  1. Re:not exactly news on Study: Martian Soil Has Signs of Life · · Score: 1

    Theoretically that's possible, but the problem is that proteins themselves don't do well in highly oxidative environments which is why you have to store proteins in reducing agents like DTT. So you'd need to have basically all proteins (with the exception those resistant to oxidation) in 'wet vacuoles' along with RNA and DNA. With a system like that, you'd need to have virtually most of the cell in vacuoles, so you then run into the problem of freezing again. However that doesn't mean that an entirely different biochemistry isn't possible, just that it couldn't be anything like the aqueous chemistry that is ubiquitously found in life on earth.

  2. Re:not exactly news on Study: Martian Soil Has Signs of Life · · Score: 1

    Generally when found in significant concentrations (ie not some transient intermediate in a reaction) it's limited to specialized vacuoles that keep it isolated from the rest of the cell as it's a fairly strong oxidizer and would damage things like nucleic acids (DNA/RNA) and proteins. While I'm hesitant to rule something like this out of hand, if they are suggesting that these organisms have high hydrogen peroxide concentrations, then that would require a completely different biochemistry unlike anything we currently know of.

    3) Noah did not really have two of every species on the ark (I guess somebody calculated that the ark would not have been able to hold all of them), rather he had two of each "type". For example a pair of wolves would stand in for their species as well as dogs, dingos and coyotes, etc. Interestingly, this creates another problem in which you'd need to have a bizarrely accelerated mutation rate to allow expansion of the 'kinds' into new related species in just 6000 years and then have that mutation rate slow down to the rates we see it today.

    I don't think it's necessarily that clear cut. It's a commercial event which generally weighs heavily against fair use arguments, which is why clips from movies and sporting events can't be shown without consent. Plus a dateline news segment is likely going to show significant more of the talk than a simple news blurb that fair use normally applies to.

    I agree with you that it's not wiretapping. My point is that presentations like that are protected by copyright. You can record a play if you get permission from whoever owns the copyrights, but the actors would need to sign their copyrights over (or sign them to the theater). I've had to give 2 public presentations at conferences that were taped by the organizers and both times I've had to sign copyright transfer agreements to them. Same thing applies to sporting events, you can't go to Vegas and videotape a boxing match without their consent.

    It's about copyright infringement not wiretapping. You don't lose your copyrights to a presentation just because you are in a one-party state.

    Also, most privacy laws go out the window in any sort of public venue. It's not a public event, the venue is held on private property and you have to register/pay to attend.

  12. Re:Why would an international conference be in the on US Blocks Entry For German Black Hat Presenter · · Score: 1

    A large component of the Blackhat conference is the training sessions. In fact the name of the conference itself is Blackhat "USA 2007 Briefings & Training". It was very likely to be prominently displayed on the actual contract he showed the Immigration officer, so I don't think it would be much of a leap for an American (or Canadian) immigration officer to inquire if he was doing any training which, depending on how he answered, could make that clause apply and make him non-except.

  13. Re:Why would an international conference be in the on US Blocks Entry For German Black Hat Presenter · · Score: 2, Interesting
    Sure about that? I just looked at the documentation you linked and this seems identical to the issue in the US (From R186(j)):

    Commercial speakers have a vested interest in the event at which they are speaking. Typically, they rent commercial space in a hotel, advertise, charge admission, deliver the event and then leave Canada. If they are doing this for no more than five days on one trip, they can enter under R186(j). This regulation covers situations where the speaker is speaking to multiple groups, as long as the duration of the speaking events is no more than five days, not counting travel time in the case of multiple engagements. Not included in R186(j) are commercial speakers who are hired by a Canadian entity to provide training services. In these cases, other entry options must be explored including HRSDC LMOs or the NAFTA Professional category which allows for professionals to provide training services under some circumstances. So if he went to Canada and said he was being paid by a Canadian company to provide training services, he would need a visa.
  14. Re:Not that surprising... on Adult Stem Cell Growth Treats Cornea Disorders · · Score: 1

    Wrong. Adult stem cells are essentially just easier to use for certain applications where the adult stem cells is easily differentiated into whatever tissue you are trying to grow. Which is why there have been a number of successful uses of adult stem cells, particularly in hematologic disorders because blood progenitor stem cells have been extensively studied, so we know how to make them do what we want. By definition, an embryonic stem cell can do anything that an adult stem cell can do (adult stem cells come from embryonic stem cells) and more. However we've only really began studying embryonic stem cells, so the problem has been figuring out the various signals that make a stem differentiate into what we want to make. Adult stem cells are just "easier" because they've already partially differentiated, so there are less steps. It's the fact that they've already partially differentiated that makes them somewhat limited (ie a blood progenitor stem cell can only become various types of blood cells, but can't become a spinal cord nerve).

  22. Re:The decline of ethics????? on Consumerist Catches Geek Squad Stealing Porn · · Score: 2, Insightful

    The smart thing to do, given that there aren't even basic ethics or civics classes being taught anymore in public school, is to assume that is is eminently possible that your files might be looked through. IMO, I think that whether this was the "smart" thing to do is the irrelevant part. Sure it's stupid to walk down the street with a wad of $20 bills in my hand, but that doesn't make it ok for someone to steal it. The job they were paid to do did in no way require them to be looking through those files and as such the owners had a reasonable expectation of privacy.

    This is through no real fault of the kids in question, other than that they are the ones who transgressed, but rather the society, mainly the parents, that brought them up. While I strongly agree that good parenting is a huge component, everyone knows that taking other peoples stuff is wrong and you have to take personal responsibility for your actions at some point.
