5. The right-wing enthusiasm for AI science is not about doing better science faster. It’s about eliminating one of the most effective forms of societal resistance to authoritarian control.

Bezos plans to sell ~$4.8 billion of Amazon stock. That's only 2.5% of his holdings in the company. That sale roughly equals the proposed ~50% cut to NSF. IOW, with modest endowment-level growth of Amazon, Bezos could fund the entire NSF shortfall into perpetuity. www.cnbc.com/2025/05/02/j...

Of course, the answer was then -and still is- a plain "no". But did all these catastrophic headlines actually help elephants in any way? Is fear and anxiety what we want to embrace in conservation? I don't think we've made any major progress on this during the past 10 yr theweek.com/articles/460...

#OTD 250 years ago, James Cook named the New Year Port in Isla de los Estados (Staten Island) and the New Year Island (nowadays Isla Observatorio). Here he collected the type specimen of several birds, including the Magellanic Penguin, the Striated Caracara and the Upland Goose.

Striated caracaras would regularly enter Magellanic penguin burrows to scavenge dead chicks. We're trying to quantify this small-sized carrion input to see how important this behavior may be, as some individuals seem highly specialized—systematically checking burrows for failed nests

🧵⏬ Ever wondered what's happening below snow in high mountains? Well, it's not at all bad down there. This is average February soil T (coldest month). Note that apart from elevation, it's mostly controlled by curvature, thereby snow depth and related insulation. Whites are temperatures above 0°C.

The first step in seriously opposing for-profit publishers is to realize that most publishers are for-profit, and most things short of diamond OA are unethical. It doesn't mean that we are bad people for publishing there, just that there's no ethical academic publishing under capitalism.

We need to all collectively decide to stop propping up these journals (MDPI and “Frontiers In” megajournals) by lending them our credibility. Every time you submit to, review for, guest edit, or even cite (??) these journals, you lend them your hard earned credibility. Don’t do it.
