How mosquitoes got their taste for human blood and what it means for the future

Of about 3,500 mosquito species around the world, only a few have taken to specifically targeting people for biting, making them important spreaders of infectious diseases. To predict and help control the spread of those mosquito-borne illnesses, it’s important to…

Homes of wealthy Americans have carbon footprints 25% higher than lower-income residences

The homes of wealthy Americans generate about 25% more greenhouse gases than residences in lower-income neighborhoods, mainly due to their larger size. In the nation’s most affluent suburbs, those emissions can be as much as 15 times higher than in…

Air conditioner bumps the electric bill by 42%, increasing the risk of energy poverty

A new study published in Economic Modelling by researchers at Ca’ Foscari University and CMCC shows that owning and using an Air Conditioner greatly increases the electricity bills of households, with important implications for the energy poverty of the less…

Nanoparticles can make home refrigeration more accessible for low-income households

Power consumption of a home refrigerator can be cut by 29% while improving cooling capacity. Researchers replaced widely-used, but environmentally unfriendly, R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotube (MWCNT) nanoparticles. Drop-in refrigerant replacement…

RIHN taking initiative on discussion toward ‘new life’ after COVID-19 pandemic

The initiative of Covid-19 and Sustainable Transitions was inspired by a blog by the leadership of the Systems of Sustainable Consumption and Production Knowledge-Action Network and began in late-March in the form of an interactive online Open Forum, which has…

A scalable method of diagnosing HVAC sensor faults in smart buildings

Heating, ventilation and air-conditioning (HVAC) systems are the biggest consumers of energy in a building. For smart buildings, technologies have evolved to improve energy efficiency of HVAC systems, but faults often occur. Due to the complex nature of large-scale HVAC…
