Of all the personal computers to be unwrapped during the holiday season, more than 80 percent will be used to go online and search the Web’s more than 92 million gigabytes of data (comparable to a 2 billion-volume encyclopedia). Getting online is the easy part, finding a useful Web page is a bit harder-keeping track of a useful Web page is another issue altogether.
People have devised many tricks-such as sending e- mails to themselves or jotting on sticky notes-for keeping track of Web pages, but William Jones and Harry Bruce at the University of Washington’s Information School and Susan Dumais of Microsoft Research have found that often people don’t use any of them when it comes time to revisit a Web page. Instead, they rely on their ability to find the Web page all over again.
"People are terribly challenged by this, and the problem is becoming worse," Bruce said. "People should have fast, easy access to the right information, at the right time, in the right place, in the right quantity to complete the task at hand."

New research group at the University of Jena combines theory and experiment to demonstrate for the first time certain physical processes in a quantum vacuum
For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles...
Physicists in the EPic Lab at University of Sussex make crucial development in global race to develop a portable atomic clock
Scientists in the Emergent Photonics Lab (EPic Lab) at the University of Sussex have made a breakthrough to a crucial element of an atomic clock - devices...

Combining an atomically thin graphene and a boron nitride layer at a slightly rotated angle changes their electrical properties. Physicists at the University of Basel have now shown for the first time the combination with a third layer can result in new material properties also in a three-layer sandwich of carbon and boron nitride. This significantly increases the number of potential synthetic materials, report the researchers in the scientific journal Nano Letters.
Last year, researchers in the US caused a big stir when they showed that rotating two stacked graphene layers by a “magical” angle of 1.1 degrees turns...
