DNA From The Beginning Cracking the Code of Life Cracking the Code of Life PBS Airdate: April 17, 2001 ROBERT KRULWICH: When I look at this—and these are the three billion chemical letters, instructions for a human being—my eyes glaze over. ERIC LANDER (Whitehead Institute/MIT): The genome is a storybook that's been edited for a couple billion years. ROBERT KRULWICH: This is the story of one of the greatest scientific adventures ever, and at the heart of it is a small, very powerful molecule, DNA. For the past ten years, scientists all over the world have been painstakingly trying to read the tiny instructions buried inside our DNA. J. FRANCIS COLLINS (National Human Genome Research Institute): This is the ultimate imaginable thing that one could do scientifically...is to go and look at our own instruction book and then try to figure out what it's telling us. ROBERT KRULWICH: And what it's telling us is so surprising and so strange and so unexpected. ERIC LANDER: How different are you from a banana? ERIC LANDER: You may feel different...

In some genes the protein-coding sections of the DNA ("exons") are interrupted by non-coding regions ("introns"). RNA splicing removes the introns from pre mRNA to produce the final set of instructions for the protein. Transcript: As DNA is transcribed into RNA it needs to be edited to remove non-coding regions, or introns, shown in green. RNA splicing begins with assembly of helper proteins at the intron/exon borders. This process is repeated for every intron in the RNA.
Genes to Cognition Online DNA from the Beginning - An animated primer of 75 experiments that made modern genetics. Lab 2 - Analysis of Affymetrix Microarray Data James Wettenhall. Created June 25, 2004. Updated July 2, 2004. Contents: 1. Software required for this lab. You will need R 1.9.0 or later ( for this lab exercise. 1.1 Required R packages It is highly desirable to have these R packages in a directory in which you have write permission, especially for the estrogen package. 1.2 Recommended R packages 1.3 Required data files The Estrogen data set is listed in the Required R packages section. 2. For this lab, we will use data from a set of eight Affymetrix chips from a 2x2 factorial-design experiment designed to measure changes in gene expression in a breast-cancer cell line due to the presence (or absence) of estrogen and due to a time effect (10 hours or 48 hours). This data set is described in detail in the "Estrogen 2x2 Factorial Design" vignette by Denise Scholtens and Robert Gentleman [2]. The following description of the experiment is taken from that vignette. Experimental Data 3. 3.2 Preparing the RNA Targets file
Comment les médias sociaux stimulent ma mémoire ( Jean Guitton ) La mémoire, malheureusement, ne se commande pas. Il faut reconnaître notre faible empire sur cette contrée de l’intelligence. Au mieux réussit-on à cultiver aléatoirement certains souvenirs. On ne passe pas son temps, après tout, à déterminer ce que nous retenons, sauf peut-être l’école dans son déterminisme. La nature ne nous accorde pas ce pouvoir de décision. En amont de la pensée, le cerveau réagit principalement à des stimuli. Il aura fallu une requête de Gael Plantin , toujours pénétrant, pour susciter la réflexion sur ma méthode : D’emblée, je lui ai répondu : Poursuivant la réflexion, je constate que ces nombreuses itérations donnent lieu à une sorte de répétition espacée ([ 1 ], [ 2 ]) régulée mémétiquement par les médias sociaux. À cet apport Twitter s’ajoutent mon épluchage des quotidiens et mon agrégation de flux RSS. L’information passe donc par plusieurs cribles, dans un crescendo d’objectivation. Fondamentalement, je n’agis plus seul. Par ricochet :
Emotion reversed in left-handers brains The way we use our hands may determine how emotions are organized in our brains, according to a recent study published in PLoS ONE by psychologists Geoffrey Brookshire and Daniel Casasanto of The New School for Social Research in New York. Motivation, the drive to approach or withdraw from physical and social stimuli, is a basic building block of human emotion. For decades, scientists have believed that approach motivation is computed mainly in the left hemisphere of the brain, and withdraw motivation in the right hemisphere. Brookshire and Casasanto's study challenges this idea, showing that a well-established pattern of brain activity, found across dozens of studies in right-handers, completely reverses in left-handers. The study used electroencepahlography (EEG) to compare activity in participants' right and left hemispheres during rest. A New Link Between Motor Action and Emotion Most cognitive functions do not reverse with handedness.
