The revolutionary theory of topological quantum chemistry , a description of the universal global properties of all possible band structures and materials, diagnoses topological phases based on elementary band representations. A set of bands is topological if it lacks an “atomic limit” that obeys the crystal symmetry (and time reversal, if desired): formally, an atomic […]

Author: Francisco J. Blanco is an Ikerbasque Research Professor at CIC bioGUNE Molecular interactions in cell membranes, particularly lipid-protein interactions in their hydrophobic core, are difficult to analyse and remain poorly characterised despite high relevance in physiological and pathological processes. Structural rearrangements in membranes and embedded proteins, and the way molecular interactions contribute to their […]

In this article I summarize the recently published paper by José Alcalde . In this article, the author discusses the current matching mechanism that is used in Spain to assign medical graduates who pass the MIR exam to residency positions. The system works as follows. Students are ranked according to their marks in the MIR […]

New map offers detailed view of Antarctica A new high-resolution map is giving researchers a much more detailed view of Antarctica. Images from the Reference Elevation Model of Antarctica, or REMA, will be made available for free to scientists studying the continent. The New York Times Ancient lava tubes may be behind unusual swirls on […]

Chemists have a range of different spectroscopic techniques to study organic molecules. All of these techniques are based on spectra generated by a range of electronic transitions and vibrations, key excitations in matter, the study of which provides information about characteristics of materials and, therefore, allow their identification. In this context, one of those spectroscopic […]

“ It is often said that all the conditions for the first production of a living organism are now present, which could ever have been present.— But if (& oh what a big if) we could conceive in some warm little pond with all sorts of ammonia & phosphoric salts, light, heat, electricity etc present […]

Turning simple, individual molecules into complex, interconnected materials is the core of polymer chemistry. There is currently an increasing demand for materials with sophisticated properties such as self-healing and reusable adhesivity. However, achieving polymers with such functionalities generally demands higher structural complexity, synthetic difficulty, and cost. Now, a team of chemists has designed a supramolecular […]

Deep Earth scar keeps Mount St. Helens out of line with other volcanoes The Mount St. Helens volcano in Washington state doesn’t line up with other volcanoes in the Cascades mountain range because old tectonic collisions created a scar in Earth’s crust beneath it, changing how the magma flows. Live Science Juno data reveal Jupiter’s […]

The properties of bismuth have long defied classification, placing it in a category of its own. Now, as if it was not enough, it turns out its electronic structure has higher-order topology. This has been shown by an international team with the participation of Maia G. Vergniory (DIPC, Ikerbasque, UPV/EHU) and coordinated by Titus Neupert […]

If there is one worrisome fact about science here and now, it is this: the possibility that a huge amount of publications is to be retracted due to falsified or duplicated data. The phenomenon is not new, there have been more than a few reports sounding the alarm on precisely this problem, and there is […]
