Gecko Foot Design—Could it Lead to a Real ‘Spider-man’?

Gecko foot

A gecko can stick to almost any surface, so it can even run upside down on a ceiling of polished glass. This is due to the way tiny chemical forces are exploited by tiny hairs called setae, about 1/10 of a millimetre long and packed 5,000 per square millimetre (three million per square inch). The end of each seta has about 400–1,000 branches ending in a spatula-like structure about 0.2–0.5 microns—less than 1/50,000 of an inch—long (a micron is 1/1,000 of a millimetre). This is an amazingly fine structure that the researchers said was ‘beyond the limits of human technology’…

The Mystery of Dark Matter

It appears that there is a lot of mass that’s missing. In fact, this used to be called the missing mass problem. So what’s going on here? One possible explanation is that there is a lot of matter—a lot of physical stuff—arranged in a “halo” (a spherical shape surrounding galaxies). This has become known as dark matter. It’s physical stuff, thus the word “matter”—but we don’t see it, thus the word “dark.” …
