Plutonium in Earth Rocks Signals Long-ago Cosmic Collision
"
"A small lump of rock pulled up from the Pacific Ocean seafloor in 1976 is giving scientists new clues about an ancient cosmic event. More than a hundred million years ago, two neutron stars collided. .."

Paper publication day is one of my favourite days! Our paper on wildfire ash chemistry is out today and #OpenAccess in the #AGU journal 'Geochemistry, Geophysics, Geosystems.' We analysed the inorganic and organic chemistry of wildfire (and prescribed burn) ashes from 4 karst areas in Australia and found that ash chemistry varies with burn severity and sampling location. Another team effort from #ANSTO, #UNSW, #UWA, #GNSScience colleagues (👋 @Andbaker )

If you are interested in the chemical tracers of wildfires, and how those might vary with burn severity, check out our new #preprint https://www.authorea.com/doi/full/10.22541/au.170689252.26414470/v1

We leached wildfire ashes and soils from karst areas, so we can better understand the speleothem palaeofire proxy signal. Another team effort, with co-authors from #UNSW (👋 @Andbaker) #ANSTO, #UWA, and #GNSScience
