First, guns don't protect, never have, never will.
The first eight of your 457 word wall of text shows you're so out of touch with reality that there's no point in reading the rest.
The primary function of guns in private hands is to protect those who carry them. They do that exceptionally well. In criminal attacks, resistance with gun is the most effective way to avoid injury or death. It's substantially more effective than the second best - knuckling under completely - and beats the pants off everything else, from running away, to trying to talk your way out, to resisting with bare hands or other tools. (Resisting with knife is about the worst.)
Research on self-defense is hard, because faiures leave tracks in crime stats while successes usually don't (and often leave the self-defended victim with an incentive to keep quiet about it). Nevertheless, even the first well-run projects were able to put a lower bound of guns preventing or aborting more than six times as many crimes as they aid in committing.
In private hands they're safer than police, too. A defense-with-gun is usually effected by no more than brandishing or occasionally getting off a round in the general direction of the perp. But of those instances where a victim or a policeman shoots someone believed to be a perpetrator, the cop is over 5 1/2 times as likely to erroneously shoot an innocent than an armed private citizen.
My family has substantial personal experience with armed self defense. For just a few examples on my wife's side: In college she was accosted by the rapist in the window, who was dressed in just running shoes and a dirty knife. Fortunately there was a hunting rifle behind the bed: She actually had to go as far as cocking it before he stopped trying to get her to drop it and jumped back out the window - apparently to take it out on another girl a few blocks away, with over 130 cuts while raping her. Her mother defended self and family against a Klan attack with a pistol. (Her granddad was caught away from his gun, though, and had to do his anti-Klan defense with a hammer.) Then there was the aunt, the uncle,...
At the larger scale it's hard to argue with the fact that the US, founded in a revolution (by religious nut with guns) against their self-admitted "legitimate government" and with over half the adult civilian population armed, has now gone over two centuries without a substantial attack from abroad and only one major internal war, while Europe continues to suffer from genocidal wars, often with multi-million body counts. (With the exception of Switzerland, of course: Every adult citizen there is armed and has had military training. Even World Wars go around them.)
It's also hard to argue with the fact that the US is multi-ethnic, and the common denominator of each of its ethnic groups is that their members' murder victimization rate is substantially less than that of contemporary members of the same ethnic group still residing in their land of origin.
As for resisting an oppressive regime if push comes to shove: We have experiences like "The Battle of Athens" just after WWII, and the documented question from Nixon to a thnk-tank about what would happen if he suspended the presidential election. (Answer: That would precipitate an armed rebellion, and the population was well enough armed that it would succeed.) Uprisings aren't always successful and small or UNarmed uprisings are often put down, sometimes with lots of deaths. (Witness the Bonus Marchers' Massacre.) But recent decades of world politics have shown how effective a popular uprising can be, against even a coalition of world powers and superpowers.
If it came to that in the US, you can expect a substantial amount of the military (especially retirees) to be on the side of the people, along with lots of military equipment raided from armories. (You can see that now in the Middle East. The big difference between Al Queda and ISIS/ISIL is that the latter has bunch of col
However, the Ebola Reston strain is airborne though only dangerous to monkeys.
I have oftten wondered whether the Reston virus had mutated to be spread by things like sneezes, or if it might be another matter entirely.
A number of monkey species throw feces (and/or other bodily secretions) when under stress and perceived attack. (I don't know if this is one of them, but assume for the moment it is.) Might being confined to cages along with others provoke such behavior? Wouldn't a sick monkey's feces, and tiny particles separated by airflow during the flight, carry an ebola-family virus just fine, without any mutation to make it, say, shed into nasal mucus and be carried by a sneeze?
(Granted this might fit the literal definition of "airborne transmission". B-) )
3D printing was the result of a lot of researchers working on a lot of parts, and when the dust settled, none of them could build a really practical printer without paying off all the other patent holders, most of whom were playing dog-in-the-manger with their patents while trying to elbow out the competition.
You see that with a lot of inventions. They may go through several cycles of invention / related invention / non-conbination / wait / patent expiration until enough necessary parts of the technology are patent-expired that the remaining necessary inventions can be assembled in a single company's product and the technology finally deployed.
Thermoacoustics, for instance, just had its second round of patent expiration and is in its third round of innovation. The basic idea is to make a reasonably efficient heat-engine and/or refrigerator (or a machine that combines, for instance, one of each) with no moving parts except a gas. Mechanical power in the form of high-energy sound inside a pipe is extracted from, or used to create, temperature differences.
There are some really nice gadgets coming out of it, built mainly out of plumbing comparable to automotive exhaust systems and tuned manifolds, maybe with some industrial-grade loudspeakers built in, or their miniaturized or micro-minaturized equivalent. (Example: A hunk of pluming with a gas burner, about 12 feet high and maybe eight feet on a side. Oil fields often produce LOTS natural gas in regions, like big deserts, where it's uneconomic to ship it to market. It gets burned off and vented. (CO2 is weaker greenhouse gas than CH4, by a factor of several). Pipe the gas into the plumbing, light the burner, and it burns part of it to get the power to cool and liquify the rest. As a liquid it's economic to ship and sell it. Then you get to use much of the otherwise wasted energy, displacing other fuel supples and reducing overall carbon emssion.
I hope this is the cycle where things hit the market.
Patents don't matter for making a printer for your own use.
They can matter if you build a business on them, like by selling objects built using them.
Especially if they improve make your process cheaper, easier, more convenient, flat-out possible, or produce a better part. (And if there ARE cheaper, etc. ways to do it, why are you using the patented tech anyhow? B-) )
Patents in the US were about increasing innovation by making first mover advantage truump second mover advantage: Giving the little guy with the bright idea time to set up manufacturing, make back his costs, reap some benefits, and get established enough to compete with existing large companies once they expire. Without them, it was thought, the existing big guys with the infrastructure in place could quickly clone the little guy's new invention and out-compete him in the market, but they wouldn't bother until the little guy had proved it was worth the effort. This would suck the incentive out of the little guys, the big guys would have little incentive to improve, and progress would be slow-to-stalled. The short-term inhibition on others deploying the invention was seen as less of an impediment to progress than having most inventions not be deployed, or even made, at all.
The idea was to set the time limit to maximize progress to the benefit of all/the country, and make manufacturing and technology grow like yeast (ala silicon valley B-) ). Part of the intent was to bias it toward innovators and make established processes free to use, because when the country was getting started the established players were owned by foreign interests. The founders wanted the country to develop its own industry, rather than being dependent on, and sending most of the profit to, big businesses in Europe.
But the time was set for heavy manufacturing at the pace of the period. It's a horrible mismatch for, say, software: With the availability of general purpose computing platforms, able to make distributable copies at electronic speed and copyright to prevent verbatim cloning, a person or company with a new software product can go from steath-mode program development to market establishment, profitibility, and even market dominance in a matter of months, before competitors can engineer their own version. So patents aren't necessary to promote innovation, leaving just their retarding effect holding down the blaze of creativity. (Then there's open source, with its alternitive monitization and/or reward strategies. But that's a "new invention". B-) )
It seems to me that:
- The expiration of patents on stereolithography did help produce the initial explosion of new, and often inexpensive, devices and the improvements in what can be made, how accurately, and how inespensively.
- The availability of machines suitable for practical industrial prototyping - even before the cheap machine explosion - pretty much forced the high-end CAD software producers to include some form of stereolithography output format, while an open output format made the choice obvious. That's a big benefit to the toolmaker for a small effort. The availability in the high-grade commercial tools is a great synergy and helps a lot. But the hobby machines needed CAD tools and open source was already up to the task: Had the big players not gone along it still would have been done, and those big players not "with the program" would be experiencing major competitive pressure from open source tools and competitors that did provide such output.
And here's the key:
- The availabitiy of these rapid general-purpose maufacturing tools will bring (is already bringing!) software's high-speed innovation and entrepenurial models to the manufacture of physical objects. Patents could be shortened in term or reduced to "design patents" - the manufacturing equivalent of copyright - and produce a physical-product explosion comparable to the computer revolution. (Or patents, like "content" copyright, could become the tool of obsoleted established players in the suppression of the competing business models.)
Brace yourself for either the physical-manufacture ramp-up to science-fiction's "singularity" or an ongoing RIAA / MPAA / conglomerate - style legal battle.
A dollar capital cost per kW of generation (with a couple decades lifetime minimum) is the ballpark for the breakeven point between grid power and solar generation on mid-US-latitude sunny sites (5ish solar hours/day), with grid power available.
Being remote (so running grid is pricey) or having a small load (so basic connection fees aren't justified) shifts the point to higher dollars/watt, as does an increase in utility rates. Shade, dark weater, and high lattitude shifts it downward. (Forget about solar in Seattle, for instance.)
Solar panels are just starting to drop below $1/W, making them practical in far more places, and making the load size and associated system costs (mounting, inverters, storage) more of a factor.
Over $/W? It needs some exceptional situation to compete with cheap flat panels.
The headline says farmers. The text says farm workers. Very much not the same thing. A farmer is the owner of the farm. A farm worker is generally a hired hand, often (though not always) a migrant, and if so typically from Mexico or farther south.
The story suggests that the multi-drug-resistant bacteria are the result of antibiotic treatment of the animals at the farm. This misses another possibility:
In Mexico, most antibiotics are over-the-counter, much like asprin here in the US. People who feel ill or have some infection often buy and take them. Typically they use them until they no longer show symptoms - then stop, rather than taking a full regimin and killing off all the bacteria. (Why take more of the non-free drug once the symptoms are gone? Waste of money, right?) This is a recipe for creating drug-resistant bacteria.
Of course if an infection is resistant to one antibiotic, a paitent is likely to try another, and another, and so on until they find one that works. THAT's a recipe for maintaining and improving the bug's resistance to the front line antibiotics while breeding resistance to others.
As a result, a substantial fraction of the workers arriving from south of the Mexican border are carriers of multi-drug-resistant baceria.
Meanwhile, a farming operation is likely to give a limited number of antibiotics continuously, so non-resistant infections are wiped out before they can develop resistance, and if they do develop resistance it will be to the particular drugs used, rather than the universe of antibiotics.
Of course, infected workers can infect livestock, just as livestock can infect workers. And infected workers can trade infections around, just as livestock can. (More so, since the livestock tends to be kept separated, to reduce both disease spread and breeding by unintended pairings, limitations that farmers can't impose on their workers - and would be unlikely to try even if they could.)
So it seems to me that responsible researchers would go a bit farther before reporting: Like by doing genetic testing on the strains of bug in the various workers and the livestock, and running models on the results to try to identfy whether the bugs are from the herd or the workers.
I don't see any such work alluded to in this popularized reporting. It seems to just assume that the bugs were developed on the farm and spread to the workers. I hope this is a disconnect between the actual research and the report, rather than an accurate characterization of the research.
The gas bag itself was flammable; it wouldn't have mattered what gas was in it, when it disintegrated
In particular: The paint. It contained a mix of powdered aluminum and iron oxide pigments, in sufficient concentration to maintain a redox reaction.
You and I know this mixture as "thermite". It's really hard to get the reaction started - but an electric discharge can do it. (They tried to tether it with an electrical storm approaching. That would make one hell of a spark when the charged envelope comes near to connecting to the grounded mast - which is about when the fire started.) Once it's started, the reaction is essentially impossible to extinguish. The aluminum steals the oxygen from the iron oxide. The heats of formation of the two oxides differ so much that the energy released leaves the resulting elemental iron as an orange-glowing liquid and the aluminum oxide incandescent white-hot.
You are bound by the treaties your country signed.
Yes: You, and the states, and their courts, are bound by them (to the extent they are clear or were implemented by federal enabling legislation).
In fact, they have more legal weight in the US than laws passed by your own Congress.
NO! They have EXACTLY the same weight as federal law. Both treaties and federal law are trumped by the Constitution, and both are also creatures of Congress, They can be modulated, and destroyed (at least in how they are effective within the country) by congressional action.
The idea that they're any stronger or more permanent than federal legislation comes from a (very common) misreading of the Supremacy Clause:
This Constitution, and the Laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the constitution or laws of any state to the contrary notwithstanding.
This says that the Constitution, Federal Law, and Treaties trump state law in state and federal courts. It says nothing about the relative power among the three.
The misreading is to interpret "all treaties made... shall be the supreme law of the land..." to mean that treaties effectively amend the constitution. This is wrong. You can see it by noticing the same kind of misreading also makes federal law equivalent to a constitutional amendment - which it clearly is not.
In fact the Supreme Court has spoken on the relation between the Constitution and treaties: In Reid v. Covert, 354 U.S. 1 (1957), the Supreme Court held stated that the U.S. Constitution supersedes international treaties ratified by the U.S. Senate.
Treaties are abrogated, at the federal level, all the time, and there are a number of mechanisms for doing so.
Now they have the guide printed on the box but I can remember when i was a kid they didn't.
Some off them had maps at least as far back as the '50s, and probably much further.
A classic was the "Whitman Sampler" - an assortment of their products with a handy map. In addition to being a tasty and relatively low-priced collection of their products, it let a family divide them up according to their individual preferences, and gave you the names of each, so you could (at least hypotheically) buy boxes of just the ones you like.
(I say hypothetically because I never saw boxes of the individual candies being carried in the stores that sold the samplers.)
But regardless of the pressure, when the helium leaks out, it will not be displaced by air. It will leave behind a vacuum. The helium will leak out, but nothing will leak in to replace it.
(Except maybe hydrogen, but there's not much of that in your local air.)
So your metal parts vacuum-weld and tear themselves apart starting at the contacting surfaces, and adding lots of hydrogen to the air around the drives just makes the parts become brittle on their way to failure.
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.
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.

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-)
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.

Seems like a big flock of pigeons over a big crowd would be an effective way to spread a virus that is contagious between birds and people.

Without them, it was thought, the existing big guys with the infrastructure in place could quickly clone the little guy's new invention and out-compete him in the market, but they wouldn't bother until the little guy had proved it was worth the effort. This would suck the incentive out of the little guys, the big guys would have little incentive to improve, and progress would be slow-to-stalled. The short-term inhibition on others deploying the invention was seen as less of an impediment to progress than having most inventions not be deployed, or even made, at all.
The idea was to set the time limit to maximize progress to the benefit of all/the country, and make manufacturing and technology grow like yeast (ala silicon valley B-) ). Part of the intent was to bias it toward innovators and make established processes free to use, because when the country was getting started the established players were owned by foreign interests. The founders wanted the country to develop its own industry, rather than being dependent on, and sending most of the profit to, big businesses in Europe.
But the time was set for heavy manufacturing at the pace of the period. It's a horrible mismatch for, say, software: With the availability of general purpose computing platforms, able to make distributable copies at electronic speed and copyright to prevent verbatim cloning, a person or company with a new software product can go from steath-mode program development to market establishment, profitibility, and even market dominance in a matter of months, before competitors can engineer their own version. So patents aren't necessary to promote innovation, leaving just their retarding effect holding down the blaze of creativity. (Then there's open source, with its alternitive monitization and/or reward strategies. But that's a "new invention". B-) )
It seems to me that:
- The expiration of patents on stereolithography did help produce the initial explosion of new, and often inexpensive, devices and the improvements in what can be made, how accurately, and how inespensively.
- The availability of machines suitable for practical industrial prototyping - even before the cheap machine explosion - pretty much forced the high-end CAD software producers to include some form of stereolithography output format, while an open output format made the choice obvious. That's a big benefit to the toolmaker for a small effort. The availability in the high-grade commercial tools is a great synergy and helps a lot. But the hobby machines needed CAD tools and open source was already up to the task: Had the big players not gone along it still would have been done, and those big players not "with the program" would be experiencing major competitive pressure from open source tools and competitors that did provide such output.
And here's the key:
- The availabitiy of these rapid general-purpose maufacturing tools will bring (is already bringing!) software's high-speed innovation and entrepenurial models to the manufacture of physical objects. Patents could be shortened in term or reduced to "design patents" - the manufacturing equivalent of copyright - and produce a physical-product explosion comparable to the computer revolution. (Or patents, like "content" copyright, could become the tool of obsoleted established players in the suppression of the competing business models.)
Brace yourself for either the physical-manufacture ramp-up to science-fiction's "singularity" or an ongoing RIAA / MPAA / conglomerate - style legal battle.
So it's telling us just what we already knew? Interesting.
For three or more decades. (Before that some of the classes of things they're comparing didn't exist, with enough deployment, to characterize.)
On the other hand, it's nice to have it confirmed with some rigor and measures.
Oops. Typoed $/watt to $/kW in part of the above and accidentally hit submit rather than preview. My bad.
A dollar capital cost per kW of generation (with a couple decades lifetime minimum) is the ballpark for the breakeven point between grid power and solar generation on mid-US-latitude sunny sites (5ish solar hours/day), with grid power available.
Being remote (so running grid is pricey) or having a small load (so basic connection fees aren't justified) shifts the point to higher dollars/watt, as does an increase in utility rates. Shade, dark weater, and high lattitude shifts it downward. (Forget about solar in Seattle, for instance.)
Solar panels are just starting to drop below $1/W, making them practical in far more places, and making the load size and associated system costs (mounting, inverters, storage) more of a factor.
Over $/W? It needs some exceptional situation to compete with cheap flat panels.
The headline says farmers. The text says farm workers. Very much not the same thing. A farmer is the owner of the farm. A farm worker is generally a hired hand, often (though not always) a migrant, and if so typically from Mexico or farther south.
The story suggests that the multi-drug-resistant bacteria are the result of antibiotic treatment of the animals at the farm. This misses another possibility:
In Mexico, most antibiotics are over-the-counter, much like asprin here in the US. People who feel ill or have some infection often buy and take them. Typically they use them until they no longer show symptoms - then stop, rather than taking a full regimin and killing off all the bacteria. (Why take more of the non-free drug once the symptoms are gone? Waste of money, right?) This is a recipe for creating drug-resistant bacteria.
Of course if an infection is resistant to one antibiotic, a paitent is likely to try another, and another, and so on until they find one that works. THAT's a recipe for maintaining and improving the bug's resistance to the front line antibiotics while breeding resistance to others.
As a result, a substantial fraction of the workers arriving from south of the Mexican border are carriers of multi-drug-resistant baceria.
Meanwhile, a farming operation is likely to give a limited number of antibiotics continuously, so non-resistant infections are wiped out before they can develop resistance, and if they do develop resistance it will be to the particular drugs used, rather than the universe of antibiotics.
Of course, infected workers can infect livestock, just as livestock can infect workers. And infected workers can trade infections around, just as livestock can. (More so, since the livestock tends to be kept separated, to reduce both disease spread and breeding by unintended pairings, limitations that farmers can't impose on their workers - and would be unlikely to try even if they could.)
So it seems to me that responsible researchers would go a bit farther before reporting: Like by doing genetic testing on the strains of bug in the various workers and the livestock, and running models on the results to try to identfy whether the bugs are from the herd or the workers.
I don't see any such work alluded to in this popularized reporting. It seems to just assume that the bugs were developed on the farm and spread to the workers. I hope this is a disconnect between the actual research and the report, rather than an accurate characterization of the research.
It would have been surprising if the US would have implemented treaties differently from every other country.
Why?
It does a LOT of things differently from other countries. It redefined "republic", just for starters.
The gas bag itself was flammable; it wouldn't have mattered what gas was in it, when it disintegrated
In particular: The paint. It contained a mix of powdered aluminum and iron oxide pigments, in sufficient concentration to maintain a redox reaction.
You and I know this mixture as "thermite". It's really hard to get the reaction started - but an electric discharge can do it. (They tried to tether it with an electrical storm approaching. That would make one hell of a spark when the charged envelope comes near to connecting to the grounded mast - which is about when the fire started.) Once it's started, the reaction is essentially impossible to extinguish. The aluminum steals the oxygen from the iron oxide. The heats of formation of the two oxides differ so much that the energy released leaves the resulting elemental iron as an orange-glowing liquid and the aluminum oxide incandescent white-hot.
You are bound by the treaties your country signed.
Yes: You, and the states, and their courts, are bound by them (to the extent they are clear or were implemented by federal enabling legislation).
In fact, they have more legal weight in the US than laws passed by your own Congress.
NO! They have EXACTLY the same weight as federal law. Both treaties and federal law are trumped by the Constitution, and both are also creatures of Congress, They can be modulated, and destroyed (at least in how they are effective within the country) by congressional action.
The idea that they're any stronger or more permanent than federal legislation comes from a (very common) misreading of the Supremacy Clause:
This says that the Constitution, Federal Law, and Treaties trump state law in state and federal courts. It says nothing about the relative power among the three.
The misreading is to interpret "all treaties made ... shall be the supreme law of the land ..." to mean that treaties effectively amend the constitution. This is wrong. You can see it by noticing the same kind of misreading also makes federal law equivalent to a constitutional amendment - which it clearly is not.
In fact the Supreme Court has spoken on the relation between the Constitution and treaties: In Reid v. Covert, 354 U.S. 1 (1957), the Supreme Court held stated that the U.S. Constitution supersedes international treaties ratified by the U.S. Senate.
Treaties are abrogated, at the federal level, all the time, and there are a number of mechanisms for doing so.
Now they have the guide printed on the box but I can remember when i was a kid they didn't.
Some off them had maps at least as far back as the '50s, and probably much further.
A classic was the "Whitman Sampler" - an assortment of their products with a handy map. In addition to being a tasty and relatively low-priced collection of their products, it let a family divide them up according to their individual preferences, and gave you the names of each, so you could (at least hypotheically) buy boxes of just the ones you like.
(I say hypothetically because I never saw boxes of the individual candies being carried in the stores that sold the samplers.)
But regardless of the pressure, when the helium leaks out, it will not be displaced by air. It will leave behind a vacuum. The helium will leak out, but nothing will leak in to replace it.
(Except maybe hydrogen, but there's not much of that in your local air.)
So your metal parts vacuum-weld and tear themselves apart starting at the contacting surfaces, and adding lots of hydrogen to the air around the drives just makes the parts become brittle on their way to failure.
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.
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.)
Do dinosaurs taste like chicken?
They ought to. Recent research has shown that chickens are the closest living relative of T. Rex.
... 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.)
A couple thousand small claims cases a month might be more effective than a class action suit for getting their act cleaned up.
Did I just invent an open source / populist / minarchist alternative to the class action lawsuit? B-)
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.
