Thanks so much @cmdr-hadfield.bsky.social for sharing the @westernu.ca news story about our paper on the beneficial effects of meteorite impacts for microbes!
When asteroids slam into Earth they create a warm, wet local environment. These 3 guys dug through 78-million-year-old core samples to show how quickly life moves into the hellscape, to understand Earth history. news.westernu.ca/2025/09/life...

The less glamorous side of #fieldwork - after a promising start, we lost a drone & then the rain started. And the outcrops were, well, less than impressive! We returned soaked to the skin back to camp. But a dry sleeping bag feels like the best thing in the world 😊 #fieldwork #outdoors #camping
