Video games. The last i heard AI had been up to playing and Mastering Atari 2600 games, and that was a few years ago. Figured it was only a matter of time til they started playing around with current gen stuff.

Hmmm.

Testimonials from prominent physics researchers from institutions such as Cambridge University, Princeton University, and the Max Planck Institute for Physics in Munich claim that quantum mechanics predicts some version of “life after death.”

They assert that a person may possess a body-soul duality that is an extension of the wave-particle duality of subatomic particles.

Neurons that fire together really do wire together, says a new study in Science, suggesting that the three-pound computer in our heads may be more malleable than we think.

In the latest issue of Science, neuroscientists at Columbia University demonstrate that a set of neurons trained to fire in unison could be reactivated as much as a day later if just one neuron in the network was stimulated. Though further research is needed, their findings suggest that groups of activated neurons may form the basic building blocks of learning and memory, as originally hypothesized by psychologist Donald Hebb in the 1940s.

“I always thought the brain was mostly hard-wired,” said the study’s senior author, Dr. Rafael Yuste, a neuroscience professor at Columbia University. “But then I saw the results and said ‘Holy moly, this whole thing is plastic.’ We’re dealing with a plastic computer that’s constantly learning and changing.”

Researchers have used CRISPR—a revolutionary new genetic engineering technique—to convert cells isolated from mouse connective tissue directly into neuronal cells.

In 2006, Shinya Yamanaka, a professor at the Institute for Frontier Medical Sciences at Kyoto University at the time, discovered how to revert adult connective tissue cells, called fibroblasts, back into immature stem cells that could differentiate into any cell type. These so-called induced pluripotent stem cells won Yamanaka the Nobel Prize in medicine just six years later for their promise in research and medicine.

Since then, researchers have discovered other ways to convert cells between different types. This is mostly done by introducing many extra copies of “master switch” genes that produce proteins that turn on entire genetic networks responsible for producing a particular cell type.

Mirror neurons allow individuals to, in essence, feel what others are experiencing. These neurons fire when an individual experiences something and when they observe the same or similar act happen to another.

Synesthesia, a neurological trait with more than 80 forms and growing numbers of people who recognize it in themselves, is mostly associated with famous creatives who have possessed it–from Pharrell Williams to David Hockney and from Mary J. Blige to Marilyn Monroe.

I know so many people who will benefit from this.

During the 2014 FIFA World Cup opening ceremony, a young Brazilian man, paralyzed from the chest down, delivered the opening kickoff. He used a brain-machine interface, allowing him to control the movements of a lower-limb robotic exoskeleton.

This unprecedented scientific demonstration was the work of the Walk Again Project (WAP), a nonprofit, international research consortium that includes Alan Rudolph, vice president for research at Colorado State University, who is also an adjunct faculty member at Duke University’s Center for Neuroengineering.

Controlling the minds of others from a distance has long been a favourite science fiction theme – but recent advances in genetics and neuroscience suggest that we might soon have that power for real. Just over a decade ago, the bioengineer Karl Deisseroth and his colleagues at Stanford University published their paper on the optical control of the brain – now known as optogenetics – in which the firing pattern of neurons is controlled by light. To create the system, they retrofitted neurons in mouse brains with genes for a biomolecule called channelrhodopsin, found in algae. Channelrhodopsin uses energy from light to open pathways so that charged ions can flow into cells. The charged ions can alter the electrical activity of neurons, influencing the animal’s behaviour along the way.

Soon researchers were using implants to guide light to channelrhodopsin in specific neurons in the brains of those mice, eliciting behaviour on demand. At the University of California the team of Anatol Kreitzer worked with Deisseroth to disrupt movement, mimicking Parkinson’s disease and even restoring normal movement in a Parkinsonian mouse. Deisseroth and his colleague Luis de Lecea later demonstrated that it was possible to wake up mice by activating a group of neurons in the brain that control arousal and sleep.

But optogenetics has been challenging. Since light does not easily penetrate dense fatty brain tissue, researchers must implant a fibre-optic cable to bring light into the brain. This limitation led to the development of another, less intrusive technique known as DREADD (designer receptors exclusively activated by designer drugs). In this case, a receptor normally activated by the neurotransmitter acetylcholine is modified to respond to a designer drug not normally found in the body. When the designer drug is delivered, neurons can be manipulated and behaviour changed over a number of hours. The major drawback here: the slow course of drug administration compared with the rapid changes in brain activity that occur during most tasks.

Eight completely paralysed people have regained function in their limbs following virtual reality training, in an accidental result that has astonished even the scientists involved.

Using a brain-machine interface, scientists showed that people with long-term severe paralysis could retrain the few remaining connections in their damaged spines, letting their brains talk to their extremities once more. This enabled them to feel sensation, move their limbs and improved their bladder and bowel control.

The results came about as a wholly unexpected side effect of training to help people use robotic exoskeletons, which let them walk upright.

Would you want to alter your future children’s genes to make them smarter, stronger or better-looking? As the state of the science brings prospects like these closer to reality, an international debate has been raging over the ethics of enhancing human capacities with biotechnologies such as so-called smart pills, brain implants and gene editing. This discussion has only intensified in the past year with the advent of the CRISPR-cas9 gene editing tool, which raises the specter of tinkering with our DNA to improve traits like intelligence, athleticism and even moral reasoning.
