- In a study within the SPP 1833, biologically-relevant organic molecules have been detected in Archaean fluid inclusions, which most likely served as nutrients for early life on Earth. The scientists examined about 3.5 billion-year-old barites from the Dresser Formation in Western Australia. Helge Mißbach et al. published their results in Nature Geoscience, see the press release here.
- Writing in PNAS, scientists from Cologne university present important new constraints showing that plate tectonics started relatively slow, although the early Earth’s interior was much hotter than today.

Van Kranendonk, Hugh Smithies, Wolfgang Maier, Dieter Garbe-Schönberg (2021): Convective isolation of Hadean mantle reservoirs through Archean time. Proceedings of the National Academy of Sciences 118(2):e2012626118) Find the press release here.
- Dr. Michelle Gehringer and Achim Herrmann presented their research in a television report as part of the Sat1-Regionalmagazin. On November 26th, they featured in "Algen – die Superstars von morgen?" See the video here...
During the "GeoUtrecht 2020 - Virtual conference" (21-26 August 2020), C. Heubeck (Jena) and P. Mason (Utrecht) coordinated a session with the topic "Early Earth and Life: Insights from recent research in the Barberton Greenstone Belt". Contributions from our SPP were e.g.:
Heubeck, C., Janse von Rensburg, D., Reimann, S., Zametzer, A., 2020, Quartzofeldspathic Moodies Group sandstones (Barberton Greenstone Belt, ~3.22 Ga, South Africa and Eswatini) are derived from intra-BGB felsic igneous rocks, not from extra-BGB granites: Annual Meeting DGGV Utrecht, 24-26 August 2020, Utrecht, The Netherlands.

- Writing in Nature, SPP 1833 scientists present important new findings regarding the origin of oceans and life on Earth. Measurements on the oldest preserved mantle rocks from Greenland show that – contrary to previous assumptions – the elements necessary for the evolution of life were not delivered to Earth until very late in the planet’s formation (Mario Fischer-Gödde, Bo-Magnus Elfers, Carsten Münker, Kristoffer Szilas, Wolfgang D. Maier, Nils Messling, Tomoaki Morishita, Martin Van Kranendonk & Hugh Smithies (2020): Ruthenium isotope vestige of Earth’s pre-late-veneer mantle preserved in Archaean rocks. Nature 579, 240–244).

- In July 2019, researchers of the SPP 1833 in Cologne published their work about lunar age determination in Nature Geoscience. (Maxwell M. Thiemens, Peter Sprung, Raúl O. C. Fonseca, Felipe P. Leitzke and Carsten Münker (2019): Early Moon formation inferred from hafnium–tungsten systematics. Nature Geoscience DOI: 10.1038/s41561-019-0398-3) For a feature about the first landing on the moon 50 years ago, the University of Cologne filmed a video about the work for this article. Furthermore, the "Deutschlandfunk" broadcasted an interview with Carsten Münker.
- On November, 15th, 2018, Dr. Inga Köhler presented her children‘s book „How Earth became habitable - a journey through the Precambrian“ on invitation by the SPP 1833 at the University of Cologne. More than 150 children and parents attended the lecture and carefully listened to the adventures of the time travelling cat Portas meeting the first bacteria on Earth, learning, how water was delivered to Earth and why the oceans had various colours during Earth‘s history. From the accretion of Earth to the rise of oxygen in the atmosphere, the book covers the most important steps in creating an environment not only suitable for bacteria and other simple life forms, but also for mankind.
- A video about the field workshop 2017 in Australia was published by the coordination office. Watch it here:
- Dr. Sami Nabhan was invited to talk about his early earth research for the TV-programme BR-alpha. See his lecture at "Campus Talks" here
- Dr. Benjamin Eickmann and Professor Ronny Schönberg (both University of Tübingen) together with international collaborators published their latest work about Earth's oldest known oxygen in Nature Geoscience: "Isotopic evidence for oxygenated Mesoarchaean shallow oceans". Evidence for this early oxygen stems from 2.97 Ga old microbial carbonates of the Pongola Supergroup in South Africa, which were sampled by a co-author of this study, Professor Axel Hofmann of the University of Johannesburg, with the intention to investigate the redox-conditions during deposition of these sediments. Professor Hofmann was also one of the main leaders of the SPP1833 field trip to South Africa in August 2016, during which this outcrop - amongst many others - was visited. The article has been discussed at "Science Daily" and the TAZ commented that "stale air" can be worse: "Dit is die Baliner Luft!"...
- Prof. Sumit Chakraborty (RUB) published his work on the onset of plate tectonics in Nature Geoscience: "Emergence of silicic continents as the lower crust peels off on a hot plate-tectonic Earth". See the press release here...
