Amami rabbits show exceptionally delayed maturity in island environment

Okayama University of Science

Using bone‐histology methods typically applied to dinosaurs, researchers found that the endangered Amami rabbit takes approximately five years to reach maturity—about five times longer than closely related rabbits. This extreme growth delay, previously seen only in extinct island mammals, makes this the first known case in a living mammal. The dense, robust bones suggest skeletal adaptation to the island’s steep terrain.

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).
