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.

Study shows that just two American organizations are responsible for 54% of anti-vaccination ads on Facebook.
They target women and parents of young children, and carefully craft their messages to avoid being removed due to violation of Facebook’s new ad terms.
In contrast, pro-vaccination ads come from 83 healthcare organizations, and they do get removed due to violation of Facebook’s terms.
This shows just how easy it is to spread misinformation on Facebook, and how imperfect the platform’s terms and moderation mechanisms are.

New type of peanut allergy treatment could potentially be used to treat all food allergies in the future.
Study on 20 adults with severe peanut allergies shows that an antibody treatment, called etokimab, can stop a key molecule from activating the immune system.
Two weeks after just one injection, 11 people could eat a small serving of peanuts with no allergic reaction.
The treatment still has a lot of studies to go through before being approved.

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.
