Ammonia Leak on Station
colchrishadfield:
Station’s power relies on ammonia coolant. A few hours ago, we determined that the ammonia was leaking out of the Station and into space. At the analyzed rate, one of the Station’s cooling loops could shut down within 48 hours. It is a serious situation, but between crew and experts on the ground, it appears to have been stabilized. Tomorrow we find out for certain.

adamlaiacano:
I’m happy to finally give Sifter a name and a home. It’s a multi-armed bandit (MAB) API for testing web pages, optimizing which version (“arm”) of the test gets displayed. These arms could be article titles, ad positions, logos, colors, etc. Here’s the gist of how how a MAB test works:

Scientists explore the illusion of memory
columbiascience:
A memory might seem like a permanent, precious essence carved deep into the circuits of the brain. But it is not. Instead, scientists are discovering that a memory changes every time you think about it.
“Every time you recall a memory, it becomes sensitive to disruption. Often that is used to incorporate new information into it.” That’s the blunt assessment from one of the...

This is Part 2 of my thoughts on the state of sea-level research. Here is Part 1.
Sea-level cycles?

Last week I posted a video from Jeremy White, loosely describing how he turned LIDAR data into a stunning model of Tunnel Creek. But more modeling yet went into showing exactly where the avalanche happened and how it traveled. My colleague Graham Roberts added trees, elevation lines and an…
