Take arthritis for example; it's caused by joint cartilege having been worn away over years, faster than it could heal.

    Most chronic diseases are the result of age-related damage (arthritis, atherosclerosis, dementia, others), or have ultimate causes which are not understood (asthma, allergies, chrohn's, alzheimers, rheumatoid arthritis, others), or are genetic (tay-sachs, others). Those diseases could not be cured by a drug. No small-molecule drug could selectively repair genetic defects, or regenerate lost tissue in the correct places to youthful levels. Drugs can only interfere with ongoing biological process, and as such can only slow down or halt disease progression, or interfere with symptoms.

  2. Re:The dissenting opinion on US Nuclear Power Industry Poised For a Comeback · · Score: 1

    Thanks for your thoughtful post. I'm glad someone had the courage to dissent and to do so intelligently.

    With that said, I will disagree with a few things you posted.

    The fact remains that the world has a growing stockpile of material which requires careful storage and monitoring for hundreds of thousands of years.

    Nuclear waste loses most of it's radioactivity fairly quickly. It loses 99.99% of its radioactivity within 500 years. After which, the remaining waste is so weakly radioactive that it's comparatively benign. After 500 years, the radioactivity from the waste is so weak that the primary danger from that waste is heavy metal poisoning, not radiation. In other words, after 500 years the waste is a health hazard similar to mercury or lead, except it's buried under a mountain in casks.

    None of this cost is calculated into the cost of price of electricity generated.

    The cost for permanent storage of nuclear waste is imposed on the industry as a surcharge. That surcharge paid for Yucca Mountain and will pay for the next permanent storage facility, although it will take some time to save up enough money again.

    I find it unconscionable that we are willing dump such a tremendous problem in the laps of our children

    Our children would be totally unaffected by a single small area of radiation buried deeply within a single mountain in the middle of a remote arid desert.

    Solar and wind ARE sufficient to take care of our energy needs,

    Solar is nowhere near to being cost-competitive.

    Wind is fairly cost-competitive, but only if it's accompanied with natural gas plants for when the wind isn't blowing. Those natural gas plants still emit carbon dioxide. Granted, the wind+gas combination would reduce CO2 emissions by about 80% compared to a coal-fired plant. However, the remaining 20% CO2 emissions are still far more damaging than nuclear waste.

    Don't get me wrong, the wind+gas combination is much better than what we're doing now, but it's not the best option.

  12. Study relies on absurd assumptions on Wind and Sun Beat Other Energy Alternatives · · Score: 3, Insightful

    This "study" is not really a study, but a model. As such, it's only as good as its assumptions. Unfortunately, many of its assumptions are completely wrong or totally implausible.

    For example, the model predicts that nuclear power emits 25x as much carbon as wind power. You may wonder how that could be possible. It's possible because that conclusion follows from the model's assumptions which are all wrong, as follows.

    First, the model compares the carbon output of new windmills, versus the carbon output of obsolete ways of refining uranium as an average over the last 40 years. Since refining uranium is far less carbon-intensive than it was, we should use the new figures only. It does not matter how much carbon was emitted by uranium enrichment for plants in the 1960s. Nobody is suggesting building those. We are debating whether we should build new nuclear power plants, or new windmills. As such, we should compare the carbon output of new uranium enrichment against new windmills. In this case the author clearly commits the "sunk cost fallacy", and the assumption is totally wrong.

    Another mistaken assumption behind carbon emissions of nuclear plants, is carbon emissions from delays in plant constructions. The author assumes that nuclear power plants will take 10+ years to construct, and in the mean time, we will continue to generate electricity by burning coal. On the other hand, he assumes that the delay associated with windmills is "zero". However, that assumption is totally wrong. Windmills will lead to "zero delay" only if the United States throws away every coal-burning plant we have and replaces them with windmills this year. Since that will never happen, the assumption is wrong. In actuality, those coal plants will be decomissioned at the end of their useful lives and will be replaced by either wind, nuclear, or something else. So, the delay associated with nuclear or wind would probably be quite similar. Since this factor alone accounts for most of the "25x as much carbon" which nuclear is said to produce, that figure is refuted.

    And there are other assumptions which are wrong. For example, the model assumes that nuclear power will lead to nuclear weapons which will cause a nuclear war with a resulting environmental catastrophe. Since nuclear power cannot be used to construct nuclear weapons, this assumption is mistaken. Unfortunately, the author makes many errors when he discusses the relationship between nuclear power and nuclear weapons. In actuality, nuclear power has almost no probability of starting a nuclear war.

    The paper states that "Worldwide, nine countries have known nuclear weapons stockpiles (US, Russia, UK, France, China, India, Pakistan, Israel, North Korea)" and shortly thereafter concludes that "Thus, the ability of states to produce nuclear weapons today follows directly from their ability to produce nuclear power". But that is entirely wrong. It's a spurious correlation. The reason some countries have nuclear power plants, and the same countries have nuclear weapons, is because those countries are technologically advanced, which causes both nuclear weapons and nuclear power; not because nuclear power causes nuclear weapons.

    And there are other assumptions about nuclear (not related to carbon emissions) which are equally unrealistic. For example, the model claims that nuclear "produces fuel rods that are usually stored on site for several years in cooling ponds pending transport to a permanent site" and somehow concludes that nuclear has as much of a detrimental effect on wildlife as coal power. I honestly have no idea how he derived that conclusion (he doesn't say). It seems to me that mass strip-mining of the countryside (including mass-strip mining for serpentine rock if we intend to use that for mineral sequestration) every year, would greatly outweigh nuclear power's single kilometer of radioactivity buried deep beneath a single mountain in an isolated arid desert in Nevada, once.

The assets will be purchased at a price higher than the market will pay for them right now; probably they'll be purchased for around $0.35 on the dollar. When the assets are re-sold, if they have lost value, then the gov't automatically gains a large equity position in the company which originally held the assets in order to offset the loss (the gov't gains warrants in exchange for buying the crappy assets).

    This plan would not cost anywhere near $700B. Since the plan would purchase assets for $700B that have a non-zero value, the plan would ultimately cost a fraction of $700B, realistically $50-200B.

    I have read through various polls now, where pollsters contacted random people in the population and asked them their opinion about the bailout. None of the people contacted held anything like a correct idea of the bailout. All of them thought something like: "we're going to SPEND $700B of MY money and GIVE it to wall st fat cats who caused this mess in the first place?!?!?!".

That has two implications: 1) lowering the fed funding rate no longer has any effect whatsoever; 2) the interest rates on practically every ARM in this country went up by 2% on that day, as well as the interest rates on many credit cards, student loans, and so on.

    We have a heavily indebted population. If the interest rates on their debt remains at elevated levels because of a credit crunch, then the cost of that to our economy would greatly, greatly exceed the fraction of $700B that a bailout would cost.

    Not to mention, we have several heavily indebted corporations that will not survive a credit crisis (like ford and GM, probably). Some of those corporations will not have access to lending and will go under, all at once, triggering a severe recession with higher unemployment. The cost of that would be far higher than the fraction of $700B that the bailout costs.

I'm not necessarily endorsing the Paulson plan, and I'm not saying that any plan has to be passed this very day, and I'm not saying we should just hand Paulson $700B with no oversight.

The chances of them having even one invention worth patenting is probably close to zero. A one-year-old company should focus their scarce money on generating intellectual property and should have at most one or two patents; and those patents were probably created by the founders.

    Drug patents are not analogous to software patents. Drug patents cost hundreds of millions of dollars to develop and bring to market, so they are worth protecting. The amount of money invested per drug patent is immense, so a patent is reasonable.

Most patents will not yield enough money to recover the $5000 spent on incentivizing the employee, to say nothing about the many thousands spent on patent attorneys.

    I would also have grave concerns about any company that focused on patents. In almost every such company I've dealt with, they did not have any intellectual property worth patenting. It is an absurd presumption for any company that they will turn out discovery after discovery which warrants protection, or that they will turn out discovery after discovery if they institute an incentive to do so. Instead of worrying about patents, their concern should be having one discovery or one program that is worth anything at all. If they manage that, then they'll be ahead of 90% of startups. But if they concern themselves with protecting intellectual property rather than generating it then they're in big trouble.

    However, if the company is insistent on offering incentives for patents, then it should offer incentives based upon how much money others will pay to license the intellectual property and use the patent. If the amount others are willing to pay for a given patent is "$0" (most likely) then the incentive to employees should be nothing.

    In other words, if they offer a monetary incentive per patent, then the employee is paid to produce any kind of patent. The idea is absurd. Happily, the USPTO no longer accepts patents for perpetual motion machines, otherwise I as an employee would generate 20 patents just for that.

When symptoms appear, this process of exponential growth is already 95% complete and the organism will soon be dead. At that point, the organism is much more infectious because the number of prions is far higher than originally.

    Because prions replicate themselves, they bio-accumulate over time. Since organisms can "inherit" the prions of other organisms by ingesting them, the prions can accumulate across generations.

    How can a company with $24B in sales, $3B in profit, and $40B in cash and assets (2007 figures) have a market cap of $160B?

    Actually, Apple has $4.6 billion in profit.

    Usually, market caps are much greater than yearly profits. If they were the same, then that would mean the investment could yield 100% per year in earnings, which is much higher than usual.

    Right now, Apple would pay about 3% per year if they distributed all their earnings as dividends to investors. That figure isn't very high, so why is Apple's stock price (and market cap) so high?

    Apple's stock price is high because wall street expects that Apple's profits will increase substantially in the future. The high stock price is based on anticipated future returns. If Apple were a "no-growth" company then it's market cap would be about half what it is.

    (If you subtract the cash and assets from the market cap, you have $120B, which is what wall street thinks the risk-adjusted discounted net present value of all future earnings from Apple will be. Wall street expects those earnings to increase.)

    I'm not sure I would invest in Apple at current prices. I'd rather put my money in intel or even microsoft.

    The difference between Microsoft and Apple, is that Microsoft is seen as a NECESSITY for business, whereas Apple's products are seen as COOL. But cool is fleeting. I could see young people dropping their iPods 5 years from now the same way young people dropped acid-washed jeans, Doc Martens, and Walkmans. But businesses will never drop Wintel. Never.

    I'm not sure that the risk of "suddenly uncool" has been adequately factored into Apple's share price.

    Apple is also larger than oracle, sap, and cisco, and nearly as large as IBM. The only tech company larger than Apple by any significant margin is Microsoft; but even then, Apple is more than 60% as large as Microsoft and is growing considerably faster.
