Graphene at 300 Gigahertz

UCLA scientists and engineers say they’ve made the fastest graphene-based field-effect transistor ever. Their device tops out at 300 gigahertz, about a threefold improvement over the previous record holder. Graphene transistors are now on track to reach terahertz speeds.

Podcast: Intel Puts Security Front and Center

Whether it’s in wireless tire-pressure car sensors, U.S. military computers, or the 2008 Spanair plane that crashed and killed 154 passengers, malicious software seems ever more dangerous. Embedded systems get infected, and in the brave new world of smartphones and iPads, the problem might get worse before it gets better. Host Steven Cherry talks with technology consultant Charles King about the strange logic of Intel’s US $7.7 billion purchase of software security firm McAfee, and with Ruby Lee, director of the Princeton Architecture Lab for Multimedia and Security at Princeton University, about the difficulties and benefits of putting security on a chip.

Interactive Map: What an E-Waste

Consumer electronics, critics charge, are designed for the dump. The latest gizmo enjoys a year or two of cutting-edge relevance and another two to five collecting dust. Then we throw it away, often to another part of the world. This map shows where e-waste originates and where it ends up.

Sponsored Whitepaper: Driving Business Success with Software Reuse

Component-Based Development (CBD) can help companies manage even the largest, most complex software projects. This paper describes four best practices examples where organizations have successfully deployed large, complex software projects, applications, and products composed of several hundred components and source code files, developed or maintained by several hundred to several thousand engineers on multiple sites.

Sponsored Whitepaper: What is Complete Critical Feature Analysis Solution & Why Do You Need it

Critical Feature Analysis (CFA) is a data analysis solution for understanding the impact and priority of recommended rule compliance issues in a design. CFA is one part of a comprehensive design for manufacturing (DFM) design flow. This five-part paper series examines the conditions that led to the development of recommended rules, and describes the process by which automated design analysis and rule verification can help designers optimize designs to the fullest and most efficient use of area, while still ensuring manufacturability. Part 1 explains the use of recommended rules and introduces the basic concepts of CFA

The Fastest Helicopter on Earth

Helicopters have many advantages, but speed is not one of them. Until now the greatest speed ever reached by a helicopter was no better than what a 1923 biplane could do. But Sikorsky Aircraft aims to shatter that speed record by combining active stabilization, software-simplified controls, and an unusual coaxial rotor design.
