A sustained, stable experiment is the latest demonstration that nuclear fusion is moving from being a physics problem to an engineering one.
According to research from the Center for Genomic Regulation (CRG) published in the journal Nature, immature human egg cells bypass a critical metabolic process believed to be necessary for producing energy.
The cells modify their metabolism to stop producing reactive oxygen species, dangerous molecules that can accumulate, damage DNA
DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Practical nuclear fusion is, famously, always 10 years in the future. Except that the Pentagon recently gave an award to a tiny startup to launch a fusion power system into space in just five.
There is no shortage of organizations, from VC-backedstartups to nation states, trying to realize the dream of cheap, clean, and reliable power from nuclear fusion. But Avalanche Energy Designs, based near a Boeing facility in Seattle, is even more ambitious. It is working on modular “micro fusion packs,” small enough to hold in your hand yet capable of powering everything from electric cars to spaceships.
Last month, the Pentagon’s Defense Innovation Unit (DIU) announced it had awarded Avalanche an unspecified sum to develop its Orbitron fusion device to generate either heat or electricity, with the aim of powering a high-efficiency propulsion system aboard a prototype satellite in 2027. The contract to Avalanche was one of two awarded by the DIU—the second going to Seattle-based Ultra Safe Nuclear for development of its radioisotope battery.
Now, as a new generation of nuclear reactor designers develop advanced molten salt reactor concepts as an alternative for providing reliable, sustainable, carbon-free power, the need for radiation chemistry has never been greater.
To meet that need, Idaho National Laboratory’s Center for Radiation Chemistry Research has developed a capability that supports the nuclear energy industry by researching radiation-induced effects in advanced reactors, fuels, coolants, materials and fuel recycling technologies while also training the next generation of radiation chemists.
PARIS, Sept 2 (Reuters) — French state-owned utility EDF will restart all its nuclear reactors, more than half of which are now closed for maintenance or technical issues, this winter, France’s Energy Minister said on Friday.
Pannier-Runacher spoke after President Emmanuel Macron held a special cabinet meeting to address the country’s energy supply situation, coordinate efforts to reduce consumption, and prepare contingency plans in case the country faces a shortage.
“EDF has committed to restart all its reactors for this winter,” Agnes Pannier-Runacher told a news conference.
Little is known about the specifications of the project, but it is edging closer.

Now, SpaceNews has reported that the reactor has passed a comprehensive performance evaluation by the China’s Ministry of Science and Technology. However, the Chinese media outlets cited by the publication have not released any technical details of the reactor.

“In June, our delegation was in South Korea, in July we went to France. Negotiations are ongoing with Chinese suppliers. Based on the results of an in-depth study of international experience, nuclear technology suppliers will be involved. I repeat, this will be an international project,” he reaffirmed, adding that the results of this experience is under study.
“In principle, the construction of a nuclear power plant is a long process, it takes about eight years. Without nuclear power, we will not be able to ensure energy security for ourselves… We will need such generation — the whole world is moving towards decarbonisation. We must move to clean technologies, and nuclear generation is the answer to the challenge of the times,” he stressed.
He stressed that the safety of NPP operation is of paramount importance. “We will choose the technology that is the safest, and those suppliers who can complete all the work in a timely manner. Related areas of our economy will also develop around this industry. There will be a big positive effect on the development of our country as a whole.”
