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.

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.

Roughness maps push Mercury's total contraction up by 10 to 30 percent

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.
