Advanced air filter could enable building vents to capture carbon and reduce energy use
Chicago IL (SPX) Nov 12, 2025 Researchers at the University of Chicago Pritzker School of Molecular Engineering have developed a nanofiber air filter designed for building ventilation systems that captures airborne carbon dioxide and could lower household energy costs. The team, led by Assistant Professor Po-Chun Hsu, designed a distributed carbon nanofiber direct air capture filter that transforms residential and commercial HVAC systems into localized carbon-capture sites. The filter operates with over 92 percent efficiency i ... read more |

Biochar type influences greenhouse gas emissions in boreal grasslands
Tokyo, Japan (SPX) Oct 28, 2025 Researchers from the Natural Resources Institute Finland (Luke) and affiliated universities evaluated the climate impact of biochar and hydrochar applications in northern grassland soils. Their controlled study analyzed changes in greenhouse gas emissions, soil carbon pools, and biomass yield after adding either biochar or hydrochar combined with nitrogen fertilizer over three months. The investigation revealed that biochar and hydrochar alter soil chemistry and biology in opposite directions. Bio ... read more
