wafer holds many individual microrobots. Each robot consists of a body (about 100 micrometers long) and an arm that it uses to turn. Several of these robots can be controlled at once. Credit: Igor Paprotny Researchers at the University of California, Berkeley and Duke University have shown how to use a single electrical signal to …
Schematics of a typical LSCO-LCO heterostructure used to fabricate EDLT devices. For clarity, the polymer electrolyte (or the ionic liquid) is not shown; we just show the anions adsorbed to the film surface and the cations attracted to the negatively charged Pt gate electrode. Like atomic-level bricklayers, researchers from the U.S. Department of Energy’s (DOE) …
An atomic-scale depiction of the SketchSET shows three wires (green bars) converging on the central island (center green area), which can house up to two electrons. Electrons tunnel from one wire to another through the island. Conditions on the third wire can result in distinct conductive properties. A team from Pitt, UW-Madison, and HP Labs …
ASU researchers have expanded on the capabilities of DNA origami to construct arbitrary two- and three-dimensional shapes, mimicking those often found in nature. The research is featured in the April 15 edition of the journal Science. Photo courtesy of Science. Figure 1 a and b display schematics for 2D nanoforms with accompanying AFM images of …
1. CIBC’s Andrew Potter estimates that Canada’s oil sands production will jump from 1.5 million barrels a day in 2010 to five million barrels by 2020. This is being caused by high oil prices in combination with low natural gas prices. “In situ projects are highly dependent on the price of natural gas,” says Marc …
The Wall Street journal coverage of the Paul Ryan budget. Budget enforcement: This budget recognizes that it is not enough to change how much government spends. We must also change how government spends. It proposes budget-process reforms—including real, enforceable caps on spending—to make sure government spends and taxes only as much as it needs to …
More stringent emissions standards for motor vehicles would affect regions differently. Climate impacts are shown in terms of radiative forcing (top row), a measure of the change in the Earth’s energy balance. Positive forcing accelerates global warming, whereas negative forcing slows it. Health benefits are shown as avoided premature deaths (2nd row). Agricultural benefits are …
1. Rod Adams at Atomic Insights provides a summary of the Fukushima Nuclear Accident from Murray Miles. Murray Miles happens to know something about these Japanese plants. Oyster Creek on Barnegat Bay in New Jersey went on line one year before the number one Fukushima Daiichi plant and has the same design. He worked there …
There is on the order of 7000 deaths per year from terrorism. state department stats on terrorism Most of it is terrorism within Afghanistan and Iraq. Global terrorism has far lower numbers of about 300-700 per year (other than in 2001). There were about 200,000 murders in the world (2000). 2-3% are likely arson, which …
Procedures that the Fukushima nuclear plant workers would be following to deal with high R=radiation dose rates (like the high readings of 40 REM/hr) – move to an area with a lower dose rate. Radiation dose rates obey physical laws – if you double your distance from the source, you reduce the rate by a …
We will have the means shepard many small asteroid fairly soon using solar sails, solar electric sails and highly efficient propulsion mated to light robotic spacecraft. Then we could inflate the an actual living space inside and be protected from radiation and micrometeorites. I think that moving asteroids of various sizes into positions to act …
