  1. Re:A class act on Astronaut Neil Armstrong Has Died · · Score: 1

    Only Schmitt was a geologist/PhD. Scientist of the moon walkers. The rest less than 'not as much': The rest were test pilots who did have other related (aeronautical) degrees. At least of the Mercury original 7, Gemini 8 and Apollo 32 etc. The 4th group of astronauts were scientists. And only one walked on the moon.

  2. Re:A hero, but without the hype please on Astronaut Neil Armstrong Has Died · · Score: 3, Insightful

    I think that his great humility and quiet nature was what made him the perfect choice to do why he did. He was not the leader although he did command the moon landing mission. he was one who recognized and acknowledged the efforts of all who enabled him to do what he did.

  3. Re:Drug test the final standard? on Lance Armstrong and the Science of Drug Testing · · Score: 1
    Very good, thorough article, even if it is from 2009. There have been people who never tested positive who none the less were cheating and admitted guilt. Marion Jones anyone?

    Part of what makes this difficult is that doping/cheating in sports is not a criminal offense in the USA. Lying about it to investigators may be, but doing it is not.

    Very vague news release. Anyone could say the same things.

    The only interesting part is where this group has removed an astronaut-candidate (not?) due to 1: letting a student post pictures of her in lingerie and 2: assaulting/attacking/biting someone and being arrested.

  6. Re:After last night's coverage on NBC... on Why You Should Be More Interested In Mars Than the Olympics · · Score: 1

    I'm missing the CBC coverage as I am visiting the USA. The NBC coverage is poor. It does seem very jingoistic and narrow minded. I like how they have named the 'evening' coverage 'NBC Live' even though it is taped.

    I'm pretty sure I can follow both. And be interested in both.

  8. Re:The chicken and egg problem all over again on Cat Parasite May Increase Risk of Suicide In Humans · · Score: 5, Funny

    Do the crazy cat ladies have cats because they are crazy, or are they crazy because they have cats?

    The parasite also causes decreased sexual inhibition. Translation: It makes women sluttier. No corresponding effect was found in men. Of course, this effect isn't as widely documented for obvious political reasons...

    That is because in men there is no sexual inhibition to effect.

  9. U235 + software = U238?? on Iran Claims New Cyber Attack On Its Nuclear Plants, Blames US and Allies · · Score: 1

    The beauty of these software attacks is that the Iranians cannot trust most of the numbers the computers are showing. Not just on the control side of things but also the specialized equipment that assays, say, the purity of the uranium isotopes. So they would have to go back and redo the assay with equipment that they really can't be sure is accurate.

    Is there such thing as 'fair use' with a small enough snippet as there is with writing? ie: "It was a dark and stormy night..." then go on with a zombie story.

    I don't think that chord progressions are subject to copyright. Otherwise mashups would not work so well, or Axis of Awesome could not do this (4 Chords) : http://www.youtube.com/watch?v=QpB_40hYjXU

    I am sure for both amateur and professional astronomers that this would result in horrible seeing conditions as well. Please look at http://www.darksky.org/. Dark night time skies are hard enough to find due to light pollution even now. Better than global warming I guess!

  13. Re:The future will be printed, not forged. on An 8,000 Ton Giant Made the Jet Age Possible · · Score: 1

    The "ability is lost" when the last plant capable of doing it shuts down. The knowledge isn't lost (we hope), but for various reasons (typically it was being done cheaper overseas) the actual facilities will close. If we had to, we could rebuild/reopen the plants here, but it would take a few years and the investors would want some sort of guarantee that the same economic forces that caused the previous plants to close won't apply to the new plant.

    One item you can add to the economic decisions are the environmental decisions. It may be considered "too expensive" in environmental costs/damages to rebuild a plant or utilize a manufacturing process. So although the knowledge is there, it cannot be acted upon.

  14. Re:X-Ray Film stock versus Digital Imager on FDA Cracking Down On X-ray Exposure For Kids · · Score: 1
    Coming from the dental side (a dentist) with small exposure areas and low dosage to start: Compared to 'medical' imaging the dosage with a digital sensor is considerably less than that needed even with 'ultra-speed' film. On the order of 30-50% of the exposure time, not counting improper exposures that would need repeating. The acronym is ALARA: as low as reasonably achievable, but still must give a diagnostic result. I do perform a lot fewer radiographs on paediatric patients than in the past even given digital advantages.

    Also the difference in looking at a computer screen 21' diagonal compared to a 1.5" film held up to a light box is considerable!

  15. Re:That means we lefties on The Science of Handedness · · Score: 1
    " switch-pitchers must choose which way they will begin pitching before they start. Then, batters will select with which hand they will bat. The batter and the pitcher are each allowed one switch during the plate appearance, after the first pitch is thrown." From MLB rules.

    The only modern pitcher to pitch in the major league is Greg Harris with the Montreal Expos.

  16. Re:That means we lefties on The Science of Handedness · · Score: 1

    That Baseball was able to capitalize on left handed pitchers throwing to much more common right handed hitters is a rather late innovation in the annals of human endeavor.

    Your point still stands, but you have the baseball backwards. Opposite handedness favors the batter.

    In batting in baseball, left side batting is favoured because the batter is one or two steps closer to first base, as well as their momentum from the swing going that direction. We often coach/teach people to bat from the left because of this.

  17. Re:The gap is about 35 years on India Test Fires Long-Range, Nuke-Capable Missile · · Score: 1

    But I think when talking technology/science, part of the gap can be closed by knowing generally (if not specifically) how something can be done - or even knowing it can be done. And with science, most of it should be published and available (minus defense secrets). And speaking of secrets, let's not forget espionage. It can close the gap quickly! Witness the Soviet Union after WWII and the bomb and also Pakistan in the 80's.

    In wonder if it would be considered cruel...

    In short, they understand language, and they know how to speek it. They just act as if they don't, because if they reveal it, then humans are going to put them to labor immediately.

I can see popping rock into the air/orbit further away from the impact site so they are not melted completely. Like snapping a towel. They would still be sunject to

    I have difficulty with the millions of years in the vacuum of space being irradiated by gamma rays (that we use to sterilize things now). Bacteria will not survive hundreds to thousands, much less millions of years on Earth! How long does it take bacteria to die on your kitchen counter/door knob, etc? Usually minutes to hours. Only certain kinds of spore forming bacteria can survive dessication (drying out) even.

    May I suggest: http://www.ncbi.nlm.nih.gov/pubmed/18225667 "One of the most important aspects of the problem of life transfer in the cosmic space is the resistance of microorganisms to high-temperature heating during the launch and entry into the atmosphere. The high-temperature limits of the survival of microorganisms were studied under conditions modeling the laungh from the Mars and the landing on the Earth. Two strain of E. coli K12 exposed to short heating pulse were studied in order to tind out if they could resist high temperature while being in the desiccated state. The procedure was performed in vacuum. It was found that a fraction of bacteria survive heating pulses up to 250 degrees C in vacuum, while similar heating at normal atmospheric pressure leads to the total sterilization of samples."

  20. Re:Inflammation on Aspirin Helps Prevent Cancer, New Studies Show · · Score: 2
    Inflammation is an immunological reaction by the body to a perceived insult. The immune system protects the other cells from bacteria, viruses, etc but can be damaging to normal uninvolved areas. The insult can be physical (ie: radiation), chemical (ie: acid) or even the inflammatory cascade switched on due to a malfunction of the switching mechanism (autoimmune). Although inflammation is not the direct 'cause' of a disease (except perhaps in autoimmune disease) it is often the 'cause' of the tissue injury and body response that is noticed (ie: signs and symptoms).

    The body does have an inflammatory response to most cancers (uncontrolled and uncoordinated cell proliferation).

    They were using kerosene originally to keep it from freezing. I do not believe the ice temperature is as cold as the ambient air either. Snow is a decent insulator. Ice maybe not so much though. The permafrost in the Arctic does not extend down 13000 feet (although it is not pure water). There must be some radiant heat from the earth. Generally temperatures increase 3 degrees C for every 100 meters deep.

  25. "Spacesuit: Fashioning Apollo" and Playtex on Next-Gen Spacesuits · · Score: 1
    If anyone is interested in a good review of the difficulties and challenges of spacesuit design and why the Apollo suits were such then read this book. It is by Nicholas de de Monchaux, ISBN: 978-0262015202.

    It is a good history of the technology in 21 chapters (like the 21 layers of the Apollo suit). What most don't know is they were made by the Playtex corporation. The book is less technical than it could be but is a very good read.
