Questions & Answers

Q: How can scientists create customized crops using artificial genetics?

Scientists have developed artificial genetics for yeast, paving the way for optimized and customized agricultural crops. By streamlining the genome and removing unnecessary DNA, researchers aim to create crops tailored to specific needs.

Q: How is AI being used to map new molecules?

AI is proving to be better than humans in mapping new molecules. By asking the right questions, AI algorithms can predict and discover new variations quickly, potentially revolutionizing materials sciences and pharmaceuticals.

Q: How is ancient DNA being recovered?

Ancient DNA has been recovered from sediment layers in Greenland rather than fossils. The DNA binds to minerals in the sediment, providing insights into the past flora and fauna.

Q: What does the discovery of phosphorus on Enceladus mean?

Phosphorus, a crucial element for life, has been found on Enceladus, increasing the moon's potential to support life in its subsurface ocean.

Q: Why is Earth's core rotation slowing?

Interactions between the mantle and core, which are not perfectly spherical, cause variations in Earth's rotation. This suggests the Earth's magnetic field may be undergoing a reversal.
