Me and my Soapbox: Thoughts on the Santa Cruz Biotech case


If you work with antibodies, you’ve probably heard about Santa Cruz Biotech (SBC) and hence you’re probably aware by now of the storm that is carrying its name right now related to USDA violations of animal welfare. What you might not be aware of is that the company has been under investigation for over 5 years now. The first inspection pointing at problems with “veterinary care, personnel qualifications, and primary enclosures” of the animals used by the company to produce their antibodies took place back in February, 2011. 

Now, independent on your experience with the company (personally I find that their antibodies are very hit or miss and prefer to work with other companies), this situation is utterly wrong from several points of view. I will not deal with the policy violations, because I don’t have enough background on it, but I would like to discuss the animal welfare part.

As a researcher, I know that certain experiments can only be done in animal models, ranging from roundworms, to flies and up to primates. While a lot of questions can be answered in petri dishes or even with the appropriate software, there’s still a panoply of studies that would not yield the proper answer unless their hypothesis is challenged in vivo, and that’s when animal models come to play.

In the case of antibody production, there is always the possibility of recombinant antibodies which uses different organisms (like yeast) to produce the antibody, often called monoclonal antibodies. Both monoclonal and polyclonal (those produced in animals) have their advantages and disadvantages depending on the application, but at the end of the day, you might not necessarily replace one for the other. 

So, you see, this is one particular side of research that you need to use animals. However, all animal work has lists and lists of regulations. You cannot just choose any animal you want and order any number of them. Most importantly, there are regulations as to how the animals must be treated, enclosed and eventually, disposed. For example, you cannot sacrifice a primate even if your research has finished. You have to maintain the animal until the end of it’s days, meaning feeding, healthcare and proper environment. These animals, while bred exclusively for research, are supposed to be maintained appropriately and to work with them you have to present and keep a proper experimental protocol. Any research or biotech facility is supposed to adhere to a complex set of protocols. So what happened in this case? 

Once again, what worries me more than anything is the fact that it has taken 5 years for this to be investigated; 5 years when these animals were most probably mistreated to say the least; 5 years where that company most likely benefited greatly and instead of addressing the violations, resolved to make the animals vanish.

This piece of news is starting to go “mainstream” for lack of a better term, where the story has been (IMO) over simplified and closing with a dangerous “would you want to eat a medical research animal?”. For the record, some animals used in research could be apt for consumption, but that’s a different story.  Sadly, it is news like this that make people angry at research and end up with animal right groups bursting into universities and “freeing” animals…animals that were never in the wild, that are actually harmful for the local fauna. What SCB has done didn’t only hurt the lives of thousands of animals, but has also affected the image of animal research which, let’s face it, isn’t great. And now we are left with the disappearance of almost 5000 animals and a lot of “#notallanimalresearchers” conversations to come.

Me and my Soapbox: The importance of proper journalism on science/medical topics

 
 
You probably saw it in the news: a woman that (somehow) was called a wellness guru admitted that in fact she never had cancer and hence she was never cured by her diet. Now, I will admit that before these news, I have never heard of her. Or maybe I did, but I discarded her story as of yet another person, with no medical/science background whatsoever, selling her image (insert snarky comment about "Food Babe").

But what really bothered me with this whole thing was not that she lied, not even that yet another person was given (unsolicited) advice about a subject she/he had no real knowledge about. No, what really bothered me was this:
Gibson, whose survival story was praised by the media despite never having been verified, has now admitted that she didn’t have, and never had, cancer.

Because the problem I see, not only with her, but with a lot of the self called "health gurus" is that they tell a story, a wonderful "heal with no pain" story that almost everyone would love to believe and then the people who hear this story eat it all up without taking the time to question it and more importantly, verify it. Now that she admitted the whole thing was a lie, you can find almost half a million news sites if you Google her name, either shaming her or shaming the ones who believed her. Very few are addressing the source of the problem: no fact checking whatsoever. It's the same situation with Jenny McCarthy and vaccines, Vani Hari and "unpronounceable words" or Dr. Oz and his "miracle diets": no one is verifying before sharing and endorsing their "wellness approach". Or rather, the people doing the questioning and fact checking are being dismissed.

There are numerous people who dedicate their lives to do proper science (or medical) journalism, who spend their days making all these topics accessible, well explained. And yet, when a new food/health/diet/whatever guru (also, shouldn't we stop with this already?) comes out, it would seem like they don't matter. It would seem the "best case scenario" is a talk show where one of the aforementioned people will discuss their views with a scientist, acting like both sides have the same weight and where (sadly) the person who screams the most but knows the least will gain the sympathy of the masses because "the scientist is just using big words to confuse us". Kimberly Moynahan wrote a great post on how this attitude would be considered ridiculous if it were another subject, other than science.

I've said before that we need more scientific and medical journalists, and I stand by it. But more and more it seems to me that we also need more general journalists that do all the homework and not get sold for just a "human side" story. We need the people sharing these news to do the proper fact checking, to discuss it with the people who have the background to point out inconsistencies and validate things that (in context) might make sense. Otherwise, these snake oil salesmen will keep becoming celebrities and people will keep on ditching science as scary.

Me and my Soapbox: The importance of proper science in fiction

This post also appears in my other blog:A Girl that Likes Books


“I have an issue when they get the science wrong because they didn’t know better, or they presumed that the correct science would have somehow handcuffed them in their storytelling. My biggest issue is when they get the science wrong where, had they told it right, they could have told a better story. I have no patience for that [laughs]. Really no patience for that.”

- Dr Neil deGrasse Tyson

When I read for pleasure, I often gravitate away from non-fiction, having a lot of that in the articles I have to read for work. However, that doesn't mean that I don't enjoy fiction books that deal with science. I do have a problem with fiction books that are a bit too lose with their science background.

I love science fiction and fantasy, you can tell as much just looking at my shelves at home. And as long as whatever phenomenon is going on makes sense in the constructed universe, I can go along with it. However, sometimes in other genres you will stay in our universe (i.e. General Fiction) and that's when stumbling upon misconstructed science terms or theories make me shudder.

A couple of years ago I read a book that kept using the term germs to describe pathogens. While a lot of people use this term, it's pretty much the same as using the term cooties. We have words for infectious or non infectious organisms, why not use them? In the case of this book, it bothered me particularly because the author had a Ph.D in Medical Microbiology. Sure she got it in 1962, but still.

The same way that CSI (any city really) has me rolling my eyes when they do a full genetic background of the suspect in three hours, or when I encounter things like "He invented the DNA", it touches my nerves. While it can seem like a small, inconsequential thing (for the record, no body "invented" the DNA, it was discovered), it can lead to bigger mistakes or misinformation for the general public. And most of the time, this "incorrect" science is the product of not doing their research properly.

Once again, if you are building your own universe, you can make up your rules, and the book might be amazing. But sometimes you just have to look things up and get them right. You can vulgarize as much as you want, but keep the science (or really, the subject you decided to tackle) proper. I get the feeling that we talk about this more with movies and TV than we do with books. The quote I used above is from Dr. Tyson referring to the errors in Gravity. But it applies to a lot of works of fiction. It's a shame really to know that the work you are constructing could've been so much better if you would've done a bit of research.

Some authors will plainly say it: I went for a fictional world because I did not want to do the research. That is fine and up to a certain extent understandable. But, and I know I am repeating myself here, if you have decided to stay in our universe, just with fictional characters...get your facts right. That's all.

What are your thoughts? What are your best examples of proper science in fiction? your worst? Let me know in the comments.

Me and my soapbox: The 21 day sugar “detox”




Every day I hear about a new diet*/cleanse/detox program and most of the time I just wave them away as fads and unnecessary. However, when I saw that a blogger friend mentioned she was going to do the “21 day sugar detox” program, my ears perked.

I read her post and I gathered that what she wanted to do was to lower her sugar cravings/consumption coming from extra added sugar in a lot of processed foods…but then I learned that the program also had fruits listed as “No foods” and that’s when the biologist in me got a bit alarmed. Let me tell you why.

Beginning with the word detox. It really bothers me how this term has been thrown lightly lately. To be clear, a detox process involves getting read of a TOXIN which is a substance with poisonous effect (think snake venom). To some extent it can be applied to substances (for example drugs) that have a toxic effect. However, for some reason people use it nowadays to refer to getting rid of almost any substance that has been deemed responsible for bad health (fast food detox, sugar detox, soda detox, etc) which off course is not the same. Normally, and unless you have any type of liver damage, all this removing of toxins is being performed by your liver, including alcohol, drugs and other substances. Regardless of what you see in TV/Internet (a lot of marketing going on with the term), your body is NOT full of toxins.

The main problem with a lot of people’s food intake is the abuse of certain foods. Any excess has consequences, and so when someone who has been eating a lot of fast food goes on a “cleanse”, they see some results very fast because you are basically giving your body some time off. This doesn’t mean that your liver wasn’t detoxifying before, or that your kidneys weren’t filtering.

So, in general, if a new diet seems to be telling people to cut their excess, I don’t have much to say. I don’t do diets, but if it helps some people to get rid of not so good habits, why not? But then, you have programs that go overboard (eat only protein, don’t eat any fat, throw away all the sugars!) and that’s when I roll my eyes so hard I can see my nape. The fact of the matter is: your body needs protein, fat and sugar. Just not insane amounts of it.Today I will only talk about sugars, but if you guys want, we can brush other detox diets later on.

So what is sugar?

Sugar is a general name that we have given to small carbohydrates (saccharides). A carbohydrate is basically a molecule with Carbon, Hydrogen and Oxygen. Now, there are some differences between molecules (in their structure for example) but we can stick to that basic principle. If we have a single molecule we refer to it as a monosaccharide (glucose or fructose for example); when 2 molecules interact, either from the same type or 2 different molecules, we call them disaccharides (lactose for example is made by 2 different monosaccharides); as the chains of this molecules become longer and more complex we call them oligosaccharides or complex sugars (a great example is cellulose made of several thousand molecules of glucose!) and as they become more complex it makes it harder for a body to get energy from them. So sugars are a bit everywhere, you even have sugar on your DNA.

Why do I need sugar?

Sugar in any of its forms is a fast provider of energy. Not just energy as in “I can run a marathon” type, but the energy for your neurons to communicate with each other, for example. Actually, as it so happens, the brain can only get its energy from sugar forms. We also have long storage of energy in the form of fat, but these are kept as reserves for when the body doesn’t have another source available.

I mentioned we have sugars in our DNA too. Also, some proteins need sugars to be added to them in order to perform their roles such as, for example, cell to cell recognition, binding immune cells to injury sites (open wounds), forming glycogen in your liver (see? We went full circle with the whole detox thing here) for future usage. So you see, sugars are important to have with us.

Then I should eat a lot of sugar, no?

No. As I mentioned, it’s all about balance. First of all if you drink a glass of milk, sure it has sugar (lactose, remember?) but it also has other stuff: fat that will be stored for later, cholesterol that you also need in certain quantities, protein and vitamins. So when you drink your glass of milk, your body can access that sugar in the moment and THEN during the day use the rest of energy it stored. However if you keep giving it fast access to sugar, it will still store the rest, but will never use it.

There is another problem with consuming too much sugar and it’s the fact that your perception threshold (the moment you realize something is too sugary/salty/bitter, etc) for sugar is already quite high. As with anything, you can expand this threshold. So eating a lot of sweet things makes it so the next time you will have to add even more sugar to feel satiated. The same is true for other flavors but they have smaller thresholds to begin with.

So…what do I do?
As I mentioned before, when I thought my friend was cutting added sugars, sweets in general, to lower her “sweet tooth”, I felt like sure, go for it, I should probably cut on the gummies too (remember excess Is never good). But then, when I saw the food list, where it says no to fruits…no, no, no. You need sugars, even if little amounts. Plus for the record, eating 2 small carrots gives you about the same sugar intake of eating a small apple, so I don’t see the “logic” of this list that lets you eat carrots but not an apple (I love both, but seriously, it makes no sense).

What I would suggest anyone do (and please keep in mind I am not dictating a diet here) is to keep everything in moderation. Say you notice you snack too much on sweets? Start lowering your portions, and if you still have the craving, remember that it takes a while for the satiated feeling to settle. So wait a bit, drink some water. Don’t add extra sugar, and don’t just replace regular sugar for sugar supplements (aspartame, saccharine) as they can just increase your threshold.
