In this winning image, foster parent Helena Wehner and pilot Johannes Fritz guide northern bald ibises on a migration journey across Europe. Credit: Gunnar Hartmann This in-flight photo, taken by student Gunnar Hartmann, is the overall winner of Nature ’s #ScientistAtWork photo competition. In 2024, Hartmann joined a 50-day research expedition to support the annual migration of the northern bald ibis ( Geronticus eremita ) from southeast Germany to southwest Spain. These birds were hand-raised, and so are more than happy to follow their foster parents, who guide them in an aircraft. See more of the winning entries , selected by Nature ’s careers team. Nature | Leisurely scroll Researchers working on the Jiangmen Underground Neutrino Observatory (JUNO) experiment in Guangdong, China, have captured crucial details of how mysterious neutrino particles can switch between different types in flight . Neutrinos are so light that they were once thought to have no mass, and the standard model of particle physics doesn’t seem to explain why they do. Physicists use experiments such as JUNO to study how neutrinos ‘oscillate’, or change from one type to another, which is the first step in answering that question. …
