Recordings of oral presentations and posters are available to registrants until 11 August. To access them, go to Program by Day or Program by Theme, then to each sub-session, and click on the title of the presentation. Pre-recorded orals from remote presenters also remain available until 11 August.
We thank Targeted Films for producing Goldschmidt TV, which was a fantastic addition to the 2025 meeting in Prague. The videos brought fresh energy to the conference experience, offering attendees a dynamic way to engage with the science, speakers and stories behind the scenes.
Research at Goldschmidt2025 was widely reported in the international media with over 480 news articles published across 48 countries. View press releases issued at the conference and read a selection of related news articles below and in the Press Corner.
At the conference, a team of five bloggers shared their insights about the event and conducted interviews with several plenary speakers and conveners. Below are some of their stories, with many more available on the EAG Blog.
When the Southern Ocean Breathes🌊: Prof. Elisabeth Sikes Unlocks Antarctica’s Carbon Code 🔓 for Climate Control ♻️
[by Gaurav Kumar] For centuries, we treated the Southern Ocean, a vast, turbulent body of water encircling Antarctica, as a passive carbon sponge. Absorbing up to 40% of anthropogenic CO₂, it has been a lever in glacial-interglacial shifts...
An Early Career Researcher Perspective on Convening: Interview with Dr. Maria Dias
[by Sri Budhi Utami] Most people go to Goldschmidt to present their research, meet with colleagues, and hear about cutting-edge science. Sounds like a lot already, right? A select few choose to go further by becoming a convener of a scientific...
[by Siddhant Sharma] MIT's Tanja Bosak presented NASA Perseverance rover's discovery of unexpected iron-magnesium carbonates in Mars' Jezero Crater, revealing 3.8-billion-year-old water activity but no biosignatures of ancient life...
[by Bidisha Dey] The Goldschmidt Conference flags off with the Ice Breaker at the Prague Congress Center on a lazy sunny afternoon on the 6th of July. The city seemed relaxed and quite as I walked to the congress center through empty streets...

Deformation modulates helium diffusion behaviour in apatite
Utilising the apatite (U-Th)/He thermochronometer to infer the thermal histories of geologic materials requires understanding the factors that influence helium diffusion kinetics. Here, we demonstrate that...
Preservation of biosignatures in opal probed by infrared nanospectroscopy
Opal (SiO2·nH2O) is a common alteration mineral formed at the subsurface of planets that have experienced liquid water. Occasionally, opals found on Earth exhibit no discernible trace of biological remnants, but...
High δ26Mg in an early Cambrian palaeosol reveals a terrestrial clay mineral factory
The Mg isotopic signature of a palaeosol developed through the Great Unconformity has been analysed to elucidate the silicate weathering conditions on the Wyoming Craton during the early and middle Cambrian. The...
Solar neon dissolution into an ultramafic magma ocean
The solar-like neon isotopic signature of the mantle suggests the presence of a primitive reservoir. Its origin remains a puzzle, though the literature suggests that a primordial H2 and He-rich atmosphere captured from the...
Hydrothermal systems may have supplied essential phosphorus for early life
[Phys.org] Understanding where and in what quantities essential elements for life have existed on Earth's surface helps explain the origin and evolution of life. Phosphorus is one such element, forming the backbone of DNA, RNA, and cellular membranes. On Earth's surface, phosphorus is primarily preserved in rocks...
Rivers are exhaling ancient carbon — and climate math just changed
[Sciene Daily] Ancient carbon thought to be safely stored underground for millennia is unexpectedly resurfacing literally. A sweeping international study has found that over half of the carbon gases released by rivers come from long-term, old carbon sources like deep soils and weathered rocks...
What Greenland’s Ancient Past Reveals about Its Fragile Future
[Scientific American] Inside a tent fastened to the surface of Greenland’s ice sheet, the members of the GreenDrill expedition huddled around a drilling rig. The machine whined and shook as it spun. For days the drillers had been inching through ancient, solid ice to reach the rock below...
Astronomers discover 'raw materials for life' can form in planetary systems even before stars
[Space.com] Scientists are claiming a "cosmic chemistry breakthrough" following the discovery of a large "aromatic" molecule in deep space. The discovery suggests that these molecules could help seed planetary systems with carbon, supporting the development of molecules needed for life...
