PLuTARC: Target-Locking Microscopy

In any typical data gathering process, objects are observed from a fixed viewpoint (think of a camera on a tripod). If the objects are moving, this limits the observation time, as the objects move out of the field of view. In a microscope, this is a particularly severe problem when studying moving objects like swimming cells, or freely-diffusing cluster of colloidal beads. What we've done with the PLuTARC (Peter Lu Target-Locking Acquisition in Real-time Confocal) system is to implement target-locking.

Colloidal phase transitions on the Int'l Space Station with GPGPU

Under normal conditions on earth, the separation between liquids and gases is usually a bit mundane: the level of water in a drinking glass simply falls as the liquid evaporates into a gas, since the liquid is denser. Two liquids of different densities, such as the oil and vinegar of salad dressing, are similarly unexciting; the oil just floats to the top after a period of time. However, when the effects of gravity are taken away, such as in the environment of the International Space Station (ISS), this separation creates far more interesting and complex patterns.
