A new device that can reduce the intensity of sound passing through open windows is presented in a proof-of-principle study in Scientific Reports. It fits into a two-panel sliding window and can decrease the perceived loudness of urban transportation noises by up to half (10 decibel reduction).
The COVID-19 pandemic has thrust the world into turmoil and disrupted the status quo, but it is also providing opportunities for innovation in the way we live and work. According to the latest report released by The World in 2050 (TWI2050) initiative, the crisis can provide an opportunity to create sustainable societies with higher levels of well-being for all.
Short, frequent walks in blue spaces--areas that prominently feature water, such as beaches, lakes, rivers or fountains -- may have a positive effect on people's well-being and mood, according to a new study led by the Barcelona Institute for Global Health (ISGlobal) and published in Environmental Research.
Real-world mobile phone data suggests a decline in the number of trips people made per day began before state-level stay-at-home policies were implemented, and the decline was strongly correlated with a reduction of COVID-19 case growth in the 25 most affected counties across the USA, according to a modelling study published in The Lancet Infectious Diseases journal.
Artificial light at night attracts insects, thus giving invasive cane toads in places like Australia a lot more food to eat, researchers have found, potentially giving a boost to such invasions.
Modeling shows that coral reefs off the east coast of Saudi Arabia have a vital role in protecting the coastal zone.
In a simulation, drones were able to hitch rides on public transit vehicles to save energy and increase flight range. An algorithm decided which drones should make which deliveries, one package at a time, in what order -- and when to fly versus hitching a ride.
Access to green spaces in metro areas--parks, trails, even the tree cover in a neighborhood - is largely associated with income and race, new research indicates. Researchers combined census-block-group demographic and socio-economic data with satellite imagery to analyze access to green spaces and vegetation in two metropolitan areas: Columbus, Ohio, and Atlanta, Georgia. Their study appears in the August issue of the journal Landscape and Urban Planning.
A study by Bangor University and the University of Plymouth shows the presence of artificial light originating from cities several kilometres away (also known as artificial skyglow) disrupts the lunar compass species use when covering long distances.
Today's modern cities, from Denver to Dubai, could learn a thing or two from the ancient Pueblo communities that once stretched across the southwestern United States. For starters, the more people live together, the better the living standards.
