There is a slow-moving silver shape drifting over the forests and cities of North Rhine-Westphalia. From the ground, it looks almost ceremonial -- a Zeppelin NT gliding through the air as though time had reversed by a century. Inside, sensors are humming. And Eva Pfannerstill is watching the data appear.

A creature's internal temperature plays a big role in its behavior. Over the past decades our understanding of the behavior of various dinosaur groups has evolved. A combination of bone histology (patterns of bone growth as an individual develops from juvenile to adult), energetics gleaned from anatomy and ecology, and fossil geographic distribution all suggest that at least some dinosaur groups evolved an ability to regulate their internal temperature (endothermy).There is evidence from isotope work that some species within Theropod, Sauropod, and Ornithician dinosaur groups maintained a high body temperature. In contrast, specific biomolecules and inference of ecologic preference suggests that many other dinosaur lineages did not maintain endothermic metabolism. Dinosaur physiology and thermal regulation continues to be studied and debated.What has been missing is a consistent and reliable method for ascertaining their body temperature.Recently Randon J. Flores and coworkers applied a technique known as carbonate clumped isotopes to fossil teeth (enamel) of specimens of Tyrannosaurus rex to determine its body temperature. The sample was from the Cretaceous age Hell Creek Formation, North America. This technique measures the abundance of C13-O18 bonds in carbonate minerals that make up the enamel. These bonds of the heavier isotopes of carbon and oxygen are more common at lower temperatures. They are not affected by the isotope composition of the reacting fluids and is a direct indicator of the temperature of mineral formation.

 In the opening of my most recent post where I wrote about the essential role in science of challenging conclusions,  I quoted Carl Sagan from The Demon-Haunted World (1996) about certitude being applicable only to pure mathematics.  I had only read the excerpt from Sagan's book that Richard Dawkins included in his always rewarding The Oxford Book of Modern Science Writing (2008).  I decided to read the book as a bit of after-the-fact due diligence.  What if I'd been wrong about what Sagan was saying?  (I wasn't.)

Trust in science appears to be in crisis these days. So-called 'alternative facts' often fall on fertile ground, particularly amongst populist circles. During the Covid-19 pandemic in particular, this loss of trust was evident, for example, in the 'Querdenken' movement, which, amongst others, deliberately questioned protective measures and the effectiveness of vaccines. But what exactly does the pandemic have to do with uncertainty, and how can trust be built through better science communication?
