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

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

For electric vehicles and plug-in hybrids to compete with gas-powered cars, battery prices need to drop by between 50 and 80 percent, according to recent estimates by the U.S. Department of Energy.

Improvements to the lithium-ion batteries that power the current generation of electric vehicles may be enough, MIT Technology Review reports.

The first firm details of the 15 February asteroid impact in Russia, the largest in more than a century, are becoming clear. ESA is carefully assessing the information as crucial input for developing the Agency’s asteroid-hunting effort.

At 03:20 GMT on 15 February, a natural object entered the atmosphere and disintegrated in the skies over Chelyabinsk, Russia.

Extensive video records indicate a northeast to… read 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

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

How many planets are in our galaxy?

Billions and billions of them at least. That’s the conclusion of a new study by astronomers at the California Institute of Technology, which provides yet more evidence that planetary systems are the cosmic norm.

The team made their estimate while analyzing planets orbiting a star called Kepler-32 — planets that are representative, they say, of the vast majority… read more
