A liquid does not have to be a disordered bunch of particles. A team of researchers at Vienna University of Technology and the University of Vienna has discovered intriguing structures formed by tiny particles floating in liquids. Under mechanical strain, particle clusters in liquids can spontaneously form strings and alter the properties of the liquid.
Choline, a nutrient found in foods such as egg yolks, liver and soybeans, does not appear to be high on anyone’s list of eating priorities, say University of Alberta researchers. But it’s crucial to a number of biological functions, and the liver doesn’t naturally produce enough to deliver the full benefits.
A team of scientists at Kyoto University has reported producing viable sperm using the stem cells of mice in an experiment that researchers hope could one day lead to treating infertile men.
China Medical Technologies, Inc., a China-based advanced in-vitro diagnostic (“IVD”) company, and Leica Biosystems, a division of Leica Microsystems, recently announced that they have established a sales, research and development collaboration to co-develop and market automated FISH kits to be used on the Leica BOND system.
A team from University of Massachusetts Amherst has discovered a fundamental, previously unknown property of microbial nanowires in the bacterium Geobacter sulfurreducens that allows electron transport across long distances that could impact nanotechnology and bioelectronics.
The new TC Cloud service from Fujitsu, which will be introduced in phases beginning in the third quarter of 2011, is comprised of three services, including a platform for conducting analytical simulations, and analytical applications service, and an analytical help desk, which provides support for setting up and running analytical simulations.
More than a decade ago, the frequency comb technique that allows accurate measurement of optical frequencies was developed at the Max Planck Institute in Germany. Now, researchers there have built new a new comb tool that spans more than an octave and is precisely tunable.
As long ago as the Wright Brothers' first airplane engine, metallurgists were using nanoparticles to make strong aluminum alloys. Researchers at Lawrence Berkeley National Laboratory have now solved the mystery of one of the most promising alloys ever for strength, hardness, lightness, and resistance to corrosion and heat, one that includes core-shell nanoparticles all nearly the same size.
FEI Company has announced its Versa 3D DualBeam system, which provides high-resolution 3D imaging and analysis on a wide range of sample types. Versa 3D is available with either high vacuum-only or high and low vacuum electron imaging hardware.
Omega Engineering's OMDC-125 series is a variable speed controller for PM, shunt wound, and universal motors.
Using a newly developed type of spectroscopy, researchers in Germany have for the first time shown that electrons in a semiconductor are best described as a cloud with a size of a few nanometers. The cloud size is determined by the interaction of the electron with vibrations in the crystal lattice.
Molecules that suddenly transform into new structures when stimulated by photons or electrons play key roles in many chemical and biological processes. But their inner workings remain mysterious because the charge-transfer dynamics happen too quickly for detection by typical instruments. A new ultrafast laser spectroscopy method deeveloped at RIKEN in Japan is able to track these changes, uncovering a remarkable phenomenon.
Companies like Google and Zappos.com are famous for their "work hard, play hard" attitudes and friendly work environments, but are their employees healthier too? According to a Tel Aviv University researcher, a positive relationship with your co-workers has long-term health benefits.
University of Minnesota researchers have discovered and received a patent for a naturally occurring lantibiotic—a peptide produced by a harmless bacteria—that could be added to food to kill harmful bacteria like salmonella, E. coli and listeria.
Haydon Kerk has recent designed a new type of linear actuator to control the power to a cement mixer aboard a piece of heavy construction equipment. The actuator is completely sealed to withstand dirt, debris, heat, and moisture.
