Steve Quake and Charlotte Bunne: The Holy Grail of Biology

âEventually, my dream would be to simulate a virtual cell.ââDemis Hassabis
The aspiration to build the virtual cell is considered to be equivalent to a moonshot for digital biology. Recently, 42 leading life scientists published a paper in Cell on why this is so vital, and how it may ultimately be accomplished. This conversation is with 2 of the authors, Charlotte Bunne, now at EPFL and Steve Quake, a Professor at Stanford University, who heads up science at the Chan-Zuckerberg Initiative

Lotte Bjerre Knudsen: The Scientist Who Drove GLP-1 Drugs For Obesity and Alzheimer's

The Chief Scientific Advisor at Novo Nordisk, Lotte Bjerre Knudsen, was the key force who pushed hard to develop GLP-1 drugs for treating obesity and subsequently for Alzheimerâs. She was recently recognized by the 2024 Lasker Medical Research Award, and the 2024 AAAS Bhaumik Breakthrough of the Year Award. That recognition is richly deserved, since it is unclear if the GLP-1 drug path to obesity treatment, and all of the associated benefits, would have been seen at this time without her influence. Thatâs especially true given the mystery for why people with Type 2 diabetes (for which these drugs were used...
Ardem Patapoutian: The Pervasive PIEZO Channels

Piezo touch and pressure-sensing ion channels are showing up everywhere as the explanation for physiologic phenomena, both at the macro and micro levels. Ardem Patapoutian, my friend and colleague at Scripps Research, discovered these receptors back in 2010 and was awarded the Nobel Prize in 2021 for his work. As youâll see/hear from our conversation, the field has exploded. And youâll get to know Ardem, who is such a fun, charismatic, and down-to-earth person. He also recently got a unique tattoo (videos below) and I wonder (unlikely) if any other Nobel laureates have one related to their discovery?!
Mark Cuban: A Master Disrupter for American Healthcare

American healthcare is well known for its extreme cost and worst outcomes among industrialized (such as the 38 OECD member) countries, and beyond that to be remarkably opaque. The high cost of prescription drugs contributes, and little has been done to change that except for the government passing the Affordable Insulin Now Act at the end of 2022, enacted in 2023. But in January 2022 Mark Cuban launched Cost Plus Drugs that has transformed how many Americans can get their prescriptions filled at a fraction of the prevailing prices, bypassing pharmacy benefit managers (PBMs) that control 80% of US prescriptions. That was just the...
