An in-depth new survey from @insidehighered.com documents opinions of college & university presidents on a range of issues, including how the Trump admin is affecting their campuses.

For more on the administration’s impacts on higher education, check out our recent report: eos.org/report/the-s...

Acidifying Seas Are Wearing Away at Underwater Archaeology - Eos Marble, limestone, and other carbonate rocks used throughout antiquity could start dissolving as oceans soak up more carbon dioxide.

The findings paint a concerning picture for the integrity of many underwater cultural sites.

A New 3D Map Shows Precipitous Decline of Ugandan Glaciers - Eos A team of dozens spent weeks in the Rwenzori Mountains capturing drone photography, GPS coordinates, and ground-penetrating radar data to document glacial retreat.

Researchers surveyed ice on the three tallest peaks of the Rwenzori mountain range. eos.org/articles/a-n...

Antarctic Peninsula Faces Starkly Different Futures, Depending on Decisions Made Today - Eos A study reveals interconnected changes under three emissions pathways and describes the emerging challenges facing Antarctic fieldwork.

A new study shows how Antarctic Peninsula systems will be affected under different emissions scenarios. 🧪

Research led by @iceybethan.bsky.social from @ncl-geography.bsky.social with colleagues from @bas.ac.uk, @pml.ac.uk, and elsewhere. eos.org/articles/ant...

Democracy and Education Increase Women’s Belief in Climate Change - Eos The finding, which focuses on lower-income countries, could help inform plans to shrink the global climate knowledge gender gap.

Research led by @marijaverner.bsky.social of @yaleclimatecomm.bsky.social found that in countries with lower GDP, greater access to education increased the % of women and gender minorities who think that climate change is driven by human activity.

Snowball Earth’s Liquid Seas Dipped Way Below Freezing - Eos Iron isotopes show that salty seawater pockets beneath the ice were as cold as −15°C.

Researchers reported the first measured sea temperature from a snowball Earth episode: −15°C. If this figure holds up, it will be the coldest measured sea temperature in Earth’s history.

A Long-Term Look Beneath an Antarctic Ice Shelf - Eos More than 4 years of data from a borehole in the Ross Ice Shelf reveal supercooled water and more.

The first long-term hydrographic dataset from under an Antarctic ice shelf reveals supercooled water intrusions, distant polynya influences, and interannual variability in circulation patterns.

COVID-19 Shutdowns Saw Human Emissions Slow, but Atmospheric Methane Surged - Eos An uptick in wetland emissions, as well as a scarcity of atmospheric OH radicals, contributed to the counterintuitive methane spike.

COVID-19 gave our environment an emissions respite, but an atmospheric methane surge had scientists puzzled. New research takes a stab at explaining the spike.

New Evidence Points to Venusian Lava Tubes, and They’re Really Big - Eos Researchers bring new life to 30-year-old Magellan data to unearth the first direct evidence of the long-hypothesized structures.

“Look, this is what we found,” said one of the researchers. “It’s gigantic.”

Acidifying Seas Are Wearing Away at Underwater Archaeology - Eos Marble, limestone, and other carbonate rocks used throughout antiquity could start dissolving as oceans soak up more carbon dioxide.

Climate change could be speeding up the erosion of underwater structures, such as Underwater Archaeological Park of Baia. eos.org/articles/aci...

Global fatal landslides in 2025 plotted using pentads. The long term average and the exceptional year of 2024 are included for reference.

In 2025, I recorded 663 global fatal landslides, costing 5,091 lives, the second highest total on record.

COVID-19 Shutdowns Saw Human Emissions Slow, but Atmospheric Methane Surged - Eos An uptick in wetland emissions, as well as a scarcity of atmospheric OH radicals, contributed to the counterintuitive methane spike.

Scientists are analyzing OH radicals to better understand a 2020 spike in atmospheric methane that occurred despite decreased global greenhouse gas emissions overall.

New Evidence Points to Venusian Lava Tubes, and They’re Really Big - Eos Researchers bring new life to 30-year-old Magellan data to unearth the first direct evidence of the long-hypothesized structures.

“When you have improvement in the capability of processing your data, you can give a new life to old data, and this is one of those cases.”

What do BLOBs Have to Do with Earth’s Magnetic Field? A Lot, It Turns Out - Eos Enormous provinces of superheated mantle exert a powerful influence over our planet’s magnetic field, researchers have discovered.

Giant BLOBs are pulling the strings of Earth’s magnetic field.

Scientists Create the First Map of Deep Earthquakes Beneath Continents - Eos Scientists once thought Earth’s continental mantle was too weak for earthquakes. A new global map of 459 deep tremors suggests otherwise.

Southern Idaho emerged as the most prolific mantle-quake region in the lower 48 states.

When the Snow Melts, Microbes Bloom - Eos A new study illuminates a complex and changing world of microbes and nitrogen cycling that occurs during the winter.

A new study examines what’s going on under the snow in the winter.

Seeing all the anti-science actions by the fed gov't is “discouraging, and that’s one of the reasons why I’m here. How can I help to maybe turn the ship around?”

Rally-goers refuse to give in to despair, keeping hope, and the fight, alive ✊🧪

Insights for Making Quick Clay Landslides Less Quick - Eos In a quick clay landslide, solid soil liquefies suddenly, sometimes washing over entire towns. New modeling examines what kinds of salts could help stabilize these clays.

Quick clay landslides can liquefy entire hillsides with little warning. In far northern countries where they occur, researchers are searching for new ways to stabilize soils, digging down to the molecular level.

Thousands Rally to Support the Need for Science in a Democracy - Eos Dozens of Stand Up for Science gatherings nationwide focused on the importance of science for federal policymaking.

“We’re fighting to save science, we’re fighting to protect health, and we’re fighting to defend democracy,” @cdelawalla.bsky.social, founder of @standupforscience.bsky.social, about today’s Stand Up for Science rallies. eos.org/articles/tho...

Engineering a Cleaner Way to Extract Lithium - Eos The new chemical solvent technique could cut water use, speed extraction, and unlock reserves like California’s Salton Sea.

Today’s lithium often comes from massive evaporation ponds in arid regions. A new technique instead uses a reusable solvent that could pull lithium from brine faster and with lower environmental impact.

Bacteria Decide the Ocean’s Dissolved Organic Carbon Abundance - Eos Dissolved organic carbon prevalence follows from how many bacteria are around to eat it, modeling suggests.

It’s not what you have, it’s how you use it—even when it comes to the distribution of dissolved organic carbon in the ocean. The type of DOC is less important than how many bacteria are around to eat it, modeling suggests.

Salt of the Earth: Vast Underground Salt Caverns Are Preserving Our History—and Just Might Power Our Future - Eos From health spas to film storage, salt mine caverns have been put to use in surprising ways—and they’re now poised to contribute to the generation and storage of clean energy.

Salt mine caverns have become health spas, Hollywood storage vaults, and even amusement parks. But they’re also poised to contribute to a cleaner energy future.
