  1. Re:I do not understand why this is a story on Somebody Stole 7 Milliseconds From the Federal Reserve · · Score: 1

    You can't transmit information with quantum entanglement.

    It's like this - you have one very long coin which stretches between one place and another.
    At some point you toss it, and it lands either heads up or down. At the other location you try to toss it, but it's already landed, so you see the result.

    You don't know at which point in time the other end has been tossed, just that the two results are the same in the end, so it can't be used for communication.

    That's interesting.

    Now how about some research on actually persuading your child to have a nap, rather than a protracted battle of wills that gets everyone on edge.

    Naps are great when they happen, but all parties must be willing

    Why is the shin - the area of the body the most likely to get bashed into things - not protected by a fat pad? And why does it have such a poor blood supply?
    Why do hips - which bear the weight of the whole body - have a 90 degree bend in them?
    What's with the appendix?
    Why have testis outside the body, where they can be bashed easily
    Why do the ovaries not have a complete covering? (deadly ectopic pregnancies)
    Why is the appendix there at all?

    That's just a few working bottom up. I could go on.

  5. Re:FRAUD ALERT! JAMA again. on Tooth Cavities May Protect Against Cancer · · Score: 1

    JAMA seems to be an aggressive organization that sometimes promotes financial success for doctors against the interests of the public.

    The JAMA is the journal of the AMA, the doctor's union.

    It exists to promote doctor's interests. If it wasn't doing so it would be doing the wrong thing.

  6. Re:The bacterial excretions on Tooth Cavities May Protect Against Cancer · · Score: 2

    More to the point - head and neck cancer is very rare. Heart disease kills one in three.

    So reduce a very rare risk in order to increase a very common risk, plus suffer tooth decay as well? Seems like a pretty poor trade to me.

  7. Vaporize or ionize? on It Takes 2.99 Gigajoules To Vaporize a Human Body · · Score: 5, Informative

    Hang on a moment... TFA isn't talking about vaporizing - turning water to steam. It's talking about ionizing, which is clearly going to require a much bigger quantity of energy.

    For actual vaporization, making a very rough calculation - 60kg person, 2,270 kJ/kg latent heat of vaporization of water = 136 MJ,
    Sure there's specific heat to add in there too, but the vaporization of water is the dominant term, so it's at least out by an order of magnitude.

    Lesson learned - don't try and be 'all sciency' and use the wrong jargon!

  8. Re:Even if it does... on Scientists Silence Extra Chromosome In Down Syndrome Cells · · Score: 4, Informative

    By the time you've had amniocentesis to diagnose the disorder, the damage is already done.

    Development has largely happened by the 12-14 weeks at which point amniocentesis is viable, from there on it's really just growing with a few bits of finishing off.

    Unfortunately the only 'cure' for downs is to terminate the pregnancy when it's detected. In fact a considerable percentage of affected pregnancies end in miscarriage anyhow.

    I used to work in Geophysics programming geology models. It's really fascinating work, very enjoyable. Lots of maths of course.

    There is also good money in it, if you work for a mining company. I don't know if that satisfies your social conscience issues.

    In the end I got out of programming, partially due to the reasons you stated. I'm now a doctor.

  12. So what? on New Drugs Trail Many Old Ones In Effectiveness Against Disease · · Score: 5, Insightful

    So what?

    Sure the old drugs are great, but there's plenty of new ones that are great too.

    Take statins for example - relatively new class of medication that have dramatically changed the treatment of high cholesterol - which leads to the number one killer of heart disease. Another example - artemisinin - great treatment for malaria, relatively recent invention.

    Not to mention the survivorship bias http://youarenotsosmart.com/2013/05/23/survivorship-bias/ - there's heaps of old drugs that just aren't used anymore because frankly they were no good and had a ton of side effects. You don't hear about those ones much simply because they aren't used. This gives the perception that 'the old drugs are better' when in truth they were just as bad or worse, and only the good ones have stood the test of time.

    But even if it were true - should we then give up drug discovery? Give up the chance to find the next great drug just because the low hanging fruit are already taken? What exactly is the solution to this?

  13. This would be great if... on Montreal Union Wants a Camera On Every Policeman's Uniform · · Score: 1

    it was 'always on' of course.

    There will be still some ability for the officer to turn it off however - think about what happens when they go to the bathroom for example. I'm not sure they'd be too keen on having that filmed.

    For best use case the camera would send the video footage over the phone network in real-time, along with a GPS and time-stamp information in every frame.

    That there almost guarantees a clean police force on the beat.

    Shouldn't be too hard to measure. The wavelength is long, and tide gauges are built so short wavelength stuff (sea waves) doesn't change them. They are basically long tube with the bottom down fairly deep. The wavelength of tsunami are in the km.

    The thing I found odd was all the other measurements in this article are in metric, then a sudden switch to imperial units. That's odd.

    1. The major forms of transmission for hepatitis b are anal sex and iv drug use.

    Incorrect, the most common form of transmission worldwide is vertical transmission, from mother to child at birth. Vaccines prevent this. Furthermore the vertical transmission of hep-b causes the worst damage, with the highest likleyhood of ending up in cirrhosis, and early death from liver cancer. So while the incidence near birth is low in the west, the consequences are higher making vaccination more worthwhile.
    Secondly, there will reach a point where your son could experiment with IV drugs or even homosexual encounters, don't you want him to be protected in that instance?

    If you are alergic to bakers yeast then you will likely be alergic to the hepatitis b vaccine.

    You cannot have an allergy at birth to anything. It takes at least one contact with the allergen to build up an immune response.

    Why should I stress my son's immune system out

    Your son's immune system is 'stressed out' by the new contact with the world outside the womb. Adding any number of vaccines is a tiny drop in the ocean compared to all those new antigens.

  25. Re:8 years ago... on Ask Slashdot: Best Way To Take Notes In the Modern Classroom? · · Score: 1

    I also went back to (med) school six years ago. My experience is pretty similar to the above, although I do have some more to add:

    At first in med school I used to take my laptop, and annotate the (provided) powerpoint slides in onenote. Over time this dropped off, I still attended every lecture, but by the end of the first two years I wasn't taking any notes at all. I found that note taking wasn't really required for me to learn things, so I switched to just reading the textbook prior to lectures, and then attending the lectures and letting it soak in.

    I did find onenote quite a good program when I was taking notes. My laptop was an early tablet with pen input, which I thought would be useful when I got it but in the end I just switched back to typing because I can do that without looking at my hands or the screen.
