George Francis has been a pioneer in using technology to explore the connections between art and mathematics.
Beckman Institute researcher Jeffrey Moore, graduate student Mary Caruso, and their collaborators are reporting on a new approach to creating self-healing materials that is much less expensive and much more practical than the original system developed by Moore and Beckman colleagues Nancy Sottos and Scott White.
The next Beckman Institute Graduate Student seminar will be held on Wednesday, December 5 at Noon in Room 1005 at the Beckman Institute. This is the final seminar of the Fall series and it will feature the following presentations: "4-Dimensional Intuition: Can We See In 4D?" by Mike Ambinder; "Limits on Learning Language Constraints from Speech Production Experience" by Jill Warker; and "Designing Nano Aggregate Probes for Surface Enhanced Vibrational Spectroscopy" by Anil Kodali. The hour-long seminar is open to the public and a pizza lunch will be served.
At this month's giant Society for Neuroscience conference in San Diego, one challenge to the neurogenesis theory came from Shawn Kohler, a graduate student at the Beckman Institute. William Greenough, a Beckman faculty member, is beginning to be able to label neurons in animals by when the cells were born and follow them through time.
John Stone, a senior research programmer at the U. of I.'s Beckman Institute, comments on the efficiency of turning graphics processing units into supercomputers.
Using an extremely sensitive measurement technique, researchers including Beckman faculty member Yi Lu have found clear evidence that a lead-specific DNAzyme uses the "lock and key" reaction mechanism. In the presence of zinc or magnesium, however, the same DNAzyme uses the "induced fit" reaction mechanism, similar to that used by ribozymes.
Frequent physical exercise on activity wheels, which are a rat's equivalent of a treadmill, was found to stimulate the birth of new brain cells in young laboratory rats with brain damage resembling the prenatal effects of binge drinking by pregnant human females. U. of I. neuroscientist William Greenough reports that new brain cells, including neurons as well as supportive glial cells, were generated at much higher rates in the physically active rats than in the rodents whose cages were not connected with activity wheels. "These findings in animals are expected to lead to treatments for humans with brain damage caused by their mother's alcohol consumption," Greenough says.
The next Beckman Institute Graduate Student seminar will be held on Wednesday, November 14 at Noon in Room 1005 at the Beckman Institute. The following presentations will be featured: "DNA Ligation for Permanent Colloidal Assembly" by Margaret Shyr; "Functional connectivity in the aging brain" by Michelle Webb Voss; and "Carbon Nanotube for High-Performance Flexible Electronics" by Qing Cao. The hour-long seminar is open to the public and a pizza lunch will be served.
Mark Nelson's laboratory at the Beckman Institute is one of the premier facilities in the country for studying weakly electric fish and their unique sensory abilities, but his research career didn't start with biology or neuroscience. Nelson is a physicist.
According to Alejandro Lleras, a psychology professor at the U. of I.'s Beckman Institute, learning to detect cell phone rings and vibrations is part of a perceptual learning process. "When we learn to respond to a cell phone, we're setting perceptual filters so that we can pick out that (ring or vibration), even under noisy conditions," Lleras said
Beckman's Integrated Systems Laboratory and psychology researchers have combined to create a novel experiment for studying pedestrian distraction during traffic situations. WCIA reporter Sara Jindra interviewed Beckman's Hank Kaczmarski and Jim Crowell to discuss how the CUBE is making this research possible.
