A Nobelist on the Nature Effect
This year Randy Schekman won the Nobel Prize in Medicine. Last week he wrote a piece for the Guardian on how the "big dog" journals Cell, Nature and Science do damage to science. Most notably, he pledged that his laboratory would avoid "luxury journals" like these. What's the harm they do? As Sc ...
A Geological Advent Calendar
I was raised in a household with Advent calendars: charmingly detailed printed scenes studded with little numbered die-cut doors. Each day in December, the child would search for the door corresponding to that day and open it, to expose a tiny charming scene that was in some way relevant to the ...
Geo-Quiz of the Week: Caves
I used to be a caver—spent a fair amount of my late teens visiting wild caves. Then I moved to a place with no caves, moved again, and many years later I'm not sure I could repeat anything I used to do underground. But I still enjoy a tour of a good show cave, especially when they lay on t ...
Mindat.org Seeks Support
Anyone who looks online for deep, solid information on minerals has encountered Mindat.org, which presents more kinds of data than you can shake a rock hammer at, plus photos contributed over the years by collectors. I didn't realize that Mindat began as Jolyon Ralph's personal site 13 years ago ...
An Open-Access Anthropocene Journal
The American Geophysical Union, whose Fall Meeting I'm attending all this week, is taking the Anthropocene concept seriously. Today David Grinspoon delivered the annual Sagan Lecture on the subject, under the title "Terra Sapiens," putting some more flesh on the ideas I described 10 years ago as ...

What’s the Real Story With Clean Coal?
Coal-fired power plants are responsible for one third of all U.S. carbon dioxide emissions each year. Recently President Obama proposed a plan to combat climate change including a measure that will regulate emissions from new and existing coal-fired power plants. The plants will likely only be a ...
Antarctica – a general introduction
Bedrock map of Antarctica obtained by the BEDMAP2 project of the British Antarctic Survey By Bianca There have been quite a few articles about Antarctica by now, but none of them actually about Antarctica itself. For most people the seventh continent is isolated from everything, and that is actu ...
It's been a while since I posted but, as usual, things have been busy. I don't get pay, recognition, or much else for writing a blog - it's mostly for my own benefit and to encourage my writing. If others find it interesting or useful, that's an extra benefit! Anyway, a few da ...
Thin section porosity estimation using ImageJ ...
I have made a short video that shows how to use the free software ImageJ to estimate porosity from an image of a thin section cut from a rock sample. The video can be found here. Screen shot from video with porosity highlighted red and results window indicating 17.19% porosity.
I've been holding onto a couple of blogs that appear to be defunct, or which have officially ended. So I'm taking the following off my bloglist: A Gentleman's C - the first blog I followed regularly. Isis the Scientist - this one is officially done, not "sorta done but I'll still keep posting" ...
