    From Discussion in paper: “In this study, we developed a model-based lighting regimen that was effective for entraining individuals at a normal phase angle to the 24.65-h Martian sol and to a 23.5-h rest-activity cycle. Second, we showed for the first time plasticity of the human circadian timing system that regulates period, with prior entrainment to non-24-h rest-activity and light-dark cycles resulting in long-term changes in the intrinsic human circadian period (after-effects of entrainment).” This paper can be obtained online without charge.

    From Author Summary in paper: “These results contradict the current dogma that the molecular response to randomly generated DNA damages is independent of their nuclear locations. Instead, this suggests the existence of repair centers in the nucleus. Overall, our approach shows that nuclear architecture plays a role in the DNA damage response, reminding us that the nucleus is not simply a soup of DNA and proteins.” This paper can be obtained online without charge.

    PLoS ONE. 2007 Aug 1;2(8):e687.
    (PI: P.L. McNeil)
    Paul McNeil is extending his NASA-funded research on repair of plasma membrane disruptions to other areas, such as a possible explanation of lectin toxicity (inhibitory effect of lectins on exocytosis involved in plasma membrane repair of gut epithelial cells), and, in a paper cited in the 8/10/07 list, about disruption of cell plasma membranes in the oral cavity due to toothbrush brushing. The paper cited above in PLoS ONE can be obtained online without charge.
