Researchers made biodegradable films from pectin, glycerol, and purple sweet-potato color that respond to pH changes. The color shift was sensitive and the films could be used to monitor shrimp freshness, based on changes linked to shrimp quality indicators.
A new study using multiple waves of national survey data in China finds that frequent internet use is linked to lower marital stability on average. But the negative link is smaller—or disappears—for people with higher structural resources, while the positive link through well-being grows stronger.
Blue mussels from an Irish hybrid zone responded to repeated heat stress with time-dependent changes in stress-related genes. One key heat-shock gene (hsp24) was strongly induced 24 hours after heat exposure, but expression dropped at later time points. The findings show that how mussels cope with warming may depend on when researchers measure their responses—an issue that matters for managing both wild populations and mussel farming.
This review-style evaluation compares two large language models—OpenAI o1 and DeepSeek R1—in English and Chinese for supporting junior anesthesiologists. Using 30 Delphi-created anesthesia crisis scenarios, experts rated accuracy and logic, while junior physicians rated clarity and usefulness. Results differed: OpenAI o1 scored higher for accuracy, while the DeepSeek R1 Chinese version scored higher for practical, step-by-step guidance.
A new report in European Child & Adolescent Psychiatry describes how webinar training helped build child mental-health skills during the war in Ukraine. The ESCAP-Ukraine initiative reached 10,489 unique participants across the country, including frontline areas, and supported broader efforts to integrate child psychiatry into care and community services.
Early blockage of NMDA receptors in male rats led to long-lasting changes in inhibitory interneurons in the visual cortex, including fewer parvalbumin-positive cells. When the rats later lived in enriched environments, parvalbumin cell counts rose and several plasticity-related protein markers increased, while NMDA receptor NR1 levels did not recover.
Researchers conducted a systematic review and meta-analysis of prospective cohort studies on nut intake and hypertension risk. They found that higher nut consumption was associated with a lower risk of hypertension, including a comparison of the highest versus lowest intake groups. Because the underlying evidence comes from observational studies, the findings show an association, not guaranteed causation.
A new article in the Journal of Ethnic and Migration Studies says that migration labels such as “irregular,” “labour,” and “privileged” don’t stay stable. It argues that people constantly negotiate and contest these categories through everyday experiences, making even the label “migrant” fluid.
A new paper reviews fossil evidence from past “hyperthermals” to understand how rapid warming has repeatedly driven extinctions in both marine and land ecosystems. It argues that modern biodiversity loss could become similarly long-lasting because today’s warming is faster and adds direct human pressures.
Fall armyworm is a major crop pest, and insecticide use is increasingly constrained by resistance and side effects. This review synthesizes evidence that endophytic fungi—fungi that live inside plants—can colonize plant tissues and reduce fall armyworm performance. It also highlights limited field testing and a lack of data on effects on beneficial insects.
A paper in the Journal of Ethnic and Migration Studies argues that the word “human” in migration research carries hidden power claims. Drawing on scholarship about “being human,” the author proposes redefining humans as a mix of biology and shared stories, with multiple valid cultural accounts. The paper also uses a short case study from Cameroon to show how looking differently at “human” can change how migration is understood.
Irradiating contaminated peanuts with gamma rays or an electron beam reduced aflatoxin B1 and microbial contamination. But at higher doses—especially 10 kGy—the treated peanuts showed signs of lipid oxidation and color changes, suggesting a tradeoff between safety and quality.
This systematic review and meta-analysis examined whether lycopene-containing products affect blood vessel function in healthy adults. Among four pooled studies using flow-mediated dilation (FMD), lycopene intake was associated with an increase in FMD. The authors also noted that certainty across studies was limited/moderate and that the overall significance changed after excluding one study.
A new study in the Journal of Ethnic and Migration Studies says Estonia’s asylum system filters refugee claims through official historical narratives. It argues that a shifting idea of “Eastness” influences whether people are seen as close enough to “the West,” and that this ranking can change quickly after major geopolitical events.
China began phasing out electric-vehicle (EV) purchase subsidies in 2018–2019, and the study finds buyers’ decisions shifted toward charging access. In cities with weaker charging networks, adding charging facilities raised EV market share in simulations, while the best subsidy type depended on local infrastructure.
