Organic molecules of unprecedented size discovered on Mars
These long carbon chains, containing up to 12 consecutive carbon atoms, could exhibit features similar to the fatty acids produced on Earth by biological activity.

(24 Mar) Scientists Find Giant Organic Molecules on Mars as Old as Life on Earth
The longest organic molecules yet found on Mars are very similar to those produced by life on Earth.

[Le #JWST, booster de connaissances !] Depuis sa mise en service en juillet 2022, le James Webb Space Telescope a dévoilé un nombre inattendu de #galaxies anciennes et de #TrousNoirs supermassifs dans l' #univers jeune, l'abondance de #molécules carbonées au sein des #DisquesProtoplanétaires, la composition chimique de l' #atmosphère d' #exoplanètes proches de la Terre, etc.
Le journal du @cnrs revient sur l'ensemble de ces découvertes avec quelques-uns des scientifiques impliqués - notamment Olivier Berné, astronome à l'IRAP.

As #scientific advancements unveil the mysteries of the universe, it becomes increasingly evident that everything appears to operate mechanistically. #Atoms, #molecules, #stars, #planets, #cells, and #biological systems are fundamentally mechanical. If the existence of a #supernatural, invisible soul within my body is negated, then it is undeniable that I too am a machine.

After atoms, it's now the turn of molecules to form a Bose–Einstein condensate.
"Physicists have succeeded in cooling down molecules so much that hundreds of them lock in step, making a single gigantic quantum state. These systems could be used to explore exotic physics, such as by creating solid materials that can flow without resistance, or could form the basis of a new kind of quantum computer."

"In Phase I we find #AI-discovered #molecules have an 80–90% success rate, substantially higher than historic industry averages. This suggests, we argue, that AI is highly capable of designing or identifying molecules with drug-like properties. In Phase II the success rate is ∼40%, albeit on a limited sample size, comparable to historic industry averages."
