298 Baptistina

The more important discovery of a particular asteroid hitting earth, and wiping out the dinosaurs, which is how the MSM covered it, is the final two paragraph's.

IT WAS once suggested, to illustrate the chaotic and unpredictable way in which natural systems behave, that the beat of a butterfly's wing in China could eventually trigger a hurricane in the Atlantic. A bit of an exaggeration, perhaps, but the point was that even in the theoretically deterministic world of Newtonian mechanics, only a small amount of complexity is needed to make practical prediction well nigh impossible.

Thus it is perhaps not as far-fetched as it sounds to suggest that the collision 160m years ago of two space rocks, albeit quite large ones, resulted in the stormy death almost 100m years later of the dinosaurs and many other species on Earth. For although the orbits of the planets look to astronomers like a model of regular, Newtonian clockwork, on a scale of millions of years, the solar system is every bit as chaotic as the Earth's weather.

Asteroid that wiped out dinosaurs traced

Around 65 million years ago, one 10-kilometre-wide piece crunched into Earth, unleashing a firestorm and kicking up clouds of dust that filtered out sunlight. In this enduring winter, much vegetation was wiped out and the species that depended on them also became extinct. Only those animals that could cope with the new challenge.

The trace of the great event, called the Cretaceous/Tertiary (or K-T) extinction event, can be seen today in the shape of a 180-kilometre-diameter impact crater at modern-day Chicxulub, in Mexico's Yucatan peninsula.

The trio of researchers – William Bottke and David Nesvorny of Southwest Research Institute in Colorado, U.S. and David Vokrouhlicky of the Czech Republic's Charles University in Prague – took their theory a stage further and checked out sediment samples from the Chicxulub site. They found traces of a mineral called carbonaceous chondrite, which is only found in a tiny minority of meteorites, as the Earthly remains of plummeting asteroids are called. Most asteroids can be excluded from the Chicxulub event, but not Baptistina-era ones, they contend.

Putting simulation and chemical evidence together, the team rule out theories that a comet was to blame rather than an asteroid, and say there is a "more than 90 per cent" probability that the killer rock was a refugee from the Baptistina family.

The investigators also argue that there's a 70 per cent chance that a four-kilometre-wide Baptistina asteroid hit the Moon some around 108 million years ago, forming the 85-kilometre crater Tycho.

An important point raised by the study "is how severe the repercussions of cataclysmic collisions in the asteroid belt can be for the Earth–Moon system," commented geologists Philippe Claeys and Steven Goderis of Vrije University in Brussels, Belgium, in an accompanying commentary also in Nature.

"The terrestrial impact record needs to be scrutinized more closely to identify and understand these periods of more intense bombardment, and to link them to the huge and dangerous game of billiards continuously being played out between the orbits of Mars and Jupiter,"
they said.

Brave New World


When I went to high school utopian and dystopian novels were considered must reading in social studies class. And this reminded me of Aldous Huxely's brilliant, and underappreciated, dystopian society of Brave New World.

Who is human? Do Chimeras have souls?

The English have decided that they will allow their scientists to combine human genes with animal genes to make embryos.

The embryos will not be a few human genes in an animal embryo, or a few animal genes in a human embryo, but a full blown merger of animal eggs and bird eggs to form a “chimera”, a mixed animal human being.


While the author, who opposes this on moral grounds, refers to H.G. Wells, Island of Dr. Moreau, and the more obscure Cordwainer Smith! Whom I also read while attending high school. Checking on his bio, I discover another influence on my theory of conspiratology.

Which seems appropriate given the conspiracies and conspiracy theories abounding around Chimera's.

Scientists have begun blurring the line between human and animal by producing chimeras—a hybrid creature that's part human, part animal.

Writers ranging from ancient Greek and Hindu poets to novelist Michael Crichton have all envisioned the fictional possibility of creating human-animal hybrids. The notion of "chimeras" was particularly horrifying to H. G. Wells, author of "The Island of Dr. Moreau."

But over the past two years, the subject has quietly made its way into scientific journals. Unbeknownst to most Americans, today the creation of human-animal chimeras represents a valuable experimental tool that could revolutionize science and medicine.

However, the creation of these hybrid organisms also raises ethical questions: What rights should these organisms possess?

Great Britain has already begun to take up the question; an official government report released last month backed the creation of human-animal hybrid embryos).

One of the main forces driving research in this area is the widespread interest in human embryonic stem cells. In vitro experiments suggest that these cells can differentiate into any cell type in the body, but whether they would retain that potential if implanted in an actual human body is not yet clear.

Chimera embryos have right to life, say bishops

A recent article (subscription required) in the NY Times Science section discusses the role of interspecies chimeras in biomedical research. They point out the chimeric organisms are nothing new:

“Biologists have been generating chimeras for years, though until now of a generally bland variety. If you mix the embryonic cells of a black mouse and a white mouse, you get a patchwork mouse, in which the cells from the two donors contribute to the coat and to tissues throughout the body. Cells can also be added at a later stage to specific organs; people who carry pig heart valves are, at least technically, chimeric.”
Regardless of the minimal ethical controversy amongst biologists, new research using other animals (e.g., pigs) to harvest human organs derived from progenitor cells has the potential to "gross out" most Americans. In essence, it's analogous to watching a horror film with a mad scientist manipulating the natural order for some (often undefined) egomaniacal purpose.

The Stranger Within

New Scientist vol 180 issue 2421 - 15 November 2003, page 34

Human chimeras were once thought to be so rare as to be just a curiosity.
But there's a little bit of someone else in all of us, says Claire
Ainsworth, and sometimes much more...

EXPLAIN this. You are a doctor and one of your patients, a 52-year- old
woman, comes to see you, very upset. Tests have revealed something
unbelievable about two of her three grown-up sons. Although
she conceived them naturally with her husband, who is definitely
their father, the tests say she isn't their biological mother.
Somehow she has given birth to somebody else's children.

This isn't a trick question - it's a genuine case that Margot Kruskall, a
doctor at the Beth Israel Deaconess Medical Center in Boston,
Massachusetts, was faced with five years ago. The patient, who we will
call Jane, needed a kidney transplant, and so her family underwent blood
tests to see if any of them would make a suitable donor. When the results
came back, Jane was hoping for good news.

Instead she received a hammer blow. The letter told her outright that
two of her three sons could not be hers. What was going on?

It took Kruskall and her team two years to crack the riddle. In the end
they discovered that Jane is a chimera, a mixture of two individuals -
non-identical twin sisters - who fused in the womb and grew into a single
body. Some parts of her are derived from one twin, others from the other.
It seems bizarre that this can happen at all, but Jane's is not an
isolated case. Around 30 similar instances of chimerism have been
reported, and there are probably many more out there who will never
discover their unusual origins.

John Tory Sees Flying Spaghetti Monster

This is scary. Ontario Conservative Leader John Tory thinks that a creation myth is equivalent to the scientific theory of evolution.

The Conservatives have pledged to give private religious schools $400 million if they opt into the public system, teach the provincial curriculum, hire accredited teachers and administer tests, Tory said. The funding would not prohibit Christian schools from teaching creationism on top of the existing provincial curriculum, he added.

"It's still called the theory of evolution. They teach evolution in the Ontario curriculum, but they also could teach the fact to the children that there are other theories that people have out there that are part of some Christian beliefs."

He has confused empirical theory with metaphysics.

This is of course understandable since the word physics appears in the latter. Which has nothing to do with science but refers to the physical world.

Given John Tory's belief that creationism is equivalent to evolution I would hope his new curriculum would include the creation theory of the Church of the Flying Spaghetti Monster.

A Big But


When an explanation is not an explanation it usually ends with a "but".

As is in this case of the latest scientific explanation for why folks experience their astral body.


"Brain dysfunctions that interfere with interpreting sensory signals may be responsible for some clinical cases of out-of-body experiences," said Henrik Ehrsson, a neuroscientist formerly of University College London, and now at the Karolinska Institute in Sweden.

"Though, whether all out-of-body experiences arise from the same causes is still an open question," he added.

Holy Kryptonite Superman

It makes sense that a Canadian should discover Kryptonite, since it is Superman's nemesis and Superman was a Canadian invention.

And it further makes sense it should be discovered in Siberia, an allegorical frozen land just like where Superman hid his Fortress of Solitude.

And maybe the meteor from Krypton was the one that crashed into Tunguska, Siberia in 1908.

Siberian mineral spells trouble for Superman

Their findings confirmed Stanley's view that the mineral -- determined to be sodium lithium boron silicate hydroxide -- was new to science, and the team prepared a paper for the European Journal of Mineralogy to report the discovery. The researchers conducted standard searches in the scientific literature to make sure nothing had been previously published about such a mineral composition. Then Stanley -- whom Le Page describes as a particularly meticulous scientist "who likes to check everything" -- did a final Internet search using Google to make sure nothing had been missed.

"And guess what came out?" a chuckling Le Page told CanWest News Service on Tuesday.

Stanley found nothing to suggest other scientists had beaten his team to the punch. But the web search did produce a match with a Wikipedia site about kryptonite, the pretend stuff Superman's enemies -- particularly the diabolical Lex Luthor -- like to use against the world's original caped crusader.

Usually depicted in comics and films as a green, glass-like shard of rock, kryptonite can quickly turn Superman into a grimacing, helpless weakling.

"Towards the end of my research I searched the web using the mineral's chemical formula -- sodium lithium boron silicate hydroxide -- and was amazed to discover that same scientific name, written on a case of rock containing kryptonite stolen by Lex Luthor from a museum in the film Superman Returns," Stanley said in a statement released Tuesday by the Natural History Museum.

"The new mineral does not contain fluorine (which it does in the film) and is white rather than green but, in all other respects, the chemistry matches that for the rock containing kryptonite."

Groupthink

We sometimes overlook the most obvious connection between deniers, those who deny global warming, those who deny evolution and those who deny the holocaust.

They suffer from the same kind of
groupthink and conspiracy theories.

Its not denial they say, it's debate they want, the facts are not irrefutable, there is evidence to the contrary.

For a long time Bradley Smith has tried to present himself as an honest chap, a champion of intellectual freedom simply seeking an "open debate"about the "holocaust controversy [sic]." But this debate is a sham. The so-called holocaust controversy does not exist. It is the invention of a collection of long-time anti-Semites and apologists for Hitler.

On the surface
, Holocaust deniers portray themselves as individuals and groups engaged in a legitimate, dispassionate quest for historical knowledge and "truth."

Dressing themselves in pseudo-academic garb, they have adopted the term "revisionism" in order to mask and legitimate their enterprise. After all, the ongoing challenge to and revision of previously accepted historical interpretation is one of the hallmarks of the professional historian's craft.


Of course most holocaust deniers are right wing kooks that even other right wingers disavow or do they? Not so. Once upon a time they had powerful business backers, and in many cases still do today.

Like Robert Welch Jr. who founded the John Birch Society. Today the Birchites focus their criticism on immigration, legal or illegal and the UN. There are many in a variety of right wing movements, like the Minutemen, whose roots go back to the sixties and the World Anti-Bolshevik Movement which gave succour to post WWII fascists.

The right wing is inundated with conspiracy theorists, holocaust deniers and neo-fascists. And ideological differences aside they are part of the 'mainstream' right, they are backed by private business interests and the tactics they have developed over fifty years of lobbying in the United States remain the same.

Because they are effective. Deny that your opponents have evidence, claim something is a theory, not a fact and viola, their views are challenged for there creditability.

Thus the same argumentative tactic used to deny the holocaust is used to deny evolution and used to deny climate change. It is groupthink on the right. And the argumentative style does not change, the subject of the attack does.

And it is always tinged with conspiracy theory, that the scientific or historical facts are being foisted on us because it is consensus reality, consensus of those in power it is not the 'real thing'.

So all the historians that accept the holocaust are establishment historians not 'real' historians. Scientists that accept evolution or global warming are not 'real' scientists.


The only place that a climate change science consensus exists is in what Essex and McKitrick call 'Official Science', the collective voice of governments and other so-called 'science authorities'. But this is not real science.


The Climate Change Deniers have money and powerful connections they have used to discredit their opponents, in this case other scientists and academics. And sometimes do so to end careers, literally terrifying their opponents into silence. Certainly a form of fascism.


"There is a strategy to single out individuals, tarnish them and try to bring the whole of the science into disrepute," he says. "And Kevin [Trenberth] is a likely target." Mann agrees that the scientists behind the upcoming IPCC report are in for a rough ride. "There is already an orchestrated campaign against the IPCC by climate change contrarians," he says.

Many of the IPCC's authors, some of whom asked not to be named, say this is a smokescreen. They claim there is an extensive network of lobby groups and scientists involved in making the case against the IPCC and its reports. Automobile, coal and oil companies have coordinated and funded past attacks on them, the scientists say. Sometimes this has been done through Washington lobby groups such as the Competitive Enterprise Institute (CEI), whose officers include Myron Ebell, a former climate negotiator for George W. Bush's administration. Recently, the CEI made television advertisements arguing against climate change, one of which ended with the words: "Carbon dioxide, they call it pollution, we call it life." CEI's past funders include ExxonMobil, General Motors and the Ford Motor Company.

The money trail

Some sceptical scientists are funded directly by industry. In July, The Washington Post published a leaked letter from the Intermountain Rural Electric Association (IREA), an energy company based in Colorado, that exhorted power companies to support the work of the prominent sceptic Pat Michaels of the University of Virginia, Charlottesville. Worried about the potential cost of cleaning up coal-fired power plants to reduce their CO2 emissions, IREA's general manager, Stanley Lewandowski, wrote: "We believe that it is necessary to support the scientific community that is willing to stand up against the alarmists... In February this year, IREA alone contributed $100,000 to Dr Michaels."


The Fraser Institutes response to the IPCC report was a long time in the making, and a coordinated effort between them and the anti-climate change lobby, the flat earthers, in the U.S., UK, Canada, Australia, New Zealand and Europe. And the organizations, front groups really, are all interconnected.

It was planned years ago, as new front organizations sprung up over the past three years in preparation for the IPCC report. While the Fraser Institute like its American counter-part the Cato Institute have existed since the seventies, groups like Canada's
Natural Resources Stewardship Project, and the New Zealand Climate Science Coalition are all relatively new lobbying groups. Even the older Friends of Science. was only created in 2002.

The push was on by the right and their big business backers when they saw the writing on the wall after Kyoto was signed. One faction of capitalism endorsed Kyoto, another was ambivalent, and a handful, but a powerful handful, vehmently opposed Kyoto.

Having lost the war they now engage in a protracted series of battles to attempt to inundate doubt in the public mind, using fronts like Junk Science.com and Fox News, various assorted right wing media mouthpieces in Canada, Europe and America. They know they have lost, but if in anyway they can hold back radical changes required to deal with the heat death of the planet, to save their industries they will. Victory to them is to delay change.

And they will never go away, another issue will come to the fore that they can delay, attack, undermine, and deny. And the consipiratorial politics of denial will once again be used.

The Right Wing exposes the Janus nature of the ruling class. One face appeals to the public as liberal, seeking to ameliorate the worst excesses of capitalism, the other jingoist, nativist, reactionary seeks to dominate through demagoguery and populism. One is enlightened capitalism the other is fascism. Both are false choices.

The alternative is, as it has always been for the past one hundred years, Barbarism or Socialism.

God Created Global Warming


Yep when you break down the arguments from the right that's what it comes down to.

Global Warming, like AIDS, is all part of Gods plan.


Global warming is a given. The cause of global warming is questioned. Some scientists blame man, just as many other scientists contend we are undergoing one of Earth's natural warming cycles.

Our planet has been cooling and warming since God created it.

Polyandry And Butterflies


This is a male fantasy, one male for forty females.....but wait it's butterflies we are talking about.

The fact that female butterflies could even find mates in the presence of male-killing Wolbachia stunned scientists. In some islands there was only one male for every 40 females. One would expect this type of sex imbalance to leave females deprived of a mate, explains Hurst.“To our knowledge we’ve never heard of female promiscuity being caused by fewer males,” he says.

What were they supposed to do remain childless spinsters? That ain't natural.

Another example of the birds and the bees, well butterflies anyways, and polyandry
