Independent:
Scientists have discovered a dramatic variation in the genetic make-up of humans that could lead to a fundamental reappraisal of what causes incurable diseases and could provide a greater understanding of mankind.
The discovery has astonished scientists studying the human genome – the genetic recipe of man. Until now it was believed the variation between people was due largely to differences in the sequences of the individual ” letters” of the genome.
It now appears much of the variation is explained instead by people having multiple copies of some key genes that make up the human genome.
Until now it was assumed that the human genome, or “book of life”, is largely the same for everyone, save for a few spelling differences in some of the words. Instead, the findings suggest that the book contains entire sentences, paragraphs or even whole pages that are repeated any number of times.
The findings mean that instead of humanity being 99.9 per cent identical, as previously believed, we are at least 10 times more different between one another than once thought – which could explain why some people are prone to serious diseases.
The studies published today have found that instead of having just two copies of each gene – one from each parent – people can carry many copies, but just how many can vary between one person and the next.
The studies suggest variations in the number of copies of genes is normal and healthy. But the scientists also believe many diseases may be triggered by an abnormal loss or gain in the copies of some key genes.
Another implication of the finding is that we are more different to our closest living relative, the chimpanzee, than previously assumed from earlier studies. Instead of being 99 per cent similar, we are more likely to be about 96 per cent similar.

Costas Efthimiou, a physics professor at the University of Central Florida, has done the math.
Legend has it that vampires feed on human blood and once bitten a person turns into a vampire and starts feasting on the blood of others.
Efthimiou’s debunking logic: On Jan 1, 1600, the human population was 536,870,911. If the first vampire came into existence that day and bit one person a month, there would have been two vampires by Feb. 1, 1600. A month later there would have been four, and so on. In just two-and-a-half years the original human population would all have become vampires with nobody left to feed on.
If mortality rates were taken into consideration, the population would disappear much faster. Even an unrealistically high reproduction rate couldn’t counteract this effect.
“In the long run, humans cannot survive under these conditions, even if our population were doubling each month,” Efthimiou said.

UPI 10/20:
A University of Washington economic geologist says there is lots of crude oil left for human use.
Eric Cheney (Y ’56, Y Ph.D. ’64) said Friday in a news release that changing economics, technological advances and efforts such as recycling and substitution make the world’s mineral resources virtually infinite.
For instance, oil deposits unreachable 40 years ago can be tapped using improved technology, and oil once too costly to extract from tar sands, organic matter or coal is now worth manufacturing. Though some resources might be costlier now, they still are needed.
“The most common question I get is, ‘When are we going to run out of oil?’ The correct response is, ‘Never,'” said Cheney. “It might be a heck of a lot more expensive than it is now, but there will always be some oil available at a price, perhaps $10 to $100 a gallon.”
Cheney also said that gasoline prices today, adjusted for inflation, are about what they were in the early part of the last century. Current prices seem inordinately high, he said, because crude oil was at an extremely low price, $10 a barrel, eight years ago and now fetches around $58 a barrel.

Alfred Tennyson opined that simple faith (was more) than Norman blood, and Tennyson may well be right.
Stephen Oppenheimer, one of the most prominent British autorities on DNA research, is contending that there simply isn’t all that much Norman blood around in Britain anyway, nor Celtic, nor Roman, nor Anglo-Saxon.
According to Oppenheimer,
Everything you know about British and Irish ancestry is wrong. Our ancestors were Basques, not Celts. The Celts were not wiped out by the Anglo-Saxons, in fact neither had much impact on the genetic stock of these islands…
The genetic evidence shows that three quarters of our ancestors came to this corner of Europe as hunter-gatherers, between 15,000 and 7,500 years ago, after the melting of the ice caps but before the land broke away from the mainland and divided into islands. Our subsequent separation from Europe has preserved a genetic time capsule of southwestern Europe during the ice age, which we share most closely with the former ice-age refuge in the Basque country. The first settlers were unlikely to have spoken a Celtic language but possibly a tongue related to the unique Basque language.
Another wave of immigration arrived during the Neolithic period, when farming developed about 6,500 years ago. But the English still derive most of their current gene pool from the same early Basque source as the Irish, Welsh and Scots. These figures are at odds with the modern perceptions of Celtic and Anglo-Saxon ethnicity based on more recent invasions. There were many later invasions, as well as less violent immigrations, and each left a genetic signal, but no individual event contributed much more than 5 per cent to our modern genetic mix…
based on the overall genetic perspective of the British, it seems that Celts, Belgians, Angles, Jutes, Saxons, Vikings and Normans were all immigrant minorities compared with the Basque pioneers, who first ventured into the empty, chilly lands so recently vacated by the great ice sheets.
By “Basque pioneers,” Oppenheimer is referring to female-line mitochondrial DNA haplogroup H1.
mtDNA Haplogroups in general.
Oppenheimer has a new book on all of this, titled The Origins of the British: A Genetic Detective Story.

Senator James M. Inhofe (R-OK) delivered a remarkable speech on Monday on the subject of the popular Global Warming delusion.
As the senator who has spent more time speaking about the facts regarding global warming, I want to address some of the recent media coverage of global warming and Hollywood’s involvement in the issue. And of course I will also discuss former Vice President Al Gore’s movie “An Inconvenient Truth.”
Since 1895, the media has alternated between global cooling and warming scares during four separate and sometimes overlapping time periods. From 1895 until the 1930’s the media peddled a coming ice age.
From the late 1920’s until the 1960’s they warned of global warming. From the 1950’s until the 1970’s they warned us again of a coming ice age. This makes modern global warming the fourth estate’s fourth attempt to promote opposing climate change fears during the last 100 years.
Recently, advocates of alarmism have grown increasingly desperate to try to convince the public that global warming is the greatest moral issue of our generation. Just last week, the vice president of London’s Royal Society sent a chilling letter to the media encouraging them to stifle the voices of scientists skeptical of climate alarmism.
During the past year, the American people have been served up an unprecedented parade of environmental alarmism by the media and entertainment industry, which link every possible weather event to global warming. The year 2006 saw many major organs of the media dismiss any pretense of balance and objectivity on climate change coverage and instead crossed squarely into global warming advocacy….
The media have missed the big pieces of the puzzle when it comes to the Earth’s temperatures and mankind’s carbon dioxide (C02) emissions. It is very simplistic to feign horror and say the one degree Fahrenheit temperature increase during the 20th century means we are all doomed. First of all, the one degree Fahrenheit rise coincided with the greatest advancement of living standards, life expectancy, food production and human health in the history of our planet. So it is hard to argue that the global warming we experienced in the 20th century was somehow negative or part of a catastrophic trend.
Second, what the climate alarmists and their advocates in the media have continued to ignore is the fact that the Little Ice Age, which resulted in harsh winters which froze New York Harbor and caused untold deaths, ended about 1850. So trying to prove man-made global warming by comparing the well-known fact that today’s temperatures are warmer than during the Little Ice Age is akin to comparing summer to winter to show a catastrophic temperature trend.
In addition, something that the media almost never addresses are the holes in the theory that C02 has been the driving force in global warming. Alarmists fail to adequately explain why temperatures began warming at the end of the Little Ice Age in about 1850, long before man-made CO2 emissions could have impacted the climate. Then about 1940, just as man-made CO2 emissions rose sharply, the temperatures began a decline that lasted until the 1970’s, prompting the media and many scientists to fear a coming ice age. Let me repeat, temperatures got colder after C02 emissions exploded. If C02 is the driving force of global climate change, why do so many in the media ignore the many skeptical scientists who cite these rather obvious inconvenient truths?
Read the whole thing.
Senator Inhofe mentions a letter sent last April by 60 prominent scientists to the Candian Prime Minister, warning the real evidence does not support the drastic theories commonly being advanced.
How often does anything this sensible or illuminating come out of the US Senate?

Paleontologists excavating in the Riversleigh Fossil Beds (also) in Northern Australia have made some exciting finds:
Palaeontologists digging in northern Australia claim to have found the fossilised remains of the ultimate fighting marsupial – a flesh eating “killer kangaroo” that had wolf-like fangs and once walked the earth more than 10 million years ago.
The team from the University of New South Wales made the discovery along with 20 other previously unknown species in northern Queensland, including the carnivorous kangaroo, known as Ekaltadeta, and a large predatory bird described by the team as a “demon duck of doom”.
The vertebrate palaeontologist Sue Hand said the meat-eaters would have looked remarkably different from kangaroos around today. “These things had slicing crests that could have crunched through bone and sliced off flesh,” she said.
Professor Michael Archer, another team member, described the remains of two kangaroo species, one with wolf-like fangs and another with long forearms that was unable to hop like a modern kangaroo. “Because they didn’t hop, these were galloping kangaroos, with big, powerful forelimbs. Some of them had long canines like wolves,” he said.
The killer marsupial and duck of doom flourished in the Miocene epoch.

Yale University received subpoenas from the Department of Health and Human Services, the Department of Defense, and the National Science Foundation requesting 10 years of the university’s financial records connected with some 47 Federal research grants amounting to approximately $45 million dollars.
WebCPA:
A February report by the Department of Health and Human Services that referred to a gene research program found that more than a third of the university’s more than $500,000 in invoices did not comply with federal standards, and costs were improperly transferred across budget cycles to make up for shortfalls.
“Regardless of the outcome of the current investigation, we must get all our processes right and make sure that we are good stewards of the funds entrusted to us by the federal government,” Yale president Richard Levin said in a statement.
The most detailed press reports seem to indicate that the discrepancies are associated with stem cell research.

The Antikythera Mechanism was a specialty of a good friend on the Yale faculty, the late Derek de Solla Price, and he often talked about the intriguing questions connected with the object recovered by sponge divers off the Greek Island of Antikythera in 1900, part of shipwreck dated to around 87 B.C.
Physorg.com reports that significant new progress has been made in reading the Greek inscriptions on the device.
A team of Greek and British scientists probing the secrets of the Antikythera Mechanism has managed to decipher ancient Greek inscriptions unseen for over 2,000 years, members of the project say.
“Part of the text on the machine, over 1,000 characters, had already been deciphered, but we have succeeded in doubling this total,” said physician Yiannis Bitsakis, part of a multi-disciplinary team of researchers from universities in Athens, Salonika and Cardiff, the Athens National Archaeological Museum and the Hewlett-Packard company.
“We have now deciphered 95 percent of the text,” he told AFP.
Scooped out of a Roman shipwreck located in 1900 by sponge divers near the southern Greek island of Antikythera, and kept at the Athens National Archaeological Museum, the Mechanism contains over 30 bronze wheels and dials, and is covered in astronomical inscriptions.
Probably operated by crank, it survives in three main pieces and some smaller fragments.
“(The device) could calculate the position of certain stars, at least the Sun and Moon, and perhaps predict astronomical phenomena,” said astrophysicist Xenophon Moussas of Athens University.
“It was probably rare, if not unique,” he added.
The rarity of the Antikythera Mechanism precluded its removal from the museum, so an eight-tonne ‘body scanner’ had to be assembled on-site for the privately-funded project, which used three-dimensional tomography to expose the unseen inscriptions.
The first appraisal of the Mechanism’s purpose was put forward in the 1960s by British science historian Derek Price.
