A team in Erlangen used functionalized iron oxide nanoparticles to bind a broad range of PFAS and fluorine-containing microplastics, then remove them with a magnet. In tests on river water, laundry wastewater and a contaminated drinking water source, PFAS fell by 87%, below Germany’s 100 nanograms per liter limit.

A team in Erlangen used functionalized iron oxide nanoparticles to bind a broad range of PFAS and fluorine-containing microplastics, then remove them with a magnet. In tests on river water, laundry wastewater and a contaminated drinking water source, PFAS fell by 87%, below Germany’s 100 nanograms per liter limit.

Brazil’s federal police are using forensic “gold fingerprinting” to compare seized gold with samples from protected areas and Indigenous lands. The method can help prove illegal origin, support prosecutions and strengthen oversight of supply chains linked to Amazon deforestation and mercury pollution.

Solar panels generated a record 52 TWh of electricity across the European Union in June, supplying 25% of the bloc’s power for the first time. Solar outpaced nuclear, gas, wind and hydropower as installations continued to expand, with 18 countries setting new records for their share of solar generation in 2026.
