## Researchers Outline Obstacles and Solutions for Providing Water in the 21st Century

**The researchers found that the process is dominated by fluctuations of the membrane surface itself. **
**Such fundamental research is critical to understanding the processes that drive cell functions at a molecular level and could eventually lead to new **
**approaches to dealing with dangerous microbes.**
