Study Challenges Evolutionary Relationship Between Flagellum and Type III Secretory System

There are various types of flagella, but all function like a rotary engine made by humans. Even non-ID scientists marvel at the complexity of these machines. Read More ›

Closer Look at the T3SS Reveals Design

If one visualizes the recoil action of large guns on ships as they fire, that is perhaps what the EA (export apparatus) is doing for the T3SS. Read More ›

Darwin Devolves, Again: Study Finds Bacteria Eject Their Flagella to Avoid Starvation

This finding fits Michael Behe’s book Darwin Devolves perfectly. It’s easier to throw cargo overboard than to create it. Read More ›
