Scientists have long thought that our solar system's ocean worlds, such as Jupiter's moon Europa and Saturn's moon Enceladus, may harbor extraterrestrial life in the form of microbes. But detecting it could be a challenge because missions to ocean worlds have relied on probes, not landers. Probes pass only through a planet's or moon's atmosphere, kilometers away from the surface and interior. Spacecraft such as Europa Clipper (like Cassini before it) stay even farther away, not even entering the moon's exosphere.

Sarakiniko, a stunning geological landmark on the aegean island of Milos, Greece, is under imminent threat. Known for its breath-taking white tuff formations built by the deposition of submarine volcanic eruptions and sculpted by wind and water over millions of years, this site serves as both a natural laboratory for geoscience and planetary research and a worldwide significant geoheritage site. However, recent construction of a large-scale hotel and plans for expansion to multiple constructions in the near future within Sarakiniko is causing irreversible damage, jeopardizing not only its aesthetic and cultural value but also its scientific importance.

March 21, 2025, the "World Day for Glaciers", is part of the UN International Year for Glaciers' Preservation." Rapid and accelerating glacier loss this century led to this day. In 2023 and 2024 for the first time all 58-reporting Global Reference glaciers had a negative mass balance. Acceleration of glacier's disappearing led to creation of an extinct glacier data layer in GLIMS global glacier inventory.

On 9 March, a French researcher traveling to a science conference near Houston, Texas, was denied entry to the United States and expelled back to France. The scientist, on assignment for France's National Center for Scientific Research (CNRS), was allegedly pulled aside for a random security check. U.S. authorities said they found private messages on the scientist's devices expressing a personal criticism of the Trump administration's treatment of scientists and scientific research.

Heterotrophic aquatic bacteria require carbon and nutrients to survive, and consequently, remove dissolved nutrients and organic matter from streams - acting as a form of water filter. While this process is well understood, it is less certain how the balance of nutrients and organic matter, as well as variation in organic matter composition, impacts the efficiency of nutrient removal by heterotrophic bacteria.

Glaciers are important indicators of climate change. A recent study published in the leading journal Science shows that glaciers in the tropical Andes have now retreated further than at any other time in the entire Holocene - which covers the whole history of human civilisation since the invention of agriculture. These findings are likely to resonate beyond the scientific community, as they strongly support the lawsuit filed by a Peruvian farmer against the energy company RWE, which has returned to court this week.Paleoclimatologists can determine how long bedrock beneath a glacier has been covered by ice using measurements of specific isotopes. When rock surfaces are exposed, isotopes such as carbon-14 and beryllium-10 form due to bombardment by cosmic radiation. If, however, the rock is covered by an ice sheet, it is shielded from this radiation, and these unstable isotopes gradually disappear through radioactive decay (with half-lives of 5,700 and 1.4 million years, respectively). This method, known as cosmogenic radionuclide dating, has been well-established for decades. I first encountered it myself 23 years ago during an excursion with glacier experts to New Zealand's Southern Alps.

The Bureau of Reclamation released its March 24-Month study last Friday and just like last month, the forecast is for big trouble in the Colorado River Basin. Under the "Most Probable" scenario, the ten-year cumulative flow at Lee Ferry will drop below 82.5 million acre-feet (the "tripwire") by the end of Water Year 2027.  If this happens, the odds are high that the Lower Division states will trigger what they referred to in their February 13, 2025, letter to Secretary Burgum as a "compact call."  The nuance, however, is that the Colorado River Compact has no specific provision for a compact call. Under the compact, a call is just another word for interstate litigation.
