I don't understand your comment - this is a news article. They tend to lead with the most important information, and explain that information as the article goes on. When a news article is about a scientific article, it will tend to start with the conclusion.

But I also don't understand your comment when compared to actual scientific articles. The high-level conclusions tend to be in the abstract and the introduction. Scientific papers aren't structured as mysteries, they try to front-load the important lessons up front.

Don't confuse articles about science, or papers by scientists explaining their findings, as the scientific process itself.
