I think it’s fair to say that the student journalists at Cornell are braver than the news networks who just gave up on their WH pool ban even though CNN is still being denied access. www.cornellsun.com/article/2026...

EDITORIAL | Cornell Won’t, We Will
The Editorial Board demands that Cornell stops protecting the alleged Chi Phi rapists through the University's opaque sexual assault policies.

Working on my Mars slides for class, which means it's time to bring back my favorite slide I've ever made:
The "we're so back/it's so over meme" that has been edited so the x-axis is time from 1960 through 2040. The plot oscillates semi-sinusoidally between positive (we're so back) and negative (it's so over). It's labeled Mars Exploration Timeline.

The start of the timeline is small oscillations close to zero. These are labeled: first Soviet attempts (note: none of the Soviet attempts worked but they sure tried). The steep positive peak next to it, we're back, is labeled Viking landers. Then a massive negative, it's so over, is labeled: everyone crashes in the 90s. Look up Mars exploration to learn more about this. Then an even larger positive spike, we're so back, is for Curiosity and the other Mars rovers.  Then a positive/negative combined spike is labeled Mars 2020 (for various reasons). Then a last negative, it's over (real) is labeled Mars Sample Return. This is accurate.

I recently dug back out my M.S. work for some other stuff. It was rejected by a journal deservedly. But I still remember Reviewer #2 (amouyous) saying they stopped reading after page 3 because it was bad, and the Venus data were already more than 20 years old, and there was “nothing to discover.”

It's me, the mythical STEM PhD who not only took history classes but got a whole history degree! Studying history is arguably one of the most important things STEM students can do. Science isn't done in a vacuum, and students should investigate the people, places, and events that shape it.

Wtaf is this question my university just asked me about my project?
Does the project involve any work that could be interpreted as promoting DEIA, climate change research, or non-compliant to any Presidential Executive Orders?

The image is of a four panel comic.
The title reads, "Suddenly Finding A New Obsession".
In the first panel we see Sarah, the protagonist, in front of her computer. She has a bored expression on her face.
In the second panel we zoom in on her face. She looks suddenly alert.
In the third panel we zoom in even closer on her face. Her eyes and mouth are wide open in intrigue.
In the fourth panel we zoom out and see Sarah in front of her computer again, but this time she is dressed in a frog costume, surrounded by frog toys, and has an "I heart frogs" poster behind her.

This is a piece of the Moon. It's a polymict breccia, part of the lunar highlands, and was collected by the crew of Apollo 16. It's 3.9 billion years old, or about 28% the age of the observable universe.

This is a photo of Saturn and its rings. It's also a photo of Earth. See that bright point just right of centre? That's home. That's us.
The upper left is the night side of Saturn. Part of the ring system is visible at the top part of the frame. A broad, diffuse glow from the planet's E ring is visible in the lower half. There is a small, unusually bright point of light just right of the image centre.
