Scientists usually study biology in animals such as lab rats, but their discoveries do not always translate between species. What if we could study human biology specifically? In this episode, we talk to Dr. Jurgen Knoblich and Dr. Zev Gartner about their efforts to create organoids, which are miniature, simplified versions of organs created from human cells. Using these organoids, Drs. Knoblich and Gartner can study how human organs develop and how they are affected by disease. How do they make these organoids, and what will organoids mean for our future health?
Have you ever spaced out while traveling somewhere but still made it to your desintation effortlessly? Our brain is amazing at calculating exactly where we are relative to things around us, but this is a skill we often take for granted. In this episode, Producer Sama Ahmed talks with Dr. Michael Yartsev about how we know where we are in the world, how we make memories, and how we make decisions. Dr. Yartsev is uncovering all of this utilizing a rather unconventional and totally awesome animal: the bat! This episode is a re-release of an episode from 2013.
In this episode we bring you short talks from ten young, passionate scientists eager to tell you about their cutting-edge discoveries. Each scientist is given just three minutes to launch their audience to new horizons and bring them back to earth, ready for the next exciting journey. Come with us as we explore new horizons in disease prevention, ways that our bodies could one day produce their own treatments, how scary spiders can actually help us reduce pain, and much, much more. Intrigued? Let's begin our countdown to science!
In this episode we’ll explore humanity’s, and the entire animal kingdom’s, fraught relationship with its closest biological cousins, fungi. We will hear about how we can’t live without them, how they’re trying to wipe us off the face of the planet, and how at least one company thinks they’re the key to changing how we view our own mortality.
This one of our largest single episodes, comprised of four parts!
First, Dr. Dennis Desjardin of San Francisco State University will tell us about his lifelong relationship with fungi and some of the bizarre organisms he has discovered. Next, we’ll talk to Dr. Margo Daub of North Carolina State University about a deadly pathogen that threatens our food security. Third, we will hear from Dr. Anita Sil of UCSF about a deadly fungus that uses our own immune system against us, and finally, Claire McNamara from the startup Coeio will explain how their product can leverage the power of fungi to create a radical shift in our view on death.
In this episode we bring back Professor Terrence Deacon, a biological anthropologist at the University of California, Berkeley, to talk about language. He tells us one possible story of how language first evolved, and why he believes language is a uniquely human capability. Listen to find out how language is about a lot more than just speech.
In Part 2 of “How to Build a Human”, we continue our investigation of our unique features that set us apart from other animals. We spoke to Dr. Nathan Young from the University of California San Francisco, who studies the development of the human skeleton and looks at how the variations in our skeletal structure have contributed to our evolution and the development of human civilization.
We humans like to think of ourselves as pretty different from other animals. Language, philosophy, art, technology - we do things it seems like no other animal is capable of. But what makes us this way? In part one of our investigation, we focus on two features of the brain that seem to be particular to people. We start with Arnold Kriegstein of the University of California, San Francisco, who studies a type of stem cell that does something special during human brain development. We then turn to Kira Poskanzer and Anna Molofsky, also of UCSF, who believe the secret to human-ness might lie with a totally different, often neglected kind of brain cell.
Science journalism generally focuses on new discoveries. But this leaves out a part of the process that will make or break you as a scientist: how do you come up with the right questions to ask in the first place? In today’s episode, we talk to Charles Zuker of Columbia University about this process. Listen to find out the two questions he asks to determine whether an experiment is worth doing.
Our ability to diagnose and treat disorders of the mind lags far behind other medical disciplines. For our latest episode, we talked to Dr. Matthew State about why this is the case, and discussed how his research into the genetics of autism is revealing promising paths to future treatments.
Ready to get blasted with science? We recorded five different PhD students as they summarized their entire thesis in 3 minutes or less. The challenge was to describe their research with as little jargon as possible, for a general audience. You’ll hear about everything from cancer, to the developing embryo, to how dieting might make you smarter.
