  1. Globally a lot of people eat rice as a part of their staple food. I have felt that I feel sleepy after consuming rice. I have personally observed this and a lot of peoples views have confirmed the same.

     

    Can anyone please throw light on this ...

    1. What (factors) in rice induces sleep?
    2. Is the variety/quality of rice linked to this? Has it been scientifically proven?
    3. Does the glycemic load/glycemic index of rice play a role in triggering sleep?
    4. What is the mechanism of action of factor(s) that induce sleep?
    5. Does the brain need to concentrate on digestion of rice and switches off the other signals which make us lethargic?

    Please help me uncover the mystery behind this :confused:

    Any nutritionists, physicians, dieticians ....

  2. Before you worry about some disease, just from the above statement I would think that stress is an underlying cause. I think it is possible to work 14 hours a day, but only 5 hours of sleep is not enough. Your body needs to recharge, and the stress from only 5 hours a night every night has got to be taxing.

     

    I know stress could be one of the factors,but then why does it not affect any other ppl who also follow similar lifestyles. Also, it is not worrying me but that I want to know what could be a scientific reason for this. I contacted a physician too,but he told me that could be also due to frequent change in weather conditions. I work in around 10-11C while the outside temp is over 38degrees generally. But I was unable to comprehend this.

  3. I have been experiencing a peculiar problem for the past 8-10 months.

    When i get up in the morning, I find that a lot of hair from my eyebrows and eyelashes fall. This was less initially but it has increased recently and today there were about 11-12 hairs, which i noticed while washing my face.:mad:

    I am just 27 & athletic body type,is it natural to have this or there could be some underlying reasons? I sleep about 5 hrs a day and work over 14 hrs!

     

    Could it be because of deficiency of vitamins, minerals etc or just less of sleep? Please explain.:confused:

  4. here's what I got from a quick search:

     

    Synthetic biology is a new area of research that combines science and engineering in order to design and build novel biological functions and systems. There are four main branches of research that define the field: Biology, Chemistry, Engineering, and Re-writing.

    http://en.wikipedia.org/wiki/Synthetic_biology

     

    What is Synthetic Biology?

    Natural biological systems process information, materials, and energy. Our understanding of these systems is rapidly advancing. Unfortunately our ability to use biology as a technology to process information, materials, and energy as we desire is limited by our understanding. To circumvent these limits, a field of study is emerging based on intentional engineering of biological systems.This Synthetic Biology is focused on the intentional design of artificial biological systems, rather than on the understanding of natural biology. It builds on our current understanding while simplifying some of the complex interactions characteristic of natural biology.

     

    Relevant Research Areas

    (all topics areas have an implicit requirement of being biological in some fashion)

    Biochemical or genetic network design

    Energy sources

    Parts fabrication, characterization, assembly

    Network analysis

    Biomaterials

    Biomimetics

    Computation using biological components

    Design principles of systems and networks

    Device physics

    Directed evolution and evolutionary optimization strategies

    Information processing and control theory

    Microfluidics

    Molecular machines

    Modeling of synthetic systems

    Noise in systems and components

    Organism engineering

    Programmable organisms or systems

    Protein engineering

    Quantitative measurement techniques

    Reporters

    Sensors and actuators

    Single molecule manipulation and/or measurement methods

     

    Please consider this list as only a guideline for areas pertinent to Synthetic Biology. As this is an emerging field, there are likely many research fields of interest to this community that are not listed here. Similarly there are many research areas that may fall under these topics but are not pertinent to the goals of Synthetic Biology.

  5. Matt, I have gone thru this exhaustive article(on the link).I have understood most part of the paper, but am unable to decide where to start and how will the initial data look like(data, values, format of data, file format etc). Also, I have looked at the equations discussed, where by eq(6) is the most appropriate and will give the proton-deuterium exchange. This gives us which AA are around the boundary and which are inside the core of protein.

    But we could also get the hydrophobic and hydrophilic AA from the seuence itself and move on those lines? But how will this value help us predict the structure of protein? The higher value depicts the alpha-helix, but this is only for Cyt c and how can this be generalised ?(what threshold value shud be taken?)

    Plz help me further on this. I am really looking forward to this project now.

  6. Matt,

    That was a bit tough to get, can u please discuss more of it. I don't think I have got what u really wanted to put through.

    let me tell what I got from that, we want to predict the tertiary struc when the protein is in solvent(water) and the c-alpha and nearest H20 distances are known. Does it mean that we have to gather the water and C interactions and steric energy and get the tert struc in a minimum energy level in solvent??

    if so, can u please exemplify it more, or if not then please put forward in very basic terminology, so that it makes more sense to me.

  7. Hi friends,

     

    Calling all bioinformaticians to help me! I have to make a project using the bioinformatics tools. Can anyone please suggest what could be the best topic foe me to pursue at grad studies?

    I have to develop a tool(program) to do some basic BI calculation/simulations /interpretations that can achieve a desired level of result. I have already done a project on the analysis of Microarray data, so I am inclined towards Proteomics/Protein Chemistry, but is open to any good research topic.

     

    Can some people help me describe some good projects that could be done(at grad lvl). Please give relevant details on the data availability and conclusions that could be drawn at the end with some reference to the procedure/algorithm adopted. I will be grateful to all and he/she will definitely get a mention in the final project/ thesis.

    Some broad areas that I am aware of are :

    • Microarray data analysis
    • Comparing genomic sequences using Dotplots
    • Computational Evolutinary genomics
    • Protein Structure Prediction etc.

     

    Please help me out with as diverse projects as possible and it would be great if anyone could help me with a current/live project.

  8. This is perfectly fine as Equivalence Point is defined as the point where the solution exhibits pH neutrality(7.0) and they are mixed in exact quantities. If u increase the volume of acid then there would be a simultaneous increase in the protons and hence more number of base ions would be reqd to neutralize it. This is true only if the volume is changed and not the strength of the acids/bases.

  9. i've always pretty much assumed i'd be a scientist. I don't ever recall finding science' date=' i think i was born with it:-p

     

    when i was 7 or so they asked me what i wanted to be when i grew up. I said scientist and i've stayed with that.[/quote']

     

    ditto here!! I was introduced to science when I was bit older about 11-12 yrs. The unknown areas of science and my will to contribute to it has effectively guided me to burn myself for science. The unending desires of knowing to what is unknown and explore to reason it out has been the unending motivation.

     

    Now I know I was made for science and will even die contributing to science and its development. I was introduced to chemistry and it just pulled me in. The next major blow when the unexplored biology struck me in the face and was attracted to the molecular biology and bioinformatics challenges. Since then I have tried to build up my knowledge on scince and have just realised that this one life is still insufficient to be aware of only one field of science.

     

    I may not be another Einstein or Heisenberg but I will prove my scientific worth one day !!

  10. Could you go to http://virusscan.jotti.org/ and upload the file E:\WINNT\system32\myproxy.exe[/b'] and copy/paste the results of the jottiscan into this thread please.

     

    I cannot find any file as above in my system

     

    Can you also confirm that you recognise either 'Sify Broadband' and/or 'Value Added Network service provider in India' as your internet service provider?

    yes Sify Broadband is my ISP.:)

     

    What do I do next? Any other file that I may upload to virusscan....??

  11. thanks Dak!:)

    here are the log files of Hijackthis and Scanspyware. One more thing that I noticed is that even when I am offline the new ad pages keep on poping up!!:mad:

    Can u please help:confused:

  13. Hi,

    While my PC was online which is generally(due to Google Folding!:) ), my computer just got a new problem. There are popup windows/webpages that link to advertising wesites and adwares.

    They also removed the installed Google Toolbar. Now when ever I open a new page i am redirected to another page and this happens even while a site is open. I have tried the 'scanspyware' 'Spybot S&D' 'Hijackthis' and 'Ad-Aware' tools but it does'nt help!!:mad:

     

    Can anyone helpme with this asap?:confused:

  14. NASA faced a problem that fountain pens that were used during their space program couldn't be used because of no gravity. So they wasted millions of dollars n two decades to overcome d problem.But Russians solved it in d cheapest way.Guess what.

     

     

    they used a PENCIL !!:D

  15. Hi All,

     

    I want to pursue my PhD in Bioinformatics, but I am still dicey about the place to study in US. There are many places where the prog is running but I don't know which one is good. Can anyone help?

     

    Also, how good are the job prospects after a doc in bioinformatics? I have a lot of enthusiasm and willingness to work in the field, but the dearth of resources in India on the subject, does not allow me to do it. I am an MBA with a Masters in Bioinformatics and a Masters in Chemistry as well.

    Can someone please answer??

    You realize there's powerful motivation to get educated, in places like India and China. Without a higher education, survival is real tough - and that's a darn good reason to get your @$$ into school. With no college degree, you can't hope for a whole lot more than a position of an unskilled laborer. And in these countries, labor is very cheap, even by the local standards. An unskilled laborer lives very close to the poverty line.

    [/quote']

     

     

    In India, more than 85% of the educated are undergrads or graduates with some or the other professionals courses like Accounting, MBA, R&D etc. It is not just the sheer number but the will to study and compete with the world and come out victorious. The challenge is not just to earn a college grad or post grad but to increase their knowledge at par with what an American does during his lifetime !!

     

    The labour in India & china is not cheap it's just in the competitive environment.

  17. I am a bioinformatician. The love of biology and passion of computers made their marriage possible for me. It is a tough choice but a real fighter loves challenges and makes things work for him.

    I have a Masters both in Chemistry & Bioinformatics, but when deciphering what life holds in it(still a mystery) is really fascinating !!
