New research suggests that the relatively large crystals used to change several properties of light in lasers -- changes that are crucial for making lasers into practical tools -- might be created by stacking up far smaller, rod-shaped microcrystals that can be grown easily and cheaply.
This article describes spherical tokamak as model for limitless energy.
Chemists at the University of Texas at Arlington have published a new study that indicates that highly variable contamination events registered in and around unconventional oil and gas developments are the result of operational inefficiencies and not inherent to the extraction process itself.
Gaston is currently sitting smack in the middle of the Atlantic Ocean churning away. Currently it is not near any landmasses and is at tropical storm status having weakened slightly from hurricane force.
Each year, millions of people -- especially those 65 and older -- fall. Such falls can be serious, leading to broken bones, head injuries, hospitalizations or even death. Now, researchers from the Sinclair School of Nursing and the College of Engineering at the University of Missouri found that sensors that measure in-home gait speed and stride length can predict likely falls. This technology can assist health providers to detect changes and intervene before a fall occurs.
How genes in our DNA are expressed into traits within a cell is a complicated mystery with many players, the main suspects being chemical. However, a new study by University of Illinois researchers and collaborators in China has demonstrated that external mechanical force can directly regulate gene expression. The study also identified the pathway that conveys the force from the outside of the cell into the nucleus.
When an important bridge collapsed on Interstate 5 near Mount Vernon, Washington, in 2013, questions were raised about how such a catastrophic failure could occur. A new analysis by a team of civil engineering faculty at the University of Illinois at Urbana-Champaign outlines the many factors that led to the collapse, as well as steps that transportation departments can take to prevent such accidents on other bridges of similar design.
Depending on the intensity track of Typhoon Lionrock, it could pass over Japan with the strength of a lion or or the weakness of a lamb. The intensity track is not clear as yet and some forecasters have it remaining a stronger storm while others have it downgrading significantly in intensity.
Chemists at the University of Waterloo have developed a long-lasting zinc-ion battery that costs half the price of current lithium-ion batteries and could help enable communities to shift away from traditional power plants and into renewable solar and wind energy production.
Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that 'remember' their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures -- from small coils and multimaterial flowers, to an inch-tall replica of the Eiffel tower -- sprang back to their original forms within seconds of being heated to a certain temperature 'sweet spot.'
