Why the Next Breakthrough in Battery Chemistry Might Come From Studying How Trees Store Energy

Cut a cross-section through a Douglas fir trunk and you are looking at a machine that has been moving and banking energy, without pumping, for a century or more. Materials scientists have started looking at that machine less as a metaphor and more as a blueprint. ONE IDEA A tree’s vascular system solves a problem

Inside the Quiet Redesign of How Cities Manage Their Water

Sensor networks and old infrastructure are an unlikely but increasingly common pairing, and the results are already reshaping how utilities decide where to dig. Most of the pipes carrying drinking water under major cities were laid before anyone thought to make them smart. Some of the cast-iron mains beneath American streets predate the automobile. Retrofitting

What Family-Run Companies Understand About Risk That Public Companies Often Don’t

Every recession produces the same headline twice: a wave of household-name public companies cutting jobs and slashing dividends, and a quieter observation, usually buried further down the story, that the family-owned firm down the street just kept going. The pattern is common enough that researchers have spent two decades trying to explain it. The explanation
