Attention Iron Man fans. Powered suits of armor like the one designed by fictional industrialist/engineer Tony Stark may soon save or improve the lives of real people. In 2011, a motorized exoskeleton created by engineering students at the University of California, Berkeley allowed classmate Austin Whitney to walk across the stage to receive his diploma. Now, English athlete Claire Lomas is making medical history as the first paraplegic to use an exoskeleton to get around home and town.

What do Jack-O-Lanterns have to do with engineering? Plenty, if you're among the scores who participate in the pumpkin drops and launch contests that many engineering schools host around Halloween! There's even an annual World Championship Punkin Chunkin' contest in Delaware that attracts kids and adults alike.
