Searching for anomalies with graphs

• Graziella Russo (Istituto Nazionale di Fisica Nucleare)

The Standard Model is one of the most tested theories in the world and although it describes incredibly well a lot of phenomena, we know that there are others still not understood. Therefore at LHC we search for the so-called New Physics and here an innovative approach is presented. New Machine Learning algorithms can look for “anomalies” among the enormous amount of events collected in collider experiments; the events are transformed into graphs to represent efficiently complex structures of particles.

DNA Origami

• Rodrigo Rivas Barbosa

Yeah, sure, DNA is fundamental from a biological point of view by encoding "life", but arguably (not really...) one may say that DNA can be used more sensibly as tiny scaffolds for the self-assembly of nanostructures. Thanks to the flexibility of single stranded DNA and the base pair specificity (A bonds to T, and C to G), well-thought DNA sequences can spontaneously assembly to unrestricted shapes! Just like paper can be folded into different designs, DNA too but at the nanometer scale! Think about it, why care about life when you can have a 1:100000000 Mona Lisa (see figure)...
