When the Singing Stone was first displayed at the Museum, the massive block of vibrant blue azurite and green malachite made high-pitched sounds when the humidity changed with the weather and seasons. These noises were produced as the porous stone absorbed and released moisture from the air.

Put my hand on a bison rubbing stone today. It’s been sitting here since it was dropped by a retreating glacier at the end of the last ice age. The sides are smoothed from generations of bison rubbing on it. Good to think about that now and then

Recently, there was some controversy, because an AI user pointed their automated tools at our website, and got a warning about a prompt injection. Nothing actually happened, mind, but our anti-AI page successfully annoyed the operator and interrupted their "work."

Latest #Artemis image to drop is my newest favourite! "A New View of the Moon" ICONIC! 🔭🧪 📷: NASA images.nasa.gov/details/art0...
Earth sets at 6:41 p.m. EDT, April 6, 2026, over the Moon’s curved limb in this photo captured by the Artemis II crew during their journey around the far side of the Moon. Orientale basin is perched on the edge of the visible lunar surface. Hertzsprung Basin appears as two subtle concentric rings, which are interrupted by Vavilov, a younger crater superimposed over the older structure. The lines of indentations are secondary crater chains formed by ejecta from the massive impact that created Orientale. The dark portion of Earth is experiencing nighttime. On Earth’s day side, swirling clouds are visible over the Australia and Oceania region.

The UK has banned crypto-denominated contributions to political parties. Canada is considering doing the same.
Outside the US
The United Kingdom has decided to ban cryptocurrency donations to political parties, at least until they can implement a system to properly monitor them. They have also said they will limit political contributions from British citizens living outside of the country to £100,000 (~$134,000) per year.33 This all comes after Christopher Harborne, a Thailand-based British–Thai citizen, contributed £12 million ($15.9 million) to Reform UK last year [I98, 102]. It also follows reporting that Reform UK had not shared any of its wallet addresses with the UK’s election watchdog, preventing them from scrutinizing contributions.34 The UK Government has presented the limits as “changes to protect UK democracy from [the] scourge of foreign actors and financial influence”.Canada is now also considering legislation that would prohibit crypto donations and other “anonymous/hard to trace contributions” like money orders and prepaid cards. It’s part of a sweeping bill that would also ban most election-related deepfakes and further limit foreign political spending.35
