For the 2.2 million Americans battling glaucoma, the main course of action for staving off blindness involves weekly visits to eye specialists who monitor increasing pressure within the eye. Now researchers have developed an eye implant that could help stave off blindness caused by glaucoma. The tiny eye implant developed at Stanford Univ. could enable patients to take more frequent readings from the comfort of home.
Using a calculation originally proposed seven years ago to be performed on a petaflop computer, Lawrence Livermore National Laboratory researchers computed conditions that simulate the birth of the universe. When the universe was less than one microsecond old and more than one trillion degrees, it transformed from a plasma of quarks and gluons into bound states of quarks.
Univ. of Illinois engineers are bringing a touch of color to glucose monitoring. The researchers developed a new continuous glucose monitoring material that changes color as glucose levels fluctuate, and the wavelength shift is so precise that doctors and patients may be able to use it for automatic insulin dosing—something now possible using current point measurements like test strips.
There’s an old saying in the biofuels industry: “You can make anything from lignin except money.” But now, a new study may pave the way to challenging that adage. The study from the National Renewable Energy Laboratory demonstrates a concept that provides opportunities for the successful conversion of lignin into a variety of renewable fuels, chemicals, and materials for a sustainable energy economy.
Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Their device, about the size of a dime, could be used to detect the extremely rare tumor cells that circulate in cancer patients’ blood, helping doctors predict whether a tumor is going to spread.
Sandia National Laboratories’ Goma 6.0 is software for numerical simulation of multiphysics continuum processes, including moving geometry, phase-change, fluid-structural interactions, complex rheology and chemical reactions. It solves the fundamental equations of mass, momentum, energy and chemical species transport using the finite element method (FEM), which can be described by partial differential equations.
Modeling and simulation is standard practice in nearly every scientific field. Idaho National Laboratory’s Multiphysics Object Oriented Simulation Environment (MOOSE) has transformed approaches to predictive simulation, making it quick, adaptable and more accessible. MOOSE is a computer software that can be loaded onto most UNIX-compliant operating systems including, but not limited to, Mac OS X, Ubuntu, OpenSuSE, Fedora, CentOS and Redhat.
Oak Ridge National Laboratory has developed iSPM: Intelligent Software Suite for Personalized Modeling of Expert Opinions, Decisions and Errors in Visual Examination Tasks, a novel technology utilizing eye-tracking hardware, an intelligent GUI engine and advanced analytics to predict an individual’s perceptual behavior, cognitive response and risk of error for complex decision tasks such as cancer diagnosis from medical images.
Mapping of the human genome has advanced our understanding of life, health and potential cures for diseases. Many technologies could benefit from genome-level investigations. Now, a disruptive virtual scientific simulation tool that delivers a genome-level investigation for electrolytes is available. Idaho National Laboratory’s Kevin Gering has developed the Advanced Electrolyte Model (AEM), a molecular-based, scientifically proven simulation tool.
MIT Lincoln Laboratory’s Airborne Sense and Avoid (ABSAA) Radar Panel is a stepped-notch antenna array that marks a substantial advance in the fabrication of wide-bandwidth radar systems for use aboard unmanned aerial systems (UAS). The panel provides high performance by incorporating multifunction radio-frequency integrated circuits using a commercially available, high-volume silicon germanium (SiGe) 0.13-μm foundry process.
Chemochromic pigments can be very robust hydrogen leak indicators due to their highly visible, long-term stability and reliable chemical reactions between the pigments and hydrogen. However, their implementation is often difficult because of environmental interference and gas permeability of the host materials. Patented research from the Univ. of Central Florida and HySense Technology LLC solves the known issues by combining a palladium-oxide chemochromic pigment in a novel silicon matrix that is environmentally resistant while being hydrogen permeable.
Lawrence Livermore National Laboratory scientists have developed a new polishing system capable of finishing flat and spherical glass optics in a single iteration, regardless of the workpieces’ initial shape. Convergent Polishing: Rapid, Simple, Low Cost Finishing of High Quality Glass Optics is able to “converge” several steps because factors contributing to non-uniform spatial material removal on the workpiece have been eliminated and the creation of rogue particles within the polisher system have been removed.
Laboratory-grown replacement organs have moved a step closer with the completion of a new study. Scientists have grown a fully functional organ from transplanted laboratory-created cells in a living animal for the first time. They have created a thymus, an organ next to the heart that produces immune cells known as T cells that are vital for guarding against disease.
Efforts to reduce carbon dioxide emissions will factor heavily into engine development by OEMs, and this will be accomplished in large part from the reduction of internal friction. Daimler AG has made a significant advance in this area with the introduction of NANOSLIDE, an innovative coating for cylinder running surfaces of combustion engines to reduce CO2 emissions, which allows for the use of lighter crankshafts and reduces friction losses in the piston assembly.
GP:50 Corp. has announced the introduction of its Model 216/316 Series, a family of compact, long range, high line differential pressure transducers. The GP:50 Model 216/316 Series is available in pressure ranges from 2.5” wcd thru 200 psid (14 bar), with line pressure options up to 5000 psi (345 bar).
