ananyo writes “Transistors, the simple switches at the heart of all modern electronics, generally use a tiny voltage to toggle between ‘on’ and ‘off.’ The voltage approach is highly reliable and easy to miniaturize, but has its disadvantages. First, keeping the voltage on requires power, which drives up the energy consumption of the microchip. Second, transistors must be hard-wired into the chips and can’t be reconfigured, which means computers need dedicated circuitry for all their functions. Now, researchers have made a type of transistor that can be switched with magnetism. The device could cut the power consumption of computers, cell phones and other electronics — and allow chips themselves to be ‘reprogrammed” (abstract).” Read more of this story at Slashdot.

Magnetic Transistor Could Cut Power Consumption and Make Chips Reprogrammable
An anonymous reader writes “‘Right now, there are brilliant students from all over the world sitting in classrooms at our top universities,’ President Obama explained to the nation Tuesday in his pitch for immigration reform. ‘They are earning degrees in the fields of the future, like engineering and computer science…We are giving them the skills to figure that out, but then we are going to turn around and tell them to start the business and create those jobs in China, or India, or Mexico, or someplace else. That is not how you grow new industries in America. That is how you give new industries to our competitors. That is why we need comprehensive immigration reform.” If the President truly fears that international students will use skills learned at U.S. colleges and universities to the detriment of the United States if they return home (isn’t a rising tide supposed to lift all boats?) — an argument NYC Mayor Bloomberg advanced in 2011 (‘we are investing millions of dollars [actually billions] to educate these students at our leading universities, and then giving the economic dividends back to our competitors – for free’) — then wouldn’t another option be not providing them with the skills in the first place?” Read more of this story at Slashdot.
