Antibiotic residues in livestock manure can make waste treatment more difficult and may increase environmental risks linked to antibiotic resistance. Now, researchers have shown that a seaweed-based hydrochar modified with cobalt can help anaerobic digestion systems convert chicken manure containing high levels of sulfadimethazine into more methane while also reducing antibiotic residues and resistance genes.

Agricultural plastics help farmers grow crops more efficiently, but they also create a difficult waste problem when they become tangled with plant residues after harvest. A study published in Biochar suggests that one promising solution may be to convert plastic-contaminated crop waste into biochar, a carbon-rich material that can improve soil quality and help reduce heavy metal risks in contaminated farmland.

After nearly 10 years, three flight experiments and a flying rocket lab, scientists map out the chaotic forces of ultra-fast flight, redefining the future of aerospace travel.

In the paper published on Science of Traditional Chinese Medicine (STCM), the authors employed UPLC-MS/MS technology and elucidated the processing principle of rhubarb pieces based on in vivo profile of components. This study comprehensively analyzed the dynamic in vivo changes of prototype anthraquinones and their glucuronide metabolites in rhubarb from the perspectives of absorption, distribution, and excretion. It proposed that processing can reduce the exposure of components, achieve targeted distribution in the intestine, and accelerate the excretion of components, thereby clarifying the processing mechanism of 'raw rhubarb purges while steamed rhubarb moderates'. This provides a solid research perspective for the study of the processing principles of traditional Chinese medicine.

Scientists have developed a promising material that enables efficient recovery of gold resources from discarded electronic devices.

POSTECH researchers develop a bio-implant with virtually no immune response at the cellular and tissue level.

Small engine maintenance and repair is a topic many agricultural educators are expected to teach. Yet, it remains one of the least emphasized subjects at the post-secondary level. Researchers with the University of Arkansas Division of Agriculture and the Dale Bumpers College of Agricultural, Food and Life Sciences at the University of Arkansas set out to examine instructional strategies to enhance learning quality in small-engine coursework with short-form video self-reflection.
