"Together with the rolling of larger droplets, this ‘bubble dance’ also removes any contaminants from the lizard’s back. In other words, gecko skin is unwettable and self-cleaning. It is also inherently antibacterial. “The hairs seem to kill the bacteria not with chemistry or anything, but [they] seem to penetrate the bacteria,” Greg says. Although it is lethal to microbes, larger cells – such as human stem cells – are not harmed by this spiky surface."
"“There are a lot of pressures now, where you have to publish or perish, so to speak,” says Jolanta. “But Greg and I have a very firm philosophy that science is about discovery and just basic human curiosity. A lot of our projects just come about from really never growing up,” she says. “We’re always at that five-year-old stage, where we pick things up and we look at them.”
I agree. Always be five years old.

Always loved the humble gecko and their mastery of van der waals forces, this just adds to their wonder.
ReplyDeleteI'm particularly intrigued by the idea of a physical active defence against bacteria. Not just stopping them from entering the body, but actually killing them on contact without chemicals. Reminds me of Species 8472.
