Every year, the site Edge.org [5] a question to about 200 people at the research frontiers. Among those surveyed are geneticists, physicists, philosophers, people who work with artificial intelligence, plus the odd wild card, as Kai Krause (maybe someone will remember the wayward landscape modeling program Bryce; it was his work). The questions of the type "What have you changed your opinion about?" Or "What a scientific idea, it is time to retire?" The aim is to provoke thoughtful responses. This year was the question "What is the most interesting scientific news?" [6]

The answers are not always intellectually dope, but together they provide a snapshot of what is going on in the various research fields. What will we learn about in the next few years? Bacteria. The realization that man is dependent on the interaction with bacteria and parasites are breaking through.The bacteria on us and in us control gene activity in our bodies, writes bioantropologen Nina Jablonski. A poorer bacterial flora can lead to obesity, allergies, possibly autism. Perhaps we will soon see ads for bacterial smoothies to everything from obesity to depression.
