BMI implant leveraging AI.

You probably clicked on this article because the idea of using brain implants to allow artificial intelligence (AI) to read your brain sounds futuristic and fascinating. It is fascinating, but it’s not as futuristic as you might think. Before we start talking about brain implants and how to augment the human brain using AI, we need to put some context around human intelligence and why we might want to tinker with it.

We floated the idea before that gene editing techniques could allow us to promote genetic intelligence by performing gene editing at the germline. That’s one approach. As controversial as it might be, some solid scientific research shows that genetics does play a role in intelligence. For those of us who are already alive and well, this sort of intelligence enhancement won’t work. This is where we might look towards augmented intelligence. This sort of augmentation of the brain will firstly be preventative in that it will look to assist those who have age associated brain disorders as an example. In order for augmented intelligence to be feasible though, we need a read/write interface to the human brain. One company called Kernel might be looking to address this with a technology that takes a page out of science fiction.

Summary: Researchers have discovered a link between nerve clusters in the brain and the amount of force generated by a physical action.

Researchers have found a link between the activity in nerve clusters in the brain and the amount of force generated in a physical action, opening the way for the development of better devices to assist paralysed patients.

There has been a lot of digital ink spilled over the recent paper on the reactionless thrust device known as the EMDrive. While it’s clear that a working EM Drive would violate well established scientific theories, what isn’t clear is how such a violation might be resolved. Some have argued that the thrust could be an effect of Unruh radiation, but the authors of the new paper argue instead for a variation on quantum theory known as the pilot wave model.

One of the central features of quantum theory is its counter-intuitive behavior often called particle-wave duality. Depending on the situation, quantum objects can have characteristics of a wave or characteristics of a particle. This is due to the inherent limitations on what we can know about quanta. In the usual Copenhagen interpretation of quantum theory, an object is defined by its wavefunction. The wavefunction describes the probability of finding a particle in a particular location. The object is in an indefinite, probabilistic state described by the wavefunction until it is observed. When it is observed, the wavefunction collapses, and the object becomes a definite particle with a definite location.

While the Copenhagen interpretation is not the best way to visualize quantum objects it captures the basic idea that quanta are local, but can be in an indefinite state. This differs from the classical objects (such as Newtonian theory) where things are both local and definite. We can know, for example, where a baseball is and what it is doing at any given time.

Time travel could be possible, says a group of physicists who’ve come up with a new interpretation of our universe, says the Sun U.K.

Professor Howard Wiseman and Dr. Michael Hall from Griffith University’s Centre for Quantum Dynamics, and Dr. Dirk-Andre Deckert from the University of California, say there are many universes, including identical ones to ours, that “influence one another through quantum mechanics.” The theory is called the “Many-Worlds Interpretation.”

What this means is that travelling through time within our universe is conceivable, says the Sun.
