Researchers at the University of Warwick have been inspired by the unique movement of trembling aspen leaves, to devise an energy harvesting mechanism that could power weather sensors in hostile environments and could even be a back-up energy supply that could save and extend the life of future Mars rovers.
Using high-performance computer simulations, EPFL researchers were able to observe how surface roughness changes when two materials rub together. Their findings, which provide insight into friction and wear mechanisms, have implications for areas ranging from engineering to the study of tectonic faults.
Simple, inexpensive urban design interventions can increase well-being and social connections among city residents, finds a new case study from the Urban Realities Lab at the University of Waterloo.
The study uses data from the Transportation Research Board's second Strategic Highway Research Program's Naturalistic Driving Study. During 2006-2015, researchers collected data from more than 3,000 drivers traveling more than 50 million miles. With this information, researchers can now see a detailed firsthand account of a driver's interaction with the vehicle, roadway and surrounding environment. Of the seven current Federal Highway Administration funded projects using this data, only MU is using the data to specifically look at highway work zones.
Cities could ease congestion and improve safety during snowstorms by tweaking the timing of traffic lights to take road conditions into account.
Before civilization can move off world it must make sure its structures work on the extraterrestrial foundations upon which they will be built. University of Central Florida researchers are already laying the groundwork for the off-world jump by creating standards for extraterrestrial surfaces. Their work was detailed recently in a study published in the journal Icarus.
Researchers have developed a technique that uses bacteria to produce 'biocement' in coal ash ponds, making the coal ash easier to store and limiting the risk of coal ash spills into surface waters.
Researchers at MIT and other universities have found that spider silk produces a strong twisting motion when exposed to humidity, and may be usable for future artificial muscles or actuators.
Canadian homeowners do not have the information they need to know if they should buy flood insurance leaving them exposed to significant financial risk. A recent study from the University of Waterloo found flood mapping information in Canada was inadequate, incomplete, hard to locate and varied widely from province-to-province.
Unstable slopes on Oregon's coastline could see a 30 percent jump in landslide movements if extreme storms become frequent enough to increase seacliff erosion by 10 percent, a new study by Oregon State University shows.
