Bi-Lipschitz embedding properties of lamplighter graphs on weighted and unweighted trees
In 2021 Baudier, Motakis, Schlumprecht, and Zsák proved that if a sequence of graphs $(G_k)_{k\in{\mathbb{N}}}$ contains the sequence of complete graphs with uniformly bounded distortion, then the sequence of lamplighter graphs on $G_k$'s contains Hamming cubes with uniformly bounded distortion and asked whether the converse holds. They suggested that a sequence of trees with edges replaced by paths of ``moderately growing'' lengths may be a counterexample. We prove that indeed this is the…

Amazon Threat Intelligence identifies Russian cyber threat group targeting Western critical infrastructure | Amazon Web Services

This tactical adaptation enables the same […]

We just had so much fun at home reading the most recent and some older german"#Jugendwort des Jahres" (words of the youth) - sorry, article in german:

Weekend #Plankton Factoid 🦠🦐
Since 2011, millions of tons of a brown algae called Sargassum has washed onto beaches in the Caribbean. The rotting seaweed releases toxic hydrogen sulfide, smelling of rotten eggs, impacting tourism and shore access. It was initially thought Saharan iron dust was the cause, but new #science
