Teacher NZ’s first victim of superbug

Tuesday, November 19th, 2013

– This story is a first for New Zealand but it will not be the last.  

– All around the world, antibiotic resistance, among virulent strains of bacteria, is rising as a result of the indiscriminate and careless application of antibiotics.

– The problem is that people are prescribed a course of antibiotics but they only take part of them.  They decide, all on their own and against medical advice, that they feel fine and don’t need to finish the entire course.

– But what happens, when you are taking a course of antibiotics, is that the weakest of the bugs succumb first to the drugs and it takes until near the end of the course before the strongest and most resistant of the bugs succumbs.

– So, if you stop early, you’ve only killed the weakest ones and the strongest one survive and carry on.  

– When such bugs pass through person after person, each of whom doesn’t complete the course, the net effect is like a filter that acts to concentrate and strengthen and nastiest of the bugs.  

– And, eventually, the bugs strength and resistance is such that antibiotics will no longer touch them.

– People have misused antibiotics in this way since they were invented.  

– For a long time, the answer to increasing resistance was to invent or discover a new antibiotics to deal with the bugs that had become resistant to other antibiotics.

– But, it has become more and more difficult to invent or discover new antibiotics even as the abuse of the existing antibiotics continues.

– So, the net effect world-wide is that the bugs are getting stronger and the antibiotics less effective and there will be a time, soon, when we will return to the bad-old-days; the way they were before we had antibiotics.

– So, unless we discover some new antibiotics, those bad-old-days, which are soon to come again, will be upon us.  And simply being near someone with, say, tuberculosis could be a death sentence.

– Think about this the next time someone coughs near you in public.

– There are several morals to this story, if such things appeal to you:

– (1) No single rain drop thinks it is responsible for the flood.

– (2) Electing politicians who don’t ‘believe’ in science is a sure guarantee of future pandemics.

– (3) Thinking about where you live in terms of population density, the quality of your medical care and the level of intelligence among your politicians – these things are in your best interest.

– (4) If you think this is not happening around you, you’ve been ignoring science and the warnings it has been issuing for a long time now.

– And remember, nature doesn’t care what you ‘believe’.   And nature bats last.

He died fighting a superbug that no antibiotic in the world could touch.

Wellington teacher Brian Pool is believed to be New Zealand’s first victim of an aggressive superbug, caught while he was overseas, that is resistant to every type of antibiotic.

Pool, 68, spent most of the last six months of his life in quarantine, unable to leave his room even to sit in the courtyard.

“It was sad because we couldn’t give him a hug, we couldn’t really kiss him,” twin sister Maureen Dunn said.

“He just wanted to get out in the sun, and we couldn’t take him out.

“Being his twin sister, I would be the one who always rescued him . . . it was terrible, but there was nothing we could do.”

Her brother died on July 6, from complications caused by a stroke and unrelated to the bug.

But doctors say his immune system was weakened by fighting the nightmare bacteria.

The adventurous teacher, known for his quirky sense of humour, was living in Vietnam and teaching English when he suffered a brain haemorrhage on January 6.

He had surgery in Vietnam, where part of his skull was removed to relieve pressure on his brain, and was flown to New Zealand.

In Wellington Hospital, he was immediately isolated, a standard precaution for overseas patients.

Tests revealed he was carrying a strain of bacterium known as KPC-Oxa 48 – a “pan-resistant” organism that repels every kind of antibiotic.

“Nothing would touch it. Absolutely nothing,” Wellington Hospital clinical microbiologist Mark Jones said yesterday.

“It’s the first one that we’ve ever seen that is resistant to every single antibiotic known.

“This man was in the post-antibiotic era, and this is why so many agencies over the world are raising alarm bells.”

Earlier this year, British chief medical officer Sally Davies described resistance to antibiotics as a “catastrophic global threat” that should be ranked alongside terrorism.

New Zealand hospitals are already seeing increasing cases of multi-resistant “superbugs”, which can be treated by only a limited number of expensive antibiotics.

Dunn said the family was frightened, and even Mr Pool’s doctors did not seem to know what the superbug might do.

“They were shit scared, to put it bluntly, in case these bugs were transferred to another patient or taken out into the community.”

‘Uncomfortable’ climates to devastate cities within a decade, study says

Monday, November 4th, 2013

– This is what John Roach of NBC News has to say on October 9th, 2013

– But this has all been coming, writ large, for a long time.  

-It’s been coming since:

Lyndon Johnson discussed the CO2 we were putting into the atmosphere in 1965.

Since the Club of Rome discussions and their paper on “The Limits to Growth” in 1972.

Since the World Scientists issued their warning to Humanity in 1992.

– But it is only just now beginning to reach the evening news as plausible news.  

– We have just a few greedy, self-centered people and corporations to thank for the fact that their misinformation has been instrumental in delaying humanities waking up on these threats until it is virtually too late.  

Most recently, Naomi Oreskes showed us this in her book, Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming

– Some of us remember how Mussolini ended up.   I wonder, when the damages are finally appreciated, if these folks may fare the same.   I won’t cry any crocodile tears for them; that’s for sure.  

-By their actions many, many millions will die, cities and nations will fall, species innumerable will go extinct and most of our descendants will have less than optimal lives to look forward to; if they manage to live through the changes that are coming.

Lesser daysThe world is hurtling toward a stark future where the web of life unravels, human cultures are uprooted, and millions of species go extinct, according to a new study. This doomsday scenario isn’t far off, either: It may start within a decade in parts of Indonesia, and begin playing out over most of the world — including cities across the United States — by mid-century.

What’s more, even a serious effort to stabilize spiraling greenhouse gas emissions will only stave off these changes until around 2069, notes the study from the University of Hawaii, Manoa, published online Wednesday in the journal Nature. The authors warn that the time is now to prepare for a world where even the coldest of years will be warmer than the hottest years of the past century and a half.

“We are used to the climate that we live in. With this climate change, what is going to happen is we’re going to be moving outside this comfort zone,” biologist Camilo Mora, the study’s lead author, told NBC News. “It is going to be uncomfortable for us as humans and it will be very uncomfortable for species as well.”

Naomi Klein: How science is telling us all to revolt

Tuesday, October 29th, 2013

– I don’t think the best of our idealists are going to be going out on Greenpeace ships any more to protest politely.   Not when they stand to lose the most of their young lives sitting in Russian prisons for the crime of idealism and the crime of trying to wake people up to the stupidity and danger gathering all around us.

– The days or holding signs and protesting peacefully are withering away all over the world as people realize that none of that has been effective.   And now it is become downright dangerous.

– I first read that an ecologically sane world and the world of Capitalism may not be compatible bedfellows on this planet back in 2008 when I read The Bridge at the Edge of the World by James Gustave Speth; Yale University.   He is and has been a major leading light in all things environment in the U.S. and he’s been a team player all along.  So, this was a hard conclusion for him to come to.

– In the article, below, Naomi Klein tells us that others up and down the line are coming to the same conclusions.  

– If what we’ve been doing isn’t working and losing is not an option for those of us who love this world and our children, then quite simply, new measures will be needed.

Is our relentless quest for economic growth killing the planet? Climate scientists have seen the data – and they are coming to some incendiary conclusions.

In December 2012, a pink-haired complex systems researcher named Brad Werner made his way through the throng of 24,000 earth and space scientists at the Fall Meeting of the American Geophysical Union, held annually in San Francisco. This year’s conference had some big-name participants, from Ed Stone of Nasa’s Voyager project, explaining a new milestone on the path to interstellar space, to the film-maker James Cameron, discussing his adventures in deep-sea submersibles.

But it was Werner’s own session that was attracting much of the buzz. It was titled “Is Earth F**ked?” (full title: “Is Earth F**ked? Dynamical Futility of Global Environmental Management and Possibilities for Sustainability via Direct Action Activism”).

Standing at the front of the conference room, the geophysicist from the University of California, San Diego walked the crowd through the advanced computer model he was using to answer that question. He talked about system boundaries, perturbations, dissipation, attractors, bifurcations and a whole bunch of other stuff largely incomprehensible to those of us uninitiated in complex systems theory. But the bottom line was clear enough: global capitalism has made the depletion of resources so rapid, convenient and barrier-free that “earth-human systems” are becoming dangerously unstable in response. When pressed by a journalist for a clear answer on the “are we f**ked” question, Werner set the jargon aside and replied, “More or less.”

There was one dynamic in the model, however, that offered some hope. Werner termed it “resistance” – movements of “people or groups of people” who “adopt a certain set of dynamics that does not fit within the capitalist culture”. According to the abstract for his presentation, this includes “environmental direct action, resistance taken from outside the dominant culture, as in protests, blockades and sabotage by indigenous peoples, workers, anarchists and other activist groups”.

Serious scientific gatherings don’t usually feature calls for mass political resistance, much less direct action and sabotage. But then again, Werner wasn’t exactly calling for those things. He was merely observing that mass uprisings of people – along the lines of the abolition movement, the civil rights movement or Occupy Wall Street – represent the likeliest source of “friction” to slow down an economic machine that is careening out of control. We know that past social movements have “had tremendous influence on . . . how the dominant culture evolved”, he pointed out. So it stands to reason that, “if we’re thinking about the future of the earth, and the future of our coupling to the environment, we have to include resistance as part of that dynamics”. And that, Werner argued, is not a matter of opinion, but “really a geophysics problem”.

Plenty of scientists have been moved by their research findings to take action in the streets. Physicists, astronomers, medical doctors and biologists have been at the forefront of movements against nuclear weapons, nuclear power, war, chemical contamination and creationism. And in November 2012,Nature published a commentary by the financier and environmental philanthropist Jeremy Grantham urging scientists to join this tradition and “be arrested if necessary”, because climate change “is not only the crisis of your lives – it is also the crisis of our species’ existence”.

Privatize profit, socialize debt…

Thursday, October 24th, 2013

“Privatize profit, socialize debt… and risk… and pretty much everything else.  This is the current global system and the pattern is apparent everywhere.  If many sectors of the economy actually had to pay their way they would not be profitable at all.  The state of ecosystems around the world stands as testimony.”

The most depressing Discovery about the Brain, Ever

Wednesday, September 18th, 2013

“It turns out that in the public realm, a lack of information isn’t the real problem.  The hurdle is how our minds work, no matter how smart we think we are.  We want to believe we’re rational, but reason turns out to be the ex post facto way we rationalize what our emotions already want to believe.”

– Makes sense to me.  So many decisions I see being made in our world seem so inexplicable.   As Paul Simon wrote in his song, “The Boxer”:

“A man hears what he wants to hear and disregards the rest.”

Educating monkeys

Say goodnight to the dream that education, journalism, scientific evidence, or reason can provide the tools that people need in order to make good decisions.

Yale law school professor Dan Kahan’s new research paper is called “Motivated Numeracy and Enlightened Self-Government,” but for me a better title is the headline on science writer Chris Mooney’s  piece about it in Grist:  “Science Confirms: Politics Wrecks Your Ability to Do Math.”

Kahan conducted some ingenious experiments about the impact of political passion on people’s ability to think clearly.  His conclusion, in Mooney’s words: partisanship “can even undermine our very basic reasoning skills…. [People] who are otherwise very good at math may totally flunk a problem that they would otherwise probably be able to solve, simply because giving the right answer goes against their political beliefs.”

In other words, say goodnight to the dream that education, journalism, scientific evidence, media literacy or reason can provide the tools and information that people need in order to make good decisions.  It turns out that in the public realm, a lack of information isn’t the real problem.  The hurdle is how our minds work, no matter how smart we think we are.  We want to believe we’re rational, but reason turns out to be the ex post facto way we rationalize what our emotions already want to believe.

For years my go-to source for downer studies of how our hard-wiring makes democracy hopeless has been  Brendan Nyhan, an assistant professor of government at Dartmouth.

Nyan and his collaborators have been running experiments trying to answer this terrifying question about American voters: Do facts matter?

The answer, basically,  is no.  When people are misinformed, giving them facts to correct those errors only makes them cling to their beliefs more tenaciously.

A Jewel at the Heart of Quantum Physics

Amplutihedron

– Highly interesting article making the rounds.   Could open up an entirely new Physics.   Space and time may no longer be prime-time players.

– dennis

= = = = = = = = = = = = = = = = = = = = = = = = =

Beyond making calculations easier or possibly leading the way to quantum gravity, the discovery of the amplituhedron could cause an even more profound shift, Arkani-Hamed said. That is, giving up space and time as fundamental constituents of nature and figuring out how the Big Bang and cosmological evolution of the universe arose out of pure geometry.

“In a sense, we would see that change arises from the structure of the object,” he said. “But it’s not from the object changing. The object is basically timeless.”

Human irrationality

Friday, August 30th, 2013

I’ve cited three things that are illustrative of humanities irrationality:

1. Near vs far

2. Now vs. future

3. Concrete vs abstract

Humans irrationally favor near, now and concrete over far, then and abstract and because of this bias, they make bad decisions.

Now, add a fourth: Personal vs. Them as in me and mine and they and theirs.

But, the deep truth that shows the irrationality of all of these biases is the simple fact that everything in this world is ‘one’.

Paris notes: 5 August 2013

Thursday, August 8th, 2013

I have to say that sometimes the news brings me down so badly.

I’ve been thinking about and advocating the idea that until humanity decides that its highest priority is to maximize the quality of life for all, we will inevitably fall victim to the default alternative which is that every individual’s highest priority is to look out for themselves.

And, by themselves, I mean both individual people and corporations.

Today, I read the August 5th copy of the International Herald Tribune and there was this:

In need of a new hip, but priced out of the U.S.” – A man went to Belgium and had his hip replaced for $13,600 USD. You’ll have to read the article to see how much it would have cost him in the U.S., and why.

I warn you, it’s going to be all about profits over the welfare of people.

And then this:

Nuclear scandal snowballs in S. Korea” – A story about how many of the tests and inspections that were intended to ensure the safety of S. Korean nuclear plants has been discovered to have been faked by the testing companies and the nuclear plant designers.

I warn you, it’s going to be all about profits over the welfare of people.

And then this:

As cost of importing food soars, Jamaica turns to the earth” – a little story about how the Jamaican government is now strongly advising people to begin to grow their own food.

I wonder if any of you saw the documentary entitled, ‘Life and Debt’ 10 or 15 years ago? It was about Jamaica, Mon.

It was about the arrival of “Globalization’ and how the low price of imported grain had driven most of the small farmers off their land and into the cities since they could not complete with the price of the grain being dumped into their market.

But, at the time it was explained, ‘Globalization’ was all for the good of all of us long-term.

Now that the Jamaicans don’t grow much food, it’s the time to hike the prices and squeeze them. And so the circle turns.

I warn you, it’s going to be all about profits over the welfare of people.

And that was just one issue of the paper on an apparently normal day.

And then when I tell people that the corporations, looking out for their own best interests, are steadily taking over governments and their regulatory processes – and I see that they think I’m peddling conspiracy theories to them, I’m stunned.

It’s as if I’m watching a line of cows entering the slaughter house and I’m warning them about where they’re going and they all laugh; sure that they are off to a Caribbean vacation.

I haven’t posted much here for awhile since I’ve been traveling.  But, not much need.   Nothing’s changed.

Time on your hands?

Wednesday, May 1st, 2013

 

Woo-Woo

– Time is an interesting something.   Or, maybe not.  

– A recent issue of Scientific American, that focused the entire issue on the subject of Time, revealed that about 50% of the scientists who study time believe that time exists while the other 50% think it is an artificial construct that comforts our minds but that actually doesn’t exist.

– So here, for those of you who like to leaven your doom and gloom with a bit of science, are three articles that delve into the endlessly fascinating subject of something we’re not even sure if it exists.   Nice, eh?

No Rich Child Left Behind

Wednesday, May 1st, 2013

– An excellent article.  I get discouraged at times by this world but there are still good people doing good work to try to improve our self-understanding and thus, the possibility that we can avoid shooting ourselves in the foot.

Here’s a fact that may not surprise you: the children of the rich perform better in school, on average, than children from middle-class or poor families. Students growing up in richer families have better grades and higher standardized test scores, on average, than poorer students; they also have higher rates of participation in extracurricular activities and school leadership positions, higher graduation rates and higher rates of college enrollment and completion.

Whether you think it deeply unjust, lamentable but inevitable, or obvious and unproblematic, this is hardly news. It is true in most societies and has been true in the United States for at least as long as we have thought to ask the question and had sufficient data to verify the answer.

What is news is that in the United States over the last few decades these differences in educational success between high- and lower-income students have grown substantially.
