Everybody makes money out of academic authors except the authors...News.

Wiley is the latest academic publisher to reach a multi-million deal to allow access to its content to AI developers, with no opt out, let alone payment, for the authors who created that content.

Wiley set to earn $44m from AI rights deals, confirms “no opt-out" for authors

The US publisher is the latest to capitalise on deals to give tech firms access to its authors’ content to train their Large Language Models (LLMs).

Scientists May Have Finally Detected a Solid Inner Core on Mars - Eos

Seismic clues from NASA’s InSight mission suggest that Mars hides a solid inner core, and raise new questions about why the planet’s magnetic field disappeared.

The 2025 Google Earth imagery is wild. We live on such an astoundingly beautiful planet.

Namibia (-23.6551610, 15.2430470). Close-up and wider view. In wide view: a structural dome popping out to say hello. Note the different eolian sediment compositions to N and S of the stream channel.

🧪⚒️🪨

Google Earth satellite image showing a sinuous, ephemeral (currently dry), braided stream that is pale gray with trees within the channel. Red eolian sands are to the south (bottom) of the stream, whereas folded, black bedrock mantled with light brown to tan sediment lies north (top) of the stream.

A red eolian dune field to the south (bottom) of a sinuous, dark line marking a stream channel. To the north (upper half) is a desert of variagated back bedrock and light tan sediment. There is a dome popping out of the ground, looking like an eyeball, in the middle, upper 1/3 of the shot.

Last week I was co-leading a field trip in Utah, to check out some fluvial and eolian rocks. It was exhausting but fun and forced me to think more carefully than before about complex bedforms. This is a 3D model of one of the many stunning exposures of the Navajo Sandstone near Escalante 🧪⚒️

Some delicate actively growing stalactites from Ruakuri Caves, formed in Oligocene limestones. Skinny varieties are probably few decades old; the larger a few centuries. Ruakuri is the Maori name for Two Dogs - refers to early Polynesian canines brought to NZ. On a visit w a couple of grandkids ⚒️🧪

Coralligenous de plateau of the ROV14: a) general view of the planispiral multilayered coralligenous build-ups; b) general view of the conical shape of some (light-blue arrows) of the ROV14 record; c) detail of the planispiral multilayered coralligenous build-ups; d) close-up of one build-up, with the occurrence of multi-layered concave structure, which allows also the local accumulation of sediments; e) rare occurrence of convex-shape (white arrow) build-up; f) one overturned crust (light-blue arrow) shows the heavy biogenic, mostly animal encrustation of the lower surface.

A study in Nature Climate Change shows that the ocean carbon sink unexpectedly declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics. 🌊 🧪

Unexpected decline in the ocean carbon sink under record-high sea surface temperatures in 2023 - Nature Climate Change

The ocean carbon sink strengthened in previous warm El Niño years due to reduced CO2 outgassing in the tropics. Here the authors show that the ocean carbon sink declined in 2023 despite record-high sea surface temperatures (SSTs), primarily due to SST-driven outgassing of CO2 in the subtropics.
