This study systematically evaluates heavy metal contamination in liquid foundation products using inductively coupled plasma mass spectrometry, with particular attention to thallium, a highly toxic neurotoxic metal. Most detected substances remained within the limits specified by China’s Safety and Technical Standards for Cosmetics (2015). However, thallium concentrations in two product batches exceeded the reference limits. Further source analysis showed a notably high thallium detection rate in samples containing zinc oxide, suggesting contamination during zinc oxide production. The findings highlight the need for stricter raw material control, improved thallium removal technologies, independent testing, and more refined safety standards for vulnerable populations.

A research team has revealed how geographical conditions and local micro-environments jointly regulate nitrogen removal in a forest-dominated river, with the dominant controls shifting between seasons. 

A research team has found that finely ground coconut-shell biochar can simultaneously increase carbon dioxide (CO₂) uptake and improve the mechanical performance of natural hydraulic lime (NHL). 

The release of marine isoprene is an important component of material exchange between the ocean and the atmosphere, and its long-term variability and climatic drivers have attracted widespread attention. A research team led by Professor Jialei Zhu at Tianjin University constructed a global marine isoprene emission flux dataset spanning 1950–2020 using machine learning and an improved parameterization scheme. Basing on this dataset, they have revealed mechanisms through which the El Niño–Southern Oscillation (ENSO) modulates the interannual variability of marine isoprene emissions by influencing sea surface temperature, solar radiation, surface winds, phytoplankton activity, and other environmental factors. This study has been published in 2026 Chinese and English editions of SCIENCE CHINA Earth Sciences.

A multi-institutional research team reviews progress in CO₂-involved organic synthesis over the past five years. By organizing reactions according to C-C, C-N, and C-O bond formation, the review highlights the growing role of photochemistry and electrochemistry in converting CO₂ into value-added organic products.

A recent study by Lanzhou University's Center for Pan-Third Pole Environment has revealed a climate-sensitive, multi-sphere bacterial metacommunity on the Tibetan Plateau, reshaping our understanding of microbial connectivity across alpine ecosystems. Analyzing 3,373 samples from five habitats, the team identified precipitation as a key driver with dual effects—homogenizing most ecosystems while enhancing microbial uniqueness in glaciers. The breakthrough calls for integrating microbial monitoring into plateau ecological security assessments.

A synthesis of ground surveys across Southwest China finds that soil thickness explains nearly 70% of the spatial variation in woody vegetation growth potential, far more than climate or soil nutrient concentrations. Below a 57.5-centimeter threshold, limited soil volume becomes the dominant constraint, where vegetation becomes less related to soil nutrient concentrations and more closely associated with climate variability.

Electroencephalography (EEG) foundation models are emerging as a promising approach for brain-computer interfaces, but their generalization ability remains unclear. Researchers developed EEG-FM-Compass, a benchmark reviewing 55 EEG foundation models and evaluating 12 open-source models across 13 datasets and nine brain-computer interface paradigms. The study shows that current models have transfer potential but require task-specific adaptation, while specialized models remain competitive and larger models do not necessarily generalize better.

The researchers demonstrate ultra-effective growths of archetypal metastable correlated-perovskites, e.g. nickelates (RENiO₃), via liquid phase epitaxy within alkali-chlorides molten-salts, realizing micrometer-thickness and scalability. This bridges technological-discontinuities in micrometer-thick film-growths of RENiO₃, achieving record-competing electronic phase transitions at analog-compatible resistances enabling more effective and energy-efficient analog cryogenic alarming applications. Wafer-scale RENiO₃ with high-uniformity was firstly successfully grown within low melting-point eutectic alkali-chlorides, eliminating previous reliance on MPa-high oxygen-pressures. This strategy was extendable to multiple functional oxide-systems.
