Discovery of a 14-protein biomarker that predicts lung cancer 5.6 years before it is diagnosed, even in non-smokers, and an anti-inflammatory medicine that prevents its progression. And, challenging dogma, the proteins are not coming from cancerous cells!

"As all scientists should know, the first step in doing science is to identify a problem to solve." "Deep learning scientists are doing this backwards: they have a solution in search of a problem. And when you have a beautiful new hammer, suddenly a lot of things look like nails."

"[Some], model in hand, go around looking around for problems to solve. Some of them have realized that DNA sequencing is super-efficient and is generating reams of data, so they’ve latched onto this." "This is not how good science gets done. You don’t start with a tool and then look for problems."

This feels a bit artificial, driven less by a real tech breakthrough and more by aggressive discounting, similar to Uber. I am curious whether the unit economics can support a viable business and whether VCs will bankroll it long enough to reach profitability (as they did for Uber).

Caramelized Onion, Cranberry and Rosemary Tahchin  Recipe
Tahchin is a Persian rice dish in which the rice is mixed with yogurt, oil, egg yolks and saffron and baked until a golden crust forms at the bottom (Persians refer to this as the tahdig) The rice on the inside becomes buttery and almost cake-like and is often layered with chicken and barberries, a tart dried fruit that has a beautiful crimson color This version incorporates common Thanksgiving ingredients like rosemary, sweet-tart cranberries and buttery onions to make a striking dish that feels more like a main than a side
