CRISPR=Clustered Regularly Interspaced Short Palindromic Repeats
Cas9=CRISPR associated protein 9=DNA endonuclease
CRISPR Cas9
TARGET MALARIA
Morphological appearance of genetic males and females heterozygous (dsxF+/−) or homozygous (dsxF−/−) for theexon 5 null allele.

• Malaria muggen die uitsterven
• Tomaten die maanden bewaard kunnen worden zonder te rotten
• Planten die de opwarming van het klimaat doorstaan
• Ultragespierde politiehonden
• Koeien zonder hoornen
=//= GGO’s!
If a defect is genetic, it is druggable.

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
➢Elucidation of mechanism of action = dissipates the cytoplasmictransmembrane potential

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
