How to Teach a Fish to Swim
We have developed a virtual fish tank in which computer users are represented by animated fish. The actions and interactions of the fish in the tank are meant to reflect the actions of users in the real world. Our first attempt at creating a programming environment that allowed people to customize their own fish did not work very well because users did not want to explicitly write programs to c...
متن کاملThe Secretion of Oxygen into the Swim-bladder of Fish
Fish were maintained in sea water equilibrated with a gas mixture containing a non-equilibrium mixture of the three molecular species of oxygen, O(18)-O(18) (mass 36), O(18)-O(16) (mass 34), and O(16)-O(16) (mass 32). Analyses in the mass spectrometer, of the gases secreted into the swim-bladder showed that no change in the relative abundance of these three molecular species had occurred during...
متن کاملLearning to swim, again: Axon regeneration in fish.
Damage to the central nervous system (CNS) of fish can often be repaired to restore function, but in mammals recovery from CNS injuries usually fails due to a lack of axon regeneration. The relatively growth-permissive environment of the fish CNS may reflect both the absence of axon inhibitors found in the mammalian CNS and the presence of pro-regenerative environmental factors. Despite their d...
متن کاملFish sex: why so diverse?
Introduction In most animal species, males and females behave differently, especially when it comes to sex and related social behaviors. These behaviors evolved to ensure successful reproduction and typically include some genetically preprogrammed displays. There are 25,000 known species of fishes, by far the largest group of vertebrates, and they express a remarkable variety of adaptive respon...
