But many heavy metals and other inorganic pollutants form negatively-charged ions in water, and existing water treatment processes to remove them are inefficient and expensive. Chemists have now developed a new type of material that can soak up negatively-charged pollutants from water.

Such data can deplete precious storage space, bog down the system's efficiency and sap its energy. Computer scientists now propose adapting a real-world approach to the cleanup effort.

A recent study traces the ways in which humans are the principal agents of dispersal of exotic earthworms in the forests of Northern America. Their findings suggest that humans spread earthworms both inadvertently via horticulture and land disturbance, in the tires and underbodies of vehicles, but also knowingly through composting and careless disposal of fish bait.
