Oof, same battery issue as last year's recall for 2019-2020 cars which still has no fix. Lithium deposits can form in the battery (estimated to affect 1% of cars in recall) & cause a fire when fast-charging.

Nissan LEAF hit with a big recall, more than 19,000 vehicles affected

It’s a good thing the new 2026 LEAF should be here any day. The recall affects over 19,000 Nissan LEAF vehicles, model years 2021-2022, because the battery may overheat during fast charging. Here’s the fix. more…

Drought and insects have killed an unprecedented number of Oregon’s Douglas fir trees during the last decade, costing billions in timber value, damaging infrastructure and ramping up wildfire danger.

Sometime around the turn of the 20th century, the sea mink disappeared from Maine's coastal waters. Its loss came during a rush of North American extinctions, but many today have never even heard of it.

My latest for Smithsonian:

The Life, Loss and Lore of the Sea Mink

It might be among the first mammals to go extinct in North America after colonization. But can scientists prove it was even a distinct species?

I recently spoke at a neighborhood association meeting about native plants in the city.

Going to meetings like this can reach audiences that aren't following scientists on social or reading up on their own.

If you wanna take any bits/pieces of what I said to them, handouts & slides in the thread.

I'm developing a grad course on experimental design (study design generally) & data analysis in biology. What topics, papers, etc. do you think are most important? If you teach something similar, I would love to hear what/how you teach (if you are willing to share a syllabus that would amazing!).

Immigration advocates say if you see ICE targeting someone, knowing what to do in the moment is critical to protecting immigrants. It’s hard to know what to look for, but this guide can help you better understand how to be an effective bystander in Oregon, and your legal right to do so.

What to do if you spot ICE in your community

Amid President Trump’s immigration crackdown, local community networks are the first line of defense. Here’s what Oregon advocates say you should do if you see agents detaining someone.

🌡️By the way, the excessive heat that is helping to create the high wildfire danger Tuesday -- climate change has made these unusual temperatures at least 2x to 5x more likely.

In Interior Washington, early September heat like this would be almost impossible without a fingerprint of climate change.

Analysis was "able to identify two key trait mediations that are consistent across the studied taxonomic groups. First, habitat breadth strongly mediates the effect of landscape diversity, and second, voltinism mediates the effect of temperatures."
