Jun 2021: Networks with a scale-free degree distribution are widely thought to promote cooperation in various games. In Euro Physics Letters [EPL] 134 60002 (2021), we demonstrate that this is not necessarily true. For the same degree distribution and indeed the very same degree sequence, we present a variety of possible behaviour. We also reevaluate the dependence of cooperation on network clustering and assortativity.

* Jan  2021: Our paper presenting a rigorous mathematical approach on how to compare two networks with common or identical nodes, is now published in 
Bioinformatics [Oxford]. This approach immediately presents a fresh, broad and general framework to address mutagenesis and has the potential to deliver systems-level perspectives. We computationally explore phenotypic alterations arising from  mutations in five microbes, each from a different taxon. We generate a mutant of Mycobacterium smegmatis mc2155, which is resistant to mycobacteriophage D29 and is characterised with significant phenotypic alterations. We scrutinise the effectiveness of our procedure through extensive theoretical and experimental tests on this system.
