Scientists have uncovered a sponge that can soak up 99% of oil in the freezing Arctic water. The nano-engineered sponge can clean up oil spills as it is covered in a paraffin-like material that helps it work even in frigid-temperature water. NewScientist reported that oil spills happen at a worrying frequency and that in the past, it was difficult to clean up spills in cold water. This is because crude oil’s heavier compounds crystalize in cold water, but the new technology that includes paraffin will be able to work with the crystals. It will create large, sticky masses that will be easier to scoop out than the old clean-up technologies.
