Cleaner cooking: Sawdust briquettes show promise over charcoal

Biochar Editorial Office, Shenyang Agricultural University

A recent study offers new insight into the air quality and health benefits of switching household cooking fuels from charcoal to biofuel briquettes made from sawdust. Published in Carbon Research, the comparative assessment led by Junior Maimou Nganko and collaborators examines the emissions of harmful pollutants from these popular fuels and their implications for domestic energy choices in Africa and other developing regions.

Why restoring vegetation can both store and lose carbon in soils

Biochar Editorial Office, Shenyang Agricultural University

Restoring vegetation is widely promoted as a natural way to fight climate change, but new research shows that its effects on soil carbon are not always straightforward. A study published in Carbon Research by scientists Lei Deng and Zhouping Shangguan from Northwest A&F University, China, reveals that soil organic carbon (SOC) can either rise or fall in the early stages of vegetation restoration, depending largely on the soil’s initial carbon content.

How can (A)I help you?

University of Texas at Austin
Peer-Reviewed Publication

A new study by Yifan Yu, a Texas McCombs assistant professor of information, risk, and operations management, offers companies guidance on how to balance the promise and perils of AI for customer care.

With McCombs postdoctoral researcher Wendao Xue, he analyzes AI systems that detect human emotions — so-called emotion AI — and how companies might deploy them in various kinds of scenarios.

Straw-based biochar and smart irrigation help maize thrive with less water and fertilizer

Biochar Editorial Office, Shenyang Agricultural University
Peer-Reviewed Publication

A new study has revealed that the lasting effects of biochar depend strongly on the material it is made from, with straw-derived biochar offering clear advantages for maize productivity under limited-water conditions. The research, published in Biochar, shows that combining wheat-straw biochar with an alternate partial root-zone drying irrigation system can boost crop yield and resource efficiency for at least two growing seasons after a single biochar application.

AI ECG better detects severe heart attacks in emergency setting

American College of Cardiology
Peer-Reviewed Publication

Using artificial intelligence (AI) to analyze electrocardiograms (ECG) improved detection of severe heart attacks, including those that presented with unconventional symptoms, or atypical ECG patterns, and reduced false positives, according to a study published in JACC: Cardiovascular Interventions and simultaneously presented at TCT 2025 in San Francisco.

Dirty water boosts prospects for clean hydrogen

Princeton University, Engineering School
Peer-Reviewed Publication

Wastewater can replace clean water as a source for hydrogen, eliminating a major drawback to hydrogen fuel and reducing water treatment costs of hydrogen production by up to 47%, according to new research from Princeton Engineering.
