Can you crowdsource your way to discovering a new drug?
Alpha Lee's startup PostEra launched a crowdsourced effort (called Covid Moonshot) to discover drugs that are effective in treating covid-19. This was the first of its kind effort that combined research efforts from several groups across the world to design a drug that treats covid-19, is free from patents and can be made cheaply and easily anywhere in the world.
== What we talk about ==
0:04 - Introduction
1:28 - What does your company, PostEra, do?
4:58 - Why is the traditional method of discovering drugs inefficient and hard?
9:52 - How do you find whether a computationally discovered drug will work?
11:25 - How do you optimize the drugs for toxicity, solubility, and other properties?
12:03 - How are you able to come up with a chemical synthesis pathway in a finite time?
16:44 - What are the areas where deep learning models have become better than humans in drug development?
19:18 - What’s the origin story of Covid Moonshot? How did it grow into what it is now? 25:24 - How was the experience managing people from around the world working on this project, especially when there is no central authority?
27:47 - The process of finding the target molecule
34:17 - Since Covid moonshot is all pro-bono and you are not filing for a patent, how do you see the process of regulatory trials, which is very costly, being done?
37:19 - By the time your drug comes, do you think the Covid-19 will be a much lesser threat? 39-49 - Do you plan to use the same approach for different diseases? And do you also envision driving the whole process of drug discovery in the future, and not just enablement?
41:41 - How do you align your science research interests with commercial interests?
43:46 - Haș an insight, while working on a problem, inspired a scientific question?

Schizophrenia affects 20 million people worldwide and there's no treatment for it.
There is growing evidence that psychedelic drugs like psilocybin (as found in "magic mushrooms") could help treat it. I explore this fascinating topic with Gaige Clark who writes a popular blog https://mad.science.blog detailing the science of mental illnesses and their potential treatments.
== What we talk about ==
0:04 - Introduction

6:21 - What is schizophrenia?
9:10 - How common is schizophrenia? How does it impact people’s lives?
11:16 - The role of genetics and stress in being prone to these disorders including schizophrenia?
15:44 - Making sense of hallucinations as an aftereffect of schizophrenia
20:05 - How do you define psychedelics? And how do they work?
41:35 - It seems counterintuitive that the drugs which make you hallucinate can cure you of the hallucinations happening because of schizophrenia - how is this happening?
59:50 - How much have we progressed in using psychedelics as a therapy?
1:02:43 - Is psychedelics being researched upon to be used as a cure for anything else apart from schizophrenia and addiction?
== About the guest ==
Gaige Clark is currently studying psychology at UC Merced, focusing on neuroscience, pharmacology, and neuropsychology, especially in relation to psychedelic therapy. He reads bucket loads of papers on the science of mental disorders and documents them on this blog. Through personal experiments and emerging support in science, he now believes in the hypothesis that psychedelics may treat schizophrenia.

== About the guest ==
Professor Lee Cronin is the Regius Chair of Chemistry in the School of Chemistry at the University of Glasgow, UK.
He is interested in the intersection of computation, life and chemistry. His research group is trying to recreate life from scratch by mimicking the atmospheric and terrestrial conditions of early Earth. In his pursuit of figuring out how life arises, Prof Lee Cronin has ended up pushing chemistry to its limits, the most recent manifestation of which is the chemputer - a computer that can be programmed to synthesize almost any chemical you can imagine.
Unlike many other scientists who study the origin of life, he is unique in his approach in trying to study life from its inorganic precursors - that is, how can complex organic molecules that life needs can form from inorganic molecules that get formed in the core of stars.
How do our bodies know what to become?
There are no instructions in our genes that code for the exact 3D structure of our bodies. There's no tiny human contained in our DNA. So, what powers the transformation of the first cell in the embryo to a full-blown organism?
Dr Michael Levin is attacking this problem and, in the process of answering it, his lab is uncovering an entirely new way of looking at biology.

== About the guest ==
Michael Levin is a Distinguished Professor in the Biology department at Tufts and serves as director of the Allen Discovery Center. He holds a PhD in biology from the Harvard University. At Tufts, his research group is interested in figuring out how our bodies know what to become.
He believes that what guides our body plans is bio-electric communication between different units. Our bodies take shape the way they have because each of our subunits - cells, tissues, organs - collectively decides it to be that way.
Hinting at the perceived sluggish rate of innovation in recent decades, Peter Theil famously said that “we were promised flying cars and all we got is 140 characters”.

== About the guest ==
Dr Philip Goff is a professor in the Department of Philosophy at the University of Durham in the UK. He’s the author of a book called Galileo's Error in which he defends panpsychism, the view that consciousness is a fundamental and ubiquitous feature of the physical world.
He acknowledges it sounds a bit crazy, but in his book and research papers he tries to show that it avoids the difficulties faced by its rivals which are materialism (consciousness can be explained in terms of physical processes in the brain) and dualism (consciousness is separate from the body and brain).
Balaji is a deep thinker on crypto and its implications. Formerly the CTO of Coinbase and General Partner at Andreessen Horowitz, he’s seen how technologies evolve over time, which ones change the world and which ones fizzle out as a fad.
He believes crypto technologies such as bitcoin represent the former. To him, crypto will emerge as something that’s as important as the Internet and influence our society for decades to come.

The way science is funded today is broken.
Writing grant proposals for raising funds takes a significant amount of time and, unlike papers, they aren’t published in journals or valued for their scientific contribution. With grant rates now in single digits in many fields, scientists are spending more time raising funds than doing actual science. Is there a better way?
Kevin Gross, professor at North Carolina State University, urges us to explore alternative ways of funding science. One such suggestion is using partial lotteries to award grants which, according to the models he’s built, generate more scientific output for the society than current methods.
What we talk about
1:55 – How did you get interested in meta-science?

54:04 – Is there any empirical evidence for the alternative ideas you have for funding systems?
57:42 – Why should society care about how science is funded?
Can we eliminate suffering?
David Pearce thinks so. He is a British philosopher who has played a key role in defining and promoting transhumanism – a movement that challenges humans to explore what it means to go beyond our biological evolved limitations and constraints.
He is most known for Hedonist Imperative, a manifesto he wrote in 1995 which outlines how modern technology can and should be used to eliminate all suffering in all sentient life, replacing it with bliss. David calls this the abolitionist project.

49:21 – Are short-term pleasures (like smoking) that turn into addiction worth it?
51:44 – Are plants consciousness and if so, what is your take on veganism and vegetarianism?
55:36 – Why would a human brain produce consciousness and a plant would not?
1:00:15 – Have you noticed any progress since the time you published ‘The Hedonistic Imperative’?
What are the origins of language? What role did evolution play in it?
In this episode, Micheal Corballis backs up the idea that languages evolved gradually and some version of it existed much before Homo Sapiens arrived on the scene.
About the guest
Michael Corballis is an emeritus professor at the Department of Psychology at the University of Auckland. His research interests intersect cognitive neuroscience with language and evolution.
