A pilot study finds that large mammals are more likely to use wildlife crossing structures than move past a random location in the surrounding habitat. Animal movement also varied between crossing structures in different locations, suggesting that location might be more important than design. These findings are a first step towards a better understanding of the effectiveness of wildlife crossing structures.
A solid median, wide shoulders, minimal hills -- and a high speed limit? Brigham Young University researchers explore freeway features that minimize crash risk.
Many researchers know that new high-efficiency buildings don't typically get used as intended. The numbers don't add up, and occupants can easily waste energy if they do not understand how to use the building. Julia Day, assistant professor in Washington State University's School of Design and Construction, set out to learn why.
Engineers at MIT and Tufts can make a material that is stiffer than the real thing. Starting with silk produced by silkworms, breaking it down chemically, and then reassembling it, the new material can be shaped into complex structures such as meshes and lattices.
An international team of researchers has developed a new light-based manipulation method that could one day be used to mass produce electronic components for smartphones, computers and other devices.
Heat transport through pillared graphene could be made faster by manipulating the junctions between sheets of graphene and the nanotubes that connect them, according to Rice University researchers.
The catastrophic 2017 hurricane season provided ample demonstrations of the vulnerability of populations and infrastructure in coastal areas to natural disasters. A new study by scientists at UC Santa Cruz and the University of Cantabria, Spain, identifies hotspots of coastal risks throughout Latin America and the Caribbean.
Countdown timers that let motorists know when a traffic light will go from green to yellow lead to safer responses from drivers, research suggests.
With the successful test of this solar reactor design, Denk has achieved the first step, creating H2O on the Moon using solar thermal energy. For the second step, solar electrolysis would break the H2O into hydrogen and oxygen.
Russian researchers proposed sensors capable of operating at room temperature. Their new nanocomposite sensors are based on zinc and indium oxides, and their efficiency is maximized by green light illumination. The proposed device could be used to detect combustible, explosive, or poisonous substances in the atmosphere even at low concentrations.
