Ridge Associated Universities, a leading national science and
technology consortium comprised of more than 100 institutions, has
awarded a University of Arkansas biologist a $5,000 seed grant to study
Jeffrey A. Lewis, an assistant
professor in the Department of Biological Sciences, was one of 35
faculty members in the nation to win the competitive award. He will use
his Ralph E. Powe Junior Faculty Enhancement Award to gain a better understanding of acetylation, a type of modification within cells that may help cells adapt to stress.
in stress defense can damage cells and have been linked to human
disorders ranging from cancer to neurodegenerative disease. Better
understanding of the process and triggers of acetylation will help
researchers better understand cell resiliency.
cells rely on a delicate balance of many different and interconnected
cellular processes,” Lewis said. “Disruption of any of these processes
can lead to catastrophic effects on cellular physiology. Cells must be
able to sense and respond to stressful situations that threaten this

Peter Ungar, Distinguished Professor and chair of the Department of Anthropology, and Luke Delezene, assistant professor of anthropology, are part of an international team working to identify fossils from Kanapoi, Kenya, with Mike Plavcan, professor of anthropology and co-director of excavations at the site.
Plavcan, co-director of
the West Turkana Paleo Project, is the primary investigator on the
National Science Foundation grant funding the research at Kanapoi with
Fredrick Kyalo Manthi of the Kenya National Museums.
Kanapoi is a 4-million-year-old fossil site on the western shore of Lake Turkana, in the north of Kenya. Plavcan and his team have been excavating there for years, and have found numerous early hominins of the species Australopithecus anamensis (a human ancestor or near cousin).
Vice Provost for Research and Economic Development
The Office of Vice Provost for Research and Economic Development has added several electronic distribution lists relating to subjects of interest to the University of Arkansas research community. More information about the types of lists and registering for them can be found here.
