(0:42) - : Electronic Nose:

Pharmaceutical manufacturers are in need of a system capable of distinguishing different types of mint and researchers at Karlsruhe Institute of Technology believe their newly developed artificial nose could be the answer. The system uses changes in resonance of a quartz crystal and a machine learning algorithm to distinguish between various mints with high specificity. 

(6:15) - Wastewater Energy Harvesting:

Microbial fuel cells have been around for quite some time and their purpose is simple: turn the organic waste into bioelectricity. Professor Zhen He at Washington University in St. Louis decided to build on this platform and developed a fuel cell that can generate electricity while filtering water.

(12:35) - Farm Monitoring From Space:

Droughts can be disastrous for farmers and drought insurance is a tool that can help alleviate some of that burden; however, it is often riddled with bureaucracy and having to wait until your crops fail before a payout. Newly published research from ETH Zurich suggests that monitoring crops via satellites and creating insurance policies that payout automatically in response to real-time changes of drought parameters could be the future of agriculture.
