Spin valves are essential building blocks in the magnetic sensors of read heads in hard disk drives. They consist of two magnetic layers separated by a non-magnetic layer and act as valves for electrons depending on the relative alignment of the magnetization (spin) in the magnetic layers. With the continuous push to boost the storage density of disk drives, it has become increasingly important to shield each individual sensor from the magnetic flux of adjacent bits

When people email photos, they sometimes compress the images, removing redundant information and thus reducing the file size. Compression is generally thought of as something to do to data after it has been collected, but mathematicians have recently figured out a way to use similar principles to drastically reduce the amount of data that needs to be gathered in the first place

Multilayer Laue lenses (MLLs) developed at the U.S. Department of Energy Office of Science’s Advanced Photon Source (APS) focus high-energy x-rays so tightly they can detect objects as small as 16 nanometers in size, and are in principle capable of focusing well below 10 nanometers

Dear EarthTalk : Recently the U.N. voted to declare access to safe and clean water a “human right ” . Isn’t that a no-brainer
