By this point, we do not need to tell you how popular zebrafish are. We also probably do not need to point out the great technological advances that are being made in research because of the use of optogenetics.
Ever heard of quantum dots? These dots are nanoparticles made of a semiconductor material, which have unique optical properties, making them of great interest for fields such as biological imaging, medical diagnostics.
Video tracking is used to track a widevariety of animal species in even more different test arenas. From insects of 1 mm on leaf discs, to monkeys in a cage, or zebra fish in an aquarium.
Having a choice for a mating partner is extremely important for females, so they can be critical in choosing which male to mate with.
