From the newscientist:
Rice bran – a so-called “superfood” – might contain dangerous amounts of a natural poison.
A new study suggests that rice bran, the shavings left over after brown rice is polished to produce white rice grains, contains “inappropriate” levels of arsenic. Andrew Meharg at the University of Aberdeen, UK, and colleagues found that the levels of arsenic in rice bran products available on the internet and used in food-aid programmes funded by the US government would be illegal in China – the only country in the world to have standards for how much arsenic is permissible in food.
Meharg’s team are calling on the European Union and the US to follow China’s example and update food standards for arsenic.
Arsenic is a natural carcinogen, present in drinking water around the world including in Australia, the US and many developing countries.
In previous work, Meharg has shown that brown rice contains more arsenic than polished white rice (Environmental Science and Technology, DOI: 10.1021/es702212p).
Nutritional drink
In the new study, Meharg and colleagues purchased brown rice from China and Bangladesh and polished part of it in the same way that it would be to produce commercial white rice. They found that 1 kilogramme of brown rice contained on average 0.76 mg of arsenic in its toxic inorganic form. The rice also contained some non-toxic, organic arsenic. The polished white rice grains contained 0.56 mg inorganic arsenic per kg, whereas the rice bran contained 3.3 mg per kg on average.
On the surface, this appears to be good news: the bran shavings are usually discarded except in Japan, where they are used in traditional pickling recipes. But in recent years a number of rice-bran products have come onto US and European markets, mainly targeted at health-food consumers. They are labelled “superfoods”: the bran is high in antioxidants, vitamins, mineral nutrients and fibre. Producers say it is the largest wasted agricultural food resource on the planet, with 60 million metric tonnes of it discarded worldwide each year.
Some companies have produced a powdered version with a long shelf life at room temperature. Mixed with water, these “rice-bran solubles” make a nutritional drink and have been distributed as food aid to malnourished children in Malawi, Guatemala, Nicaragua and El Salvador. There are plans to further expand the aid programmes in Latin America, India and the Caribbean.
Meharg and his colleagues purchased nine commercial rice-bran products online, including rice-bran solubles from NutraCea, a company that participates in food-aid programmes, and analysed their arsenic content. The products contained between 0.48 mg/kg and 1.16 mg/kg of inorganic arsenic. China recently updated its standards, and set the limit to 0.15 mg of inorganic arsenic per kg of food.
Risk analysis
“The arsenic concentrations reported are worrisome, but the risk assessment is complex,” says Philippe Grandjean, professor of environmental health at Harvard University’s School of Public Health.
Indeed, “safe” standards for arsenic intake are controversial. The risk of skin, lung, bladder and kidney cancer increases proportionally with arsenic intake, which has lead toxicologists to the conclusion that there is no “safe” limit. But risks must be weighed against the benefits gained from drinking water and eating certain foods that contain the poison.
NutraCea has carried out a pilot project distributing their rice-bran solubles to 67,000 pre-school children in Guatemala. They monitored the nutritional state of 150 children. Whereas at the beginning of the trial, 37% were deemed malnourished, that dropped to 5% after taking 15 g of the rice bran 5 days a week for 6 months. The project was funded by the US Agency for International Development USAID and the Christian Children’s Fund.
Marie Vahter, an environmental toxicologist at the Karolinska Institute in Sweden who has done extensive studies on the health effects of arsenic believes the nutritional benefits do not necessarily outweigh the risks, given the availability of other supplements. “Recent reports indicate increased fetal and infant mortality due to fairly low-level arsenic exposure via drinking water,” says Vahter. Arsenic also impairs brain development and impairs the body’s ability to repair DNA.
Unwanted substances
“Rice-bran solubles are not the only way of getting nutrients to malnourished children,” argues Meharg. “If aid agencies want to go down the bran solubles route why not wheat, oat or barely bran solubles. All these crops have ten times less total arsenic than rice and are just as nutrient rich.”
“One would expect dietary supplements to be virtually free of unwanted substances like arsenic, especially when aimed at children, who are particularly vulnerable to arsenic,” says Grandjean.
Drinking water limits on arsenic levels are more widespread than food limits, despite animal studies showing that the body does not distinguish between arsenic derived from food and from drink. Water limits tend to be based on the World Health Organization’s “provisional” guideline limit of 0.01 mg of arsenic per litre of drinking water – although the WHO itself admits that “based on health criteria” the guideline would be less than this. It says the value is restricted by measurement limitations, hence its provisional nature.
According to China’s standards, all of the rice-bran products tested by Meharg would be illegal. According to the UK’s 50-year-old standards, two of the nine products are safe – yet all can be purchased online in the UK. The US has no standards for arsenic levels in food, and has a limit of 0.01 mg/l in drinking water.
“We totally agree with the overall message that it is important to set standards for inorganic arsenic in our food,” comments Walter Goessler, an arsenic expert at the Karl-Franzens University in Austria.
“Rice-bran solubles are being produced by commercial companies who profit from this commodity,” says Meharg.
At the time of going to publication, NutraCea had not replied to New Scientist’s request for comment.

By general consensus, Planet Earth
(The complete series) has been deemed quite simply the greatest nature/wildlife series ever produced. Following the success of The Blue Planet: Sea of Life, this astonishing 11-part BBC series is brilliantly narrated by Sir David Attenborough. Each 50-minute episode covers a specific geographical region and/or wildlife habitat (mountains, caves, deserts, shallow seas, seasonal forests, etc.) until the entire planet has been magnificently represented by the most astonishing sights and sounds you’ll ever experience from the comforts of your living room.
The premiere episode, “From Pole to Pole,” serves as a primer for things to come, placing the entire series in proper context and giving a general overview of what to expect from each individual episode. Without being overtly political, the series maintains a consistent and subtle emphasis on the urgent need for ongoing conservation, best illustrated by the plight of polar bears whose very behavior is changing (to accommodate life-threatening changes in their fast-melting habitat) in the wake of global warming–a phenomenon that this series appropriately presents as scientific fact.
With this harsh reality as subtext, the series proceeds to accentuate the positive, delivering a seemingly endless variety of natural wonders, from the spectacular mating displays of New Guinea’s various birds of paradise to a rare encounter with Siberia’s nearly-extinct Amur Leopards, of which only 30 remain in the wild.
With so many of Earth’s natural wonders on display, it’s only fitting that the final DVD in this 5-disc set is devoted to Planet Earth: The Future, a separate 3-part series in which a global array of experts is assembled to discuss issues of conservation, protection of delicate ecosystems, and the socio-economic benefits of understanding nature as a commodity that returns trillions of dollars in value at no cost to Earth’s human population.
At a time when the multiple threats of global warming should be obvious to all, let’s give Sir David the last word, from the closing of Planet Earth’s final episode: “We can now destroy or we can cherish–the choice is ours.”

From pcworld:
“Travelers beware: U.S. agents now have the authority to seize and retain laptops indefinitely, according to a new policy detailed in documents issued by the U.S. Department of Homeland Security.
As part of border search policy, government agents are now authorized to seize electronic devices and inspect documents in them, the document states. The electronic devices might include laptops, cell phones, portable music players or storage devices such as portable hard drives.
Agents with U.S. Customs and Border Protection will also be allowed to translate and share documents with other government agencies.
The DHS document, issued July 16, appears to state publicly a policy that has already existed. Laptops and electronic devices have been subject to search in the past, and travelers have reported not getting their devices back. The policy has drawn strong criticism from lawmakers and nonprofit groups, who charged that the searches were invasive and a violation of an individual’s privacy rights. Computers contain a vast amount of private information about family, finances and health, which could be easily copied and stored in government databases, the Electronic Frontier Foundation has complained.
The policy document states that being able to examine documents and electronic devices is crucial for “detecting information concerning terrorism, narcotics smuggling … contraband including child pornography, and … other import or export control laws.”
The new DHS policies allow customs agents to analyze the contents of laptops without any suspicion of wrongdoing, U.S. Senator Russ Feingold said in a statement.
“The policies that have been disclosed are truly alarming,” Feingold wrote.
The policy could blur the distinction between “search” and “seizure,” which could also allow DHS officials to steal personal documents from laptops it has retained, Feingold wrote.” [source]

From the iht:
“Governor Arnold Schwarzenegger of California signed a bill banning trans fats in restaurant food, making California the first U.S. state to ban the use of the cooking oils linked to artery-clogging cholesterol.
The new law, modeled after a ban implemented in New York City, prohibits the use of partially hydrogenated oils, which contain trans fats, by the state’s 87,000 restaurants beginning in 2010 and in all baked goods sold in the state starting in 2011.
Trans fats, found in processed and fried food, candies and cookies, are vegetable oils that are treated with hydrogen to extend the shelf life of products. The oils have been linked to LDL cholesterol that clogs the arteries. New York began a ban on trans fats in all restaurants in December 2006.
“Consuming trans fat is linked to coronary heart disease, and today we are taking a strong step toward creating a healthier future for California,” Schwarzenegger said in a statement.
Diets high in trans fats increase the risk of heart disease, obesity and diabetes, according the U.S. Food and Drug Administration’s Web site.
Restaurant companies including McDonald’s and KFC already use cooking oils in the U.S. that are free of trans fats.”

From Paul Craig Roberts at Counterpunch:
A Totally Lawless Regime
Think about this question: In the 21st century what regime is more lawless than the Bush Regime?
Everyone is entitled to his own answer. The only answer I can come up with is the Zimbabwe regime of Robert Mugabe. Voted out of power in the last election, the great man hasn’t left. Zimbabweans are going to have to vote again, and the great man has said that any vote that is not for him will be cancelled by a bullet.
Does anyone remember how determined the British and the Americans and everyone else was to turn Rhodesia over to Mugabe in order to save Rhodesia from the evil Ian Smith? What a fool everyone was.
But before we laugh at those fools, we had best laugh at ourselves, or cry.
It is now an incontrovertible fact, known all over the world, that George W. Bush and his regime lied through their teeth in order to launch wars of aggression against Afghanistan and Iraq, and that the Bush regime is doing the same thing again in hopes of launching an attack on Iran.
There have been a number of memoirs from high ranking Bush appointees who cannot stand all the lies. Bush’s first Secretary of the Treasury, Paul O’Neill, told us that an invasion of Iraq was on the agenda prior to 9/11. There is the leaked Downing Street Memo in which the head of British Intelligence told the British Prime Minister and his cabinet that the Americans have decided to attack Iraq and are creating the “intelligence” to justify the attack.
And now we have the White House’s own spokesman from 2003-2006, Scot McClellen, ratifying what we all already knew, that President Bush deceived us and led us into war based entirely on lies and fabrications, and that he, Scott McClellen, was deceived into issuing a false public denial that top Cheney aide Scooter Libby and White House operative Karl Rove were involved in committing a felony under US law by revealing the identity of a covert CIA operative, Valerie Plame.
As a consequence of Bush’s lies, there are a million dead Iraqis, mostly women and children, and four million displaced Iraqis, 4,100 dead American soldiers and tens of thousands of seriously wounded. No one knows how many dead in Afghanistan. And there is the ongoing Israeli slaughter of Palestinians and Lebanese that has fallen under the rubric of the “war on terror.”
The only ones pleased with these wars are the American neoconservatives, the Israeli right-wing, the US corporate military-security complex, and Osama bin Laden.
The Bush regime has created enormous hatred and disrespect for the United States. A recent world wide poll found that George W. Bush ranks at the bottom of world leaders as one of the least trusted along with US Pakistani puppet Musharraf and the Iranian president, Ahmadinejad, who has the disadvantage of being the victim of demonization by the US and European corporate-controlled media, which serves as ministries of propaganda for the governments that control their broadcast licenses. The American and European media lie for their living.
The two leaders with the highest approval rating are UN Secretary General Ban Ki-Moon and Russian President Vladimir Putin.
So, the old adversary, Russia, now has a more respected leader than the “leader” of the Great Free Nation, a Great Free Nation that has sat on its hands while its “leader” destroyed America’s civil liberties, America’s reputation, the jobs of Americans, and committed the US to a course of war crimes punishable by the International Criminal Court at the Hague.
A number of readers took issue with my recent column, “Elect Obama or Fall Into Tyranny.” Echoing former Alabama Governor George Wallace, readers said Obama would make no difference. But that is what I wrote.
My point was not that Obama would make any difference, as he has put himself and his administration into the hands of Wall Street and the Israel Lobby. I said that the American people could make a difference by rejecting the Republicans, as it was the only accountability that the Republicans were likely to suffer.
If Americans return a Republican regime, Americans will validate the right of the president to violate with impunity US and international law. Americans will validate the use by the president of the United States of deception and lies in order to initiate wars of aggression, aggression that is a war crime under the Nuremburg standard established by the US. Americans will validate the infringement of US civil liberties in the name of “safety” and “national security.” Americans will disembowel the US Constitution and leave themselves at the total mercy of the government.
Reelecting Republicans means the end of the United States as a land of liberty.
I am sympathetic to the argument that we, as a country of liberty, are near our end regardless. Look at the Democrats. Today, June 20, the House of Representatives, which the voters gave to the Democrats in the 2006 congressional elections in order to end the pointless barbarity that the US has brought to Iraq, voted the largest war-spending bill ever. The “antiwar” Democrats completely collapsed, giving the warmonger Brownshirt Republican regime everything it wanted.
The House Democrats, led by “impeachment-is-off-the-table” Nancy Pelosi, added to the Democratic Party’s shame by passing today, June 20, a bill that shields from punishment the criminal Bush regime and the telecommunications corporations that the Bush regime coerced into committing felonies under US law by cooperating in Bush’s illegal spying on American citizens.
The great hope of the Founding Fathers, the people’s house, the House of Representatives, has passed an illegal and unconstitutional retroactive law making acts legal which were illegal when they were committed.
If a Democratic House of Representatives will pass a retroactive law in order to legalize the criminal violations of a Republican regime, the same House will pass a retroactive law making illegal what you did legally yesterday. No one is any longer safe in America. By abandoning the US Constitution, Republicans and Democrats have made America as potentially unsafe as Zimbabwe for anyone who takes exception to the government.
The total collapse of the Democratic Party and the House of Representatives signals the end of liberty and democracy in America. Henceforth, led by the Republican Federalist Society, we will gravitate toward the beautiful regime of “energy in the executive” that has been achieved in Zimbabwe by Robert Mugabe.
