Energy-harvesting card treats 5G networks as wireless power grids (3 minute read)

A team from Georgia Tech has unveiled a 3D-printed rectifying antenna that can harvest electromagnetic energy from 5G signals and use it to power devices. The playing card-sized device could turn 5G networks into wireless power grids. It is flexible and works well even when bent. Millimeter-wave energy harvesting has been possible for some time, but it hasn't been practical due to the large size of previous antennas. The device can harvest more than enough energy to power a range of small sensors and devices by using energy that would otherwise have been wasted.

Virgin Galactic unveils 'VSS Imagine,' the first of its next-generation spaceship series (4 minute read)

Virgin Galactic unveiled the VSS Imagine on Tuesday, the first of its next-generation SpaceShip III class of vehicles. It is the third spacecraft the company has built to date. The VSS Imagine was designed with lessons taken from flight testing on VSS Unity in mind. SpaceShip III class spacecraft can be manufactured faster and take less time to maintain between each flight compared to SpaceShipTwo class spacecraft due to their modular design. Virgin Galactic is on track for a test flight in May, after a delay in December.

Arm’s first new architecture in a decade is designed for security and AI (2 minute read)

Arm has announced its first new chip architecture in a decade. The Armv9 protects sensitive data with a secure, hardware-based environment. It uses dynamically created 'Realms' to protect data and code from the rest of the system. The Armv9 uses Scalable Vector Extension 2, which should benefit machine learning and digital signal processing tasks. CPU performance has increased by over 30 percent. All existing software will run on Armv9-based processors without any problems. The first Armv9-based silicon will ship before the end of the year.
