The role of TV in geoscience communication

November 23, 2012

This is now the fifth part in a series exploring the public communication of geoscience, this time focusing on the role that television can play as a communication medium. It is based on, and a development of the ideas conveyed within a paper by Iain Stewart, no stranger to TV himself, and Ted Nield, a writer of popular geoscientific novels and Editor of Geoscientist magazine published by the Geological Society.

The four previous posts, in order, are:

1. Why bother with communication?
2. What do the public already know about geoscience?
3. Who are this ‘public’ we are aiming to communicate with?
4. What is the role of the mass media and newspapers in communication?

Flying on the wings of dinosaurs

November 22, 2012

Archaeopteryx lithogaphica is probably the most iconic dinosaur ever. When it was first discovered, it was heralded as the holy grail of palaeontological findings, as it helped to consolidate the evolutionary continuum between theropod dinosaurs and modern birds. What it also represents though, is an example of the evolution of scientific thought through time. Palaeontologists, mechanists and developmental biologists have long puzzled about where exactly this ancient-winged half-bird half-dinosaur fits into the evolutionary tree of life. Perhaps of equal importance, is what it can tell us about the evolution of one of the most extraordinary biological innovations of all time – the development of wings and powered flight.

Mum! MUM!! Mum, are you watching? Watch me fly! MUUUM!!

Geoscience in the news

November 19, 2012

This is the fourth part of a series looking at how we should effectively communicate geoscience, based largely on a recent paper by Iain Stewart and Ted Nield. The previous post attempted to address the insanely impossible question of ‘who are the public?’, when it comes to public engagement’. It seems that this is very much a disciplinary issue, each with their own collective suite of hurdles and mountains to climb. The conclusion, I think, was that although identifying various ‘publics’ and sub-categories based on social traits, the use of this is only in identifying some sort of strategic framework for science communication to operate within, when what we really should be doing is ignoring that, and actually going out there and actually doing things. At the recent Festival of Geology in London, I saw kids (and adults!) having a blast playing with robotic trilobites. As a form of communication, I’d say doing practical things like that are infinitely more valuable than discussing which public group the trilobites are trying to commune with (as an example).

Almost as cool as this rideable trilobite!

Peering into dinosaur skulls – the best application for medical technology

November 19, 2012

Most of what we know about dinosaurs comes from their skeletal remains. Rarely, we get tiny glimpses into their soft tissue anatomy through skin impressions and even rarer, preserved tissue fragments, mummified over time, and their ecology and life habits through combining interpretation of this from what we can glean from trace fossils (footprints, poop, etc.). Palaeontologists are also taking the first steps to digitally reconstructing their muscular systems through looking at muscle attachment points on bones and comparing this with their living archosaur relatives, crocodiles and birds. But what if we could actually peer inside their skulls to look at their brains? Brains, unsurprisingly, are not preserved in the fossil record. This is due to two, equally scientifically valid points – brains are nutritious, and when a dinosaur dies, their brains are usually scavenged by other carnivores so that they can assimilate the brain-host’s knowledge (and their hearts, for courage)*, and secondly, soft tissue does not readily preserve under normal taphonomic conditions, and only exceptionally rarely under the right conditions, which are typically deep marine anoxic environments (not something any known dinosaur is yet known to have inhabited).
