The hottest Fusion Substack posts right now

Big advances in clean energy are moving from lab to grid. Gigawatt‑hour iron‑air batteries are being deployed for multi‑day storage and startups are pursuing stellarator fusion plants, both pointing to more reliable, decarbonized power and new manufacturing jobs.
Medical research is producing transformative, non‑traditional therapies. Phase‑3 psilocybin trials show strong results for treatment‑resistant depression and other studies suggest benefits for chronic conditions like post‑treatment Lyme, while vitamin B2/B3 genomics identified a simple, life‑saving therapy for NAXD in animal models.
The internet economy is accelerating and reshaping commerce and payments. Fast growth in new businesses, app activity, and stablecoin payment volume, plus concepts like agentic commerce, suggest rising momentum — but widespread progress will depend on regulatory and permissioning systems.

Zakir Hussain was a master of the tabla, a traditional Indian drum. He started learning at just three years old from his famous father, showing early talent.
Hussain blended classical tabla music with modern influences and worked with big names like George Harrison and the Grateful Dead. He made the tabla more popular by bringing it to new audiences.
His love for music started as a baby when his father sang tabla rhythms to him. This deep connection shaped his incredible career in music.

Human civilization is driven by the type and availability of energy sources, dictating growth, quality of life, and societal scale.
Energy originates from nuclear reactions and its evolution through fusion and fission have shaped both natural processes and human advancement.
Fusion energy holds the potential to revolutionize energy production by offering a clean, abundant, and safe alternative to traditional sources.

Altman is seeking an unprecedented $7 trillion to invest in AI infrastructure, which includes developing GPUs, energy supply improvement, and expanding data center capacity.
The $7 trillion investment is meant to propel technological advancements to a level comparable to the impact of the Industrial Revolution, focusing on long-term projects over decades rather than immediate outcomes.
Despite the astronomical sum, the $7 trillion investment may not seem as excessive considering the potential growth of the global economy and the transformative nature of the projects Altman aims to support.

90 odd power plants in the country are n-U fusion reactors, creating electricity with an engineering gain of about 18.
Operators of these fusion plants are advised to apply for a Section 30 license from the NRC quickly or contact their state regulatory agency if in an Agreement State.
The breakthrough in fusion we've been waiting for involves the significant engineering gains of n-U fusion reactors, surpassing other fusion concepts in terms of proven efficiency.

Fusion faces difficult technical challenges like damage to the first wall, intense heat transfer, and high maintenance due to activation of materials.
Achieving economic viability in fusion is a major hurdle, with immense parasitic loads and a fusion gain ratio that can be a significant challenge to achieve.
Standard fusion processes like using deuterium and tritium result in energy losses due to the need for high quality energy input, which makes fusion less self-sustaining than fission.

Zakir Hussain was a master tabla player known for blending various music styles. He mixed Hindustani classical music with other genres like jazz and rock, creating a unique sound.
His upbringing was unique because he received support from his family, including his mother and wife, to explore different musical paths. This openness allowed him to learn from diverse musical backgrounds and artists.
Zakir's concerts were not just performances; they were experiences. He had a special way of connecting with audiences, making them feel engaged, whether he was playing solo or with other musicians.
