¿Cómo defiende nuestro cuerpo su integridad frente a los millones de microbios que lo acechan cada día? Hoy en día, la respuesta parece obvia: gracias al sistema inmunitario. Sin embargo, a finales del siglo XIX, la ciencia estaba convencida de que la sangre era simplemente un fluido de transporte y que las infecciones se combatían de forma puramente química. Todo cambió gracias a un hombre de temperamento volcánico, una mente brillantemente intuitiva y una espina de rosal: Ilya Metchnikov.
Considerado el padre de la inmunología celular y galardonado con el Premio Nobel de Fisiología o Medicina en 1908, Metchnikov no solo transformó nuestra comprensión de las enfermedades, sino que también sentó las bases de la revolución moderna de los probióticos y el estudio del envejecimiento.

La diversidad lingüística que ha llegado hasta hoy es la superviviente de un tamiz histórico masivo y fuertemente selectivo
Data collected by NASA's missions about interstellar comet 3I/ATLAS will continue to reveal insights about the comet and interstellar objects at large.
Un análisis liderado por la Universidad de Oxford revela que la expansión masiva del pollo de granja ha creado las condiciones idóneas para que Campylobacter, una bacteria antes recluida en aves silvestres, prolifere, adquiera resistencia a los antibióticos y amenace la salud pública global.
Uranus doesn't just experience extreme seasons—its lopsided orbit traps each pole in decades of uninterrupted darkness or light, creating weather patterns unlike anything else in the solar system.
In the latest research, telescope observations of 3I/ATLAS examine its chemical structure and suggest that it took shape in a peripheral region of a relatively calm planetary system
DESI’s largest 3D map of the universe could reveal how dark energy shapes cosmic evolution through the most detailed universe map ever created.
A uranium fuel pellet the size of a fingertip holds roughly the energy of a tonne of coal — and a typical reactor core stacks about ten million of them into twelve-foot zirconium rods. Here's how the math, the metallurgy, and the physics actually work.
The latest nuclear-powered submarine cruiser Ulyanovsk, has been rolled out of the construction hall at the Sevmash shipyard United Shipbuilding Corporation in Severodvinsk. The ceremony was overseen by Commander-in-Chief of the Russian Navy...
Researchers tracked genetic changes in a bacteria that causes food-poisoning in bird populations, and found large-scale poultry farming is linked to antimicrobial resistance.
Researchers fed a Komodo dragon a goat to figure out if Homo floresiensis truly were the hunters they were originally thought to be.
The Via Egnatia was an ancient Roman road that ran from the Adriatic Sea to Byzantium, connecting northern ancient Greek cities.
One of the greatest minds of philosophy, Socrates' views on death made him go down in history for his taking of poison after his trial.
Socrates’ reflections on death, especially his belief that it is either a peaceful sleep or a transition to another existence, offer a powerful perspective on facing mortality. As we navigate a world filled with uncertainty, his teachings provide timeless wisdom that can help alleviate the fear of death, encouraging us to live with greater purpose and serenity.
