CSI notwithstanding, forensics experts cannot always retrieve fingerprints from objects, but a conformal coating process developed by Penn State professors can reveal hard-to-develop fingerprints on nonporous surfaces without altering the chemistry of the print. "As prints dry or age, the common techniques used to develop latent fingerprints, such as dusting or cyanoacrylate -- SuperGlue -- fuming often fail," said Robert Shaler, professor of biochemistry and molecular biology and director of Penn State's forensic sciences program.
If every on-campus student at University Park reduced his or her time in the shower by just five minutes, Penn State would save 100,000 gallons of water each school year. That is enough to fill five swimming pools and lower the University's carbon footprint by 18,980 pounds every year.
Rising costs for fuel, fertilizers and other agricultural supplies are leading farmers to rethink their energy choices. To help them assess their energy options, the Lancaster County Center of Excellence in Production Agriculture is offering Energy on the Farm, a one-day seminar for Lancaster County and Capital and Northeast Regions farmers, from 8 a.m. to 3 p.m. Monday, Dec. 8, at the Lancaster Farm and Home Center. The seminar will provide participants with basic information about alternative and renewable energy and ways to reduce costs and generate revenue.
