I believe the most fascinating and the most meaningful news / blog and forum posts are that about scientific discoveries, no matter if they are big or not. Here is a few pieces of news I find pretty interesting:
1.Not So Sweet Tomatoes.
Using genetics scientists discovered why natural tomatoes from your arm are always sweeter than those you buy in a supermarket. They found so called genetic switch responsible for the level of sugar in tomatoes. Tomatoes bred for better transportation and firmness have this switch turned off. Now that the reason of that is known, scientists may create tomatoes that can both: remain fresh for a long period of time and be sweet at the same time.
