GS and EAG announce virtual Goldschmidt Conference
In light of the COVID-19 pandemic, the GS and EAG have determined that the 2020 Goldschmidt Conference cannot be held as scheduled in Honolulu. Instead, Goldschmidt will become a virtual meeting this year.
The conference will be held entirely online to keep vital science communication flowing even while travel is restricted. In the coming days, we will be announcing more details about the conference schedule, registration, early career events, and more.

Changes to the Geochemical Perspectives Letters editorial board
The Geochemical Perspectives Letters editorial board are very pleased to welcome Anat Shahar (Carnegie Institution for Science) and Gavin Foster (University of Southampton) to the team.
Anat Shahar's research focuses on understanding how stable isotopes can inform our understanding of the processes occurring and conditions present from the early solar system through planetary formation, differentiation, and evolution. Gavin Foster is an isotope geochemist and in his research uses boron and other elements to reconstruct past climates so as to better understand our future.
The board would also like to take this opportunity to thank departing editors, Ariel Anbar and Wendy Mao, for their hard work and their immense contributions to the success of the journal.

The EAG endorses the Attarik Foundation
The EAG is proud to announce its endorsement of the Attarik Foundation for Meteoritics and Planetary Science.
The Attarik Foundation, an autonomous and non-profit association, aims at promoting the science of meteorites, planets and astronomy among researchers from public or private institutions, students, teachers, high school students, public authorities and the general public, in particular in the Arab world and African continent countries.

Lab Corner: DIY for the field
Last month in 'Lab Corner', we featured some tips and tricks for repurposing everyday items for geochemistry. In this next contribution, microbiologists from the University of Oklahoma put together an ingenious gadget for homogenizing biological samples, and a glaciologist from Cardiff University repurposes a climbing frame for fieldwork in Greenland.

Sun, sand and speed dating in Belgium – ChemCYS 2020
[By Camille Gaulier] Welcome to Blankenberge! A famous Belgian seaside resort by the North Sea, meeting place of families and old people in summer, and of young chemists in wintertime for the renowned ChemCYS Conference. The 15th edition of the CHEMistry Conference for Young Scientists 2020 (ChemCYS 2020) took place this February in the gigantic Floréal...

Mantle cooling causes more reducing volcanic gases and gradual reduction of the atmosphere
The early atmosphere contained negligible O2 until the Great Oxidation Event (GOE) around 2.4 Ga, but evidence suggests that production of photosynthetic O2 began hundreds of millions of years earlier. Thus, an ongoing debate...

Concentration of meteoritic free organic matter by fluid transport and adsorption
Carbonaceous chondrites contain many abiotic organic compounds, some of which are found in life on Earth. Both the mineral and organic matter phases, of these meteorites, have been affected by aqueous alteration processes. Whilst...

Sulfur loss from subducted altered oceanic crust and implications for mantle oxidation
Oxygen fugacity (fO2) is a controlling factor of the physics of Earth’s mantle; however, the mechanisms driving spatial and secular changes in fO2 associated with convergent margins are highly debated. We present new thermodynamic...

Forty-year pollution history of microplastics in the largest marginal sea of the western Pacific
Marine sediments have been considered to be a major sink for microplastics, yet the pollution history of microplastics recorded in these sediments remains poorly understood. Using a combination of 210Pb chronology and...

Volcanic activity helped trigger Triassic climate change, study says
[The Guardian] Volcanic eruptions played an important and direct role in triggering the extreme climate that killed off swathes of life at the end of the Triassic period 201m years ago, researchers have found. Experts say they have discovered bubbles of carbon dioxide trapped in volcanic rocks…

No star, no problem: Radioactivity could make otherwise frozen planets habitable
[Science Magazine] Not too close, but not too far. That’s long been the rule describing how distant a planet should be from its star in order to sustain life. But a new study challenges that adage: A planet can maintain water and other liquids on its surface if it’s heated, not by starlight, but by...

The right dose of geoengineering could reduce climate change risks
[Science Daily] Stratospheric aerosol geoengineering is the idea that adding a layer of aerosol particles to the upper atmosphere can reduce climate changes caused by greenhouse gases such as carbon dioxide. Previous research shows that solar geoengineering could be achieved using...

Forty years of ice-core records of CO2
[Nature] In the ancient ice sheets near Earth’s poles, tiny bubbles trapped in the compacted layers of snowfall provide a natural archive of air from ages past, but one that is not straightforward to read. Forty years ago, the glaciologist Robert Delmas and colleagues developed a technique for...

Scientists identify rain of molten iron on distant exoplanet
[The Guardian] Wasp-76b is what astronomers call an exoplanet, one that orbits a star outside our solar system. Scientists have discovered that the local weather conditions include 2,400C temperatures, winds in excess of 10,000mph and a steady pelting of iron rain. The observations of...

Mercury's 400 C heat may help it make its own ice
[Phys.org] It is already hard to believe that there is ice on Mercury, where daytime temperatures reach 400 degrees Celsius, or 750 degrees Fahrenheit. Now an upcoming study says that the Vulcan heat on the planet closest to the sun likely helps make some of that ice. As with Earth,...

30 years of the iron hypothesis of ice ages
[Nature] Thirty years ago this month, John Martin proposed a solution to one of the biggest mysteries of Earth’s climate system: how was nearly one-third of the carbon dioxide in the atmosphere (about 200 gigatonnes of carbon) drawn into the ocean as the planet entered the most recent ice age,...
