hey, delft, what does it mean? new Migration Period has begun maybe?

EDIT
by the way, what tribe was that? I would think they took the wrong way :)

I never heard the name of the tribe. Perhaps it was never recorded. They may have been called a tribe because they spoke a strange language.
At the time the people to the North East of the Roman Empire were under pressure from the people of the Eurasian steppe. These couldn't invade China because the Chinese were able to defend the Great Wall, they couldn't invade Persia I read somewhere because the Persians had a system similar to the later European feudalism and based on the use of alfalfa to feed the horses so they could use stronger and heavier horses than the steppe people. The Western part of the Roman Empire couldn't defend its borders and indeed became so weak that a small group of people could wander the length of Italy. Libya was still a civilized part of the World so it was a reasonable place to go. Think also of the "famous" Vandals who started out near the mouth of the Vistula and ended up in Tunisia. They themselves will have been a small part of the crews of the ships that took Rome in 455. They used the available "Roman" seamen.

There has been much speculation that that the "only" way to maintain a sufficient work force for the European economy would be to allow large numbers of immigrants as the natural production of children is insufficient. Europe might be able to achieve this by helping to destroy Libya, Syria, Iraq &c.

Carbon dating was developed from about 1950 and the first assumption was that the air always contained a constant amount of carbon dioxide with a radioactive C14 atom. However C14 is produced when a Nitrogen atom absorbs a slow neutron from cosmic radiation and ejects a proton and the flux of cosmic radiation depends on the activity of the Sun. So as far as possible radiocarbon dates are calibrated against known dates, for example from counted tree rings from trees found in bogs.

Actually, radiocarbon dating is done on the sample independently of other dating methods.

This is the original story that assumed that the relative amount of 14C in the atmospheric CO2 is constant. Around 1970 people started to compare the known dates of Egyptian artifacts with their radiocarbon dates and the differences were large. Therefore when possible radiocarbon dates were calibrated against initially wooden beams in old buildings that were chained together using dendrochronology. Later the chain was lengthened by using trees found in bogs and peat. You don't get back to 50 000 years of course but at any rate for the last 10 000 years or so radiocarbon dates are calibrated against real years.

A government agency reanimating a 30,000 year old virus, what can go wrong? Will they deliver it by mistake along with some inert anthrax? Instead of figuring out how to reanimate prehistoric viruses that might wipe humanity, should they not be spending it’s time trying to figure out how to kill the viruses that are currently afflicting mankind? Have they become that “bored” with HIV, Ebola, Shingles, influenza all the other nasty little viruses

Frankenvirus emerges from Siberia's frozen wasteland

Paris (AFP) - Scientists said they will reanimate a 30,000-year-old giant virus unearthed in the frozen wastelands of Siberia, and warned climate change may awaken dangerous microscopic pathogens.

Reporting this week in the flagship journal of the US National Academy of Sciences, French researchers announced the discovery of Mollivirus sibericum, the fourth type of pre-historic virus found since 2003 -- and the second by this team.

Before waking it up, researchers will have to verify that the bug cannot cause animal or human disease.

To qualify as a "giant", a virus has to be longer than half a micron, a thousandth of a millimetre (0.00002 of an inch).

Mollivirus sibericum -- "soft virus from Siberia" -- comes in at 0.6 microns, and was found in the permafrost of northeastern Russia.

Climate change is warming the Arctic and sub-Arctic regions at more than twice the global average, which means that permafrost is not so permanent any more.

Cells of the Mollivirus sibericum, a virus that was buried deep in the Siberian permafrost for over …

"A few viral particles that are still infectious may be enough, in the presence of a vulnerable host, to revive potentially pathogenic viruses," one of the lead researchers, Jean-Michel Claverie, told AFP.

The regions in which these giant microbes have been found are coveted for their mineral resources, especially oil, and will become increasingly accessible for industrial exploitation as more of the ice melts away.

"If we are not careful, and we industrialise these areas without putting safeguards in place, we run the risk of one day waking up viruses such as small pox that we thought were eradicated," he added.

In safe laboratory conditions, Claverie and colleagues will attempt to revive the newly discovered virus by placing it with single-cell amoeba, which will serve as its host.

Claverie, who runs a lab at France's National Centre for Scientific Research (CNRS), and a team discovered another giant virus, which they called Pithovirus sibericum, at the same location in 2013, then managed to revive it in a petri dish.


In 2004, US at a top-security lab at the Centers for Disease Control and Prevention (CDC) resurrecte …

Unlike most viruses circulating today, and to the general astonishment of scientists, these ancient specimens dating from the last Ice Age are not only bigger, but far more complex genetically.

M. sibericum has more than 500 genes, while another family of giant virus discovered in 2003, Pandoravirus, has 2,500. The Influenza A virus, by contrast, has eight genes.

In 2004, US scientists resurrected the notorious "Spanish flu" virus, which killed tens of millions of people, in order to understand how the pathogen was extraordinarily so virulent.

US researchers flew to Alaska to take frozen lung tissues from a woman who was buried in permafrost.

By teasing genetic scraps out of these precious samples and from autopsy tissues stored in formalin, the team painstakingly reconstructed the code for the virus' eight genes.

The work was done in a top-security lab at the US Centers for Disease Control and Prevention (CDC).

"Desperate" Chicago Schools Need Half Billion To Avoid Mass Layoffs, Partial Shutdown

Last month, we noted with some incredulity that Illinois is

lottery winners in IOUs. Long story short, the state’s inability to pass a budget means big winners will have to wait on their prize money, a ridiculous situation which prompted one Illinoisan to remind state officials that “if we owed the state money, they’d come take it and they don’t care whether we have a roof over our head; our budget wouldn’t be a factor.” State Rep. Jack Franks agreed, noting that the “government is committing fraud on the taxpayers.”

The lottery debacle is just the latest example of Illinois’ deepening fiscal crisis which was catapulted into the national spotlight in May when a state Supreme Court decision that struck down a pension reform bid prompted Moody’s to cut the city of Chicago into junk territory. Since then, the media has been awash with tales of the labyrinthine, incestuous character of the state’s various state and local governments and the deplorable condition of the state’s pension system.

The fallout from the budget crisis is far-reaching in the state with the latest example being Chicago’s public school system (the third-largest in the country), which opened this week with a budget shortfall of nearly a half billion dollars. Here’s
Please, Log in or Register to view URLs content!
:



Chicago Public Schools—with 394,000 students and nearly 21,000 teachers—has closed more than half of a projected $1.1 billion shortfall through cuts, borrowing and other means, but is looking to the state to come up with the rest. The school board warns of deep cuts later this year if Illinois, which faces its own fiscal crisis, doesn’t deliver an additional $480 million in the coming months, representing roughly 8% of annual district spending.



“It is like the board is a desperate gambler at the end of their run,” said Jesse Sharkey, vice president of the Chicago Teachers Union, in a recent speech.



“We are really now at a point where further cuts would reach deep into the classroom,” said Forrest Claypool, who was named chief executive of the city schools in July.



Since 2011, the school board has made nearly $1 billion in cuts—including $200 million this year that involved eliminating 1,400 positions, mostly through layoffs. Enrollment declines, due to shifting demographics and Chicago’s shrinking population, have led to school closings, including nearly 50 elementary schools in 2013 alone.



Mayor Rahm Emanuel has clashed with the teachers union, which went on strike three years ago and is currently without a contract. Another strike isn’t out of the question as the two sides are wrestling over the district’s effort to get teachers to pay more of their pension costs.



A group of parents, educators and activists with the support of union leaders launched a hunger strike Aug. 17 in a push to reopen a closed high school in a historically black neighborhood on the city’s South Side. The group argues the board concentrates money in Chicago’s wealthy, predominantly white neighborhoods. Hispanic and black students make up a vast majority of enrollment in city schools, and more than 85% of students are considered economically disadvantaged.

Of course one problem is a sharp increase in pension costs thanks to a “holiday” the board decided to take from 2011 through 2014:



The district’s pension costs have more than doubled in recent years after the board took a partial “holiday” for three years from paying the amount needed to put the retirement system on a path to long-term solvency.

And all the classic options - raising taxes, taking on new debt to payoff the old debt, etc. - have apparently been exhausted:



At first, the board drained reserves and paid off old debt with new, but those options are running out. The district also is raising property taxes as much as it can under a state cap. At the same time, Mr. Emanuel is weighing a much larger increase to confront the city government’s own pension problems, but that wouldn’t go to the schools.

Which means asking the ineffectual state legislature for $480 million, but thanks to gridlock in Springfield, there are no assurances that aid is forthcoming and that, in turn, means that once it's all said and done, the third largest school system in the country will be forced to layoff thousands and implement what amounts to a partial shutdown.



Senate President John Cullerton, a Chicago Democrat who sponsored the legislation, said without it the schools would see the layoffs of 3,000 teachers, increased class sizes and a shortened academic year. “We have to resolve this,” he said.

Yes, this has to be resolved and because we want to help, we suggest Governor Bruce Rauner not do things like squander hundreds of thousands of dollars in taxpayer money on celebrity budget gurus like Donna Arduin, who, until she was dismissed two Fridays ago for not being very guru-ish when it came to Illinois' budget, was making $30,000 a month or, more than half of what a Chicago public school teacher makes in a year.

What can one say?
