CRISPR is a family of DNA sequences in bacteria and archaea that are a part of these organisms’ cellular defense system. A recent discovery showed how this mechanism can be used to edit genes much more easily than legacy methods. In this episode I chat with Sam Sternberg about the naturally occuring CRISPR systems, how they work, and how CRISPR together with its associated enzymes can be used to cut, and subsequently, edit, DNA. We conclude the episode with an outlook on the potential use in medicine.
Stem cells are an important part of today’s medical practice, and their importance will grow in the future based on research conducted today. One of the researchers in Derrick Rossi of Harvard and the Boston Children’s Hospital. In the episode we introduce the different kinds of stem cells and their role in the body and in medical treatments. We then discuss some clinical use cases as well as current research (in general and in Derrick’s group).
In this episode we discuss perception and perceptual systems with Wilson S. Geisler, who is the director of the Center for Perceptual Systems at UT Austin. We discuss perception in general and about approaches used in perception research including neuroscience and computation and modeling. We discuss in some detail Bill’s own field work work on vision and visual perception.
In this episode we talk to fellow podcasters Vincent Racaniello and Dickson Despommier about viruses, bacteria and other parasites. Among other topics we discuss what each kind of parasite is made of an how they interact with the human organism (in good and bad ways).
This episode is a conversation with NASA “space doctor” Jim Logan about space medicine and telemedicine. We start by defining the two concepts and how they relate. We then delve deeper into various specific medical issues in space (such as fluid shifts, bone mass loss and radiation). Next up is a discussion of the history of telemedicine and its relationship to space medicine, which leads us to looking astronauts can be treated for “normal” diseases from ground. We concluse the episode with an outlook on how telemedicine might develop in the future.
