A new study published in Conservation Biology shows that geotagged social media photos can significantly improve biodiversity datasets, especially in regions underrepresented in global monitoring efforts. Led by scientists from the German Centre for Integrative Biodiversity Research (iDiv), the Friedrich Schiller University Jena, the Helmholtz Centre for Environmental Research – UFZ, and Monash University, the team integrated Global Biodiversity Information Facility (GBIF) occurrence records with public images of the tawny coster butterfly (Acraea terpsicore) from Flickr and Facebook, and saw a 35% increase in total observations.

A study led by the Institute for Neurosciences CSIC-UMH in Spain has identified an essential protein responsible for the slow and sustained release of oxytocin in the brain, a process that is fundamental for the regulation of social behavior. This work, published in Communications Biology, provides new insights into how the brain maintains basal levels of this hormone and how subtle adjustments in its release modulate sociability.

Certain markers of high status may more strongly boost attitudes towards women versus men, and low status markers may more strongly worsen attitudes towards men versus women—with both findings more pronounced in countries with more conservative gender norms. Marie Isabelle Weißflog of Ruhr-Universität Bochum, Germany, and the University of York, U.K., and colleagues present these findings in the open-access journal PLOS One on February 18, 2026.
