Scientists have solved one of the mysteries of certain soil bacteria that allows them to persist without an apparent source of sustenance. It might lead to solutions for improving agricultural production while reducing greenhouse gas emissions.

Amid growing demand for seafood, gas and other resources drawn from the world’s oceans, and growing stresses from climate change, we examine some of the challenges and solutions for developing “the blue economy” in smarter, more sustainable ways.
