genome transplantation

Les gènes ne jouent qu’un rôle mineur, disait l’autre

Science Daily — Researchers at the J. Craig Venter Institute (JCVI) have announced the results of work on genome transplantation methods allowing them to transform one type of bacteria into another type dictated by the transplanted chromosome. The work, published online in the journal Science, by JCVI’s [...]

Evolution of cooperation in a finite homogeneous graph

Ca par exemple ! Mignon tout plein. M’est avis que c’est de la bonne

Vol 447 | 24 May 2007 | doi:10.1038/nature05784

Recent theoretical studies of selection in finite structured populations have worked with one of two measures of selective advantage of an allele: fixation probability and inclusive fitness. Each approach [...]

Ignorance is no crime

Scientific American, July 2007
p 890 :

Dawkins: [...] Ignorance is no crime. To call somebody ignorant is no insult. All of us are ignorant of most of what there is to know. I am completely ignorant of baseball, and I dare say that you are as completely ignorant of cricket. If I tell somebody who believes [...]

Since its humble beginnings as a single cell, life has evolved into a spectacular array of shapes and sizes, from tiny fleas to towering Tyrannosaurus rex, from slow-soaring vultures to fast-swimming [...]

pair-rule

Le dernier post de PZ Myers (23/06/2007) tombe à pic après la lecture de Setting the Tempo in Development.
Merde, si les gradients de morphogènes sont présents dans l’oeuf déjà et qu’ils sont les produits d’expression de gènes il se peut que Fleury ait tort ! Est-ce possible ? Probablement oui.

Darwinian evolution is a marvelous thing

This is rather like indicting the germ theory of disease for not predicting the motions of the planets. Darwinian evolution is a marvelous thing, but it by its nature it has little to say about the minutiae of embryological development or the structure of the genome
Tiens, je ne suis pas le seul à le penser [...]
