Abstract: A toy-vehicle launcher is disclosed that includes a track member having a loop track section, a launching mechanism, and a base pivotably coupled to and laterally extending from a bottom portion of the loop track section. The launching mechanism includes a vehicle receptacle coupled to a first end of the track member, a trigger coupled to the vehicle receptacle, and a shuttle biased to move in a first direction along the vehicle receptacle from a loading position to a launching position. The trigger actuates to release the shuttle from the loading position. In addition, the track member and launching mechanism can be pivoted about the base by application of a lateral force on the trigger.

Abstract: Disclosed herein are methods and apparatuses for sequencing a nucleic acid. These methods permit a very large number of independent sequencing reactions to be arrayed in parallel, permitting simultaneous sequencing of a very large number (>10,000) of different oligonucleotides.
