A UCLA study found a connection between how quickly the brain ages and the bacteria and chemical byproducts found in the gut, offering a fresh clue into what drives brain aging long before symptoms appear.
A Reusable Catalyst for Antibiotic Removal
Sulfamethoxazole, a widely used antimicrobial, can persist in aquatic environments and pose risks to ecosystems and human health. Researchers led by Xuejiao Tang at Nankai University developed millimeter-scale magnetic carbon beads, designated CoNC@cPAN/rGO-800, to address the limited recoverability and metal-leaching concerns associated with powdered cobalt catalysts. The material combines a polyacrylonitrile carbon framework, reduced graphene oxide, and cobalt-containing active sites.
Porous Structure, Rapid Degradation
The beads were prepared from a cobalt-containing zeolitic imidazolate framework, polyacrylonitrile, and graphene oxide, followed by calcination under nitrogen at different temperatures. Microscopy, spectroscopy, diffraction, surface-area analysis, electrochemical measurements, and density functional theory calculations were used to characterize the material and assess its catalytic behavior. Under optimized conditions, 0.1 g L⁻¹ of catalyst and 0.1 g L⁻¹ of peroxymonosulfate removed 100% of 10 mg L⁻¹ sulfamethoxazole within 20 min at pH 7.
SHEA has published a new practical guide to help healthcare organizations build the business case for diagnostic stewardship. Published in Antimicrobial Stewardship & Healthcare Epidemiology (ASHE), the resource outlines five high-impact interventions and provides implementation strategies and financial models that hospitals can adapt to their own settings. The authors estimate that a representative 200-bed community hospital implementing all five interventions could realize approximately $2.5–$2.8 million in annual laboratory and clinical savings, with additional potential savings through improved quality metrics and reduced CMS penalties. The guide, developed by SHEA’s Diagnostic Stewardship Special Interest Group, demonstrates how diagnostic stewardship can simultaneously improve patient care, healthcare quality, and operational performance.
A Changing Carbon Balance
Soil organic carbon supports soil health, water retention, nutrient cycling, soil structure, and microbial diversity. A review led by Nanthi Bolan examines how climate change-induced droughts, floods, and wildfires can alter these functions by changing carbon inputs, decomposition, erosion, and the movement of dissolved organic carbon.
The analysis places soil carbon within the wider climate system. Depending on environmental conditions and land management, soils can either store carbon or contribute to greenhouse-gas emissions. The authors argue that protecting soil carbon is important not only for climate mitigation but also for sustaining agricultural productivity and ecosystem services.
Mapping the Evidence
On 14 January 2026, the authors searched Google Scholar, PubMed, and Web of Science using terms related to climate change, extreme weather, soil carbon, microbial activity, decomposition, erosion, dissolved organic matter, and leaching. The initial search produced 14,218 records. After duplicate removal and eligibility screening, 3,754 articles were retained for bibliometric and qualitative analysis.
A new study published in The Lancet Public Health assessed candy and soda sales in supermarkets, drug stores, and mass-market retailers in Berkeley, as well as three comparison cities in California, after a first-of-its-kind healthy checkout ordinance was implemented in 2021 and then became enforceable in 2022. Changes in sales varied by product and store type: soda sales decreased substantially after the HCO was implemented and enforced, while sales of small-packaged candy decreased significantly in supermarkets after the HCO was enforced. Overall candy sales increased moderately after the policy was implemented (but not after enforcement), but so did sales in healthy, lower-sugar items such as snack-sized nuts and seeds. Supermarkets, which complied the most with the HCO, saw the greatest declines in sales of these sugary items, while drug stores, which complied the least, did not have reduced candy or soda sales.
