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. BBC Personalized […]
Uropathogenic Escherichia coli (UPEC) is responsible for approximately 90% of urinary tract infections (UTI) seen in individuals with an ordinary anatomy. In ascending infections, fecal bacteria colonize the urethra and spread up the urinary tract to the bladder as well as to the kidneys (causing pyelonephritis), o or the prostate in males. Because women have […]
The progress that physics experienced during the 20 th century was probably one of the greatest and most everlasting successes of the humankind. Discovering the hidden and minute composition of matter and energy, as well as realising that the rules they obey are as further from common sense as quantum theory has revealed, are amongst […]
Author: Nicola Molinaro is an Ikerbasque Research Fellow at BCBL – Basque Center on Cognition, Brain and Language Research on language comprehension has always underscored the speed and precision with which the brain integrates and process the input while at the same performing multiple parallel tasks. This extreme efficiency is explained by the ability of […]
