This is a three-sentence paragraph of 50 to 80 words written for interested non-experts, such as journalists, teachers, government workers, etc. The text should be free from scientific jargon, and written at the level of an article in a science magazine. Your first sentence should engage the reader, convincing them that this is an important area. The second sentence should introduce the problem addressed in the paper, and state your main discovery. The final sentence should describe how the results fit into the bigger picture (i.e. implications or impact of the discovery).
