If this is a political question, it is in desagree with the rule for co-authors. There is a joke: "Some doctors have more than one article published or abstract in congress for days worked in medicine".
While not commending on the political or ethical aspects of this question as it has already been dealt with earlier, I wish to add an anecdotal fact in this regard.
Telomerase research was done by Blackburn at that part of the time when women did not even have a chance to get due credit in the research world or even an equal standing... She received her Nobel prize in recent years for her contributions.
But one of the most significant respectful detail she has revealed is that her research center chief always motivated the researchers to publish their findings with their own names as first author and did NOT include his name as an author in any of the work that he did not participate in. Because of this reason, there were many researchers who had published research findings as a 'single author' ... and he encouraged and supported this practice.
I suppose it was at Yale ... and the person due to be given credit is Joe Gall. Often he permitted his graduate students to publish as first author and also permitted single author publications for research he did not participate / contribute significantly in - a practice not common at that time leave alone for women ...
I believe this is a lesson that each one in the top ranks must learn and practice ... A lesson not just in female liberalization but also in concepts of ethical authorship.
