Researchers from Aalto University in Finland have set a new world record for microwave detection. They developed a device that has 14 times higher energy resolution of thermal photodetection.

A new technique from researchers at Penn State University demonstrates that atoms could one day become the building blocks of circuits in quantum computers. The team used a combination of lasers and microwaves to squeeze more quantum computing power into a smaller space and with greater control than ever before.

A new patented MIMO antenna system that fits inside a laptop’s hinge cavity and can replace as many as 5 separate antennas found in a standard laptop. It was developed by Smart Antenna Technology (SAT), a spin-off company that was started by scientists at the University of Birmingham.

HP has announced it is recalling lithium-ion batteries that are used with certain HP and Compaq computers. The battery packs can overheat, posing fire and burn hazards. HP has received seven reports of the battery packs overheating, melting or charring, including four reports of property damage of about $4,000 total.

A new microchip containing 1,000 independent programmable processors but is very energy efficient. The “KiloCore” chip can process 1.78 trillion instructions per second, contains 621 million transistors, and could be powered by a single AA battery.

Silicon microchips just got a boost from the power of sound. A team of Yale scientists developed a new waveguide system that can precisely control the way that light and sound waves interact on a chip. This innovation could become the foundation for new lasers, fiber-optic communications, and signal processing technologies.

IBM has achieved a breakthrough that could dramatically expand the applications for Phase-Change Memory (PCM) storage. This optical storage technology has already been used in Blue-ray disks and elsewhere for the last 15 years, but now researchers have dramatically increased the capacity.
