A neuromorphic supercomputer called DeepSouth will be capable of 228 trillion synaptic operations per second, which is on par with the estimated number of operations in the human brain.
How do magnets work?

For centuries, people have been mystified by magnets and wondered how they worked. In this video, Fermilab’s Dr. Don tells us how.

Science Is Becoming Less Human
Posted in robotics/AI, science
AI will of mostly taken over science by around 2035. w/ A LOT of foot stompin about science needs a human touch lol.
AI is accelerating the pace of discovery—but at what cost?
The software could cut delays in diagnosis and offer the “ultimate second opinion”, researchers have said.
The AI company DeepMind claims it has developed a way to harness the creativity of chatbots to solve mathematical problems while filtering out mistakes.
There’s a new global news network launching in 2024 which completely ditches humans for AI-generated newsreaders – and they’re showing off some superhuman capabilities that make it very clear: the days of the human news presenter are numbered.
Channel 1’s photorealistic news anchors come in all shapes and sizes. They can all speak more or less any language, while evoking the stiff, formal body language familiar to anyone that still watches news on the TV. They’re even capable of making news-anchor-grade attempts at humor.
This will be a fully personalized, localized news aggregation service; Channel 1 isn’t using AI to produce its own news stories. Instead, it’ll round up human reporting by “trusted sources” around the world, then re-package it as fully narrated, hosted and edited news stories that’ll run together in a list curated to your personal topics of interest, complete with footage and images from the event, like a personal TV station.
Bill Faloon our Co-Founder will give a presentation in Remembrance of People Currently in Suspension.\
Join us at 6:00 pm EST in Zoom for our Perpetual Life Hybrid Party live from our new location at 950 South Cypress Road in Pompano Beach, FL, or socialize with Immortalists from Around the World, hosted by Tonya Scholz and Rudi Hoffman via Zoom. \

The judicious shaping of a tube of plasma by one laser enhances the properties of electron bunches accelerated by another.
The idea was first proposed in 1979: use a laser to separate a plasma’s electrons from its ions, thereby creating an electric field that accelerates electrons to giga-electron-volt (GeV) energies over a few micrometers. Turning that idea into useful devices requires bestowing electrons with not just high energy but also with a tight spread in energy. Now a team led by Simon Hooker of Oxford University, UK, has demonstrated a plasma-preparation technique that yields 1.2 GeV electrons with an energy spread of 4.5% [1]. Although that performance falls short of conventional accelerators, further improvement is possible.
In general, the more intense the laser and the denser the plasma, the greater the electron acceleration. But if the laser–plasma interaction is pushed up into the nonlinear regime, the acceleration becomes unruly. Working at lower intensities and densities requires sustaining the acceleration for longer. It also requires that the electrons in the lowest-density part of the plasma are accelerated first. That way, the exiting electrons form a tight bunch.
Closing a Gap in Nuclear Theory

Theoretical descriptions of the first excited state of helium-4 are now consistent with experimental data.
Elucidating human contact networks could help predict and prevent the transmission of SARS-CoV-2 and future pandemic threats. A new study from Scripps Research scientists and collaborators points to which public health protocols worked to mitigate the spread of COVID-19—and which ones didn’t.
In the study, published online in Cell on December 14, 2023, the Scripps Research-led team of scientists investigated the efficacy of different mandates—including stay-at-home measures, social distancing and travel restrictions —at preventing local and regional transmission during different phases of the COVID-19 pandemic.
They found that local transmission was driven by the amount of travel between locations, not by how geographically nearby they were. The study also revealed that the partial closure of the U.S.-Mexico border was ineffective at preventing cross-border transmission of the virus. These findings, in combination with ongoing genomic surveillance, could help guide public health policy to prevent future pandemics and mitigate the new “endemic” phase of COVID-19.
