I think each of us in academia knows people in our departments or fields who are horrible people and also know whoโ€™s protecting them. These revelations should not be a surprise to any of us.

I'll share this again for 2026 and for any new influx--well over 100 planetary scientists here on Bluesky.

Given <waves hands around> they may not necessarily be posting much about planetary science, but that's how it goes.

If you're a planetary scientist and want to be on the list, DM me!

If you are organizing a #PlanetaryScience meeting, there is no reason to pay for a service to manage abstract submissions, registrations, and program management. We are offering the use of our Indico server to the planetary science community for free.

Great news ๐ŸŸข๐ŸŸก๐Ÿš‡ customers! Starting 12/31 @wmata.com is extending every other Yellow Line train to Greenbelt. That means more MD-DC-VA direct service & north of Mt Vernon Sq will have 4 min peak/6 min off peak service frequency. Continually improving Americaโ€™s Metro System.

We have 526 scientists signed up for spring semester. We try to get that to about 1000 scientists before unleashing the teachers on the database. Wanna connect a class of kids with science this spring? Sign up!

Hi Internet! I'm Drew and THIS IS MY FACE.

If this GIF has ever brought you joy in the past, I humbly ask you to consider making a donation to the National MS Society. It would mean a lot to me and to those I know affected by the disease!

A black graph with white text. Y-axis is Average time; X-axis is number of required integration steps. There are several dots showing the performance of CyRK's cysolve_ivp, pysolve_ivp, and nbsolve_ivp functions compared to SciPy's solve_ivp. In all cases CyRK is significantly faster than SciPy. The plot shows the cysolve_ivp method to be the best in all circumstances.

I wanted to share a side project I have been working on: CyRK github.com/jrenaud90/CyRK a #Python package that mimics much of the functionality of #SciPy solve_ivp but can perform #ODE integrations 100's x faster. If you are looking for a numerical integrator for your python project, check it out!
