Researchers at Yale University have succeeded in measuring an electric current flowing through a single organic molecule sandwiched between metal electrodes. The feat could pave the way for a new generation of transistors so small that a beaker full would contain more transistors than exist in the world today, or so reports team leader and Yale electrical engineer Mark A. Reed. To capture the historic measurement of current across a single organic molecule, the researchers made a mechanically controllable break junction by gluing a notched gold wire to a flexible substrate. They then fractured the wire to make an adjustable gap. Next, they sandwiched a single molecule of benzene flanked by two sticky sulfur atoms between the two gold electrodes. What's the potential results? "Thousands of silicon transistors can be produced now for less than a penny," Reed explains, "but the dramatic decrease in cost per transistor that we've enjoyed over the last two decades will start to slow down soon." The answer, Reed believes, is to find materials that will assemble themselves into quantum components. E-mail firstname.lastname@example.org.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
