I just stumbled upon a nice new initiative called frontiers for young minds. There is by now a relatively large collection of frontier journals that cover most fields of science. All their journals are open access which means that they are available to everyone for free when published and the authors maintain copyright. Their peer review system is also different in that the identity of the reviewers is revealed when a paper has been published. This probably reduces ad hominim attacks and instead encourages a respectful tone, which is unfortunately not something that can be taken for granted.
The frontiers for young minds is a new journal where children, together with scientists, review the articles. This has the benefit that it forces scientists to write in such a way that children can understand it. I think that having such a journal could really help children and also adults who find it hard to read traditional science journal, get into science in the first place. I am not arguing that traditional journals only contain unessecary jargon, but rather that this type of journal is probably needed. I will keep checking the page and probably read some of the articles as well.
As an example, see this article: Do you feel lonely? You are not alone: lessons from social neuroscience.
