Yale researchers have found that agricultural "liming" — the long-standing practice of adding limestone to farm fields — stores more carbon dioxide than it releases, a finding that contradicts conventional emissions accounting.
For generations, farmers in the Mississippi River Basin have added limestone to their fields to replenish soil. The new Yale study identifies an additional climate benefit from the practice.
The finding challenges how emissions from the practice have previously been counted, according to the university.
The research was among several Yale projects highlighted in the September 24, 2026 edition of Yale Today, which also featured the university's "core facilities" — specialized research labs that provide scientists across a range of fields with access to advanced instruments, services and expertise.
"We're scientists who help other scientists do their research," said Guilin Wang, director of one such lab on Yale West Campus.
In a separate Q&A, Yale's Christine Rodriguez discussed the place of artificial intelligence in health care and where human expertise remains essential.
"[W]hen we rely on AI to be moral, when we rely on AI to speak to the lived experience of us as human beings, that is where AI fails," Rodriguez said.
The newsletter also noted that the Yale Peabody Museum's newly upgraded online collections portal draws on the university's LUX platform to make its 14 million objects — most of them rarely or never on public view — accessible to everyone, everywhere.
