The National Academies' "Grand Challenges for Engineering" list, released yesterday, runs down the 14 most pressing issues we must face in the 21st century. Creating access to clean water ... restoring our cities ... engineering new medicines and new ways of providing care ... the list is vast and inspiring. Look on the Next Steps area to find out where we can go from here.

The committee that selected these 14 Grand Challenges includes TEDTalks speakers Jaime Lerner, Dean Kamen, Craig Venter, Larry Page and Ray Kurzweil.

Sing a song of cities: Jaime Lerner on TED.com

With maverick flair and a strategist's disdain for accepted wisdom, Jaime Lerner re-invented urban space in his native Curitiba, Brazil. He talks about how to revolutionize bus transit, awaken green consciousness in a populace accustomed to litter and blight, and change the way city planners and bureaucrats worldwide conceive what's possible within the tangled structure of the metropolitan landscape. (Recorded March 2007 in Monterey, California. Duration: 15:42.)
