The best at switching back and forth between tasks seem to be 20-somethings, based on research at Illinois. People ages 7 to 82 were asked to switch between two memory tasks in some simple numeric experiments. Both ends of the age spectrum did poorly, with young kids faring worst, says Art Kramer, Beckman researcher and U. of I. professor of psychology.
The Beckman Institute Graduate Student Seminar Series presents the work of outstanding graduate students working in Beckman research groups. The seminars are open to the UIUC campus. The November 8 seminar begins at noon in Room 1005 of the Beckman Institute.
The advancements wrought by the unremittent scaling down of transistors are obvious to anyone who uses a cell phone, portable music player, or laptop - and that includes most Americans these days. Beckman Institute researcher Paul Kenis believes the miniaturization of chemical processes could change the way some of those electronic devices are powered.
U. of I. researchers not only have discovered an unusual phenomenon in which ultra-narrow wires show enhanced superconductivity when exposed to strong magnetic fields, they also have developed a theory to explain it. As reported in the Sept. 29 issue of Physical Review Letters, U. of I. physics professor and Beckman affiliate Alexey Bezryadin and his research group have studied the effect of applying a magnetic field to ultra-narrow superconducting wires only a few hundred atoms across, and have used a microscopic theory proposed by physics professor Paul Goldbart and his team to explain the results.
On Wednesday Oct. 25 the Beckman Institute will be playing host to a show that features stories and pictures of the weird and wacky, a professor who had one of his students dress up in a gorilla suit, and opera singers belting out tunes about inertia.
U. of I. scientists have created polarized, spherical particles that self-assemble into clusters with specific shapes and distributions of electric charge. The researchers say the polarized particles can be used in the directional self-assembly of intricate shapes and unique structures. "The world abounds with particles that have traditionally been treated as geometrically symmetric, chemically isotropic and electrically uniform," says Steve Granick, a Beckman affiliate and U. of I. professor of materials science and engineering, chemistry and physics. "We have muddied the waters a bit by asking: 'What happens when we build clusters from particles that have an uneven distribution of electric charge?' "
Beckman Institute faculty member William O'Brien has been a pioneer in developing ultrasound imaging techniques for use in clinical applications. Recently, through a collaboration with University of Illinois at Chicago nursing professor Barbara McFarlin, and with UIUC professors Michael Oelze and James Zachary, O'Brien has applied his quantitative ultrasound imaging methods toward development of a new tool for the prevention of miscarriages.
Fourth grade students at Derby Academy in Hingham, Mass., are using Bugscope, a computer software created by Illinois's Beckman Institute that allows participants to communicate with an environmental scanning electron microscope by means of a remote computer.
Harry Shum, Managing Director of Microsoft Research Asia, will present "Prior, Context and Interactive Computer Vision" at the Beckman Institute on Friday, October 6 at Noon in Room 1005.
The Beckman Institute Graduate Student Seminar Series presents the work of outstanding graduate students working in Beckman research groups. The seminars are open to the UIUC campus. The next seminar takes place on Wednesday, October 11 at noon in Room 1005 of the Beckman Institute.
A paper in the August issue of Psychology Press by several Beckman faculty members takes issue with the notion of memory free searches for items or locations within a display that have already been inspected.
If you simply rely on the superficial in evaluating writer Richard Powers, you might be baffled by what appear to be contradictions. Powers, a Beckman affiliate and the author of eight critically acclaimed novels that often examine how we respond to the soul-numbing technological changes that surround us, rides a bicycle to his campus office.
