The Agricultural non-CO₂ Greenhouse gAs InveNtory (AGAIN) is a bottom-up model following the Tier 2 methodology of the IPCC to estimate emission trajectories and evaluate the mitigation potential of China’s agricultural non-CO₂ greenhouse gas (GHG) emissions at the provincial level through 2060 under four scenarios: business-as-usual (BAU), current policy (CP), conventional technical potential (CTP), and maximum technical potential (MTP). The model covers six agricultural subsectors, including freshwater aquaculture, and incorporates eight policy objectives and seventeen agricultural mitigation technologies within its scenario module. It can identify priority mitigation regions and sectors under different scenarios.

As AI—and the ethical debate surrounding it—accelerates, scientists argue that understanding consciousness is now more urgent than ever. Researchers writing in Frontiers in Science warn that advances in AI and neurotechnology are outpacing our understanding of consciousness—with potentially serious ethical consequences.

A new study suggests screenings to identify children who struggle to learn to read may not work as intended in all schools: Many teachers did not receive adequate training to perform the tests, and about half reported they were not confident children who need extra instruction in reading end up receiving it.

Investigators at Mass General Brigham and the Richard A. and Susan F. Smith Center for Outcomes Research at Beth Israel Deaconess Medical Center have found that international doctors sponsored by H1-B visas in 2024 comprised nearly 1% of the entire physician workforce in the United States, with substantial variation in different counties’ reliance on H-1B-sponsored physicians and other healthcare professionals. The research, published in JAMA, comes out just weeks after a presidential proclamation that substantially increased employers’ fees for H1-B visa applications.
