Surface tension and biology

This blog has tended to focus on methodological issues in science and medicine, but occasionally I do want to lavish praise for substantive work.  Here I'd like to call readers' attention to the delightful article in Science a couple weeks ago by Elizabeth Pennisi, "Water's Tough Skin."  It is a feature article describing a number of ways that surface tension is important in biology, including for plants, animals, and microbes.  A number of scientists, engineers, and mathematicians are interviewed about their work.  This is the kind of article that reminds us of why we became interested in science, engineering, and medicine in the first place.  I won't review the content here, but I commend it to readers to enjoy for themselves.
