US experiment reveals diamond melting behavior under high pressure, potentially advancing inertial confinement fusion research

US experiment reveals diamond melting behavior under high pressure, potentially advancing inertial confinement fusion research

2026-08-17

Researchers at Lawrence Livermore National Laboratory published a new study in Nature Physics documenting the melting process of diamond at pressures approximately three times greater than those at Earth's core. The experiments showed that under high-pressure conditions, diamond floats in liquid metallic carbon, similar to how ice floats in water. This finding helps improve inertial confinement fusion experimental models and provides new evidence for understanding the potential "diamond rain" phenomenon inside ice giant planets such as Neptune and Uranus. The latest melting experiments confirmed that under high pressure, diamond floats in liquid metallic carbon, just as ice floats in a glass of water.

Controlled Nuclear Fusion Specialized Power Supply Industry Matchmaking Conference Held in Hefei High-tech Zone

2026-08-17

On August 14, a major industry event focused on the fusion core equipment track — the "Fusion Power Source, Chain Linkage, New Journey" Controlled Nuclear Fusion Specialized Power Supply Industry Matchmaking Conference — was held at the Zhongke Hefei Technology Innovation Engineering Institute. The conference was guided by the Hefei High-tech Zone Science and Technology Bureau, co-hosted by the USTC Silicon Valley Service Platform and the Fusion Financial Institutions Alliance, organized by Hefei Tai'a Fusion Technology Co., Ltd., Science Island Hefei Technology Innovation Engineering Institute Co., Ltd., and the Anhui Science, Technology and Industry Integration Innovation Association, with exclusive support from the Bank of China Hefei Branch. Specialized power supplies are the core power hub supporting the stable operation of controlled fusion devices, and are also key hardware for achieving stable plasma confinement and advancing self-sustaining fusion reactions. In various fusion experimental devices, the overall cost of the power supply system accounts for a considerable proportion. Currently, the global controlled nuclear fusion industry has entered a stage where engineering demonstration and commercialization breakthroughs proceed in parallel, and the industry is facing a window of opportunity for development. However, the industry still faces practical development challenges such as long cycles for translating scientific research into technology applications, lack of information exchange between upstream and downstream supply and demand, and heavy R&D burdens on sci-tech innovation and manufacturing enterprises.

SLAC team observes progressive melting of copper under extreme heat in real time

SLAC team observes progressive melting of copper under extreme heat in real time

2026-08-15

Researchers at the SLAC National Accelerator Laboratory, under the U.S. Department of Energy, and their collaborators used the Mega-electron-volt Ultrafast Electron Diffraction (MeV-UED) facility to observe in real time the melting process of copper atoms under extreme temperatures. The study was published in Nature Communications. Future fusion power plants will need to replicate fusion reactions that occur inside stars here on Earth. The core plasma can reach temperatures of hundreds of millions of degrees Celsius, while surrounding structural materials must withstand sudden, intense thermal shocks. Copper and its alloys, owing to their excellent thermal conductivity, are considered capable of serving as "heat sinks" in fusion systems...

Neutron and X-ray tomography reveal hydrogen-rich regions in Martian meteorite "Black Beauty"

An international team of researchers from Denmark, Sweden, and Switzerland recently conducted a three-dimensional non-destructive analysis of a slice of the Martian meteorite NWA 7034 "Black Beauty" using neutron tomography and X-ray tomography, discovering macroscopic hydrogen-rich regions within it. The study suggests that these hydrogen-rich features provide evidence of early water-rock interactions on Mars. The findings have been published in Geophysical Research Letters. Black Beauty is a brecciated meteorite from Mars that was ejected into space by an impact event and eventually landed in the Sahara Desert in Morocco. Weighing approximately 320 grams, the meteorite contains material up to 4.48 billion years old, making it one of the oldest known Martian crustal fragments...

Fermilab Muon g-2 Experiment Sets New Direct Detection Limit on Muon Electric Dipole Moment

On August 12, 2026, the Muon g-2 Collaboration announced that a new analysis based on 25% of the data from the Muon g-2 experiment at the U.S. Department of Energy's Fermi National Accelerator Laboratory has produced the most sensitive direct measurement of the muon's electric dipole moment to date. The results show that if a muon electric dipole moment exists, its magnitude is below the current detection threshold of the experiment. The muon electric dipole moment values measured by Fermilab across different data-taking periods were compared with previous results from Brookhaven National Laboratory. The combined Fermilab value is consistent with zero (no observation). Although the experiment uses positive muons, results are typically reported for negative muons, which reverses the sign of the measured value...

FDG PET/CT Enables More Precise Identification of Multiorgan Involvement in Brazilian Paracoccidioidomycosis

A study conducted by researchers at the Brazilian CEPID CancerThera center shows that molecular imaging with fluorodeoxyglucose (FDG) PET/CT can detect systemic lesions of paracoccidioidomycosis (PCM) more sensitively than conventional staging methods, helping to reassess the extent and severity of the disease. The findings were published in Clinical Infectious Diseases. Paracoccidioidomycosis is a systemic fungal disease caused by inhalation of fungal spores of the Paracoccidioides genus, with significant clinical and epidemiological importance in Brazil. Often referred to as "coffee planter's disease," it primarily affects the lungs but can also spread to multiple organs via lymphatic and hematogenous routes. Conventional staging typically relies on...

CMS Experiment Advances Higgs Boson Pair Search with New Data

The CMS Collaboration has recently announced new progress in the study of Higgs boson pair production. The study is based on proton collision data at a center-of-mass energy of 13.6 TeV recorded by the CMS detector from 2022 to 2024, focusing on the search for processes where one Higgs boson decays to a bottom quark–antiquark pair and the other decays to a τ lepton–antitau pair, namely the HH→bbττ channel. Since the discovery of the Higgs boson in 2012, the CMS and ATLAS Collaborations have continuously measured the interactions of the Higgs boson with other Standard Model particles, and the results so far remain generally consistent with Standard Model predictions. In contrast, the “self-coupling” among multiple Higgs bosons...

Russian Researchers Develop Highly Sensitive Radio Astronomy Sensor for Axion Dark Matter Detection

Researchers from the Institute for Physics of Microstructures of the Russian Academy of Sciences and Nizhny Novgorod State Technical University have developed a radio astronomy sensor whose sensitivity is reportedly two to three times higher than that of existing international counterparts, and it has been granted a Russian patent. The device is designed for detecting weak electromagnetic radiation signals and can be used in frontier physics experiments such as cosmic microwave background radiation studies and axion dark matter searches. The researchers explain that this type of detector is essentially an electromagnetic radiation receiver. When electromagnetic radiation strikes the sensitive element, the electron temperature rises, thereby altering the recorded signal. To improve detection sensitivity, the research team introduced a thin hafnium layer into the structure, which acts as a thermal...
