Friday Links Round Up: Safe Water. Pizza Boxes. Nukes.

Safe Water. Pizza Boxes. Nukes. Here's a little round up of links from around the Web you may have missed this week.

• A simple solution to drinking water issues in developing countries.

• Some Jews, Muslims, and Christians abandon Yahoo and Google -- Andrew Sullivan calls it epistemic closure.

• Everything could use a smarter redesign -- even pizza boxes.

• Everyone must read Allison Johnson's rousing call to hope for the DREAM Act. Inspiring, right? Take action.

• Tell your senators, No More Nukes.

Have a happy weekend.
