Nov 21st, 2025 - A dual-light, label-free microscope exposes hidden micro-to-nano activity inside living cells. A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system, from the University of Tokyo, captures both detailed structures and tiny moving particles at once, providing a more complete view of cellular behaviour. The technology is in the form of a microscope capable of detecting signals across an intensity range fourteen times ... [Read More]

Nov 19th, 2025 - A new giant detector confirms a long-suspected mystery in the particles of the Sun. Neutrinos slip through your body by the trillions each second. They rarely hit anything. They barely seem to exist. Yet a sprawling underground experiment in southern China has just shown that these "ghost particles" may be breaking the rules we thought they followed. The Jiangmen Underground Neutrino Observatory (JUNO) — now the world's largest neutrino detector — has confirmed a subtle mismatch in ... [Read More]

Nov 7th, 2025 - A team of researchers at the Max Born Institute have managed to fully characterize few-femtosecond-long light pulses tunable in the vacuum ultraviolet. These results unlock the possibility for studying valence electron dynamics of many materials in the VUV. The research is in the journal Nature Photonics . Few-femtosecond long pulses tunable across the ultraviolet (UV) are a holy grail of contemporary laser science. As most of the materials have electronic resonances in the deep- and vacuum-UV ...

Nov 7th, 2025 - High-temperature superconductivity is still not fully understood. Now, an international research team at BESSY II has measured the energy of charge carrier pairs in undoped La₂CuO₄. Their findings revealed that the interaction energies within the potentially superconducting copper oxide layers are significantly lower than those in the insulating lanthanum oxide layers. These results contribute to a better understanding of high-temperature superconductivity and could also be relevant ... [Read More]

Nov 4th, 2025 - Follow Earth on Google A team led by MIT used a simple molecule to peek inside a radium atom's nucleus. In a new study, they watched electrons in radium monofluoride pick up a tiny energy change that betrays what is happening deep in the core. The tests ran on a compact setup at CERN in Switzerland and not in a collider that stretches for miles. The result points to a practical way to map nuclear structure and to probe why the universe favors matter over antimatter. Radium monofluoride reveals ... [Read More]

Oct 30th, 2025 - Scientists have long sought to make semiconductors—vital components in computer chips and solar cells—that are also superconducting, thereby enhancing their speed and energy efficiency and enabling new quantum technologies. However, achieving superconductivity in semiconductor materials such as silicon and germanium has proved challenging due to difficulty in maintaining an optimal atomic structure with the desired conduction behavior. In a paper published in the journal Nature ... [Read More]

Oct 29th, 2025 - Carbynes, or long linear carbon chains (LLCCs), have received significant attention in recent years due to their predicted exceptional properties. However, experimentally, their properties have been hard to probe due to their low stability. To improve stability, it is necessary to encapsulate LLCCs in small diameter carbon nanotubes (CNTs). Now, researchers have developed a new method to synthesize small diameter single-walled carbon nanowires (SWCNWs), featuring high-density LLCCs encapsulated ... [Read More]

Oct 22nd, 2025 - The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow the principles of quantum physics, but those principles do not seem to be compatible with the accepted theory of gravity. For years, researchers have been proposing experiments to show whether gravity could produce a phenomenon known as quantum entanglement. Now, two theoretical ... [Read More]

Oct 20th, 2025 - In the right combinations and conditions, two-dimensional materials can host intriguing and potentially valuable quantum phases, like superconductivity and unique forms of magnetism. Why they occur, and how they can be controlled, is of considerable interest among physicists and engineers. Research published in reveals a previously hidden feature that could explain how and why enigmatic quantum phases emerge. Using a new terahertz (THz) spectroscopic technique, the researchers revealed that ... [Read More]

Oct 18th, 2025 - The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, with masses of around 100 GeV/c 2 ), primordial black holes, and ultralight axion-like particles (mass of 10 -22 to 1 eV/c 2 ). In the latter case, dark matter behaves like a wave, described by a Schrödinger equation, rather than as a collection of point particles. ... [Read More]

Oct 11th, 2025 - , Phys.org Quantum networks, systems consisting of connected quantum computers, quantum sensors or other quantum devices, hold the potential of enabling faster and safer communications. The establishment of these networks relies on a quantum phenomenon known as entanglement, which entails a link between particles or systems, with the quantum state of one influencing the other even when they are far apart. The atom-based qubits used to establish quantum networks so far operate at visible or ... [Read More]

Oct 10th, 2025 - A research team led by Prof. Lin Yiheng from the University of Science and Technology of China (USTC), collaborating with Prof. Yuan Haidong from the Chinese University of Hong Kong, succeeded in generating multipartite quantum entangled states across two, three, and five modes using controlled dissipation as a resource. Their study is in Science Advances . Multimode entanglement is a key resource in quantum computation, communication, simulation, and sensing. One of the major challenges in ... [Read More]

Oct 10th, 2025 - Follow Earth on Google Quantum computing is full of ideas that sound great until you try to build them. A new experiment now shows a way to move quantum data to exactly where it is needed. It reports 95.3 % success on that routing task in the lab, which is strong enough to take notice. Instead of treating memory as an afterthought, the team built a router that can direct a quantum signal based on a quantum address. That ability is central to designs for quantum random access memory ( QRAM ). It ... [Read More]

Oct 8th, 2025 - Reseachers uses quantum simulations to vizualize the shape of a photon emitted by a single nanoparticle -- in this case, it's lemon-shaped. When we look at the world around us, all that we see is thanks to light. It reflects, refracts, and interacts, carrying shape and depth from the objects it touches. But what about light itself? Physicists have now visualized the simulated shape of a photon (the smallest unit of light) emitted from the surface of a nanoparticle using a novel theoretical ... [Read More]

Oct 7th, 2025 - John Clarke, Michel H. Devoret, and John Martinis built an electrical circuit-based oscillator on a microchip. The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret, and John M. Martinis "for the discovery of macroscopic quantum tunneling and energy quantization in an electrical circuit." The Nobel committee said during a media briefing that the laureates' work provides opportunities to develop "the next generation of quantum technology, including quantum ... [Read More]

Oct 3rd, 2025 - By Florian Neukart, Leiden University Share What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred years, physics has rested on two foundational theories. Einstein's general relativity describes gravity as the curvature of space and time, while quantum mechanics governs the behavior of particles and fields. Each theory is highly successful within its own domain, yet combining them leads to contradictions, particularly in ... [Read More]
