“Many engineers, including me, think that some time around 2050, we will be able to make very high quality links between the brains and machines. … If your mind is so well connected, you could inhabit a new body, without having to vacate your existing one,” suggests futurologist Ian Pearson.

“Using a detachable brain is one option, or not to put a brain in at all, using empty immobile husks that… read more

What would it be like if you could transfer your personal data, your consciousness, to a robot or a machine?”

That’s what almost every major technology organization seems to be asking, says Huffington Post blogger  Lucas Kavner.

Examples:

  • Terasem’s LifeNaut project allows you to create a mindfile for yourself, or anybody else close to you, using photos and online data and other “digital reflections” you

Setting up a lunar base could be made much simpler by using a 3D printer to build it from local materials.

Renowned architects Foster + Partners have joined with ESA to test the feasibility of 3D printing using simulated lunar soil (regolith).

The architects devised a weight-bearing “catenary” dome design with a cellular structured wall to shield against micrometeoroids and space radiation, incorporating a… read more

NASA aims for human rendezvous at Mars in 2033

It would be the most precious cargo since the Apollo astronauts returned Moon rocks to Earth.

In 2033, humans would arrive in Mars orbit to pick up and return to Earth a small collection of Mars rocks that would have been previously collected and put into orbit.

An internal NASA study group, tasked with replanning the agency’s beleaguered Mars program, revealed onread more

Scientists achieve fuel gain exceeding unity in confined fusion implosion

The milestone of achieving fuel gains greater than 1 has been reached at the Lawrence Livermore National Laboratory (LLNL) National Ignition Facility (NIF) — for the first time ever at any facility.

Ignition — the process of releasing fusion energy equal to or greater than the amount of energy used to confine the fuel — has long been considered the “holy grail” of inertial confinement… read more

More evidence that you’re a mindless robot with no free will

How we may confabulate reality and rationalize irrational behavior

The results of two Yale University psychology experiments suggest that what we believe to be a conscious choice may actually be constructed, or confabulated, unconsciously after we act — to rationalize our decisions. A trick of the mind.

“Our minds may be rewriting history,” said Adam Bear, a Ph.D. student in the Department of Psychology and lead author of a paper published April 28… read more

A top secret National Security Agency program allows analysts to search with no prior authorization through vast databases containing emails, online chats and the browsing histories of millions of individuals — its “widest-reaching” system for developing intelligence from the Internet — according to documents provided by whistleblower Edward Snowden, Guardian columnist Glenn Greenwald reported Wednesday.

The latest revelations come as senior intelligence officials… read more

Is a scientific definition of consciousness possible?

Consciousness arises from the mode in which billions of neurons communicate with one another, psychologists suggest
October 20, 2013

Parcellation of brain data into 194 cortical, subcortical and cerebellar ROIs.

UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness.

Their research, published in the online open-access journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness, the researchers say.

“In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving… read more
