TechNetters, I get a weekly email from the American Physical Society with 5 or 6 stories about recent research, of which I read 1 or 2. http://physics.aps.org/synopsis-for/10.1103/PhysRevApplied.1.044001 is the third one this week, Growing Whiskers. For details, we would have to go to the original paper, but the summary is intriguing.
