Beckman faculty member Klaus Schulten and postdoctoral researcher Juan Perilla report that they have determined the precise chemical structure of the HIV capsid, a protein shell that protects the virus’s genetic material and is a key to its virulence. The capsid has become an attractive target for the development of new antiretroviral drugs.
A new tension gauge tether (TGT) laboratory method developed by Beckman affiliate Taekjip Ha and colleagues has broad applications for research into stem cells, cancer, infectious disease and immunology.
According to Daniel Simons and colleague Christopher Chabris in a New York Times Opinion piece, "Google Glass may allow users to do amazing things, but it does not abolish the limits on the human ability to pay attention."
University of Illinois at Urbana-Champaign researchers, led by Beckman affiliate Brian Cunningham, have developed a cradle and app for the iPhone that uses the phone’s built-in camera and processing power as a biosensor to detect toxins, proteins, bacteria, viruses and other molecules. This could enable researchers and physicians in the field to run on-the-spot tests for environmental toxins, medical diagnostics, food safety and more with their smartphones.
The Beckman Institute for Advanced Science and Technology is pleased to announce the 2013 selections for the Graduate Fellows program. Eight outstanding graduate students from the University of Illinois were selected and will begin their fellowships during the Fall 2013 semester.
The Nadine Barrie Smith Memorial Fund provides fellowships to female engineering graduate students who are conducting research in the general field of medical imaging (e.g., ultrasound, optical, magnetic resonance) at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign. The Fund is pleased to offer two $4,000 fellowships for Fall 2013. More information.
Researchers report that those who plan ahead and consider how to respond positively to challenging problems tend to suffer less from anxiety than those who ignore, hide, or repress their feelings. A study revealed that those who engage in an emotional regulation strategy called reappraisal tended to also have less social anxiety and less anxiety in general than those who avoid expressing their feelings. Reappraisal involves looking at a problem in a new way, said University of Illinois graduate student Nicole Llewellyn, who led the research with Beckman affiliate Florin Dolcos, professor of psychology.
As-made single-walled carbon nanotubes consist of a mixture of both metallic and semiconducting nanotubes. This is a problem for researchers trying to fabricate electronic devices because – ideally – pure samples of either semiconducting or metallic tubes are required, depending on the application. Now, a team, led by Beckman researcher John Rogers, has come up with a new way to separate out the two types of tubes using nanoscale thermocapillary physics.
Beckman researcher Nancy Sottos is a member of the team of researchers that has developed a glue that uses DNA base pair mimics that bind to each other more strongly than their natural counterparts and may lead to glues far more powerful than Super Glue.
"In our study, we used mice that were genetically engineered to develop an aggressive form of prostate cancer. Even so, half the animals that had consumed tomato and soy had no cancerous lesions in the prostate at study's end," said John Erdman, a University of Illinois professor of food science and nutrition.
While the much-loved and iconic Alma Mater statue is being refurbished, graduates at the University of Illinois will be able to have a photo taken with a photo-realistic, high-resolution digital Alma Mater thanks to a free augmented reality application for iOS devices that displays the sculpture on its pedestal, life-sized and in real time. Travis Ross, the manager of the Visualization Laboratory at Beckman, faced the challenge of taking the 2 billion points of data from the scan and creating a simplified model that could be processed by a mobile device in real time, while retaining the high-resolution detail in its appearance
The Cognitive Science/Artificial Intelligence Steering Committee will sponsor a very limited number of awards given at the end of Spring semester 2013. The intent of the awards is to support and encourage students with interdisciplinary interest in CS/AI.
Beckman faculty member Martin Gruebele, the James R. Eiszner Endowed Chair in Chemistry and a professor of physics and of biophysics and computational biology, has distinguished himself in chemical and biological physics. Using laser manipulation techniques and computational modeling, his work has increased the understanding of protein folding in the test tube and in living cells, how energy flows through molecules and how glass surfaces morph and move.
John Rogers, Beckman researcher and professor of materials science and engineering, has led a team of researchers in developing the first digital cameras with designs that mimic those of ocular systems found in dragonflies, bees, praying mantises and other insects.
Beckman researcher William King reports that his team has measured the chemical properties of polymer nanostructures as small as 15 nm, using a novel technique called atomic force microscope infrared spectroscopy (AFM-IR).
