Everyone knows that exposure to pollution during rush hour traffic can be hazardous to your health, but it's even worse than previously thought. In-car measurements of pollutants that cause oxidative stress found exposure levels for drivers to be twice as high as previously believed.
Robotics researchers have found a way for autonomous underwater vehicles to navigate strong currents with greater energy efficiency, which means the AUVs can gather data longer and better.
A ground-breaking new study challenges the assumption that moral decisions are strongly context dependent and cannot be modeled or described algorithmically, finding that human behavior in dilemma situations can be modeled by a simple value-of-life-based model. The research suggests that human moral behavior can be well-described by algorithms and used by machines to manage moral dilemmas on the road.
Ribbon halfbeak are a species of fish with the ability to fly above the sea surface -- but unlike true 'flying fish', they lack the necessary hind wing fins. So how do they fly? Dr. Yoshinobu Inada from Tokai University, Japan says, 'Investigating the design of ribbon halfbeak could provide useful information for the optimal design of tandem wing airplanes.'
The hype around hydrogen fuel cells has died down, but scientists have continued to pursue new technologies that could enable such devices to gain a firmer foothold. Now one team has developed an electrocatalyst to replace the currently dominant, but expensive, one of choice -- platinum -- that could help boost the fledgling fuel-cell industry. Their report appears in the journal ACS Nano.
Researchers from the Naval Research Laboratory use gated digital holography methods to develop foliage penetrating LiDAR that can survey obscured ground.
While the Federal Motor Carrier Safety Administration's (FMCSA) Safety Measurement System (SMS) used to identify commercial motor vehicle carriers at high risk for future crashes is conceptually sound, several features of its implementation need improvement, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.
High-strength, lightweight steels can finally be processed on an industrial scale, thanks to a breakthrough in controlling undesired brittle stages from production, by WMG, University of Warwick.
Researchers at the University of Waterloo have developed a system for service vehicles that could reduce emissions and save companies and governments millions of dollars per year in fuel costs.
Electrical engineers have invented a printed sensor made of metallic carbon nanotubes that can monitor the tread of tires in real-time. In its first demonstration, the cheap, simple innovation shows it can measure tire thickness down to the millimeter while surviving the harsh conditions of the interior of a tire.
