Uncovering the Veil (Nebula)
NASA – The Veil Nebula, left behind by the explosion of a massive star thousands of years ago, is one of the largest and most spectacular supernova remnants in the sky.

Obama’s gamble: Asking for more time to fix economy

By Andy Sullivan and Caren Bohan – So far, President Barack Obama has not been able to convince most Americans that they are better off than they were four years ago. His next step may be to try to convince them that they would be worse off under his Republican rival, Mitt Romney.

In focus groups, voters told the three strategists that they have seen little evidence of an economic turnaround as they struggle to pay for basic necessities.

“You need to see it in the grocery stores. You need to see it as the gas stations. You need, the consumer needs, to see the result and there’s no result of that yet,” an unidentified woman in Columbus, Ohio, told the strategists. more> http://tinyurl.com/c2bmbd7

Europe Unprepared as Euro Crisis Deepens

By Stefan Kaiser – Greek voters go to the polls on Sunday in an election that many believe could determine whether the country remains in the euro zone or is forced out. Potentially more ominously, numbers released on Monday indicate that the Italian economy is in disastrous shape, having shrunk in the first quarter faster than it has in three years.

Even if the effort to stabilize Spain’s banks is successful, the country and the euro zone are still not out of the woods. The crisis, after all, has long since become much more than a banking crisis, even in Spain. more> http://tinyurl.com/6vem53t

Future Directions for Magnetic Sensors

NIST – Bringing new or improved magnetic sensors to market requires modeling for rapid assessment of the effect of new designs or improved materials properties. To this end, we are investigating the fundamental properties of a new class of magnetic sensors that is rapidly displacing ones based on older technology. The new sensors are based on Magnetic Tunnel Junctions (MTJs) which use the Tunneling Magnetoresistance Effect (TMR). To optimize MTJs, NIST has purchased an instrument that diagnoses the TMR properties early in the fabrication process to maximize efficient use of time.

These instruments are not widely available, and NIST is beginning to serve as a clearing house for MTJ testing by offering diagnosis of MTJs of outside groups. The resulting collaborations with small companies, universities, and national labs are allowing NIST to lead the world in non-proprietary MTJ research. more> http://tinyurl.com/ccnt9px

If the Gold Standard Scares You, How About a Parallel Currency Option?

By Nathan Lewis – Most countries in the world have some sort of currency link, formal or informal, with major international currencies, to maintain stable trade conditions. This link might be a fixed system, like Hong Kong’s currency board, or it might be a more casual arrangement, such as Russia’s unofficial policy of maintaining the ruble in a stable band compared to the dollar or euro.

Several U.S. states, beginning with Utah, have already begun to lay the legal groundwork for gold-linked secondary currencies in the U.S. However, I think there is a great opportunity for something we haven’t seen before: a state-sponsored major international gold-linked parallel currency. more> http://tinyurl.com/cf2o7lt
