Radishes And Rockets - SpaceDaily  The easy-to-grow vegetable has been identified as a salad crop for space missions because it is small, grows rapidly, and provides essential nutrients. Since water floats in space, astronauts depend heavily upon moist wipes similar to those you might use to wash your hands when traveling. These wipes contain alcohol that evaporates into the spacecraft's air. But this airborne alcohol - in just a small percentage of the allowable safe limit for the crew - can kill the radish plants and affect even the soil they grow in. Grown in air with just 10 percent of the allowable alcohol limit, the radishes are undersized. With 25 percent of the limit, the plants die.    
Robots That Act Like Rats - SpaceDaily  Left:  This robot was designed with the same basic senses and motor skills as a rat pup. Photo by Sanjay Joshi & UC Davis. Seven to 10-day-old rat pups, blind and deaf, do not seem to do a whole lot. Videotaped in a rectangular arena in Schank's laboratory, they move about until they hit a wall, feel their way along the wall until their nose goes into a corner, then mostly stay put. Because their senses and responses are so limited, pups should be a good starting point for building robots that can do the same thing. Joshi's laboratory built foot-long robots with tapered snouts, about the same shape as a rat pup.   

Open Nanofluidic Systems - SpaceDaily  Left:  Atomic (or scanning) force microscopy images of liquid morphologies on silicon substrates with rectangular surface channels which have a width of about one micrometer. On the left, the liquid does not enter the channels but forms large lemon-shaped droplets overlying the channels (dark stripes). On the right, the liquid enters the channels and forms extended filaments separated by essentially empty channel segments (dark stripes). In the bottom row, several parallel surface channels can be seen in both images; in the top row, there is only one such channel with a single droplet (left) or filament (right). Close inspection of the upper right image reveals (i) that this filament is connected to thin wedges along the lower channel corners and (ii) that the contact line bounding the meniscus of the filament is pinned to the upper channel edges.
