A quiet revolution is unfolding in the study of distant galaxies, one that lets astronomers pinpoint individual stars across the vast gulfs of time and space. Using the James Webb Space Telescope (JWST), a team of researchers has identified 1 over 40 individual stars in a single galaxy located halfway across the observable universe. These stars weren’t visible through any ordinary means—they were seen because the universe itself magnified them for us.

Quantum simulation, a concept that once seemed like science fiction, is now revolutionizing the way physicists study the quantum world. The idea, famously suggested by Richard Feynman in the 1980s, is to use a controllable quantum system to mimic the behaviour of another system that is too complex to study directly. Over time, researchers have developed various platforms—ranging from ultracold atoms to photonic lattices and engineered electronic materials—that make this idea a reality.

The interplay between the electron and phonon dynamics in 2D materials is a complex and fascinating subject. By examining the behaviour of NbSe₂ on graphene, a new study has provided new insights into how substrates influence superconductivity through moiré phonons. In recent years, the study of two-dimensional (2D) materials has transformed the field of condensed matter physics.

X-ray fluorescence imaging (XFI) is a powerful technique that enables scientists to visualize and map the distribution of elements within various samples, including biological tissues. By detecting the unique fluorescent signals emitted by elements when they are excited by X-rays, XFI provides detailed information about the elemental composition and spatial distribution in a non-destructive manner.

Estados Unidos consigue aterrizar suavemente en la Luna por primera vez en el siglo XXI. Y no, no ha sido ninguna empresa del Reichsführer-DOGE (aunque usase un Falcon 9 de Space X para el lanzamiento). Desde el Apolo 17 en 1972 EE. UU. no lograba posar una nave en la superficie lunar sin ningún problema. El módulo lunar Blue Ghost M1 aluniza con éxito, por Daniel Marín.
