Fiber-optic array 3 km down a Utah geothermal well finds microquake stress drop steady across magnitudes
Hilary Chang's team used a 1,600-channel fiber cable in a 3 km Utah borehole to measure microquakes and found stress drop did not track magnitude. The same paper warns that the cable's own settings can skew the magnitudes behind that finding, so teams adopting the method need an independent check.

Logging that stripped residue and forest floor left soils a third below preharvest carbon after 20 years
Researchers on British Columbia's long-term logging experiment found soil carbon fell 52% in five years on plots stripped of residue and forest floor. Twenty years later those plots were still 33% below preharvest levels, so the way a stand is cut stays in its soil carbon account for decades.

AI-assisted assimilation of raw satellite radiance roughly halves aerosol model error over China
Chongzhao Zhang's team fed raw satellite radiance directly into aerosol simulations and cut prediction errors by about 50% in tests over China. A pretrained AI step makes the approach affordable, though the test scored aerosols against satellite data and left any forecast gains unmeasured.

Extreme fire weather weakens the firebreak that Alaska's young forests provide
Recently burned Alaskan forest reburns 1 to 3 orders of magnitude less often than older forest, Gaglioti and colleagues find in 1984-2020 fire data. Extreme fire weather weakens that barrier most in young stands, so a scar's value as a firebreak depends on its age and the weather.

Jha and Byrne varied the rate at which dry air mixes into convective plumes across ERA5 and CESM2, and found it significantly moves moist-heat extremes outside the tropics, which means a swept parameter sits underneath the wet-bulb projection.

Survey of 289 geoscientists ranks gatekeeping and sabotage as fieldwork's most damaging harms
Eighty percent of respondents reported at least one harmful interaction during fieldwork, and three quarters of the worst incidents went unreported. Severe violence and misconduct were excluded by design, which makes the headline figure a floor rather than a prevalence estimate.

An extinct Red Sea brine pool kept the metal signature of a living one
Morgan Chakraborty and colleagues sampled an active Red Sea brine pool, a depression they suspected was a dead one, and three ordinary seafloor sites. The sediments of both pools carried the same metal enrichment.

A Bayesian inversion of 60 days of pressure and velocity records from Torrey Pines State Beach separates the infragravity band and puts roughly 28% of its energy in edge waves running along the shore.

Radiative cooling and a falling Bowen ratio nearly cancel in a new global wind theory
Malte Jansen and colleagues derive the work that drives Earth's winds from two atmospheric quantities and find that warming's effects on them almost cancel, while the same simulations push storm tracks poleward.

Volatile organic compounds supply about 100 of the 460 teragrams of carbon that rain delivers each year
Ana Yanez-Serrano and colleagues estimate in a review that water-soluble VOCs account for 21.7 percent of the annual wet-deposition carbon flux, a term most atmospheric carbon budgets leave out. The figure is a synthesis assembled in a review.

Lancaster-led reanalysis redates the Exeter telegraph delay to October 1848
The railway line in the story did not open until 1846, so a team led by Lancaster University went back to timetables, newspapers and magnetic records and moved the 16-minute delay to 18 October 1848.

Radiation belt simulations matched the May 2024 dropout only when compression and outflow coincided
Xingzhi Lyu and colleagues have reconstructed how the outer Van Allen belt lost its most energetic electrons during the strongest geomagnetic storm since 2003, and the reconstruction worked only under a tight timing assumption.

Sediment traps 1,000 meters down credit cyanobacteria with two-thirds of exported carbon
A multi-year sediment-trap record from the South China Sea points most of the deep carbon flux at the ocean's smallest photosynthesizers. The authors say models of ocean carbon sequestration may need rebuilding.

Eddy covariance towers still miss the surface energy budget after four decades of use
Fluxes computed from wind and water vapor sampled 10 to 20 times a second do not sum to the energy available at the surface. Eddy covariance practitioners met at an AGU conference in 2025 to agree on what to do about it.

Mercury's lumpiest terrain carries the fewest shrinkage wrinkles, which the authors read as impact debris burying the record. Correct for that and total contraction rises to as much as 23 km, with the thermal models still to be redone.
