Explored a bit of the French Quarter during a lunch break at #AGU25

First day at #AGU25 !

Geologist here! Yep, this is likely quartz and/or calcite that formed in vugs/cracks in the rock. When minerals are dissolved in groundwater they can deposit in voids like this when they move through the rock over time!

Every machine in a Hospital that diagnoses your body without cutting you open is based on a principle of Physics, discovered by a Physicist who had no interest in Medicine.

If you think the world doesn’t need Basic Science, or that somehow Science has failed you, think again.

Here's some of the impact cratering in action! ☄️

#Purdue #PhysicsInsideOut #Outreach

A professor presents some photos of different types of meteorites to a classroom. The students are sitting in burgundy-colored office chairs.

A close-up of an iron meteorite exhibiting an arrangement of interlocking metalling crystals, called a Widmanstatten pattern.

A jar with iron filings in oil forming a magnetic dipole. A tube goes through the center of the jar where a magnet can be dropped in. This allows students to visualize magnetic field lines in 3D.

Students drop rocks into boxes with flour and cocoa powder to simulate impact cratering. The boxes are placed on a black tarp.

We had so much fun teaching students about meteorites, planetary magnetic fields, and impact cratering today! #Purdue #PhysicsInsideOut #Outreach

A pair of azure butterflies on the trail floor. They have whitish gray wings with dark speckles, large dark eyes, fuzzy legs, and striped antennae.

A skink in the leaves along the trail. It has a brassy brown color and a dark orange head, blending in with the surrounding leaves.

Plus some fuzzy and scaly friends 🦋🦎

A river running through the center of the image. On the sides are sandy banks lined with trees and some rocks outcropping.

A person standing in a small canyon cutting through some sandstone. Trees are growing on top of the stone and the sunlight is poking through the trees.

Another small canyon cutting through sandstone lined with moss and trees. A log lays across the floor of the canyon which has some water trickling across its surface. A blue lens flare cuts across the lower part of the image.

A canyon with a stone bridge crossing the top. The sides are lined with moss and trees and there is some water along the left edge of the canyon.

Explored some more of Indiana's hiking trails today ☺️

The president's budget request for NSF FY26 is also out. It zeroes out the NSF astronomy & astrophysics and NSF MPS ASCEND postdoc fellowships. nsf-gov-resources.nsf.gov/files/00-NSF...

"Imagine the auto industry without 3D printing. NSF funded that. Artificial intelligence? NSF. MRI machines that help doctors diagnose you? NSF. Doppler radar technology that makes aviation safer by conquering wind shear? NSF. Duolingo‘s underlying programming? NSF. The internet itself? NSF."

A dark slate path leads through an arboretum surrounded by lush plants and trees.

Conservatory in the arboretum. In the center is a shallow pond and to the sides are paths surrounded by green shrubs and purple flowers. Along the back wall is a door with symmetrical hedges on each side.

A path in the arboretum leading up to a circular fountain. Tropical plants surround the path.

Sunlight pokes through the arboretum, shining through tropical palms.

The arboretum at Como Zoo was also fantastic!

So excited to be visiting the IRM at University of Minnesota to do some lab work! 🧲🔬

Congratulations! 🎉

NSF Grant Termination Information Collection Form Please use this form to submit information identifying specific NSF grants that have been cancelled for any reason after January 20, 2025. We are tracking these grants to increase transparency, organize affected PIs, and facilitate responses, including via litigation. Please share the form as widely as possible with your networks. We are actively building a pipeline to organize these terminations and will soon have a tracker akin to our NIH grant tracker at https://airtable.com/appjhyo9NTvJLocRy/shrNto1NNp9eJlgpA WE WILL NOT DISCLOSE THE IDENTITY OF ANYONE WHO USES THIS FORM TO PROVIDE INFORMATION. We will keep your identity confidential. These resources are maintained by Noam Ross of rOpenSci and Scott Delaney of the Harvard T.H. Chan School of Public Health, with input and support from additional volunteers. For any questions, please contact Scott Delaney on Signal (sdelaney.84). THANK YOU FOR YOUR ASSISTANCE!

🚨Report your NSF grant terminations! 🚨

We are starting to collect information on NSF grant terminations to create a shared resource as we have for NIH. The more information we collect, the more we can organize, advocate, and fight back! Please share widely!

Adenomyosis, the 'silent illness' plaguing their lives, goes undiagnosed for decades This 'silent disease' plagued these women's lives for decades. One woman lost her dream job. For another, the diagnosis came after her hysterectomy.

I’m so glad USA Today covered adenomyosis. I struggled with this “silent disease” for decades. It caused my infertility and because I had go on hormonal birth control (which contributed to my DVTs) it nearly killed me. We need better treatments, even as Trump/DOGE is killing uterine health research.

I received this news on Monday but was hesitant to share due to everything that is going on. In the end, I figured it was good to let bsky peeps know that new grants are still getting funded!

To our many American friends. The National Academies have assembled a package of resources for researchers facing threats or attacks in the US

I'm early-career and always have been unsure what to do in this case. If somebody signs their review is it a green light to name them in the acknowledgements?
