In this episode of the a16z bio Journal Club, bio deal team partner Judy Savitskaya and Lauren Richardson discuss research that aims to enhance the efficiency of photosynthesis and carbon fixation. These two processes are used by plants and other phototrophs (like algae) to convert light energy and carbon dioxide from the air into organic matter. The pathways took millions of years to evolve, but can scientists use advances in biochemistry and synthetic biology to increase their efficiency? 

The two discussed were both published in the journal Science and are both from the lab of Tobias Erb at the Max Planck Institute for Terrestrial Microbiology. The first article, published in 2016 develops a synthetic pathway for the fixation of carbon dioxide in vitro. The second article, which was published in May, combines this synthetic carbon fixation pathway with the natural photosynthetic pathway isolated from spinach to create an artificial chloroplast.

This combination of natural and synthetic components to improve the efficiency of these pathways has a number of potential applications, including in engineering our crops to grow faster. We discuss these exciting applications, how evolution has restricted the efficiency of carbon fixation and how these engineered solutions get around that problem, and the use of microfluidics for vastly improved experimental design.

This episode is the second in a two-part series that examines the pandemic’s impact on real estate. Part 1 focused on prospective home buyers, sellers, and existing homeowners. This episode, Part 2, addresses renters and landlords.

The conversation with host Lauren Murrow features a16z general partner Connie Chan, whose experience as a landlord herself has fueled her interest in residential real estate and technology; Richard Green, the director of USC’s Lusk Center for Real Estate, and Adena Hefets, the CEO of Divvy Homes, a company that allows people to build up equity while renting a home, with the option to eventually buy it.

We begin with the pressures on renters—and the uncertainty around federal relief measures—as well as the cascading effects on mom-and-pop landlords. Then we turn to the outlook for prices and volume in the rental market, particularly in large cities like New York and San Francisco. Finally, we discuss the opportunity for tech to solve outdated and inefficient processes for both renters and landlords.

This episode is the first in a two-part series that examines the pandemic’s impact on real estate. Part 1 focuses on prospective home buyers, sellers, and existing homeowners. Part 2 (streaming on 6/17) addresses renters and landlords.

How has social distancing shaken up the market to buy? What’s the ripple effect of eviction freezes and a record number of homes in forbearance? And how can tech streamline the inefficient process of renting, buying, and selling a home?

Led by host Lauren Murrow, the conversation features a16z general partner Alex Rampell, who has invested in a number of real estate companies; Malloy Evans, Fannie Mae’s senior vice president and single-family chief credit officer;  and Tushar Garg, CEO of Flyhomes, a company that helps buyers in competitive markets by purchasing their desired house in cash, then selling it to that buyer at the same price.

The discussion starts with the impact on home prices and volume, as well as the rumored exodus from densely populated cities. Then we shift to focus on existing homeowners. Finally, we talk about ways tech can improve the system, from hard tech to fintech.

Proteins are molecular machines that must first assemble themselves to function. But how does a protein, which is produced as a linear string of amino acids, assume the complex three-dimensional structure needed to carry out its job? 

That’s where Folding at Home comes in. Folding at Home is a sophisticated computer program that simulates the way atoms push and pull on each other, applied to the problem of protein dynamics, aka “folding”. These simulations help researchers understand protein function and to design drugs and antibodies to target them. Folding at Home is currently studying key proteins from the virus that causes COVID-19 to help therapeutic development. 

Given the extreme complexity of these simulations, they require an astronomical amount of compute power. Folding at Hold solves this problem with a distributed computing framework: it breaks up the calculations in the smaller pieces that can be run on independent computers. Users of Folding at Home – millions of them today – donate the spare compute power on their PCs to help run these simulations. This aggregate compute power represents the largest super computer in the world: currently 2.4 exaFLOPS!

Folding at Home was launched 20 years ago this summer in the lab of Vijay Pande at Stanford. In this episode, Vijay (now a general partner at a16z) is joined by his former student and current director of Folding at Home, Greg Bowman, an associate professor at Washington University in St. Louis, and Lauren Richardson. We discuss the origins of the Folding at Home project along with its connection to SETI@Home and Napster; also the scientific and technical advances needed to solve the complex protein folding and distributed computing problems; and importantly what does understanding protein dynamics actually achieve?

The way we deliver healthcare has changed enormously over the last century, shifting from house calls by doctors to your own to institutionalized settings like hospitals and clinics. But now that trend has started to shift again, as some of the care we get in the hospitals and clinics has been “unbundled” back towards home settings for chronically ill patients or seniors. And now, of course, the impact of COVID-19 has created a huge sudden demand for home-based care, as all of us try to figure out how to manage certain healthcare needs at home.

So, is home-based healthcare better? And what do we truly need to deliver the best care to patients, in their own homes? What do we gain and lose in different care delivery settings, and what shifts of mindset and new logistical processes do we need now, to best accomplish unbundling healthcare into the home? In this conversation, Vijay Kedar, CEO and cofounder of Tomorrow Health, a tech platform that delivers the products and services needed for home-based care; Sachin Jain, physician, previous CEO of Caremore and Aspire Health; part of the founding team at CMMI, the Centers of Medicare and Medicaid Innovation, now incoming CEO of The Scan Group and Healthplan; and a16z General Partner Julie Yoo join a16z’s Hanne Tidnam in conversation to talk about where we are today and where we are going in home-based healthcare.

Primary care was meant to be the front door to the healthcare system, but in some ways never set up for success to begin with. We need a new operating system for primary care—one with a different, deeper understanding of the patient, the context of their world around them, and the processes we have in place to figure out who sees a doctor and when, to use the system most efficiently.

In this episode of the a16z Podcast, we talk about what the primary care of the future should actually look like; what kind of data about patients we should be collecting, from where, and to tell us what; how you ask the right questions of that data, to use the resources of our  healthcare system most efficiently and for the best care; and what the PCP of the future might look like. Joining us for the conversation are General Partner Julie Yoo, physician entrepreneur Ivor Horn, a primary care pediatrician for more than 20 years, and Jeff Kaditz, CEO and founder of Q.bio, a platform that identifies and monitors each individual’s biggest health risks.

 We cover the tricky but important topic of Section 230 of the Communications Decency Act. The 1996 law has been in the headlines a lot recently, in the context of Twitter, the president’s tweets, and an executive order put out by the White House on “preventing online censorship”. All of this is playing out against the broader, more profound cultural context and events around the death of George Floyd in Minnesota and beyond, and ongoing old-new debates around content moderation on social media. [Please note this episode was first published  May 31.] 

To make sense of only the technology and policy aspects of Section 230 specifically — and where the First Amendment, content moderation, and more come in — a16z host Sonal Chokshi brings on our first-ever outside guest for 16 Minutes, Mike Masnick, founder of the digital-native policy think tank Copia Institute and editor of the longtime news & analysis site Techdirt.com (which also features an online symposium for experts discussing difficult policy topics). Masnick has written extensively about these topics — not just recently but for years — along with others in media recently attempting to explain what’s going on and dissect what the executive order purports to do (some are even tracking different versions as well).

So what’s hype/ what’s real — given this show’s throughline! — around what CDA 230 precisely does and doesn’t do, the role of agencies like the FCC, and more? What are the nuances and exceptions, and how do we tease apart the most common (yet incorrect) rhetorical arguments such as “platform vs. publisher”, “like a utility/ phone company”, “public forum/square” and so on? Finally: how does and doesn’t Section 230 connect to the First Amendment when it comes to companies vs. governments; what does “good faith” really mean and what are possible paths and ways forward among the divisive debates around content moderation? All this and more in this extra-long explainer episode of 16 Minutes, shared here for longtime listeners of the a16z Podcast.

For a SaaS company, it’s easier to move upmarket than down, and this gives SaaS startups the advantage against incumbents. In this episode,  David Ulevitch and our newest enterprise general partner Kristina Shen look at the SaaS go-to-upmarket with a focus on how to price for the move, including why so many founders underprice, how to think about free versus paid trials, and navigating the transition to larger accounts.
