Possibly one of the most amazing fossils to ever come out of the Fossil Butte Member of the Green River Formation in the US, this is a fossil of a Apatemys chardini - a lemur like mammal from the Oligocene. This is the best and most complete example of this species - in a private collection.

My* mindat paper is published in American Mineralogist! I feel almost like a real scientist. Now I need to beg for views and citations like some kind of Youtube influencer. Yay. pubs.geoscienceworld.org/msa/ammin/ar... * Other co-authors may exist.

Antique stall in Tirana, Albania. No translation necessary

And I'm now in Albania, a place I've always wanted to visit. Enjoying it thoroughly.

Melanterite stalactite, from the 10th level of the Trepça mine in Kosovo. Amazing visit yesterday.

Have obtained these two specimens for my good friend Kerry, who needs them for reasons

This image is a humorous and scientific reinterpretation of Maslow's Hierarchy of Needs, comparing human needs to the Igneous QAPF rock classification. The pyramid is divided into five layers, labeled from bottom to top:

Physiological needs (red): Includes "food, water, warmth, rest," representing the fundamental human requirements.
Safety needs (orange): Refers to "security, safety," emphasizing stability and protection.
Belongingness & love needs (green): Highlights "intimate relationships, friends," which symbolize social connections.
Granite (blue): Subdivided into "syeno- and monzo-granite, granodiorite, tonalite," humorously comparing human psychological needs to various granite compositions.
Quartz-rich Granitoids (purple): Defined as "might not be igneous," reflecting the highest level of need in the context of "Quartz-rich needs."

I look after a large list of holes.

Vibe for 2025

One of these tedious word grids with all sorts of phrases that are meant to bring positivity, such as POWERFUL and OPTIMISM "hidden" within, except on this EAT and ROX are outlined in red.

Everything on one chart. Mass vs Radius. Lineweaver, Charles H., Patel, Vihan M. (2023) All objects and some questions. American Journal of Physics, 91 (10). 819-825 doi:10.1119/5.0150209 pubs.aip.org/aapt/ajp/art...

A logarithmic plot visualizing mass versus physical radius, with various regions and phenomena labeled. The x-axis shows the log of physical radius (in centimeters, with equivalent Mpc at the top), ranging from the Planck length to the Hubble radius. The y-axis shows the log of mass (in grams, with equivalent energy in GeV at the right), spanning subatomic particles to galaxy clusters.

Regions include:

"Quantum uncertainty" at small radii and low masses, where quantum mechanics dominates.
"Forbidden by gravity," where gravity limits dense configurations like black holes.
"Sub-Planckian unknown," below Planck length and mass.
Labels for objects from fundamental particles (H+ and atoms) to humans, Earth, stars, and galaxies.
Stellar remnants (white dwarfs, neutron stars, black holes) and cosmological scales (Hubble radius, galaxy clusters).
Overlays indicating the dominant cosmological parameters (ΩΛ, Ωr, Ωm) in shaded colors. Key milestones, like the Sun, Earth, and Planck units, are marked for reference.

A humorous comic strip with three panels. In the first panel, a woman wearing a wide-brimmed hat and leopard print is selling crystals at a booth labeled "Gemma's Crystals." She holds up a red crystal and says to a potential customer, "This one protects you from being run over." The second panel shows the customer responding with "Cool. Can I see that?" as they take the crystal. In the third panel, the seller is being hit by a car while the customer looks at the crystal in her hand with a neutral expression. The car crash scene includes broken table pieces and scattered items from the booth. The comic is signed "@Beetlemoses."

That, kids, is how you do a headline.

The image shows a CNN Science article headline that reads, "Could mouse sperm orbiting Earth be the future of humanity?"

So I was given this old trophy that had a rock on it, and turns out it's a piece of "platinum-rich"* ore from the Merensky Reef, South Africa. Some nice visible chromite and sulfides (pentlandite/pyrrhotite?) along with the usual silicate gunk. * Everything is relative.
