Venus eruption, steel production and a new spacesuit: news

Scientific news from March 16, 2023:

In space: active volcanism on Venus: researchers have found traces of an eruption that occurred 33 years ago.

  • It has long been known that there are many volcanoes on Venus, but no evidence of their recent activity has yet been observed.
  • Analyzing images of Venus from 30 years ago, the researchers observed changes in the ground between the two passes of the Magellan probe.
  • The secondary crater expanded, and an outpouring of lava should have appeared.

In archeology: Long before the Romans, the ancient Iberians knew how to make steel almost 3,000 years ago.

  • Until now, it was believed that steel spread to Europe only during the Roman Empire and that no one could produce it before the Iron Age.
  • Analysis of the stelae, dated between the 13th and 8th centuries, shows that they are made of siliceous quartz sandstone, a rock that can only be worked with hardened steel.
  • The results show that the Iberian population had a knowledge of metals equivalent to an early technological leap, probably related to the dominance of crafts in the region and intercommunal exchanges.

In Space: New Space Suit: Find the prototype that the next astronauts will wear when they go to the Moon.

  • Prototype of the new suit was unveiled March 15, 2023 in Houston, Texas by NASA and Axiom Space.
  • These suits are designed for the Artemis 3 mission, scheduled for 2025, to land astronauts on the moon.
  • They must be able to withstand particularly harsh environmental conditions with insulating materials capable of withstanding tearing and dust.

High-Tech: GPT-4 has a new version for integrating an image into the ChatGPT artificial intelligence program.

  • OpenAI, a company that develops GPT (Generative PreTraining) models, unveiled the fourth version of its flagship technology on March 14, 2023.
  • This new version is capable of describing images.
  • It will be available in a paid version for integration into various applications.

En Santé: What is vernal keratoconjunctivitis, a rare and little-known eye disease that affects children?

  • Conjunctivitis, more often of allergic origin, can also occur in severe form – spring keratoconjunctivitis.
