The inventors of self-healing plastic have come up with another invention: a new way of doing chemistry.

Researchers at the University of Illinois at Urbana-Champaign have found a novel way to manipulate matter and drive chemical reactions along a desired direction. The new technique utilizes mechanical force to alter the course of chemical reactions and yield products not obtainable through conventional conditions.

Research funded by Metallica?

Gifted students who feel the pressure of their ability could be using Heavy Metal music to get rid of negative emotions.

This is the conclusion of Stuart Cadwallader and Professor Jim Campbell of The National Academy for Gifted and Talented Youth at the University of Warwick. They will discuss their findings at the British Psychological Society’s Annual Conference at the University of York on Wednesday 21 March 2007.

Current methods used to sniff out dangerous airborne pathogens may wrongly suggest that there is no threat to health when, in reality, there may be.

But researchers have found a better method for collecting and analyzing these germs that could give a more accurate assessment of their actual threat. For example, the findings may make it easier to detect airborne pathogens in low concentrations.

Scientists from NOAA’s Earth System Research Laboratory (ESRL) announced today a new tool to monitor changes in atmospheric carbon dioxide and other greenhouse gases by region and source. The tool, called CarbonTracker, will enable its users to evaluate the effectiveness of their efforts to reduce or store carbon emissions.

The online data framework distinguishes between changes in the natural carbon cycle and those occurring in human-produced fossil fuel emissions. It also provides verification for scientists using computer models to project future climate change. Potential users include corporations, cities, states and nations assessing their efforts to reduce or store fossil fuel emissions around the world.

Engineers at Purdue University have designed and tested a "structural health monitoring" system to detect flaws that could hinder the performance of new types of military missiles made of composite materials instead of metal.

Missiles are sometimes damaged when struck by rocks and debris kicked up by helicopter rotors or when mishandled during shipping or maintenance.

Unlike missiles made of metallic alloys, which often show external signs of damage such as cracks or dents, damage in the new "filament wound" composite materials may not reveal telltale signs, said Douglas Adams, an associate professor of mechanical engineering.

Women who undergo breast enlargement often see a sizable boost in self-esteem and positive feelings about their sexuality, a University of Florida nurse researcher reports.

Although plastic surgery should not be seen as a panacea for feelings of low self-worth or sexual attractiveness, it is important for health-care practitioners to understand the psychological benefits of these procedures, says Cynthia Figueroa-Haas, a clinical assistant professor at UF’s College of Nursing who conducted the study. The findings — which revealed that for many women, going bigger is better — appear in the current issue of Plastic Surgical Nursing.
