to reach a deal. " I have decided to end discussions with the White House and begin conversations with the leaders of the Senate in an effort to find a path forward, " Boehner said in a letter to members of the House of Representatives. In a hastily announced public appearance, angrily assailed Boehner for quitting the table and said he was calling him and other top congressional leaders to the White House for talks at 11: 00 am ( 1500 GMT) Saturday. " We have run out time and they are going to have to explain to me how it is that we are going to avoid default. They can come up with any plans that they want and bring them up here and we will work on them, " the president said. " The only bottom line I have is that we have to extend this debt ceiling through the next election, " said Obama, whose bid for a second term in November 2012 will turn on his handling of the sour US economy.

Boehner' s move cast doubt on the fate of efforts to raise the $ 14. 3 trillion US debt limit by August 2, when the cash- strapped government of the world' s richest nation will run out of money to pay its bills. A House Republican leadership aide told reporters on condition of anonymity that Boehner believed he needed to have a detailed plan to present to House Republicans by Monday. The aide also said that the two sides had been on track for a package that would have cut some $ 3- $ 3.

5 trillion over 10 years. Washington hit its debt ceiling on May 16 but has used spending and accounting adjustments, as well as higher- than- expected tax receipts, to pay its bills and continue operating up to the deadline Finance and business leaders have warned failure to raise the US debt ceiling by then would send shock waves through the world economy, while Obama has predicted a default would trigger economic " Armageddon. " Obama and Boehner were at odds on a range of issues, but a key sticking point was the White House' s push for increasing tax revenues from the rich and wealthy corporations, something Republicans fiercely opposed. " A deal was never reached, and was never really close. In the end, we couldn' t connect. Not because of different personalities, but because of different visions for our country, " the speaker said in the letter. " The president is emphatic that taxes have to be raised.

As a former small businessman, I know tax increase destroy jobs. " Ahead of the announcement, met in Mc.

Connell' s office. A House Republican leadership aide said they had been briefed on the decision, which Boehner took Friday.

Mc. Connell said in a statement it was " disappointing" that the White House talks had failed to reach an agreement but that congressional leaders would now " develop a solution that will prevent default, without job killing tax hikes, while substantially reducing Washington spending. " " As I' ve said before, it' s time now for the debate to move out of a room in the White House and on to the House and Senate floors where we can debate the best approach to reducing the nation' s unsustainable debt, " said Mc. Connell.

Australia Thursday moved to introduce a legal right to privacy after the phone- hacking scandal in Britain, paving the way for people to sue media organisations for serious breaches. Laws are already in place to deal with criminal offences related to privacy abuses but there is no statutory right to sue. Home Affairs Minister Brendan O' Connor said he was acting now after the News of the World furore heightened concerns. " Right now there is no general right to privacy in Australia, and that means there' s no certainty for anyone wanting to sue for an invasion of their privacy, " said O' Connor, whose government is in a running battle with some Murdoch- owned publications. " The News of the World scandal and other recent mass breaches of privacy, both at home and abroad, have put the spotlight on whether there should be such a right. " Rupert Murdoch was grilled by British MPs this week over the outcry that saw him close British tabloid News of the World and dump his bid for satellite broadcaster BSky. B over the hacking of phones. would seek the views of the public immediately on introducing a right to privacy. " This government strongly believes in the principle of freedom of expression and also the right to privacy. Any changes to our laws will have to strike a balance between the two ideals, " he said. " Privacy is emerging as a defining issue of the modern era, especially as new technology provides more opportunities for communication, but also new challenges to privacy. " warned Murdoch' s Australian arm it faced some " hard questions" as calls intensify for a media inquiry following the explosive hacking crisis.

It followed senior ministers lashing out at Sydney' s Daily Telegraph newspaper, accusing the Murdoch- owned daily of being intent on bringing down the Labor- led minority coalition government.

Murdoch controls about two- thirds of Australia' s regional and metropolitan newspapers, has a stake in broadcasters Sky News and Fox Sports, and is angling to run the , the international public TV channel. In a scathing editorial, the mogul' s flagship newspaper here, , hit back Thursday, accusing the government of getting caught up " in the feeding frenzy against and our proprietor" . " The creeping opportunism of this government and its coalition partners, the Greens, in trying to use the cover of the News of the World scandal to put pressure on journalists in Australia is troubling, " it said. " Brendan O' Connor' s ambit claim for a statutory right of privacy makes an extraordinary leap from the British phone- hacking scandal to Australia, where such practices are unknown in journalism and already illegal. " , the conservative opposition' s communications spokesman, cautioned the government against linking its push for a statutory right to privacy with the phone- hacking scandal. " We really do need to make sure that any discussion doesn' t become a sort of antipodean re- run of the News of the World inquiries in the UK, " he told ABC radio. " If we' re going to look at privacy, we should look right across all media and have a honest debate about how much privacy we are entitled to.

The debate should also consider the media' s right of free speech. "

You' re sitting in a freshly drywalled house, drinking coffee from a plastic foam cup and talking on a cellphone. Which of these is most likely to be a cancer risk? It might be the sitting, especially if you do that a lot.

Despite all the recent news about possible cancer risks from cellphones, coffee, styrene, and formaldehyde in building materials, most of us probably face little if any danger from these things with ordinary use, health experts say. Inactivity and obesity may pose a greater cancer risk than chemicals for some people. " We are being bombarded" with messages about the dangers posed by common things in our lives, yet most exposures " are not at a level that are going to cause cancer, " said Dr. Len Lichtenfeld, the American Cancer Society' s deputy chief medical officer. Linda Birnbaum agrees. She is a toxicologist who heads the government agency that just declared styrene, an ingredient in fiberglass boats and Styrofoam, a likely cancer risk. " Let me put your mind at ease right away about Styrofoam, " she said.

Levels of styrene that leach from food containers " are hundreds if not thousands of times lower than have occurred in the occupational setting, " where the chemical in vapor form poses a possible risk to workers. " In finished products, certainly styrene is not an issue, " and exposure to it from riding in a boat " is infinitesimal, " she said. Carcinogens are things that can cause cancer, but that label doesn' t mean that they will or that they pose a risk to anyone exposed to them in any amount at any time.

They have been in the news because two groups that periodically convene scientists to decide whether something is a carcinogen issued new reports. Last month, the International Agency for Research on Cancer, part of the World Health Organization, said there is a possibility cellphones raise the risk of brain tumors. " The operative word is ' possibility, ' " said Lichtenfeld, who among others has pointed out the thin evidence for this and the fact that cancer rates have not risen since cellphones came out. Last week, the National Toxicology Program, part of the National Institute of Environmental Health Sciences — both of which Birnbaum heads — issued its report.

It adds to the list of known carcinogens formaldehyde, which is in building materials and some hair- straightening products, though Birnbaum said on- the- job exposure is the main concern.

The list also adds a plant substance in some " natural" arthritis remedies, aristolochic acid. Six other things were dubbed " reasonably anticited" to be carcinogens, including styrene and another herbal medicine ingredient, riddelliine ( rih- DELL- een) .

Since 1971, the international cancer agency has evaluated more than 900 substances. Just over 100 have been deemed carcinogens, 59 are called probable carcinogens, and 266 others are possible ones.

In this last category of possibles — besides the electromagnetic energy from cellphones — are coffee, engine exhaust and talc- based body powder. Talc in its natural form may contain asbestos, though products sold for home use since the 1970s have been asbestos- free.

Again, most risk is thought to involve occupational or unusual exposure to natural talc. The evidence on coffee has gone back and forth for years, with no clear sign of danger and some suggestions of benefit.

However, known carcinogens include alcoholic beverages, estrogen treatments for menopause symptoms, birth control pills, certain viruses and parasites, and even some drugs used to treat cancer, such as cyclophosphamide and tamoxifen. " Most people would probably be shocked to see the number of things they interact with every day" on these lists, Lichtenfeld said.

Here' s the problem: The agencies that pass judgment on a carcinogen don' t regulate it or determine what levels or routes of exposure are a concern and for whom. " People immediately assume it' s going to cause cancer at any exposure level, and that' s simply not true, " said A.

Wallace Hayes, editor of the scientific journal Food and Chemical Toxicology, and an industry consultant. The rule is " RITE" — Risk Is equal to Toxicity times Exposure — and " they' ve left out half of the equation" by not saying how much exposure is a concern, Hayes said. " The organizations that list these substances as possibly carcinogenic have to be conservative.

That means if there' s any reasonable evidence, way before it' s a sure thing, they have to say, ' Let' s be cautious. ' That' s their job — to raise the flag, " said David Ropeik, a consultant and author of " How Risky Is It Really?

Why Our Fears Don' t Always Match the Facts. " It' s human nature to fear risks we didn' t choose, such as hazardous chemicals, more than those we did, such as lack of exercise, poor diets or smoking, he said. " A risk that is imposed on us scares us more than a risk we take voluntarily, " especially if it comes from companies we don' t trust, Ropeik said. Styrene is an example: The government says it is a component of tobacco smoke and that is the biggest way most people are exposed to it. Smoking, of course, is the most easily preventable cancer risk.

To minimize risk, people can take reasonable measures to avoid exposure to possibly harmful things, experts say. " If you walk into a room and you can smell formaldehyde, you probably want to vent the room before you spend a lot of time in it. That' s just common sense, " Birnbaum said. If you' re concerned about pesticides, you can peel fruit and vegetables or choose organics, though there is some evidence that organic products may be less safe in terms of germs like E. coli and salmonella. People worried about cellphones can hold them farther from the head, text- message instead of talk, or use a headset or earpiece as Lichtenfeld does. He was returning from a major cancer conference in Chicago last week when a fellow traveler pointed at Lichtenfeld' s Bluetooth earpiece and said, " Do you know that thing can cause cancer? " " I said, ' Yes, ma' am, I' m very familiar with the data and I choose to use Bluetooth, ' " said Lichtenfeld, who didn' t tell her he was one of the biggest cancer experts she' d ever meet. " You can' t live life in fear, " he said. " You have to live life. " Carcinogens: http: / / bit. ly/ a.

Ahead of a crisis summit of euro zone leaders, said a short- term or selective default for Greece, previously opposed by , was now a possibility. EU sources said the European Central Bank is willing to let Greece slip into temporary default. Germany and France will later present details of the accord they thrashed out over seven hours on Wednesday to their fellow leaders, who are trying to prevent fears of a Greek default from poisoning access to the bond market for bigger euro zone states such as Italy and Spain. " The market was long and is quite nervous.

This talk of the possibility of a default and the package not being quite as neat as people expected from a banking point of view is not helping, " said Sebastien Galy, FX strategist at Societe Generale.

" Anything that comes out ( from the summit) needs to be really convincing to limit the risk of contagion to Italy and Spain which has materialized in the last few weeks, " said Derek Halpenny, currency strategist at . The dollar gained across the board, having earlier come under pressure on concerns about the debt talks in Washington. S. lawmakers and the White House are struggling to reach a deficit- reduction deal to raise the government' s $ 14.

There have been glimmers of hope in Washington this week for a compromise based on a broad deficit- cutting proposal from a bipartisan group of senators that could stave off default and salvage America' s triple- A credit rating.

But the stakes are so high and the divide so wide between President Barack Obama and his Republican rivals that negotiations could go down to the wire early next month.
