CAR T therapy is a groundbreaking medicine that uses engineered T cells to attack cancer. But CAR T cells (that is, chimeric antigen receptor T cells) can be programmed to recognize a huge range of target proteins and cell types. So what other types of cells should we train CAR Ts to recognize and destroy to improve human health?On this episode of the a16z Journal Club, a16z General Partner Jorge Conde, bio deal team partner Andy Tran, and Lauren Richardson discuss new research published in Nature in which the authors engineer CAR T cells to recognize and kill senescent cells. Cellular senescence is a process where cells stop dividing (sort of go to sleep), and in many cases this can be protective, like its role in tumor suppression, but if too many cells become senescent of if they are not removed, they can trigger inflammation and cause disease, like in atherosclerosis and type 2 diabetes. Critically, senescent cells build up as we age and contribute to a whole host of age-related conditions. In this episode we cover how the authors created these senescence killing (aka senolytic) CAR T cells, the diseases that could be treated with senolytic CAR Ts, the hurdles to getting them into the clinic, and how they could potentially be used to treat aging and possibly improve longevity.“Senolytic CAR T cells reverse senescence-associated pathologies” in Nature (June 2020) by Corina Amor, Judith Feucht, Josef Leibold, Yu-Jui Ho, Changyu Zhu, Direna Alonso-Curbelo, Jorge Mansilla-Soto, Jacob A.

We're living in an unprecedented era of online collaboration, coordination, and creation. All kinds of people are coming together -- whether in an open source project or company, an R&D initiative, a department in a company, a club or special interest group, even a group of friends and family -- around some shared interest or activity. But the word "members" is faceless, and doesn't help us really understand, support (and better design for) these communities.So in this special book launch episode of the a16z Podcast, Nadia Eghbal -- author of the new book Working in Public: The Making and Maintenance of Open Source Software published by Stripe Press -- shares with a16z editor in chief Sonal Chokshi the latest research and insights from years of studying the health of open source communities (for Ford Foundation), working in developer experience (at GitHub), researching the economics and production of software (at Protocol Labs), and now focusing on writer experience at Substack.Eghbal offers a new taxonomy of communities -- including newer phenomena such as "stadiums" of open source developers, other creators, and really, influencers -- who are performing their work in massive spaces where the work is public (and not necessarily participatory). So what lessons of open source communities do and don't apply to the passion economy and creator communities? How does the evolution of online communities -- really, social networks -- shift the focus to reputation and status as a service? And what if working in public is also about sharing in private, given the "dark forest theory of the internet", the growing desire for more "high-shared context" groups and spaces (including even podcasts and newsletters)? All this and more in this episode.

In this episode -- cross posted from our 16 Minutes show feed -- we cover all the buzz around GPT-3, the pre-trained machine learning model from OpenAI that’s optimized to do a variety of natural-language processing tasks. It’s a commercial product, built on research; so what does this mean for both startups AND incumbents… and the future of “AI as a service”? And given that we’re seeing all kinds of (cherrypicked!) examples of output from OpenAI’s beta API being shared — how do we know how good it really is or isn’t? How do we know the difference between “looks like” a toy and “is” a toy when it comes to new innovations? And where are we, really, in terms of natural language processing and progress towards artificial general intelligence? Is it intelligent, does that matter, and how do we know (if not with a Turing Test)? Finally, what are the broader questions, considerations, and implications for jobs and more? Frank Chen explains what “it” actually is and isn’t and more in conversation with host Sonal Chokshi. The two help tease apart what’s hype/ what’s real here… as is the theme of 16 Minutes.

Many don’t realize we even need to think about the possibility of security hacks when it comes to things like pacemakers, insulin pumps, and more. But when bits and bytes meet flesh and blood, security becomes literally a life or death concern. So what are the issues and risks we need to be aware of in exposing security vulnerabilities in connected biomedical devices?This conversation—with Beau Woods, Cyber Safety Innovation Fellow with the Atlantic Council, part of the I Am The Cavalry grassroots security initiative, Founder/CEO of Stratigos Security; Andy Coravos, co-founder and CEO of Elektra Labs, advisor to the Biohacking Village at DEF CON (both of whom were formerly EIRs at the FDA); and a16z's Hanne Tidnam covers how we should begin to think about addressing these security issues in the biomedical device space. What are the frameworks that should guide our conversations, and how and when (and which!) stakeholders should be incentivized to address these challenges? How did the FDA begin to think about security as part of the safety of all medical devices, including software as a medical device, and how we should think about understanding, monitoring, and updating the security of these devices—from philosophical statements to on-the-ground practical fixes and updates?

Ever since the discovery of antibiotics, microbiologists have worried about and studied how bacteria acquire resistance to these drugs. Adding to the complexity of this problem is the fact that it is not always clear whether the conditions that drive the evolution of resistance in the lab occur in patients suffering from bacterial infections.This is where the work of Nathalie Balaban -- Professor at the Hebrew University, and our guest on this episode -- comes in. The article we discuss is based on a foundation of research done in her laboratory, but this study makes the important step into the clinic by using samples from a patient with a life-threatening bacterial (MRSA) infection. By analyzing these patient samples, Dr. Balaban and her team were able to understand the conditions that lead to multi-drug resistance in a hospital setting. The work reveals how the ability of bacteria to enter a state of dormancy, also known as tolerance, can act as a stepping stone to resistance and can interfere with the efficacy of drug combinations. Our conversation covers what tolerance is, the conditions that promote tolerance, how it can lead to resistance and impact drug combination therapies, and lastly, integrating this new understanding into clinical microbiology protocols."Effect of tolerance on the evolution of antibiotic resistance under drug combinations" in Science (January 2020) by Jiafeng Liu, Orit Gefen, Irine Ronin, Maskit Bar-Meir, Nathalie Q.

A dive into the sociological, operational, and tactical realities of this murky underworld, Lusthaus and de la Garza discuss who the players are, what they are motivated by, and specialize in—as well as how basic ideas like trust and anonymity function in a world where no one wants to get caught. How do criminal nicknames function as brand? Which countries tend to specialize in what kinds of crime, and why? And most of all, what changes when you begin to think of the business of cybercrime as an industry?

Dr. Marty Makary—surgical oncologist at Johns Hopkins University School of Medicine, and health policy and innovation expert—has long been a passionate advocate for transparent pricing in the healthcare system. We don’t talk enough (or really at all) about price in healthcare, says Makary (instead, we talk about cost). But shedding a light on prices in healthcare—from not just what those prices are but how prices are set and the value we all receive as consumers of the system overall—can help us measure quality in medicine, and be a driver for real behavioral change in the healthcare system, correcting many of the unintended consequences of a fee-for-service system like surprise billing or unnecessary medical procedures.In this conversation with a16z General Partner Julie Yoo, Makary and Yoo discuss what price transparency in the healthcare system could really do; how we can "steer" towards the good physicians who are not just highly skilled, but make the right judgment calls based on need and holistic health, not cost; how we might distinguish between high value and low value through medical appropriateness; and how we might gain clinical wisdom from other kinds of scientific discovery beyond randomized controls, especially during the wartime protocol of COVID-19.

More than 98% of the information on the web is lost within 20 years, and huge gaps exist in our digital and cultural history. Zoran Basich and Alex Pruden of a16z talk to Brewster Kahle and Sam Williams, who are using different approaches to attack this problem. Brewster cofounded the Internet Archive, which is well known for creating the Wayback Machine that crawls a billion URLs every day. Sam cofounded Arweave, a company that uses decentralized crypto networks to store information forever. For both of them, this issue has implications that go far beyond just data storage. It touches on issues of censorship, government manipulation of information, and how historical context is necessary for well-functioning societies. They discuss how decentralized models offer the promise of building a next-generation web that works better for users.
