Keep sciencing. We are living through a time when looking at a rock and wondering how old it is qualifies as an act of resistance.

The same exact thing happened to me yesterday hahaha 😂 I didn’t realize until I scrolled to the very bottom of the page

🎂 Happy birthday, #MarieTharp! 🗺️ A pioneering geologist and cartographer, Tharp created some of the world's first maps of the ocean floor, and helped prove the theory of plate tectonics. Her legacy reverberates across ocean sciences today. Learn more: lamont.columbia.edu/news/happy-b...

The curly girl Reddit community helped me immensely when I got started. I would recommend getting a razor cut (they cut your hair w a razor blade so each curl is defined) but not a devacut (devacuts were too expensive and didn’t work for my 2b curly hair). Deep condition w clarifying wash 1x/month!

This Crowned Aeolis (Facelina auriculata) photo is special for more than just its striking blue colors — it's also among the first iNaturalist observations of the species in Canada.

A comic about Karl Poppers paradox of tolerance using nazis as an example. If we extend tolerance to the intolerant, the tolerant will eventually cease to exist.

Karl Poppers paradox of tolerance needs to be spread far and wide. Unfortunately, we may be too late. I really hope we aren’t.

That’s a great idea- I will do that from now on. Thanks!

This is unfortunate - I made my AGU 23 presentation on a Mac and during my talk it had the incorrect formatting (no gridlines, different plot backgrounds, etc) and it really threw me off. It was fine in the pre-presentation screening though, so it was a big surprise. Maybe this is for the best?

Conference poster titled “Paired zircon and allanite dating of late Pleistocene-Holocene Rhyolites in the Mono Basin, Eastern California, USA”. The poster displays a geologic map, a backscattered electron image of allanite, fayalite, and magnetite grains, a whole-rock geochemical plot, U/Th isochrons, and an age summary plot showing how our method greatly increased precision compared to previous methods.

I couldn’t come in person to present my #IAVCEI2025 poster, so here it is for you all to enjoy!

Nine reduced rhyolites erupted in quick succession in the Mono Basin (Eastern California, just north of the Long Valley Caldera) ~6,000 years ago!

I stumbled upon the synchronous fireflies while backpacking in the smokies and staying at a site close ish to elkmont. I can look and see what my itinerary likely was (this was back in 2018) if you are interested in backcountry fireflies in the smokies!

Square linocut print on white paper of seismologist Inge Lehmann in a fur coat, silk scarf and dapper hat, in dark grey-teal ink overprinted with her diagram of the cross-section of the Earth in orange and red from her P’ paper, showing the mantle, outer core and inner core, an earthquake epicentre marker E and labelled ray paths through the Earth.

Happy birthday to Danish #seismologist Inge Lehmann (1888 – 1993) who demonstrated that the Earth’s core is not a single molten sphere, but contained an inner solid core, in ‘36. She was a pioneer #womanInScience, a brilliant seismologist & lived to be 105.⁠ 🧪🐡⚒️ #histsci

This is disrespectful and a flat out lie that further stigmatizes autism. It’s not a virus or a disease - it’s a neurological condition with a wide spectrum. Many Americans with autism work, pay taxes, and are living happy and healthy lives.

A few scenes (with unusually clear sound due to absence of wind) of the Strombolian activity at #Etna's Southeast Crater during the night of 2-3 April 2025. Note the cute little secondary vent in the latter part of the video.

Here’s a video with a nice hawk gracing me with its presence. If you know what type of hawk this is, please let me know!

Another beautiful ocean view with some weathered granite cliffs.

YouTube video by Senator Chris Murphy Murphy: Six Weeks In, This White House Is On Its Way To Being The Most Corrupt In U.S. History

A rare example of #DemsDoingSomething: Senator Chris Murphy laying out the first six weeks of the current regime’s corrupt behaviors on the Senate floor. Worth the watch. www.youtube.com/watch?v=hyco...

Some examples of research USGS does that is at risk with RIFs and restructuring:
- earth quake and volcano monitoring and warnings
- landslide risk assessments
- water quality testing
- wildlife conservation
- wildfire prevention and post-fire rehabilitation
- invasive species tracking

Trump’s Cuts Come With Risks. Including From Volcanoes. (Gift Article) A spending freeze could disrupt systems that warn communities when eruptions appear imminent.

US volcanoes pose a very real threat to communities and aircraft. Cutting funds will significantly compromise our ability monitor them and mitigate disaster. Why this administration wants us flying blind in volcano territory is an utter mystery. This is not a FAFO situation.

Quote with a picture you took at a national park.

I am not a federal employee, but many of my colleagues are. The work they do to better understand + inform the public on volcanic hazards is deeply important. We are a team. The attacks on education and NSF harms our shared mission. There is no public sector equivalent for the operational work we do
