![]() | The RNA revolution: How our understanding of life's blueprint is being rewrittenFor decades, the central dogma of molecular biology—DNA makes RNA, RNA makes protein, protein makes phenotype—was the guiding framework for understanding inheritance and disease. This model explained classic Mendelian traits, such as how single DNA mutations in protein-coding regions could cause diseases like sickle cell anemia. Yet, this accounts for only about 2% of Mendelian inheritance and the resulting phenotypic changes. |

The robot operated for the first time on a lifelike patient, and during the operation, responded to and learned from voice commands from the team—like a novice surgeon working with a mentor. |

Cher Olivier Hartmanshenn,
Voici votre newsletter Science X personnalisée de la semaine 28 :
Une étude révèle que les figuiers convertissent le CO₂ atmosphérique en pierre
De nouvelles recherches révèlent que certaines espèces de figuiers stockent du carbonate de calcium dans leur tronc, se transformant ainsi (partiellement) en pierre. Une équipe de scientifiques kenyans, américains, autrichiens et suisses a découvert que ces arbres pouvaient extraire le dioxyde de carbone (CO₂) de l'atmosphère et le stocker sous forme de « roches » de carbonate de calcium dans le sol environnant.
Une nouvelle étude montre que les tortues éprouvent des sentiments similaires aux nôtres.
Des experts en comportement animal et en cognition de l'Université de Lincoln, au Royaume-Uni, ont fait de nouvelles découvertes sur la sensibilité des reptiles, qui pourraient transformer la façon dont ils sont élevés en captivité.
Des scientifiques reconstituent en détail l'évolution du niveau de la mer sur 540 millions d'années
Le niveau de la mer sur Terre monte et descend depuis que l'eau existe. Les scientifiques pouvaient déjà utiliser des sédiments et des fossiles pour reconstituer grossièrement l'évolution du niveau de la mer sur des intervalles d'un million d'années ou plus.
Manger tard est associé à un métabolisme du glucose altéré
Nos processus métaboliques diffèrent selon l'heure de la journée, et beaucoup d'entre eux sont plus actifs le matin que le soir. Bien que des études montrent que manger tard le soir est associé à un risque accru d'obésité et de maladies cardiovasculaires, on sait peu de choses sur l'impact de l'heure à laquelle nous mangeons sur le métabolisme du glucose et dans quelle mesure ce phénomène est génétiquement déterminé.
Une protéine cérébrale clé pourrait détenir des réponses aux pertes de mémoire et aux maladies neurodégénératives
Des scientifiques ont découvert comment une protéine clé contribue au maintien de connexions solides entre les cellules cérébrales, essentielles à l'apprentissage et à la mémoire.
Le chat d'un scientifique contribue à nouveau à la découverte d'un nouveau virus
Pepper, le chat domestique qui a fait la une des journaux l'année dernière pour son rôle dans la découverte du premier virus jeilong aux États-Unis, remet le couvert. Cette fois, ses prouesses de chasseur ont contribué à l'identification d'une nouvelle souche d'orthoréovirus.
La datation au radiocarbone révèle que Rapa Nui n'est pas aussi isolée qu'on le pensait.
Des archéologues ont analysé des espaces rituels et des structures monumentales à travers la Polynésie, remettant en question l'idée selon laquelle Rapa Nui (île de Pâques) se serait développée de manière isolée après sa colonisation initiale.
Un bracelet-capteur offre une surveillance complète du diabète et des soins cardiovasculaires.
Un nouveau bracelet-capteur portable pourrait améliorer considérablement la gestion du diabète en suivant en continu non seulement la glycémie, mais aussi d'autres signaux chimiques et cardiovasculaires qui influencent la progression de la maladie et la santé globale. Cette technologie a été publiée dans Nature Biomedical Engineering.
La Terre est-elle à l'intérieur d'un immense vide ? Le « bruit du Big Bang » suggère une solution possible à la tension de Hubble.
La Terre et l'ensemble de notre galaxie, la Voie lactée, pourraient se trouver à l'intérieur d'un mystérieux trou géant qui entraînerait une expansion plus rapide du cosmos à cet endroit que dans les régions voisines de l'univers, selon les astronomes.
Un nouveau composé organométallique remet en question un principe fondamental de la chimie classique
Depuis plus d'un siècle, la célèbre règle des 18 électrons guide le domaine de la chimie organométallique. Des chercheurs de l'Institut des sciences et technologies d'Okinawa (OIST), en collaboration avec des scientifiques allemands, russes et japonais, ont synthétisé avec succès un nouveau composé organométallique qui remet en question ce principe établi de longue date. Ils ont créé un dérivé stable à 20 électrons du ferrocène, un complexe organométallique à base de fer, qui pourrait ouvrir des perspectives prometteuses en chimie.
Des scientifiques créent un système d'intelligence artificielle biologique
Des scientifiques australiens ont développé avec succès un système de recherche utilisant l'intelligence artificielle biologique pour concevoir et faire évoluer des molécules aux fonctions nouvelles ou améliorées directement dans les cellules de mammifères. Les chercheurs affirment que ce système offre un nouvel outil puissant qui aidera les scientifiques à développer des outils de recherche ou des thérapies géniques plus spécifiques et plus efficaces.
D'énormes rochers éjectés lors de la mission DART pourraient compliquer les futurs efforts de déviation d'astéroïdes
Lorsque la sonde DART de la NASA a percuté la lune astéroïde Dimorphos en septembre 2022, elle n'a pas seulement modifié l'orbite de l'astéroïde comme prévu : elle a également libéré une énorme pluie de rochers dont la vitesse était plus de trois fois supérieure à celle de la sonde elle-même.
L'ADN néandertalien pourrait être à l'origine de certaines malformations cérébrales modernes
Si vous souffrez régulièrement de maux de tête, de vertiges, de troubles de l'équilibre et d'une vision floue, nos cousins néandertaliens pourraient en être responsables.
L'art rupestre évoque les origines des rois égyptiens
Un panneau d'art rupestre près d'Assouan, en Égypte, pourrait représenter un exemple rare d'un individu d'élite de la Première Dynastie, éclairant ainsi la formation de l'État égyptien antique.
