Evidence of global relevance

Environmental trade-offs of biogas utilization pathways: a global life cycle synthesis with policy-relevant insights for Southeast Asia

The systematic review synthesised 28 peer-reviewed life-cycle assessment studies published from 2015 to 2025. It compared direct combustion, combined heat and power, biomethane upgrading, transport use and carbon capture and utilisation. Results were standardised to one megajoule of useful energy and assessed across climate, eutrophication, acidification, particulate matter and resource-use indicators.

Infectious Disease Surveillance72IMPACT SIGNAL
National surveillance evidence

Japan's invasive meningococcal cases fell to one during COVID-19, then rebounded to 68 in 2025

Japan's national surveillance from January 2017 to October 2025 identified 288 IMD cases across pre-pandemic, pandemic and reopening phases. Cases fell from 48 in 2019 to one in 2021, then rose to 66 in 2024 and 68 by October 2025. Older adults consistently accounted for the most cases, adolescents clearly rebounded, and Tokyo rose more than Osaka/Kansai. No Expo-specific surge appeared. Cases and inbound travel had Spearman rho 1.000, although most infections were domestically acquired.

Laboratory mechanical prototype

RaLak titanium lattices tune stiffness and energy absorption to better mimic bone

Solid metallic implants are much stiffer than bone and can cause stress shielding. A Ti6Al4V bio-inspired lattice called RaLak was laser-powder-bed-fused at 20% and 30% relative density and 2-4-mm cells and compared with gyroid and diamond TPMS. RaLak improved the stiffness-energy-absorption balance; at 30% density and 4-mm cells it absorbed about 50% more energy than gyroid. Its hybrid architecture promoted uniform stress and progressive deformation, and modified Gibson-Ashby models linked geometry to response.

Behavioral experimental evidence

Two experiments suggest GenAI can reduce overload in sustainable travel choices

Two experiments covered trip planning and on-site shopping to test whether GenAI helps users navigate abundant eco-certified options. More advanced tools reduced perceived information overload and improved decision-making. Greater trust related to well-being and intention to use GenAI, while lower perceived decision risk also related to intention. The authors report more eco-responsible choices, but the abstract does not clarify whether behavior was consequential or self-reported.

Systematic review and meta-analysis

Implant-supported prostheses produced stronger functional gains for older adults with tooth loss

From 7,654 records, 24 studies with 1,711 adults aged at least 65 and prosthesis use for six months were included. Fourteen studies assessed mastication and bite force. Complete dentures gave modest gains, while implant overdentures produced higher performance and bite force with more consistent long-term improvement. Across 18 PROM studies, implant overdentures and fixed full-arch prostheses produced the largest oral-health quality-of-life gains; complete and removable partial dentures had smaller positive changes. Subjective chewing improved over 6-12 months with high heterogeneity.

Regional scoping-review evidence

Heat raises health risks across ASEAN, while heatwave definitions and geographic evidence remain fragmented

This scoping review included 76 Southeast Asian studies published since 2000: 28 mortality, 38 morbidity and 10 effect-modification studies. Minimum-risk temperatures and thresholds varied widely by location and outcome. Reported relative risks ranged from 1.02 for all-cause admission in Vietnam to 4.21 for dengue in Laos, but these outcomes are not directly comparable. Relationships were often nonlinear, evidence for heat-air pollution synergy was mixed, immediate effects were stronger for NCDs, and some dengue studies reported long lags.

Biopolymer Films and Packaging72IMPACT SIGNAL
Laboratory materials evidence

Calcium alginate powder increased thermo-compressed sodium-alginate film strength by 208%

Seaweed-derived alginate is biodegradable and biocompatible, but sodium-alginate films are mechanically weak. With glycerol plasticizer, calcium-alginate powder at 2.5-20 wt% was added before thermo-compression. SEM/EDS indicated good interfaces and moisture declined with CA content. At 20 wt%, tensile strength reached 11.7 MPa and modulus 234.7 MPa, increases of 208% and 907% over unfilled SA, showing effective reinforcement by an ionically distinct alginate filler.

Pilot-scale energy evidence

Pilot vibrating torrefaction upgraded Thai rubberwood and corn wastes to 22.4-MJ/kg fuel pellets

A pilot vibrating torrefaction system processed rubberwood- and corn-waste pellets at 220-300°C for 16 or 30 minutes. Greater severity increased HHV to 22.4 MJ/kg, about 20% above raw pellets, and improved grindability and moisture resistance, while mass and energy yields declined. Specific electricity use was 624-1,161 kWh per product tonne and preliminary cost THB 8,000-11,000/t including capital, feedstock and electricity, demonstrating both technical feasibility and economic tradeoffs.

Long-run econometric evidence

India's 1969-2023 data link nuclear energy and human capital with lower ecological pressure

The study integrates CO2 emissions, ecological footprint and load-capacity factor to represent emissions, resource demand and regenerative capacity in India. Annual 1969-2023 data were analyzed with ARDL bounds testing and robustness estimators including FMOLS, DOLS and canonical cointegration regression. Results supported Environmental Kuznets and Load Capacity curves. Nuclear energy and human capital were associated with improved long-run environmental performance, while economic growth and natural-gas consumption were associated with greater pressure.

Mechanisms and applications review

Postbiotics may be more stable than probiotics, but health evidence must remain product specific

Postbiotics are preparations of inanimate microorganisms and/or components conferring a health benefit, while paraprobiotics often refer to inactivated cells. The review covers cell-wall fragments, metabolites and signaling molecules, proposed barrier, immune and microbiome mechanisms, and human and animal nutrition applications. Stability, storage and risks associated with live organisms may improve over probiotics, but heterogeneous strains and processing prevent class-wide efficacy claims.

Laboratory pyrolysis evidence

Pyrolysis converted waste-cooking-oil sludge into fuel fractions and biochar

Sludge from waste-cooking-oil pretreatment for biodiesel is organic-rich but low value. Pyrolysis separated it into liquid, gas and carbon-rich solid. Light, middle and heavy liquid cuts had higher heating values of 44.3-44.6 MJ/kg, while gas reached a 53.6 MJ/Nm3 Wobbe Index suitable for thermal applications. Higher temperature shifted yield from liquid to gas. Biochar retained energy and carbon-storage potential, but salinity and alkali constrain land use.

Functional Beverages72IMPACT SIGNAL
Food process and formulation evidence

Pectinase optimization prioritized bioactive recovery before developing a three-fruit beverage

Date juice was extracted with 0.1% pectinase at 50-80°C for 60-240 minutes. Fifty degrees for 60 minutes was selected for functional quality, yielding 326.33 mg GAE/100 mL phenolics, 1.08 mg beta-carotene equivalents/100 mL carotenoids and strong DPPH/FRAP activity, although maximum 81.25% yield occurred at 60°C for 240 minutes. Six simplex-lattice beverage blends were developed; the 70% date and 15% each of two companion fruits scored highest at 6.50. All blends improved measured bioactives versus control with stable pH and acidity.

Laboratory electrolyte evidence

Alginate-lignin raised ionic conductivity in a biobased gel electrolyte by nearly fourteenfold

A green gel polymer electrolyte combining sodium alginate, lignin and Na2SO4 was compositionally optimized. Conductivity reached 2.91×10^-4 S/cm versus 2.09×10^-5 S/cm in the baseline, about a 13.9-fold increase. Dielectric and electric-modulus analysis indicated shorter relaxation and improved carrier dynamics, ionic transference reached 0.98, and the stability window reached 2.85 V. Excess salt caused ion association and reduced transport.
