Decades of data show the widespread belief that morality is waning is an illusion. Plus, the first images of the tallest tree in the Amazon and a ‘lost world’ of previously unknown microorganisms that once dominated complex life on Earth.
Efforts to discourage new smokers and help people to quit are bringing smoking rates down in many places, but it’s going to take more to put an end to tobacco smoking altogether.
The chemical composition of the Galactic halo star J1010+2358 shows extremely low sodium and cobalt abundances, different from most other halo stars, indicative of a very metal-poor star being seeded with elements from a pair-instability supernova.
Our experimental proof of chiral phonons demonstrates a degree of freedom in condensed matter that is of fundamental importance and opens the door to exploration of emergent phenomena based on chiral bosons.
Genome sequencing of nine individuals shows ancestry shifts in the Neolithization of northwestern Africa that probably mirrored a heterogeneous economic and cultural landscape in a more multifaceted process than observed in other regions.
Covalent organic molecules can be combined with ionic inorganic molecules to create a hybrid material demonstrating paradoxical mechanical properties in a bottom-up manner, enabling the manufacture of an ‘elastic ceramic plastic’.
