Ricin: A Potent Poison


Now I don't really talk about anything on this site that deals with anything biochemistry related, but I will make this an exception due to the state of current events. Ricin might be a word that you have heard recently in the new, about the poising attempt on President Obama by an Elvis impersonator.  For those who don't know what Ricin is, it is a protein originating from the same plant that gives you castor oil. It's job in the body is a nasty one, as it inhibits protein synthesis (which is pretty much everything important in a cell), more specifically it acts upon the ribosome (a small organelle which synthesizes proteins). It's categorization of inhibitor is a Ribosome Inactivating Protein, which cynically has the acronym RIP.  Although this is a very deadly poison (a gram worth to kill), there does exist an antidote, but the survivors will have major organ damage and will have a shortened life expectancy.

Biology 12 BC Study Guide

I just realized that I still have my ginormous study guide that I made back in high school when I was determined to get 100% in biology (of which I didn't achieve unfortunately) because I was certain that I wanted to go into medicine.  I'm not joking when I say this thing is large, it is 31 pages long, and now you must think "Wow, this guy was really cool in high school, spending his friday nights making study guides".  It is true that I would compulsively make elaborate study guides, mainly for the sake of keeping all of my information organized. Enough of the bantering of my crazy educational antics, here is the study guide:

Should Search Engines Block Queries to The Anarchist's Cookbook?



This thought came to me when I decided to search for The Anarchist's Cookbook to calm my curiosity of how easy it is for anyone to get a hold of it. When I searched Google for it, the first page presented me a number of places where I could purchase the book, along with a full pdf file of the book. I was quite surprised when I found it so quickly, and quite disturbed at that as well. I am fully against internet censoring to the extent of websites being shut down (other than that of illegality issues), but I believe that search engines such as Google, Bing, and Yahoo should take a step towards assuring that the average internet user cannot obtain information like this.

The problem that I have with The Anarchist's Cookbook is not the fact that it explains how to make explosives, I think it's good information for people who know what they are doing, such as chemists, but I have a problem with the fact that it is written for the average person, who has had no safety training in handling chemicals. It explains how to get certain chemicals from off the shelf products in order to construct bombs, and other such dangerous weapons, rather than having to get chemicals from a supplier such as Sigma-Aldrich, who makes it impossible for the average person to obtain. If someone really wanted to hurt someone, they should have to gain the knowledge first before jumping right to making the explosive from a set out procedure. In that time planning it out, they could very well change their mind. An example of this is the Drano Bomb, where kids can make a bomb out of common household items, which can cause serious damage, as reported here. Reports have been made of people loosing fingers while holding the water bottle, which is an unexpecting object to be a bomb since we see bottles littered all the time.

In the end, we have to ask ourselves if information like this should be free to the public, through being written in layman’s terms, rather than in academic terminology that could only be understood with four years of post secondary education, along with the understanding and appreciation of what we are dealing with.

Ponderings Of Where Science Education Should Go


Just as a forefront, I don't want to make myself out to be an expert in the educational studies; these are merely my observations and thoughts of where I believe we should be heading with our public elementary and high schools.



A step back from memorization
A key part in education right now is the preparation for standardized tests, to reshape a student to be able to answer predictive questions, selecting students who aren't well rounded, but excel solely in this category, while leaving their creativity behind. This method doesn't teach children to ask questions because they soon realize that there is only one right answer, where in the real world a person needs to ask themselves questions in order to problem solve, or to see a problem all together. I can't tell you the number of times I have heard an arts student say that they didn't like science because there was only one right answer, and that they preferred to have an objective look on their topics. But this here, is the beauty of science; anyone can disprove anything that is considered “true” with sufficient evidence, creating a paradox in how we test the subject. If education can step back from the emphasized learning of knowledge and spend more time exploring the beauty of the scientific method, people won't be as afraid of science. I'm not necessarily saying that I think everyone should go into the sciences because of this, but people who are in other fields shouldn't have a fear of it.
In line with this, there may also be a problem with this method for the upcoming generation who are surrounded with more and more electronic gadgets connected to all human information. With an increasing dependence on technology, the need of memorizing small details diminishes proportional to the easiness of accessing the information [1]. In fact, it has been proven that if the information is easily accessed, our mind will refrain from storing it in our long term memory. From this, we may see a change with our next generation in their ability to hold long term memories of small facts. Because of this, we need to push for a stronger investment in the creativity and imagination of students. It was Einstein who stated that "Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world”.

Consequences of the current education system
One key result of this is the fact that 3rd year genetics is considered to be one of the toughest courses for biology undergraduates, but for other majors such as mathematics, physics, and chemistry it seems easier because of their problem solving experience. Up to that point in university biology students are made to only know memorization as the medium of education. They aren't made to problem solve, create, or learn the scientific method until later in their degree; all they are doing is building up their knowledge to be able to problem solve later. As much as this method has worked for years and years, I believe that we can do better in educating students so that when they do get to their first genetics class, they have the problem solving skills to be able to excel in the course.
As have just finished my undergrad, i have witnessed a slew of grad students who eagerly boast in their academic excellence, while in their T.A. duties saying things such as "Wow, you don't know that", and refuse to teach an elemental concept. This power trip blocks the process of education; being in an employee of an academic institute, they are there to help educate and build the body of science, but instead think selfishly in looking at their academic achievements. They are the kind of people who were bred out of this academic competition that exists in a capitalistic society, a concept of every man/woman for themselves, only yielding the best of the best. But these people fail to see what science really is. They fail to see that it is a body of knowledge that is dependent of everyone working as a whole.

Ending Comments
It will be tough to be subjective through a land of no standardized tests, creating a lot of issues in how to test the mass number of students without multiple choice. The recourses to mark thousands of objective tests at a time are just not here unless we can find a testing method in the future that both appeases this method along with the practicality of marking.
I'm not necessarily saying that we should put all of our teaching into the creativity process because we will still need to have memorized a great deal to get anywhere in the scientific world. Our brains rely on connections to get anywhere, which requires us to have this knowledge in our memory. We need to see the comparisons that the computers are unable to see, this also being known as human intuition.
