It was not […]

Many of today’s electronic devices — from the semiconductors in your cell phone to the photovoltaic cells in your solar panels — are built on thin-film substrates. The thin film is an electronically conductive material while the substrate is an inert material. Or is it? Physicists and materials scientists have long assumed substrates do not […]
Author: Marta Sánchez López, Postdoctoral researcher at Research Centre for Basque Language and Texts (CNRS-IKER) – Université Bordeaux Montaigne. She also collaborates with the The Bilingual Mind Research Group (Gogo Elebiduna), University of the Basque Country. In our daily life, we perceive many different events around us with different participants involved, such as a woman […]
Author: Subir Sarkar, Emeritus Professor, Department of Physics, University of Oxford According to our best understanding, the universe is expanding – and is doing so at an accelerating rate. This is believed to be caused by something called the “cosmological constant”, which was first proposed by Albert Einstein in his theory of general relativity. In […]
Researchers at the University of Michigan have created a device that enables them to control the flow of electrons through a semiconductor using only laser light—no electrical power source required. This device was built to explore fundamental physics and realize a previously unobserved behavior, but it could also open doors for new applications in areas […]
For decades, Alzheimer’s research has been dominated by a seemingly intuitive idea: the disease is largely explained by the accumulation of abnormal proteins in the brain, primarily beta-amyloid and tau. However, while this view has been useful, it has fallen short in explaining certain fundamental aspects. One of the most striking is that Alzheimer’s affects […]
Building electronic devices often requires stacking different crystalline materials on top of one another with atomic precision. This process, called heteroepitaxy, works best when the two crystals share similar atomic patterns. When their symmetries differ, the upper crystal tends to grow in several orientations at once instead of a single one, creating defects that degrade […]
Auhtors: Samantha Lawler, Associate Professor, Astronomy, University of Regina and Aaron Boley, Professor, Physics and Astronomy, University of British Columbia A giant mirror to create “sunlight on demand” was just approved by the United States Federal Communications Commission (FCC), despite opposition from astronomers and the public, and real safety concerns. The FCC approved the company […]

Sugars are key biomolecules in living organisms, as they form the backbone of DNA and RNA and play a fundamental role in metabolic processes. In theories of the origin of life, sugars are also essential for the synthesis of the first nucleic acids. Despite their importance, one of the major questions in origin-of-life research is […]
What if we could stop blood cancers before they even start? New research reveals that chronic inflammation dramatically reshapes the bone marrow environment years before leukemia emerges, potentially offering a window for early intervention. The Hidden Life of the Bone Marrow Every second, your bone marrow produces millions of new blood and immune cells through […]
