Beckman Institute researcher Emad Tajkhorshid has once again used computer simulation for a scientific breakthrough - this time he has provided insight into an important cellular recycling process in the body and shown, for the first time ever, a simulation of the binding of a molecule to a protein.
"Protein drugs have huge therapeutic potential, except they have almost no lifetime under normal physiological conditions," says Jeffrey Moore, a Beckman researcher and chemist at Illinois, who was commenting on another scientist's development of backbone-enhanced proteins.
Now you see it, soon you might not, researchers at the University of Illinois say. In computer simulations, the researchers, including Beckman affiliate Harley Johnson, have demonstrated an approximate cloaking effect created by concentric rings of silicon photonic crystals. The mathematical proof brings scientists a step closer to a practical solution for optical cloaking.
An award-winning television ad for Transport for London called "Awareness Test," about cycle safety and featuring a moon-walking bear, has come in for criticism in some quarters for its remarkable similarity to a video created in 1999 by Beckman researcher and U. of I. psychology professor Daniel Simons for the Visual Cognition Laboratory at Illinois.
"As dire as the growing problems are with a lack of enough clean water in the world, I have a great deal of hope that many of these problems can be solved by increasing research into the science and technology of water purification," said Mark Shannon, a Beckman researcher and professor of mechanical science and engineering at Illinois.
Carbon nanotubes are great one-dimensional conductors – electrically 100-fold better than copper and thermally comparable to diamond. However, they inhabit a three-dimensional world, and such small molecular conductors must find ways to properly and efficiently connect to their environment.
A paper by Justin Rhodes and collaborators for the journal Physiology and Behavior reported results that could have implications for developing pharmaceuticals that specifically target cravings for addictive drugs while leaving the desire for food intact.
The University of Illinois Urbana Champaign has developed a novel testing device for understanding the tensile properties of single nanofibers. In addition to the ability to test single nanofibers, the technology allows for testing in virtually any loading range and temperature.
Alejandro Lleras is a young Beckman Institute researcher who found his calling in the study of cognitive psychology.
Harley Johnson has joined the Beckman Institute as a member of the Computational Multiscale Nanosystems group. Johnson is a faculty member in the Illinois Department of Mechanical Science and Engineering.
The student team from the University of Illinois at Urbana-Champaign, under the leadership of Professor Ioannis Chasiotis, won in the "Characterization, Reliability, and Nanoscale Phenomenom" category by creating a design for the first MEMS platform able to perform creep and stress relaxation tests on polymeric, metallic, and biological nanofibers.
