Plastic-Degrading Enzyme
Eight million metric tons of plastic waste, including polyethylene terephthalate (PET) bottles, enter the oceans each year, creating huge manmade islands of garbage. Experts estimate that by 2050, there will be as much waste plastic in the ocean by mass as there are fish. A bacterium, Ideonella sakaiensis 201-F6, can...

Self-Healing, Fluid-Inspired Material
Even tiny cracks can cause bridges to collapse, pipelines to rupture, and fuselages to detach from airplanes due to hard-to-detect corrosion in tiny cracks, scratches, and dents. A new coating strategy for metal self-heals within seconds when scratched, scraped, or cracked. The novel material could prevent...
