Researchers at SLAC used the MeV-UED electron camera to image copper as it was heated with laser pulses, revealing a gradual melt and maintained lattice order past the predicted superheating limit under dynamic pressure — a result that upends older models and improves fusion-material simulations.
Trump Media & Technology posted a $238 million loss in Q2 as it pivots back toward social media and expands into crypto and online betting under new CEO Kevin McGurn. It launched Truth API to sell early access to Truth Social posts to Wall Street traders for $60,000–$100,000 a month (10 customers) while continuing a nuclear-fusion venture with TAE Technologies; revenue rose 89% to $1.7 million, but the company carries about $1 billion in debt, with over $400 million in cash and roughly $1.2 billion in bitcoin.
German researchers have demonstrated silver-doped zeolites that selectively separate protium, deuterium and tritium—the three hydrogen isotopes—via interactions with silver ions in the crystal and staged release by heating. In tests, the output shifted to a 1:41:175 ratio (protium:deuterium:tritium), the first three-way separation of hydrogen isotopes in a solid porous material. This advances closed‑loop fuel recycling for commercial fusion and shows radiation tolerance, though long‑term operation remains under study.
Researchers used neon plasma at 800°C inside a vacuum chamber to clean contaminated porous tungsten wall tiles inside a nuclear fusion reactor. The treatment removes bound carbon and oxygen and drives surface purity from 0% to 87% metallic tungsten, happening entirely within the reactor to avoid air exposure and preserve liquid-metal channels, a step that could streamline in-situ maintenance for future fusion power.
US researchers at UC Davis and Berkeley Lab found that surrounding host metals can dramatically boost low-energy deuterium fusion, with fusion rates plateauing below 2.5 keV and, in some samples, increasing by up to a quintillion-fold versus vacuum; the effect is attributed to electrons and structural defects in the host metal shielding Coulomb repulsion, opening a new materials-driven approach to fusion and potentially enabling compact neutron generators and new modeling tools like DuctGPT.
Researchers have shown for the first time that the polarization (spin alignment) of particles is preserved during laser-plasma acceleration, a breakthrough for compact fusion research. Using pre-polarized Helium-3, the PHELIX laser, and CR-39 detectors, the team demonstrated that spin alignment survives high-gradient acceleration, which can increase fusion reaction probabilities and enable new physics experiments beyond the Standard Model.
Japan’s Helical Fusion has completed a one-of-a-kind coil manufacturing machine, built with Sugino Machine, to wind high-temperature superconducting cables into spiral coils for the Helix HARUKA reactor. The device targets a key manufacturing bottleneck to enable efficient production of HTS coils, a step toward commercially viable fusion energy by the 2030s, with on-site assembly to begin later this year and demonstrations planned around 2030 to prove net electricity, steady operation, and maintainability.
Researchers in China have successfully pushed the plasma density in their EAST nuclear fusion reactor beyond the long-standing Greenwald limit, achieving higher densities while maintaining stability, which could advance fusion energy development.
Short sellers are increasing their bets against Trump media group amid a nuclear fusion merger, reflecting investor skepticism or concern over the company's prospects in this sector.
Chinese scientists have made a significant advancement in nuclear fusion research by experimentally surpassing the Greenwald density limit in a tokamak, indicating progress toward achieving sustained fusion energy, which remains years away but is a crucial step for future energy solutions.
China's EAST tokamak has achieved a groundbreaking stable high-density plasma state called the 'density-free regime,' validating a theoretical model and potentially revolutionizing fusion energy development by overcoming long-standing stability barriers.
Nuclear fusion remains a complex and uncertain investment opportunity, posing challenges not only for scientists but also for investors due to its technical difficulties and high costs, as discussed in a Financial Times article.
The article discusses concerns over a $6 billion merger between Trump Media & Technology Group and fusion energy company TAE Technologies, highlighting potential conflicts of interest for Donald Trump, whose financial stake could influence government decisions on fusion energy, raising ethical questions and fears of favoritism in the emerging clean energy sector.
Trump Media announced a $6 billion merger with fusion power company TAE Technologies, aiming to develop commercial-scale nuclear fusion energy, with plans to build the first utility-scale fusion power plant by 2026, amidst skepticism about fusion's viability as a commercial energy source.
Researchers at Japan's NIFS have observed unexpected roles of plasma turbulence inside fusion reactors, acting as both a mediator that rapidly connects different plasma regions and a carrier that transports heat, challenging existing theories and opening new avenues for improving fusion efficiency.
