Science: Fossil Mystery Solved, A Silk Mother Of Pearl, Bolivian Amazon
The puzzle of Palaeospondylus – Over a hundred years ago, archaeologists discovered fossils of the aquatic animal Palaeospondylus. But since then researchers have been unable to place where this animal sits on the tree of life. Now, new analysis of Palaeospondylus’s anatomy might help to solve this mystery.

10:51 How lasers revealed an ancient Amazonian civilization
Archaeologists have used LiDAR to uncover evidence of an ancient civilization buried in the Bolivian Amazon. The team’s work suggests that this area was not as sparsely populated in pre-Hispanic times as previously thought.

Science: Galaxies Without Dark Matter, High Helium Levels, Solar Energy Jump
Dark matter makes up most of the matter in the Universe, and is thought to be needed for galaxies to form. But four years ago, astronomers made a perplexing, and controversial discovery: two galaxies seemingly devoid of dark matter.
This week the team suggests that a cosmic collision may explain how these, and a string of other dark-matter-free galaxies, could have formed.

A survey of cell types across tissues as part of the Human Cell Atlas, mapped with single-cell transcriptomics in three papers in this issue, lays the foundation for understanding how cellular composition and gene expression vary across the human body in health, and for understanding how genes act in disease.

Nova explosions occur when a runaway thermonuclear reaction is triggered in a white dwarf that is accreting hydrogen from a companion star. The massive amount of energy released ultimately creates the bright light source that can be seen with a naked eye as a nova. But some of the energy has been predicted to be lost during the initial stages of the reaction as a flash of intense luminosity — a fireball phase — detectable as low-energy X-rays. In this week’s issue, Ole König and his colleagues present observations that corroborate this prediction. Using scans taken by the instrument eROSITA, the researchers identified a short, bright X-ray flash from the nova YZ Reticuli a few hours before it became visible in the optical spectrum. The cover shows an artist’s impression of the nova in the fireball phase.
