Ian Hutchinson’s concerns for existential risk after minute 42.


Ian Hutchinson is a nuclear engineer and plasma physicist at MIT. He has made a number of important contributions in plasma physics including the magnetic confinement of plasmas seeking to enable fusion reactions, which is the energy source of the stars, to be used for practical energy production. Current nuclear reactors are based on fission as we discuss. Ian has also written on the philosophy of science and the relationship between science and religion.

“Brand New Paradigm” — Scientists Discover How Human Eggs Remain Healthy for Decades

Posted by in categories: biotech/medical, genetics, nuclear energy

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).

Can a Seattle Start-Up Launch a Fusion Reactor Into Space?

Posted by in categories: military, nuclear energy, satellites, sustainability

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.

Center for Radiation Chemistry Research takes a forgotten science into the future

Posted by in categories: chemistry, nuclear energy, science, sustainability

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.

EDF to restart all its nuclear reactors this winter

Posted by in category: nuclear energy

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.

1.7 billion years ago, Earth had a natural nuclear reactor

Posted by in categories: nuclear energy, space

Planets can create nuclear power on their own, naturally, without any intelligence or technology. Earth already did: 1.7 billion years ago.
