Comment And the original AC is wrong. (Score 1) 174

What original AC is saying is that our current medicine doesn't resemble Star Trek style ... We drop blanket bombs into our bodies with the expectation that the evil bits will die a whole lot faster than the good bits, and by the time the evil bits are dead, the good bits are still in a good enough shape to regenerate.

No that is NOT what we do for practically anything but chemotherapy for most cancers (where the difference from normal tissue is very small - a few mutations in signaling systems) and the main difference is that being stuck in reproduction mode makes them somewhat less robust.

Antibiotics are all about targeting one or another chemical mechanism that has one form in the target organism when its equivalen has another - or is absent - in human tissue. There are a LOT of drugs that have been discovered or designed, and the collection consists of enormous numbers of "magic bullets" that each target just one, or a small set, of systems found in particular pathogenic lifeforms, with either negligible, or far lower, side-effects on other systems.

Sure many antibiotics hit a wide range of NON-human life - pathogens and others - because THEY share susceptable versions of the target system or contain systems that are strongly side-effected. Sure the doctors sometimes have to pick drugs with bad side-effects because those are the best choices they have. But the characterization of antibiotic and antiviral drugs as "blanket bombing" has been out of date for more than half a century.

Comment Re:Taste like chicken? (Score 1) 107

Recent research has shown that chickens are the closest living relative of T. Rex.

Do you have a reference for the research?

If it's true that T.rex is closer to chickens than to pheasants, peafowl, and other Phasianinae, it would mean that the Phasianinae family dates back to before the K-T disaster.

This was all over the mainstream press last April. I was echoing their over-simplified characterizatoin of the research.

It's actually "closest living relative among the set of genetic databases they tested", I.e. chickens, sheep, etc. Chickens happened to be a bird they tested, with aminno acid sequences far closer to those of the collagen recovered from T. Rex - nearly identical, in fact, than those of things like mammals. So don't expect this to re-write taxonomy - or to mean that chickens were any closer - or farter - from T. Rex than their close relatives such as phesants.

Of course there's other evidence that birds were around well before T. Rex. So it may turn out that chickens are closer relatives to T. Rex than, say, bluebirds. (Or maybe bluebirds will turn out to be closer, once they're compared.)

... give the patient more time to produce his own antibodies. ... the experimental treatment used on some western patients is basically antibodies.

Right on both counts.

  - Much of why Ebola is so often fatal is that it produces a glycoprotein that interferes with immune system signaling, reducing and delaying the immune system's antibody-mediated specific responses. (Meanwhile the cell damage and foreign protein stimulate the GENERAL responses, which causes self-damage to the body and aids in spreading the infection.) Details on Wikipedia Keeping the virus population and the glycoprotien concentration down by supplying ready-to-go antibodies holds down cell death from infection, self-destruction, and signaliing interference, giving the immune system more time and ability to respond.

  - The drug in question is a mix of three monoclonal antibodies, manufactured by stock genetic engineering techniques.

Injections of extracted antibodies, or blood containing them, has a long history in medicine. They have been used against bacteria, viruses, and poisons such as snake venom. Typically they are made by extracting a blood fraction containing antibodies from an animal which has been recently immunized - and is currently hyper-reactive to - the target disease agent or venom. (This gets a load of mixed antibodies which is heavy with those specific to the target.) They may also be extracted from a human survivor of a disease of interest, or a human in general. (These you might hear being called "human imune globin" or "gamma globulin".)

Downsides include allergic reactions to the animal used (typically a horse) or person providing the globulin, infection with blood-borne diseases (such as Hepatitis C), and reaction against the patient by some antibody in the serum.

Antiseura fell out of use for bacteria with the rise of antibiotics (even for diseases, such as menningitis, where antiseurm treatment had higher success rates). Antiviral drugs and the rise of a number of human viral diseases are pushing it down in preference for viral disease treatments - though better blood tests for viral infections is improving its safety. Nothing, of course, has replaced it for antivenom. It's still used for things like Hepatitis A, Measles, rabies exposure, supplement for certain immune difficiencies, and modulating immune system rejection of liver transplants.

With both the rise of antibiotic and antiviral drug resistance and the development of monoclonal antibody culture (prodcing just the desired antibodies to a target on an industrial scale, with negligible risk of dangerous contamination), expect more use of antiseura in medicine - like this "new experimental ebola drug".

Meanwhile, using antibodies extracted from ebola survivors - or transfusions if a matching donor is available - is the same system and might work just fine. And the technology is simple and cheap enough to be available even in third world countries.

Of course you need to wait until the survivor has recovered enough to have built up antibodies and enough blood to spare. Ideally you should also wait until the virus has cleared. (For instance, with Ebola, semen remains infective for at least two months, so blood likely does. as well.) But if the patient is already infected and likely to die without treatment, that's not an issue.

because the broken window fallacy still holds

Indeed.

Using the Obama administration's own numbers, a couple years back, for how much they spent for each job "created or saved", and taking the US median income at the time for the cost->jobs destroyed estimator, I got about a 5:1 ratio. Five destroyed for each "created or saved".

Or more: Thats what would happen if they got the money by taxation. The other options are still worse.

The problem is that the VALUE for the government spending comes out of the economy somewhere else:
  - If they tax it, they just suck it out directly.
  - If they borrow it, it competes for investment money and real job creators don't get to create real jobs and/or have to close or downsize when their funding dries up. (This has an additional multiplier: They have to pay it back, with interest. So it kills still more jobs later.)
  - If they print it, it devalues the other currency. The same number of dollars are spent, but less value is spent. Less jobs are funded as a result.

Unfortunately, the anonymous flaimng lefties only see the obvious jobs "created or saved" and not the "invisible men" laid off or not hired as a result.

There is no reason the design of a waste hauling train should wait until a site is identified, thus delaying the removal of the waste from many scattered temporary storage sites. The hauling design and the site identification can proced in parallel.

Indeed: The characteristics of the hauling solution may limit the selection of sites to which the waste could be hauled with acceptable levels of safety. That would argue for the design to PRECEED site selection.

I still have several machines that interchange mail with each other and the Internet via uucp mailnet. I poll an ISP twice an hour (or use an alias to force a poll if i don't want the mail to wait.)

I even check my personal mailbox on that domain every couple months. (Every three weeks or so I get another offer to buy my domain name, which has been around since the list of machines that exchanged email fit on three typeset pages.) But you wouldn't BELIEVE the amount of spam that accumulates on an account that has been around since before the first mass mail-merge spam scripts were offerd for sale. (I think I still have a saved copy of that original piece of spam - advertising spam software.) The spammers STILL include that address in their mailing lists.

If the NSA or ISIS ever kills the connected Internet, UUCP mailnet will still work, merrily bucket-brigading email among the hadnful of machines whose mail transfer agents still interconnect by routes that don't just hand the mail off to an Internet hop.

Also: Back when we ran mailing lists over UUCP, the polling delay limited the deluge of mail when someone on the list accidentally forwarded his mail to the list. This gave us time to catch it manually and suspend the account before everybody was buried in repeated messages. B-)

vi for me, too.

Not that I have anything against emacs. But I bought my first unix computer in the 80s, and it only had two megabytes of RAM and used an early member of the 68xxx series that couldn't do demand paging to act like it had more. This was too little to compile and run emacs.

After about three years of heavy bulletin-board participation I had the vi commands "wired into my brainstem". I tried emacs several times over the years and each time discovered that certain common things I did (and still do) with vi took about twice as many keystrokes.

Once I tried using its vi emulation mode - only to discover that it (the version at the time) had TWO of them, in true emacs kitchen sink style, and each had different deltas from getting the vi commands right. With only one I might have gone on to use it, and learn the deltas, while edging into native commands. But with two, and no obvious selection, I didn't bother.

Nowadays I use vim, which is close enough. (Especially if you tell it to act like vi in a couple important places.)

This is going to go no where unless he can get an independent expert to certify that his measuring technique is accurate.

We're talking small claims court here (where proceures are much more relaxed due to the small amount of the dispute) and civil procedure (where the standard of proof is "preponderance of evidence", not "beyond a reasonable doubt".

Also: A suitable expert shouldn't be THAT hard to find, and (with open source and things like the Raspbery Pi and Beagle Bone available for platforms), independently engineering a meter to check the first one should be quick work - and something a customer of another ISP might want to do, as well.

Heh. Once it's done it could be published open-source, bringing the tool into the hands of the technically-literate masses. A couple thousand small claims cases a month might be more effective than a class action suit for getting their act cleaned up.

The Arthur C. Clarke sci-fi novel "The Songs Of Distant Earth" (1986) used the Case Of The Missing Neutrinos as the opening premise [followed by "the sun is about to nova" and humanity having] a few hundred years to develop interstellar-travel technology before the Sun went nova. 'Twas a good story.

Indeed it was.

In mine, though, there was nothing wrong with the sun at all. It's just that the high neutrino flux makes other physical phenomena more apparent and (by book three) usable at a practical level. FTL interstellar travel IS developed by the fifth book (when things are fully sorted out), which is in hard science fiction space-opera form.

Of course, by that time "magic" is hard science (though its engineering is more like animal husbandry), religion has merged with psychology, and one of the crew members (or is he the FTL engine?) is (and must be) a literal god. (For the engineering crew chief think "Scotty in Druidic Robes"...) Using a god plus a nuclear reactor for the engine leads to complications (but not the ones you're probably thinking of right now).

No, not like Clarke's story at all. More like Keith Laumer collaborates with Larry Niven. B-)

Take them to small claims court.

Ask for the difference between the billing tier your meter says you should be in and the one they charged you for. Dump your data in a reasonably clear format and show and explain it to the judge. Be prepared to swear that it is correct.

If they overcharge you next month, do it again.

Keep it up until they fix the meter so the agreement is close enough for you to be happy with it (or until the judge gets tired of it and issues an order - either to you or them - to make the cases stop.) It's not barratry - no matter how vexing to the utility - if the suits are legitimate, with real grounds asking for restitution for real damages, nor if the the suits are repeated because there are new instances of the tort.

First time through, ask for all the months for which you have data that shows overcharging. (If you can demonstrate a rule for the systematic overcharging, ask for the overcharges back to the instalation of the system, but be prepared for the judge to reject that.) Up to the small claims price and time limits, of course.

Be polite to the judge. Assume he's smart enough to understand this if you explain it clearly. (Judges don't get to be judges without being smart and good at figuring these things out.)

Comment That almost happened a while back. (Score 2) 141

The other interesting result would be if the expected neutrino type was not detected by this experiment, invalidating the hypothesis. This would raise further questions such as: is there some other mechanism powering the Sun? Is there something deficient in our understanding of neutrinos that prevented us from detecting them despite them being there?

That almost happened, in the early days of neutrino dectection - before things like old mines full of purified water and 3-D arrays of photodetectors running for months at a time, and you could count the number of detected neutrinos on two hands (in bi-quinary so you could go a bit higher than ten). This was when the detectors could only detect the type of neutrino directly generated by fusion reactions, and before the discovery of neutrino oscillation, when it wasn't yet clear whether neutrinos had no, or very very little, rest mass.

Early numbers, and their error bounds, made it clear that there weren't enough neutrinos being detected. (This was known for years as the "missing neutrino problem".) But the earliest ones WERE about right for a situation where all the stars EXCEPT the sun were running by fusion and the sun was out.

That may sound odd. But there was a very cute explanation that made it plausible:

The gradual gravitatonal collapse of the sun, as heat is radiated away, could power it for millenia. It's nowhere near enough to power it long enough to explain the fossil record, but it IS enough to have kept it running for historic time. Meanwhile, if a fusion reaction were to start up near the center of such a ball of collapsing gas, it would also take many years for the heat to make it to the surface. Neutrinos (which go through the sun like marbles through a light mist) are about the only signature of what's going on in there NOW.

But suppose, instead of fusing continuously, stars were reciprocating engines. They might run without fusion for centuries, or millenia, until they were compressed enough to "light up" at the center. Then the fusion heat and reaction products might make the reaction ramp up. They'd burn for a little while (which would heat them up and expand them mabye a few inches), until the decreased density and/or reduction in fuel and/or accumulation of reaction products "put the fire out" again. Repeat for the life of the star.

In this scenario, if our sun happened to be between "putts (and the very nearest stars didn't happen to have an unusual distribution of where they were in their cycles), you'd see the same neutrio flux from the rest of the sky as if all the rest of the stars were running continuous fusion. That's because it's the average of stars that are "on" and "off", and comes out to the same amount of total fusion and neutrinos.

Of course later data, both larger samples and detectors that could "see" the other neutrino types, put the kibosh on that model. A big part of it was the discovery of neutrino oscillations, allowing a stream of neutrinos that started out as one type in the sun to arrive as a mix of the three types. (This means that neutrinos have a non-zero rest mass, fly slightly slower than light, and thus experience time and are ABLE to change from one type to another.)

But, again, neutrino oscillation can't nullify these results, because oscillation only makes neutrinos harder to detect (by changing their "flavor"). It doesn't create neutrino signals where none originally existed (at least not in this sense).

Sure it can: By "oscillating" other flavors of neutrino into the type they're looking for, when they weren't there in the first place (or not in sufficient number).

They'll need to look at the ratio of the various types and back-calculate to eliminate other possible signals, or combinations of them, to see if there is a way for other (possibly unexpected) reactions to produce a signal that looks like the ones expected and/or observed.
