Chapter 1 of Moby Dick, page 1 

The phrase ‘Call me Ishmael’, the first sentence of the book, is highlighted in blue, with careful highlighting on the very big C at the start. Above this, written in ballpoint pen ‘His name’

Love the glimpse into the beautiful mind that notated this used copy of Moby Dick I got

Why curling rocks come from just two spots on Earth The rocks used in the Olympic sport of curling come from one island in Scotland and one quarry in Wales. What makes them so special?

Had a blast speaking to curler and geologist Derek Leung about the geology of curling rocks. 🥌 🧪

Rand Paul up to his usual dipshittery. "The NSF spent $8 billion to study whether Japanese qual are more sexually promiscuous while on cocaine"

The total NSF budget was 9 billion. I doubt they spend 89% of it on quail.

Humans Made Poisoned Arrowheads Thousands of Years Earlier Than Previously Thought The use of poison on arrows marked a revolution in human hunting technology—new evidence suggests it happened tens of thousands of years earlier than previously known

This is such a cool finding--the oldest direct evidence of poisoned arrows. Poisoned hunting weapons were a game-changing innovation for our ancestors. Absolutely incredible that researchers found traces of plant toxins on these tiny arrowheads from 60,000 ago 🤯🏹 🧪

The man who mistook his imagination for the truth The disappointing reality of one of my (ex-)heroes, Oliver Sacks

Oliver Sacks was a hero of mine. I couldn't let @rachelaviv.bsky.social’s brilliant piece pass without comment. My latest, on why Sacks's fictions are so much worse than those of your garden-variety journalist fabulist.

How Did DOGE Disrupt So Much While Saving So Little?

On DOGE’s watch, federal spending did not go down at all. It went up. But is still led to cuts that closed offices, canceled programs and deprived people of food, medicine and other aid.

CDC Vaccine Panel Scraps Guidance for Universal Hepatitis B Shots at Birth New guidance from the CDC’s vaccine advisory panel would do away with a decades-old universal birth dose recommendation for hepatitis B that helped cut infections by 99 percent in the U.S.

An CDC advisory panel voted today to end universal Hepatitis B vaccination at birth. If adopted by CDC, this would reverse a longstanding policy that has been widely effective at lowering hep B cases and deaths in children, @laurenjyoung.bsky.social reports www.scientificamerican.com/article/cdc-...

Five guys who simply ooze late '90s Florida youth group pastor from every pore, hanging out at a bar. In the center is a young man with a handkerchief tied over his head and a Corona in his hand. Even in these tender years, you can tell this man has got some sauce in the way the rest of his pals don't. It's his stare, his slightly pouted lips. Even if you didn't know who he was, you'd guess he was meant for big things. You'd be right. It's Oscar Isaac.

Every day someone new learns that Oscar Isaac was in a late 90s Christian ska band. Who will today’s person be.

Transforming Presidential Health Care: Insights from a Former White House Doctor A former White House physician reveals the medical realities of caring for the president of the U.S.

On today's Science Quickly, I interviewed a former White House doctor about the president's care, aging and more: "It is a fact of science, it's not a political attack, that humans past the age of 60... start to have cognitive decline."

"We have a gerontocracy."
