Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the researchers, who include those at the University of California, Irvine.
Quantum low-density parity-check codes are highly efficient in principle but challenging to implement in practice. This proposal shows that these codes could be implemented in the near term using recently demonstrated neutral-atom arrays.
In this Tools of the Trade article, Samuel Gould explains how prime editing sensors can improve experimental efficiency and can be designed using a computational tool he created and named PEGG.

Learn how Quantum Bayesianism challenges traditional quantum mechanics by focusing on the role of the observer in creating quantum reality.
Researchers using the JWST may have found evidence of the Universe’s first stars. Called Population III stars, they were massive and hot.
A team at HZB has investigated a new, simple method at BESSY II that can be used to create stable radial magnetic vortices in magnetic thin films.
In some materials, spins form complex magnetic structures within the nanometre and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such structures are magnetic bubbles, skyrmions, and magnetic vortices.
Spintronics aims to make use of such tiny magnetic structures to store data or perform logic operations with very low power consumption, compared to today’s dominant microelectronic components. However, the generation and stabilization of most of these magnetic textures is restricted to a few materials and achievable under very specific conditions (temperature, magnetic field…).

Nuclear energy has long been regarded as a next-generation energy source, and major countries around the world are competing to secure cutting-edge technologies by leveraging the high economic efficiency and sustainability of nuclear power. However, uranium, which is essential for nuclear power generation, has serious implications for both soil ecosystems and human health.
Despite being a key radioactive material, uranium poses significant health risks due to its chemical toxicity to the kidneys, bones, and cells. As a result, both the U.S. Environmental Protection Agency and the World Health Organization recommend allowing and advocating for uranium concentrations in wastewater to be below 30 μg/L.
The Korea Institute of Civil Engineering and Building Technology (KICT) has conducted research on a nano-material-based adsorption process to efficiently remove uranium wastewater extracted from actual radioactive-contaminated soil. They have also proposed its applicability to prevent secondary environmental pollutions.
Engineered protein filaments originally produced by bacteria have been modified by scientists to conduct electricity. In a study published recently in the journal Small, researchers revealed that protein nanowires—which were modified by adding a single compound—can conduct electricity over short distances and harness energy from moisture in the air.
“Our findings open up possibilities for developing sustainable and environmentally friendly electrical components and devices, based on proteins,” says Dr. Lorenzo Travaglini, lead author on the paper. “These engineered nanowires could one day lead to innovations in energy harvesting, biomedical applications and environmental sensing.”
Developments in the interdisciplinary field that combine protein engineering and nanoelectronics also hold promise for developing cutting-edge technologies that bridge the gap between biological systems and electronic devices.
