Articles on animal migration published in BioScience
...the complexity of migration is such that trying to predict
the consequences for species in general borders on the impossible. Yet only by obtaining a clearer picture of how migration really works will researchers be able to plan strategies for mitigating the effects of warming. BioSciences special section o...

clinical outcomes for patients based on their individual gene expression profiles. The authors closely scrutinized the statistical methods and reporting in 42 studies published in 2004. Half of these studies (21) contained at least one basic flaw. ...
