"In the 1948 paper that created the field of information theory, MIT grad (and future professor) Claude Shannon threw down the gauntlet to future generations of researchers. In those predigital days, communications channels - such as phone lines or radio bands - were particularly susceptible to the electrical or electromagnetic disruptions known as "noise.""

"It's the early 1980s, and you're an equipment manufacturer for the fledgling personal-computer market. For years, modems that send data over the telephone lines have been stuck at a maximum rate of 9.6 kilobits per second: if you try to increase the rate, an intolerable number of errors creeps into the data."

"A lawyer is trying to convince a jury that his client really is crazy. It's usually a tough argument to sell in a court of law. But what if the lawyer has a picture of his client's brain that shows there's something biologically wrong with it? Can that evidence help persuade a jury? Should it even be allowed as evidence?"

"The water content of leaves, their thickness, their density and other properties can now be determined without even having to touch them. A team of researchers from the CSIC Institute of Acoustics and the Agri-Food Research and Technology Centre (CITA) of Aragón has just presented an innovative technique that enables plant leaves to be studied using ultrasound in a quick, simple and non-invasive fashion."

"Basically, any computing device (or switch, or router) that is based on light requires a nonlinear interaction between different light beams, but light doesn't like to do nonlinear stuff. With current technology, you can get efficient nonlinear optical interactions, but the hardware is kind of bulky or very delicate. Not the sort of thing you want to put in a billion devices. What my friends in Barcelona have demonstrated is that it's possible to create a relatively efficient optical nonlinear interaction in a nano-structured metallic surface. "
