The purpose is to help scientists understand how the complex activity of the brain gives rise to the complex behavior exhibited by animals, including humans.

The Heisenberg uncertainty principle is one of the cornerstones of quantum mechanics: it’s impossible to measure anything without disturbing it.
For instance, any attempt to measure a particle’s position must change its momentum.
But never mind all that. It’s wrong, University of Toronto physicists say they have just proven.
(This has important implications for quantum information and especially quantum cryptography, where it is fundamental to the security of certain protocols.)… read more
Neuroscientists find cortical columns in brain not uniform, challenging large-scale simulation models
October 25, 2013
Despite a long-held scientific belief that cortex is built up by repeatedly occurring elementary units called cortical columns, a new study by neuroscientists has found that the structure of the brain’s cortical columns can largely deviate within individual animals, and even within a specific cortical area.
The study also found that these structural differences are not arbitrary, but reflect organizational and functional properties of the… read more

Certain black holes can have a complex internal structure that could allow photons, particles, and perhaps even planets to orbit the central singularity without ever getting sucked all the way in, Technology Review Physics arXiv Blog reports.
“Advanced civilizations may live safely inside the supermassive black holes in the galactic nuclei without being visible from the outside,” says Vyacheslav Dokuchaev, Institute for Nuclear Research of the Russian… read more
Quantum computing should be applied to robots, automatons, and other agents that use AI to make them more creative and to learn and respond faster than conventional robots, researchers from the Complutense University of Madrid (UCM) and the University of Innsbruck (Austria) recommend.

New data suggests the exoplanet Gliese 581g is the best candidate so far of a potential habitable exoplanet. The nearby star Gliese 581 — located about 20 light years away from Earth in the constellation Libra — has four planets; the outermost planet, Gliese 581d, was already suspected habitable.
This will be the first evidence for any two potential habitable exoplanets that are orbiting the same star.
Based on… read more

Schmitt suggests the new agency be called the National Space Exploration Administration.
The new deep-space agency should “stay young, and develop a management structure that is not so hierarchical — that is actually a… read more

Making things at home on a 3D printer uses less energy — and therefore releases less carbon dioxide — than producing it in a factory and shipping it to a warehouse.
The team conducted life-cycle impact analyses on three products:… read more
Researchers* from Malaysia and the UK have used a new multi-material 3D printer to create realistic, low-cost model of the skull for use by students in practicing neurosurgical techniques.
The model uses a variety of materials that simulate the various consistencies and densities of human tissues encountered during neurosurgery.
Neurosurgery is a difficult discipline to master. Trainees may spend as many as 10 years after graduation from medical… read more
Elon Musk has been hinting at an idea he calls the Hyperloop — a ground-based transportation technology that would get people from Los Angeles to San Francisco in under half an hour, for less than 1/10 the cost of California’s $69 billion plan.

It depends. Older and younger people have varying preferences about what they would want a personal robot to look like, and they change their minds based on what the robot is supposed to do, a new study from the Georgia Institute of Technology has found.
Participants were shown a series of photos portraying either robotic, human, or mixed human-robot faces and were asked to select… read more

Older adults who drank coffee — caffeinated or decaffeinated — had a lower risk of death overall than others who did not drink coffee, according a study by researchers from the National Cancer Institute (NCI), part of the National Institutes of Health, and AARP.
Coffee drinkers were less likely to die from heart disease, respiratory disease, stroke, injuries and accidents, diabetes, and infections, although the association was… read more

When a person learns something, a lasting long-term memory is created with the aid of a process of consolidation, which is based on the formation of proteins. When we remember something, the memory becomes unstable for a while and is then restabilized by another consolidation process.
In other words,… read more
