Rice prices jumped 30 per cent to an all-time high on Thursday, raising fears of fresh outbreaks of social unrest across Asia where the grain is a staple food for more than 2.5bn people.

The increase came after Egypt, a leading exporter, imposed a formal ban on selling rice abroad to keep local prices down, and the Philippines announced plans for a major purchase of the grain in the international market to boost supplies. Global rice stocks are at their lowest since 1976.

Forty years after Democratic rising star Robert F. Kennedy was killed at a Los Angeles hotel during his presidential run, new evidence suggests the man serving a life sentence for his murder did not fire the shots that killed the charismatic senator.

Forensic scientists met at a conference in Connecticut this week to discuss their independent findings that cast serious doubt on the Kennedy assassination. Sirhan Sirhan is serving a life sentence in Kennedy’s death, but the conference presenters argue he could not have fired the fatal shot that killed Kennedy.

A chunk of Antarctic ice about seven times the size of Manhattan suddenly collapsed, putting an even greater portion of glacial ice at risk, scientists said Tuesday.

Satellite images show the runaway disintegration of a 160-square-mile chunk in western Antarctica, which started Feb. 28. It was the edge of the Wilkins ice shelf and has been there for hundreds, maybe 1,500 years.

This is the result of global warming, said British Antarctic Survey scientist David Vaughan.

With little-noticed procedural and policy moves over several years, Bush administration officials have made it substantially more difficult to designate domestic animals and plants for protection under the Endangered Species Act.

Controversies have occasionally flared over Interior Department officials who regularly overruled rank-and-file agency scientists’ recommendations to list new species, but internal documents also suggest that pervasive bureaucratic obstacles were erected to limit the number of species protected under one of the nation’s best-known environmental laws.

Though the 9/11 Report has sold over 1.5 million copies, many more millions are just not buying the 9/11 Commissions findings, and like the critics of the Warren Commission – for good reason.

Don’t take my word for it; polls from Zogby, Scripps-Howard, CBS and others tell the story. On this count we know Zelikow failed. It’s where he succeeded that is of concern to commission critic and New York Times reporter Philip Shenon, especially relative to the Commission’s mandate to produce “a full accounting of the facts and circumstances” surrounding the 9/11 attacks.
