Así funcionan los eclipses solares: ¿por qué, cómo, cuándo, dónde? En 1959 pudo verse el último eclipse total de sol hasta hoy en España, solo en las islas Canarias. En la Península, el último total acaeció hace más de un siglo, en 1912. Esta escasez histórica se rompe ahora con una racha excepcional, dos totales y otro anular en solo tres años. ¿Cómo se explican estos fenómenos?

🌘 Tras más de un siglo sin un eclipse total visible desde la Península, España encadena una racha extraordinaria: tres espectáculos solares en solo tres años, entre totales y anular. Una coincidencia astronómica tan rara como fascinante.

Watch: Trump announces 'major combat operations' in Iran US President Donald Trump accuses the Iranian regime of waging an "unending campaign of bloodshed and mass murder targeting the United States".

A guy (president of a country) with a baseball cap ( 😱 Oh, the hick! ) that kills anothe leader of another country (without trial or judge) (were he guilty) is not a respectable or convenable guy.

Inside the cutthroat competition for the best baguette in Paris The Grand Prix de la Baguette de Tradition Française, Paris’s most revered bread competition, saw dozens of bakers competing for the title of best baguette.

Non, non et non ! Il y a du pain a Paris meilleur que cette baguette ! Au levain, plus compact, moins de croûte "croustillante" et fait avec de "vrai" farine complète. Mais les gens ont perdu leur boussole.

Platt added: the findings indicate that intimate relationships for modern human ancestors weren’t solely dependent on Survival of the Fittest ( so to speak) but “can also stem from cultural and social interactions.”

♀♀ H. s. s. X ♂♂ H. neanderthal >> ♀♀H. n. x ♂♂ H. s.
But I don't agree with them saying: "The most likely explanation for this sex bias is Mate Preference".
Why not incompatibility, sterility or other genetic factors ? About F1.

France 2030 : le CNRS lance un nouveau programme de recherche en robotique Un nouveau programme ambitieux de recherche « Robotique » est lancé ce 3 février. Dans le cadre de France 2030 et de sa stratégie « Robotique et machines intelligentes », le CNRS pilote et fédère la recherche « amont » qui vise à développer des solutions matérielles et logicielles innovantes afin d’améliorer les performances et la sobriété des systèmes robotiques. Elaboré avec des partenaires de recherche et industriels, ce programme vise à favoriser des avancées issues de la recherche fondamentale en robotique vers des applications concrètes dans divers domaines, de l’industrie aux services. Ce programme, opéré par l’ANR, est doté d’un budget de 30 millions d’euros de France 2030 sur 6 ans et demi.

- La Nature a expérimente durant des millions d'années.
- Les solutions ont déjà été trouves par elle.
- Quand vont'ils mettre un biologiste (a spectre large) dans le staff ?

"Unnatural alliance" ? (The liberal tolerates religion, the libertine prefers his bed). He cynically exploited it to gain power by using white evangelical circles for his own ends. He likely bought at least part of their support through a "quid pro quo" arrangement.

AI is threatening science jobs. Which ones are most at risk? Data-analysis and modelling positions are already becoming obsolete, but hands-on experimentalists can breathe easy for now.

AI never could be "Imaginative". They could call it "Generative" (as the reproductive parenthood in the nature where DNA copies existent DNA). But, without Natural Selection ( discarding "hallucinations") never could become human intelligence: HI !
