MRI Can Replace CT Scans, Reducing Cancer Risks
New studies by radiologists have shown that MRI can be just as accurate as CT scans at helping radiologists diagnose pathologies such as cancer, cysts and kidney stones -- while carrying less risk, ... > more -
Computer Scientists Develop Portable Evidence-Gathering Tool
Investigators on a crime scene can now use a new tool for collecting chemical or biological samples. The sampler gun collects samples on a cotton pad -- eliminating direct contact with anything ... > more -
New Software Helps Track the Path of Toxic Spills
Ecological engineers have developed software that can model the path of a toxic spill in waterways anywhere in the United States. The system can predict if and when a contaminant will reach a ... > more -

Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
Engineers Devise Implantable Dosimeter to Track Success of Radiation Therapy
Radiologists could soon measure the amount of radiation exposure experienced by different tissues using an implantable capsule. The device contains a small dosimeter and sends radiation exposure data ... > more -
Human-Factors Engineers Focus on User-Friendliness
Human-factors engineers -- whose training includes psychology -- specialize in testing products for usability, for example checking whether a copying machine's legs get in the way, or measuring how ... > more -
Engineers Establish Accuracy and Usability Standards
Human-factors engineers, along with the National Institute of Standards and Technology (NIST) have developed a rigorous, standardized test for all electronic voting machines -- whose error rate is ... > more
