Nobel Prize Week: Days One and Two

Congratulations to Mario Capecchi, Sir Martin Evans, and Oliver Smithies for each winning 1/3rd of the Nobel Prize in Physiology or Medicine 2007 “for their discoveries of principles for introducing specific gene modifications in mice by the use of embryonic stem cells,” meaning this research allows for the production of genetically-modified mice, and gene-targeting, which has opened the door to understanding what specific genes in the mouse genome do by “knocking out” the genes. 10,000 mouse genes have been knocked out so far. This research, which has been going on for nearly 30 years now, sets the foundation for identifying the genes behind human diseases, targeting them, and one day straining them out of our genome.

Breakdown of this important research here.

Also, from the Scientist who made the above mouse, Shan Maika, when I requested permission to use this photo:

this mouse embryo was the result of crossing a transgenic mouse I made here at my facility (S100-rtTA) with a Tet-On/Lac Z mouse and then administering doxycycline (in the drinking water) to the mother during gestation. Below is what the student sent me when he gave me the picture to use on the website.

The LacZ transgene expressed in Schwann cells and visualized via histochemnistry for beta-galactosidase. We used the S100B-promoter (a glial selective promoter) to drive the expression of the reverse transcription Trans-activator (rtTA). Because this system is base on the Tet-On conditional gene expression system (Fruth et al., 1996….I think)all I have to do is feed these animals tetracycline or one of its derivatives (ie Doxycycline) to activate transcription of LacZ in the Schwann cells.

Congratulations to Albert Fert and Peter Grunberg for each winning 1/2 of the “for the discovery of Giant Magnetoresistance.” Regarded as one of the first major applications of nanotechnology, and was a crucial discovery in the development of smaller and smaller data-storage:

…the ongoing IT-revolution depends on an intricate interplay between fundamental scientific progress and technical fine tuning. This is just what the Nobel Prize in Physics for the year 2007 is about.

An entry-level explanation of the discoveries here (PDF).

A more technical explanation here (PDF).


The fact that nobel prizes seem to be going more and more to several people working on the same research is a symptom of how complex progress has become. Fading away are the days of lone inventors and scientists revolutionizing a field single-handedly. The Great Man Theory was always an overly-simplistic view of human history, and one that has given people distorted views of their place in society. I have seen the future, and it is wiki-style collaborations. One day the Nobel prize in Physics will be split sixteen ways.

In the Shadow of the Moon

Tuesday, October 9th, 2007
Naro Cinema

Got to check out this inspiring documentary last week, just in time for the 50th anniversary of Sputnik 1. The film wisely skips the Cold War dimensions of the Space Race, an historical context today’s generation can’t really relate to, and probably shouldn’t bother to considering the U.S.S.R. turned out to be a paper tiger. Instead, the focus is on the wonder of space flight, its novelty and how it influenced American 60s culture and briefly made all countries one world.

The film also brought out a number of details I was unaware of surrounding the Apollo program. For instance, I never knew atheist leader Madalyn Murray O’Hair sued the Apollo 8 astronauts for reading aloud from Genesis during their mission. Or that a programming error “1202 program alarm” jeopardized the mission as the computer was unable to process both the landing and rendezvous data simultaneously and crashed.

In the event that the astronauts were unable to leave the Moon, Nixon was to read a contingency speech, which begins, “Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace.” The rest of it is pretty inspiring too.

Equally inspiring is Buzz Aldrin’s admission that on his way down the ladder to take his first steps on the Moon, he paused for a moment to alleviate his bladder, a moment immortalized in this photo.
