Everything is built from tiny blocks
Atoms are the smallest building blocks of everything — your desk, the air, even you. Snap a few together and you get a molecule.
Rearrange the blocks, make something new
Use the same atoms in a different pattern and you get a totally different material. One shape might be harmless. Another might be a medicine!
Meet the troublemaker
This germ has a special slot — like a keyhole. If we can plug that keyhole, the germ stops working and people get better.
Which key fits the lock?
A medicine is like a key shaped to fit that keyhole. But there are more possible key shapes than stars in the sky — testing them one by one would take longer than a lifetime.
AI checks millions of keys — fast
A computer using AI can look at millions of key shapes in seconds and guess which ones will fit. It sorts the maybes from the winners, so scientists only build the best few.
A new medicine is born
Scientists build the top keys for real and test them. When one clicks into the keyhole, the germ switches off. That's a brand-new medicine — found with the help of AI!
