A couple (6?!) months ago I was contacted by Alexandra Pajak, a graduate student from the University of Georgia, with an interesting project. She told me that she was working an album based on the genome of the HIV virus called Sounds of HIV. It immediately caught my attention and I said I’d love to give it a listen.

Sounds of HIV is a musical translation of the genetic code of HIV, the Human Immunodeficiency Virus. Every segment of the virus is assigned musical pitches that correspond to the segment’s scientific properties. In this way, the sounds reflect the true nature of the virus. When listening from beginning to end, the listener hears the entire genome of HIV.

So how does one listen to DNA, RNA or proteins you ask? It’s somewhat explained by Alexandra’s notes:

DNA-based music is music in which the natural chemical properties of DNA is translated into music. In English, the nucleotides adenine, cytosine, thymine, and guanine are abbreviated with the letters a, c, t, and g, respectively. Since A, C, and G are also musical pitches in the Western melodic scale, these pitches were assigned to the matching nucleotides. To form two perfect fifths (C-G and D-A), “D” was arbitrarily assigned to musically represent thymine. The notes of the A minor scale have been assigned to the amino acids based on their level of attraction to water.

On Sounds of HIV, depending on the track, nucleotides and/or amino acids “play” as music. Tracks 1 and 10 are based on the first and last nucleotides of the DNA chain. Tracks 2-9 “play” the proteins and sometimes the nucleotides on top of the proteins.

I’ve listened to the full album and have found it to be a bit strange at times but was mostly expecting the music to very different as it is in fact driven by genetic information which most probably didn’t evolve based on it’s audible features!
You can listen to excerpts at Amazon and if you like what you hear, be sure to buy a copy as a part of the proceeds from the sale of this album will go to the Emory Vaccine Center which does extensive AIDS research.

From what I’ve read about her, she was a small framed woman, that worked hard in keeping her brother focused on what he loved, scanning the night sky. Not only did she entertain guests, keep the house, sing and care for her sibling, she also fell in love with the stars as she accompanied her brother on his many nightly scans.

Considering all the chores, the singing lessons and the long nights, she played a big part in her brothers success and even got her name immortalized on an asteroid. Her second name, to be correct. Oh, and a moon crater too.

Update:
I’ve received a few emails regarding this post. I’m sorry if I made it look like all Caroline Herschel did was take care of her brother. I did not mean to pass on that message. I wouldn’t have picked her for Ada Lovelace Day if that were the case.

Considering her difficult upbringing, the fact that she was a woman in an age where only men were taken seriously in science, living with a very talented and demanding brother, I considered her impact and determination toward science to have been quite impressive. Thus my choice.

I could have easily mentioned another more famous and generally known female scientist, but I enjoyed learning about her life and thought it would be interesting to share the fact that there was a great woman doing incredible work in astronomy. Even if she was overshadowed by her brother.

I could go into detail about this study but what I wanted to mention here was not necessarily about the potential candidate genes or their possible functional implications. I wanted to mention the awesome web application that was produced along with this study which allows folks like me (read lazy!) to go over their datasets with minimal effort.

The Broad Institute‘s Tumorscape is a portal that allows one to browse/search through a database of copy number alterations across multiple cancer types. Basically the findings of the previously mentioned paper.

In my opinion, this is much better than having to go through the raw supplementary data. If I were interested in further pursuing any of the studies performed, I could download the supplementary data, but if I’m just interested in browsing the results of this paper, the Tumorscape makes it far more pleasant.

There is obviously an overhead related to producing this type of portal, however the sheer number of people working on this project and the amount of data produced definitely justified the creation of such a web application.

Sorry if the title of this post was a bit misleading, but hey… it should be awesome, right? :)

Supplementary data should be awesome like this

With this in mind, here’s a few more interesting life science related apps that I have recently added to my iPhone and iPod Touch which may be of some interest.

I was amazed that this took so long but Nature.com only recently came out with an iPhone app that is free for download and gives you access to their latest content (Don’t mind the pay-wall :) ) and provides you with an easy way to search and save content.

While using Nature.com’s app, I found Promega’s app (also free) that although needs some design work, it does come packed with great content. Protocols of all type, video media and a simple BioMath calculator which helps with unit conversions.

Another app that’s just recently become available is made by the folks at Invitrogen. Their app called Daily Calcs helps with routine calculations like Molarity calculations, Molecular weight, dilutions, unit conversions and interesting cell culture references. And it’s also free.

If browsing genomes on the go is your thing, then I must recommend you download the GenomePad which basically provides you with UCSC’s Genome Browser on your iPhone. I find it to be a bit difficult to navigate and parse all that data on such a small screen, but it’s great for quick look-ups. Did I mention it’s free?

The last two apps I’ll mention are not so much tools but didactic apps in the sense that they are awesome learning apps. One called Mitosis provides an interactive way to learn about the process of cell division and the other is a science glossary packed with science goodness. Once again, free and free.

As you can see, I’ve only mentioned a hand full of free apps this time as I haven’t had or required to purchase any other science apps. However, if there’s a scientific app out there that you think is worth spreading the word (free or not!), please let me know.

Synthetic biology is great, I really like everything about it. I truly do. I had the privilege of meeting and seeing the work of some of the pioneers in this exciting new approach to genetic engineering last year at MIT.
I must emphasize something about these bioengineers. They are extremely smart, hard working, innovative and, did I say it? smart biological engineers!

So what is it that ticks me off about some of the synthetic biology related articles? It’s not the “Frankenstein” remarks, it’s not the bioterrorism worries and it’s not even the JC Venter veneration!
Nope, it’s the constant comparison between synthetic biology now and computer science in the mid-80′s.

This comparison just brings along a whole truck load of babble that I think is incorrect. Mentioning that synthetic biology makes engineering biology so easy you can do it in your garage as if putting together a new lego set. Stating that people are sequencing their own genomes in their closet as if it were something like baking a cake in your microwave.

These stories are either incomplete or incorrect. You choose. I think that the average reader is going to misinterpret these articles. It’s quite notorious by looking at the comments made on the online news articles.

No doubt that synthetic biology makes engineering biology easier but it’s not something you’ll be doing in your garage/kitchen/bedroom closet. At least not legally, or with much success. Besides, the people that seem to be championing such efforts are mostly graduate students in fields related to biological sciences, not your regular Make magazine reader or science buff.

I’m not against the DIYBio movement. I just don’t think it should be synonymous with “garage synthetic biology”, because it’s not. They have a ton of really interesting projects that I believe would make more sense to put effort into.

So yeah, let’s not get ahead of ourselves.

In summary: Synthetic biology is great awesome! But unlike Obama, it’s not your new bicylce.

WOLFRAM|ALPHA AND ENGINEERING
And now, let me just put in my quick 2 eurocents (roughly 2.84 US cents) regarding Wolfram|Alpha.
I’ve found it to be a really valuable tool with any work that requires looking up tabulated data and proceeding with any type of calculations upon such data.

Wolfram|Alpha would have been such a time saver while I was working on my biotech industries project. Loads of engineering calculations and data to look up that would have been made so much easier. No need to skim through Perry’s handbook, through process engineering and transport phenomena books looking for figures, graphs and constants. Wolfram|Alpha would have made most of it a simple search.

In summary, Wolfram|Alpha is, in my opinion, a really large and structured Almanac with a super scientific calculator mashed-up into it and therefore a very useful reference tool. However, it’s pretty poor when it comes to anything outside it’s “comfort zone”, like life sciences. I’ll have more to say about this in a future post.

Being interested in all things science, one of the latest uses for Twitter that caught my eye has to do with Open Access repositories.

Tipped by fellow Twitter user Eloy Rodrigues (@cibertecario02), there are currently two open access repositories currently tweeting new deposits. They are Southhampton Univeristy’s ECS repository (@eprintsecs) and Minho University’s RepositoriUM (@repositorium).

I find this to be an interesting way of keeping up with the knowledge flow at universities or departments within universities. I hope to see other OA repositories join Twitter soon.

Well, today something caught my attention regarding two of these terms, namely anaphase and kinetochores. It seems that way back in 1956, a Portuguese researcher by the name of Miguel Mota made a visionary connection between them and published it in “A new hypothesis for the anaphase movement“.

Miguel Mota conceptualized that chromosome movement during anaphase is due to an active role played by kinetochores, minute protein bodies located at the centromeric region where spindle microtubules attach, which he envisioned to act also as “engines” that move chromosomes to the poles.

Mota’s models were only proven supported by more experimental data in 1987 (30 years later!) by Gorbsky and colleagues.

As a tribute to 83 86 year old Miguel Mota’s prescient findings, a symposium entitled: Mechanisms of Chromosome Segregation will take place in Porto, Portugal on the 9th and 10th of March 2009.

There is an impressive list of invited speakers to this tribute event with Gorbsky himself among the list.

I just love learning about this type of stuff. I had no idea that there was this impressive Portuguese researcher named Miguel Mota until today. I wish emphasis was given in school on teaching more about the who’s and the how’s and not only the what’s. Make sense?

So, what does it do? Compounds is a stoichiometry “grams-to-moles” calculator and works like a charm:

1. Add compounds to the beaker.
2. Rotate iPhone to enter the formula.
3. Type in the formula for each compound using the Period Table as a keyboard.
4. Enter the coefficients (or ratios).
5. Shake! to solve.
6. Adjust the amount in grams of any compound and see the results immediately.

I’ve had the privilege of giving it a test run and I must say it’s pretty cool. The “shake to solve” feature is great!

Keep in mind that it’s not a Periodic Table app, it just presents the periodic table as an easier way to type in your compounds. Nice touch, if I must say so.

It’s not yet available for download at the App Store so I can’t provide a direct link, but be sure to find the link here when it does become available.
