A team of researchers has experimentally demonstrated a quantum tornado for the first time by refining an established method. In the quantum semimetal tantalum arsenide (TaAs), electrons in momentum space behave like a swirling vortex. This quantum phenomenon was first predicted eight years ago. Scientists have long known that electrons can form vortices in quantum […]
In the vast expanse of the universe, galaxies are not isolated islands but are interconnected through a vast network known as the “cosmic web.” This intricate structure, composed of dark matter and gas, forms the backbone of the cosmos, guiding the formation and evolution of galaxies. Recent advancements have allowed astronomers to capture a high-definition […]
Author: Frédéric Bernard, associate professor in neuropsychology, Université de Strasbourg We’ve all experienced it: you’re in the middle of a conversation, searching for a word, a name, or a title, and… nothing. You know you know it–you can almost feel it–but it just won’t come. This phenomenon, known as having a word “on the tip […]
You have probably heard the saying that the eyes are the windows to the soul, but now it turns out that they are also connected to how we breathe. Scientists have long studied the size of our pupils to understand attention, emotion and even medical conditions. But now, new research has surprisingly revealed that they […]
In a leap forward for quantum computing, a Microsoft team led by UC Santa Barbara physicists on Wednesday unveiled an eight-qubit topological quantum processor, the first of its kind. The chip, built as a proof-of-concept for the scientists’ design, opens the door to the development of the long-awaited topological quantum computer. “We’ve got a bunch […]
Author: José R. Pineda got his Ph.D. from University of Barcelona in 2006. Since 2007 he has worked for Institut Curie and The French Alternative Energies and Atomic Energy Commission. Currently he is a researcher of the UPV/EHU. He investigates the role of stem cells in physiologic and pathologic conditions. Schizophrenia is a chronic and […]
Hydrogels are fascinating materials that can absorb and retain large amounts of water, making them useful in various fields such as medicine, environmental science, and engineering. A recent study has explored a new type of hydrogels made from cellulose nanofibres (CNFs) and lignocellulose nanofibres (LCNFs), aiming to enhance their strength and water-absorbing capabilities. Cellulose and […]
The ability to uptake cellular debris and process the engulfed antigens for MHC class I presentation is mainly performed by a minority subset of dendritic cells . Immunologists identified them as “conventional-type 1 dendritic cells”, and characterized them identifying the presence of surface coexpression of CD11c, XCR1, and DNGR-1 molecules . In mice, two subsets […]
For decades, Type Ia supernovae have played a pivotal role in the discovery and study of dark energy—the mysterious force responsible for the accelerating expansion of the Universe. To do so, cosmologists compare two quantities: the redshift, i.e., the photon’s wavelength stretch caused by the geometrical expansion of the Universe ; and the Supernovae brightness […]
Cement is a fundamental material in modern construction, used in everything from buildings to bridges. One of its key components, tricalcium aluminate (C₃A), plays a crucial role in determining cement’s setting time and durability. A recent study has provided new insights into how C₃A behaves under heat, combining computer simulations with experimental data to deepen […]
