Gamer Chris Staniforth's death blamed on DVT

Gamer Chris Staniforth's death blamed on DVT

Chris Staniforth died from DVT Chris Staniforth would spend up to 12 hours playing on the console.

A man whose son died after playing video games for long periods is campaigning for greater awareness of the risk posed by their excessive use.

Chris Staniforth, 20, who would play his console for up to 12 hours, died in May from deep vein thrombosis (DVT).

His father David believes the condition may have been triggered by long gaming sessions.

DVT can form during long periods of immobility and can kill if the clots travel to the lungs.

Computer records showed his son would sometimes play online on his Xbox for periods up to 12 hours.

The coroner said a clot formed in Chris' left calf before moving to his lungs.

Once there, it caused a fatal blockage, known as a pulmonary embolism.

Mr Staniforth said: "After my research I saw there was no difference to Chris sitting at a desk on his Xbox and someone on a long-haul flight.

"Sitting still is literally the danger zone. Chris loved to play and would stay up all night.

"Millions of people worldwide are playing these games for hours, and there is a risk."

While Mr Staniforth has no problem with games consoles, he wants to highlight the heightened risk of DVT associated with being immobile, and is in the process of setting up a website.

In a statement, Microsoft, who manufacture the Xbox console, said: 'We have always encouraged responsible game play through our education campaigns such as Play Smart, Play Safe.

"We recommend that gamers take periodic breaks to exercise as well as make time for other pursuits."

Turkey: Military chiefs resign en masse

Turkey: Military chiefs resign en masse

The chief of the Turkish armed forces, Isik Kosaner, has resigned along with the army, navy and air force heads.

They were furious about the arrest of senior officers, accused of plotting, shortly before a round of military promotions.

A series of meetings between Gen Kosaner and PM Recep Tayyip Erdogan failed to resolve their differences.

Turkish President Abdullah Gul moved quickly to appoint General Necdet Ozel as the new army chief.

Gen Ozel is widely expected to be swiftly elevated to chief of the general staff in place of General Kosaner. Tradition dictates that only the head of the army can take over the top job.

There has been a history of tension between the secularist military and the governing AK party, with the two sides engaged in a war of words for the past two years over allegations that parts of the military had been plotting a coup.

Investigations into those allegations, known as the "Sledgehammer" conspiracy - appear to be the root cause of today's resignations, says the BBC's correspondent in Istanbul, with the senior military wanting to go ahead with scheduled annual promotions for some of the officers implicated - and the government refusing.

The Supreme Military Council, which will decide on promotions, is scheduled for next week.

The government says the top brass asked to retire.

But Gen Kosaner portrayed his resignation as a protest at the jailing of military officers in a variety of court cases.

"It has become impossible for me to continue in this high office, because I am unable to fulfil my responsibility to protect the rights of my personnel as the chief of general staff," Gen Kosaner told the Hurriyet news group.

'Sledgehammer'

Gen Kosaner and his senior commanders quit just hours after a court charged 22 suspects, including several generals and officers, with carrying out an internet campaign to undermine the government.

This case is the latest element of the protracted 'Sledgehammer' controversy - a coup plan allegedly presented at an army seminar in 2003.

Seventeen generals and admirals currently in line for promotion were among those jailed in the Sledgehammer prosecutions. Altogether nearly 200 officers were charged with conspiracy.

Twenty-eight servicemen will go on trial next month.

Gen Kosaner was appointed overall head of the Turkish armed forces just a year ago.

His appointment followed a period of intense friction between the government and the military over the Sledgehammer controversy.

At that point, the politicians vetoed the army's original choice for joint chief, Gen Hasan Igsiz, because he was implicated in the alleged plot.

Nato no comment

It reportedly involved plans to bomb mosques and provoke tensions with Greece, in order to spark political chaos and justify a military takeover.

The defendants have argued that the plot was a just theoretical scenario to help them plan for potential political unrest.

The dramatic mass resignation has particular resonance in Turkey, which endured a series of military coups from 1960 to 1980.

In 1997, an army-led campaign forced the resignation of the country's first Islamist-led government.

The joint resignation of military chiefs is thought to be unprecedented in Turkey, which is a Nato member.

In Brussels, a Nato spokeswoman declined to comment on the resignations.

Apple holding more cash than USA

Apple now has more cash to spend than the United States government.

Latest figures from the US Treasury Department show that the country has an operating cash balance of $73.7bn (£45.3bn).

Apple's most recent financial results put its reserves at $76.4bn.

The US House of Representatives is due to vote on a bill to raise the country's debt ceiling, allowing it to borrow more money to cover spending commitments.

If it fails to extend the current limit of $14.3 trillion dollars, the federal government could find itself struggling to make payments, and risks the loss of its AAA credit rating.

The United States is currently spending around $200bn more than it collects in revenue every month.

Apple, on the other hand, is making money hand over fist, according to its financial results.

In the three months ending 25 June, net income was 125% higher than a year earlier at $7.31bn.

Spending spree

With more than $75bn either sitting in the bank or in easily accessible assets, there has been enormous speculation about what the company will do with the money.

"Apple keeps its cards close to its chest," said Daniel Ashdown, an analyst at Juniper Research.

Industry watchers believe that it is building up a war chest to be used for strategic acquisitions of other businesses, and to secure technology patents.

Bookstore Barnes and Noble and the online movie site Netflix have both been tipped as possible targets, said Mr Ashdown.

The company may also have its eye on smaller firms that develop systems Apple might want to add to its devices, such as voice recognition.

Apple dipped into some of its reserves recently when it teamed-up with Microsoft to buy a batch of patents from defunct Canadian firm Nortel.

The bidding consortium shelled out $4.5bn for more than 6,000 patents.

Proof of America's low Taxes -- Evidence Shames T.E.A party (Taxed enough already Party)

Low taxes, high health costs make US choices tough

WASHINGTON (AP) - Wealthy countries all over the world are dealing with debts and strained budgets as they mop up after the Great Recession and brace for the budget-busting retirement of the baby boomer generation.

But the United States is in a bigger fix than almost anyone else.

The U.S. federal debt was equal to 95 percent of the overall economy in the first three months of 2011, the fifth-highest on the Associated Press Global Economy Tracker, an analysis of economic and financial data from 30 of the biggest economies.

Every year that the U.S. government spends more than it collects in taxes, it records an annual budget deficit. The $14.3 trillion debt is the sum of all annual deficits and surpluses.

As U.S. policymakers argue over raising the federal borrowing limit and slashing debts, America is hobbled in ways the others are not. Tax collections are low by historical and international standards. Health care costs are astronomical - and still rising. The political system is gridlocked.

Those problems suggest the current impasse over raising the U.S. government's borrowing limit and cutting the deficit is a prelude to even more intense political combat.

"We as a society will either have to pay more for our government, accept less in government services and benefits, or both," says Douglas Elmendorf, director of the nonpartisan Congressional Budget Office. "For many people, none of those choices is appealing - but they cannot be avoided for very long."

This year's federal tax revenues are forecast to equal 14.4 percent of gross domestic product, a broad measure of economic output, according to the Office of Management and Budget.

That's the lowest share since 1950, long before Congress approved expensive programs such as Medicare. Tax collections have been reduced by the recession and by tax cuts enacted in 2001 and 2003. Among 29 countries ranked by the Organization for Economic Development and Cooperation, only Japan and Spain take in less tax revenue than the U.S. as a percentage of GDP.

When it comes to health care, the U.S. spends the equivalent of 17.4 percent of its GDP - by far the highest percentage among wealthy nations. The next highest is the Netherlands, where health care spending equals 12 percent of GDP. Among the 34 wealthy countries that belong to the OECD, health care spending averages less than 9.5 percent of GDP.

Political gridlock magnifies America's debt woes. Among the five biggest countries with a top AAA rating from the credit rating agency Moody's, the U.S. is the only one that hasn't come up with a serious plan to control government debt, says Moody's sovereign debt analyst, Steven Hess.

The U.S. is also the only one of the five that doesn't have a parliamentary system, which allows the ruling party or coalition to pass its agenda undeterred by the opposition. After taking control last year in Britain, for instance, a coalition led by the Conservative Party enacted an austerity program of tax hikes and spending cuts.

The U.S. has a divided government - Democrats control the White House and Republicans control half of Congress. The effort to narrow annual budget deficits and reduce the debt has bogged down in partisan wrangling.

The AP Global Economy Tracker found most of the wealthy nations of the world struggling with high debt:

- Japan, which is aging rapidly and has endured more than a decade of economic stagnation, had the heaviest debt burden at the end of the first quarter: 244 percent of GDP. Economists Kenneth Rogoff of Harvard University and Carmen Reinhart of the Peterson Institute for International Economics say anything above 90 percent starts to weigh down economic growth partly by pushing up interest rates. Greece's debt was at 161 percent, Italy's 113 percent, Thailand's 111 percent and the United States' 95 percent.

- Energy-producing Canada and Norway had some of the lowest debt burdens among wealthy nations at 32 and 31 percent, respectively. The Norwegian government's finances are so strong that it issues debt mainly to ensure it has a functioning debt market and turns a profit by investing the money it borrows, says Nikola Swann, an analyst at credit rating agency Standard & Poor's.

- Fast-growing developing countries have a big advantage over rich countries when it comes to containing debts. They have younger populations and aren't facing a baby boomer retirement crunch. Brazil (28 percent) and Mexico (27 percent) had light debt burdens relative to GDP.

The U.S. does have a couple of advantages over other rich countries that help it hang onto its top credit rating even as its debts rise and political squabbling over the federal borrowing limit raises the risk of default.

Thanks to a relatively high birth rate and an even higher rate of immigration, the U.S. is aging more slowly than other rich countries. It will have a higher percentage of people working over the next few decades than Europe and Japan. Those workers will pay taxes to finance health care and pension benefits for baby boomers.

Last year, the U.S. had four active workers for every retiree; by 2050, with baby boomers out of the labor force, it will have only two, according to an S&P report on the fiscal impact of aging populations on rich countries. But the countries that are aging fastest - Japan and Italy - will have it much worse. An even split between workers and retirees will put enormous strains on their pensions and health care budgets.

Another U.S. advantage: The federal government's debts are all in U.S. dollars, giving America control of its destiny compared with countries that have to pay back debts in another country's currency. The U.S., for instance, can print dollars, driving down the value of the currency. That would make it cheaper to pay back its debts. It would also boost the economy and tax revenue by making American products cheaper around the world and luring foreign investors who build plants and buy real estate.

Cash-strapped Greece, by contrast, is tethered to a common European currency, the euro, and can't take advantage of a weaker currency. It's even worse for countries that owe money in another currency. Their debt payments go up if a currency they have borrowed in rises in value against their own.

Foreigners also like to own dollars, especially in times of crisis. That allows the U.S. Treasury to issue debt at low interest rates.

The U.S. debt burden isn't quite as heavy as it looks at first, either. The federal debt - $14.3 trillion - includes money the government has borrowed from itself, mostly revenue from Social Security. Take out the borrowing between government agencies and Uncle Sam's net debt drops to $9.8 trillion, or about 64 percent of GDP.

Some debt analysts consider Australia a model for the way it has controlled its budget and prepared to pay for an aging society. Over the last two decades, Australia cut government spending, imposed a 10 percent tax on most goods and services and sold off state assets including airports and railways. It also prepared to cope with an aging society by requiring employers to contribute toward a pension fund.

As a result, the Australian government's debts were equal to 14 percent at the end of the first quarter, lowest on AP's Global Economy Tracker.

This fact may not sit well: Americans are under-taxed

Kevin G. Hall | McClatchy Newspapers

last updated: July 12, 2011 06:46:19 AM

WASHINGTON — Here's a dirty little secret that most Americans don't want to hear: We're under-taxed.

That may sound like heresy; nobody wants to pay more taxes. But by historical standards, what we pay in federal taxes — rich, poor and everyone in between — has gone down.

At a time when Washington is wrestling with how to end federal budget deficits and trim the national debt — huge questions that are expected to dominate the nation's politics through the 2012 elections — the fact that Americans are under-taxed compared with U.S. historic norms is central to the discussion.

This fact is separate from the politically charged questions of whether government spends too much, the fairness of who pays how much and what we value or don't in government spending. It's simply that our tax burden is low in the long view of U.S. history, and there are many ways to measure that central truth.

One way is to look at the trend of total federal revenues, 81 percent of which come from income and payroll taxes, 9 percent from corporate taxes, 3.5 percent from excise taxes and 6.5 percent from other sources, according to the Office of Management and Budget.

The post-World War II historic average is that federal revenues equal about 18 percent of the U.S. gross domestic product, the broadest measure of annual economic production. In the year 2000, after the longest economic expansion in U.S. history, federal revenues equaled almost 21 percent of the economy. As a result, Washington cut taxes in 2001 and 2003.

Revenues plunged to around 15 percent of the economy in 2009 and 2010 amid the deep financial crisis, and dipped even further this year, to 14.4 percent, the lowest level since 1950.

Meanwhile, federal spending soared this year to 25.3 percent of the GDP, the highest since 1945, the last year of World War II.

The difference between spending and revenue yielded the federal budget deficit: $1.6 trillion this year, the highest ever.

Don't like that tax measure? Here's another:

Americans across all income classes paid lower effective tax rates in 2007, the last year of complete Internal Revenue Service data, than they did in 2000. The effective tax rate is what people pay after all exemptions and deductions. This is according to the most recent comprehensive look at taxes by the nonpartisan Congressional Budget Office.

The highest 20 percent of tax filers saw their total average federal effective tax rate fall from 28 percent in 2000 to 25.1 percent in 2007, according to the CBO. That's considerably lower than the current top marginal tax rate of 35 percent, and lower than the 27.5 percent effective rate in 1979, the first year that CBO data are available.

For the wealthiest 1 percent of filers, the effective tax rate fell from 33 percent in 2000 to 29.5 percent in 2007. The poorest 20 percent of filers saw their effective rate fall from 6.4 percent to 4 percent.

That's not to say the wealthy don't pay taxes — the top 1 percent paid 39.5 percent of all U.S. income taxes in 2007 — but taxes take a smaller share of their wealth today than historic post-World War II norms.

"They've been coming down for everybody, but we're taking more income at the top. Even if their rates are lower than they used to be, you are applying those lower rates to much larger income," said Roberton Williams, a senior fellow at the nonpartisan Tax Policy Center who spent 22 years as a CBO tax and income analyst. "The share of revenue being paid at the top end rises as their income rises too. But looking at the trend in effective rates, the rate has come down" for all income groups.

The CBO data are instructive because 2007 was the last year before the U.S. economy slipped into recession and nearly crashed. Comparing with 2000 is equally instructive because it's the final full year before the Bush-era tax cuts. They became the Obama tax cuts last December when he agreed to extend them until Dec. 31, 2012.

"It's hard to argue that we're overtaxed, and we're low by world standards," said David Wyss, the chief economist for the New York ratings agency Standard & Poor's.

Joseph Thorndike, a tax historian and visiting professor at the University of Virginia, concurred that Americans are "under-taxed relative to historical averages." However, he cautioned that what Americans pay in taxes can't be seen in isolation from what their government is spending.

"I think it's half of the discussion," he said. In his view, the high level of today's deficits and debt dictates two responses: Federal spending must fall and taxes must rise.

"The hard reality that people should be alerted to is these taxes are going up. They have fallen for most of us to varying degrees, but it is hard to imagine a scenario where they don't all go up."

Still doubtful?

There's yet another way to gauge the tax burden, using data from the Commerce Department's Bureau of Economic Analysis that go back to 1929. The bureau's data on personal income make it possible to guess roughly what portion of income goes to the taxman.

Under this calculation Americans on average saw 17.3 percent of their income go to federal taxes in 2009 and 2010. The last time the percentage was this low was 1975, and during the late 1960s.

If you exclude social insurance taxes on wages — for Medicare and Social Security — the share of taxes as a percentage of income drops to 9.4 percent in 2009 and 9.3 percent in 2010, the lowest since 1950.

The overall tax burden rose sharply in the late 1960s, as Americans began paying for Medicare, which was created in 1965. The burden rose again in 1983 with an increase in tax for Social Security. And tax revenue reached record levels in the late 1990s because the economy was booming and people moved up the tax ladder as they grew wealthier.

Whatever the facts, however, Americans think they're overtaxed, and polls show that they've thought that to be true for more than 50 years.

The American Enterprise Institute, a conservative research center, in April updated its report on "Public Opinion on Taxes: 1937 to Today."

Never have more than 3 percent of Americans thought their taxes were too low, the institute's poll research shows. And never have more than half of Americans considered their taxes "about right," although in 2003 that was the answer for exactly 50 percent of respondents to a Gallup poll.

For most of the period between 1980 and 2000, more than 60 percent of poll respondents thought their taxes were too high. This number dropped sharply beginning in 2003 — perhaps partly because tax rates also declined — falling to less than half of respondents for most years since then. It was 48 percent in a Gallup poll in April 2010.

Why do so many people think their taxes are too high, in good times and bad?

"I think people see a real disconnect between what they pay in and what they get out. We pay a lot for defense, yet we don't have a tangible sense of what we actually spend in Afghanistan or Iraq. Almost half of unemployment insurance recipients say they've never benefited from a government program," said Andrew Fieldhouse, an economist with the liberal Economic Policy Institute.

Fixing America - 14 Solutions for our 21st Century

  • 1. Public Campaign Financing. Buy the politicians or someone else will, such as big business. Right now the constituents of the politicians are big business interests. We need that to change.
  • 2. Tax reform = Increase Revenues. U.S revenues at record lows not seen since 1950's, at 14% of GDP. Higher revenues, lower debt, and more public goods.
  • 3. Defense spending tripled from 1997, needs to be lowered. End wars in Afghanistan, Iraq, Libya, and Yemen.
  • 4. 2008 financial collapse solution = Taxing speculators and taxing Derivatives markets. Reintroduce Glass-Stiegal and other regulations cut in the 90's.
  • 5. FIX HEALTH CARE = 17% of GDP, completely unacceptably high cost. Enact Universal Healthcare.
  • 6. Get rid of Judicial review as it's unconstitutional. If unable, hold Justices more accountable to public.
  • 7. Drug war is a failure, end it. Criminalizing drugs creates black markets.
  • 8. Invest in Jobs and Public infrastructure. Nearly 1 trillion dollars needed to fix existing American infrastructure issues.
  • 9. Foreign Policy: Pressure Israel to create a framework for peace since they seem to be holding back not accepting Obama's 1967 borders with swaps.
  • 10. Immigration: Allow children of Illegal immigrants that were brought here and do well, to have a path to citizenship. Overall immigration reform is also needed.
  • 11. Invest in Renewable Energy solutions aiming for 70%(~2/3) of America's energy to be renewable by 2033.
  • 12. Reform Education and provide Higher education beyond K-12 for all citizens.
  • 13. Prison industrial complex: Make privatization of prisons illegal. Privatized prison systems lead to corruption and the only way to increase profits and lobby to gate more inmates.
  • 14. Re-evaluate trade policies so as not to entice businesses to go overseas. Try to keep a robust trade policy that discourages large trade deficits.

Nature's hidden prime number code

Nature's hidden prime number code

Cicada with 17-year life cycle

Prime numbers are found hidden in nature, but humans have made spectacular use of them, writes mathematician Marcus du Sautoy.

Ever since humans evolved on this planet we have been trying to make sense of the world around us.

We have attempted to explain why the world looks and behaves the way it does, to predict what the future holds. And in our search for answers we have uncovered a code that makes sense of the huge complexity that confronts us - mathematics.

By translating nature into the code of numbers we have revealed hidden structures and patterns that control our environment.

But not only that. By tapping into nature's code we have been able to change our surroundings, have built extraordinary cities, and developed amazing technology that has resulted in the modern world.

Buzzing quietly beneath the planet we inhabit is an unseen world of numbers, patterns and geometry. Mathematics is the code that makes sense of our universe.

Only found in the eastern areas of North America, this cicadas survival depends on exploiting the strange properties of some of the most fundamental numbers in mathematics - the primes, numbers that are only divisible by themselves and one.

The cicadas appear periodically but only emerge after a prime number of years. In the case of the brood appearing around Nashville this year, 13 years. The forests have been quiet for 12 years since the last invasion of these mathematical bugs in 1998 and the locals won't be disturbed by them again until 2024.

This choice of a 13-year cycle doesn't seem too arbitrary. There are another two broods across north America that also have this 13-year life cycle, appearing in different regions and different years. In addition there are another 12 broods that appear every 17 years.

You could just dismiss these numbers as random. But it's very curious that there are no cicadas with 12, 14, 15, 16 or 18-year life cycles. However look at these cicadas through the mathematician's eyes and a pattern begins to emerge.

Because 13 and 17 are both indivisible this gives the cicadas an evolutionary advantage as primes are helpful in avoiding other animals with periodic behaviour. Suppose for example that a predator appears every six years in the forest. Then a cicada with an eight or nine-year life cycle will coincide with the predator much more often than a cicada with a seven-year prime life cycle.

These insects are tapping into the code of mathematics for their survival. The cicadas unwittingly discovered the primes using evolutionary tactics but humans have understood that these numbers not just the key to survival but are the very building blocks of the code of mathematics.

Every number is built by multiplying primes together and from numbers you get mathematics and from mathematics you get the whole of science.

But humans haven't been content simply with observing the importance of these numbers to nature. By understanding the fundamental character of these numbers and exploring their properties humans have literally put them at the heart of the codes that currently protect the world's cyber-secrets.

The Code Challenge

The Code prize
  • A treasure hunt is running alongside the show
  • There are three visual clues in each episode as well as other clues
  • The prize is a specially commissioned mathematical sculpture

The cryptography that keeps our credit cards secure when we shop online exploits the same numbers that protect the cicadas in North America - the primes.

Every time you send your credit card number to a website your are depending on primes to keep your details secret. To encode your credit card number your computer receives a public number N from the website, which it uses to perform a calculation with your credit card number.

This scrambles your details so that the encoded message can be sent across the internet. But to decode the message the website uses the primes which divide N to undo the calculation. Although N is public, the primes which divide N are the secret keys which unlock the secret.

The reason this is so secure is that although it is easy to multiply two prime numbers together it is almost impossible to pull them apart. For example no one has been able to find the two primes which divide the following 617-digit number:

The primes are the atoms of the arithmetic. The hydrogen and oxygen of the world of numbers.

But despite their fundamental character they also represent one of the greatest enigmas in mathematics. Because as you count through the universe of numbers it is almost impossible to spot a pattern that will help you to predict where the next prime will be found.

We know primes go on for ever but finding a pattern in the primes is one of the biggest mysteries in mathematics. A million-dollar prize has been offered to anyone who can reveal the secret of these numbers.

Despite having cracked so much of nature's code the primes are as much an enigma today as when the cicadas in the forests of Tennessee first tapped into them for their evolutionary survival.

In Steinbeck's footsteps: America's middle-class underclass

In Steinbeck's footsteps: America's middle-class underclass

On the road

In The Grapes of Wrath, John Steinbeck describes the harrowing journey of the Joad family - migrant workers forced to leave their home during the Great Depression - a story still relevant to those facing the realities of America's current economic crisis.

"To the red country, and part of the gray country of Oklahoma the last rains came gently, and they did not cut the scarred earth…" That is how Steinbeck begins The Grapes of Wrath.

This year the last rains came in May to western Oklahoma. They lasted long enough to produce the last alfalfa crop but the winter wheat was already lost.

Farm in Oklahoma The drought in Oklahoma has been described as worse than the Great Dust Bowl days of the 1930s

Brett Porter, who farms 3,000 hectares, unrolls the last of his hay in front of a thirsty line of prime Angus cattle. With just 18 bales left, and at $200 (£123) a bale on the open market, when he runs out he will have to sell the cows.

"I already sold half my mamma cows and I sent my calves to market early," he says.

He has been working on the herd's DNA for 12 years. If no rain comes, he will sell the rest for hamburger meat before high summer.

With the south-west in the grip of its worst drought for 60 years, old-timers here are beginning to talk about the Dust Bowl years, years Steinbeck chronicled in his Pulitzer Prize-winning book of migration, poverty and social injustice.

I decided to retrace the route Steinbeck's fictional family took from Oklahoma City to Bakersfield, just north of Los Angeles. I hired a boaty old Mercury and put my foot down.

Today the road is just one straight freeway, Interstate 40, though the old Route 66 of blues legend still weaves along as a forlorn side-road.

Video: 'Promised land' Video: 'Sheriff, Phoenix' Video: 'Jobless, Alburquerque' Video: 'Farmer, El Reno' Map: Retracing the Grapes of Wrath Route

After the Texas panhandle, scorched by drought so white that the grass crunches underfoot like in a deep frost, I hit New Mexico. Here the landscape changes to mesas and gulches.

I drop down into Albuquerque, into Joy Junction, which in the red dusk looks like a scene from Steinbeck. There are 300 homeless people staying here, all families.

Jeremy Reynalds, an expat Brit who runs the place, tells me frankly that the mainstay of the place are people with drug, alcohol and domestic violence issues. But as the years of crisis have dragged on, there is a new phenomenon - the homeless middle-class.

Maurice Henderson and RoseAnna Ortice and their sons Maurice Henderson has been unemployed for eight months

I meet some of them on the floor of an old gym, strewn with about 80 mattresses.

Sonya and Tim - he was a manager at McDonald's but the branch closed and she worked at Subway but they cut her shifts - lost their home and moved into a small apartment, but when the unemployment money ended they lost that too.

"We slept in our car, it was scary," says Sonya. "Then we came here."

Larry Antista and his 14-year-old daughter Michelle are bedding down alongside 80 people they do not know. Does her school know she is homeless? "I didn't tell them," Michelle says. "I stay there until six o'clock to do my homework." They lost their apartment when the family split up.

Maurice Henderson and RoseAnna Ortice are across the parquet floor with their three kids. Maurice used to manage a car dealership. They lived in a motel. The day his unemployment cheque did not arrive was the day he had to leave the motel and come here. They have been on the mattresses for two weeks.

There is wrath aplenty here - though you seldom hear such thoughts expressed on the US media. "They're wasting money on wars," says Larry. Maurice tells me the same thing. A guy crawls over his large family and almost whispers to me, "I'm Native American. My tribe runs a casino so where does the money go? Why don't they use it to help their own people?"

Motel hopping

Though the Okie camps of the 1930s are emblematic now - as are the dustbowl photographs of Dorothea Lange - it is easy to forget they were not front and centre of the nation's consciousness in the 1930s.

Steinbeck, who had lived in California most of his life, had to be alerted to the existence of the camps on his doorstep by Lange's husband, an academic, who wrote one of the first field reports of the migrant problem. Then, as now, the poor had only a walk-on part in the mass media, and their script lines seldom reflected what they actually thought.

Two men walking towards Los Angeles Dorothea Lange is best known for her photos taken during the Great Depression

All along Interstate 40 I have been cursing the motelscape. The inedible sludge of reconstituted egg, "biscuit" and gravy that allows them to advertise "hot breakfast" - the coffee weak enough to read the Wall Street Journal's markets pages through.

Reynalds takes me to a line of cheap motels right by the interstate where rooms are $29 (£18) a night. "These places fill up in the first two weeks after the benefit cheques are paid and when they run out, they empty out and people drift over to Joy Junction."

Now I see the cheap motels in a new light. This is where America's hidden homeless live.

Tent City jail

As I leave New Mexico and tank west beneath the mighty Mogollon Rim and into pine forest and then the cactus-strewn desert, one thing becomes clear... Steinbeck cannot have made this journey in one go.

The spectacular landscape is absent from the book - the Pueblo nation's shacks and trailers, the emptiness.

For the 350,000 real-life migrants - farmers, unemployed workers, office workers - who made the journey during the Dust Bowl years (1931-36) this must have seemed as alien as the Moon.

But Steinbeck is not about landscape, biblical though The Grapes of Wrath reads. It is about the conflict at the end of the journey and today you don't have to get to the end of the journey to find conflict.

Tent City Jail Tent City Jail was set up by Sheriff Joe Arpaio, known for his strong views on illegal immigration

In Phoenix, Arizona, I get to tour the Tent City jail. Prisoners wear stripes, pink socks, pink underwear and are forced to live, day and night, in Korean War-era tents.

On the day I arrive the mercury's thermostat tells me it is 114F (45.5C). They must remove their pink towels from their heads, even in harsh sunlight. And they must pay "premium rates" my guide tells me, for their landline calls, "to help pay for the cost of incarceration".

One in five of the male prisoners is a detained illegal migrant. After their sentence, they will go into the deportation process. The jail - like the border fence and Arizona's famous new law SB1070 - is designed to deter migration. But neither deter it.

There are, say migrant activists, an estimated 1.5m illegal migrants in Arizona.

Fernando Lopez, aged 20, was caught driving without a licence and has no documents that prove his right to stay here. He says he was shunted for a month around the Arizona detention system before being released on bail. He is fighting deportation now.

Fernando Lopez

[The jail] is designed to make us self-deport”

Fernando Lopez Tent City jail inmate

"People still come, because of the conditions across the border," he tells me. The North American Free Trade Agreement, he believes, has bankrupted small business in Latin America, and the same rural poverty you find the whole world over simply drives people to move north.

Leticia Ramirez, an activist with the migrant campaign group Puente, tells me the effect of the unique Arizona laws that make it possible to be lifted off the street if you cannot prove your status, is chilling. "Kids say to their moms, 'Mom, don't go to the store. Don't leave the house'." Thousands stay at home in fear, she says.

But attitudes are polarised. At the West Valley Tea Party Patriots meeting I attend, campaigners for migrants are accused of being "communists". I ask about the imminent debt ceiling crisis and they hand me a dossier claiming to prove President Barack Obama is really Kenyan.

I ask about migration. The Patriots are raising money to build a private border fence.

Can they understand why the migrants come? Yes, but they believe it will not harm the US economy if the whole 12m-20m estimated to live in the US are deported.

You can't jail them all, I venture. "Just build a bigger tent," says Karen Szatkowski, their spokesperson.

And there is evidence that the jail conditions, the aggressive policing and the laws that have prompted an economic boycott campaign against Arizona, are working. Anecdotally, around 100,000 migrants have gone elsewhere.

"It's designed to make us self-deport," says Fernando Lopez.

Tension and conflict around migration here is more intense than anywhere in the US.

Meanwhile the economy declines. Arizona is still in recession and the radio sings to adverts for repossessed ranches in the desert. "You can hunt there, ride, anything you want... it's your ranch!" urges the disc jockey, perkily.

'Morning glow'

Here the gas stations are far apart and the Mojave desert is wide, so I have timed my refills rigorously against the distances on the GPS.

But the GPS does not agree with the mercury's fuel gauge, so I glide into a truck stop at Cedar Hills in neutral gear, having run eight miles (13km) on empty.

The shop is full of stuff that is emblematic - the stimulant drinks in yellow bottles that keep truck drivers going all night, confederate flag-themed headscarves to wear on your Harley instead of a helmet, Route 66 stickers. Like so much of American culture, the subtext - if you dare admit it - is "we were great once".

San Joaquin Valley The city of Bakersfield lies at the southern end of the San Joaquin Valley in Kern County, California

I cross the Mojave by night and get to Bakersfield at midnight.

The bar at the hotel is full of oilmen and military guys. The economy of Kern County, where the Joads ended up, is dominated by the Air Force, naval weaponry, big oil and private healthcare.

But there is still 15% unemployment here. The town grew by 25% in the past decade but now the property bust is here, 156 homes in every thousand are repossessed.

In the morning, the car valet - a Mexican - tells me the agricultural work is drying up. The farmers sold their fields for property. You can only earn the minimum wage.

I go in search of the spot where Steinbeck must have seen this - "They drove through Tehachapi in the morning glow, and the sun came up behind them and then suddenly they saw the great valley below them…"

But the interstate highway obliterates the old road here. I drive into a vineyard to get the view that must have greeted the real-life Okies as they crossed the mountains into the San Joaquin Valley.

It is still beautiful. But hidden away from the mainstream media you can still find stories of social conflict and poverty that tell the other side of the story.

When he wrote the novel in 1939, Steinbeck pointed to a new economic model that would sustain the economic recovery, create jobs and drive the US into the era of prosperity and full employment.

That is the question that still confronts the US, as its president and legislature - as the Onion magazine so wryly put it - "continue the debate over whether the country should be economically ruined".

Fragmented sleep 'harms memory'

Fragmented sleep 'harms memory'

Woman asleep Continuous sleep is important for memory formation

Related Stories

Broken sleep affects the ability to build memories, a study of mice suggests.

The Proceedings of the National Academy of Science findings could help explain memory problems linked to conditions including Alzheimer's and sleep apnoea.

The Stanford University found disrupting sleep made it harder for the animals to recognise familiar objects.

A UK sleep expert said the brain used deep sleep to evaluate the day's events and decide what to keep.

This study looked at sleep that was fragmented, but not shorter or less intense than normal for the mice.

It used a technique called optogenetics, where specific cells are genetically engineered so they can be controlled by light.

They targeted a type of brain cell that plays a key role in switching between the states of being asleep and being awake.

Mouse memory test

The researchers then sent light pulses directly into the brains of mice while they slept.

"There are some things that we need to 'lock down' as a permanent hard memory”

Dr Neil Stanley Sleep expert

This meant they could disrupt their sleep without affecting total sleep time or the quality or composition of sleep.

The animals were then placed in a box with two objects, one of which they had encountered before.

Mice would naturally spend more time examining the newer object, and those who had been allowed uninterrupted sleep did just that.

But those whose sleep had been disrupted were equally interested in both objects, suggesting their memories had been affected.

Writing in the journal, the researchers, led by Dr Luis de Lecea, said: "Sleep continuity is one of the main factors affected in various pathological conditions that impact memory, including Alzheimer's and other age-related cognitive deficits."

Broken sleep also affects people addicted to alcohol, and those with sleep apnoea - a condition in which the throat repeatedly narrows or closes during sleep, restricting oxygen and causing the patient to wake up.

The researchers add there is no evidence of a causal link between sleep disruption and any of these conditions.

But they added: "We conclude that regardless of the total amount of sleep or sleep intensity, a minimal unit of uninterrupted sleep is crucial for memory consolidation."

Independent sleep expert Dr Neil Stanley, a former chairman of the British Sleep Society, said: "During the day, we accumulate all these memories.

"At some point we have to sort through what's happened during the day.

"There are some things that we need to 'lock down' as a permanent hard memory.

"That process occurs in deep sleep. So anything that affects sleep will have an effect on that process to a greater or a lesser extent."

Dr Stanley said there was particularly striking evidence that people with sleep apnoea had particular problems "locking down" memories.

And he added that people with Alzheimer's often had trouble sleeping, but said: "There is something there. But whether it's the degeneration of the brain that causes poor sleep, or poor sleep that aids the degeneration of the brain has not been determined."

Circumcision: Rwanda's quick cut to fight HIV

Circumcision: Rwanda's quick cut to fight HIV

A man being circumcised in Rwanda The WHO says male circumcision could reduce transmission of HIV by up to 60%

Related Stories

Circumcision in heterosexual males could reduce HIV by up to 60%, according to the World Health Organization (WHO). In Rwanda, Matthew Stein looks at government efforts to convince men to consider circumcision through a new non-surgical procedure that is cheaper, cleaner and more accessible.

In a cool room in Kigali's Kanombe Military Hospital a group of camera and notebook-toting doctors, nurses and researchers are standing to attention.

On request of the consultant doctor, the young man standing in the middle of the room calmly lowers his trousers.

He is here to reveal the results of his nine-day old circumcision, a new, non-surgical procedure for adults which is being tested in Rwanda.

A thick gauze bandage, which was placed around the tip of his penis after his foreskin was removed two days earlier, is clean and without blood.

Dr Jean Pierre Bitega, the specialist who oversaw the operations explains: "We want to see if, in the future, a patient can remove the dressing alone at home."

In an adjacent room, 21-year-old Richard Muheto is preparing to undergo the same circumcision procedure.

A student from Bugesera in south-east Rwanda, Mr Muheto says he has long wanted to be circumcised to reduce his risk of contracting HIV and "to be a cleaner person for washing".

Wasting no time

In 2010, the WHO said there was compelling evidence that circumcision can reduce the risk of HIV infection by around 60% in high risk areas such as sub-Saharan Africa.

However, those involved in the fight against Aids stress that using condoms and staying faithful to one partner offer far more reliable protection.

Circumcision device components In the future, patients may be able to perfom the procedure at home

Experts give several reasons for this including that the foreskin traps HIV in a moist environment allowing the virus to live longer.

But until recently this was unaffordable for people like Mr Muheto.

Then he heard from a colleague that the government was offering a "new kind" of non-surgical circumcision which was free of charge. He wasted no time in signing up.

The new procedure involves the use of a device called a PrePex, a three-piece mechanism consisting of two plastic rings and an elastic mechanism.

It is clamped onto the penis without any need for sutures or anaesthesia. As such the procedure can be done in any clean, sheltered environment releasing Rwanda's already stretched surgical theatres for more urgent matters.

Moreover, using the device is simple and can be taught to nurses in just two days, allowing medical professionals to concentrate on other complex operations.

"We had been waiting for this innovation but until the PrePex we didn't have it," says Rwandan Health Minister Agnes Binagwaho.

In fact, Rwanda became so intrigued with PrePex that it sent two of its own health specialists, Dr Bitega and Leon Ngeruka, to help the American manufacturer, Circ MedTech, improve the device for the country's particular environment.

Since then, Rwanda has been conducting its own PrePex studies to satisfy WHO standards.

'No pain'

The objective is to scale up use for a mass circumcision initiative across the country.

The campaign, which was launched in December 2010, intends to halve Rwanda's current HIV incidence rate of 3% by circumcising two million men by the end of 2012.

Since early May, nurses have been undergoing a two-day training course as opposed to the 15 days it takes to learn surgical circumcision. By mid-May, says Dr Bitega, six nurses had successfully graduated and 10 more were expected by June.

We've had zero infections”

Dr Jean Pierre Bitega

Mr Muheto is impressed by the swiftness of the procedure and says there is no pain to report. For good measure, he will receive two oral painkillers, but will be discharged immediately. A week later he must return to have his foreskin removed.

Since the campaign began, Rwanda has circumcised 5,000 men but it can dramatically increase these figures.

The health ministry estimates that with 500 health facilities in the country Rwanda can perform approximately 250,000 procedures every two weeks.

However, circumcision is still a foreign concept to Rwandans. Only 15% of adult males are circumcised. In rural areas, where illiteracy is high and traditional customs are more entrenched, this falls to as low as 1-2%.

The government has launched a public education sensitisation campaign on the radio with the help of local leaders and community health workers.

"When the service is available the community complies," says Corine Karema, acting director of the Treatment and Aids Research Centre. "When it's the government that plans they know it's for their better health."

Innocent Mpirimbanyi, the health and education officer for Ndera village near Kigali, had only heard about the sensitisation campaign from radio advertisements. "I haven't received any documentation on this subject," he says.

But the procedure has yet to receive full approval from the WHO. Without this, funding from organisations like the UN's Global Fund or Pepfar, the United States President's Emergency Fund for Aids Relief, will remain out of reach.

The European Union has already endorsed PrePex but the WHO needs ample clinical data to inform its decision. It requires that a given device be tested in different contexts before it is approved, explains Kim Dickson, a senior adviser in the WHO's HIV/Aids department.

But so far the data received from Rwanda has been "extremely promising", she says.

For local Rwandan officials the viability of the new method is beyond doubt. "We've had zero infections," says Dr Bitega, "it's perfect every time."

Why Chile is an astronomer's paradise

Why Chile is an astronomer's paradise

Inside one of the telescopes and the control room at Paranal observatory

Related Stories

With its crystal clear skies and bone dry air, the Atacama Desert in northern Chile has long drawn astronomers. Some of the most powerful telescopes in the world are housed here.

But now, work is about to begin on a telescope that will dwarf them all - not a VLT (Very Large Telescope) but an ELT (Extremely Large Telescope).

It will be built 2,600m (8.530ft) up in the Andes on a site overlooking the Paranal observatory, and when it is finished in 10 years' time it will be the most powerful optical instrument in the world.

The telescope will be the size of a football stadium, cost around $1.5bn (£930m) and weigh over 5,000 tonnes.

It will be built to withstand major earthquakes, a serious consideration in Chile.

Jigsaw puzzle

Astronomers say the images it produces will be 15 times sharper than those sent to earth by the Hubble space telescope, and might eventually help us find signs of life on other planets.

The European Southern Observatory (ESO), which operates Paranal, says the telescope, and others like it, "may eventually revolutionise our perception of the universe as much as Galileo's telescope did".

The telescope's main mirror will be 42m wide. That is five times bigger than the mirrors on the existing telescopes at Paranal, which are already among the biggest in the world.

Because it is impossible to make such a large, curved, high-precision mirror, engineers in Europe will make nearly 1,000 small hexagonal mirrors which will be shipped to Chile and fitted together like pieces in a giant jigsaw puzzle.

Henri Boffin, a senior astronomer at Paranal, says the new telescope should help scientists address questions raised by the existing instruments at the observatory.

"What we have been able to do so far is raise a set of questions," Mr Boffin said. "Like, for example, we have discovered that the expansion of the universe is accelerating, but we have no clue why.

"There's a kind of dark energy we think is there, but we have no clue at all what it is. Similarly, we know that the universe is made in part of dark matter, but we have absolutely no clue what it is, and it makes up more than 25% of the universe.

"The new telescope will hopefully help us answer these questions."

The construction of the telescope is not the only major astronomical project in Chile.

Just up the road from Paranal, engineers are completing the construction of ALMA, the world's biggest network of radio telescopes.

It consists of more than 60 giant radio dishes, assembled on the Chajnantor plateau at a dizzying altitude of 5,000m.

Tim de Zeeuw, the head of ESO, says ALMA, which is scheduled to begin operations later this year, promises to be "as transformational for science as the Hubble space telescope".

Desert dry

These two projects are cementing Chile's reputation as an astronomer's paradise. By some calculations, by 2025 the country will be home to more than half the image-capturing capacity in the world.

Much of the reason for that lies in the desert skies, which are among the clearest on earth. In some parts of the Atacama Desert, rainfall has never been recorded.

Altitude is also important, particularly for ALMA. Radio telescopes pick up wavelengths from outer space, but the signals are often distorted by water vapor in the earth's atmosphere.

By building at altitude, in dry air, engineers can get above some of that moisture.

Photo: ESO The telescopes in Chile have captured amazing information about the skies

But there are other reasons why astronomers are flocking to Chile.

Being in the southern hemisphere, its observatories are not in direct competition with those in the United States and Europe, which gaze out at different skies.

"If you want to do modern astronomy and you want to do it in the southern hemisphere, you have to do in Chile," Mr Boffin says.

Politics and infrastructure are also factors. Chile has emerged as one of the most stable, prosperous countries in the region since its return to democracy in 1990. That stability is essential for long-term investment projects like these.

The existing telescopes at Paranal have already helped scientists make some remarkable discoveries.

For example, they captured the first ever images of a planet outside our own solar system, and helped astronomers work out the age of the oldest known star in the Milky Way - it is 13.2bn years old.

One of the observatory's greatest feats was proving that a huge black hole lies at the centre of the Milky Way.

Scientists calculate that this mysterious void has a mass three million times larger than the Sun.

The astronomers at Paranal are proud of these achievements but say they now want more.
