Open access publishing is making the research literature freely available to the public. It will only be truly accessible if it is intelligible, but there are encouraging moves in that direction.
For another I (and others) hope that the fact of open access will create a demand-side pull on researchers strong enough to induce them to make their work not just accessible but intelligible. That is a non-trivial demand to meet. As a scientist I am well aware that the primary function of the research literature is to facilitate and formalise the exchange of information between experts in a particular field. For that reason the style is rather stiff — precision bracketed by caveat — and weighed down with jargon, features that are likely to repel readers lacking in determination. But scientists might offer a hand-hold by providing a lay summary, a simpler-stated account of their findings.
