Space flight alters bacterial gene expression and virulence and reveals a role for global regulator Hfq. Proc Natl Acad Sci USA. 2007 Sep 27; [Epub ahead of print] (PI: C.A. Nickerson) Note: STS-115 results. This significant paper received widespread media coverage; for a sample, search the name Cheryl Nickerson on Google News. The Washington Post article was on the top of page 3 of the Post.

J Appl Physiol. 2007 Sep 13; [Epub ahead of print] (PI: K.M. Baldwin) Note: Summary, from paper: "The results of the current study indicate that a resistance exercise protocol that combines isometric, concentric and eccentric modes of contraction with an accumulated volume of training greater than that reported in our previous study, results in a suppression of catabolic signaling (myostatin) and the maintenance of anabolic processes such that the muscle atrophy response to unloading can be effectively blunted."

J Appl Physiol. 2007 Sep 20; [Epub ahead of print] (PI: M.D. Delp) Note: From conclusion in paper: "This diminished vasoconstrictor response of white adipose tissue coupled with the increased percentage of body fat with old age (reference provided) provides a clinically relevant mechanism that may contribute to the orthostatic hypotension that is prevalent among the elderly."
