When it comes to healthcare, the topic of how expensive it is and what we can do to lower costs is always top of mind. One area with particularly steep costs is the emergency department. These are hospital departments that can take care of pretty much anything from a cut to a car wreck. But going to an emergency department for something as simple as a cut can result in a high bill for both the patient and the insurer. This is where...

If there is one rule in biology, it is that there is an exception to every rule. This includes even the basic biochemistry of DNA, which was once thought to be universal. On this episode, host Lauren Richardson and Judy Savitskaya (a16z bio deal team member and synthetic biology expert), discuss the results and implications three related articles co-published in Science, which all advance our understanding of a very unique kind of ...

This episode was recorded in March of 2019 to celebrate the 20th anniversary of Folding at Home, the distributed computing project for simulating protein dynamics, and originally aired on The a16z Podcast. Folding at Home is run on millions of devices, is the world’s largest supercomputer, and tackles some of biology’s toughest problems, including COVID-19.

Proteins are molecular machines that must first assemble themselves to funct...

On the path from scientific discovery to new drug, the clinical trial is a huge — and critical — hurdle. Clinical trials are themselves experiments, and to make sure that they are doing the best possible job at determining the safety and efficacy of the new drug, we need to be able to do experiments on those experiments. But how do you do that in such a highly regulated space? 

Host Lauren Richardson talks to James Zou, Assistant Pr...

They say you should never judge a book by its cover, but can you judge a cell by its shape? On this episode, host Lauren Richardson is joined by Maddison Masaeli (CEO and cofounder of Deepcell), and a16z general partner Vijay Pande (whose lab at Stanford focused on the development of novel computational methods for simulating biology), to discuss what we can learn by characterizing a  cell's shape — also known as its morphology...

Neuroscientists have long been trying to determine what happens in the brain during sleep, but to date, they have overlooked a key player: astrocytes. These star-shaped cells were once thought to be the glue that held the brain together, but we are now beginning to appreciate their importance in a variety of brain functions. In this episode, host Lauren Richardson talks to Kira Poskanzer, Assistant Professor at the University of Ca...

Today we are re-running an episode exploring a question that seems super straightforward, but that on closer examination reveals incredible complexity, and that is "how do we put the patient at the center of the healthcare system?” It almost seems counterintuitive, since aren’t patients always the center of healthcare? But healthcare is a strange industry, in that it is built with the fundamental goal of serving patients, but i...

In 1994, 29 bald eagles were found dead at DeGray Lake in Arkansas. This mass mortality event kicked off a search for the culprit which has last over 25 years. On this episode of the Bio Eats World Journal Club, host Lauren Richardson talks to Susan B. Wilde of the University of Georgia about her group's work finally identifying the eagle killer, and revealing a complex web of ecosystem dysfunction. Solving this mystery require...

Understanding how plants have adapted to natural climate change over millions of years provides a playbook of evolutionary strategies to help us prepare for and respond to man-made climate change. On this episode, host Lauren Richardson talks to Thomas Juenger, Associate Professor at the University of Texas in Austin and co-senior author of the recent article “Genomic mechanisms of climate adaptation in polyploid bioenergy switchgr...

The search for and conjecture about alien life has evolved, from science fiction to just plain science. On this episode, host Lauren Richardson talks to Arik Kershenbaum, Ph.D, author of the new book “The Zoologist’s Guide to the Galaxy: What Animals on Earth Reveal about Aliens — and Ourselves”, about what we can conjecture about alien life, based on the laws that govern life on Earth, and the universe at large. The conversation c...

Today we are re-running a previous episode of Journal Club — our show where we curate breakthrough research and bridge paper to practice — in light of a recent article published in the journal Nature (see show notes below). In this episode, host Lauren Richardson talks to Professor Anthony Atala from the Wake Forest School of Medicine about his lab’s work creating an engineered uterus that can support live births. This work represe...

Mosquitoes are the deadliest animals on Earth and for millennia humans have tried to rid themselves of these disease-spreading pests, with shockingly little success. On this episode of the Bio Eats World Journal Club, host Lauren Richardson talks to Leslie Vosshall of Rockefeller University about two articles from her lab investigating the neural and genetic basis of the mosquito's love for us and our blood. The conversation co...

In this episode, we talk with Jeff Hawkins—an entrepreneur and scientist, known for inventing some of the earliest handheld computers, the Palm and the Treo, who then turned his career to neuroscience and founded the Redwood Center for Theoretical Neuroscience in 2002 and Numenta in 2005—about a new theory about how the cells in our brain work to create intelligence. What exactly is happening in the neocortex as our brains process ...

In a healthy person, your body automatically adjusts blood pressure constantly, and this adjustment is governed by what’s called the baroreflex. However, a spinal cord injury can disrupt this reflex, which has both short term consequences, like passing out, but also long term consequences like an increased risk of heart disease and stroke. On this episode of the Bio Eats World Journal Club, host Lauren Richardson is joined by Dr. A...

Sea turtles occupy a very special biological niche in our world. And we still know relatively little about these creatures, one of the very few marine reptiles on the face of the planet. But as population growth and activity on coasts has exploded, so have our encounters with sea turtles... including, unfortunately, those that cause injury and disease. So what advances in technology and healthcare are helping us treat these incredi...

On this episode of the Bio Eats World Journal Club, we explore the very compelling question of whether we can use our understanding of developmental biology to create oocytes (aka eggs or female gametes) from stem cells in the lab. If possible, this could be on par with the development of in vitro fertilization in terms of extending fertility. But creating an oocyte from a stem cell has some unique and high-stakes challenges. Host ...

To date, synthetic biology has been mainly focused on reproducing existing compounds and materials with biomanufacturing. Think of engineering yeast to produce anti-malarial drugs, or bacteria producing spider silk. But as our guest — Professor Tom Ellis of Imperial College London — argues, the future of synthetic biology is in creating materials with fundamentally new and distinct functions. Imagine, a spider silk rope that it is ...
