Researchers at the University of Oregon have developed an artificial intelligence tool that can read genetic code the way large language models like ChatGPT read text. Scanning the genome for biological mutation patterns, the computer model traces pairs of genes back in time to their last common ancestor. It’s the first language model designed for […]

In recent years, “twistronics” has shown that simply changing how two crystal layers sit on top of each other can completely transform their electronic behavior. When two lattices are slightly mismatched in size or rotated by a small angle, they create a larger repeating interference pattern called a moiré superlattice. This long-wavelength pattern acts like […]

DELTA is a 1.5-GeV synchrotron radiation source operated by the TU Dortmund University. This singular university-based facility with emphasis on research and education, offers high degree of flexibility both for user experiments and accelerator physics and technology. Most of the world’s synchrotrons are designed to provide a continuous supply of radiation to users in a […]

Earth’s atmosphere is a vast, swirling engine of weather and climate. Jet streams race across continents, storms spin into hurricanes, and invisible eddies churn the air at every scale. For decades, scientists have struggled to understand exactly how energy and swirling motion flow through these turbulent systems, especially in the layered zones where the air […]

New research numerically demonstrates how carefully structured materials can control light in ways that are both precise and robust. It brings together ideas from photonics and topology to show how a laser can emerge from the boundary between two distinct optical regimes. The physical system considered in the study is a bilayer photonic crystal. A […]

Korean researchers have confirmed that underground wireless communication is possible, moving beyond the terrestrial wireless communication they have primarily focused on until now. This opened up a new wireless channel for confirming the survival of buried people in the event of a collapse of an underground facility such as a mine, conducting underground rescue operations […]

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 […]

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 […]

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 […]
