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*).
Beckman researchers have developed a technique to measure nanometer-scale behavior of semiconductor microparticles. This will give scientists new tools to better understand how devices perform and to confirm theoretical models.
Lithium-ion batteries offer the promise of more power in a lighter package, but, as seen with recent problems in Boeing’s new 787’s, they also tend to be more susceptible to fire. Scott White, Nancy Sottos and Jeffrey Moore are looking to a nano-technological cure for this problem – deploying a thin coating of nanospheres to serve as a sub-microscopic fire brigade.
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.
Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics. Led by Beckman researcher William P. King, the Bliss Professor of mechanical science and engineering, the researchers published their results in the April 16 issue of Nature Communications.
The Spring 2013 Beckman Institute Graduate Student Seminar Series continues on Wednesday, April 24. The seminar will feature three short talks from students Alexandru Iordan, Joshua Wood and Pauline Baniqued. The seminar will be held in Beckman Institute Room 1005 and a lunch will be served to those attending the talks.
Beckman researcher Kate Clancy found that more than 20 percent of female bioanthropologists who took part in a new survey are victims of “physical sexual harassment or unwanted sexual contact” in the course of their scientific research, primarily at the hand of superior professional colleagues, even their own mentors.
