    When we moved to Xenfora some of the signature options didn't come over. In the old software signatures were limited by a character limit, on Xenfora there are more options and there is a character number and number of lines limit. I've set maximum number of lines to 4 and unlimited characters.

    Merged Strict biological definitions of male/female

    Resolved: Hilton, Wright, & Heying are essentially correct about what makes a mammal either female or male.

    The deep biosphere

    The past few years scientists have been finding evidence of a huge subterranean biosphere. Reminds me of the new nematode found in that South African mine a couple years back. If we find no life on Mars we should consider digging. :)

    Unintelligent design

    A comment in the Intelligent Design thread has started me thinking. It seems to me that there are many instances where the design of the human body is obviously - not to put too fine a point on it - downright wrong. There are of course different trade-offs in any design, so it's not really a...

    Where does the weight actually go?

    This may be a stupid question, but I have asked it of other people and not gotten a real answer. Where does the weight you lose actually go? Do you burn it as fuel? Excrete it? I understand that you can lose weight and fat but not the mechanism.

    Bioprocessing questions

    For my Technical Writing class, I had to contact a local organization, preferably one related to my field, and interview them, asking them some major problems they have. I then recommend a solution by the end of the semester. I just recently switched to Mechanical Engineering as my major, and I...

    Aristotle's Lagoon

    Just watched this - http://www.bbc.co.uk/iplayer/episode/b00q0hh2/Aristotles_Lagoon/ - wonderful! Hide your IP address (PRISM permitting ;)) for non UK viewers, but a truly wonderful programme.

    Conservative/Lefty correlates to "appetitive"/"aversive"?

    http://www.guardian.co.uk/science/blog/2012/jan/31/socialists-conservatives-born-not-made Seems a little too neat to me. Are the "appetitive"/"aversive" systems actually real, or just a simple way of categorising lots of different responses to stimuli? I would suspect the latter. Anyone...

    Erik Andrulis paper "Theory of the Origin, Evolution, and Nature of Life"

    I've just been perusing this document, which seems to have been getting some attention on the web, after I was sent a link to it. [2MB PDF] Here's the abstract: It continues in this vein for 105 pages, includes a lexicon of dozens of new terms coined for this theory. Plus some nice gyroscopic...

    All mammals have roughly the same number of heartbeats in a lifetime?

    This was a Trivial Pursuit question. According to this reputable source, all mammals have roughly the same number of heartbeats over the course of a lifetime, except humans which have more thanks to medical care. Anything in it? A cursory google would indicate that this is certainly disputed.

    Freezing Eggs/embryos

    So children can be born from frozen embryos. But can little chickens hatch from frozen fertilised chicken eggs? Or are they too big? I would try and look it up but my brain is scrambled.

    Death by Belief

    I found this article fascinating, about a very superstitious group of people who had a tendency to die mysteriously in the night of no obvious cause. Some interesting ideas, and I think I'd like to get the book: snip

    Biology professor at Seventh Day Adventist college asked to resign over drinking

    Gary Bradley, an adjunct professor at the Seventh Day Adventist operated La Sierra University, has been on the radar of the adminstration because he doesn't accept young Earth creationism and this provoked problems with the church and school. Now, Bradley has been asked to resign for consuming...

    "Craig Venter Kills Sacred Cow of Evolution"

    This is what IDist people I know are crowing. Dawkins proved wrong! Tree of life is fiction! Based on the following: http://www.evolutionnews.org/2011/03/venter_vs_dawkins_on_the_tree_044681.html Of course the source's bias is clear, but is there anything to the claims within the article...

    Symbiosis vs. Parasitism (definitions)

    A long time ago (in a galaxy far far away), I remember learning the definition of symbiosis involved 2 species interacting with each other in a mutually beneficial way. Parasitism was defined as something all together different (one species benefits from the interaction, the other is harmed.)...

    Human Cheese

    So, do you reckon you could make cheese out of human breast milk? How much milk would you need to make a wheel of it? Would it taste Gouda? Or feta-id? Would there be a market for it online? In Japan perhaps? Would you eat some? These are the questions I have been pondering this very...

    Cool microscopic stuff to see at 150x?

    So, I was given a wee USB microscope for my berfday. Hurray! Highest mag is 150x though so I don't think I'll be able to see my own sperm. Shame - I've always wondered how they are doing. So, anyone have any suggestions about what is cool to look at between 10 and 150x? (I would go through...

    Biology of free will

    Split from the thread - is free will an illusion, yet necessary for ethics. I would like a discussion, evidence for/against, suggested reading etc on whether free will is physically possible. Is the brain capable of producing a choice that isn't predetermined? To give some context - I'm not...

    OCD possibly linked to immunity

    I found this interesting. Particularly from an evolutionary point of view - it strikes me that some OCD symptoms (obsessive cleanliness, revulsion at certain foods etc) could impart a survival advantage for someone with a faulty immune system. I'm sure I'm being rather simplistic though.

    ID is an ESSENTIAL part of science education.

    Although I was mildly interested in evolution before, I never really had the motivation to read about it in any depth at all. But thanks to the loudness and high media profile of ID proponents, with their smug little crowing faces and puffed up chests harping on about the need for more...
