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

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

The European Space Agency (ESA)and the EU, together with industrial and educational partners, are developing the first large-scale production methods to 3D-print complex 3D-printed parts made of metal that can withstand temperatures at 1000°C — fit for space and the most demanding applications on Earth.
3D printers are expected to revolutionize the way we live but until recently they could work with only plastic, which… read more

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

“By 2040 or so, astronomers will have scanned enough star systems to give themselves a great shot of discovering alien-produced electromagnetic signals,” said Seth Shostak, Senior Astronomer at the SETI Institute, Space.com reports.
Shostak spoke at the NASA Innovative Advanced Concepts (NIAC) symposium on Feb. 6 at Stanford University.
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.

The Ivanpah Solar Electric Generating System in California’s Mojave Desert produced its first output of energy when the first of three towers was synchronized last week to the power grid for the first time.
Power generated from Ivanpah will first go to Pacific Gas and Electric (PG&E), followed by Southern California Edison in the coming months.
Ivanpah is the largest solar thermal plant in the… read more

Unthinkable as it may be, humanity, every last person, could someday be wiped from the face of the Earth. We have learned to worry about asteroids and supervolcanoes, but the more-likely scenario, according to Nick Bostrom, a professor of philosophy at Oxford, is that we humans will destroy ourselves.
Most worrying to Bostrom is the subset of existential risks that arise from human technology, a subset that he expects… read more

Resveratrol — a natural antioxidant compound found in red grapes and other plants — counteracts many of the cardiovascular benefits of exercise in older men, including reduced blood pressure and cholesterol, according to research conducted at The University of Copenhagen.
Lasse Gliemann, a PhD student who worked on the study at The University of Copenhagen, explains how they conducted the research, and the results they found:
“We… read more

The key is timing and recall of that memory, said Jason Chan, an assistant professor of psychology at Iowa State.
“If you reactivate a memory by retrieving it, that memory becomes susceptible to changes again. And if at that time, you give people new contradictory… read more

Researchers at King’s College London, Harvard University and Massachusetts General Hospital have identified a key factor responsible for declining muscle repair during aging, and discovered how to halt the process in mice with a common drug.
The finding provides clues as to how muscles lose mass with age, which can result in weakness that affects mobility and may cause falls.
The study looked at stem… read more

Building a supercomputer on the moon would be a mammoth technical undertaking, but a University of Southern California graduate student thinks there’s a very good reason for doing it: help alleviate a coming deep-space network traffic jam that’s had NASA scientists worried for several years now.
