Researchers have created a 3D image of a material referred to as "liquid smoke."

Could combustion without flames be used to build industrial gas turbines for power generation that are much more efficient than current models and produce almost no polluting emissions? Researchers in the Middle East provide a possible answer in the current issue of the Inderscience publication, International Journal of the Environment and Pollution.

National Institute of Standards and Technology (NIST) fire protection engineers turned an abandoned New York City (NYC) brick high-rise into a seven-story fire laboratory last month to better understand the fast-moving spread of wind-driven flames, smoke and toxic gases through corridors and stairways of burning buildings.

Scientists and engineers in Georgia and Pennsylvania are reporting development of a new, low-cost material for capturing carbon dioxide from the smokestacks of coal-fired electric power plants and other industrial sources before the notorious greenhouse gas enters the atmosphere.

Computer scientists from UC San Diego have developed a way to generate images like smoke-filled bars, foggy alleys and smog-choked cityscapes without the computational drag and slow speed of previous computer graphics methods.

While the government spends billions of dollars on educational and prevention programs to persuade teens not to do things like smoke, drink or do drugs, a Temple University psychologist suggests that competing systems within the brain make adolescents more susceptible to engaging in risky or dangerous behavior, and that educational interventions alone are unlikely to be effective.
