Maria Barna is an authority on ribosomes – “life’s most ancient and spectacular molecular machines.” Ribosomes make proteins in the body. There can be a thousand different types of ribosomes in a single cell, she says, each with a specific job to do. But sometimes things go awry and ribosomes get “hijacked,” leading to disease. Barna studies these “diabolical” variations to find new therapies to treat diseases ranging from cancer and COVID to Parkinson’s. When diseases hit, it’s all about the ribosomes, Barna tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

In October, chemical engineer Will Tarpeh was awarded a 2025 MacArthur “Genius Grant” in recognition of his pioneering work to turn wastewater into a source of valuable materials. Will envisions a future in which the concept of wastewater is obsolete, thanks to advances in recycling. A couple of years ago, we sat down to talk with him about this work, and we hope you’ll take another listen today to learn more about the research Will is doing to transform the potential of wastewater into resources.

Gabriel Weintraub studies how digital markets evolve. In that regard, he says platforms like Amazon, Uber, and Airbnb have already disrupted multiple verticals through their use of data and digital technologies. Now, they face both the opportunity and the challenge of leveraging AI to further transform markets, while doing so in a responsible and accountable way. Weintraub is also applying these insights to ease friction and accelerate results in government procurement and regulation. Ultimately, we must fall in love with solving the problem, not with the technology itself, Weintraub tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Biochemist Lingyin Li survived breast cancer at just 30 and now works to harness the human immune system to fight cancers that have long evaded treatment. T cells, she says, are powerful cancer killers, but they can be oblivious. She and her lab colleagues have discovered a masking enzyme that squelches the immune system’s “danger signals” and are now developing drugs to block that enzyme. She likens her work to an arms race between cancer and immunotherapy. “The cancers are not getting smarter, but we are,” Li tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

About a year ago, a research team at Stanford Engineering led by Guosong Hong published a paper about their work to use a common food dye to make mouse skin transparent. Their findings made a big splash and have the potential to provide a range of benefits in health care. You can imagine that if we have the ability to see what’s going on under the skin without having to cut into it, or use radiation to get a clear look, this could improve everything from invasive biopsies to painful blood draws. We hope you’ll tune in again and enjoy.

Clinician-scientist Jill Helms is an expert on healing. Until about age 30, people heal easily, she says, but later on, not so well. Regenerative medicine suggests avenues for improvement, she promises. Her research focuses on understanding the physical and molecular processes of healing to design better therapies. One approach awakens “sleeper” stem cells to aid healing, a new drug in trial regenerates bone, and another avenue targets infections that appear near medical devices using gum-like tissues that create sealing barriers. In many ways, nature remains our best model for healing, Helms tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Bioengineer Michael Fischbach studies alternative vaccine delivery methods, like self-administered creams with no needles, health professionals, or side effects. He teases a day when vaccines that don’t make you feel bad come in the mail in ketchup-style packets. Such innovations would greatly improve vaccine uptake, especially in developing countries, and speed global response to novel viruses. It would change how we think about vaccines, Fischbach tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

As fall arrives, many regions experience dramatic weather shifts—think early frosts, storms, or unusual temperature swings. Last year, we sat down with Noah Diffenbaugh, an expert on climate change. We discussed the fact that extreme weather is becoming more frequent. Noah pointed out that there are still things we can do to mitigate the impacts of severe weather. We hope you’ll take another listen to this episode to learn about the solutions that are within reach.

Rishee Jain is an engineer and an expert in the built environment – the manmade structures of modern life. The future, Jain says, will be a place where everyone has a safe, comfortable place to live and work, and the built environment adapts in real time to our needs. Jain is now exploring cool roofs that reflect heat to lower indoor temperatures and improve occupants’ well-being. We once believed that humans bent infrastructure to our needs, but now we understand how infrastructure changes us, too, Jain tells host Russ Altman on this episode of Stanford Engineering’sThe Future of Everything podcast.
