Scientists Marvel at Enzyme Efficiency
November 11, 2008
Many chemical reactions occur from simple collisions.  One atom may have spare electrons, another may need them.  Attracted by each other’s valences, the atoms collide and bonds form.  Not so with biological enzymes: these molecular machines owe their efficiency to their three-dimensional shapes.  Made up of hundreds of amino acids, enzymes have “active sites” where […]

Evolution in Person
November 10, 2008
For a blind watchmaker, Evolution is quite the seer.  Science articles often personify Evolution into a wizard and worker of miracles.  This is odd, considering that evolution is supposed to be an aimless, purposeless process of chance and necessity with no goals in mind. Evolution, the Learner:  Evolution learns from past environments, we are told […]

Darwin’s Prognosticators
November 4, 2008
Scientists at Rockefeller University think they can one-up Darwin.  According to Science Daily, they think they can predict evolution’s next best move.  Evolution is supposed to be aimless, so it is not clear how they think they can predict chance or decide what is best.  The dubious nature of their quest, however, is only exceeded […]

A clock with cogs, gears and ratchets that keeps accurate time – what more could William Paley wish for?  The 18th century natural theologian used the illustration of stumbling upon a watch in a heath as an example of reasoning from design to a Designer – as from watch to watchmaker.  Skeptics like David Hume […]

How Cells Thread a Needle
October 17, 2008
Your challenge today is to invent a machine that can push a wet noodle through a straw.  It can’t pull it.  First it has to grab the end, then push it through without breaking it.  Oh, and there’s a catch; the straw has a plug at the far end and a constriction inside.  Give up?  […]
