Townsend-Small, an assistant professor in UC's College of Arts and Sciences, has been studying methane leaks in the petrochemical industry from Ohio to California. While natural gas burns cleaner than coal, it has one serious drawback: methane that leaks from transport and extraction, Grist reported.
Knowing how much methane seeps out of the ground at wells or from pipelines can help policymakers understand the untold impact that natural gas has on greenhouse gas emissions, Grist reported.
“That sort of catalyzed a giant push for more research on methane emissions across the whole supply chain,” Townsend-Small told Grist.
In a 2018 study in the journal Science, Townsend-Small found that more than 2 percent of natural gas extracted in the United States escaped into the atmosphere or groundwater. This was far higher than estimates compiled at the time by federal regulators.
And Townsend-Small found many sources of leaks belong to wells long abandoned by responsible parties.
“If you want to make a big impact, you only have to fix the big leakers,” Townsend-Small told Grist.

App turns smartwatch into detector of structural heart disease

An app that uses an AI model to read a single-lead ECG from a smartwatch can detect structural heart disease, researchers reported at the 2025 Scientific Sessions of the American Heart Association. Although the technology requires further validation, researchers said it could help improve the identification of patients with heart failure, valvular conditions and left ventricular hypertrophy before they become symptomatic, which could improve the prognosis for people with these conditions.
