Research astrophysicist. Particularly interested in astrobiology, paleobiology, extremophiles, origin of life studies and studies of ageing. Working toward a biochemistry degree when I have time.

Do trees age on a microscopic level? Thanks @Luke. Looks like a good read. |

Do trees age on a microscopic level? @Luke do you have a ref. for the second review you mention? The Cell website is down. |

How did the nucleobases in the Murchison meteorite form? But certainly the importance of dust should not be underestimated! |

How did the nucleobases in the Murchison meteorite form? I am not sure that I would say that we are left to speculation. The fact that these chemicals are racemic would suggest that they were formed abiotically. This being the case, we can probably get to understand the chemistry which should be pretty basic. |

How did the nucleobases in the Murchison meteorite form? @KonradRudolph The argument about reducing vs non reducing atmosphere goes on, but it probably was not as reducing as Urey Miller assumed. Not to take away from their very important contribution however. Regarding black smokers, yes they are favourite candidates for early life, but their chemical environments are not much like Urey Miller either! |

Does stress physically age our body? I didn't say there was a contradiction, but as you have just said it a clearly more complicated than saying stress=bad. |

How did the nucleobases in the Murchison meteorite form? See my response below. The problem with Urey-Miller is that they assumed a strongly reducing environment which probably was not the case on the early Earth thereby giving them very high yields of lovely organic stickies. |

Does stress physically age our body? Not sure that I am entirely convinced by this. Some studies have shown (looking for refs...) that stress can be an important stimulant of the immune system - i.e. hormesis. |

What is the relationship between migraines and histamine? This seems to suggest that some sort of antihistamine would be effective in treating this class of migraine. Is that right? |

How did the first self replicating organism come into existence? No, I just mean that how are we really ever going to know what the exact sequence of events was? I suppose it depends whether you are a contingency or convergence type! |
