Researchers have discovered that protein folding is much more than just a perfunctory, fleeting performance before the real biology begins. Protein folding is a constantly ongoing, complicated biological opera itself, with a huge cast of performers, an intricate plot, and dramatic denouements when things go awry. Martin Gruebele, a professor of chemistry and member of the Nanoelectronics and Nanomaterials Group, discusses protein-folding chaperones.
Liz Stine-Morrow, professor of educational psychology and leader of the Cognition, Lifespan Engagement, Aging, and Resilience Group discusses the promise and perils of cognitive training in dementia for late-life cognitive health at the Alzheimer’s Association International Conference (AAIC) 2017, London, UK.

It took two years on a supercomputer to simulate 1.2 microseconds in the life of the HIV capsid, a protein cage that shuttles the HIV virus to the nucleus of a human cell. The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle. "We are learning the details of the HIV capsid system, not just the structure but also how it changes its environment and responds to its environment," said U of I research scientist Juan R. Perilla, who led the study with physics professor Klaus Schulten. Both were members of Beckman's Theoretical and Computational Biophysics Group. Schulten, who died in October 2016, pioneered the application of molecular dynamics simulations to study large biological systems. He called the method "computational microscopy."
Zyvex Labs, a Texas-based company that designs and constructs atomically precise manufacturing technology in order to build products with microscopic accuracy, has donated a 20-bit ZyVector scanning tunneling microscope (STM) control system to the lab of Joseph Lyding at the Beckman Institute for Advanced Science and Technology.
Gene Robinson, a professor of entomology and of neuroscience, the director of the Carl R. Woese Institute for Genomic Biology, and member of Beckman’s Intelligence, Learning, and Plasticity Group, was cited in an article about the decline of honeybee populations. “Populations have declined over the past 10 years by about 30 percent annually throughout the U.S.,” Robinson said. The article discusses how the ag industry, Illinois beekeepers, and communities across the state have come up with solutions to help honeybee populations rebound.
Paul Kenis, a professor of chemical and biomolecular engineering and a member of Beckman’s 3D Micro- and Nanosystems Group, was cited in an article in Chemistry World. Scientists at Paris Diderot University, France, and the National University of Cordoba, Argentina, have developed an inexpensive catalytic system that reduces carbon dioxide to methane at ambient pressure and temperature. “The authors describe an interesting approach, first converting carbon dioxide to carbon monoxide and then converting the carbon monoxide to methane with high selectivity,” Kenis said.
Aditi Das, an assistant professor of comparative biosciences and a member of Beckman’s 3D Micro- and Nanosystems Group, and colleagues discovered an enzymatic pathway that converts omega-3-derived endocannabinoids into more potent anti-inflammatory molecules. Chemical compounds called cannabinoids are found in marijuana and also are produced naturally in the body from omega-3 fatty acids. A well-known cannabinoid in marijuana, THC, is responsible for some of its euphoric effects, but it also has anti-inflammatory benefits. The new study in animal tissue reveals the cascade of chemical reactions that convert omega-3 fatty acids into cannabinoids that have anti-inflammatory benefits—but without the psychotropic high.
News-Gazette staff writer Paul Wood talks with Paris Smaragdis, an associate professor of computer science and of electrical and computer engineering, and a member of Beckman’s Illinois Language and Literacy Initiative. Smaragdis’ primary research interests revolve around making machines that can listen.

The center will bring together more than 90 faculty members from across campus, and numerous graduate students and postdoctoral researchers, to pursue cancer-related research.
Westerners view handshaking more positively than do East Asians, researchers report in a new study. Western men also rate handshakes initiated by men and women differently, the study found. “We know from previous studies that handshaking positively affects people’s first impressions and evaluations of others,” said U. of I. graduate student Yuta Katsumi, who led the research with U. of I. psychology professors Sanda Dolcos and Florin Dolcos. Katsumi and Florin Dolcos are members of Beckman’s Social and Emotional Dimensions of Well-Being Group.
Virtual reality (VR) and augmented reality (AR) developers promise that the technology is only limited by imagination, but wearing VR goggles for even a short period of time can cause eye strain, motion sickness, fatigue, and other physical complaints. However, a new breakthrough at the iOptics Lab (Intelligent Optics Lab) at Illinois is poised to change that. Assistant Professor Liang Gao and graduate student Wei Cui, both from the Department of Electrical and Computer Engineering and affiliated with the Beckman’s Bioimaging Science and Technology Group, have created a new optical mapping 3D display that makes VR viewing more comfortable.
A new portable device can quickly find markers of deadly, unpredictable sepsis infection from a single drop of blood. A team of researchers from the U of I—including Rashid Bashir, a member of Beckman’s 3D Micro- and Nanosystems Group—and Carle Foundation Hospital completed a clinical study of the device, which is the first to provide rapid, point-of-care measurement of the immune system’s response, without any need to process the blood.
