Pretty image huh? It's all natural and glowy, and you almost expect it of an Apple computer. It's the thing of calming screensavers. So what is the story behind this image?
Sperm. So the story is, there have been experiments where scientists have tagged mice sperm with UV and been seeing how they react. They bunch together for the challenge at hand, so to speak. And what's more, if the sperm find sperm of another male, the "brothers" will bunch together and literally crush the opposition.
Charming. Don't you love how images can give you so many thousands of words but hide what might be the true story?
