A nanoparticle that can help clean water of cadmium becomes toxic once taking in the metal. But research finds that organic matter, in this case from algae, reduces that toxicity.
Attacks on climate policies are not really about the science. They’re about the future of fossil fuels.
Island nations are on the front lines of global climate change. Heavy rainfall and rising sea levels are eroding shorelines and causing flooding.

This initiative seeks to protect coal-fired and nuclear power plants that are struggling to compete with cheaper energy sources.
After remaining steady for three years, global fossil fuel emissions are rising again and may increase again next year. But improved energy efficiency and a booming renewables market may offer a bit of a silver lining.
