Modern technologies face overlapping challenges from electromagnetic interference, fire risk, heat buildup, and noise. Researchers developed a lightweight, bio-based aerogel to address these issues simultaneously. Using cellulose combined with metal–organic frameworks (MOFs) and controlled carbonization, they created a porous material that absorbs microwaves, reduces flammability, insulates heat, and dampens sound. The multifunctional performance is achieved with low filler content, demonstrating a sustainable strategy for advanced protective materials across multiple demanding applications.

This groundbreaking integrative taxonomic study reveals that a single described ant species in Australia’s monsoonal tropics actually comprises at least 26 genetically and morphologically distinct species, with estimates suggesting the complex contains over 50 species total, challenging long-held assumptions about global ant diversity hotspots.

Applying beneficial microbes to soil sounds simple, but in practice it can be difficult to distribute small amounts of microbial products evenly through growing media or field soils. A study published in Biochar suggests that carefully selected biochar could help solve this problem.

A global analysis suggests that biochar, a charcoal-like material made from biomass, could play a larger role in climate-smart agriculture when it is applied according to local soil and climate conditions. The study, published in Biochar, combines global meta-analysis, machine learning, and density functional theory calculations to identify how different biochar types and application rates can help reduce greenhouse gas emissions from croplands while improving crop yields.

Wastewater treatment plants are key to global carbon neutrality efforts. A new study in Engineering shares a clear, science-based roadmap to cut emissions and energy use in these facilities. It covers smarter operation, low-carbon technologies, greenhouse gas control, energy from sludge and effluent heat, and turning wastewater into valuable resources. This practical guide shows how to make wastewater treatment sustainable without losing treatment quality.

This comprehensive study details Nanjing Botanical Garden Mem. Sun Yat-sen’s remarkable achievements in plant germplasm collection, endangered species protection, and industrial resource development, providing valuable insights for China’s emerging national botanical garden system.

As the world searches for practical ways to reduce carbon dioxide emissions, scientists are developing catalysts that can transform CO2 from a climate concern into a useful industrial resource. A study published in Biochar reports a coconut shell-derived biochar catalyst that efficiently converts CO2 into carbon monoxide, an important building block for producing fuels, chemicals, methanol, olefins, and polymers.

Researchers have developed a light-driven catalyst made from two common waste materials, discarded PET plastic bottles and orange peels, that can efficiently break down acetaminophen in water. The study, published in Biochar, presents a sustainable strategy that links plastic upcycling with advanced water treatment.
