The Buzz: A science and engineering podcast Faculty of Science and Engineering, University of Manchester

Chances are you’ve heard of it. Quite possibly you know how it works. Perhaps you’ve even seen it in action. But are you aware of its immense potential? To explore this – and much more – we sat down with Dr Marco Domingos. Originally from Portugal, Dr Domingos is a Senior Lecturer in the Department of Mechanical, Aerospace and Civil Engineering here at The University of Manchester, and specialises in 3D bioprinting and additive manufacturing.

We recently cought up with three of our acacdemics who work on the Large Hadron Collider (LHC) at CERN: Chris Parkes, Will Bertsche and Marco Gersabeck. Additionally, we spoke to recent University of Manchester graduate Jonathan Langford, who completed a PhD based on the experiments with which he was involved at CERN. In this episode, you can hear Chris, Will, Marco and Johnno talk about their work. We also asked them about whether the experiments they do can have wider benefits for society as a whole, and whether the sometimes “tabloidy” nature of the reporting of their work frustrates them. You can also hear Johnno - who graduated in 2017 - talk about his academic journey, which led him from almost dropping Physics at A level, to obtaining his PhD with a thesis on “measuring the properties of the Higgs Boson.” So if you’d like to discover which particular fruit is a good source of positrons, or what happened when an equipment supplier decided that the work being done at CERN was “evil,” then listen right here.

You may have heard about the proposal to use astronauts' blood plasma, as well as other human waste products, to manufacture "space bricks," by binding the fluids with loose rock and Martian soil - a process known as in-situ resource utilisation. These bricks could then be used to build structures on the moon and Mars as part of future space exploration - indeed, we covered the research in a blogpost last year. Well, in order to get a more in-depth explanation, Kory and Enna caught up with Dr Aled Roberts of the Manchester Institute of Biotechnology and the Department of Chemistry, who explains the theory, and the practical considerations, behind the blood-curdling proposal. Any future long-term planetary exploration would require buildings with exceptionally thick walls, to protect astronaunts from the effects of solar radiation. When you consider that the cost of transporting a single brick to Mars can cost more than a million British pounds, the future construction of a Martian colony could seem prohibitively expensive. 

Volcanoes. We can all picture them. But how much do we actually know about them? What are they? Why do they erupt? And, is the common perception of them – huge volcanic craters atop mountains, spewing magma – accurate? To help us answer these questions and more we speak to PhD student Marissa Lo (@MarissaLoBot). Marissa, host of the brilliant Earth and planetary science podcast The Cosmic Cast, is currently finishing her PhD studies in lunar volcanism. We cover hot topics such as predicting eruptions, environmental impact and how volcanoes can actually benefit us. Plus, of course, Marissa’s key interest area: volcanoes on the moon! So get fired up for an explosive episode of The Buzz podcast!

It's a question we've asked for a (very) long time. But could new evidence help us to finally – definitively – answer it? Just what did kill the dinosaurs? Joining us to discuss this and more is Professor Phil Manning, who recently featured in a BBC documentary fronted by Sir David Attenborough exploring this incredible new evidence, and who is working at another extraordinary dinosaur excavation site in the US as part of the Mission Jurassic project. In the episode we discuss the findings at Tanis, a spectacular dig site in North Dakota led by University of Manchester palaeontologist Robert DePalma, and talk all things dinosaurs: What were they? Are they still around today? So dig out those headphones and let's unearth the secrets of the dinosaurs!

Have you heard? The Buzz is back! Once again we're asking some of the biggest questions in science and engineering; and once again we've enlisted the help of our incredible academics. Getting us off to a stellar start is Dr Ciara McGrath, Lecturer in Aerospace Systems in the Department of Mechanical, Aerospace and Civil Engineering, and – very impressively – the Institution of Engineering (IET) Young Woman Engineer of the Year. Here she tackles a question that's astronomical in both senses of the word: Are we entering a new space age?
