Cambridge and Berlin researchers mapped 97-million-year-old magnetofossils in 3D, finding structures suited to sensing Earth's field direction and strength. The maker is unidentified, so the navigation claim rests on inferring behavior from magnetic structure.
Reality
Osaka's ground is rising about 4 millimetres a year on average, and up to 12 in places, after Japan's early-1960s curbs on groundwater pumping. At that average pace, regaining the 2 metres or more some districts sank would take at least 500 years.
Reality
Perseverance's SuperCam survey of more than 185 targets shows Jezero's Margin Unit is magma-formed olivine rock that met water at least three times. Groundwater and later hot fluids joined the crater lake in reworking it, so its carbonate is a harder record to read.
Reality
Stefano Lorito's INGV team finds the 2025 Kamchatka tsunami began with a tenth to a fifth of the 1952 tsunami's energy, partly because most slip was deep. Shallow slip at the trench still drove a surge of nearly 20 meters onto nearby coasts, a split the first magnitude estimate cannot reveal.
Reality
Arizona State-led researchers built a plankton food-chain index that explains Bermuda's spiny lobster catch rates better than four simpler predictors. Officials at Bermuda's environment department say it can warn them of trouble in the larval stage before the catch shows it.
Reality
University of Florence geologists link quakes along nearly all of the 1,200-km Apennines to a front where deep crust peels into the mantle. One moving front would account for both the stretching and the squeezing, and for where Italy's quakes are likely to strike.
Reality
Researchers modelling the G20's Osaka Blue Ocean goal find halting new inputs by 2050 leaves microplastics at 58.4% of accumulated plastic without cleanup. Earlier cleanup of legacy debris leaves less behind but costs up to 3.4 billion euros a year, against 1.0 billion for a delayed start.
Reality
Orbiters read the carbonate at Jezero's margin as lake chemistry; Perseverance found volcanic rock that water altered at least three times, in a sequence the team can order but cannot date.
Reality
Stefano Tavani's group combined Italy's earthquake record with GPS and satellite ground motion to argue that the lower crust beneath the Apennines is peeling away and sinking, a late-stage process he calls unzipping.
Reality
Drones, satellite elevation models, boreholes and geophysical profiles put zones of broken rock beneath trenches up to 20 kilometres long, and the authors say the same signature could find caves on other planets.
Reality
Mapping, geophysical surveys and sediment analysis link shallow trenches up to 20 kilometres long to caves collapsing beneath them. The authors offer the faint surface sag as a way to find voids in other dry landscapes, Mars included.
Reality
Gabriele Russo's team re-read fossils excavated in Lebanon more than a century ago, dating Ras el-Kelb to about 400,000 years and Nahr Ibrahim to about 250,000, and finding forests unlike the southern Levant's.
Reality
A Lancaster-led study of 1981 to 2023 finds extreme dry-season heat rising at least 0.75 C a decade across a tenth of the Amazon, with the fastest growth in the central north, a region that average-temperature trends had ranked behind the south.
Reality
A Landsat-based method estimates tides every 100 metres of Pacific coastline. Inside a single 90 km New Zealand bay it finds gradients that gauge-fed models cannot see.
Reality
A decade-long, high-resolution simulation from Helmholtz-Zentrum Hereon attaches a regional-climate externality to a build-out that siting and permitting still treat as impact-free.
Reality
A mesocosm experiment found that 4 degrees Celsius of warming cut the hard-to-degrade share of seagrass dissolved organic carbon by about 28 percent on average.
