Galaxies are not islands in the cosmos. While globally the universe expands—driven by the mysterious “dark energy”—locally, galaxies cluster through gravitational interactions, forming the cosmic web held together by dark matter’s gravity. For cosmologists, galaxies are test particles to study gravity, dark matter and dark energy. Go to Source Liquid-like molecular dynamics explain solid-state battery material’s superionic transport abilitiesResearchers at Duke University have uncovered the molecular inner workings of a material that could underpin next-generation rechargeable batteries. Go to Source The report states that 147 officers lost their lives while serving in 2024, up from 118 in 2023; traffic-related fatalities saw the largest increase, rising by 48% Go to Source A study published in The Astrophysical Journal Letters, introduces a newly defined “filament channel” function. This new function provides a novel theoretical foundation for predicting solar eruptions by determining whether new emerging flux (NEF) can trigger instability in solar filaments. The study was led by Prof. Lin Jun from the Yunnan Observatories of the Chinese […] An international team of astronomers have investigated a large Galactic supernova remnant designated G278.94+1.35. Results of the study, published Dec. 30 on the pre-print server arXiv, shed more light on the properties of this remnant. Go to Source Quantum physics is a very diverse field: it describes particle collisions shortly after the Big Bang as well as electrons in solid materials or atoms far out in space. But not all quantum objects are equally easy to study. For some—such as the early universe—direct experiments are not possible at all. Go to Source […] Numerous memory types for computing devices have emerged in recent years, aiming to overcome the limitations imposed by traditional random access memory (RAM). Magnetoresistive RAM (MRAM) is one such memory type which offers several advantages over conventional RAM, including its non-volatility, high speed, increased storage capacity and enhanced endurance. Go to Source […] Quantum computing holds the promise of outperforming classical computing on some optimization and data processing tasks. The creation of highly performing large-scale quantum computers, however, relies on the ability to support controlled interactions between qubits, which are the units of information in quantum computing, at a range of distances. Go to Source […] The upcoming U.S.–India NISAR (NASA-ISRO Synthetic Aperture Radar) mission will observe Earth like no mission before, offering insights about our planet’s ever-changing surface. Go to Source SpaceX sent up the second launch of the year from the Space Coast on Monday afternoon. Go to Source It is the largest and most famous Sphinx, situated at the Giza Plateau adjacent to the Great Pyramids of Giza on the west bank of the Nile River, it has puzzled Egyptologists and researchers for centuries. Here we bring you some facts about this mysterious construction in Egypt: The Sphinx was carved from […] Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations, or modes, is a toroidal distribution of currents, which results in the formation of vortex-like structures. Go to Source Amazon founder Jeff Bezos’s Blue Origin will launch its first orbital rocket “no earlier than Friday”, it said, a pivotal moment in the commercial space race currently dominated by Elon Musk’s SpaceX. Go to Source Physicists have proposed a solution to a long-standing puzzle surrounding the GD-1 stellar stream, one of the most well-studied streams within the galactic halo of the Milky Way, known for its long, thin structure, and unusual spur and gap features. Go to Source Metrology serves as the cornerstone of modern industry, providing the key standards by which we measure the world. Optical metrology, in particular, has historically leveraged the notion of interference, essentially unchanged since the days of Thomas Young more than 200 years ago. However, can one glean more information by extrapolating the concept of fringes to […] |
