The latest issue of Science is out and here are a few items that may be of interest:
In the ScienceScope section, a brief news item reports that scientists are of two minds about open-access journals. According to a poll done by researchers from Munich University in Germany and the University of Arkansas, Little Rock, researchers like the idea of open-access journals as readers but believe that, as authors, publishing in such a journal may hurt their chances for tenure.
MicroRNAs get a bit of glory in this issue with a couple of papers highlighting their function. Christine Mayr et al. at MIT report that the loss of miRNA repression of an oncogene leads to tumorigenesis. Also, lead author Robinson Triboulet, from the Institut de Génétique Humaine in Montpellier, France, shows that, when replicating, HIV-1 suppresses an miRNA pathway that is thought to be involved in silencing DNA and RNA viruses.
