Bruce Lunsford Pledges $1 Million to Establish Scholarship Program

By Jenny Wells-Hosley and Lindsey Piercy

University of Kentucky alumnus and successful Kentucky businessman Bruce Lunsford has pledged $1 million to establish the W. Bruce Lunsford Scholars Program in Citizenship and Public Service at UK. The program will support dynamic learning opportunities for students that emphasize citizenship, democracy, public service and government affairs.

From Marine Pilot to Horse Industry Data Scientist, Online Degree Grad in High Demand

By  Lindsey Piercy

Life is a balancing act, and no one understands that more than Eric Rannenberg. As a man with many titles — devoted husband, dedicated father and former Marine turned working professional — time is a valuable resource.

"Time management is critical," he said.

At just 18 years old, the Bowling Green, Kentucky, native hit the ground running. He signed on the dotted line and, with great pride, enlisted in the Marine Corps Reserve after completing high school.

Abstract: Dinoflagellates are an important group of eukaryotic microorganisms found in freshwater and marine environments. Certain dinoflagellates produce potent toxins that are the causative agents of diarrheic, amnesic, paralytic, and neurotoxic shellfish poisonings, and are responsible for the formation of harmful algal blooms (red tides). Still other dinoflagellates are capable of both photosynthesis and bioluminescence, processes that are regulated by a cellular circadian rhythm (biological clock) and give rise to bioluminescent bays and the ‘phosphorescence’ of the sea. The key, light-forming enzyme of dinoflagellate bioluminescence, dinoflagellate luciferase (LCF), contains three homologous catalytic domains within a single polypeptide and is tightly regulated by pH. The production of blue-green light by LCF is coupled to the oxidation of an open-chain tetrapyrrolic substrate, dinoflagellate luciferin (LH2), which is a catabolite of the photosynthetic pigment chlorophyll. Current progress in our understanding of LH2 biosynthesis and the chemiluminescent and pH-dependent activation mechanisms of LCF will be presented.
