MIT researchers have made a magnetic circuit that generates 0s and 1s without any electrical input.
The device consists of layered nanofilms of magnetic materials, separated into two halves by a nanometer-wide wall.
It is a promising new approach to building quantum computers, one that requires only the natural magnetic properties of materials to work.
Researchers compare it to a water pipe, in which you can control how the spin wave (quantum property of electrons) moves across magnetic materials.
So far it’s not usable, but researchers are planning to build a working circuit and perform basic calculations with it, to see if the device is viable.

New type of hologram uses ultrasound waves to trace 3D objects with a tiny polystyrene grain.
It can trace an object within one-tenth of a second, making the movement of the grain completely invisible to our eyes, and leaving just the visualised object.
The device relies on two horizontal plates which control the movement of the grain, and built-in LED lights that add color to the objects.
This is a promising technology which, in the far future, could lead to 3D holograms which look like real objects.

Prices of lithium have dropped because there’s too much of this metal on the market -- but the oversupply is in ‘technical-grade’ lithium, used for small devices.
The supply of high-quality lithium, good enough to make batteries for electric vehicles, is actually locked up until 2024.
Which means the price of the metal is dropping, but factories need to keep ramping up production to meet future demand for high-quality lithium.
Some analysts say that the future supply of battery-grade materials is in doubt, others see this as a momentary slump, and look toward a bright future.

China wants to lead the world in terms of several most promising technologies -- AI, blockchain, fintech, and 5G networking.
The state plans to make their AI industry worth $147.7 billion by 2030, and they’re already the first country to roll-out countrywide AI systems.
In terms of mobile payments, they are already leading the world, since cash and credit cards are already a thing of the past in China.
Additionally, three out of 5 top smartphone vendors are Chinese, and the government plans to invest heavily in blockchain.
Lastly, China turned 5G networks on ahead of their 2020 date, and will account for the most 5G connections by 2025, more than North America and Europe combined.

Stacks of charged electrochemical plates, under low voltage, hold promise to be the most cost-effective way to capture CO2, useful in a variety of applications.
The method is precise and flexible, works in any concentration of CO2, and could be used to produce CO2 for soft-drink bottling plants, or even to produce fuel.
All other methods require additional thermal, pressure, or chemical inputs to work — this method only needs a source of electricity.
Researchers who discovered this method have set up a company, aiming to commercialize the project.
