When two worlds collide, they leave more than the shambles of dusty ejecta. Astronomers have detected light from a post-collision remnant, providing the best evidence so far for planetary-scale collisions in exoplanetary systems.
The COVID-19 pandemic highlighted the need to understand the emergence of viral variants, given that these can have implications for vaccination success. A bioinformatics tool offers a way to predict viral evolution.
Human footprints might be the oldest direct evidence that people lived in the Americas thousands of years earlier than thought. Plus, gene editing makes chickens flu-resistant and how to lower the risk of a Nipah virus pandemic.
A raft of alterations to the pig genome — removing three antigen-encoding genes, adding seven human genes and eliminating a retrovirus — allows kidneys to be transplanted into monkeys, with implications for clinical trials.
By bearing firsthand witness to how the climate crisis is affecting life and livelihoods, their fieldwork directly informs policy to protect vulnerable sites.
Recordings of human voices evoke more fear among animals living in the South African savanna than do snarls from lions. Plus, an economic historian who mined 200 years of gender pay gap data wins a Nobel Prize and researchers are seeking to understand the human body’s heat limit.
