Urban pollutants are a health concern in growing cities. Scientists are turning to honey bees to help monitor contaminants in soil, water, air and plants.
Until the recent observation of merging neutron stars, how the heaviest elements come to be was a mystery. But their fingerprints are all over this cosmic collision.
Ordinary grey bird feathers placed under X-ray fluorescence reveal beautiful patterns of elements like zinc, telling a story of feather growth and the environments the birds have experienced.
