Carbon Footprint
Global warming is a serious issue if you are concerned about future generations who will live 100 years down. As the international leaders are trying to set up regulations and reduce the global warming, it is necessary that citizens in under-developed and developing nations be educated on Global Warming and the need to go green. "Carbon footprint" is probably the first terminology to understand in this process.
I came across the following links that I consider to be good in educating about carbon footprints and global warming in general.

Festivals, Society and Science
Snowflakes have always evoked a sense of awe owing to their beauty and elegance. Various shapes of snowflakes are used in Christmas cards mainly for an aesthetic value and to denote the winter season. However, it is not common knowledge that snowflakes are always six-sided - hexagonal - owing to water's property. For quite sometime now, I have counted the number of edges of snowflakes appearing in commercial ads...and was always intrigued by the nonconformity to the "six". I was getting into the impression that I was wrong about my knowledge of the hexagonal structure of snowflakes. However a recent correspondence in Nature by Prof. Koop from the Bielefeld University helped me assert that I was indeed correct.
I really appreciate Prof. Koop's effort to bring it to the attention of the media that many of the commercial ads are depicting the snowflakes against the laws of Nature. Even as we celebrate festivals and try to include Nature into our celebrations - or perhaps as sources of inspiration and beauty - let us do it the right way. In my opinion, this is one of the responsibilities of Scientists: ensure that the layman gets to appreciate Nature for its elegance and beauty in the right spirits.
Once he gets to learn the intricacies and complexities of Nature, his appreciation for Science would increase and critical thinking for productivity would be automatically be inculcated.

THE SEARCH FOR EXTRA DIMENSIONS
I was fortunate to attend a talk on "The search for extra dimensions" by the Indian Physicist Dr. Sayen Kar at IIT Kharagpur. He highlighted that there are numerous experimental observations in Physics that can be explained only if we invoke the presence of extra dimensions (that is apart from the usual x,y,z and time dimensions). However, these dimensions become "visible" only at sub-micron length scales and requires high-energy techniques (like the Large Hadron Collider). I couldn't really imagine the presence of an extra dimension. It was hard convincing myself. However, it struck me that this would have been the state of mind before people discovered microbes! Nobody knew what caused diseases. The invent of microscopes was a milestone in knowing the microscopic world - organisims not visible to the eye. Similarly, I think we need high-end techniques like the LHCs before we really explore and perceive the presence/absence of the extra dimensions. In all cases, nothing can be ruled out until proved otherwise! :-)

THE SOCIAL RESPONSIBILITY OF SCIENCE
I thought quite deeply about the social responsibility of Science when I wrote my previous blogpost (click here). However, I was very skeptical of how much my view was right, though I did get a few feedbacks agreeing to my opinions. A recent article in SciAM "War in Peace" parallels my thoughts. The author very clearly points out "Discerning the merits of competing claims is where the empirical basis of Science should play a role". The competing claims may be in any area. I am indeed happy that I understood this aspect of Science, quite right, thanks to Feynman of course! But the question is, why don't everybody who holds a degree in Science understand this?? Wouldn't the world be a better place if everyone agreed to this aspect? In the same issue of SciAm, Michael Shermer (click here) informs us of a research work in psychology that identifies 5 innate and universally available psychological systems upon which our senses of right and wrong rest. The underlying basis of opinion difference is now delineated!!

HUMAN GENOME SEQUENCING IN INDIA
Recently, there was much news that Indian scientists were successful in sequencing an Indian genome. It is a great step indeed for India and shows its promise of progress. However, on retrospection, I wonder if this is any news at all! The human genome project published its first sequence around the year 2000. This means, the technology for sequencing was developed even before that...say 5 years (though the actual root is the invention of the PCR in 1983 - even before I was born!). So, this only means that Indians are lagging behind by at least 15 years now!! In addition, I learn from news that the sequencing technology license was bought from an european organization. So, what was so indigenous to India to celebrate the sequencing? Was there any break through data that leapt out - at least as of now, NO - there hasn't been a publication yet! So, why did the government choose to announce it prematurely? I have no clue! There are lot of things to do with sequencing - population genetics of the different races, cause for the malarial susceptibility etc etc etc. Couldn't the scientists have waited until there was good data to publish? I seriously don't understand their motive from a scientific point of view when there is no novelty displayed yet.

STAR GAZING
Singapore being one of the most "light-polluted" countries, I never thought there would be an astronomical observatory here. But as it happens, there is one...and in fact, one of the few telescopes on the equator! And what more...they offer 'free star gazing' every friday between 7.45 and 10 pm! The planet on focus today was Jupiter - as that was the most observable celestial body today - perhaps the whole of December. There was a big hood like thing..as we see in the movies... in which the telescope was mounted. I guess the whole of the hood was rotatable to view different parts of the sky. The telescopic image showed 4 moons along with the planet. It just made me wonder how much our 'vision' has improved :P (The proposed site for the Indian Neutrino Observatory has been dismissed by the government). There a lot of things that we don't know and are beyond our imagination too. It is so interesting how people live in so much vanity when there are a lot of stuffs that we don't understand and do not even perceive! That apart, I also saw a small satellite that crossed Singapore while I was there...apparently it reflected the sun's light for a fraction of a minute on its way...and was observable at Singapore. One can get a list of observable satellites in their location for the next 7 days from this website: http://www.heavens-above.com/.
Astronomy is fun and humbling!

Components of Research - Hypothesis- vs Non-hypothesis- Driven Research
Holding a bachelor degree in Science and stepping into a graduate program in the Engineering has been the most arduous task I have ever undertaken in my life. Trained as a Science student with a little research exposure at NCL and NCBS, I have always learnt to build upon existing information, i.e., summarise the existing information - identify the gaps and fill them. However, the approach in engineering research seemed totally different. Here they identified a(ny) problem, solved it, and then looked for supporting information! Well, I have had serious trouble because of these two different approaches in research - I was never able to accept there can be "non-hypothesis" driven research. However, a blog and a chat with a friend at CMU, made me go over the breakthroughs in Science.
Case 1: Newton sits down an apple tree. Apple falls. Newton discovers law of gravity.
Was there any hypothesis in this discovery? No! Newton first made an observation! He then went on to systematically study it and bingo - he derived the laws. So, there was a non-hypothesis driven research first - the observation that an apple fell. This was followed by hypothesis-driven research - "systematic" study of the observations. What one means by "systematic" is that, you pose a series of questions and check your logic of understanding by answering each of the questions with consistency. If consistency fails with your logic, you got to revise your logic - hypothesis. So, research involved a non-hypothesis driven observation followed by a hypothesis driven work.
Case 2: Structure of DNA is a double helix.
Crystallization was a new technique in the 1940's -50's. Watson and Crick were curious to know the structure of DNA, as many of the contemporary scientists were. So, they made an observation - the diffraction data - and interpreted them. While the interpretation involved asking a series of logical questions in order, they were, as such NOT addressing any hypothesis. So, again, this is a clear example of non-hypothesis driven + hypothesis driven research.
To finally conclude, research is both making an observation and studying it systematically.
In the context of Systems Biology, I guess the entire field is in the stage of non-hypothesis driven research. Not much progress has been into making meaning out of the observations generated so far. But with time, it shall see its fruits and enter into its second phase - hypothesis driven research.
PS: Just making a RANDOM observation is NOT Science. An observation that resulted out of curiosity or inquisitiveness is only Science. I will talk about Serendipity and Science in another post.

For the Structural Bio Enthusiast: Torsion Angles
In structural biology, I have come across the term torsion angle many a times. But I never understood the precise meaning of it until today! The motivation to learn about it came from Dr. Xian-Jun's blog: Torsion Angle
Dr. Xian-Jun had given a detailed description of how to calculate it, though he had taken for advantage that someone reading it will know what a torsion angle is - I did not know! A quick google search yielded some informative links. The summary of my learning is as follows: In the newman projection it is the angle between the bond that is nearer to you and the bond that is farther from you. A more clear explanation is given at IUPAC

Ancient and Unique Nature of Tamil
I have had small debates with my North Indian friends as to which Language (Tamil or Sanskrit) is the mother language of all Indian Languages. Naturally, they claim Sanskrit to be the oldest, and I claim Tamil to be the oldest. It perhaps seems that both are the oldest!! The below link shows evidences that Tamil developed with NO influence of Sanskrit.
Scroll down to "Origins of Tamil".
http://karkanirka.wordpress.com/2009/10/12/tamilintro1/
Also came across: http://www.ifih.org/SouthIndianInfluencesintheFarEast.htm
If you had read Kadal Pura, you would have already known that there was a huge South Indian influence in the Far East..if not, this site talks about it...I haven't read through it thoroughly...but I trust the source.

OBAMA FOR NOBEL PEACE?
It came as a very unexpected news that the US President Obama was voted for the Nobel Peace Prize for 2009. Though I knew not much of nominations and the criteria, I definitely did not, even in the slightest, think of Obama for Nobel. Anyway, I read up on the news in a few news papers and I understood that it was awarded to him for the claims and promises he made in his presidential campaign. There is a huge uproar and sarcasm against the Nobel committee which made this decision. However, I think I am going to support the school of thoughts which says, the award will compel him to bring his promises true. I don't know what Alfred Nobel originally stipulated as the requirements of the award. But I think it perfectly makes sense to put an extra pressure to a man who made tall claims by honoring him with the Nobel. At the same time, the money gives him the freedom and confidence to do what he desires to make the dreams come true. So, instead of awarding a person who has achieved already, the Nobel committee's decision to award a person who can potentially achieve the need of the hour is wise.

"To put it bluntly, the only thing that appears to have motivated large numbers of people to invest significant resources in science is fear of dying..."
Can layman be any longer ignorant of the scientific happenings around him? How important is to educate layman on Scientific pursuits? And a lot more questions on Science. David Balamuth analyzes each factor and answers an interview, the details can be viewed here

Well...well...there is something that I seriously understand:
Some people, who are supposedly in "good" and "high" positions...or atleast are in the path to that, cannot really take care of small stuffs! For example, maintaining stationary inventory, getting the requested quality of a product etc., seems so silly to them..but that makes a difference! When they canNOT pay attention to such small details, how are they going to make a difference with a "big" detail..and what good it would be to put them in a higher position?

Well, well...India and Indian people are never going to come out of their stupidity.
Would anyone compel their own daughter to marry someone whom she doesn't want to marry? Well, the daughter has not much choice! And you have to believe it! Arranged marriages can be good...but I guess with changing social life pattern, it is important to consider the preferences of both the individuals. I think this is quite important for the development of the society as well.

I just happened know that people can even be reluctant to visit a doctor, despite having some problems. Even if it were minor, if it were I, I wouldn't have let it and I would have got a consultation. However, Mr. X dismissed that since he didn't have anymore symptoms, he was fine. But I am not sure if this is right. The discomfort could have been due to many reasons, which a layman wouldn't suspect. Even if it was a simple problem, my advise would be to pay a visit to the doctor and get it confirmed that it was nothing. However, I learn that people are a bit reluctant because of the cost involved. The consultation fee, lab fee, prescription fee etc etc. That is true. But one cannot risk his life for money, especially when there is a whole 50-60 years of life ahead! Well, truly, I don't know what is right in this case!

Be True to Yourself
In light of women's day, there was this article (click here)that appeared in rediff where in an IAS officer, Mrs Ministhy Dileep had written an article on balancing work and life. It is a quite common plight that women give up jobs to take care of the kid - the larger good. However, isn't it also necessary to allow women to pursue their desires? Kids - a decision that has to be taken by both and the responsibility of raising the kids is on both the parents. However, in India, it has been customary for women to stop working after having kids. Is this voluntary or under compulsion, I don't know. However, I do think that women should be allowed to pursue their desires. At the same time, men should also be allowed to pursue their desires - if you don't want to go shopping - NO GO! Everyone should be allowed to be true to themselves.

Finally, the oscar buzz is over. ARR conferred with 2 oscars and every Indian is so proud about it. While every Indian MUST be proud of it, I just want the people to think WHY ARR won the oscar for Jai Ho and the other song. WHAT in Jai Ho made it really unique that it stood up the strict evaluations of the oscar committee? Shouldn't that be spelt out for other aspiring music directors? Would ARR or any other music critic do that for the benefit of others?
