LIGO and Virgo may have detected cosmic pressure waves, not gravitational waves.

The JUNO detector is now live—marking a major milestone in neutrino physics. Situated 700 meters underground in China, between the Yangjiang and Taishan nuclear plants, this large-scale liquid scintillator experiment is expected to detect ~40-60 neutrinos/day for at least the next 10 years. With ~43,212 photodetectors and ultra-clean shielding to reduce background noise, JUNO aims to clarify the neutrino mass hierarchy and oscillation behavior of the three neutrino flavours. The data could have wide-ranging implications for particle physics, cosmology, and even earth science. Full article: https://lnkd.in/e9kbGUqp

Physicists Measure the ‘Heartbeat’ of a Single Atom in Real Time For the first time ever, physicists at Delft University of Technology directly observed the nuclear spin—the magnetic core—of a single titanium-49 atom flipping between states in real time, thanks to an advanced pulsed STM (scanning tunneling microscope) technique. What’s more, the spin remained stable for about 5 seconds, far longer than typical electron spins (~100 nanoseconds), enabling a single-shot readout with up to 98% fidelity—a major leap for quantum control and atomic-scale sensing. This breakthrough moves nuclear spins into the spotlight as reliable qubit candidates, offering new pathways for quantum sensing, simulation, and engineering at the atomic level. #QuantumPhysics #Qubits #AtomicSensing #QuantumResearch #STM #QuantumBreakthrough

A bold concept from MIT: using quantum optics and atomic physics to propose the first “neutrino laser.” The idea is to super-cool a radioisotope gas like rubidium-83 into a Bose-Einstein condensate, then leverage superradiance so atoms decay collectively, producing a coherent, directional burst of neutrinos. This would accelerate decay compared to the normal timeline — a million-atom cloud could emit neutrinos in minutes instead of months. Potential applications include new ways to study neutrino properties, underground or deep space communication unaffected by most matter, and perhaps even novel imaging or detection technologies. While still theoretical and facing substantial experimental hurdles (maintaining coherence, safety, handling radioactive material), this proposal represents a fascinating intersection of quantum, atomic, and nuclear physics.

Why Half-Life Calculations Are Essential in Modern Industries? As professionals in healthcare, energy, and research, understanding radioactive decay isn't just academic—it's critical for: ✅ Medical imaging: PET scans rely on precise half-life timing ✅ Archaeological dating: Carbon-14 dating revolutionized historical research ✅ Nuclear safety: Waste management depends on decay predictions ✅ Space exploration: RTGs power deep space missions for decades The mathematics might seem complex, but the applications directly impact patient care, environmental safety, and scientific discovery. Whether you're scheduling radiotherapy treatments or planning nuclear waste storage, half-life calculations ensure precision and safety. Key insight: Different isotopes decay at vastly different rates—from microseconds to billions of years. This diversity enables targeted applications across industries. https://lnkd.in/dcvHc7Yi What's your experience with radioactive materials in your field?

The Jiangmen Underground Neutrino Observatory (JUNO) has officially begun operations as of 26 August 2025, marking the launch of the world’s largest neutrino detector deep beneath southern China. After more than a decade of development, the colossal 20,000‑ton liquid scintillator detector has been filled and is now actively taking data, with its initial performance exceeding expectations. Positioned 700 meters underground and situated 53 km from nearby nuclear power plants, JUNO is uniquely designed to resolve the long-standing neutrino mass-ordering mystery with unprecedented precision, while also exploring neutrinos from the Sun, Earth, supernovae, and beyond. Backed by a global collaboration of over 700 scientists from 74 institutions across 17 countries, JUNO is poised to transform our understanding of particle physics and pave the way for future breakthroughs—from probing exotic physics to informing supernova models. https://lnkd.in/eqRrCwf7

The MARATHON experiment has achieved the most precise measurement to date of the neutron-to-proton structure function ratio, providing new insights into the momentum distribution of quarks within nucleons. Utilizing advanced techniques and rare tritium targets, the experiment also delivered the first measurement of the EMC effect in tritium and helium-3 mirror nuclei. These results are expected to refine models of nucleon structure and quantum chromodynamics, offering significant implications for nuclear and particle physics. Future investigations at Jefferson Lab aim to further advance understanding of nucleon dynamics and subatomic interactions.

Taking the pulse of an atomic nucleus. Researchers led by Evert Stolte and Jinwon Lee of the Delft University of Technology have measured in real time the pulse of an atom as it evolved between quantum states. The team used a scanning tunneling microscope to observe electrons as they moved synchronically with the nucleus of an atom of titanium-49, and estimated thanks to it the duration of the core's magnetic beat, the back and forth change between quantum states, in isolation. The findings have been published in Nature Communications (21 August, 2025). https://lnkd.in/dw-in6SP #physics #physicsnews #quantumphysics #quantumtunneling #atomicphysics #nuclearphysics #titanium #titanium49

What if nuclear masses could be explained without any adjustable parameters? For decades, nuclear physics has relied on semi-empirical formulas (such as Weizsäcker’s). They describe nuclear binding energies with remarkable accuracy… but only at the cost of coefficients fitted to experimental data. In other words: these models describe, but they do not explain. 👉 With the Theory of the Wave Universe (TUO), we propose a radically different approach: Each term of the binding energy formula (volume, surface, Coulomb, asymmetry, pairing) is derived directly from fundamental constants and from a vibrational invariant of the vacuum. No empirical parameters. No a posteriori fitting. Predictions become fully falsifiable. 🔬 Results: For stable nuclei such as calcium (⁴⁰–⁴⁸Ca) and nickel (⁵⁸–⁶⁴Ni), deviations from experimental masses are typically below 0.3 MeV per nucleon. For exotic isotopes such as ⁶⁰Ca or ⁷⁸Ni, TUO provides direct predictions, testable by upcoming nuclear physics experiments. Larger deviations for very light or very heavy nuclei point toward expected refinements (compactness, deformation), confirming the robustness of the approach. > But the stakes go far beyond nuclear physics: By describing binding as a vibrational resonance of the vacuum, TUO opens a path to connect microscopic quantum physics (spins, fields, coherence) and macroscopic gravitation. 💡 In short: TUO does not replace the Standard Model—it extends it, just as relativity extended Newton. It offers a more fundamental vision: masses are not fitted, they emerge from a universal dynamics of the vacuum. #Physics #Research #Innovation #TUO #NuclearPhysics #Science

The search for dark matter and other elusive cosmic relics receives a significant boost from new research demonstrating a pathway to dramatically enhance detection rates using the collective behaviour of atomic nuclei. Marios Galanis, from the Perimeter Institute for Theoretical Physics, Onur Hosten of the Institute of Science and Technology Austria (ISTA), and Asimina Arvanitaki, also at the Perimeter Institute, alongside Savas Dimopoulos from the Leinweber Institute for Theoretical Physics at Stanford, present a protocol that achieves an unprecedented level of signal amplification. Their work leverages a process akin to superradiance, where the combined effect of numerous nuclear spins dramatically increases the interaction with weakly interacting particles, potentially revealing the existence of dark matter candidates like axions and dark photons. https://lnkd.in/eeV5Y5zy
