Enhancing the Magnetism: Berkeley Researchers Find Enhanced and Controllable Magnetization in Unique Bismuth Ferrite Films

“The nation that controls magnetism will control the universe,” famed fictional detective Dick Tracy predicted back in 1935. Probably an overstatement, but there’s little doubt the nation that leads the development of advanced magnetoelectronic or “spintronic” devices is going to have a serious leg-up on its Information Age competition. A smaller, faster and cheaper way to store and transfer information is the spintronic grand prize and a key to winning this prize is understanding and controlling a multiferroic property known as “spontaneous magnetization.”

Now, researchers with the U.S. Department of Energy (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) have been able to enhance spontaneous magnetization in special versions of the popular multiferroic material bismuth ferrite. What’s more, they can turn this magnetization “on/off” through the application of an external electric field, a critical ability for the advancement of spintronic technology. (more…)

Levels of radioactive iodine in seawater just offshore of the embattled Fukushima Daiichi nuclear plant spiked to more than 1,250 times higher than normal, Japan’s nuclear and industrial safety agency said Saturday.

Samples taken Friday morning from a monitoring station 330 meters off the coast were significantly higher than results from the previous morning, when the level was 104 times above normal, according to CNN International. (more…)

MU Researcher Works to Save One of the World’s Most Endangered Birds

COLUMBIA, Mo. — The Tuamotu Kingfisher is a multicolored, tropical bird with bright blue feathers, a dusty orange head, and a bright green back. The entire population of these birds – less than 125 – lives on one tiny island in the south Pacific, and without serious intervention, they will no longer exist. One University of Missouri researcher is trying to stop the birds’ extinction by working with farmers and residents on the island inhabited by the kingfishers.

“If we lose these birds, we lose 50,000 years of uniqueness and evolution,” said Dylan Kesler, assistant professor in fisheries and wildlife at the University of Missouri’s School of Natural Resources in the College of Agriculture, Food and Natural Resources. “Because it has lived in isolation for a very long time, it’s unlike any other bird. There is no other bird like this on the planet.” (more…)

On the Sizeable Wings of Albatrosses

An oceanographer may be offering the best explanation yet of one of the great mysteries of flight—how albatrosses fly such vast distances, even around the world, almost without flapping their wings. The answer, says Philip L. Richardson of the Woods Hole Oceanographic Institution (WHOI), lies in a concept called dynamic soaring, in which the large bird utilizes the power of above-ocean wind shear while tacking like an airborne sailboat.

*Leading analyst firm points to opportunities for Microsoft partners both in cloud computing and with current Microsoft products.*

REDMOND, Wash. — March 24, 2011 — Today, global research firm IDC issued a new white paper which estimates that members of the worldwide Microsoft ecosystem generated local revenues for themselves of $580 billion in 2010, up from $537 billion in 2009 and $475 billion in 2007. This demonstrates strong revenue growth when total worldwide IT spending increased less than half a percent, and validates the substantial opportunities and benefits available through the Microsoft Partner Network, the program that equips Microsoft partners with training, resources and support they need to successfully compete in today’s marketplace while allowing customers to easily identify the right partner for their technology needs.

Through the Microsoft Partner Network https://partner.microsoft.com, partners can extend their market reach for greater opportunities and profitability while delivering innovative solutions to help customers achieve their business goals. The IDC study estimates that for every dollar of revenue made by Microsoft Corp. in 2009, local members of the Microsoft ecosystem generated revenues for themselves of $8.70. In an additional study on Microsoft Core Infrastructure Optimization, IDC found that partners that invested in more difficult or a greater number of Microsoft competencies enjoyed 68 percent larger deals and 28 percent more revenue per employee, compared with partners that invested less.
