We’re back with the first episode of series 2, featuring Paul Barrett discussing Dinosaur discoveries from around the world. Most species people are aware of are ones found in North America but dinosaurs have been found on every continent on Earth.
In the show we look at specimens such as Mantellisaurus, Megalosaurus, Giraffatitan and Stegosaurus and finds from Europe, Africa and Antarctica.

To kick start our Citizen Science blog for 2016, Olivia Philipps and Caroline Steel, Science Communication students from Imperial College London, have produced a series of three podcasts interviewing Dr. Anne Jungblut, the lead researcher of The Microverse project.
In the podcasts, Olivia and Caroline pose questions asked by students from The Long Eaton School, Nottingham, and Prospect School, Reading, who participated in the project.
In this first one we find out what inspired Anne to pursue a career in microbial research:
Produced by Olivia Philipps and Caroline Steel. With thanks to The Long Eaton School for contributing questions and Helen Steel for posing them to Anne on their behalf.
Watch this space for the second in this series of podcasts, where we’ll find out about the results of The Microverse project.
Citizen Science Project Manager Lucy Robinson introduces a Q&A with Dr Anne Jungblut for the Microverse:
In an earlier blog post, a group of students from Bedford Girls’ School described their recent visit to the Museum. The girls had taken part in The Microverse, collecting samples of microorganisms from buildings and sending them to the Museum for DNA analysis, and were keen to meet the scientists involved to find out more. We arranged for them to meet the lead researcher on the project, Dr. Anne Jungblut, to ask her some questions about the project and her wider research.
Some meteorites, called CI chondrites, contain quite a lot of water; more than 15% of their total weight. Scientists have suggested that impacts by meteorites like these could have delivered water to the early Earth. The water in CI chondrites is locked up in minerals produced by aqueous alteration processes on the meteorite’s parent asteroid, billions of years ago. It has been very hard to study these minerals due to their small size, but new work carried out by the Meteorite Group at the Natural History Museum has been able to quantify the abundance of these minerals.
The minerals produced by aqueous alteration (including phyllosilicates, carbonates, sulphides and oxides) are typically less than one micron in size (the width of a human hair is around 100 microns!). They are very important, despite their small size, because they are major carriers of water in meteorites. We need to know how much of a meteorite is made of these minerals in order to fully understand fundamental things such as the physical and chemical conditions of aqueous alteration, and what the original starting mineralogy of asteroids was like.
