Safe Sleeping
Parents buy millions of baby monitors each year in the U.S., but most transmit only sounds or video images of the baby - both useful, but only if a parent is listening or watching. University of Florida engineering researchers have built a prototype baby monitor that focuses on a baby's breathing. If the baby's chest stops moving, the...

Computer Search Model
Researchers at the University of Portsmouth's Sports Science and Mathematics departments and the U.S. Coast Guard are developing a computer model to predict how long someone will survive when lost at sea, which will in turn determine when to stop a search-and-rescue operation. Called the Search and Rescue Survival Model, the...

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. In...

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 an...

Brain Games
A team of scientists studying the human brain at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, report that a simple decision-making task does not involve the frontal lobes, where many of the higher aspects of human cognition, including self-awareness, are thought to originate. Instead, they...

Down to the Wires
Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded. When the modules are mechanically stretched and then released, because of the...

What's the Matter?
Scientists are on the hunt for evidence of antimatter left over from the very early Universe. Unfortunately, new results using data from NASA's Chandra X-ray Observatory and Compton Gamma Ray Observatory suggest the search may have just become even more difficult. Antimatter is made up of elementary particles, each of which has...

Solar Breakthrough
An untreated silicon solar cell absorbs only 67.4 percent of sunlight shone upon it, and the remaining unharvested light is a major barrier hampering the widespread adoption of solar power. However, a silicon surface treated with a new reflective coating developed by researchers at Rensselaer absorbs 96.21 percent of sunlight....
