Wireless charging is a great idea in theory: You can just place your device on a charging mat without having to mess with any wires. But it still doesn’t solve the main hassle of charging in the first place, which is the requirement to leave your device in one place. But now, scientists may have found the answer to that problem using principles from quantum mechanics.
Currently, wireless, or inductive, charging uses an electromagnetic field to transmit energy over very short distances. That’s why your phone, or whatever device you’re charging wirelessly, must remain near a wireless pad in order to actually charge. But Shanhui Fan and his team at Stanford University have published an article in Nature that details a wireless charging system that works even when the charger and device are a meter apart. You can also move around the device while it’s being charged without interrupting the power transfer.
It works by using a principle of quantum mechanics called parity-time symmetry to create a charger with a self-adjusting power flow. A connected amplifier automatically controls the flow of power between the transmitter and receiver. As a device moves further away from the charger, the power levels adjust automatically to ensure an even and uninterrupted flow of current.

Shimon—a four-armed marimba playing robot—has been around for years, but its developers at Georgia Tech have recently taken this futuristic musical machine to the next level. Using deep learning, the robot can now study large datasets from well-known musicians, and then produce and perform its own original compositions.
Shimon was originally developed by Gil Weinberg, director of Georgia Tech’s Center for Music Technology. Under its original programming, the robot was capable of improvising music as it played alongside human performers, using an “interestingness” algorithm to make sure it wasn’t just copying its bandmates. But now, thanks to the efforts of Ph.D. student Mason Bretan, Shimon has become an accomplished composer, capable of autonomously generating the melodic and harmonic structure of a song. And you know what? Shimon’s songs are actually quite good!

Meanwhile there was a Big New Development. The Internet and digital technology came of age. And here’s the thing. Digital artefacts – whether they’re an algorithm, a website, an app or a coding language – are always and everywhere potential public goods. Once produced digital artefacts are essentially costless to replicate which raises the question of whether they can or should be made freely available to all.
Digital public goods in the age of the data revolution.

The CASTC is beginning advanced research on combined cycle engines that can takeoff from an airport’s landing strip and fly straight into orbit. Claimed to have operating status by 2030, this pace plane could enable space tourism.
The China Aerospace Science and Technology Corporation (CASTC) wants to re-invent how we travel in space.
