One expects a hurricane to bring heavy rain, but the volume of water brought by Hurricane Harvey – which has so far produced about 50 inches of rain and nine trillion gallons of water – is hard to fathom. Colorado State’s Russ Schumacher, who studies extreme rain events, explains the meteorological reasons why this storm has been such a prodigious rain producer.
Amid disasters like the ones in Harvey’s wake, millions of Americans make donations intended to ease the burdens experienced by people whose lives are being upended. Choosing which groups to support and how to give is harder than it might appear, says David Campbell, who teaches nonprofit management at SUNY Binghamton.
And it’s time for a major rethink of your passwords. They’re the keys to your digital life, and over the past few years it’s become common to think that a secure password should Lo0k a l!ttl3 çra$y. A team of researchers at Carnegie Mellon has been examining whether that’s true, and new federal guidelines about passwords echo their findings.

As Hurricane Harvey shows, flooding can happen wherever large storms stall and dumps lots of rain. A new study finds that development is increasing in flood zones inland, where people may not think they are at risk.
