Peer Reviewed Magic: Moringa

Moringa is everywhere in Singapore it is THE superfood right now. Moringa also known as drumstick tree is native to northern India up into the foothills of the Himalaya. It is widely cultivated in the tropics where the young seed pods and leaves are eaten. Benzoil is derived from its seeds, a powder of its leaves is seen as a super supplement, used as herbal medicine and water purification.
Wait what? Water purification? No…..

That was my reaction when I was reading a description at Bollywood Veggies this weekend. It can be used to make dirty water drinkable? You have got to be kidding me. So when we got home we looked it up. Crushed moringa seeds are put in cloudy water, reduce bacteria and other impurities and within hours it is drinkable.


Dirty water + Moringa seed = clean water?????

That is a pretty impressive claim. That is the idea but does it work and if yes… how?

Moringa in action!

I found a press release on a study at Penn State. On the use of Moringa seeds to purify water the article says:

“That has been known for some time,” says Stephanie Butler Velegol, environmental engineering instructor at Penn State. Women in ancient Egypt reportedly rubbed Moringa seeds on their clay water pots, and dried powder from crushed seeds has been used as a handwash for many years.”

So how does it work? It appears that when you crush the seeds a positively charged protein called Moringa Oleifera Cationic Protein (that is the scientific name of the plant, cation means positively charged ion, and protein pretty descriptive) MOCP from in the seeds is introduced to the water. This protein kills some of the microbial organism and causes them to clump together and settle to the bottom of the container. You can’t however then store this water, the organic matter from the seeds will remain and become a food source for bacterial that haven’t been killed.
So. The protein in the seeds causes clumping and kills bacteria (but maybe not all of it) and then settles to the bottom leaving clear water at the top. Wanna see it in action? I did!

How cool is that!? Sounds like that is some serious magic that actually is backed up by peer review and now we know a little more how it works.

Here is the Penn State article

Here is the paper it is talking about (if you are interested in the PDF of this and can’t get a copy just contact me and I will download one and pass it along!)

The science behind the Mercury/Silver Dime Charm

I was inspired to look into and share the chemistry behind the silver dime charm this week. The first flash of  inspiration was my lesson in powders (I have been taking very informal classes in hoodoo recently and love it), and the  second was a post by Candle Smoke Chapel that they had a new etsy listing of silver dime charms. So thank  you both for the inspiration! Now on to the science!

The science behind the Mercury/Silver Dime Charm 

The mercury dime, or silver dime charm, if you are not familiar with it goes like this: If you wear a silver dime around your ankle and if you walk through a powder (ex: hot foot) the dime with absorb the hit and tarnish, keeping you safe.

For the sake of example let’s look at what happens if you are wearing a silver dime and walk through hotfoot powder. Hot foot powder is made primarily of sulfur and crushed hot peppers with the option of other nasties. The key ingredient here in terms of what is going to physically happen to your silver dime is the sulfur.  The sulfur in the powder will react with the silver on the surface of the coin, causing it to “tarnish” in a RedOx reaction. I found this awesome old school video about the reaction:

For the sake of repetition here is the reaction again:

2Ag(s)+S(s) -> Ag2S(s)

Sulfur (S) basically wants two more electrons… wants them REALLY BAD, and Silver (Ag) has an extra that it isn’t too attached to. Sulfur takes one electron from two silvers making it S(2-) and each silver Ag(1+) causing them to  the  two silver and the sulfur atom are now sharing, and create a black solid Ag2S, which is the tarnish you see on silver.

Silver doesn’t need solid sulfur to tarnish. In fact Hydrogen Sulfide gas that can be found in the atmosphere can also react with silver. H2S (hydrogen sulfide gas) can be the result of the decomposition of plants and animals, or some industry of some sort. In fact just about any sulfur compound can cause tarnishing including hardboiled eggs, mayonnaise, mustard and even rubber bands. If you have ever worn silver jewelry into a hot springs you will have also seen this same reaction.

In conclusion:

The roots of this charm seem to be the fact that several popular powders that are used when throwing against someone ( crossing powder, goofer dust, and hotfoot powder) have sulfur as a main ingredient. This sulfur reacts to the silver worn at the ankle by tarnishing through the reaction 2Ag(s) + S -> Ag2S(s).

This reaction is an example of an oxidation and reduction  (RedOx) reaction. For more on this type of reaction here is another video:

My thoughts on the Us Vs Them problem with Science and Religion

Today I am writing as a scientist. I wanted to comment on the Bill Nye Vs Ken Ham debate that I did not watch. I don’t want to comment on the debate itself but the mentality that this debate comes from. First of all I want to say that I blame both sides for the following problem.

There is a very pervasive “Us vs. Them” mentality when it comes to science and religion (and, for that case, science vs art). This is the mentality everyone is divided into two categories the “us” and the “them” and there is no room for anything else. It is a very black and white mentality. When we look at how this relates to science and religion we see this manifested in the division between “science people” and “religious people”. These two categories have also grown to encompass more stereotypes as well.  If you are a “science” person then you are a liberal atheist and likely live in an urban area. If you are a “religion” person you are a conservative and Christian and live in a rural area.  I think this mindset is very damaging and dangerous to our society. It breeds a reactionary mindset and makes every debate personal and full of emotions. It creates boxes that we put people in, and they are not allowed to be anything but the box we put them in. I am a scientist and therefore if you are not, and you are religious, you are a “them”, and the “thems” don’t like us. Just like “Christians” have become a group “scientists” have too. We are not taken as individuals and certainly are now allowed to disagree with each other. If we do then it reflects badly on all of us, and we all have no idea what we are talking about and can’t be trusted on any matter. In the science community religion is a dirty word as well and is very looked down upon.

Using this Us vs Them mindset means that we have made an artificial black and white world out of a gray one. First of all, you can be a Christian and not believe in creation, just like you can be a scientist and not be an atheist. In fact, I know Christian-scientists and I even know a geologist who IS a creationist. It is not all black and white. I think it also helps to point out, that the Catholic Church accepts evolution, so you can’t even group all Christians together.

The problem I have with the “us vs them” mentality is that both parties start off defensive. That is no way to have a conversation. My personal view is that religion does have a place in a rounded education, but only because it has had such a huge impact on human history and art and other intellectual pursuits. Also a fun exercise is the history of thought on the age of the earth and the different ways it has been calculated. How did the Romans decide what year Jesus died in, and were they right? How was the age of the earth calculated from the bible? How else has it been calculated in the past? What method do we use today, and what are the errors associated with that calculation? That discussion is valuable in a science classroom. It’s like doing a proof and showing all the steps in math, and even talking about the different ways it was tried in the past. I have always loved talking about the changes in scientific thought through the ages.  I think it is fascinating and valuable to understand how we know what we know today. It also reminds us that just because we think we know something, does not mean we won’t later learn something else is true. Plate tectonics itself is a relatively new scientific idea. Also, let us not forget that many of the founders of modern science (if not all) were religious.

So now let us return to the debate and why I can’t watch things like that. I have personally been attacked before simply for saying “I’m a geologist” when someone asked what I am studying. I was polite about it, but since the other party didn’t listen to me it felt like talking to a wall. There was no back and forth (which I would have enjoyed). This mentality backs people into their respective corners. I am not an atheist and that is something I tend to not discuss with my friends and colleagues because of the us vs. them. I’m too close to the situation and it makes me too upset. So I didn’t watch the debate because I don’t think there should need to be a debate.

DID YOU FEEL ANY EQs THIS WEEK!? Make sure when you do you head on over to the USGS earthquakes page and fill out a “did you feel it?” report!


Well, yeah, I still am speechless.

You guys (and by guys I mean fellow pagans) should also know that mother earth… not the caring let you do it the easy way kind of mother more like, does exactly what you are not expecting just to see that confused look on your face….
so this makes me very sad. Please be nice to seismologists, we live where there are EQs just like the rest of you and we do try, very hard, we just can’t do the impossible, we are only people.
