  1. Re:Why oh Why on Final Analysis Suggests Tevatron Saw Hint of the Higgs Boson · · Score: 1

    Going back further, Fermilab had a chance to be expanded to a state-of-the-art facility that could have made the LHC moot. But under the first Bush, rather than building on the existing infrastructure at Fermilab, the Superconducting Super Collider began to be built from scratch in Texas (surprise, surprise). Then the SSC went over budget (surprise again) and was cancelled after spending $billions. That gave the LHC its' chance to outshine the competition. More budget cuts now mean the government won't support ongoing research at the Tevatron, especially since it is not state-of-the-art like the LHC.

    They're delivered by guys earning minimum wage who don't receive security vetting.

    Actually, in order to drive a delivery truck into the airport, or get anywhere on the "airside" of the airport without a plane ticket, you need an airport ID badge, for which you do get fingerprinted and background checked. To get a badge, I even had to sign a statement that I hadn't been convicted of certain felonies, including murder, arson, and highjacking, in the last 10 years.

    If 50 cell divisions created errors in 1/3 of all genes, then life would be doomed before 50 generations pass, since the germs cells also must replicate, at least once per generation. Also, just to clarify, telomerase is not a gene, it is a repeating stretch of DNA that ends the chromsome, like the plastic tip of shoelaces that keeps them from fraying. I have no clue how telomeres could possibly "divvy-up the workload" as the parent says.

  6. Re:Upgraded toilets on Gates Foundation Makes Progress On Reinvented Toilets · · Score: 2

    Have to comment, since I design plumbing for a living:
    It's true that "water saving" 3.5 gal per flush water closets are no longer sold, but the current standard is 1.6 gallons per flush (not 1 gallon as stated by the parent post). There are some ultra-low flow units being sold that are 1.28 gallons per flush, but almost none less than that.
    A few years after 1.6 gpf was mandated in most codes, testing was done which found that many 3.5 gallon-per-flush water closets performed worse than most of the new 1.6 gpf fixtures, and on average there was no real reduction in performance going with the lower flow fixtures. (Of course, if similar research and development had been put into the 3.5 gpf fixtures, they could have been improved)
    While I do double flush, I have a 3.5 gpf toilet at my house that I regularly block up, and I'm pretty sure that I could stop up one of the old 5 gallons per flush toilets, too.

  7. Re:Eventually, but probably not too soon on Carbohydrate-Based Synthesis To Replace Petroleum Derived Hydrocarbons? · · Score: 1

    First, to clarify, peak oil is not when oil production peaks, it is when production outpaces the discovery of new reserves. There is reasonable evidence that this has already occurred, though we probably won't be able to tell for sure until well after the peak.
    Increased prices have indeed increased the proven reserves by making it economical to spend lots of money developing hard-to-get pockets of oil. This can't really reduce oil prices, though, since the high prices are required to make that production feasible
    Frakking is not really one of the things that will bring more oil, it is mainly for extraction of natural gas.
    However, peak oil is one thing, but natural gas and coal are far from being used up. If oil prices rise enough, we will be able to use natural gas and coal as feedstocks instead.

  11. Re:I'm not sure I see the need on Should Microsoft Put Office On the iPad? · · Score: 1

    Many (most?) people don't actually create content using Office. They just read/view the results, perhaps with minor editing.

    To the contrary, in the offices I've worked, even discounting e-mail, around 90% of employees create content with MS Office (or occasionally Wordperfect/Open Office) The only ones not regularly using an office suite to create content were the CAD operators and the president of the company. Of course, if you're working in a different type of office, like a call center, YMMV.

  12. Re:Almost right. on In Hot Water: The Effects of Even Modern Nuke Plants On Water · · Score: 1

    Some modern plants use super-critical "steam", and the water never really boils. And from room temperature to just below boiling at atmospheric pressures, liquid water expands around 4%, not under 1%.

  13. Re:Interesting definition of "modern" on In Hot Water: The Effects of Even Modern Nuke Plants On Water · · Score: 1

    PWR and BWR reactors are the main operating principle of the reactor - in both cases, water cooling.

    No, the PWR and BWR reactors use water/steam as the working fluid. The fact that they also use a secondary cooling water loop as a heat sink for their thermodynamic cycle is a separate issue. I suspect most "modern" non-PWR/BWR reactors would also use water as a cooling source.

  14. Re:Doesn't matter on In Hot Water: The Effects of Even Modern Nuke Plants On Water · · Score: 5, Informative

    The ironic thing about this situation is that the entire problem could be solved (especially for newer reactors) by building cooling towers rather than using rivers for cooling.

    Uh, no. Even if I hadn't RTFA I'd know you are wrong. Cooling towers are built to cool the water through evaporation, and said evaporation (and blowdown) of the proposed "closed-loop" cooling system is what TFA was complaining about, since none of the water taken would be returned to the river.
    Also, a lot of cooling towers are built precisely to cool the used river water before returning it to the river, so, because of evaporation, they not only return less water to the river than taken, because the river is lower temperature than the typical ambient wet bulb temperature, what they return is warmer than the river (unless you had a really unusually hot river).

    However, is there some kind of water shortage problem that we actually need to resolve? Unless we plan to pipeline water from Kansas to Boston I doubt that use of water in the one area has much effect on availability of water in the other.

    To put that in perspective, the current levels are around 339ppm. If you are not good at math, 6000 is more than 10 x 339.

    Not to challenge your main point, but current CO2 levels are above 380 ppm and at the present rate of increase, they will be above 400 ppm in a few years. Also, if the levels were above 6,000 ppm, that would cause a lot of serious health problems for people.
