Some have dreamt of the perfect cloak to make buildings impervious to stress waves caused by bombs, earthquakes or other calamities. Sorry, researchers are now dashing the dream. But there's still hope. They also say it's possible to make imperfect, real-world cloaks that will actually do some good by adding significant partial protection against some common earthquake waves.
A team of WSU researchers has found surprisingly high levels of pollutants, including formaldehyde and possibly mercury, in carefully monitored homes, and that these pollutants vary through the day and increase as temperatures rise.
A group of Italian researchers has developed a method that enables more efficient use of energy by smart homes that are connected to a microgrid -- a web of individualized units that are connected to one another and one common energy source. The findings address the need for efficient approaches to residential energy management by presenting a strategy that controls energy distribution.
A group of scientists in USA has developed the first-ever standardized method of evaluating commercially available driver-monitoring systems. The researchers hope to use their method in a more complex way by incorporating more factors and looking at more scenarios. These include a lighting device that could be used in the lab to simulate real light conditions as well as a few other sites that could enhance the method's accuracy and efficiency even further.
A large-scale program to deliver water filters and portable biomass-burning cookstoves to Rwandan homes reduced the prevalence of reported diarrhea and acute respiratory infection in children under 5 years old by 29% and 25%, respectively. The results suggest that programmatic delivery of household water filters and improved cookstoves can provide a scalable interim solution for rural populations that lack access to safe drinking water and rely on traditional fires for cooking.
Nearly one-fifth of the world's population lives in a stressed water basin where the next climate change-driven incident could threaten access to an essential resource for agriculture, industry and life itself, according to a paper by University of California, Irvine researchers and others, published today in Nature Sustainability.
New research from the University of Pittsburgh's Swanson School of Engineering Mascaro Center for Sustainable Innovation, in partnership with the Kingsley Association and funded by the Heinz Endowments examined the impact that bottom-up, community-level initiatives have in addressing environmental justice issues. They found that the best way to address a community's environmental injustices is to meet them where they are, integrating into the community and building trust over a long-term partnership.
The most comprehensive study of bicycle and road safety to date finds that building safe facilities for cyclists is one of the biggest factors in road safety for everyone. Bicycling infrastructure -- specifically, separated and protected bike lanes -- leads to fewer fatalities and better road-safety outcomes for all road users. New study published in Journal of Transport & Health.
Possible commercial uses are package deliveries since it can quickly fly to a target zone and then drive using its wheels safely and quietly to reach the recipient's doorstep. FSTAR can also be used for search and rescue applications as it can fly over various obstacles and crawl between or underneath cracks where a regular drone cannot fly. The robot can also be used in agriculture, maintenance, cleaning, filming, and entertainment, as well as law enforcement and anti-terrorist applications.
A study by The University of Texas at Austin has quantified the amount of water flowing in major Texas rivers during heavy rains and found that there is enough room in coastal aquifers to store most of it. This discovery means that capturing and storing water could be a feasible option for partially mitigating floods and droughts, which are both expected to increase in frequency and intensity as the climate changes.
