Every time a computer processes information, electrons shuttle through circuits carrying electric charge, and much of the energy they carry is wasted as heat. Spintronics proposes a different approach: instead of relying solely on the charge of electrons, exploit another of their properties called spin, a quantum-mechanical quantity that can be thought of as a […]

Author: Ry Holland, Research Fellow in Microbial Ecology, Monash University Winter in Antarctica is long and dark. Temperatures remain well below freezing. In many places, the Sun sets in April and does not rise above the horizon again until August. Without sunlight, photosynthetic life such as plants, mosses and algae cannot make energy. But that’s […]

MIT neuroscientists have figured out how the brain is able to focus on a single voice among a cacophony of many voices, shedding light on a longstanding neuroscientific phenomenon known as the “cocktail party problem.” This attentional focus becomes necessary when you’re in any crowded environment, such as a cocktail party, with many conversations going […]

T-cell lymphoblastic lymphoma (T-LBL) is a precursor T cell lymphoma. T-LBL represents the second most common subtype of Non-Hodgkin lymphoma in both children and adolescents; however, it is less common in adults . T-LBL share many characteristics with the precursor T cell leukemia (T-ALL), however, various studies have indicated that T-ALL and T-LBL might be […]

Imagine taking two identical sheets of chicken wire and laying them on top of one another. If you align them perfectly, they look like a single sheet. But if you rotate the top layer by just a tiny amount, a beautiful large-scale crawling pattern emerges. In physics, we call this a Moiré pattern. When we […]

Author: Atheena Johnson, Docteure en linguistique appliquée, Université Paris Nanterre Over the decades, technological devices have been gradually integrated into language learning, as is recently the case with generative artificial intelligence (AI). Does the sophistication of these tools eventually render pencils and pens obsolete? Or can digital uses be combined with handwriting? How does writing […]

University of Houston professor of psychology Arturo Hernandez is disputing a high-profile study claiming that people who live in multilingual countries show healthier brain aging. Though the study got lots of attention, Hernandez and collaborators report that the findings warrant cautious interpretation and reframing of public health implications. “We took a closer look and argued […]

During the last decade, neurodegenerative diseases have often been described as fires spreading silently from one neuron to another. We knew that misfolded proteins such as alpha‑synuclein could travel across neural circuits, igniting new pathological hotspots along the way. What we did not know is that, behind the scenes, astrocytes —those tireless caretakers of the […]

The classic chemical garden experiment is a staple of introductory chemistry, where colorful, plant-like structures sprout from metal salt crystals dropped into a solution of sodium silicate. While these vibrant tubes look like biological life, they are entirely inorganic, driven by the physics of osmosis and the chemistry of precipitation. For decades, scientists have admired […]

Author: Jordi Diaz Marcos, CCiTUB , Universitat de Barcelona As good citizens, we diligently fill the recycling bins provided by our local authorities with all manner of plastic trays, boxes, bottles and bags. But as these bins fill up quicker and quicker each week, an awkward question arises: is all this effort actually doing any […]
