New episode!! 🎙️🎉
A conversation w/ @erinhecht.bsky.social about the diversity and evolution of canine brains.
We've lived and worked with dogs for 15,000+ years, sculpting their brains and bodies along the way. What can we learn from their singular story?

This is IMO one of the biggest discoveries of the year, but you haven’t heard about it bc of a NASA press release/embargo stuck bc of the shutdown. I however have no such constraint (we’re tracking it in radio but haven’t finished the paper) so got to write about it! 🔭🧪

A fascinating new piece for @sciam.bsky.social by @squigglyvolcano.bsky.social about Hurricane Melissa being picked up by seismographs. Because the seismic record began long before the satellite era, we may be able to use older seismograms to learn more about past storms. 🧪

Radio emissions from long-period radio transients change more slowly than normal radio variations, and we don’t really know what causes that. For the first time, observations of one transient show that it also varies in X-rays at the same time, ruling out some options but not solving the mystery 🔭🧪
