In the realm of modern physics, few materials have captured the imagination quite like graphene, a single layer of carbon atoms arranged in a honeycomb lattice. Its remarkable properties, such as exceptional electrical conductivity and strength, have made it a cornerstone of research into quantum materials. A recent study published in Nature 1 takes this fascination a step further by exploring how electrons interact with vibrations in a special configuration called twisted bilayer graphene (TBG).

Nanotechnology is like a playground for scientists, where they tinker with materials at the scale of atoms to create new tools and devices with extraordinary properties. One of the most exciting areas in this field involves nanographenes, which are tiny pieces of graphene—a single layer of carbon atoms arranged in a honeycomb pattern, known for its strength and ability to conduct electricity.

Imagine peering through a microscope, marvelling at the intricate dance of cells, proteins, or tiny structures within a living organism. These images, known as bioimages, are a treasure trove of information for scientists studying life’s mysteries, from how cells divide to how diseases disrupt tissues. But analysing these images is no small feat. The sheer volume of data and the complexity of patterns often require advanced computational tools.

Imagine sending a tiny particle, like an electron, through a material so thin it’s just a single layer of atoms. You’d expect it to take a certain amount of time to pass through, right? Maybe a little longer if the material gets thicker, or shorter if it’s super thin. But what if the electron seemed to zip through faster than it should, or even appeared to arrive before it was supposed to?

Imagine a glass of water or a bottle of ethanol. These are molecular liquids, substances where molecules are free to move but are still closely packed, interacting with each other through forces like hydrogen bonds or weaker attractions. Scientists have long been fascinated by how these molecules move and interact, especially at scales that are neither as small as individual atoms nor as large as the bulk liquid we see with our eyes.

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.
