"... virtually unique in their ability to attain dry stickiness." geckos are talented little buggers, that's for certain. effective pitchmen, as well. but what about those toes? just how does a gecko manage to shimmy up the slippery side of your aquarium with the greatest of ease? well, according to researchers at lewis and clark university, it all comes down to hair....
And then I'll wait for that webshooting thingy in my wrist.

I'm putting off becoming a serious rock-climber until I can get some Van der Waals gloves. (explanation of VdW forces - 1, 2)

I always wondered, how do the people mistakenly call up Gecko when they want Geico? Do they look in the Yellow Pages? One would think most partisan, conformist, instant-messaging, Steve-is-so-cute-so-I'll-buy-a-Dell people would go to the website. I mean, it looks like every facet of that little green guy's life is interrupted by some jackass calling for auto insurance.
Well, at least he has those little hairs to help him pick up the phone.

Okay, wait. Can someone more learned than I explain the difference between the current story and those that were published over two years ago?
Are we just recycling news here in the dog days of summer or is there something new here? I don't see it.

"We confirmed it's geometry, not surface chemistry, that enables a gecko to support its entire body with a single toe.."
Heh. Cool. While back I had a math professor who was deeply into geometry and visual learning stuff - iirc, he'd spent something like 20 years in the field (interestingly, his BSc was in logic, at MIT..) He does a lot of research into protein folding and such, and he's fond of saying "Basically, everything boils down to geometry."

They eliminated water-based attraction mechanisms (like wet sand sticking together) from the list of possible explanations, leaving only the dry van der waal's force as the explanation.
Basically, there's no goo involved in making it sticky.

One interesting thing about this that the article did not touch on, is that the problem isn't making something using this technology stick, it's pulling it off the wall at will.
If you were to have gloves that allowed you to adhere yourself to something just like a gecko, you would have to have some way of lifting up your hand to climb. The way that geckos do it is by contorting their hand (actually rolling their fingers backwards on top of themselves) which dislodges them.
If we want to be able to climb walls like this, we will need to come up with some clever way of unsticking ourselves.

Could a glove equipped with similar tiny hairs help a person cling to a wall like Spider-Man, the cartoon and film character? "I watched 'Spider-Man' on an airplane and I couldn't help thinking we could do better than that someday," Autumn said.
I want that.
