Men face earlier risk of colon cancer

Middle-aged men are twice as likely as women to end up with a cancer diagnosis after a colono-scopy, according to an Austrian study that challenges current screening guidelines. Currently, people at average risk of colon cancer start screening for the disease at age 50, regardless of gender. But the study, published in the Journal of the American Medical Association, shows a discrepancy of nearly 10 years between men and women in the development of colon and rectal tumors. The study found that colono-scopies would find one in 80 men aged 55 had cancer. This figure is also true for 65-year-old women. The same logic held for the pre-cancerous growths called advanced adenomas, which doctors also look for during colonoscopies. Lead researcher Monika Ferlitsch, of the Medical University of Vienna, said: "The prevalence and number needed to screen for advanced ade-nomas were comparable for men aged 45-49 and women aged 55-59." About one in 19 men develops colon cancer at some point and slightly fewer women do. The disease usually strikes older adults and is the third-leading cause of cancer deaths in the US. Ferlitsch and her team looked at data from more than 44,000 Austrians who had colonoscopies between 2007 and 2010.

'Son of star wars' base in Yorkshire finally ready to open

Peace campaigners slam secrecy over $10bn Menwith Hill project that puts UK in line of fire A "star wars" inspired defence shield that will alert the US to the launch of ballistic missiles is expected to be operational from a North Yorkshire airbase before the end of the year. The Space Based Infrared System is seen as the successor to Ronald Reagan's unrealised "star wars" programme, which would have detected Soviet missiles and shot them down using lasers. The new system, which has cost more than $10bn, has taken almost two decades to build and has been subject to numerous delays and cost overruns. The imminent completion of the project at the RAF Menwith Hill base near Harrogate has revived fears that space is in danger of becoming militarised, with Britain in the vanguard. "I find this disturbing to say the least," said a local Labour MP, Fabian Hamilton. "It's as if they are saying this is a place in the US and you are foreigners. But ha

Wisconsin governor prank called

Republican is duped by a caller pretending to be one of the rightwing Koch brothers, two of his wealthiest backers The Republican governor at the centre of the union-busting protests in the US has been embarrassed by a prank call that he believed was from one of his billionaire backers. On the recording of the call, which has been released online, the Republican governor of Wisconsin Scott Walker tells a caller impersonating one of the rightwing Koch brothers that he is looking forward to flying to California to celebrate with them once the battle with the unions was won, and jokes about taking a baseball bat to slug Democratic leaders. Walker is under siege in his office in the state capitol building in Madison, Wisconsin, in a backlash against his proposed legislation to remove unions' right to collective bargaining and cut public sector workers' pay. Ian Murphy, who calls in pretending to be David Koch, suggests planting troublemakers among the protesters, who have been peac

As China Rolls Ahead, Fear Follows

As China Rolls Ahead, Fear Follows - China kept economy growing in past couple of years by printing money. Now it's feeling consequences. Inflation in consumer prices, speculative bubble in property. Milk dearer in Shanghai than in New York Agence France-Presse — Getty Images China is looking to restructure its economy away from dependence on exports like textiles. For nearly two years, China’s turbocharged economy has raced ahead with the aid of a huge government stimulus program and aggressive lending by state-run banks. But a growing number of economists now worry that China — the world’s fastest growing economy and a pillar of strength during the global financial crisis — could be stalled next year by soaring inflation, mounting government debt and asset bubbles. Two credit ratings agencies, Moody’s and Fitch Ratings , say China is still poised for growth, yet they have also recently warned about hidden risks in its banking system. Fitch even hinted at the
