Published 7 October 2025
The discovery of a new, 𝑒+𝑒− reaction channel in deuteron-deuteron (DD) fusion at very low energies might have major implications for understanding primordial and stellar nucleosynthesis, where electron-positron reaction channels are typically not considered. It could also enable research on metal hydride fusion, potentially paving the way for the design and construction of next-generation fusion energy sources. Following the first experimental indications of electron emission, we present here an extensive experimental study confirming emission of high-energy electrons from DD reaction at very low energy. A simultaneous use of Si charged particle detectors of different thicknesses and large-volume NaI(Tl) and HPGe detectors has allowed the determination of the branching ratios between emitted protons, neutrons, and 𝑒+𝑒− pairs for deuteron energies down to 5 keV.
The high-energy positrons could be unambiguously detected by their bremsstrahlung spectra and annihilation radiation, supported by the geant4 Monte Carlo simulations. The theoretical calculations, based on a destructive interference between the threshold resonance and the known broad resonance in 4He, agree very well with experimentally observed increase of branching ratios for lowering projectile energies. The partial width of the threshold resonance for the internal 𝑒+𝑒− pair creation should be at least 10 times larger than that of the proton channel.

3.) New Hydrogen Fusion Energy (NHFE) soon to start field trials:
We have successfully demonstrated the generation of a practical amount of heat through nuclear fusion using light hydrogen as fuel. This paves the way for the societal implementation of this technology to help mitigate global warming and achieve self-sufficiency in low-cost energy. Our project has been selected for funding under the Aichi Prefecture’s “2025 New Aichi Creative R&D Subsidy Program” and the Toyota City’s “2025 Toyota City Manufacturing Innovation Subsidy Program.”
This funding will enable us to accelerate our efforts to improve heat dissipation performance. Some newer NHFE heat power performance data will be disclosed at ResearchGate in near future. We will begin the field test of our heating system this winter. The new nuclear fusion reaction principle (TSC theory) is the result of 35 years of research on room-temperature nuclear fusion by Professor Emeritus Akito Takahashi of The University of Osaka.

Recently on the forum, one of our Verified Members (gio06) provided us this: “Witness report of a Low Energy Anomalous Phenomena experiment producing radioactive material (deemed to be tritium from other independent analyses I was provided) with extremely low energy input“… by Maurizio Maggiore
“The author has been invited to a demonstration of an upgraded version of the apparatus used in the experiment presented at ICCF24[1] by Ing. Guido Parchi of Prometheon on behalf of the inventor, Mr. Fabrizio Righes, CEO of TERALAB and Solitonix Srl. The latter performed in front of me the witnessed experiment with the support of Mr. Fernando Rosso, whose company (Arkea sapd) manufactured some of the elements of the apparatus. A photo recording by the author of the main events is included in this paper, while some video recordings are also available.”

2.) Review of Condensed-Matter Nucleosynthesis
Steven Krivit/Michael Ravnitzky
This article describes evidence for low-energy nuclear reactions (LENRs) in condensed matter reported by 15 independent laboratories in six countries. We summarize three types of experimental observations in LENRs that indicate nuclear reactions: anomalous isotopic abundances, nuclear transmutations from one element to another, and tritium production. LENRs are produced under special conditions on the surfaces of metallic hydrides or deuterides. Methods used include electrolysis, electrolytic co-deposition, gas-absorption and gas-desorption. The evidence suggests a new area of science that encompasses condensed-matter physics, nuclear physics, surface physics, metallurgy, materials science, nanotechnology, and chemistry. This research was incorrectly labeled by the news media in 1989 as “cold fusion.” Subsequent experimental results and theoretical work do not support the fusion hypothesis.
Further, these newer insights help to explain a series of experimental anomalies reported a century ago. The Widom-Larsen theory, introduced in 2006, based on standard physics, provides the first reasonable explanation for LENRs. Rather than fusion, this theory explains the phenomena based on coherent, many-body, collective effects and neutron-catalyzed electroweak interactions. It explains how macroscopically low levels of external input energy can lead to microscopically high levels of localized energy. As such, the theory suggests that, in some condensed-matter conditions, LENRs may produce effects analogous to stellar neutronization—the production of neutrons from free electrons and protons—a phenomenon usually associated with the cores of dying stars. Neutron-capture and decay mechanisms then lead to nuclear transmutations and isotopic anomalies resulting in condensed-matter nucleosynthesis. LENRs have the potential to produce useful energy, synthesize elements and stable isotopes, and mitigate harmful radioisotopes from nuclear fission.

3.) Dr. Edmund Storms has been kind enough to provide us a preprint of his new paper:
The nature of transmutation and its relationship to
low-energy fusion of deuterium
Edmund Storms
Santa Fe, NM
Elements that are absent in a material have been found to form during the low-energy
fusion of deuterium. This transmutation process can be explained by assuming the fusion
reaction involving deuterium emits a 4H particle with enough kinetic energy to produce
the reaction AAZ + 4H → (A+2)A(Z+1) + 2n when it encounters a nucleus in the surrounding
chemical environment. This proposed mechanism is examined in light of several
published studies.

A Rebrand Breathes Life Into Cold Fusion Research in
Japan
September 19, 2025
“The goal is to stock 900 sheets in a reactor much bigger than what has already been achieved. Theoretically, Yoshino says, as many as 10,000 sheets could be stacked. Eventually, Clean Planet wants to develop heat modules for the industrial, commecial, transportation and residential sectors. “The limit would be that if it gets too hot, it will break some of the parts (of the reactor) and other things like gaskets and the heater itself so we try not to exceed 1,400 structures. That’s where the nickel would start to melt.””
Professor Raj Pala from the Indian Institute for Technology at Kanpur recently gave a talk on Hydrino at the 26th International Conference on Condensed Matter Nuclear Science (ICCF26) in Japan. The talk has been posted to YouTube and I encourage everyone to watch it.
The talk is significant because a respected professor from an excellent university with impeccable credentials in his field is publicly taking Dr. Mills’ GUTCP and Hydrino hypothesis very seriously and urging his fellow scientists to do the same.
Professor Pala currently runs a lab within the Department of Chemical Engineering and Materials Science at IITK. His educational background is as follows:
“Successful cold fusion on a laboratory table”: an experiment revives the hope of clean and unlimited nuclear energy
Cold fusion, long discredited, is resurfacing with a promising new experiment that could revolutionize our approach to energy.

Community Notes:
1.) ISCMNS Leadership Changes:
To the President, Executive Committee and all members of the ISCMNS.
With great sadness I am tendering my resignation as Honorary Secretary and Acting Treasurer of the ISCMNS.
My reasons are many, some private and some public, but the public ones are as follows. I have been diagnosed with cancer of the esophagus, and I am currently being pump-fed pink goo through a naso-gastric tube. This kind of cancer is a serious health problem, and all being well I am due some very savage surgery to remove the affected part of my esophagus and reconnect it. Hopefully it has been detected early and there are no currently visible secondaries, but even as the Exec Committee meets I will be having a PETscan in a central London hospital as a last check of many.
The other public reason is my work on green chemistry for Paragon Resources UK – the foundations of which go back almost 20 years. I am technical head of what will hopefully become a £300M web of chemical plants in the UK and EU, producing many different things we need – everything from hydrogen and ammonia to detergents, drain cleaner and toxin-free battery-fire extinguishers. Low energy processes all of the with no ‘forever chemicals’ used or produced. putting nothing up the chimney, and nothing down the drain, many of the products made from the by-products of other parts of the process. As you might understand I am keen to see it through, not just for money, but for love of science and its many possibilities- the very thing that brought me to the ISCMNS.
I will hope to carry on my duties until the end of October, by which time nominations for a replacement will be in hand and we can have a vote – and perhaps an online poll of all members.
My grateful thanks to all members for letting me look after your interests, I have done my best to leave the ISCMNS in good shape.
Best Wishes. Alan Smith.
CEO / Hon Sec ISCMNS.
Chief Scientist Paragon Resources UK
-In addition, sadly Lynn Bowen has also resigned her position as President of the ISCMNS.
We on the Forum Team pray for our friend and colleague Alan Smith’s speedy recovery.
