Check out our new paper in Science Advances!
🧪🔭🪐
We show that Vesta’s giant equatorial troughs—Divalia Fossae—likely formed from spin axis reorientation and despinning as a long-term consequence of the two massive impacts near the south poles. 🪨⚒️

Reorientation and despinning of 4 Vesta formed the Divalia Fossae
The Divalia Fossae are formed by tectonic stresses from reorientation and despinning of Vesta caused by large impacts.

Holy fucking shit this is a *real* image from a *real* (presumably peer-reviewed) paper in [Nature] Scientific Reports.

How many people had to sign off on this figure?

The editor, one hopes, the reviewer(s)? The copy editor?

What had to happen for THIS to get published?
Hey @nature.com, have you got an explanation for how the hell THIS happened? & especially why you accepted a paper with such a bizarre piece of genAI slop in it?!
& more to the point, why we should take you seriously at all going forward?

Resident reported workers smoking on-site, the use of Styrofoam, and non–fireproof nets being installed in the recent renovation. The government did nothing after the complaints, and the ‘patriot-only’ elected council members even claimed the residents were the problem.

For those of you following of the tragedy at Wang Fuk Court in Hong Kong yesterday/today. Firstly my condolences to all the victims. Secondly a lot of Western media is blaming the bamboo scaffolding for spreading the fire when it is actually the flammable substandard netting....

Beautiful mineral. The name comes from Greek for 'bad guest' because its presence in iron ore would ruin the quality of the iron.

#TrilobiteTuesday

Here is part of the body of quite a large trilobite known as Paradoxides spinosus. This specimen comes from the Middle Cambrian (Drumian) Jince Formation from the Czech Republic. Paradoxides is one of the largest trilobites known from the Cambrian period.

"Ask detailed research questions to find relevant papers"

None of these are detailed. None of these are actual research questions.

Have you ever wanted to post a summary of a paper you published, post an announcement for the entire #PlanetaryScience community, or write a blog? If so, you probably realized that there are few good solutions for our community.

The Planetary Research Blog aims to fill this void.

Abstracts submitted to LPSC 2026 are required to comply with White House (non-legally binding) executive orders forbidding mention of topics related to diversity, equity, and inclusion.

At least USRA/LPI isn't hiding it.

But is this what our community wants? Or deserves? I don't think so.
