I got a chance to tour Hanford and the B Reactor last year - well worth taking the tour if you’re a science nerd like I am.
The government gives tours of the Hanford site, including inside the B-Reactor building, and you can walk up pretty close to the reactor face. Some tours (not the one I was on) even let you take pictures and stuff. The amount of space out there between sites is pretty staggering, but you can get a feel for why they… Read more
My mom was a little girl in Richland when this happened, I remember all the talk about the Downwinders when this came to light in the 1980s. So far she’s still generally healthy. Crazy to think about the “just to see what happens” mentality that permeated the early nuclear age.
Back in the early ‘80s, when I was 14, I did a study evaluating amphetamines on sleep at Columbia Presbyterian. Saw an ad in the Village Voice, signed up (mom was there and involved), got IV drugs, had a million sensors all over my head, tried to sleep, and after about a week walked away with $2 grand.

I find it amazing that Neuroscience students aren’t required to go into a MRI machine so they know what it is like.
Memphis International is like this as well with Fed Ex. Not a whole lot of commercial flights go out of there, but it’s the busiest cargo airport in the world. It’s amazing how much product moves out of these facilities.
I think the unspoken point is that propagating and growing the crops (and making the cultural and environmental changes necessary to ensure the crops keep growing) is a more effective “saving” method than locking them in cold storage.
Hmmm...note to self: write a rough draft about a small team representing man’s last hope on a dying world a couple hundred years after the apocalypse going to the “Great Stone Garden” far to the north, across the great barren sea, to reclaim humanity’s agricultural heritage and save mankind.
According to the linked article it wasn’t the rocks themselves they dated, but the sediments and stratified deposits they were found in. That allowed them to date the era when the rocks were shaped and used. They have to be older than the deposits above them, younger than the deposits below them. That gives you a… Read more
I would also be amenable to demolishing the entire Amazon and replacing it with a gigantic theme park, service by monorails, that would allow rich tourists to sample what the Amazon was like, but with less mess and cholera, and more high-priced concessions and pithy t-shirts.
Thank you for this article Sarah. We have many nice sounding words for new technology in Icelandic but we also have expressions that describe natures phenomenons poetically. My late teacher in field electronics, Sigursteinn H Hersveinsson coined the phrase for modulated radio waves as “á öldum ljósvakans”, translates… Read more
Since people seem interested in robots, Icelanders will sometimes say “róbot” for robot, but the Icelandic word is actually “vélmenni” which is a combination of “vél” = machine, and “mennskur” = human.
Most nouns for items are known by everyone, like lights, cameras, tripods and lenses, but verbs are less so. They’re only known within the industry. And some of the words are repurposed older words like “þysja” = “zoom” (original meaning “to bolt, run”) and “skima” = “pan” (original meaning “to scan, look around”. And… Read more
Basically. Cas9 is an enzyme that makes a cut in a DNA sequence defined by a short guide RNA. Cells have ways to repair broken DNA. If you inject a DNA sequence that is highly similar to the cut region, the cell’s DNA repair mechanisms may fill in the cut with the injected DNA sequence. This is how you can potentially… Read more
