Margaret Hamilton empowered women and girls in science. πŸ§ͺ She made a tremendous impact on the world.

SOME do....soft bodied stuff....we're finding others eat organics in sediment....some smaller species are parasites also on larger cnidarians (anemones, etc.).

Sea spiders (species dependent) feed on soft bodied creatures....likely this Colossendeidae is looking for a snack of coral polyps! πŸ§ͺπŸŒŽπŸ¦‘πŸŒŠ AMAZING video of these adorable creatures! Thanks for sharing @tuexplorer1.bsky.social

I've kept some of these (different species, same Family) in tanks in Antarctica and NEVER seen them move that fast nor seen them drop legs like this! πŸ§ͺπŸŒŽπŸ¦‘ thanks @tuexplorer1.bsky.social for sharing this!

Interesting....as most of the specimens we've collected from Antarctica are typically robust and don't fall apart! ....and I've never seen one with ....speed?

This is a discussion point about AI (not this specific paper...but the general topic) that we should be having as professionals AND more importantly with our labs, our students, etc. πŸ§ͺ🌎🌊

"NSF’s budget, adjusted for inflation, is essentially the same as it was 20 years ago, and Tr*** wants to cut it by half next year." not ONE BIT of this is realistically feasible and it is terrifying for the future of science in the U.S. πŸ§ͺ🌎🌊

We are at a critical time for science...personalized cancer vaccines....changing climates and massive El Ninos...species discoveries....investigating/studying these is not possible in the U.S. without a well supported and robust NSF. This trend cannot continue. πŸ§ͺ🌎🌊🌱

From the article: www.nature.com/articles/d41... I believe this figure is the most disturbing....we need to value science in the U.S., and we seemingly don't anymore. The world is not going to wait. We are falling behind and the next generation of scientists is going to suffer from this. πŸ§ͺ🌎🧬🌊🌱
