Researchers develop low-cost stop-sign warning system
Researchers at the University of Texas at San Antonio believe they have found a low-cost solution to improving safety when driving rural roads at night. The Rural Area Vehicle Detection, as it is called, is a solar-powered warning system that alerts drivers to an upcoming stop sign, reports UTSA Today. The system’s thermal-energy technology detects […]

Scientists develop regenerating bio-concrete using solid-state fermentation
Scientists at the University of Waikato in New Zealand have developed a protocol called solid-state fermentation that uses nanobiotechnology to make a concrete that regenerates itself to repair cracks as they develop. Researchers around the world have been working on the same thing, but Waikato researchers Dr. Aydin Berenjian and PhD student Mostafa Seifan have […]

Fungus-powered, self-healing concrete could eliminate cracks in existing roads, bridges
Binghamton University researchers are working on perfecting a fungus that will heal the cracks that naturally form in concrete, pressconnects.com reports. To make the self-healing concrete, fungal spores and a nutrient-based medium would be added to the concrete during the mixing process or sprayed onto concrete structures already built. The fungus would naturally secrete minerals […]

Adding paraffin oil to concrete can create roads that de-ice themselves
Drexel University researchers have discovered that adding a little paraffin wax to a road’s concrete mix could create roads that deice themselves, EurekAlert! reports. A paper published in Cement and Concrete Composites written by researchers led by Yaghoob Farnam, an assistant professor in Drexel’s College of Engineering, explains how substances like paraffin oil — known […]

Researchers develop system to improve GPS accuracy in cities up to 90%
In the bustle of a city full of traffic, narrow streets, tall buildings, trees and other obstacle, GPS can have a hard time accurately locating a vehicle whether its your family sedan, or your dozer. In an open field, the margin of error of GPS location is 50 feet. But urban settings increase that mark […]
