University of Illinois food scientists have developed an acoustic technique that provides for much closer inspection of food containers than is currently possible through ordinary visual inspection

Arrays Of Hundreds Of Identical Millimeter-sized Machines May Replace Conventional Mechanical Devices
Taking a leaf from microelectronics manufacturers, who have perfected methods to produce millions of transistors simultaneously, Stanford researchers are pioneering development of massively parallel mechanical systems consisting of arrays of hundreds of mechanisms ranging in size from a few hundreds to an inch to the width of a human hair.

Common Carbohydrates May Prove To Be Substitute For Dietary Fiber
It may be possible to get the disease-fighting benefits of bran -- without having to eat bowlsful of the stuff -- by switching to smaller amounts of certain fruits and vegetables, says a University of Illinois scientists

Novel Solid-State Mid-Infrared Laser Nearing Reality, Scientists Say
A novel concept for making a tunable, mid-infrared semiconductor laser has been moved a step closer to reality at the University of Illinois

Herpes-Based Gene Therapy Is Key To Promising Liver Tumor Vaccine
Physicians from the University of Rochester's Cancer Center and Memorial Sloan-Kettering Cancer Center have created a promising compound that recruits the body's immune system to target and wipe out cancer cells in the liver.

Cell-Membrane Proteins Appear To Play Key Role In Squid's Swiftness
University of Illinois and Stanford University spent time combing the California coast, and they've unlocked a possible reason for the squid's high-speed, jet-propelled swimming behavior.

Amorphous Silicon-Based Solar Cells Come Into Their Own
Three companies will mass-produce amorphous silicon-based solar cells this year, which may spell the beginning of commercially cost effective solar power, according to a Penn State researcher.

Results of NICHD Study of Early Child Care Reported at Society for Research in Child Development Meeting
New research being released this week by the National Institute of Child Health and Human Development (NICHD)indicates that the quality of child care for very young children does matter for their cognitive development and their use of language.

Value Of Space Technology Transfer Assessed By RFF
As the launch date nears for the first commercial remote sensing satellite, Resources for the Future is helping the National Aeronautics and Space Administration find a reliable way to measure the economic return from its transfer of formerly-classified space technologies to the public and private sectors.

Satellites And Sensors To Be Used For Better Control Of Crop Pests
It's only a matter of time before pest infestations can be mapped with hand-held computers linked to global positioning satellite receivers, allowing more accurate pest control, say University of Illinois researchers

Stress-Reduction Benefits Of Exercise Demonstrated In Study
New research conducted at the University of Illinois suggests that exercise is much more effective at reducing stress than is merely sitting still

Skill Key To Level Of Complexity
The number and type of mistakes made while manufacturing obsidian blades may help archaeologists to better understand the social and economic structure in ancient Mexico, according to a Penn State anthropologist.

NIAID Evaluates N-9 Film As Microbicide
A large two-year study supported by the National Institute of Allergy and Infectious Diseases showed that vaginal contraceptive film containing nonoxynol-9 had no effect on transmission of HIV/AIDS, gonorrhea or chlamydia infections when provided as part of an overall HIV/STD prevention program

Discovery Of Ancient Obsidian Quarry Helps Define Prehistoric Andean Trade Networks
The discovery of an ancient quarry high in the Peruvian Andes, where prehistoric peoples mined and knapped volcanic glass, is providing the first hard evidence that long-distance trade was taking place in the Americas as far back as 2,500 B.C

Corn Byproduct Shows Promise As Biodegradable Packaging Material
A byproduct from corn refining shows promise as a key ingredient for the manufacture of water-resistant, biodegradable, plastic-like food containers, according to food scientists at the University of Illinois

Climate Shift Would Aid Industrial Nations, Hurt Less-Developed Ones
Global climate change will help many industrialized nations and adversely affect many underdeveloped nations, according to a recent analysis of 184 countries by the University of Illinois at Urbana-Champaign.

Simple -- And Cheap -- Process Can Double Life Of Rechargeable Batteries
A simple, inexpensive process developed at the University of Illinois could double the life of rechargeable batteries

Latest Evidence of Global Warming Presented To AAG
Ohio State University researchers warn that the most compelling evidence for recent global warming may be found in the tropics and subtropics, not in the polar regions where early signs of warming are anticipated. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
