Tom Gill alerted us to this study, saying “I’ve been a geology nerd for fifty-plus years. I was today years old when I learned that a type of rocks exists which is officially named… rauks.” The study is: “Limestone Sea Stacks (Rauks) Record Past Sea Levels and Rocky Coast Evolution in the Baltic Sea (Gotland […]
The Bergamo Science Festival this year has a pre-festival which includes: “a competition created in collaboration with the Caffi Museum, dedicated to rocks and minerals and conducted on the BergamoScienza Instagram profile. Two rocks will be presented by a geologist each week. The aim is to reproduce the study that won the IgNobel prize for […]
What are the sounds that come from trees when those trees are hit by rocks thrown by chimpanzees? A new study addresses that question: “Chimpanzees use tree species with a resonant timbre for accumulative stone throwing,” Ammie K. Kalan, Eleonora Carmignani, Richard Kronland-Martinet, Sølvi Ystad, Jacques Chatron and Mitsuko Aramaki, Biology Letters, 18 December 2019, […]
“Many archaeobotanists say never pre-sieve the sediment sample, since they think sieving may break up the charred material. I think it can be equally bad to let large rocks and sherds bang around in the flotation tank.” —So writes Naomi F. Miller [pictured here] in “Recovering Macroremains by Manual Flotation and Sieving.”
The 2016 Ig Nobel Prize for economics was awarded to Mark Avis, Sarah Forbes, and Shelagh Ferguson, for assessing the perceived personalities of rocks, from a sales and marketing perspective. They documented their research in the study “The Brand Personality of Rocks: A Critical Evaluation of a Brand Personality Scale,” Mark Avis, Sarah Forbes, and Shelagh […]
Of these three rocks, which would you say is the most ‘confident’ ? How about the most ‘sincere’ or ‘intelligent’? Just such questions were asked in a recent study by Dr. Mark Avis (Massey University, New Zealand), Dr. Sarah Forbes (University of Birmingham, UK) and Dr. Shelagh Ferguson (University of Otago, New Zealand). Their study […]
Boxes for rocks grow from much thought and careful effort, what with the desire that each box fit snugly and well in enclosing a particular rock. Ann Macmillan, say those who know, “creates cardboard boxes for rocks that are designed to fit each rock’s individual surface. After 3D scanning them and unfolding the rock’s geometry, the […]

Dr Gábor Horváth [pictured here], who discovered that white horses attract fewer flies (described here a few months ago), now may have shed light on an old, somewhat related question about Vikings. The study is “On the trail of Vikings with polarized skylight: experimental study of the atmospheric optical prerequisites allowing polarimetric navigation by Viking […]
