Effectiveness and cost-effectiveness of automated external defibrillators in private homes

JAMA Network
Peer-Reviewed Publication

About The Study: In this study, automated external defibrillators (AEDs) in private homes were effective at improving outcomes for patients with cardiac arrest and a shockable rhythm. Given the relative rarity of cardiac arrest at a given home, general purchase of AEDs for individual private homes cannot be considered cost-effective at the current pricing of AEDs.

A 13-year record indicates differences in the duration and depth of soil carbon accrual among potential bioenergy crops

University of Illinois at Urbana-Champaign Institute for Sustainability, Energy, and Environment

While annual cropping systems such as maize/soy rotation perpetuate soil organic carbon (SOC) loss, perennial crops have been found to contribute to SOC increases. However, most perennial crop studies have been short-term, resulting in incomplete understanding of their long-term impacts on SOC. A new study found that planting perennial crops on land formerly used for annual maize/soy can slow or reverse soil carbon losses, with the greatest increases in soil organic carbon from species-rich prairie.

Rivers of carbon: how land runoff and saltwater shape greenhouse gas emissions at the edge of the sea

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

Now, a new study published on September 22, 2025, in the open-access journal Carbon Research has cracked part of that code. By tracing the journey of dissolved organic matter (DOM) from riverbanks to estuaries, researchers have uncovered how land-based pollution and changing salinity team up to control the release of potent greenhouse gases—carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O).
