Butterfly ‘Blast Badge’ a Brain Buttress
A butterfly could be a lifesaver for soldiers in war, or even down the road, workers in an explosive environment.
Mimicking the reflective iridescence of a butterfly's wing, researchers developed a color-changing patch soldiers could wear on their helmets and uniforms to indicate the strength of exposure to blasts from explosives in the field, said investigators at the University of Pennsylvania School of Medicine and School of Engineering and Applied Sciences. Future studies aim to calibrate the color change to the intensity of exposure to provide an immediate read on the potential harm to the brain and the subsequent need for medical intervention.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
