Computer chips powered by human brain cells exist — but is it ethical?

Posted by in category: robotics/AI

Although the name and scenario are fictional, this is a question we have to confront now. In December 2021, Melbourne-based Cortical Labs grew groups of neurons (brain cells) that were incorporated into a computer chip. The resulting hybrid chip works because both brains and neurons share a common language: electricity.

In silicon computers, electrical signals travel along metal wires that link different components together. In brains, neurons communicate with each other using electric signals across synapses (junctions between nerve cells). In Cortical Labs’ Dishbrain system, neurons are grown on silicon chips. These neurons act like the wires in the system, connecting different components. The major advantage of this approach is that the neurons can change their shape, grow, replicate, or die in response to the demands of the system.

Dishbrain could learn to play the arcade game Pong faster than conventional AI systems. The developers of Dishbrain said: “Nothing like this has ever existed before … It is an entirely new mode of being. A fusion of silicon and neuron.”

Supercomputer Helps Understand the Physics of Thought

Posted by in categories: biotech/medical, chemistry, supercomputing

Decades of research has led to a thorough understanding of the main protein players and the broad strokes of membrane fusion for synaptic transmission. Bernard Katz was awarded the 1970 Nobel Prize in Medicine in part for demonstrating that chemical synaptic transmission consists of a neurotransmitter-filled synaptic vesicle fusing with the plasma membrane at nerve endings and releasing its content into the opposing postsynaptic cell. And Rizo-Rey’s longtime collaborator, Thomas Südhof, won the Nobel Prize in Medicine in 2013 for his studies of the machinery that mediates neurotransmitter release (many with Rizo-Rey as a co-author).

But Rizo-Rey says his goal is to understand the specific physics of how the activation process of thought occurs in much more detail. “If I can understand that, winning the Nobel Prize would just be a small reward,” he said.

Recently, using the Frontera supercomputer at the Texas Advanced Computing Center (TACC), one of the most powerful systems in the world, Rizo-Rey has been exploring this process, creating a multi-million atom model of the proteins, the membranes, and their environment, and setting them in motion virtually to see what happens, a process known as molecular dynamics.

A new breakthrough in biology allows scientists to grow food without sunlight

The researchers also optimized their electrolyzer to produce the highest levels of acetate ever produced in an electrolyzer to date. What’s more, they found that crop plants, including cowpea, tomato, rice, green pea, and tobacco, all have the potential to be grown in the dark using the carbon from acetate. There’s even a possibility that acetate could improve crop yields, though more research is required.

The researchers believe that by reducing the reliance on direct sunlight, artificial photosynthesis could provide an important alternative for food growth in the coming years, as the world adapts to the worst effects of climate change — including droughts, floods, and reduced land availability. “Using artificial photosynthesis approaches to produce food could be a paradigm shift for how we feed people. By increasing the efficiency of food production, less land is needed, lessening the impact agriculture has on the environment. And for agriculture in non-traditional environments, like outer space, the increased energy efficiency could help feed more crew members with less inputs,” Jinkerson explained.

The Age of Superhumans — Gene Editing Through CRISPR & AI

Posted by in categories: bioengineering, biotech/medical, genetics, robotics/AI

Superhumans are coming! Various technological advances in the field of medicine through AI and CRISPR are going to radically alter our understanding of what it means to be human. AI and Crispr technology have been making revolutionary changes to the field of medicine. Artificial intelligence is being applied in identification of harmful genes and treatment of disease.

Multiple new gene editing technologies in addition to artificial intelligence will cause major changes in healthcare.
The gene-editing tool CRISPR, short for clustered regularly interspaced short palindromic repeats, could help us to reprogram life. It gives scientists more power and precision than they have ever had to alter human DNA.

The Rise of Supersoldiers — How AI Changes Everything

Posted by in categories: bioengineering, biotech/medical, chemistry, genetics, health, military, robotics/AI

Artificial Intelligence is touching almost every aspect of our lives. It’s reasonable to expect AI influence will only increase in the future. One of many fields heavily influenced by AI is the military. Particularly in the development of Supersoldiers. The notion of super-soldiers enhanced with biotechnology and cybernetics was once only possible in the realm of science fiction. But it may not be too long before these concepts become a reality.

A new worldwide arms race is pitting countries against each other to be the first to successfully create real genetically modified super soldiers by using tools such as CRISPR. Understandably many of these human enhancement technologies raise health and safety questions and it is more likely these enhancements will first gain traction in countries that do not place as much weight on ethical concerns.

The Goodness of the Universe — John Smart

Posted by in categories: cryonics, life extension, neuroscience, robotics/AI

Outer Space, Inner Space, and the Future of Networks.
Synopsis: Does the History, Dynamics, and Structure of our Universe give any evidence that it is inherently “Good”? Does it appear to be statistically protective of adapted complexity and intelligence? Which aspects of the big history of our universe appear to be random? Which are predictable? What drives universal and societal accelerating change, and why have they both been so stable? What has developed progressively in our universe, as opposed to merely evolving randomly? Will humanity’s future be to venture to the stars (outer space) or will we increasingly escape our physical universe, into physical and virtual inner space (the transcension hypothesis)? In Earth’s big history, what can we say about what has survived and improved? Do we see any progressive improvement in humanity’s thoughts or actions? When is anthropogenic risk existential or developmental (growing pains)? In either case, how can we minimize such risk? What values do well-built networks have? What can we learn about the nature of our most adaptive complex networks, to improve our personal, team, organizational, societal, global, and universal futures? I’ll touch on each of these vital questions, which I’ve been researching and writing about since 1999, and discussing with a community of scholars at Evo-Devo Universe (join us!) since 2008.

For fun background reading, see John’s Goodness of the Universe post on Centauri Dreams, and “Evolutionary Development: A Universal Perspective”, 2019.
