Monologue: Ismat Appa ke Naam
The monologue was presented by Naseer, Ratna Pathak Shah i.e. his wife and Neeba shah, their daughter. It comprised of three short stories by Ismat Chugtai. Ismat Appa was an Indian Urdu writer known for her controversial and remarkable stories. The stories presented were "chui mui" i.e. Touch me Not, "Ghunghat" and "Gharwali". The stories were presented in an amazing manner, really. I attended a Monologue for the first time. I admired the story Ghunghat and most importantly admired the way Ratna Pathak Shah presented it to the audience. I had heard Ismat Chugtai's name earlier but didnt know much about her stories. In fact hadnt read them earlier. This story Ghunghat was really humorous but at the same time had a hidden sadness in it. If you actually sit back and analyze, it had a very tragic end. I just hope it was a fiction and not inspired by any real incidence. In short, this story depicted a guy who was a Mughal and had a black complexion (kaale mia), he got married to a very pretty and specifically a white-complexioned lady (called gori-be). His ego (false, obviously) got hurt on his wedding day after overhearing some remarks about kaale-mia getting married to gori-bi and so he didnt see his wife's face his entire life and at the end died when he was just about to see her.

The Mumbai Terror Attack!!!
Who was Sandeep Unnikrishnan? He was an Indian. Neither Maharastrian, North Indian nor South Indian. The 31 year old only-son of a retired ISRO officer. Unfortunately people will always remember who Raj Thackrey is but we will very soon forget who Sandeep Unnikrishnan was!! Heros are to be remembered only on a special day (26/11) but Raj Thackery will be a celebrity always, on news channels, in newspapers and in people's mind too!! Shame on us!!

Genetic tracing reveals a stereotyped sensory map in the olfactory cortex
Zhihua Zou, Lisa F. Horowitz, Jean-Pierre Montmayeur, Scott Snapper & Linda B. Buck
Nature 414, 173–179 (2001)
This Article described patterns of labelling observed in olfactory cortex when a transneuronal tracer was co-expressed with single odorant receptor genes in the mouse olfactory epithelium. During efforts to replicate and extend this work, we have been unable to reproduce the reported findings. Moreover, we have found inconsistencies between some of the figures and data published in the paper and the original data. We have therefore lost confidence in the reported conclusions. We regret any adverse consequences that may have resulted from the paper's publication.

Great Egypt!
!!Egypt!! It really fascinates me!! I just love to read anything about it and watch anything based upon it!!In the latest National Geographic magazine the main article features "Black Pharaohs" (http://ngm.nationalgeographic.com/ngm/hubs/latest-features.html). Pharaoh, according to Wikipedia is Egyptian word for king, but for a descriptive definition kindly check the Wikipedia!!
I really admire Egyptians, their idea about immortality, their ways of saying a final goodbye to their Kings and Queens, it really amazes me!!
This bottle of perfume e.g. was found in one of the cemeteries as a gift to one of its King and this amazingly carved pendent (above) designed for a goddess are clearly evident of their values and rich and different culture!!
The first king of Egypt mentioned by name in the Bible is Shishaq, the title pharaoh is prefixed to his name in the Great Dakhla stela—as in Pharaoh Shoshenq—which dates to Year 5 of his reign.
Although over the world wide net there are several ways Pharaohs have been defined.
"http://www.touregypt.net/magazine/masterindex.htm" This is a good website that talks about the history of Egypt and much more!!

Shiksha Sopan Annual Program
Day & Date : 13th Jan,08 a Beautiful and sunny Sunday.
Event : Shiksha Sopan Annual function by small kids
Place : The GPN Mahavidyalaya, Barasirohi, Kanpur.
Shiksha Sopan was started in 2001 by a bunch of IITK students in order to impart education to the children in the nearby villages, Barasirohi village being one of them. I have joined this group recently and I try to go to one of these centers once a week (although not a very significant amount of time). The kids who generally come to this center includes those who are a regular school-goer and those who are not! There are children of various age groups. I think it ranges from 4-15yrs. I am especially inclined towards the smaller age group, reason being, their innocence, their questions which come without any hesitation, their freedom to show their liking for others, for example one day a small girl simply came over and told me that she likes me a lot. She is very sweet too! I am not being biased but she 'radiates' innocence, really!!
So that Sunday they were all prepared and decked up for the annual function. There were many group dance, drama, fashion show and the occasion was graced by Prof. S Khandekar and his PhD supervisor from Germany. The dramas were very nicely presented on common social issues. It was really great to see small children giving such big messages to the society on social issues.
Great experience for me and a lovely bright Sunday.

Science retracts major Arabidopsis paper
Four out of five authors of a Science paper that the journal called a "breakthrough of the year" in 2005 have retracted it, saying that the data it was based on could not be replicated.
The study, which described the migration of mRNA to initiate flowering, was based on real-time PCR data, which researchers in the Ume￥ Plant Science Center lab where it had been performed found impossible to replicate. According to principle investigator Ove Nilsson, first author Tao Huang had manipulated data, removing certain points and giving increased weight to others.
Huang, the only author not to agree to the retraction, maintains that the data omissions were valid and documented. "Although I can understand and respect Professor Ove Nilsson... I think the retraction for this paper should not happen, [and was] at least immature," Hwang wrote in an E-mail to The Scientist.
The work has been cited in 54 papers according to the ISI Web of Science. "To some extent, some may have been misled," Takashi Araki, a professor at Kyoto University wrote in an E-mail to The Scientist.
"Obviously these have been very difficult times for me and my group," said Nilsson, "And of course, it's a big set-back for the Arabidposis part of our research." But he says his lab has continued to publish on flowering in trees, and found no errors in other subsequent papers. "People realize that we have handled this according to the books. We had discovered this ourselves and we took the necessary steps to correct it," Nilsson said.
For 70 years scientists have known that a signal, the so called florigen, travels from the leaves, which detect such changes as temperature and day-length, to the growing tip of the plant where it initiates flowering, but they hadn't known what that agent was. In August 2005, Huang et al. reported that mRNA of the flowering locus T, or FT gene, travels to the tips, where it is transcribed into FT protein to signal flowering.
When the paper came out, it was well received. Other studies had already shown that plants used RNA in signaling, so when the paper emerged implicating the FT mRNA as a moving element "it was not that surprising," said Brian Ayre a plant biologist at the University of North Texas. But, he said, this retraction could cause a bit of backpeddling for some in the field, since the FT mRNA theory had already made it into several prominent plant textbooks.
Araki said that he and his group were suspicious of the finding when it was first published in part because his group's results showed that the FT protein, rather than mRNA was actually the moving element and partly because of "very small statistical errors in their real-time PCR data," he said. He also mentioned that "the paper seemed to fit too well with the popular textbook knowledge."
Two papers published online in Science this week, one authored by Laurent Corbesier et al, at the Max Planck Institute for Plant Breeding Research, and another by a Shojiro Tamaki et al, from the Nara Institute of Science and Technology in Japan, indeed indicate that the elusive florigen is the protein product of the FT gene, rather than mRNA. Corbesier's work in Arabidopsis and Tamaki's work in rice both bolster previous work in tomatoes which did not find mRNA, and implicated the potential use of proteins, published in the Proceedings of the National Academy of Sciences by Eliezer Lifschitz.
Nilsson told The Scientist he first discovered an anomaly after Huang, a visiting scientist, left his lab to return to China this past September. Another student and a postdoc, wishing to continue Huang's work found data points marked in red that had been removed from the final analysis. Nilsson's lab was unable to reproduce the data and contacted Ume￥ University which resulted in both an internal and external investigation.
Huang said the removed data points were "irrelevant to the experiment," because variable temperatures of a heating plate rendered certain data points invalid. He said he had circulated his results for review, with the anomalous data points marked in red, before he left the lab. He wrote in an E-mail, "None of my fellow labmates thought it was improper to exclude those irrelevant samples at that time." He also mentioned that he had not been contacted by members of the external investigation.
Lars Rask, a professor at the University of Uppsala who was one of the two people who conducted the external evaluation, confirmed that Huang was not interviewed. Instead, the committee evaluated correspondence between Huang and Nilsson after Huang's departure. In an E-mail to The Scientist, Rask wrote, "As far as we could tell from the E-mails, [Huang] realized that there were potential problems in the experiments carried out."
Despite the controversy surrounding Huang's research, the field as a whole may not be tremendously affected. The original Huang paper had not discounted the possibility of an FT protein playing a role. "That left the door wide open," said Colin Turnbull, a co-author of the Corbesier paper. "All we're trying to do as a community is move forward. And FT is definitely important and the fact that it's a protein is just as exciting as if it had been RNA," he said.

Rare Thingy here!!
Although 'Plans' do not materialize but sudden thoughts do!! The scene is: some of us are sitting in fac lounge and having tea, time is around 12:30hrs and we are all dying to have good cake (certainly not from ShopC if the condition of "good" is attached).
Suddenly somebody floats the idea of going to Globus again on the same evening!! Some other, floats another "fundoo" idea of making it "right now". Well RIGHT NOW!!! LUNCH and CAKE!!
And the rare thingy is "we all are ready". Ready to leave our quotidians for a day!! Out here!! In Kanpur!! Really a Rare Phenomena it is, believe me :)
We hired a 'Vikram'!!
More later, have some work right now!!! :))
