After 19 days... Jackson still going strong in charts

I was checking out this week's last.fm chart, Micheal Jackson at the top: expected. But the way he was leading... most loved, top artist, top track, even in hyped track (some of the less famous tracks of Michael)... hyped artist included Jacksons and Michael's brother Jermaine!

10 Apple top album includes 3 Michael ones!

19 days and still leading all the charts, I don't buy the conspiracy theories, but at least Michael's sister La Toya Jackson is literally right, "He was worth more dead than alive."

Nature, Science and Michael...

It has been a long day :p Slept a lot, the only productive part of it was going through the current issues of Nature (Volume 459 Number 7250 pp1033-1160) and Science (Volume 324 Number 5935 pp1603-1754).

If you're reading Nature or Science, definitely you're going to find something interesting, no matter what is your taste or interest. Anyway, to me, current issues of both of the journal lacked the usual glamour, generally I cant pick my clear favourate. One article in Science really caught my attention, the group assayed DNA-Protein interaction of ~100 mice Transcription Factor (TF) DNA Binding Domain (DBD); Vol 324 p 1720. Another paper on formation of functional centromere by synthetic heterochromatin was worth mentioning; Vol 324, p 1716.

Nature was slightly better, there were three articles on science journalsim which I thought worth reading; Vol 459, pp 1054-1057. The research article on membrane fusion (p 1091) and correlation between transcription and DNA replicatio fidelity (p 1150) was quite interesting. But I thought the paper on role of mechanical force generated by the first cardiac pump in embryonic haematopoesis is a masterpiece (p 1131).

Last but not least, I woke up this morning and my brother gave me this bad news: The King of Pop Michael Jackson died of cardiac arrest. The news was really a saddening one, but we all have to die at some point of time.

Heal the world... Make it a better place... for you and for me and for the entire human race... RIP Michael.

DST from my perspective

The country is clearly another step ahead by using DST, Daylight Saving Time, from tonight. I wont go for justifications (one of my friend, Minhaz seriously doubts its any positive effect and he put forward lots of geographical explanations, lets not go to that.)

What I felt is the government failed to publicize it. Its now just a high class educated society clock time change phenomenon, rather than being an event of mass participation. I can give an example form my own life. The guard at our house today refused to open the gate at 7 am, he was insisting the gate will be opened at 7 but now its only 6 am. My brother, to his utter annoyance, failed to convince him that 7 is 7 and all the offices, schools, colleges and universities will start according to the new time schedule.

But the fact is, I'm not surprized at all, its the way things work in our beloved country. We have some highly talented individuals at the administration who execute their decisions without even the need of planning, let alone the concept of proper planning. Its ridiculous to start DST when technically we have already finished summer and on the brink of the longest day of the year (21st June, DST should be evenly distributed at the both side of the longest day, i.e. if DST is in operation for two months, one should be before the longest day, the rest should be after it).

Hail us and our leaders...

Catching Cold by reading New Scientist !!!

Theoritically right now I should not be writing blogs, I should have been checking different universities or taking rest :p

Anyway, couple of days back I was reading this article on Common Cold in New Scientist I brought from British Council. It was kind of interesting. Three suggestions were there if you want to avoid cold (don't sue me if you still catch cold):

  1. Avoid direct contact with children, they are miserably efficient in transmitting viruses.
  2. Avoid having cold feet, I'm not quite sure how this works, but I think the mechanism is if your feet is cold, the blood flow is directed to feet reducing the flow at the nose, thus reduced immunity! (No reference please, I'm not quite sure about the mechanism myself)
  3. Finally, wash your hand regularly. In case you shake your hand with a person who has cold, you can also catch! Wash them, be safe :)
The funny thing is after reading the article, I wasn't feeling that much good! The very next day I caught cold! Is there any mechanism of catching cold by reading New Scientist article on Common Cold :p

Scientific or Promotional!!!

Today a scientific conferance on Promotion of Biotechnology in Bangladesh: National and International Perspective has started at Sasaka Auditorium, ICDDR,B. The official URL for the conferance is

http://www.promotebiotechbd.net/index.htm

I was going through the conference schedule and related stuffs. My first reaction was, "Actually what is the purpose of arranging this conference?"

Its not a scientific conference. Most of the papers and posters going to be presented are already published stuffs!

A conference to promote biotechnology? Neither. In fact it will do even worse if this is the purpose. Only 300 restricted participants... inside a closed auditorium... no interaction with general people.

Another thing irked me. There is a cultural function session! Doesn't make any sense. To make things even worse Shuvro Dev has been paid Tk. 50000 to perform. Waste of invaluable money and time. You don't need cultural functions in scientific conference...

Bangladesh is a weird country with strange peoples! A conference has been arranged for the sake of arranging a conference... no goal, no objective...

Dream or Myth

BAS told not to disclose to anyone.

He thinks he knows someone who can cure cancer ... any type !!!

A dream or A myth!!!

Well, lets wait and see ;)

12 hours and your cancer is cured!


Sometimes life is really tough. This entry was supposed to be in last Monday or Tuesday...

It's BAS. (Baizid Alam Shibib)

Last Monday, he came to the class and started day dreaming ;)

He was asking,"If someone from Bangladesh invents a drug which cures any type of cancer within 12 hours, will s/he get Nobel Prize?" I said,"Not once..."

How can a biochemist have such fantasy? When I told Tanaeem, he laughed and said,"This joker has no idea. Complications like cancer; curing in 12 hour! It is not a disease. You can't go and kill the pathogens! It's your cells dividing uncontrollably and bringing back the control requires hack of a time!!! At least couple of months, in fact years."

He could have increased his credibility! He could have said any particular cancer, may be in a month or 6 months... that would have made lot sense. All cancer! He has no idea how cancer forms. There are at least millions of ways: activation of oncogene, inactivation of tumor suppressor genes... non-functional cell signaling... mutation ... I don't think the list will ever end. And if someone says, he wants to treat all these with one and only drug (when I can't even list them in single sentence), then I guess he has problem in grasping the difference between cancer and other diseases... funny thing is he teaches Human Physiology in Department of Biochemistry. To add to the surprise list, Biochemistry students think he is the moving encyclopedia!!! Ha Ha Ha!

May be he meant Astrology's Cancer ;)

A Brand New No and Puzzled SRK

Today's Topic: SRK. (For those who don't know, SRK stands for Sanchita Rahnuma Khan.)

Yesterday she was taking class on Horizontal Gene transfer between bacterial species, especially Transduction. As an intro she mentioned Zinder & Lederberg experiment. She told, in the experiment observed frequency of gene transfer between two auxotrophs were 10-5. Anyway, she continued with her lecture. In the class I came to know following facts:

Firstly, the frequency of DNA transfer from bacterial genome to phage genome is 1-2 %.

Secondly, the frequency of DNA transfer from phage to another bacteria is 1-2%.

Taking these facts together, my calculation was the frequency of gene transfer would be 10-4. The 10X anomaly can be explained if we consider the fact that each DNA transfer might not result in complete Gene transfer. But she gave another brand new data!!! She said, the frequency of gene transfer by transduction is around 10-6. This was completely unexpected. I was wondering to solve the mystery of 10-4 and 10-5, instead a new data of 10-6 came up. I was completely puzzled and brought the facts into her notice. To be honest, I asked her out of curiosity, I didn't mean to harass her. (If you are a teacher, I think you would prefer not to have me in your class ;). Cause I can create lots of troubles when I want to, and sometimes I do.) Felt sorry looking at her face and I myself tried to cover up things by answering from my instincts. Anyway, she told us to check things out.

I've downloaded Zinder & Lederberg's paper, read couple of pages. The paper is kind of clumsy, but I think I'll be able to figure it out...

Lamark and AAA

It's AAA today ;)

He was taking developmental biology. Nothing new, same old Triple A style. Suddenly I was stunned hearing some of his words!!! Was I hearing right? He said, memory is an important attribute in higher organism's cell... kind of Ok so far. Afterwards, as an example he said, experience from parents are passed to their offspring through cells. Gosh! Am I in 21st century? How can someone advocate Lamarkism which died in 19th century Darwinian Era? I should have argued with Akandh Sir. It's the old habit. I know there is no point. Critical thinking isn't appreciated in this failed educational system. Hail Memory! That's the only slogan here.

Another analogy which he wanted to draw appeared bit absurd to me. He said a shoe and an aeroplane manufacturing factory doesn't use the same material and technology. Likewise biologists expected distinct variation when they studied development of different multicellular organisms... but they were surprised to see the extent of similarity. Well, shoe and aeroplane are completely different things, their difference isn't even analogous to the difference between prokaryotes and eukaryotes. If he compared the production strategy of car and aeroplane, I think he would have found lots of similarities. The apparent similarity is at the same time a fascinating and a frustrating thing. Fascinating because it shows us the fundamental similarity, while it's frustrating because it testifies the fact that there are lots of to be discovered stuffs.

Meiosis: Who knows, me or DJ?

Net connection is awesome today.

I thought there was no DJ today, became surprised to see it was in the routine.

Today she discussed sex determination, chromosome, chromatin fibre, mitosis and meiosis. A question came in my mind when DJ was delivering her lecture. Why X and Y chromosome's are named so? I googled net and found the answer from Google books.

Q: Why X & Y chromosomes are named so?

Ans: A common misconception about X and Y chromosome is that they are named because of their shape. However, Hermann Henking named the X because it was mysterious, or exceptional in some way and that Nettie Stevens then simply continued the alphabetical sequence when she named the Y.

(Source: The X in Sex: How the X Chromosome Controls Our Lives By David. Bainbridge)

When DJ started mitosis and meiosis, I got confused whether she knows those terms or not?

Life starts through meiosis, after fusion of egg and sperm!!! I don't get any of this, especially when she is saying about Homo sapiens. (Her words are correct for haploid organisms who undergo meiosis when diploid zygote is formed.) I've to wait and see.

(Right click and open in new window or tab to view enlarged image)


Another confusion arose when she asked, "What is the difference between Chromatin fibre and Chromosome?" Different answers came from different corners. I think some of them were right, though weren't complete. Chromatin fibre is non-condensed string of nucleosome which divides and condenses before cell division. This condensed form of chromatin fibre is known as chromosome. (Appears H shape in typical karyotype). Anyway, DJ rejected them. Instead she accepted Maruf's lead (partially) which I found the least appropriate.

She also talked about Genetic Maps. I know there are three types of maps, but right now, I can't recollect.

Ignorance Vs Truth


I am shocked!!!! This is a victory of ignorance and bureaucracy over truth. I am amazed to see the naturte of allegation; 7 years back... I've enough doubt whether the development of genetic engineering was as advanced to engineer HIV virus!!!- That's what the lawers of the patients said. Funny logic indeed.

Initially Libya contacted Luc Montagnier, the co-discoverer of HIV virus, to conduct inspection of the mass outbreak of AIDS. Luc Montagnier's report cleared the Palesteinian Doctor and Bulgarian Nurses, instead he accused dirty condition of the Libyan Hospital (which is considered one of the best there). Libyan court rejected the report citing the report contradicted Libyan doctor's initial report. - What an idiotic reason behind rejecting!!!

There is still an option of appeal. Hope the court will uphold Justice....

Below goes the news from Yahooo News:


Libya sentences Bulgaria nurses to death


By KHALED EL-DEEB and WILLA THAYER, Associated Press Writers

TRIPOLI, Libya - Five Bulgarian nurses and a Palestinian doctor were convicted and sentenced to death by a Libyan court Tuesday on charges they deliberately infected hundreds of children with the
AIDS virus. The verdict can be appealed.

Judge Mahmoud Hawissa read out the verdict at a seven-minute hearing in a Tripoli court at the end of the defendants' second trial.

The six defendants, detained for nearly seven years, had previously been convicted and condemned to death, but Libyan judges granted them a retrial after international protests over the fairness of the proceedings. Bulgaria contends the children were infected by unsanitary practices at their Libyan hospital.

An international legal observer, Francois Cantier of Lawyers Without Borders, criticized the retrial as lacking scientific rigor. Research published this month said samples from the infected children showed their viruses were contracted before the six defendants started working at the hospital in question.

"We need scientific evidence. It is a medical issue, not only a judicial one," Cantier said after the verdict.

The long trial of the six foreign medical workers has become a bone of contention in Libyan leader Moammar Gadhafi's efforts to rebuild ties with the West. Europe and the United States have called for their release, indicating that future relations with Libya would be affected by Tuesday's verdict.

But Libyans strongly supported a conviction. Some 50 relatives of the infected children — about 50 of whom have already died of AIDS — waited outside the court early Tuesday morning, holding poster-sized pictures of their children and bearing placards that read "Death for the children killers" and "
HIV made in Bulgaria."

When the Supreme Court ordered a retrial in December 2005, friends and relatives rioted in Benghazi, the Libyan city where the children were infected in a state hospital.

Bulgarians will no doubt be disappointed by Tuesday's verdict. Hundreds of people staged peaceful protests in support of the five nurses in Bulgaria on Monday.

Europe, the United States and international rights groups have accused Libya of prosecuting the six foreign staff as scapegoats for dirty conditions at the Benghazi children's hospital.

Luc Montagnier — the French doctor who was a co-discoverer of HIV — testified in the first trial that the virus was active in the hospital before the Bulgarian nurses began their contracts there in 1998.

More evidence for that argument surfaced on Dec. 6 — too late to be submitted in court — when Nature magazine published an analysis of HIV and hepatitis virus samples from the children.

Using changes in the genetic information of HIV over time as a "molecular clock," the analysts concluded that the virus was contracted before the six defendants arrived at the hospital — perhaps even three years before.

Idriss Lagha, the president of a group representing the victims, rejected the Nature article, telling a news conference in London on Monday that the nurses had infected the children with a "genetically engineered" virus. He accused them as doing so for research on behalf of foreign intelligence agencies.

When the defendants were allowed to give evidence last month, they denied intentionally infecting children.

"No doctor or nurse would dare commit such a dreadful crime," said nurse Cristiana Valcheva, adding that she sympathized with the victims and their families.

A second Bulgarian, Valentina Siropulo, testified that of her seven years in Libya, "I've spent only 6 months working as a nurse and the rest of the time in prison."

Gadhafi, who has been trying to refashion his image from leader of a rogue state, got his government to ask Bulgaria to pay compensation to the children's families.

But Sofia rejected the idea as indicating an admission of the nurses' guilt.

Missing Communication

Last night, I was going through pages of Plant Physiology by Ross & Salisbury. I came up with a box entitled “Must We Write? by Page W Morgan. The objective was why and how to write? It was in interesting comprehension in terms of both content and purpose.

It’s not surprising to me when I found the box stating that most of the science students find writing and communicating rather a useless time spending (which view I used to hold as well ;)). He put down some arguments against this. I think he was quite clear in his points.

I don’t like verbal communication with lots of people in general. But not sure what would be my attitude if the subject of communication is unknown to most of the listeners (Somehow I’ve the feeling that I will enjoy then.) But writing stuffs was never that irritating and boring to me.

Reading that article, I felt we miss one thing badly here in Bangladesh. It’s the lack of opportunities in developing communicating skills. There isn’t much we can do as students. In our department, DJ is trying to do something new. But I don’t like her approach. Anyway, everyone has his/her own style. We must learn to respect others. That’s one of the things we all have to learn.
