Malicious Scientific Miscommunication

As you probably have seen in malls or in online ads, there have been a recent surge in products known as “energy bracelets”. Examples you may have heard include “negative ion” bracelets or “hologram bracelets”.

You have probably also heard that these bracelets can improve balance, treat disease, and perhaps even save the world. Skeptical, you might ask the salesperson why or how these bracelets would help you. They would then give you a whole lot of scientific jargon and explain why each piece of false evidence is true.

If you were to look at a typical bracelet website, such as  Energy Force,  you would find that they make numerous claims such as

“ENERGY FORCE…regulates your body’s frequency to an ideal level. Optimal health and peak performance occur when your body maintains ionic balance (the exchange between negative and positive charges) and free flowing energy pathways (harmony) at the optimum frequency.”

How does this bracelet maintain balance? Why does ionic balance matter for health? How does it help you stay healthy? Why is it good to have the “optimal frequency”?

In reality, you wouldn’t find any answers to these questions, because these claims are not scientifically proven.

However, there are some much more devious scams that try to trick you in much less obvious ways. They do this by manipulating scientific data in order to make it fit their claims.

Some examples of the claims made by EQbandz

1. “Anti-oxidising: US Dept. of Agriculture found that anions led to 52% less dust in the air and 95% less bacteria“
2. “Emotional: 25 people tested with seasonal affective depression (SAD) found that anion treatment proved to be as effective against SAD as antidepressants without the side effects of these drugs”
3. “Immune system: Norwich Union Insurance Group: Reduced incidence of sickness and headaches by 78% when exposed to 1000 anions per C/C.”
4. “Aging: Dr Nagao Katsharu, Japan found that skin cells were replaced at 2.5 times normal speed with anions by accelerating the delivery of oxygen to the cells and tissues.”

These claims sound like the band is 100% scientifically proven to work! However, if one was to track these down, they would find that  these claims reference studies that were done using gigantic air-ionizer fans, which are much more powerful than a small bracelet. Interestingly a simple Google search reveals that the “doctor” in claim 4 does not seem to even exist. There are much more problems with these claims, and they can be found here.

katatrepsis has this to say:

[The companies are basically saying] “look at all this good stuff air ionisers do, here’s a bracelet that does the same thing” [which] is like saying “look how great scuba equipment is for breathing underwater, here’s a paper bag filled with air”

The conclusions that can be made from research have to be very carefully constructed. By taking legitimate research and formed their own unscientific conclusions, these companies can maliciously miscommunicate the studies to trick potential consumers.

As students in a science communication class, we have a duty to be able to identify these miscommunications and set them straight for the public, as katatrepsis does.

The language of DNA

Within each and every living organism, there are millions of books describing things from “how to move” to “how to eat”. These books are written in DNA: language of life. Ultimately, DNA is how nature writes about how to live, and the readers are how all living (and some “dead things”) survive. Even your own body is reading from your own library as you read this blog.

But within this massive collection, we, as people, cannot read most of it because we do not yet understand the language.

However, what we have figured out, thanks to genetics, cellular biology, and biochemistry, are the basic letters of these books; we have the codon table.

Codon Table

The codon table encoding the 20 essential amino acids used in all walks of life. Obtained as a screen capture from http://en.wikipedia.org/wiki/DNA_codon_table

What this codon table tells us is the 20 letters of the DNA alphabet, representing the 20 amino acids. When there are multiple letters together, they can spell a word, also known as a protein.

We have also figured out some parts of these books through areas called open reading frames. These areas use a process called transcription and translation, which is described in the following video found on youtube posted by redandbrownpaperbag.

We also have clues and insights into some other parts of these books, namely the promoter and termination sequences. These parts tell us where there is an open-reading frame, essentially acting as quotation marks to direct the cell’s attention to a specific location.

Despite all these advances in understanding the language, we know very little in reality.

First of all, there are no known “rules” to writing words, because a word can be as short as 2 letters to as long as a million letters.

Secondly, we do not have a clear picture of how different areas within the genome that are neither open reading frames nor promoters/terminaters interact with the cell, or why those books are there in the first place. These sequences are currently hypothesized as useless, but may be useful as the ENCODE project suggests.

Finally, some words, even with the same spelling, can have many different meanings when they are in different compartments of a cell, so figuring out what they actually mean is quite difficult.

The secret language of DNA might one day be uncovered; someone who can speak “DNA” might be able to take a piece of DNA and then tell us exactly what that DNA is used for, which can advance science from treating and preventing disease, finding new applications for cells (i.e. sustainable fuel), or even figure out what consciousness is. Knowing how to read DNA can open up a brave new world in understanding life as we know it.

Just like how the discovery of the Rosetta Stone lead us to understand the Egyptian language, we may be able to slowly construct our own Rosetta Stone, through genetics and biochemistry, to unravel the mystery of DNA.

The hope is that one day, understanding an organism will be as simple as reading a book.
