Coal creation mechanism uncovered
The mechanism behind one of the first stages of coal creation may not be what we thought it was, according to a team of researchers who found that microbes were responsible for coal formation and production of methane in these areas, which has implications for methane fuel recovery from some coal fields.

'Eggshell planets' are probably not right for life
Strange "eggshell planets" are among the rich variety of exoplanets possible, according to a new study. These rocky worlds have an ultra-thin outer brittle layer and little to no topography. Such worlds are unlikely to have plate tectonics, raising questions as to their habitability. Only a small subset of extrasolar planets are likely eggshell planets. At least three such worlds found during pre

Record-breaking rainfall in Asia prompts special curated journal issue
With impacts of climate change like the extreme heatwaves in Canada and Italy and the severe floods in Europe and China, 2021 has been a year of new records and fear for the future. For large parts of eastern Asia, however, the previous summer was one that locals won't forget for many, many years. For vast parts of the region, it was the wettest summer for almost 60 years, with widespread flooding

Researchers observe Marcus inverted region of charge transfer from low-dimensional semiconductor materials
Charge transfer is a key step in photosynthesis, biological signal transduction, and conversion of various energy sources. The theoretical framework for charge transfer was established by Rudolph Marcus in the 1950s. It predicts the existence of a so-called "Marcus inverted region," where the transfer rate decreases with increasing reaction exothermicity (or driving force).

Finnish parents want assessment that supports and motivates learning
In Finland, parents often regard assessment carried out in schools primarily as a tool for supporting pupils' learning and growth. However, many parents would also like to see more of numerical assessment, a new study from the University of Eastern Finland shows.

A USB-C Hub with a Display? Why it Might Be the Perfect Thing
Until recently, I've thought of a USB hub as a pretty simple piece of gear. Sure, some are powered and some aren't, and of course there are USB 3.0 versions, with some USB 2.0 versions still floating around, but for the most part they've traditionally been pretty boring. That has all changed now with the introduction of USB-C hubs that can handle high-resolution monitors along with high-speed per

Tectonic influence on Cenozoic mammal richness
Speciation and sedimentation are driven by tectonic activity, which causes fossil and rock records to share common patterns through time.
