Scientists have created a material that can be continuously tweaked between hydrophobic and hydrophilic states

Last year, a group of Harvard University scientists led by Dr. Joanna Aizenberg announced the development of a highly-hydrophobic (water-repellant) material known as SLIPS, or Slippery Liquid Porous Surfaces. The material is remarkable, in that it repels virtually any liquid. Now, Aizenberg and colleagues have created a new material inspired by human tears, the repellency of which can be fine-tuned for different applications.
