„H5N1 weitet sein Wirtsspektrum ziemlich dramatisch aus, und dabei nimmt es Mutationen auf, die das #Virus in Säugetieren besser funktionieren lassen“, sagte Worobey. Mit dieser gewissen Vor-Anpassung an Säugetiere steige das Risiko für den Menschen. So begännen Pandemien."

On 23 March, the Earth's orbit will cross the plane of the rings, making the majestic rings appear edge-on from our perspective. Since Saturn will be positioned very close to the Sun in the sky, it won’t be possible to observe it as the Earth crosses the plane. The rings will then become visible again in September this year.

That said, if you’re ready for a clear-eyed look at how bad things really are now — and how bad the people who run things truly are — then I suggest reading the full linked essay.
Here are a few excerpts...
___________________________
The rich keep getting richer. That much is clear. But what’s often left unsaid is how they’re doing it — not just through the usual exploitation, but by actively steering the world toward catastrophe while shielding themselves from the fallout.
Let’s cut through the noise: the ultra-wealthy are not just accumulating wealth; they are hoarding it, stockpiling fortunes at a rate so obscene it makes the concept of money itself feel ridiculous. While the rest of us get lectured on cutting back — drive less, eat less meat, recycle, make do with less — they are securing their bunkers, buying up remote islands, and building escape plans for the very collapse they are accelerating.
And make no mistake, collapse is not just some distant dystopian fantasy. We are already deep into a polycrisis — climate change, biodiversity loss, resource overshoot, economic instability, and authoritarian creep all feeding into one another like an unstoppable chain reaction. Meanwhile, banks and corporations, who could be funding solutions, are instead dragging their feet or outright obstructing progress, ensuring the system remains tilted in favor of those who already have everything.
If the world’s biggest banks truly cared about avoiding collapse, they’d be moving mountains right now to fund large-scale climate infrastructure. But they’re not.
And that’s not a mistake — it’s a choice.
They have run the numbers. They know full well that unchecked climate change will devastate the poorest and most vulnerable long before it affects the ultra-wealthy. So, from their perspective, dragging their feet isn’t just about short-term profits — it’s about preserving a system that ensures their continued dominance, even as the world burns.
Meanwhile, the rest of us are left watching as climate disasters pile up — floods swallowing cities, heatwaves killing thousands, wildfires turning landscapes to ash — while the financial elite sit back and continue cashing in.
At this point, it’s not just negligence. It’s premeditated collapse.
. . .
If you’ve made it this far, you already know the truth: this isn’t capitalism failing. It’s capitalism succeeding exactly as intended.
The rich are not scrambling to prevent collapse. They welcome it — because they know they’ll be the only ones left standing. While the rest of us are told to “sacrifice” and “tighten our belts,” billionaires are building bunkers, buying private islands, and hoarding resources for the dystopia they see coming.
And why shouldn’t they? They built this system to ensure that, when it all falls apart, they’d be untouchable.
Because their goal is not to fix the system. Their goal is to extract as much as possible, as fast as possible, before everything comes crashing down.

Every week on this day I turn my focus toward the most important topic of all. Because if we are to have any hope of maintaining some semblance of a healthy human society going forward, our world must quickly and decisively commit to #degrowth.
We're talking real solutions here! Real answers to the many systemic problems that plague us and threaten our very extinction.
Now, I know how unlikely it is that these solutions will be adopted by our present leadership. And I know how challenging they will be to achieve. I'm under no illusion that any of this will be easy.
But — if we don't know where we want to go, we'll never get there.
So today, I'll provide two resources for learning about degrowth. The first is simpler and more basic, while also offering a more hopeful and positive outlook. The second is a darker vision, presenting additional detail about the daunting challenges we face and the many hard steps that lie ahead of us. I hope you'll read both, or I hope you'll read at least one of them.
That's my intro. 🧵1/3 The next two parts will follow soon...

“‘I learned with concern that a French researcher,’ on a mission for the National Centre for Scientific Research (CNRS), ‘who was going to a conference near Houston was banned from entering American territory before being expelled,’ said the Minister of Higher Education and Research, Philippe Baptiste, in a statement sent to Agence France-Presse (AFP). ‘This measure was allegedly taken by the American authorities because this researcher's phone contained exchanges with colleagues and friendly relationships in which he expressed a personal opinion on the Trump administration's research policy,’ he added.”
