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. But when scientist Eric Lander looks at this he sees stories. ERIC LANDER (Whitehead Institute/MIT): The genome is a storybook that's been edited for a couple billion years. And you could take it to bed like A Thousand and One Arabian Nights, and read a different story in the genome every night. 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. 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... ROBERT KRULWICH: I eat a banana. We asked Dr.
Genetic Disease Causes, Types, and Conditions Information on MedicineNet What is a genetic disease? A genetic disease is any disease that is caused by an abnormality in an individual's genome. The abnormality can range from minuscule to major -- from a discrete mutation in a single base in the DNA of a single gene to a gross chromosome abnormality involving the addition or subtraction of an entire chromosome or set of chromosomes. Some genetic disorders are inherited from the parents, while other genetic diseases are caused by acquired changes or mutations in a preexisting gene or group of genes. Mutations occur either randomly or due to some environmental exposure. What are the different types of inheritance? There are a number of different types of genetic inheritance, including the following four modes: Medically Reviewed by a Doctor on 1/15/2014 Patient Comments Viewers share their comments Genetic Disease - Symptoms Question: What were the symptoms of a genetic disease in you or a relative?

Genes to Cognition Online 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. 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. "We predicted this hemispheric reversal because we observed that people tend to use different hands to perform approach- and avoidance-related actions," says Casasanto.

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. 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. La mémoire y gagne à la fois en répétition, à la fois par maillage de sens.
