“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

Can human-machine superintelligence solve the world’s most dire problems?

January 5, 2016

New human-computation technologies: In creating problem-solving ecosystems, researchers are beginning to explore how to combine the cognitive processing of many human contributors with machine-based computing to build faithful models of the complex, interdependent systems that underlie the world’s most challenging problems.

“Human computation” — combining human and computer intelligence in crowd-powered systems — might be what we need to solve the “wicked” problems of the world, such as climate change and geopolitical conflict, say researchers from the Human Computation Institute (HCI) and Cornell University.

In an article published in the journal Science, the authors present a new vision of human computation… read more

NSA hacks Yahoo, Google data-center cables worldwide

October 30, 2013

NSA-Google

The NSA has secretly broken into fiber-optic cables that connect Yahoo and Google data centers around the world — positioning itself to collect at will from hundreds of millions of user accounts, many of them belonging to Americans, according to documents obtained from former NSA contractor Edward Snowden and interviews with knowledgeable officials, the Washington Post reported today.

According to a top-secret accounting dated… read more

Scientists achieve fuel gain exceeding unity in confined fusion implosion

February 13, 2014

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

Mars One design not feasible, MIT researchers find

MIT researchers have developed a detailed settlement-analysis tool to assess the feasibility of the Mars One plans to establish the first human colony on Mars by 2025,  finding that new technologies will be needed to keep humans alive on Mars.

Mars One —  considered by some to be essentially a Dutch-made reality TV show — claims that the entire mission can be built upon technologies that already… read more

XKeyscore: NSA tool collects ‘nearly everything a user does on the Internet’

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
