We report the design, synthesis, and assembly of the 1.08-Mbp Mycoplasma mycoides JCVI-syn1.0 genome starting from digitized genome sequence information and its transplantation into a Mycoplasma capricolum recipient cell to create new Mycoplasma mycoides cells that are controlled only by the synthetic chromosome. The only DNA in the cells is the designed synthetic DNA sequence, including “watermark” sequences and other designed gene deletions and polymorphisms, and mutations acquired during the building process. The new cells have expected phenotypic properties and are capable of continuous self-replication.

Le médecin, le malade et sa maladie

Par Vincent Pointillart,    chirurgien au CHU de Bordeaux

Ce titre emprunté à Balint évoque combien la qualité de la relation médecin malade influe sur le résultat d’une prise en charge qui ne doit pas en être moins technique. Il veut aussi souligner que cette relation n’est pas sans retentissement sur le médecin lui-même, s’il accepte d’être confronté à d’autres réalités plus humanistes.

New evidence for quantum Darwinism found in quantum dots

(PhysOrg.com) — Physicists have found new evidence that supports the theory of quantum Darwinism, the idea that the transition from the quantum to the classical world occurs due to a quantum form of natural selection. By explaining how the classical world emerges from the quantum world, quantum Darwinism could shed light on one of the most challenging questions in physics of the past century.

Tiens, je ne connaissais pas le darwinisme quantique, il y en a qui doivent se sentir poursuivis jusqu’à chez eux

J’aime beaucoup la façon de se positionner d’un des auteurs, David Ferry, interviewé par PhysOrg.com :

“It is a theory, and our data provides support,” he said. “But, the experiments have to be confirmed by other groups, perhaps many times if the theory is to be fully accepted.”
