Description:

We show three recent experiments where we search for general principles in long-standing biological problems.  First, we ask how mosquitoes target hosts for blood-feeding.  We use 3D infrared cameras to track mosquito's flight.  We use Bayesian inference to determine the mosquito's behavioral forces based on the direction, speed, and distance from the host.  We then proceed into the mammal ear, where we find earwax has properties of both a fluid and a solid.  These properties prevent the crawling and grooming of insects.  Lastly, we discuss the mystery of bird-bathing, which may be involved in helping keep feathers fastened together.
