Understanding the Ecological Consequences of Increasing Global Night Sky Brightness

Over the past decade, the night sky has brightened by an average of nearly 10 percent per year. According to projections, by 2052, half of the Earth's land area will be affected by light pollution.

Stricter Air Standards Accelerate Progress Toward WHO 2040 Target

China introduced a 35 µg m-3 annual PM2.5 limit in 2012 and later cut population-weighted exposure from 62.8 to 29.7 µg m-3 between 2013 and 2024 through clean air actions.

Aerobic Sulfate Reduction in Plant Roots Enables Sustainable Metal Upcycling

Conventional physical and chemical treatments can remove over 90% of heavy metals, but they often require energy-intensive steps and can generate secondary pollution. Phytoremediation is greener, yet plants mainly store metals in biomass, creating hazardous waste rather than recoverable products. Microbial biomineralization can make valuable metal sulfide nanomaterials, but many high-performing sulfide-producing microbes are sulfate-reducing bacteria that grow slowly and are inhibited by oxygen, including oxygen released from plant roots.
