Data Storage of Tomorrow: Ferroelectricity On the Nanoscale

Promising news for those who relish the prospects of a one-inch chip storing multiple terabytes of data, some clarity has been brought to the here-to-fore confusing physics of ferroelectric nanomaterials. A multi-institutional team of researchers, led by scientists at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) has provided the first atomic-scale insights into the ferroelectric properties of nanocrystals. This information will be critical for development of the next generation of nonvolatile data storage devices.

North Carolina agencies investigating Duke Energy CEO shuffle

HOUSTON (Reuters) - North Carolina officials late Friday launched two investigations into the surprising move by Duke Energy Corp directors to replace former Progress Energy Chief Executive Bill Johnson with Duke CEO Jim Rogers, just a day after a deal to create the largest U.S. utility company was finalized.

The North Carolina Utilities Commission, which approved Duke's $18 billion buyout of Progress late last week, ordered Rogers to appear at a hearing Tuesday to answer questions on the timing of the decision to replace Johnson, the commission said in a two-page order.

Mystery Wave in Milky Way Galaxy Suggests Recent Crash

"We have found evidence that our Milky Way had an encounter with a small galaxy or massive dark matter structure perhaps as recently as 100 million years ago," said Larry Widrow, a professor at Queen’s University in Canada. "We clearly observe unexpected differences in the Milky Way’s stellar distribution above and below the Galaxy's midplane that have the appearance of a vertical wave — something that nobody has seen before."

Steve Lambert, Capitalism Works For Me! True/False, 2011 aluminum and electronics

As an artist/citizen Steve Lambert is interested in dialogue: how discourse exists in the public sphere, and how language can and cannot function in that capacity. To that end, Lambert co-organizes workshops for artists and activists at the Center for Artistic Activism, gives lectures and performances about the convergence of cultural production and political agency, and founded the art group Anti-Advertising Agency, that examines advertising’s effect in public space. As part of his investigation into advertising, Lambert makes signs that take direct aim at marketing language.

 

New chip captures power from multiple sources: light, heat and vibrations

Researchers at MIT have taken a significant step toward battery-free monitoring systems — which could ultimately be used in biomedical devices, environmental sensors in remote locations and gauges in hard-to-reach spots, among other applications.

Previous work from the lab of MIT professor Anantha Chandrakasan has focused on the development of computer and wireless-communication chips that can operate at extremely low  levels, and on a variety of devices that can harness power from natural light, heat and vibrations in the environment. The latest development, carried out with doctoral student Saurav Bandyopadhyay, is a chip that could harness all three of these ambient power sources at once, optimizing power delivery.
