Hologram-like device animates objects using ultrasound waves

theguardian.com
  • 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.

Lithium producers hit by first big downturn of electric vehicle era

reuters.com
  • 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.

Majority of anti-vaxx ads on Facebook are funded by just two organizations

theguardian.com
  • 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.

Antibody injection stops peanut allergy for 2 to 6 weeks, study shows

med.stanford.edu
  • 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 throws its weight behind A.I. and blockchain as it aims to be the world’s tech leader

cnbc.com
  • 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.
