The game of Go• The rules of Go are so elegant, organic

and rigorously logic, that if intelligent life exists elsewhere in the Universe, it almost certainly plays Go.

HALICIN = potent bactericidal activity against wide spectum of pathogens

➢Training of deep neural network to predict growth inhibition of E.Coli, using library of 2.335 molecules

➢Application to library of >107 million compounds

➢Selection of a list of candidates

➢Halicin is structurally divergent from conventional antibiotics

Make Healthcare Human Again

By these means we may hope to achieve not indeed a brave new world, no sort of perfectionist Utopia, but the more modest and much more desirable objective –

a genuinely human society
