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 […]
The reward pathway is a group of brain structures connected to each other that are key in the processes of motivation (desire, motivation, craving), associative learning (operant reinforcement and positive conditioning) and in positive emotions, particularly those in which pleasure has a fundamental component such as joy, euphoria and ecstasy. The reward is an attractive […]
A new shape inside your skin The type of cells responsible for forming skin and the lining of an organism’s organs will morph into “scutoids” in order to accommodate those organs’ complex curvature. Motherboard A leap toward lifelike model of human heart Scientists have bioengineered a 3D model of the human heart’s left ventricle, which […]

Most of the theories describing dynamical processes at surfaces rely on the validity of the adiabatic Born-Oppenheimer approximation. What does this mean? We have already seen that adsorption commonly is understood as the reversible binding of molecules and atoms from the gaseous or liquid phase on surfaces, mostly of highly porous adsorbent media. In chemisorption […]
Metallic glasses are a unique class of materials whose properties combine some of the irreconcilable properties of both metals and polymers. They consist of a combination of metals which, in the solid state, present an amorphous atomic structure, in contrast to common metal alloys, which present a highly ordered microscopic pattern. This lack of crystalline […]
Author: Roberto D’Agosta is an Ikerbasque Research Professor at ETSF and the Department of Materials Physics in the Faculty of Chemistry at the UPV/EHU in San Sebastian. Francesca Baletto, senior lecturer at King’s College London, read and commented the manuscript. Every single moment, nature exploits catalysis to make or improve specific chemical reactions. Catalysts facilitate […]
Gulf Stream’s slowdown may increase global temperatures The slowing of the Gulf Stream could lead to higher temperatures around the world. Researchers examined the Atlantic Meridional Overturning Circulation over the past seven decades and noted patterns that suggest Earth could be experiencing a similar warming period as it did from 1975 to 1998.
