Engineers Create Roll Up Conductors To Save Chip Space
2012-12-14 13:34:45

University of Illinois On the road to smaller, high-performance electronics, University of Illinois researchers have smoothed one speed bump by shrinking a key, yet notoriously large element of integrated circuits. Three-dimensional rolled-up inductors have a footprint more than 100 times smaller without sacrificing performance. The researchers published their new design paradigm in the journal Nano Letters. “It´s a new concept for old technology,” said team leader...

“Bio-bots” Making Tracks In Synthetic Biology
2012-11-15 19:37:10

University of Illinois They´re soft, biocompatible, about 7 millimeters long — and, incredibly, able to walk by themselves. Miniature “bio-bots” developed at the University of Illinois are making tracks in synthetic biology. Designing non-electronic biological machines has been a riddle that scientists at the interface of biology and engineering have struggled to solve. The walking bio-bots demonstrate the Illinois team´s ability to forward-engineer...

Stickleback's Aggressive Behavior Studied
2012-11-15 18:15:46

University of Illinois at Urbana-Champaign With a mate and a nest to protect, the male threespined stickleback is a fierce fish, chasing and biting other males until they go away. Now researchers are mapping the genetic underpinnings of the stickleback's aggressive behavior. Armed with tools that allow them to see which genes are activated or deactivated in response to social encounters, a team from the University of Illinois has identified broad patterns of gene activity that...

Nano-manufacturing Improved With Nanometer-scale Diamond Tips
2012-11-14 15:39:36

University of Illinois at Urbana-Champaign One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat.  High speed and high temperature have been known to degrade the tip“¦ until now. “Thermal processing is widely used in manufacturing,” according to William King, the College of Engineering Bliss Professor at...

Disappearing Biocompatible Electronics
2012-09-28 11:33:00

[ Watch the Video: Transient Electronic Circuit ] April Flowers for redOrbit.com - Your Universe Online A research team from Northwestern University, the University of Illinois at Urbana-Champaign and Tufts University has demonstrated "transient electronics" for the first time. Transient electronics are electronic devices that gradually disappear on a specified schedule, whether it is within a few days or six months. The applications for these kinds of electronics are innumerable,...

Low-powered Nanotweezers May Benefit Cellular-level Studies By Demonstrating New Capabilities
2012-09-17 17:08:19

Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power “optical nanotweezers” can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples. “We already know that plasmonic nanoantennas enhance local fields by up to several orders of magnitude, and thus, previously showed that we can use these structures with a regular CW laser source to make...

A study from University of Illinois economics professors demonstrates a new method to analyze the relationships among voters´ issue preferences, the candidates´ policy positions and voter behavior. Estimating the distribution of voter preferences and the extent of policy divergence between the candidates´ platforms, economics professors Stefan Krasa and Mattias Polborn are able to separate observed changes in voter behavior into those driven by voter radicalization versus...

A Look At The Early Evolution Of Sex Chromosomes
2012-08-06 18:24:30

Two new studies offer insight into sex chromosome evolution by focusing on papaya, a multimillion dollar crop plant with a sexual problem (as far as growers are concerned) and a complicated past. The findings are described in two papers in the Proceedings of the National Academy of Sciences. The research reveals that the papaya sex chromosomes have undergone dramatic changes in their short evolutionary histories (they are about 7 million years old; by comparison, human sex chromosomes...

Sand Diverted From River To Rebuild Wetlands Using Spillways
2012-07-25 08:42:43

Researchers could have a new method to rebuild wetlands of the Louisiana delta, thanks to a chance finding while monitoring severe flooding of the Mississippi River. A team of civil engineers and geologists from the University of Illinois, in collaboration with the U.S. Army Corps of Engineers, published their findings in the journal Nature Geoscience. In the spring and summer of 2011, high floodwaters on the Mississippi prompted the corps to open the Bonnet Carre spillway. The spillway...

Resolution And Durability Improved By Microscope Probe-sharpening Technique
2012-07-06 12:06:52

A simple new improvement to an essential microscope component could greatly improve imaging for researchers who study the very small, from cells to computer chips. Joseph Lyding, a professor of electrical and computer engineering at the University of Illinois, led a group that developed a new microscope probe-sharpening technique. The technique is described in research published this week in the journal Nature Communications. Scanning probe microscopes provide images of tiny structures...
