Just in case you've seen climate sceptics posting highly misleading charts on social media about wildfires, here's our new factcheck...
NEW – Factcheck: No, Europe is not having its ‘quietest’ year for wildfires ✍️ @giulianaviglione.bsky.social and @rtmcswee.carbonbrief.org 💬 With comments from @calxcunningham.bsky.social Read here: buff.ly/pDQGTR3
New from James: how fire danger is changing across Europe 🧪
Fire suppression in Europe has led to an overall decline in wildfire since the 80s, despite a global warming-fueled rise in risky fire weather. That can't last. "This is the kind of trend that is unstoppable." New in @nature.com:🧪 www.nature.com/articles/d41...
The mission to rescue the Swift Observatory is experiencing technical problems. They may be solvable, but it's a nail-biter. Unclear if the observatory will survive. 🧪🔭 arstechnica.com/space/2026/0...
NASA & Katalyst Space are attempting to rescue the Neil Gehrels Swift Observatory, a powerful gamma-ray telescope that's on a death-spiral toward Earth. A booster spacecraft, called Link, is now on its way. It will attempt to grab Swift & lift it to safety. 🧪🔭 spacenews.com/pegasus-laun...
I went to college, I even went to MIT, but I'm damned if I can solve a captcha on the first try
Firefighters in Oregon, Spain, and now France (?!) are battling wildfires big enough to generate pyrocumulonimbus clouds. These fire storms are treacherous on the ground. But scientists are concerned about the *planetary* consequences of injecting so much smoke into the upper atmosphere...🌍🔥🧵

NIH grants have been under political scrutiny since early 2025. But what does the screening process actually look like? What is being flagged? I spent a month digging into leaked docs and emails. We've published the 235-word list that are being flagged by an internal AI tool. And so much more. 🧵
Inside the new political screening that’s stalling NIH grants
Mandatory reviews by top health officials and checks for 235 disfavoured terms have left hundreds of vetted grant applications in administrative limbo.
