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 But the characterization of antibiotic and antiviral drugs as "blanket bombing" has been out of date for more than half a century.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.

Too bad the drive died. I know how that feels. Norton Ghost saved me once.

There are some solutions though, including placing the drive in the freezer for a couple hours and trying again. Though, a search just found this that warns against it.

On a side note, i have mod points. Should be coming to a JE near you. (Someone seems to have modded us all up recently as it is.) Everyone, please point me to your posts even if your rating isn't less than stellar.

Pandering to the public seems so fickle. Popular today means it'll require changing tomorrow.

Is the constant change really helpful, or are these studies done with blinders on, looking only for short-term gain?

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.

WD basically invented the hard drive and used to be awesome. Then they started selling garbage. After having a number of their drives fail and seeing online reports of the same, i no longer consider them an option. Same story with Epson for printers. It make me wonder why these great companies decided to destroy the one thing they had: A brand that stood for quality.

Comment TFA betrays Ray Henry 's ignorance of planning. (Score 5, Insightful) 258

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.

Comment UUCP Mailnet (Score 1) 635

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-)
