Researchers from Beth Israel Deaconess Medical Center (BIDMC) in Boston are developing an imaging system that will essentially light up and color cancerous tumors, enabling surgeons to evaluate whether they've resected an entire diseased area. The system, called fluorescence- assisted resection and exploration - or FLARE - is...

Deadly Contaminant Sensor

The blood-thinning drug heparin is highly effective when used to prevent and treat blood clots in veins, arteries, and lungs, but contaminated heparin products recently caused serious allergic reactions that led to many deaths. Now, University of Michigan researchers have demonstrated a simple, inexpensive method for...

Internet In Outer Space

Engineers from NASA's Jet Propulsion Laboratory in Pasadena, Calif., used software called Disruption-Tolerant Networking, or DTN, to transmit dozens of space images to and from a NASA science spacecraft located more than 32 million kilometers (20 million miles) from Earth. The successful experiment could pave the way for...

Examining Simulation Software Trends

Analysis and simulation software continues evolving to keep up with a changing market. Virtual prototyping is enabling designers to simulate a design on the computer instead of building a physical prototype, and examine why a product will fail or succeed when physical testing is unable to explain the results....
