World’s Largest Supercomputer v. Biology’s Toughest Problems

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?

Cybercrime, Incorporated

Cybercrime, Incorporated

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?

How Transparent Pricing Drives Healthcare Change

How Transparent Pricing Drives Healthcare Change

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.

Preserving Digital History: How to Close the Web's 'Memory Hole'

Preserving Digital History: How to Close the Web's 'Memory Hole'

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.

Alex Honnold on Human Performance (part 2) – Climbing and Entrepreneurship

Alex Honnold on Human Performance (part 2) – Climbing and Entrepreneurship

In part 1 of our series on human performance, we looked at the limits of human potential in climbing and other sports – and how we push those limits through technology and training.In this episode, recorded at our a16z innovation summit last year, Alex talks with a16z general partner and fellow avid climber Peter Levine about the risk, fear, and preparation for his free solo of El Capitan on Yosemite. While climbing is the topic, the conversation holds many lessons for entrepreneurs, and anyone else who is attempting something that’s never been done before – from how to evaluate risk versus reward, moving into the public spotlight from stealth, removing constraints to innovate on established routes, and knowing where you can fall and where you can’t. The conversation finishes with Alex’s life philosophy of living simply and giving back, including how he donates a third of all his income to the Honnold Foundation to support solar projects in underserved communities.

Alex Honnold on Human Performance (part 1) – Where's the Limit?

Alex Honnold on Human Performance (part 1) – Where's the Limit?

Is there a limit to what humans can do? And if so, how do you know when you've reached it? Welcome to part one of a two-part series on human performance with professional rock climber Alex Honnold. Alex redefined the limits of what is possible by free soloing – that is climbing with no ropes or safety gear – a 2000-foot granite rock face in Yosemite, known as El Capitan. That feat  was documented in the award-winning film Free Solo. In this podcast, Alex, a16z general partner Peter Levine (who at age 59 is still an avid ice climber), and Das Rush discuss how technology and training have pushed the limits of what's possible and how to manage the mental preparation of any big endeavor, whether its building a company, reaching a new peak, or maintaining peak performance while aging.In Part 2, recorded last year as part of our a16z innovation summit, we share a fireside chat with Peter and Alex  about the risk, preparation, and fear around Alex's free solo.  Photo credit: Shawn Corrigan
