During my visit to the German Embassy in Brasília, I emphasized our commitment to deepen cooperation with Latin America, with Brazil as a key partner in science, innovation and climate research. I truly value the spirit of collaboration that drives this partnership.

Gutso, aber zu wenig

Ich lasse das mal hier: In den USA müssen ab jetzt alle Presseartikel und TV-Sendungen über das Militär vorher dem Verteidigungs-, ich korrigiere, Kriegsministerium zur Freigabe vorgelegt werden.

Unfassbar: Das Pentagon ordnet an, dass sich Medien den Inhalt ihrer Berichte künftig genehmigen lassen müssen. Es ist dasselbe Land, das eins Watergate aufdeckte und Snowdens Enthüllungen veröffentliche. www.faz.net/aktuell/feui...

Last night, we continued a tradition that dates back to 1977 — the famous Kohl and Pinkel party! This year's theme was medieval, filled with knights, dragons and magicians! The night was filled with laughter, legend, and a new Kohl Queen! 🏹⚔️ Read more at: www.fkf.mpg.de/8759364/2025...

We mourn the passing of Prof. Hans-Joachim Queisser (1931–2025), one of the founding directors of our institute. A pioneer of semiconductor physics and co-creator of the Shockley–Queisser limit, his vision shaped generations. We will remember him with deep gratitude. www.fkf.mpg.de/8744972/2025...

New special issue on "Open Large Language Models for Scientometrics": www.mdpi.com/journal/metr... #scientometrics #bibliometrics We are looking forward to high-quality submissions.

Several #KB partners have collaborated on an analysis of #openalex data quality aspects (here in particular the completeness of references as a fundamental backbone for bibliometric databases), more contributions to follow! link.springer.com/article/10.1...

The special track on Open Research Information at @stienid2025.bsky.social is open to submissions via the regular conference submission tool.

Robin Haunschild, Lutz Bornmann: Paper self-citation: An unexplored phenomenon https://arxiv.org/abs/2503.04324 https://arxiv.org/pdf/2503.04324 https://arxiv.org/html/2503.04324

found cases where paper self-citations occur due to publisher-made highlights promoting and citing the paper. We analyzed the self-citing papers according to selected metadata. We observed accumulations of the number of self-citing papers [3/4 of https://arxiv.org/abs/2503.04324v1]

across publication years. We found a skewed distribution across countries, journals, authors, fields, and document types. Finally, we discuss the implications of paper self-citations for bibliometric indicators. [4/4 of https://arxiv.org/abs/2503.04324v1]
