It may seem off-putting to some, but human waste is full of nutrients that can be recycled into valuable products that could promote agricultural sustainability and better economic independence for some developing countries, says a new study by University of Illinois researchers.
This work presents an extensive characterisation of materials and components used in non-structural masonry constructions in the region of Pernambuco, Brazil.
Rice University engineers are developing ionic water-treatment technology that saves money and energy by selectively removing only hazardous contaminants and ignoring those that are harmless. The platform technology could be used to treat drinking water and wastewater from industrial applications like oil and gas wells.
What forces enable trees to stand upright? To grow straight, plants need a motor system that controls their posture by generating forces to offset gravity. Scientists have long thought that this motor force was controlled only by the internal forces induced in wood. In a study published on Aug. 4 in New Phytologist, researchers from the CNRS and Cirad show that bark is also involved in the generation of mechanical stresses in several tree species.
Cooking oil and similar waste can clog pipes, harm fish and even grow into solid deposits like the 'fatbergs' that recently blocked London's sewage system. But UBC researchers may have found a way to treat these fats, oils and grease -- collectively called FOG -- and turn them into energy.
These are ORNL story tips: residents' shared desire for water security benefits neighborhoods; 3D printed molds for concrete facades promise lower cost, production time; ORNL engineered the edges of structures in 2D crystals; chasing runaway electrons in fusion plasmas; new tools to understand US waterways and identify potential hydropower sites; and better materials for 3D printed permanent magnets could last longer, perform better.
In a study published today in Science Advances, researchers at the University of California, Irvine report that temperatures during droughts have been rising faster than in average climates in recent decades, and they point to concurrent changes in atmospheric water vapor as a driver of the surge.
University of British Columbia engineers have analyzed just how mobile device use affects pedestrians, and their findings could help develop safer roads and autonomous cars in the future.
The North China Plain, a region that holds one of the biggest concentrations of people on Earth, could be pushing against the boundaries of habitability by the latter part of this century due to global warming, an MIT study shows.
Every day, the hundred-mile-long Hong Kong subway system serves nearly five million people commuting from as far away as mainland China. On July 31 in the journal Cell Reports, researchers show how microbes from these diverse travelers mix throughout the day. While each subway line hosts a characteristic set of bacteria during morning rush hour, by evening, these unique bacteria join into one uniform microbiome populating the entire system.
