MRAM is here. The American company Freescale has unveiled a magnetoresistive random access memory chip (MRAM) that it says is a vast improvement over current chips. If early tests are any indication, this just might be the case. First and foremost, an MRAM chip holds information after the power to a device has been turned […]
One of the best ways you can go green is to ditch your reliance on the printed word. You can go with paperless billing for your cell phone and other expenses, for example. Another way you can minimize your reliance on chopped-down trees is to read all of your content through an e-reader rather than […]
re the density of a single cell. The researchers designed a tiny microfluidic chip that can measure the mass and density of single cells. The device weighs a cell using a suspended micro-channel resonator, which is the size of a human hair. The resonator vibrates at a certain frequency. When a cell passes through the resonator, the frequency changes by an amount proportional to the weight of the cell.
