Yes. This is increasingly a problem. Partly an issue of convention center cost, I would suspect, but it would be interesting to learn how different societies view this.
Conference registration fees are getting out of hand. I know its part of the tenure game but I can't justify dropping 800 USD to go give a talk.

Great little crystal of bright orange scheelite. It would be surprisingly heavy if you held it due to the tungsten in this mineral. #MineralMonday #GeoscienceBluesky ⚒️🧪

The talks were remarkable, as were the tutorials. HUGE thanks to all speakers and tutors!

As far as the masked individuals in unmarked cars (my first post): I have not met them. But I have seen some videos from Durham, North Carolina, my home town. So this is close enough for me to comment. As I said, my firm view is that this needs to stop.
The point is that this practice of sowing fear needs to stop.
Now. I am actually a citizen. But because of Justice Kavanaugh's words, technically I can be profiled. And no, the current profiling, as reported, does not appear to target me. But that does not make things better.

I have never lived in an America where immigrants needed to be afraid to be rounded up by masked individuals in unmarked cars according to their looks and their accents. I am not likely to be profiled. I think. But I carry my passport, as I always have.

Happy to be part of this new paper today, with a pretty cool effect ... at room temperature, if one excited this material with circularly polarized light, the electrons/holes in the material "remember" for quite some time, as seen in subsequent emission.

Thermally Activated Circularly Polarized Photoluminescence in a 2D Hybrid Perovskite with Giant Spin Splitting
We demonstrate large circularly polarized emission in polar achiral 2D halide perovskites excited with circular polarization. This thermally activated ‘spin memory’ reaches 19% polarization at 350 K,....

I wonder if I should post more routinely that we do have monthly video meetings for anyone in the @fhi-aims.bsky.social community.
The next one is tomorrow, Nov 12, 8:30 am EST. Time and coordinates are routinely posted in the Slack workspace.

In other news, my (routine) eye exam improved my outlook so much, this evening. Rainbows everywhere. (Each light source. Aka dilated pupils, following the exam.) And happy to confirm that green light is only a single spectral line, white light a broad spectrum. No need for a prism tonight.

Good reminder. Important in science.
Comparison is the thief of joy.
When you know who you are, what you value and work towards, you realize it is not necessary.
This mindset gives you the peace&space to sincerely cheer for other people. Because they are in their lane. Not yours.
