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’…

A new study by NASA scientists has just been published where researchers did nothing more than convert a pre-cursor chemical into a single type of amino acid. Despite the simplicity of this experiment and the lack of anything helpful to evolution being found, the popular media exclaimed that the scientists were able to “recreate the ‘origins of life’ and the results are shocking.” In reality, the only thing shocking about this news story is the blatant absurdity of the claim…
