Department of BIology

Two Indiana University Bloomington professors have been named recipients of the prestigious John Simon Guggenheim Fellowship for 2017. Armin P. Moczek, professor in the IU Bloomington College of Arts and Sciences’ Department of Biology, and Sara E. Skrabalak, the James H. Rudy Associate Professor in the College’s Department of Chemistry, were selected on the basis […]

Thumbnail image for Powerful ‘master gene’ regulates physical sex differences

Physical differences between males and females in species are common, but there remains much to learn about the genetic mechanisms behind these differences. New research by scientists at Indiana University finds that the “master gene” that regulates these differences plays a complex role in matching the right physical trait to the right sex. The study, […]

Scientists who study a molecule known to play a role in certain types of cancers and neurodegenerative disorders have a powerful new tool to study this compound due to research conducted at Indiana University. The study, which was published in the Proceedings of the National Academy of Sciences, shows how the extreme growth experienced by […]

A stunning image of an insect’s brain and nerve cord captured by three Indiana University scientists will be on display at the National Institutes of Health early next year. Eduardo Zattara, Armin Moczek, and Jim Powers of the IU Bloomington College of Arts and Sciences’ Department of Biology are among the winners of the Federation […]

Advancing blindness research

September 28, 2016

A $1.9 million grant to Indiana University from the National Institutes of Health’s National Eye Institute will advance basic research on the eye with applications to blindness caused by genetic disorders and aging. The five-year award to Andrew Zelhof will investigate the effect of both congenital birth defects and age on the eye using insects […]

Thumbnail image for Cyclops eyes give insight into how new traits may evolve

Beetles with cyclops eyes have given Indiana University scientists insight into how new traits may evolve through the recruitment of existing genes — even if these genes are already carrying out critical functions. The study, reported in the Proceedings of the Royal Society B, was led by Eduardo Zattara, a postdoctoral researcher in the IU […]

When Mary Ann Tellas was a freshman at Indiana University Bloomington, she had the good fortune to encounter the late Jim Holland, a professor of biology at IU Bloomington known for his tireless recruiting and mentoring of students, particularly students underrepresented on campus. “His biology course was packed with students, and I could see why. […]

Biologists at Indiana University have significantly advanced understanding of the genetic pathways that control the appearance of different physical traits in the same species depending on nutritional conditions experienced during development. In many animals, nutrition — not genetic differences — controls the appearance of certain physical traits. Ants and bees, for example, grow into workers […]

Thumbnail image for IU biologist co-leads $8.7 million grant on evolutionary development

As a recipient of an $8.7 million grant from a foundation promoting the advancement of science and philosophy, Indiana University will serve as part of the world’s largest coordinated project on the study of evolutionary biology. Armin Moczek, a professor in the IU Bloomington College of Arts and Sciences’ Department of Biology, and colleagues at […]

Thumbnail image for Gene alteration could mean new disease resistance for crops

Scientists at Indiana University have modified a plant gene that normally fights bacterial infection to confer resistance to a virus. The method, described in a paper published in the journal Science, is the first time a plant’s innate defense system has been altered to deliver resistance to a new disease. It is also the subject of […]
