio telescope planned for Africa and Australia that will have an unprecedented ability to deliver data on the location and properties of stars, galaxies and giant clouds of hydrogen gas.
Until now, doctors have been able to measure bone loss — a process that happens slowly, over time — but haven’t had the means for gauging actual bone strength. That has changed thanks to a new handheld instrument. Called the OsteoProbe, the device uses reference point indentation (RPI) to measure mechanical properties of bone at the tissue level.
VICI Valco’s Cheminert C52 Series Injector presents an integrated motor/valve assembly designed specifically to be built into an OEM system. Using the well-proven Cheminert HPLC injector design and the 24-V motor from the company's popular microelectric actuators, the C52 needs only to be connected to the instrument’s power supply. Control is simplified to require a single contact closure; the injector’s position is determined by whether the closure is held high or low.
New research conducted at the University of Kansas Medical Center has found a correlation between milk consumption and the levels of a naturally-occurring antioxidant called glutathione in the brain in older, healthy adults.
The latest generation of halogenated coolants is a big step forward: these substances decay more quickly in the atmosphere hence their lifetimes are considerably shorter. That is why they do not add nearly as much to the greenhouse gas effect as their stable predecessors.
An experimental drug that attacks brain tumor tissue by crippling the cells' energy source called the mitochondria has passed early tests in animal models and human tissue cultures, say Houston Methodist scientists.
Physicists inspired by the radical shape of a Canberra building have created a new type of material which enables scientists to put a perfect bend in light. The creation of a so-called topological insulator could transform the telecommunications industry's drive to build an improved computer chip using light.
Scientists have coaxed stem cells to grow the first three-dimensional mini lungs. Previous research has focused on deriving lung tissue from flat cell systems or growing cells onto scaffolds made from donated organs.
An experiment devised in Griffith University's Centre for Quantum Dynamics has for the first time demonstrated Albert Einstein's original conception of "spooky action at a distance" using a single particle.
Long before Mercury, Venus, Earth and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths, planets larger than Earth but smaller than Neptune. If so, those planets are long gone, broken up and fallen into the sun billions of years ago largely due to a great inward-and-then-outward journey that Jupiter made early in the solar system's history.
