The Silk Leaf, by RCA graduate Julian Melchiorri, is the first manmade material that can perform photosynthesis. It has huge implications for science and technology and it could also make long-distance space travel a possibility.

The Coca-Cola Bottling Company in Needham Heights, Mass., has removed about 98 percent of influent biological oxygen demand (BOD) after installing a BioprocessH2O membrane biological reactor (MBR) system, according to a Bioprocess H2O case study.

The Urban Algae Folly gazebo at Expo 2015 in Milan, Italy, is covered in algae-filled ethylene tetrafluoroethylene plastic that may herald the future of green building. The spirulina in the plastic membranes absorbs carbon dioxide and produces oxygen while expanding more as sunlight intensifies to provide shade. 

Naturally occurring climate change lowered oxygen levels in the deep ocean, decimating a broad spectrum of seafloor life that took some 1,000 years to recover, according to a study that offers a potential window into the effects of modern warming.

Researchers at Royal Melbourne Institute of Technology in Australia have developed solar paint containing a moisture-absorbing compound that also is able to split water into oxygen and hydrogen. If water vapor is in the air, then any surface painted with this product can produce hydrogen fuel, researchers said, regardless of the location or climate.
