cunniff writes "Wired Magazine points us to recent research that demonstrates an algorithm derived from the actual biological implementation of fly vision (PLoS paper here). Quoting the paper: 'Here we present a model with multiple levels of non-linear dynamic adaptive components based directly on the known or suspected responses of neurons within the visual motion pathway of the fly brain. By testing the model under realistic high-dynamic range conditions we show that the addition of these elements makes the motion detection model robust across a large variety of images, velocities and accelerations.' The researchers claim that 'The implementation of this new algorithm could provide a very useful and robust velocity estimator for artificial navigation systems.' Additionally, the paper describes the algorithm as extremely simple, capable of being implemented on very small and power-efficient processors. Best of all, the entire paper is public and hosted via a service that allows authenticated users to give feedback."

Aspirin's mechanism of action was unknown for a long time, but now we know it's due to suppression of prostaglandin synthesis by irreversible inhibition [wikipedia.org] of cyclooxygenase enzymes.

No. Addition is the subject of the verb makes. Subject-verb agreement says the original post is correct. Get your grammer rules right first if you're going to criticize.
