United Nations weapons inspectors could have an easier time in the future locating nuclear materials. Researchers at the University of Nebraska-Lincoln developed a fingertip-sized neutron detection device built around a boroncarbide semiconductor diode. The highly sensitive device can detect neutrons emitted by materials that fuel nuclear weapons. "This is a leapfrog technology in neutron detection," said Peter Dowben, UNL physicist who first fabricated a boron carbide semiconductor. Using Dowben's semiconductor, the research team built a detector about the size of one LEGO® block, which the researchers say is more efficient, lighter, and tougher than existing detectors. It can be powered with small batteries or even solar cells and can withstand corrosion and extremely high temperatures, says Brian Robertson, associate professor of mechanical engineering at UNL. The device could also be used to monitor nuclear weapons storage and other national security applications. Patents on the semiconductor process and the detector are pending.

When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
