Scientist at Work: Mark Kelley

Mark Kelley Day in and day out, cancer fighter Dr. Mark Kelley is about trying to find a safe way to knock cancerous tumor cells out of action, while at the same time protecting a patient's normal cells from damage. His work at Indiana University's Melvin and Bren Simon Cancer Center -- studying the use of DNA repair genes as a therapeutic tool in different chemotherapy programs -- is highly specialized, but he also knows answers to his problems may lie within the work some other researcher is doing in another corner of the same building.  Full Story

Prehistoric pelvis offers new clues to human development

Gona pelvis

Discovery of the most intact female pelvis of Homo erectus may cause scientists to reevaluate how early humans evolved to successfully birth larger-brained babies. "This is the most complete female Homo erectus pelvis ever found from this time period," said Indiana University Bloomington paleoanthropologist Sileshi Semaw. "This discovery gives us more accurate information about the Homo erectus female pelvic inlet and therefore the size of their newborns."

"Lost" Miller-Urey experiment created more of life's building blocks

Miller-Urey original experiment

A classic experiment proving amino acids are created when inorganic molecules are exposed to electricity isn't the whole story, it turns out. The 1953 Miller-Urey Synthesis had two sibling studies, neither of which was published. Vials containing the products from those experiments were recently recovered and reanalyzed using modern technology. The results were reported in a recent issue of Science.

Indiana University's Field Lab to infuse new life into research and teaching

Field Laboratory

Indiana University scientists, students and administrators gathered recently to celebrate the construction of the 6,000-square-foot Research and Teaching Preserve Field Laboratory, the university's newest science building. When the Field Lab is completed, likely in spring 2009, university architects will ask that the Field Lab be awarded LEED certification, an acknowledgement of the structure's tiny environmental footprint.

IU and Purdue form consortium to further energy-related research

Wind Turbine

Indiana University and Purdue University have again joined forces, this time to expand research exploring crucial issues surrounding energy production, distribution and use. The two institutions have jointly created the Indiana Consortium for Research in Energy Systems and Policy to advance interdisciplinary research related to energy systems and environmental and energy policy issues. Members of the consortium include IU Bloomington, Purdue University in West Lafayette and Indiana University-Purdue University Indianapolis.

NIH to give IU $2.7 million to explain how embryos take their shape

Somite failure mechanisms

A Biocomplexity Institute team led by Indiana University Bloomington biophysicist James Glazier with collaborators András Czirók, Randy Heiland, Charles Little, Herbert Sauro and Santiago Schnell is set to receive $2.7 million from the National Institutes of Health to expand studies of early animal development, addressing age-old problems in developmental biology.

Einstein's relativity survives neutrino test

Physicists working to disprove "Lorentz invariance" -- Einstein's prediction that matter and massless particles will behave the same no matter how they're turned or how fast they go -- won't get that satisfaction from muon neutrinos, at least for the time being, says a consortium of scientists. The test of Lorentz invariance, conducted by MINOS Experiment scientists and reported in the Oct. 10 issue of Physical Review Letters, started with a stream of muon neutrinos produced at Fermilab particle accelerator, near Chicago, and ended with a neutrino detector 750 meters away and 103 meters below ground.

Geoffrey Fox

The June 17, 2008, issue of IU Discoveries featured an article on Geoffrey Fox -- an IU professor in the School of Informatics who is working to bring predictability to the natural world. This issue also included a story about the $25 million clinical research grant awarded to IU, details on the IU coal geologist who received a national honor, details on the 2008 Gill Award recipients, an in-depth look at the IU Cyclotron, and a feature on a donut made of a math maze.
