Double bubbles hold scientific promise


Doublebubble_1 Scientists have discovered how to squeeze bubbles inside bubbles, which may offer a way to smuggle all sorts of substances — from expensive perfumes to cancer drugs — into places they couldn’t survive without protection. The new method, developed by David Weitz of Harvard University and his colleagues, produces droplets in carefully controlled sizes, with multiple fluids nestling inside each other. Some of the most ambitious hopes for these multilayered droplets are in medicine, where it would be essential to control the amount of drug being delivered.

The findings appear in Friday’s issue of the journal Science, published by AAAS, the nonprofit science society.
