Peer-Reviewed Publication

Biochar can help turn agricultural waste into clean hydrogen fuel while cutting carbon pollution, according to a new study in the journal Biochar. Researchers report that a simple two stage catalytic system using corn straw, biochar, and nickel based catalysts more than doubled the hydrogen content of the gas produced during biomass pyrolysis and sharply reduced the carbon deposits that normally deactivate catalysts.

Forecasting the impact of fully automated vehicle adoption on US road traffic injuries

JAMA Network
Peer-Reviewed Publication

About The Study: Commercial autonomous vehicle (AV) availability and adoption are underway and could impact national road traffic injuries. In this simulation study, potential injury reductions in the U.S. were forecasted using several scenarios based on real-world data. The results of this study suggest that AV adoption may reduce expected injuries; however, predicted confidence intervals remain broad for the baseline injury forecast, and none of the scenarios reduced expected injuries outside of these bounds.

Semaglutide and hospitalizations in patients with obesity and established cardiovascular disease

JAMA Network
Peer-Reviewed Publication

About The Study: In this prespecified exploratory analysis of the SELECT randomized clinical trial, the trial cohort had a high rate of hospital admissions. Treatment with once-weekly semaglutide was associated with significant reductions in hospital admissions and overall time spent in hospital, extending its benefits beyond cardiovascular risk reduction.
