Image title	A magnetic stirrer spin a pellet in a graduated beaker filled with a liquid solution at the Gwinnett Technical College BioScience Laboratory where faculty and students from an Integrative Biology Class begin a project to study the kinetics (properties) of the enzyme tyrosinase (ty-rose’-n-ase) that they will be isolating from potatoes on Friday, March 20, 2015. Program Director Dr. Robert Powers is the instructor for this class of future clinical research professionals. Agriculture Secretary Tom Vilsack, and Labor Secretary Tom Perez, today announced the recipients of $200 million in competitive awards to fund and evaluate pilot projects in 10 states to help Supplemental Nutrition and Assistance Program (SNAP) participants enter careers and work toward self-sufficiency at Gwinnett Technical College in Atlanta, Ga, on Friday, March 20, 2015. Georgia is one of several other states that have been selected to test innovative ways to help the unemployed or underemployed transition off of government food assistance programs and compete for positions in today’s job market.
