Is Quantum Space-Time a Scale-Free Network Like Facebook?

Posted by in categories: neuroscience, quantum physics, space

Researchers from Queen Mary University of London and Karlsruhe Institute of Technology have developed a model that applies ideas from the theory of complex networks, such as the brain or the Internet, to the fundamental quantum geometry of space-time.

The research is published in Scientific Reports with the title “Complex Quantum Network Manifolds in Dimension d > 2 are Scale-Free.” The research paper is freely available online.

“We hope that by applying our understanding of complex networks to one of the fundamental questions in physics we might be able to help explain how discrete quantum spaces emerge,” said author Ginestra Bianconi.

The Imminence of Transhuman Technologies

Posted by in categories: bioengineering, ethics, existential risks, genetics, health, innovation, neuroscience

Progress always seems to ride a slippery slope. Innovations generally bring a plethora of potential benefits and just as many dangers, the obvious and the hidden. Technologies that tamper with our biological constructs is well underway in the neuro- and biotech industries. Historically, innovations in medicine have usually been beneficial on the aggregate.

But these new breakthroughs go beyond preventing and healing pre-existing causes. Transhuman technologies hold the promise of enhancing who we are as individuals and potentially as an entire species, and the decisions surrounding these technologies are far from simple. Dr. Nayef Al-Rodhan, a philosopher, neuroscientist, and director of the Geneva Center for Security Policy, believes we should be acting now to prepare for the inevitable and the unpredictable ramifications.

Framing Human Motivation

Considering our mixed track record as a species in rolling out groundbreaking innovations, discussing and finding potential solutions to many of the hidden dangers, and obvious ones, seems more than reasonable. One of the more puzzling questions is, where do we begin to have a pragmatic conversation on the ethics of these technologies?

There are plenty of theories about what drive human decisions, not least because human morality is infinitely complex and our minds crave frames through which to make sense of chaos. Dr. Al-Rodhan has his own conception of what drives human motivations. He makes meaning using the lens of “5 P’s” – Power, Pride, Profit, Pleasure, and Permanence – which he posits drive human motivations. “This is my view, the foundation of my outlook…this perceived emotion of self interest drives our moral compass.”

Curing Alzheimer’s

Posted by in categories: biotech/medical, genetics, health, life extension, mobile phones, neuroscience, space

Dr Michael Fossel is a PhD and MD heading up telomerase research and therapy and has kindly written a blog article for Bioviva detailing the work both they and his company Telocyte are doing to fight back against Alzheimer’s.


How Alzheimer’s Can Be Prevented and Cured…

Michael Fossel, MD, PhD

As I said in my medical textbook on aging, “If age is a thief, then the greatest treasure we lose is ourselves.” We fear Alzheimer’s not simply because it takes away our health, but because it steals our souls.

You’re not irrational, you’re just quantum probabilistic: Researchers explain human decision-making with physics theory

Posted by in categories: neuroscience, quantum physics

The next time someone accuses you of making an irrational decision, just explain that you’re obeying the laws of quantum physics.

A new trend taking shape in not only uses to explain humans’ (sometimes) paradoxical thinking, but may also help researchers resolve certain contradictions among the results of previous psychological studies.

According to Zheng Joyce Wang and others who try to model our decision-making processes mathematically, the equations and axioms that most closely match human behavior may be ones that are rooted in quantum physics.

Scientists Hope To Resurrect A Dead Girl Who Wanted To Live Inside A Computer

Posted by in categories: computing, life extension, neuroscience

Kim Suozzi died at age 23 from glioblastoma — a deadly brain tumour.

When she died in 2013, she made sure her fight for survival, albeit an unusual one, would not be forgotten.

She wanted to live forever through a computer and chose to have her brain frozen in the hopes that it may one day be resurrected and transformed into digital code.

Paralyzed Man Successfully Given Prosthetic Hand That Can ‘Feel’

Posted by in categories: biotech/medical, cyborgs, electronics, neuroscience

A 28 year old man who has been paralysed has been given a new sense of touch following a new breakthrough that saw electrodes places directly into the man’s brain.

The research and clinical trial has been carried out by DARPA, the US Military’s research agency. Essentially, the man (who has not been named) is now able to control his new hand and feel people touching it because of two sets of electrodes: one array on the motor cortex, the part of the brain which directs body movement, and one on the sensory cortex, which is the part of the brain which feels touch.

Changing behavior through synaptic engineering

Posted by in categories: biotech/medical, engineering, neuroscience

Researchers at the University of Massachusetts Medical School are the first to show that it’s possible to reverse the behavior of an animal by flipping a switch in neuronal communication. The research, published in PLOS Biology, provides a new approach for studying the neural circuits that govern behavior and has important implications for how scientists think about neural connectomes.

New technologies have fueled the quest to map all the neural connections in the brain to understand how these networks processes information and control behavior. The human brain consists of 1011 neurons that make 1015 connections. The total length of neuronal processes in the human brain is approximately 4 million miles long, similar in length to the total number of roads in the U.S. Along these networks neurons communicate with each other through excitatory and inhibitory synapses that turn neurons on or off.

The neuronal roadmap, or connectome, however, doesn’t include information about the activity of neurons or the signals they transmit. How stable are these neural circuits in the brain? Does their wiring constrain the flow of information or the behaviors they control? The complexity of the human brain makes it almost impossible to address these questions.

This mind-controlled prosthetic robot arm lets you actually feel what it touches

Posted by in categories: biotech/medical, cyborgs, electronics, neuroscience, robotics/AI

The US government said today (Sept. 11) that it’s successfully made a Luke Skywalker-like prosthetic arm that allows the wearer to actually feel things.

At a conference in July, the US Defense Advanced Research Projects Agency (DARPA) presented the achievements it’d had to date in building a robot arm that can be controlled by a human brain. A little over two months later, the agency has announced at another conference that it’s managed to update the technology to give the wearer the feeling of actually being able to sense things with the arm.
