Save the Spotted Owl! With Mr. Chainsaw and Mrs. Shotgun…

Yes, you did read the title correctly. The U.S. Fish and Wildlife Service (FWS) have now turned their attentions to the plight of the Northern spotted owl, which resides in the woods and forests of the Pacific Northwest. Current proposals include shooting competing owls and chopping down trees with cuddly old Mr. Chainsaw.

The proposals come in response to the figures showing that since the owl was made an endangered species in 1990 spotted owl numbers have decreased by an average of 3% each year. Ok, now this is something which clearly needs to be looked at, especially since the rival barred owls invaded its ancestral territories.

Northern Spotted Owl

These proposals have emerged from a report the FWS conducted into the plight of the owl in the summer of 2011. In this case, the FWS have submitted some sensible proposals like the idea to increase the owl’s protected habitat by around 2.2 million hectares.

However, what has caused some controversy is the battle over deforestation as FWS director Daniel Ashe suggested that fire-prone forests should be logged to protect the landscape. The problem with this is that exactly how fire-prone does a forest have to be to be logged? Most forests are technically prone to fire, but if we have a forest which has stood for a generation without any problems then should we be logging that? Of course we shouldn’t.

Overall, the idea of logging fire-prone forests in the vain hope that it will help encourage the growth of the spotted owl is a slippery slope as taking the decision to cut down trees which take years and years to grow should not be taken lightly.

Also, let’s take a look at a pertinent point made by Ecologist Dominick DellaSala, director of the Geos Institute in Ashland, Oregon, who made the interesting point that this proposal by the FWS is untested. This proposal has never had any studies conducted, large or small, so are we just going to chop down the trees and pray it works? That’s not science, that’s idiocy.

The other proposal was to simply remove the barred owls from the territories. This would be a sensible decision if the owls are having a negative impact on the spotted owls, but are they really? Even Daniel Ashe of the FWS conceded that it would be at least a decade into the experiment before this could be discovered at all, and this is what makes you wonder whether it’s really a good idea at all.

So they want to either shoot or relocate the barred owls to boost the spotted owl population, despite the fact that they don’t know if this will help at all? Essentially, they are saying let’s give another species of owl a good kicking as an experiment to see if it will help. That’s not right at all. Relocate them, maybe, but don’t shoot them.

The question they should also be asking is why are the Barred owls there? Why have they moved out of their own territories? If the answer is overpopulation due to the fact that they have grown too much then, yes, the population may need to be culled. But if the population has been reduced because you destroyed their homes, then that’s your fault and you should be removing the logging companies and creating an area where they can flourish without having to damage other species.

The public do have 90 days to submit their comments, but what do you think should be done when an endangered species’ territory has been invaded by another species which has become displaced somehow?

Is Anti-Smoking Based on Science or Morality?

Tobacco smoking is currently seen by many as the scourge of society, an action of those wanting to slowly kill themselves. It is common perception that this idea is based solely on scientific evidence that has accumulated over the past 60 years. Yet the truth is, smoking has always attracted the wrath of purists. In the past, ‘public health’ measures were not enacted because of scientific evidence, but a sense of morality – alcohol was condemned and labelled a sinful activity because of moral sensitivity, and the same was true of tobacco. So the question is, is the attack on smoking today once again borne of ethical reasoning, or scientific rigour?

 

When Christopher Columbus reached Cuba in 1492 with Rodrigo de Jerez and Luis de Torres, his two men experimented with smoking the tobacco pipe; Columbus himself not only refrained but spoke against it, referring to Rodrigo and Luis as sinking to the level of “savages” for smoking. When they packed tobacco on their boat and returned to Europe, there was an immediate divide between those who loved it and those who hated it, even inspiring King James I to write ‘A Counter Blaste to Tobacco’.

 

In the 1600s parts of the world saw people actively punishing smokers. First-time ‘offenders’ in Russia were subjected to being whipped and having their noses slit before being sent to Siberia. If they were caught a second time, they were punished by death. Sultan Murad IV of Turkey castrated smokers, and 18 a day were executed. In China, smokers were decapitated.

 

Such activities did not spread to the UK or USA, but other restrictions existed. In 1900, Tennessee, North Dakota, Washington and Iowa banned the sale of cigarettes by law, and by the following year 43 American states were strongly opposed to smoking. In 1904 a woman in New York was sentenced to prison for smoking in the presence of her children, and a policeman arrested a woman smoking in her car, stating “You can’t do that on Fifth Avenue.” In 1907, businesses refused to employ smokers.

 

By 1917 the anti-smoking feelings were still strong, and the primary focus was on using children to stop people smoking. Doctors would tell smokers they would suffer from blindness, tuberculosis or “tobacco heart”. Like today, insurance companies and surgeons would enquire if their customers or patients smoked. The August 1917 issue of magazine ‘The Instructor’ was labelled “the annual anti-tobacco issue” and featured cartoons to demonise smoking, as well as articles stating: “One puff does not destroy the brain or heart; but it leaves a stain…until finally the brain loses its normality, and the victim is taken to the hospital for the insane or laid in a grave. One puff did not paralyse the young man in the wheel chair; but the many puffs that came as a result of the first puff, did.”

 

That run of anti-smoking lasted until 1927, in America at least, but none of our science of today had been collected by then, rather it was all based on a moral principle. Germany was producing its own anti-smoking campaign around that time, with the famous “The German woman does not smoke” posters, as well as public smoking bans. The 1950s was the decade that saw the creation of the now-famous studies by Sir Richard Doll linking smoking to lung cancer, and in this time were other researchers like Ernst Wynder, described as a fanatical anti-smoker. By focusing on smoking as a sole factor in a time when it had yet to be implicated in disease was perhaps a tip of the hat that the researchers wanted to find an association, as so many scientists strived to do at this moment in history. In light of the findings, it was mentioned that 10% of smokers may contract lung cancer. That figure has been dropped in more recent decades although it still remains true.

 

Things progressed again in the 1970s with what has become known as the Godber Blueprint. Sir George Godber was a WHO representative who spoke openly of the “elimination of cigarette smoking” with comments such as “Need there really be any difficulty about prohibiting smoking in more public places? The nicotine addicts would be petulant for a while, but why should we accord them any right to make the innocent suffer?” Godber laid out a plan to achieve that goal, much of which has come into effect, such as “major health agencies [should] join forces to create and produce anti-smoking material for mass media” and he said the following should happen: elimination of smoking cigarettes; include quit-smoking assistance in health insurance; create “a social environment in which smoking is unacceptable”, raise tobacco prices enough to discourage sales; ban all forms of tobacco advertising; and create committees of sophisticated politicians in every country to help pursue stated goals. Almost 20 years before the EPA’s report that second-hand smoke poses a threat to non-smokers, Godber was creating plans to convince people of that very thing.

 

With regards to second-hand smoke and the question of ‘morality or science?’, about 85% of the studies on secondhand smoke and lung cancer failed to find a significant relationship between the two. Of the remaining 15% most indicated a statistical positive relationship while some actually indicated a statistical negative, or protective, relationship.  The studies of course were all statistical epidemiology: not actual findings of cause and effect. Only 15% find an associated risk, and the average relative risk of those is only 1.17, which is categorised as statistically insignificant. Of the 85%, most are kept out of sight, the most famous probably being the study conducted by the WHO, the largest study performed on second-hand smoke and which was hidden by the organisation because its findings showed no ill-effect of secondhand smoke. Enstrom and Kabat also conducted a large study, for 39 years, into passive smoking. It was commissioned by the American Cancer Society and was funded by the Tobacco-Related Disease Research Program. When the preliminary data arrived and showed no harm was posed from passive smoking, the funding was pulled. This led the researchers no choice but to accept funding from the tobacco industry-funded Center for Indoor Air Research, although the results remain unchanged from what was discovered when the TRPRP funded it.

 

Recently there have been suggestions or enacting of outdoor bans, with Milton Keynes almost having one and New York establishing one, despite no evidence to suggest that they benefit health of non-smokers. Indeed, anti-smokers today openly talk of keeping smokers out of sight and “denormalising smoking”. Although the difference today with the past is that there are now many vested interests with financial gains to be sought from the prohibition of tobacco, the similarity remains that much of the hysteria is based on a moral disagreement with the act. If the science is lacking, as it is on passive smoking, but bans are still in place and studies showing ‘undesirable’ results are hidden while those who do not agree with the literature are to be accused of being in the pocket of Big Tobacco, the scientific credibility is thrown into disrepute, and we are left wondering if those behind the numbers harbour similar feelings to Columbus himself.

 

 

The OxyContin Cha Cha

This is a guest post by Andrew Phillips

The dangers of OxyContin were known in the late 1990s and between the years 1999 and 2003 there had been between a 4 and 5 fold increase in deaths where OxyContin had been detected in the blood stream. By now many people are aware of the fact that the government will be taking Oxycontin out of pharmacies across the country. Ontario will be delisting the painkiller as well. However, down in the Maritimes no plan is in place to fund either OxyContin or its replacement OxyNeo. Saskatchewan is also not planning on funding OxyContin either.

Discussions to delist the drug started about the time Purdue Pharma sent notices that the company was replacing OxyContin with OxyNEO, which was approved by Health Canada on Aug. 22, 2011. But OxyNeo is exactly the same thing as OxyContin; in fact the only difference appears it’ll be harder to crush and snort; same stuff different name. But why is it being taken off the market now when what it has been doing has been known for so long? Easy – OxyContin is about to go off patent in 2013.

As to Health Canada I suggest you read that article especially the section about conflict of interest and the fast-tracking of drug approval and question the approval of OxyNEO. But perhaps the worst aspect of this partnership is Health Canada’s failure to enforce the rules against Direct to Consumer Advertising of prescription drugs in Canada, ads which use fear to drive patients into doctors’ offices to demand the most expensive new drugs that may or may not help them.

To understand the inherent danger of DTCA this article goes in depth into how it works. Another interesting thing is recently the Supreme Court ruled that ISPs aren’t bound by the Broadcast Act with one of the countries biggest ISPs – Bellmedia – now owning CTV, CTV2, and many radio and speciality channels. Will they use this as an end around to run even more DTCA drug ads in Canada? Ads for Champix and Gardasil are showing up on Canadian TV now and it is possible that we can expect to see more DTCA in the near future.

An interesting sidebar to this is Health Canada is in charge of the Consumer Product Protect Act which, considering what they’re doing – or not doing – now, makes you wonder what is the real reason for it in the first place. You can read about it here and here. Quite frankly it appears to be another euphemistically named law, much like the Protecting Children from Internet Predators Act that Vic Toews, it now appears they didn’t bother to read too carefully that actually curtails civil liberties and property rights. So while they’re are working on the “Surveillance Bill” they should pull that one out as well.

Of all the news articles in Canada not one of them has mentioned the going off patent angle. Not one of them has mentioned just how curious it is that while one is being pulled early a replacement is already available. The farcical assertion that drug addicts will be stopped by a pill that is a little tougher to crack is negated by new extraction techniques that are already being discussed by addicts and this little nugget goes along way to explaining the timing, “…the company is positioning itself to avoid having its product deemed interchangeable with lower cost alternatives that will be brought to market once OxyContin® loses its exclusive patent”. Ultimately that new extraction technique might just mean buying a bigger hammer. They’re drug addicts, they’re not stupid.

Iron-Spiked Bacteriophages

It’s been known by scientists and university students alike that a type of virus called a bacteriophage attacks bacteria by drilling through the outer membrane of the bacterium. The virus then runs wild and multiplies until the unfortunate little bacterium explodes in a spectacular cellular fireworks display. But what scientists have never been able to discover is just how they get inside bacteria to begin with – until now.

Bacteriophage

Petr Leiman, a biophysicist at the École Polytechnique Fédérale de Lausanne in Switzerland who led the team of scientists, and who will publish his findings in Structure said that they had already anticipated that a special kind of protein was making the initial opening. However, the problem was that they couldn’t see the end of the tip to determine what it was.

The team of scientists, at their Swiss base, decided to reverse engineer the tips to try and find out what they were made of. Their test subjects were the bacteriophages P2 and Φ92; for those people who don’t know the book off by heart, they typically attack the e-coli bacteria and the bacteria which cause salmonella. The P2 gene for its bacterium puncturing capabilities was already well-known to scientists, and after some searching the gene for Φ92 was also found.

The proteins in these genes were then grown and isolated, before been turned into crystals. This allowed scientists to use the x-ray crystallography technique to bombard the crystals with x-rays in order to bring up an image of the structure. This went well, but one problem still remained. The end of the structure, the part they were looking for, didn’t show up.

Undeterred, though, the genes were reengineered to only produce the invisible part of the structure. After carrying this out, it was then found that the end of the spike was a single iron atom connected by six amino acids.

Originally, it was thought that bacteriophages had help from elsewhere to puncture the outer membranes of the bacterium, but clearly they don’t need any help at all as they have a super-mini iron spike instead.

But what’s the point of all this? Well, the answer to this is that if scientists can use the viruses to find weaknesses in bacteria then it could lead to a number of new ultra-powerful medicines. However, let’s be honest, even if the scientists do create the medicines, we won’t see any of these new medicines in Britain anytime soon as this country has a history of withholding a number of these new medicines due to the fact that it would cost more money.

Alcohol on the Big Screen Encourages Binge Drinking (apparently)

It was suggested in a US study, published in  online journal BMJ Open, on the 21st of February that actors who drink on the big screen are encouraging experimentation with alcohol amongst children.

The study says that the stars act as successful role models who encourage children to drink. The thinking goes that if a child looks at a famous actor and they are drinking heavily then it’s ok because they have already made themselves famous and they don’t look like they are suffering from health problems.

This study was unprecedented in the number of test subjects as it randomly selected more than 6,500 American children between the ages of 10 and 14 for a phone interview, and then another three additional interviews in the next two years. Obviously, they would have had an issue getting through to some children as their parents were too drunk to answer the phone at the time (hint hint).

The questions asked ranged from which movies they had seen, whether they currently drank or had drunk alcohol in the past, and whether they owned any merchandise which had any alcoholic brands attached to it. Of course, they were also asked about their school and home lives in general too.

Child Watching a Film

The films used to compare the implied and actual consumption of alcohol by researchers were taken from films which had grossed at least $15,000,000 when the interviews had first started. After that the researchers then used the character’s implied and actual consumption and purchases of alcohol to find out the results.

The researchers found that youngsters, on average, had been exposed to roughly four to eight hours of viewing involving alcohol from the most popular films on the market. Other items of interest from the survey also showed that during the two year study, the number of respondents who admitted they had started drinking alcohol had risen from 11% at the start to 25% by the end of it.

Furthermore, the number of binge drinkers tripled from 4% to 13% by the end of the study; binge drinking, as outlined in this study, is having at least five drinks in a row.

Ok, these are startling figures as they do eclipse the figures gained from having bad parents, having lots of money, and a rebellious teen spirit. But can’t we see one fatal flaw in this experiment? How exactly do you isolate this one specific factor?

How are you going to isolate this one specific factor, which is alcohol in movies, without putting the kids in a room on their own? The answer is you can’t. So how can these figures really be that reliable? The answer is they can’t as they are also going to be exposed to a number of different factors at the same time; such as peer pressure, rebellion, and coming into money.

And let’s go further and make the point that a phone survey is just a phone survey. None of the test subjects were ever met in person so how can you be sure they are telling the truth? And when someone talks about alcohol we all know that people significantly underestimate how much they really drink, don’t we?

But let’s look at children. Children are always being told how bad it is to drink underage, which is against the law. So realistically how many of them are going to readily admit it? How do you know that some of the test subjects are not claiming they don’t drink when they really do? If they did this would further support the study’s conclusion, but it’s important just to bring up the point anyway.

Nonetheless, what we can expect from the findings of this study is that they will either slink away from the publix gaze into the darkness after a week or so or it will cause panic throughout America and parents will be covering their children’s eyes and protesting for the removal of all alcohol from films. Sooner or later we are going to end up living in a world where alcohol can’t be seen on TV, can’t be talked about on the radio, can’t have colourful packaging, and can only be drunk within the basement of one’s own home, when the child is at school.

So it’s either going to be a giant overreaction or completely ignored, what do you think?

Scientists Look to Create an Artificial Hamburger. Yum Yum?

We have now reached a new plane of science as the Dutch have managed to begin creating an artificial hamburger.

Dutch scientists are producing strips of muscle tissue using stem cells, as we speak, in order to create the first hamburger grown in a lab. The estimated end to this project is later this year, but don’t be expecting them in shops soon as the cost of this project is a gigantic £200,000.

But why are they wasting their time trying to create a hamburger? No, it’s not to challenge the global fastcrap shack that is McDonald’s, but it’s to help with the problem of an increasingly large and hungry population. And you never know, it may even prove to be an alternative to killing animals.

Professor Mark Post, while at a major science meeting in Canada. touted the possibility of introducing synthetic meat into wider society by saying that the concept could eventually decrease the footprint of meat on the environment by an incredible 60%.

Professor Post, who is running the experiment with his group at Maastricht University in the Netherlands, is carrying out the experiment by growing pieces of off-white muscle which are 1cm in width, 1mm thick, and roughly 2cm long in small bowls.

Artificial Hamburger
Is this the future of meat?

It’s expected that the strips will then be soaked with fat, which has also been artificially grown, and blood to grow a hamburger. The hamburger is expected to be completed by autumn of 2012.

The professor also commented that he was attempting to get Heston Blumenthal, the celebrity chef, to cook it for him. But he did say that the burger will taste quite bland as flavour is not really the priority at the moment.

Despite the high price, Professor Post did claim that he was confident that as production lines are sorted out the cost would come down. So it’s possible that synthetic meat could become a resource of the future. And this is incredibly timely as estimates say that the world’s food production will need to double within the next half-century in order to keep up with demand.

Professor Sean Smukler of the University of British Columbia also stressed the importance of this experiment as he claims that farmers will find it particularly difficult to keep up with demand as the amount of farmable land on the planet has been reduced dramatically.

At the moment the future looks bright when it comes to synthetic meat, as Professor Post confidently asserts that it will become more efficient than meat produced in a natural way. Currently there is an efficiency rate of 15% when it comes to producing natural meat, and synthetic meat is aiming for 50%.

The President of Earthsave Canada, David Steele, wasn’t so enthusiastic about the project, though. He claimed that instead of creating synthetic meat, which could be unhealthy due to the number of chemicals required to stop it from rotting, people could just eat less meat.

Now, while this would be a viable option in an ideal world, we have to remember one thing: most people couldn’t care less about the problems of the world unless it’s having a direct effect on them. It’s harsh, but people are generally unwilling to compromise on their own quality and luxury unless the problem is shoved directly in their faces.

And all of this means that the Dutch could be on to a winner here. The Germans may have had the Hamburger named after one of their cities, but it looks like their cultural archrivals have revolutionised it.
