Heart break like that is rough. Not sure if this is going to comfort you, but you’ll be counting minutes, then hours, then days, then months, then you’ll realize you stopped thinking about them. Just keep breathing, keep moving, you’ll make it through. You’ll make it through.

It’s fun if you join the first and last sentences of the last paragraph:
“What’s exciting here is not just that a biological system can play Doom, but that it’s…much closer to the kinds of challenges future biological or hybrid computers will need to handle.” Yes, we need them to fight Mars demons.

An image of a large nebula structure that dominates the majority of the frame. There are two nebula in the structure: the Running Man, which is the smaller of the two and sits above and to the left of the larger Orion Nebula. The Orion Nebula dominates the majority of the frame. It's shape consists of a teal-blue shell surrounding a greenish-gold center. Throughout the image are swirls of background dust, which contrast subtly against the deeper background of the night sky. There are some stars dotting throughout the image, but compared to the nebula they are lost in the background.

I also processed an SHO version of the Orion Nebula. I know that HOO usually wins the show but I love how this one turned out. The blues, greens, and golds are just a wildly different view than you normally see for it and I'm here for it.

A 1944 map by geologist Harold Fisk charts a 40-mile stretch of the Mississippi River from Friars Point to Gunnison, Mississippi. Fisk used aerial photos and maps to estimate the past and then-present channels.

Rivers are living beings.

Zero surprise the folks who brought us the Iraq war are teaming up with the folks who are bringing up the Iran war.

YOU BETTER NOT UNSANCTION THOSE 🤬 TERRORISTS!!!

How TF is that an ‘easy problem’!?! He never stands up to Vlad and he’ll lie to Trump and say “that’s not true” and the 🤡 will take it as direct evidence that it didn’t happen.

Five panel close-up stitched view of a rock formation on the surface of Mars, as seen by the Curiosity rover. The formation is a light, sand color and is covered in pea-sized nodules.

#PPOD: From orbit, parts of Mars look like sprawling spiderwebs etched across the hillsides. These patterns may record a time when groundwater flowed through large fractures in the rock, leaving minerals behind. 🧪 🔭

Don’t let mega-constellation-building billionaires steal your night sky Satellites are wonders of modern technology that have improved all of our lives. But having more than a million of them in orbit could destroy our view of the heavens and seriously damage our planet

Elon Musk has already started plans to launch a million satellites.

Yes. A MILLION.

This is a colossally bad idea, and it's not too late to make your voice heard. I explain everything:

More importantly, the most COMPROMISED US government ever assembled.

We need way more of these than data centers.

I remember when A-10s were “not what Ukraine needs”, but I bet they’d make great Shahed hunters (among other things). But hey, maybe a couple squads of F-16 lying around wouldn’t hurt. Or more ATACMS. How about A NO-FLY ZONE. Then Ukraine could donate a lot more drone interceptors…just say’n. 🤩

No GeoOsInt for that war I guess…

Densely packed fossil burrows in a gray limestone that look like pipes, some branching into "Y" shapes, and with knobby (pelleted) exteriors, with circular cross-sections.

From Divine Rapture to Tech Rupture: Why Silicon Valley Supports Armageddon in the Middle East When US military commanders are telling troops that strikes on Iran fulfil biblical prophecy this is expression of an apocalyptic network connecting the Pentagon, Silicon Valley and the Kremlin

“When commanders tell troops that restraint is opposition to Christ’s return, and tech investors see government oversight of AI as Antichristic tyranny, they are reading from the same eschatological script.” By @peterjukes.bsky.social, 3/3/26 #PeteHegseth #DougWilson #PeterThiel

Things Ds can be fighting for now:
- Recommit to Europe/Ukraine, stop appeasing Putin, who is helping Iran attack US
- End the war, prevent US/global economies from going to sh*t
- Roll back the inflationary tariffs
- Rescind Trump tax cuts, ICE expansion
- Make US clean energy superpower

Satellite photos show California's sudden snowpack meltdown: Now you see it, now you don't Satellite images show the Sierra Nevada before and after a major heat wave melted significant portions of California's snow.

Now you see it, now you don't. Near the end of this extremely warm winter, California's snow is rapidly melting. My colleague @castleman.bsky.social shares some striking satellite images. He spoke with @weatherwest.bsky.social about the remarkably rapid loss of snow: www.latimes.com/california/s...

“The White House’s status as a traitor to the American people is well known and we’ll keep doing whatever crimes we want.”

A brown penguin chick of some kind. It looks very much like a man in a suit. It is bedraggled and miserable

Made it to Friday but at what cost

Even if it takes years, we have to bring EVERYONE who made this happen to justice. No moving on, no letting this go.

Revenge is good enough motivation for me personally, but the nobler and important reason is to ensure that anyone who thinks of doing this again knows they’ll rot in prison for it.

What Does Russia Have on Trump? Americans Deserve an Answer As Russia reportedly shares intelligence with Iran that could endanger American forces, the White House chooses to ease pressure on Moscow instead of confronting it.

Ukraine offers to help defend the West from Iranian drones.

Russia helps Iran track American forces.

And the White House eases sanctions on Russian oil.

Explain that to the families of U.S. troops. My latest:

New NASA DART Mission Data Reveals that Asteroids Throw ‘Cosmic Snowballs’ at Each Other | College of Computer, Mathematical, and Natural Sciences | University of Maryland Astronomers found evidence that rocks continuously travel between Didymos and its smaller moon Dimorphos, reshap

Astronomy's Jessica Sunshine and Tony Farnham discovered surprising asteroid behavior after analyzing NASA's #DARTMission data ☄️

The team found fan-shaped streaks on the asteroid moon Dimorphos' surface—the first visual evidence of rocks and dust naturally traveling between asteroids. 🔭

Nature Report, Killed by Trump, Is Released Independently

Trump cancelled the National Nature Assessment, but scientists independently released a draft report, 'Nature Record'. It warns US ecosystems are declining, with many species at risk of extinction. Restoration and policy action can still improve nature resilience.
