X-ray Movies: Imaging with Ultrashort Electron Beams
By Larry Hardesty
Ultrashort bursts of electrons have several important applications in scientific and industrial imaging, but producing them has typically required a costly, power-hungry apparatus about the size of an automobile.
Medical Imaging Chip Volume to Soar
By Robbie Galoso and Tom Hackenberg, IHS Markit
Given the medical imaging industry's growing requirements for power savings, higher resolution and the need to support integrated security and communications, the unit volume of semiconductors used in medical imaging is expected to increase at a five-year compound annual growth rate ...
MIT Unveils Nanolithia Cathode Battery
Cambridge, MA — Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their weight. But such batteries have some pretty serious drawbacks: They waste much ...
Decawave UWB Chips Underpin Pixie's Object Location
By Mickael Viot, Vice President of Marketing, Decawave
Pixie Points are Bluetooth tags that can be attached to keychains, wallets and other other easy-to-lose items in order to keep track of them remotely. Launched by Pixie in 2015, their small, friendly design has allowed them to quickly find a niche in the market. In order to create these ...
A Nanotechnology Approach to Scavenging Wind and Solar Energy
By Michael Berger, Nanowerk
More than 60 research groups worldwide are now developing variations of the triboelectric nanogenerator (TENG), which converts ambient mechanical energy into electricity for powering wearable electronics, sensor networks, implantable medical devices and other small systems.
Parallel Programming Made Easy
By Larry Hardesty, MIT News Office
In theory, a program on a 64-core machine would be 64 times as fast as it would be on a single-core machine. But it rarely works out that way. Most computer programs are sequential, and splitting them up so that chunks of them can run in parallel causes all kinds of complications.
Computing Threads and Sewing Circuits
By Mike Skinner
In what appears to be a milestone for the wearable electronics market, researchers at the Ohio State University (OSU) have developed a process of embroidering circuits into clothing with 0.1mm (0.004 in.) precision. This level of accuracy now makes wearable circuitry, clothes that gather ...
Video Recording Becomes Real: Stand up and Cheer
By Walter Salm
Ray Dolby is perhaps best known for his revolutionary audio noise-suppression system — a technology that dramatically lowered the background hissing noise that was an unavoidable part of every tape recording. Then a related noise suppression system was developed for FM broadcast stations and for ...
5D Data Storage Could Record the History of Humankind
By Glenn Harris, University of Southampton
Scientists at the University of Southampton have made a major step forward in the development of digital storage, which is capable of surviving for
billions of years
. Using nanostructured glass, a team of scientists from the university's Optoelectronics Research Centre (ORC ...
Demand for Quantum Dots to Increase 20-Fold Over Next Decade
Quantum dots (QDs), synthesized miniature semiconductor crystals, are teetering on the edge of mass adoption. From a shaky entrance in bioscience in the early 1990s to a growing popularity in consumer electronics and manufacturing, the time may finally be right for the quantum dot.
From "Made in China" to "Made in the Cloud"
By Mitch Free, CEO, CloudDDM
Additive manufacturing, commonly referred to as 3D printing, has moved beyond being simply a great technology for rapidly producing prototypes; it has now become a viable manufacturing option. Additive manufacturing is impacting supply chains in the way companies design and bring products to market ...
Time Synchronization Using Distributed Data Acquisition
By Stew Thompson, Marketing Specialist, CAS DataLoggers
When the time between a PC and Delphin data logger differs by a significant duration, measurement data cannot be displayed in the form of online trend diagrams as it normally can. Therefore it is essential to ensure time synchronization between the data logger and the PC. Here, we look at four ways ...
The 7 Deadly Sins of Incident Response
By Brandon Tansey, Security Research Engineer, Lancope
The seemingly endless barrage of attacks on government and enterprise networks has made it clear that organizations need to be much more proactive when it comes to security. Deploying perimeter defenses like firewalls and antivirus, and expecting them to keep attackers off of your network, has become ...
Photovoltaic Power Is Coming to the French Island of Corsica
By Michael Lippert
Photovoltaic power is natural and can be cost-effective. And photovoltaic power through lithium batteries is coming to the French island of Corsica. Two PV power-generating plants with lithium battery power storage will be installed on Corsica and be made part of the Corsican operating power grid ...
Practical Fusion Energy Targeted at Sandia and Rochester LLE
Albuquerque, NM — A two-year, $3.8 million award has been received by Sandia National Laboratories and the University of Rochester's Laboratory for Laser Energetics (LLE) to hasten the day of low-cost, high-yield fusion reactions for energy purposes.
JTAG/Boundary Scan: Updated Standards
Peter van den Eijnden, JTAG Technologies (
Prompted by a change in device packaging — from through-hole to surface-mount-technology (SMT) packaging — that occurred almost 30 years ago, a group of like-minded test engineers met to consider the impact that these modified packaged parts would have on testing their forthcoming assemblies ...
The Passive Optical LAN: Providing Enterprises Mega Improvements in Network Performance and Flexibility
By Ed Sullivan
Enterprise networks around the world are becoming progressively choked by the integration of bandwidth-hungry Internet-based applications. The growing usage of streaming video content, integration of digital voice services into the LAN, video conferencing and other online activities ...

Anyone for Surface Noise?
By Walter Salm
Back in the middle 1960s, there was a lot of talk about creating digital audio. At the time, there were at least three major roadblocks to making this happen: appropriate media, hardware, and basic knowledge. The only digital media that worked was high-speed magnetic tape. There was ...
