Have you actually read their "Solution"?
I hope his confidence is well placed (Cough). It would be less suspicious if they'd be more honest and say POTENTIAL solution found in their headline. But hey, Scientists are allowed to say theories as facts for some reason. As it stands, this "Solution" is just one of many, like on the paper I presented. Perhaps they know that the word "Solution" doesn't necessarily have to mean "Proven solution" and exploit this for the less critically minded. Calling this "Solved" as a title is very misleading for people who haven't actually read the article, it makes it out like they actually figured it out hands down, and people like you who haven't read it actually believe it. Now try reading it and tell me if they actually "solved it" or "think they have a potential solution that hasn't been tested".
Or if they really wanted to be honest, they'd say "Encouraging approach" discovered.
An "Encouraging approach to understanding" does not make a problem "solved". I wonder if the person who titled the article even read it. The disconnect is glaring. I wonder if this is the reason you didn't actually quote from your article.
But Scientists aren't well known for honesty, have a diet soda if you disagree.
