Some like it hot ... or variable

by Celad Evra in SiGMA Cube


I have the impression that someone on researchblogging.org has already used a similar title to describe the link between rising temperature and vectors of contagious diseases. But [this article](http://dx.doi.org/10.1073/pnas.0903423106) has point...... Read more »
