Glasgow doctor Margaret Todd (two "d"s) also has a radium connection. She came up with the word "isotope" for Frederick Soddy, when he realised that thorium and uranium decay produced nuclearly-different versions of the same element - radium in 1913. <a href="https://mastodon.scot/tags/MargaretTod" class="mention hashtag" rel="nofollow noopener" target="_blank">#MargaretTod</a> <a href="https://mastodon.scot/tags/MargaretTodd" class="mention hashtag" rel="nofollow noopener" target="_blank">#MargaretTodd</a> <a href="https://mastodon.scot/tags/Radium" class="mention hashtag" rel="nofollow noopener" target="_blank">#Radium</a> <a href="https://mastodon.scot/tags/Isotopes" class="mention hashtag" rel="nofollow noopener" target="_blank">#Isotopes</a>

ScienceActuallyStrontium-90 (Sr-90) and cesium-137 (Cs-137) are radioactive isotopes that didn’t exist before the 1940s. In art forensics, if a painting claimed to be from before 1945 contains trace amounts of these isotopes in the paint or other materials used in the artwork, it strongly suggests it’s a forgery.Thanks for sharing, Ilias I.!<a href="https://sfba.social/tags/science" class="mention hashtag" rel="nofollow noopener" target="_blank">#science</a> <a href="https://sfba.social/tags/sciencefacts" class="mention hashtag" rel="nofollow noopener" target="_blank">#sciencefacts</a> <a href="https://sfba.social/tags/isotopes" class="mention hashtag" rel="nofollow noopener" target="_blank">#isotopes</a> <a href="https://sfba.social/tags/radioactive" class="mention hashtag" rel="nofollow noopener" target="_blank">#radioactive</a> <a href="https://sfba.social/tags/strontium90" class="mention hashtag" rel="nofollow noopener" target="_blank">#strontium90</a> <a href="https://sfba.social/tags/cesium137" class="mention hashtag" rel="nofollow noopener" target="_blank">#cesium137</a> <a href="https://sfba.social/tags/artforgery" class="mention hashtag" rel="nofollow noopener" target="_blank">#artforgery</a> <a href="https://sfba.social/tags/artforensics" class="mention hashtag" rel="nofollow noopener" target="_blank">#artforensics</a>

Andy BakerSometimes I get to join some interesting collaborations. Earlier in my career, my climate research was largely on reconstructing records of past North Atlantic climate from cave stalagmites. And then I moved continents and my career changed to focus on groundwaterHowever, over the last year, I have got back into some of the questions related to European climate of the recent past. That is thanks to an old collaborator, Binggui Cai, who asked me to contribute to another cave stalagmite study. In eastern Europe, replicated stalagmite records from multiple caves suggest that the strength of the North Atlantic Jet (aka 'the jet stream') in winter has strengthened over the last 140 years and is outside the range of the previous millennia. Why eastern Europe? It is a climate 'hotspot' for understanding the strength of moisture that comes from the Atlantic. When the winter jet stream is strong, that moisture reaches the region. When it is weak, the moisture comes from the Mediterranean. Each moisture source has a different water isotope composition, and that is what the stalagmites are recording.Having worked through all the stalagmite proxy data, the climate signal seems robust. Interestingly, it differs from recently published proxy data for the North Atlantic Jet from Greenland ice. And what climate change process has led to this change in the North Atlantic Jet?It is a paper that raises new questions, and if it sounds interesting, the reference and link are here:Miaofa Li et al. 2023. The strength of the winter North Atlantic jet stream has deviated from its natural trend under anthropogenic warming.
