I got a huge amount of editing work done this morning, sitting at my cousins’ dining table. Last night they asked intelligent questions about my project, with genuine enthusiasm. That set the stage. Then this a.m., no distractions, nothing to do but write. I should get my house fumigated more often.

I’m enjoying seeing people’s moon and Venus pictures tonight. These are my iPhone snaps.

The #ColoradoRiver disappeared from the geological record for 5 million years. Scientists now know where it went — Holly Ober (University of #California Los Angeles) #COriver Dark red and green mudstone beds with tan sand-dominated layers above, marking the arrival of Colorado River sediment into the Bidahochi basin 6.6 million years ago.

Cool. Ad hoc collaborations formed to address this mystery. 🧪⚒️

The Inside Story of Five Days That Remade the Supreme Court

“Even as they debated the Obama plan’s possible burden on the power industry [… ] not a single justice [… ] mentioned the dangers of a warming planet as one of the possible harms the court should consider.”

Astonishing. One wonders how informed these justices are.

This is indeed useful for research. I knew a few of these search strategies, but not all.

Thanks! We’ve been getting spot treatments for years and regular inspections so hopefully it won’t go as far as your sister’s house. That sounds really bad.

It’s like this in my neighborhood of old houses. One friend put off termite inspections until she retired, and then there was a ton of damaged wood. The inspector told her the only reason her house was still standing was because the termites were holding hands! 😂

Foto des Pferdekopfnebels im Sternbild Orion, aufgenommen mit einer gekühlten Astrokamera durch ein Teleskop Celestron C8. Zu sehen ist ein rötlicher Nebelstreifen von links oben (=Norden) nach rechts unten (=Süden), vor dem sich eine scharf begrenzte Dunkelwolke abzeichnet, die an die Form eines Pferdekopfes erinnert. Unten links ist zudem ein blauweißer Reflexionsnebel zu sehen

The Horsehead Nebula (IC 434) was my little side project in late winter; the total exposure time of this image is 7h 49min (North is left). Processing turned out to be surprisingly difficult, since the nearby star Alnitak left a lot of reflections in the field of view 🔭

Not sure it’s a problem with painted things. This is our ceiling.

UN official warns Strait of Hormuz dispute is disrupting global food supply To discuss the global stakes of the impasse in the Strait of Hormuz and its impact on deepening humanitarian crises, Geoff Bennett spoke with Jorge Moreira da Silva, the executive director of the UN’s...

"We are mostly concerned about the consequences of the disruption on fertilizers," says Jorge Moreira da Silva. "If we miss the planting season, the farmers, particularly in Africa, won't have productivity. The prices will go up and hunger and starvation will be spread." https://to.pbs.org/4tKU0wq

A few months ago there was a rather mortifying incident in which termites suddenly swarmed out of the vaulted wood ceiling in our living room *while someone was visiting.* A So Cal phenomenon.

Scheduled the fumigation so now we are spending all free time doing the prep work for that. 😭 IYKYK.

Re: Librarian Spy, which looks interesting—I recently read a NF book, “The Spy in the Archive” by Gordon Corera. Pretty quick-moving and fun to read despite sober topic.

If I had known your town had such a gorgeous library I might have stopped there on my recent trip to MA! 😍

I finished revising the two chapters of the Frost book that formed the basis of my talk in Salem. (Yay!) It’s always striking to me how helpful it is to give a talk on a chapter before finishing it. You streamline your argument, and you learn what people find puzzling or particularly interesting.

The rain stopped this afternoon and we went birding at the San Joaquin marsh and water treatment plant. I’ve been very busy so just posting as a proof of my existence.

23 spring cookbooks that we can't put down Embrace spring's bounty with cookbooks that cover Caribbean cuisine, abuela-approved Puerto Rican recipes and the re-release of a tome for country cooking.

I can get a lot of pleasure from reading cookbooks—even before trying the recipes—and I even enjoy reading *about* cookbooks. This crop is enticing.

Super fun and informative on writing history!

A double pleasure for those of us who were listening at the inception of Drafting the Past and heard Megan Kate Nelson the first time.

I admire Kamran Javadizadeh’s writing so much.

For lovers of Frost’s astronomical imagery, there’s a great section on how the stresses in the lines of “I Will Sing You One-O” vary in a way that shows “earthly clocks hurrying to synchronize with their celestial counterpart.”

This is an actual post. This is not funny. This is beyond desperate. This is a deeply unwell man who doesn’t belong anywhere near the levers of power. Every member of his cabinet and Congress is complicit in not demanding his removal now.

The Strait of Gibraltar is lower left on the astronaut’s photo, and auroral lights over the South Pole to the upper right.

The glow to lower right is, I think, the zodiacal light, a reflection of sunlight off inner solar system dust. Venus at lower right too. 🔭

Right image is Strait from ISS.
