My quote of the day

We have managed to unite a country tearing down the barriers the regime built to divide us. Ours is a fight of a nation united against a criminal tyranny, in defense of its human rights, freedom, and democracy. That is why we have no alternative but victory

A beautiful closeup of a rock taken by the Mars Perseverance Rover using the WATSON camera this weekend on Sol 1644. The first image is under sunlight and the second is at night and under white LEDs.

Zoom in a check out those mineral grains!

I’ve never seen anything written, but that’s a great question. People are defintly into the mineral /gold prospecting shows.

Spectacular concentric zoning and twinning of large titanaugite in essexite (nepheline monzogabbro) from Lennoxtown, Scotland. Plagioclase inclusions within the phenocryst align with zoning just as proximal groundmass plagioclase align with its edge. #ThinSectionThursday 🧪⚒️

Large clinopyroxene (titanaugite) crystal takes up much of field of view. Tin plane cuts from top left to bottom right separating twins showing different interference colours. Multiple concentric zones apparent in finer oscillation of interference colours. Plagioclase and olivine groundmass surrounds the phenocryst.

This is why we fund scientists to study things like oyster slobber even if you don’t think it sounds important

⚠️ Chinese researchers have invented bone glue that mimics how oysters stick to surfaces underwater.

The adhesive can reportedly repair orthopedic fractures in 2-3 minutes, even in blood-rich environments, and is bioabsorbable.

My most recently published paper had a key wording change occur between when I submitted the draft, and when the paper was published.. had to have been AI. They did fix the issue, but wow…
