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...

Printing Ink Removes Oxygen in Sealed Packages
Oxygen adversely impacts food flavor and nutrition. NASA’s proposed five-year shelf life for astronaut food requires aggressive measures to minimize oxygen. Previously, NASA packaged foods in containers with a high oxygen and moisture barrier. These materials have limiting properties. They contain...
