Square photo taken looking down at a cluster of bright yellow autumn crocus flowers. What can be seen of the ground looks gritty, rather than fertile.

I thought yellow crocuses were spring flowers, but this picture was taken in Middle England recently.

As writers, it's important to remember that if we don't pay attention, we miss the reality of what's actually happening in the now and end up thinking in clichés.

Cartoon titled "Earth’s first science fair" showing three cavemen presenting inventions: a “pointy stik,” “fire,” and a “weel.” A judge gives third place to the stick, second to fire, and first place to the wheel, while the cavemen stand proudly behind their creations.

A black-and-white photograph of a rugged rocky coastline with ocean waves breaking against the dark, textured rocks under a cloudy sky. The soft light and fine grain give the image a classic film aesthetic. Captured on Ilford HP5+ film with a Minox 35GT-E and its 35mm f/2.8 Color-Minotar lens, developed in Rodinal 1:25 for strong contrast and defined texture.

This evening, President Trump is ordering 400 members of the Texas National Guard for deployments to Illinois, Oregon, and other locations within the United States. No officials from the federal government called me directly to discuss or coordinate.
We must now start calling this what it is: Trump's Invasion. It started with federal agents, it will soon include deploying federalized members of the Illinois National Guard against our wishes, and it will now involve sending in another state's military troops.
I call on Governor Abbott to immediately withdraw any support for this decision and refuse to coordinate. There is no reason a President should send military troops into a sovereign state without their knowledge, consent, or cooperation.
The brave men and women who serve in our national guards must not be used as political props. This is a moment where every American must speak up and help stop this madness.

Four of a family of coyotes stand in the golden light of the morning sun along a rocky, shore against an wall of fallen limestone cliffs. The coyote in the middle is staring off into the distance while two other feed on the remains of fish. The fourth coyote is looking over the shoulder of the one on the right, hoping to get a taste.

A few more photos from my morning with the coyotes from my kayak. The sun had cleared the horizon at this point and the fish left by the commercial fishermen were running out, leading to some scuffles among family members. #mammals 🌿

Pretty clear Stephen Miller, Noem, Hegseth and Trump are trying to provoke a Civil War at this point. What's interesting is they want to do it now, because even though they're unpopular, they seem to believe this is the most popular they'll be ever again. We can't let them win.

Seconded. Any satellite in a polar inclined mapping (and many other variations) orbit will pass over Ukraine a few times a day. China could be supplying surveillance, but unless you can somehow detect maybe slewing to image Ukraine, you don’t know. That said, it wouldn’t be shocking (🤬).

Gaia data shows a massive wave rippling up and down through the Milky Way’s disk. It displaces stars hundreds of light years above and below the galactic plane and stretches across tens of thousands of light years.
