Hologram technology where ‘light becomes the key’ enables hard-to-copy security
A new type of hologram technology has been developed that uses the motion of light as a key, revealing information only under specific conditions. This is gaining attention as a novel approach that can simultaneously overcome the limitations of existing optical communication and security technologies.
A Token of Our Imagination: The Invisible Economy Powering GenAI
Ever wonder what actually happens inside the AI after you hit “Enter”?
You type a prompt into your favorite generative AI, and within seconds, your screen fills with exactly what you asked for—whether it’s a quarterly report or a cinematic image of a cyberpunk golden retriever. It feels like absolute magic.
But behind that seamless curtain lies a bustling, microscopic economy running entirely on a digital currency you’ve probably heard of but might not fully understand: the token.
Most of us only ever see the input and the output. We don’t see the internal cash register ringing, the mathematical gymnastics, or the sprawling “assembly line” churning through billions of calculations.
What actually happens between the moment you hit send and the moment your final masterpiece appears? In my newest blog post, I peel back the curtain to trace the fascinating journey of an AI token.
I break down this invisible economy—from the “toll booth” of the input phase to the heavy lifting of the output phase—and show you exactly how the machine balances the books.

Post Materialist Reality: Why Psionics & NHI Consciousness Phenomena are rational and not “Woo”
A lightning fast catchup on the latest in foundational physics theories, in light of recent news conserning UAP, NHI, and psionics
AI Is Now Improving Itself
In 1965, a mathematician who worked alongside Alan Turing wrote a single
paragraph that has haunted AI research ever since. He predicted that one
day, a machine would learn to improve itself, and that everything after
that point would change.
Sixty years later, that loop is starting to close.
In this video, we trace how AI got here: from I.J. Good’s 1965 prediction.
to AlphaGo Zero teaching itself Go in 72 hours, to AlphaEvolve cracking a
math problem that had stood unbeaten for 56 years, and then quietly
speeding up the training of the very model that runs it. We look at the
data behind the trend (autonomous AI task length is doubling every 7
months), the walls AI keeps running into (compute, data, energy), and what
the people building this technology are actually saying about how close
we are.
This video is an honest look at what \.
Biodiversity and biogeography of the multi-kingdom cancer microbiome
Now online! A host-filtering and decontamination pipeline was benchmarked and applied to 16,369 tumor genomes, providing a high-resolution atlas of the cancer microbiome. Although most cancer types lacked a detectable microbiome, orodigestive cancers harbored complex multi-kingdom microbial communities that varied by site, subtype, and somatic mutation burden, linking the tumor microbiome to host phenotype and tumor genomic context.
