According to a new study, the resurgence of aquatic grasses in Chesapeake Bay is the result of decades of efforts to reduce nutrient pollution.

Drone delivery is expected to take off big time in the next few years.  Chinese online retailer JD.com has already launched drone delivery in four provinces in China, while DHL and Zipline are delivering medicines with drones in rural and hard-to-reach areas. Amazon, Google, and UPS are all working on getting drone delivery service off the ground. 

There are a lot of issues to think about when it comes to package delivery using drones—safety, privacy, and logistics being some of the main concerns. In a new study, researchers tackle two other important aspects: energy use and greenhouse gas emissions.

Across the globe, billions of dollars are spent annually on repairing ecosystems damaged by people. Forests denuded by logging. Rivers polluted by industry. Grasslands converted to agriculture.

That could mean up to a $46 million boost to the county’s economy in just one summer.

Global levels of ethane and propane in the atmosphere have been underestimated by more than 50%, new research involving scientists at the University of York has revealed.
