Bunnies in a raft pull up next to a spaceship capsule, which has just splashed down and is floating in the open sea. Visible in the capsule, two bunnies wave at the ones in the boat.

Daily bunny no.3285 made it home safely

I don’t think I realized how traumatized I was just by viewing that and Columbia’s re-entry 😭 (I can’t imagine what their friends and family went through) I found it very hard to watch yesterday’s splashdown live. Phew, so happy it was successful

I know it’s not quite #caturday but Guinness was totally enthralled with the return of #ArtemisII. She had to high five the crew on #splashdown. #catsofbluesky #catsinspac

It’s my favourite too!

Promotional graphic from Beyond Benign for “Green Chemistry Connections.” The title “Blue Chemistry: The Way of Water” appears above the date and time, “April 15, 2026 | 12–2 PM (EDT).” Two speaker headshots are shown: Prof. Francesca Kerton of Memorial University of Newfoundland and Jost Dittkrist of the Secretariat of the Basel, Rotterdam and Stockholm Convention. MilliporeSigma and ICL are listed as sponsors. The background is a blue-to-green gradient with a network pattern.

Join #GreenChemistryConnections on April 15th from 12–2 p.m. EDT to explore how chemistry can help address water challenges like pollution, chemical waste, & resource management. 💧🌍 We're excited to hear from @chemmouse.bsky.social & Jost Dittkrist. 👉 RSVP: mailchi.mp/afdfee950c76...

Indeed, indeed.
I'm sure there are plenty of papers around that were wrongly using cameras to monitor chemical reactions. Especially with the rise of the SDL, this is an extremely important topic....
Just because you see a color, it doesn't mean that your camera can quantify it....

Beautiful!

What is road salt and how does it impact the environment? The ice-melting substance is ubiquitous in many snowy areas. Smart salting is key to minimize its environmental impact

Chloride salts are used to make roadways safe in the wintertime, despite being very environmentally unfriendly and corrosive. Research is ongoing to find new ways to limit the corrosive properties of salts and minimize the amount needed to break the ice. cen.acs.org/environment/... #chemsky 🧪

Ferrioxalate photocatalysis: A multitasking platform for reductive iron catalysis Iron’s abundance motivates its use in sustainable catalyst systems that also offer complementary reactivity manifolds compared to precious metals. However, the challenging reduction of benchmark iron ...

Great way for chemsky to kick off 2026 as @fabiojulia7.bsky.social and company repurpose the ferrioxalate system as a versatile photoredox catalyst for dehalogenation, hydrocarboxylation, and cross-coupling reactions!

Space pollution levels in the atmosphere are rocketing More metal than ever is entering the upper atmosphere because of space traffic, with unknown effects on climate

As more rockets and satellites in low Earth orbit burn up in the atmosphere at the end of their lives, the amount of introduced vapors and particulate matter there is dramatically rising. cen.acs.org/physical-che... #chemsky 🧪
