Homing In

Homing in on helminths.

I am honored to give this lecture dedicated to the memory of Dr. Fred Soper, whose pioneering efforts against the insect vectors of malaria and yellow fever are legendary. Soper and his col leagues also played key roles in restoring the con cept of eradication to respectability after the col lapse of earlier campaigns to eradicate hookworm and yellow fever. When Soper was himself in vited to gi...

Homing therapy

The BDNF-induced increase (left) in synapses (red) on a neuron (green) is lost if í µí»ƒ-catenin and cadherin are locked together (right). S tem cells become much more effi cient at muscle repair if they fi rst get a boost of cytokines and migratory adhesion molecules, report Galvez et al. (page 231). The improved repair stems from better homing abilities. Skeletal muscle can be repaired by a c...

Large Scale Homing in Honeybees

Honeybee foragers frequently fly several kilometres to and from vital resources, and communicate those locations to their nest mates by a symbolic dance language. Research has shown that they achieve this feat by memorizing landmarks and the skyline panorama, using the sun and polarized skylight as compasses and by integrating their outbound flight paths. In order to investigate the capacity of...

Visual Homing in Analog Hardware

Insects of several species rely on visual landmarks for returning to important locations in their environment. The "average landmark vector model" is a parsimonious model which reproduces some aspects of the visual homing behavior of bees and ants. To gain insights in the structure and complexity of the neural apparatus that might underly the navigational capabilities of these animals, the aver...
