ALT How animals sense Earth’s magnetic field is one of biology’s enduring mysteries. Researchers have now identified superparamagnetic macrophages in the livers of rock pigeons (Columba livia) to be crucial for magnetic sensing. The finding uncovers an unexpected role for immune cells in sensory perception and may fundamentally change our understanding of animal navigation. Photo: Andreas Teichmann/laif/Redux

ALT The image presents a bar graph titled "Women are the victims in most partner homicides." It compares the percentages of male and female victims of partner homicides across a selection of 9 OECD countries.
