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.
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.
Layered nanocomposites containing tiny structures mixed into a polymer matrix are gaining commercial use, but their complex nature can hide defects that affect performance. Now researchers have developed a system capable of detecting such defects using a "Kelvin probe" scanning method with an atomic force microscope. The ability to look below the surface of nanocomposites represents a potential new quality-control tool for industry.
The most realistic risks about the dangers of artificial intelligence are basic mistakes, breakdowns and cyber attacks, an expert in the field says—more so than machines that become super powerful, run amok and try to destroy the human race.
Employing an ingenious microfluidic design that combines chemical and mechanical properties, a team of Harvard Univ. scientists has demonstrated a new way of detecting and extracting biomolecules from fluid mixtures. The approach requires fewer steps, uses less energy, and achieves better performance than several techniques currently in use and could lead to better technologies for medical diagnostics and chemical purification.
A Carnegie Institute-based search of nearby galaxies for their oldest stars has uncovered two stars in the Sculptor dwarf galaxy that were born shortly after the galaxy formed, approximately 13 billion years ago. The unusual chemical content of the stars may have originated in a single supernova explosion from the first generation of Sculptor stars.
