After two years of corona restrictions, it was ‘back to normal’ in 2022. Migration, elections, the history of slavery, Russia, and Ukraine were much-discussed topics. We compiled an overview of the most-read news items and other events of the past year.

Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

For 25 years now, each faculty has had an assessor, a student representing the interests of all the faculty’s students. Yet few students are aware of this.

The number of students suffering from stress and anxiety has decreased slightly compared with 2021. But around half still suffer from mental health problems. This is according to the National Mental Health and Substance Use Monitor.

Dennis Broeders has been appointed 'Global Chair' at the University of Bath for the year 2023-2024.

The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are very chaotic. As a result, researchers cannot predict with confidence where they will be in about 462 years. ‘That is astonishingly short,’ says astronomer Simon Portegies Zwart who collaborated on the r…

People in the Early Bonze Age used bronze artefacts as a means of payment. This is the conclusion reached by archaeologists Maikel Kuijpers and Catalin Popa in a PLOS ONE article published on 20 January. The discovery led to a surge of media reports.

An extraordinary encounter took place in 1911. American scientists discovered the last 'wild' Indian, from the Yahi tribe, who had lived in total isolation for years.
