Anthocyanins are a class of pigments that often appear red or purple, and help give autumn leaves their distinctive colors. Anthocyanins make flowers and fruits more attractive to visually attuned pollinators and seed dispersers. Many botanists believe they also act as antioxidants, protecting less stable molecules inside cells from the occasional destructive element.

The Legacy of Frankenstein: Regenerative Biology and Medicine
Oct. 29, 2009
7:30 - 9:00 p.m.
Swain Hall West 119, IU Bloomington
In his lecture, IU Center for Regenerative Biology and Medicine Director David Stocum says he will trace the science fiction elements of Mary Shelley's Frankenstein through the technology of organ and cell transplants, the quest for the universal cell donor through embryological resurrection, and finally to the vision of chemical induction of regeneration directly at the site -- of injury -- the "holy grail" of regenerative biology and medicine. Free. For more information, please contact Benjamin Zaitlen at bzaitlen@indiana.edu.

Scientist at Work: Richard Wilk
Currently the key witness in a high profile land rights case before the Belizean Supreme Court, director of Indiana University Department of Anthropology's new booming Food Studies Program, and knee-deep in a collaborative grant designed to permanently imprint the role of sustainability on teaching at the Bloomington campus, you could say Richard Wilk's plate is full.

An Indiana University School of Optometry researcher and the IU spinout company she formed to develop a new diagnostic camera have both received grants from federal agencies to advance work toward preventing vision loss in diabetes patients. Ann Elsner, director of IU's Borish Center for Ophthalmic Research, has been awarded $379,548 from the National Institute of Biomedical Imaging and Bioengineering (NIBIB), while Elsner's IU spinout company, Aeon Imaging, has received another $247,389 from the Small Business Innovation Research program of the National Eye Institute (NEI). Both the NIBIB and the NEI are agencies within the National Institutes of Health.

Indiana University Bloomington will join seven partners in Britain and the Netherlands to investigate early human settlements in Europe. The $1.81 million (1.1 million pound) Leverhulme Trust grant, spearheaded by the Natural History Museum in London, will be distributed to collaborators over four years. Paleontologist David Polly oversees IU Bloomington's participation in the Ancient Human Occupation of Britain (AHOB) project. Among his several contributions, Polly will use diverse information to map Europe ecologically -- so he and his colleagues can get a better of idea of what human populations in different parts of Europe might have experienced.

Will neglecting to brush your teeth damage more than just your smile? Can failing to attack dental plaque increase your risk of heart damage? The answer to both questions may be "yes" if you are male and black, an Indiana University School of Dentistry study published in the current issue of the Journal of Dental Research reports.

Which comes first, depression or inflammation? To help solve this long standing chicken and egg conundrum, researchers led by Jesse Stewart, assistant professor of psychology at Indiana University-Purdue University Indianapolis asked two critical questions. Does depression lead to elevated inflammatory proteins in the human body? Or does an increase in these proteins lead to depression? They found that the answer to the first question appears to be "yes," and the answer to the second question may be "no" among healthy adults.

A group of information technology researchers at Indiana University has been chosen by the National Science Foundation to lead a four-year, $15-million project to develop new software to link together the supercomputers of tomorrow and enable new approaches to scientific research for problems of massive scale. $10.1 million will come from the NSF, with project partners providing the balance. The grant will enable construction of an experimental supercomputing network to be called FutureGrid, which will be made of almost 1,400 advanced computer processing units at Bloomington and five other locations in the United States.
