A new version of Canada’s Food Guide was announced by Canadian Health Minister Tony Clement on Feb. 5, 2007. The guide has helped Canadians with healthy eating habits since 1942 but was last updated in 1992. It is the Canadian government’s most-requested publication after income tax forms.

Changes to the Food Guide include:

• a first-time recommendation to include a small amount of unsaturated fat in regular diets;
• physical activity to complement healthy eating;
• advice for some people to take vitamin supplements;
• an advisory to limit foods with excess salt, sugar, fat and calories, which is considered an unprecedented caution regarding junk food.

NASA’s Cassini–Huygens spacecraft has discovered evidence for a large-scale saltwater reservoir beneath the icy crust of Saturn’s moon Enceladus. The data came from the spacecraft’s direct analysis of salt-rich ice grains close to the jets ejected from the moon. The study has been published in this week’s edition of the journal Nature.

Data from Cassini’s cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are relatively small and usually low in salt far away from the moon. Closer to the moon’s surface, Cassini found that relatively large grains rich with sodium and potassium dominate the plumes. The salt-rich particles have an “ocean-like” composition and indicate that most, if not all, of the expelled ice and water vapor comes from the evaporation of liquid salt-water. When water freezes, the salt is squeezed out, leaving pure water ice behind.

Cassini’s ultraviolet imaging spectrograph also recently obtained complementary results that support the presence of a subsurface ocean. A team of Cassini researchers led by Candice Hansen of the Planetary Science Institute in Tucson, Arizona, measured gas shooting out of distinct jets originating in the moon’s south polar region at five to eight times the speed of sound, several times faster than previously measured. These observations of distinct jets, from a 2010 flyby, are consistent with results showing a difference in composition of ice grains close to the moon’s surface and those that made it out to the E ring, the outermost ring that gets its material primarily from Enceladean jets. If the plumes emanated from ice, they should have very little salt in them.

“There currently is no plausible way to produce a steady outflow of salt-rich grains from solid ice across all the tiger stripes other than salt water under Enceladus’s icy surface,” said Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

The data suggests a layer of water between the moon’s rocky core and its icy mantle, possibly as deep as about 50 miles (80 kilometers) beneath the surface. As this water washes against the rocks, it dissolves salt compounds and rises through fractures in the overlying ice to form reserves nearer the surface. If the outermost layer cracks open, the decrease in pressure from these reserves to space causes a plume to shoot out. Roughly 400 pounds (200 kilograms) of water vapor is lost every second in the plumes, with smaller amounts being lost as ice grains. The team calculates the water reserves must have large evaporating surfaces, or they would freeze easily and stop the plumes.

“We imagine that between the ice and the ice core there is an ocean of depth and this is somehow connected to the surface reservoir,” added Postberg.

The Cassini mission discovered Enceladus’ water-vapor and ice jets in 2005. In 2009, scientists working with the cosmic dust analyzer examined some sodium salts found in ice grains of Saturn’s E ring but the link to subsurface salt water was not definitive. The new paper analyzes three Enceladus flybys in 2008 and 2009 with the same instrument, focusing on the composition of freshly ejected plume grains. In 2008, Cassini discovered a high “density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected” in geysers erupting from the moon. The icy particles hit the detector target at speeds between 15,000 and 39,000 MPH (23,000 and 63,000 KPH), vaporizing instantly. Electrical fields inside the cosmic dust analyzer separated the various constituents of the impact cloud.

“Enceladus has got warmth, water and organic chemicals, some of the essential building blocks needed for life,” said Dennis Matson in 2008, Cassini project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.

“This finding is a crucial new piece of evidence showing that environmental conditions favorable to the emergence of life can be sustained on icy bodies orbiting gas giant planets,” said Nicolas Altobelli, the European Space Agency’s project scientist for Cassini.

“If there is water in such an unexpected place, it leaves possibility for the rest of the universe,” said Postberg.

The British Food Standards Agency (FSA) has announced a recall of foods containing banned dyes which increase the risk of cancer. The food products were sold at the Tesco, Waitrose, and Somerfield supermarkets.

A Bristol company called “Barts Spices” found the illegal Para Red substance in their Barts Ground Paprika, which was sold in 48g and 46g jars with a “Co-op” label. The batch codes on the affected products are 5032 and 5089 (expiration Dec 2007), and 5075 (expiration February 2007).

Tesco also found that their 130g package of BBQ rice cakes (expiration November and December 2005) contained both Para Red and Sudan I.

“It would be very prudent to assume that it could be a genotoxic carcinogen,” FSA scientific advisers told reporters.

“As a company committed to supplying only the very finest quality food ingredients, we took the immediate decision to withdraw our ground paprika spice from all outlets selling the product and advertised a product recall in the national press,” a Barts Spices spokesman said in a statement.

Sudan I is only authorized for industrial use to colorize petroleum products, such as shoe polish. Para Red and Sudan I are banned under the British Colours in Food Regulations of 1995.

Britain last went through a major food recall in February, when Worcester Sauce was found to contain chili powder dyed with Sudan 1.

News reports are claiming that dolls depicting former Nazi leader Adolf Hitler will go on sale in Ukraine. These reports cite Ukraine’s Zerkalo Nedeli newspaper which reported that a toy manufacturer would release the line of Hitler dolls in the summer.

The 40cm doll will reportedly first be available in Kiev with a £100 (GBP) price tag and comes with a large range of accessories in a presentation box with the dates of Hitler’s birth and death.

Nazis images are illegal in Ukraine, with positive portrayal specifically banned. However, there are allegations that right-wing nationalist politics are gaining strength in the country and that xenophobia and racism are on the rise, including some said to be comparable to that present in Germany under Nazi rule. Fascism and propaganda are also banned.

When the former Soviet Union, including Ukraine, was invaded by Germany under Hitler’s rule 2–3 million Ukrainians were among the casualties, of which 1.5 million were Jews.

Adolf can be dressed in various guises, including “early days Adolf”, which consists of a brown shirt and jodhpurs, and “Wartime Adolf”, which features a grey tunic, black trousers and the Iron Cross medal. The doll also comes with boots and shoes, caps, gloves, full uniforms, cane and belt which can be placed on Hitler, whose arms move, allowing the doll to replicate the famed salute of its real life counterpart.

Also included is a model of Blondi, Hitler’s female German Shepherd, who was exceedingly loyal to Hitler. Hitler poisoned Blondi with cyanide in 1945 at the same time as taking his own life in his bunker at Berlin.

“It is like Barbie. Kids can undress fuhrer, pin on medals and there’s a spare head in the kit to give him a kinder expression on his face. He has glasses that are round, in the manner of pacifist John Lennon,” said one saleswoman. The company, which will release the dolls in Summer, says that if demand is high a range of toys themed on the Third Reich may be released, to include barracks, working models of crematoriums and gas chambers, concentration camps and interior models of the chancellery.

The doll is not set to be released until the summer, but BBC News Online has footage suggesting that some stores are selling the doll already.

London, England — On Wednesday, Wikinews interviewed Duncan Campbell, one of the creators of wheelchair rugby.

((Laura Hale)) You’re Duncan Campbell, and you’re the founder of…

Duncan Campbell: One of the founders of wheelchair rugby.

((Laura Hale)) And you’re from Canada, eh?

Duncan Campbell: Yes, I’m from Canada, eh! (laughter)

((Laura Hale)) Winnipeg?

Duncan Campbell: Winnipeg, Manitoba.

((Laura Hale)) You cheer for — what’s that NHL team?

Duncan Campbell: I cheer for the Jets!

((Laura Hale)) What sort of Canadian are you?

Duncan Campbell: A Winnipeg Jets fan! (laughter)

((Laura Hale)) I don’t know anything about ice hockey. I’m a Chicago Blackhawks fan.

((Hawkeye7)) Twenty five years ago…

Duncan Campbell: Thirty five years ago!

((Laura Hale)) They said twenty five in the stadium…

Duncan Campbell: I know better.

((Hawkeye7)) So it was 1977.

((Laura Hale)) You look very young.

Duncan Campbell: Thank you. We won’t get into how old I am.

((Hawkeye7)) So how did you invent the sport?

Duncan Campbell: I’ve told this story so many times. It was a bit of a fluke in a way, but there were five of us. We were all quadriplegic, that were involved in sport, and at that time we had the Canadian games for the physically disabled. So we were all involved in sports like table tennis or racing or swimming. All individual sports. And the only team sport that was available at that time was basketball, wheelchair basketball. But as quadriplegics, with hand dysfunction, a bit of arm dysfunction, if we played, we rode the bench. We’d never get into the big games or anything like that. So we were actually going to lift weights one night, and the volunteer who helped us couldn’t make it. So we went down to the gym and we started throwing things around, and we tried a few things, and we had a volleyball. We kind of thought: “Oh! This is not bad. This is a lot of fun.” And we came up with the idea in a night. Within one night.

((Hawkeye7)) So all wheelchair rugby players are quadriplegics?

Duncan Campbell: Yes. All wheelchair rugby players have to have a disability of some kind in all four limbs.

((Laura Hale)) When did the classification system for wheelchair rugby kick in?

Duncan Campbell: It kicked in right away because there was already a classification system in place for wheelchair basketball. We knew basketball had a classification system, and we very consciously wanted to make that all people with disabilities who were quadriplegics got to play. So if you make a classification system where the people with the most disability are worth more on the floor, and you create a system where there are only so many points on the floor, then the people with more disability have to play. And what that does is create strategy. It creates a role.

((Hawkeye7)) Was that copied off wheelchair basketball?

Duncan Campbell: To some degree, yes.

((Laura Hale)) I assume you’re barracking for Canada. Have they had any classification issues? That made you

Duncan Campbell: You know, I’m not going to… I can’t get into that in a major way in that there’s always classification issues. And if you ask someone from basketball, there’s classification issues. If you ask someone from swimming… There’s always classification issues. The classifiers have the worst job in the world, because nobody’s ever satisfied with what they do. But they do the best they can. They’re smart. They know what they’re doing. If the system needs to change, the athletes will, in some way, encourage it to change.

((Laura Hale)) Do you think the countries that have better classifiers… as someone with an Australian perspective they’re really good at classification, and don’t get theirs overturned, whereas the Americans by comparison have had a number of classification challenges coming in to these games that they’ve lost. Do you think that having better classifiers makes a team better able to compete at an international level?

Duncan Campbell: What it does is ensures that you practice the right way. Because you know the exact classifications of your players then you’re going to lineups out there that are appropriate and fit the classification. If your classifications are wrong then you may train for six months with a lineup that becomes invalid when that classification. So you want to have good classifiers, and you want to have good classes.

((Laura Hale)) When you started in 1977, I’ve seen pictures of the early wheelchairs. I assume that you were playing in your day chair?

Duncan Campbell: Yes, all the time. And we had no modifications. And day chairs at that time were folding chairs. They were Earjays or Stainless. That’s all the brands there were. The biggest change in the game has been wheelchairs.

((Laura Hale)) When did you retire?

Duncan Campbell: I never retired. Still play. I play locally. I play in the club level all the time.

((Laura Hale)) When did you get your first rugby wheelchair?

Duncan Campbell: Jesus, that’s hard for me to even think about. A long time ago. I would say maybe twenty years ago.

((Laura Hale)) Were you involved in creating a special chair, as Canadians were pushing the boundaries and creating the sport?

Duncan Campbell: To a degree. I think everybody was. Because you wanted the chair that fit you. Because they are all super designed to an individual. Because it allows you to push better, allows you to turn better. Allows you to use your chair in better ways on the court. Like you’ve noticed that the defensive chairs are lower and longer. That’s because the people that are usually in a defensive chair have a higher disability, which means they have less balance. So they sit lower, which means they can use their arms better, and longer so they can put screens out and set ticks for those high point players who are carrying the ball. It’s very much strategic.

((Hawkeye7)) I’d noticed that in wheelchair basketball the low point player actually gets more court time…

Duncan Campbell: …because that allows the high point player to play. And its the same in this game. Although in this game there’s two ways to go. You can go a high-low lineup, which is potentially two high point players and two very low point players, which is what Australia does right now with Ryley Batt and the new kid Chris Bond. They have two high point players, and two 0.5 point players. It makes a very interesting scenario for, say, the US, who use four mid-point players. In that situation, all four players can carry the ball; in the Australian situation, usually only two of them can carry the ball.

((Laura Hale)) Because we know you are going soon, the all-important question: can Canada beat the Australians tonight?

Duncan Campbell: Of course they are. (laughter)

((Laura Hale)) Because Australians love to gamble, what’s your line on Canada?

Duncan Campbell: It’s not a big line! I’m not putting a big line on it! (laughter) I’d say it’s probably 6–5.

((Hawkeye7)) Is your colour commentary for the Canadian broadcast?

Duncan Campbell: That was for the IPC. I did the GB–US game this morning. I do the Sweden–Australia game tomorrow at two. And then I’m doing the US–France game on the last day.

((Laura Hale)) Are you happy with the level of coverage the Canadians are providing your sport?

Duncan Campbell: No.

((Laura Hale)) Thank you for an honest answer.

Duncan Campbell: Paralympic Sports TV is their own entity. They webcast, but they’re not a Canadian entity. Our Canadian television is doing… can I swear?

((Laura Hale)) Yeah! Go ahead!

Duncan Campbell: No! (laughter) They’re only putting on an hour a day. A highlight package, which to me is…

((Hawkeye7)) It’s better than the US.

Duncan Campbell: Yes, I’ve heard it’s better than the US. At the same time, it’s crap. You have here [in Great Britain], they’ve got it on 18 hours a day, and it’s got good viewership. When are we going to learn in North America that viewership is out there for it? How many times do we have to demonstrate it? We had the Paralympics in Vancouver two years ago, the Winter Paralympics, and we had crappy coverage there. There was an actual outburst demand to put the opening ceremonies on TV because they weren’t going to do it. And they had to do it, because everybody complained. So they did it, but they only did it in BC, in our home province, where they were holding it. The closing ceremonies they broadcast nationally because the demand was so high. But they still haven’t changed their attitudes.

((Laura Hale)) I have one last question: what did it mean for you when they had a Canadian flag bearer who was a wheelchair rugby player?

Duncan Campbell: I recruited that guy. It was fantastic. I recruited him. Found him playing hockey. And that guy has put in so much time and effort into the game. He absolutely deserves it. No better player.

((Laura Hale)) Thank you!

((Hawkeye7)) Thank you! Much appreciated.

Wednesday, February 23, 2005A compound in the common daisy-like plant feverfew kills human leukemia stem cells and could form the basis for newer, more effective drugs for the disease.

American researchers at the University of Rochester Medical Center in New York say that it could take months to develop a useable drug from the compound, parthenolide.

However, they are working to do so with chemists at the University of Kentucky who have identified a water-soluble molecule with the same properties. The US National Cancer Institute has also accepted the work into its rapid access program, which aims to speed experimental drugs into human clinical trials.

“This research is a very important step in setting the stage for future development of a new therapy for leukemia,” says Rochester researcher Craig Jordan. “We have proof that we can kill leukemia stem cells with this type of agent, and that is good news.”

Parthenolide appears to target the roots of myeloid leukemia, stem cells, while current treatments including the relatively new drug Gleevec don’t. So, “You’re pulling the weed without getting to the root,” says Jordan.

Used for centuries to fight fevers, inflammation and arthritis, feverfew earned interest from the Rochester researchers after other scientists showed that it could prevent skin cancer in animal models.

So the researchers investigated how a concentrated form of the plant component parthenolide would affect leukemia cells and normal cells.

Comparing the impact of parthenolide to the common chemotherapy drug cytarabine, they found that parthenolide selectively killed leukemia cells while sparing normal cells better.

While the findings suggest that parthenolide is a good starting point for new drugs, people with leukemia aren’t being encouraged to take high doses of feverfew as they could not take enough of the remedy to halt the disease.

The research is reported in the journal Blood.

A record number of complaints, over 600, against the New Zealand restaurant chain Hell Pizza for its advertising campaign using condoms delivered via letterbox have been upheld by the Advertising Standards Authority (ASA). Family First “welcomes heavenly decision from ASA on Hells Pizza.”

Hell Pizza delivered sealed foil condoms in a cardboard box to households nationwide. On the outside of the box were the words: “Our pizza for meat lovers!” and the restaurant logo. The inside of the box included the condom and explicit instructions on how to use it. Hell Pizza delivered 70,000 condoms to households. An additional 100,000 were distributed to health and community groups who the chain said were “very supportive.”

Bob McCoskrie, director of Family First, said: “This is a victory for the protection of families from grubby advertising by companies like Hell’s Pizza, and is also a message to other companies who cross the line of what is decent and acceptable to our community. This is a pizza delivery company taking the moral high ground on sex education and telling parents how to give sex education to their kids, implying that all parents have failed at this, and kids as young as five should be exposed to this type of material.”

S. Nicholas filed a formal complaint and said in the complaint:” Any child can open the box take out these condoms and play with them. These are contraceptive devices, not playthings. The package also gave full instructions ‘how to use the condom’ in case some young person wanted to ‘experiment’! It shows lack of taste and is irresponsible.”

Other complainants said that it is inappropriate to promote food with a condom, the text “meat lovers” was offensive, that it undermined family values, and removed the right for families to teach sex education to their children. Condom use instructions that came with the advertising campaign were unnecessary and unacceptable and that there are health and safety issues if the condom broke during delivery.

The ASA said that three code of ethic rules were broken. They were basic principle 4, advertisements should follow a sense of social responsibility to both the consumers and society; rule 4, advertisements should not contain anything generally offensive and rule 5, advertisements should not contain anything that would cause serious widespread offence.

The agency Cinderella, acting on behalf of Hell Pizza, said that they “most certainly did approach this campaign with a due sense of social responsibility to consumers and society.”

Cinderella said: “From the very beginning, the company’s marketing activities were unconventional and memorable… HELL has built a successful brand by utilizing a limited marketing budget in ways that sought to grab attention and secure significant additional media coverage that would never have been able to be sustained using conventional, paid-for, advertising techniques.”

“LUST and sex are, in our experience, often found not far apart. One generally follows the other. And enjoying great food either before or after is also not such a stretch.”

Replying to the instructions that have to be printed, Cinderella said: “The terms are not really sexually arousing and the suggestion made by one hysterical complainant that they could then go and act out the instructions on the next door child is just not plausible and probably not even physically possible. It borders on insane to believe that this is a credible risk. …there has not been an explosion of sexual assault of children after being exposed to government health warnings.”

The ASA then considered all information given to them by both complainants and the advertiser.

The ASA agreed that the advertisements were in breach of basic principle 4 because: “Unsolicited, unaddressed delivery of a condom to letterboxes to promote a food brand did not meet [the basic principle 4] standard.” The standard “required all advertising to be prepared with a due sense of social responsibility to consumers and society.”

The ASA then reviewed whether or not the advertisement programme had breached rule 4 and rule 5. “The method of distribution was a key factor in considering whether or not the promotion had breached the Rules, taking into account the random context, medium, audience and product. The majority of the Board noted that it was difficult to target specific groups or ages using unaddressed letterbox distribution. In addition, it was concerned that such a method of distribution allowed any member of a household access to the advertising.” The majority of the ASA board did not find the instructions offensive but did agree that it would cause widespread offense. The advertisement programme is in breach of rule 4 and rule 5.

Some of the ASA board said: “…While the promotion had caused offence to some, this was offset by the possibility that the promotion had reached an audience that may not access the safe sex message via other media.”

The ASA decided to uphold the complaints, “complaints were unanimously upheld.”

“Our message to Hell’s Pizza is simple – stay out of the bedroom and get back into the kitchen,” Mr McCoskrie said.
