Food security expert David Lobell is immersed in the data of agriculture. He uses satellite imagery, yield data, and advanced computational modeling to analyze the roughly 500 million farms worldwide to increase productivity and ensure global food security – now and in the future. Though food is often taken for granted, feeding a hungry world is our greatest environmental challenge, he says. Lobell goes on to explain how data can do much more than increase yields – it also cuts costs, prevents conflicts, reduces emissions and deforestation, and improves nutrition. Smart farming is key to food security and avoiding the problems that stem from hunger, Lobell tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Fungi are “nature’s biological recycling machines,” says guest Vayu Hill-Maini, a former chef turned bioengineer. That is, they take waste and turn it into good things. Hill-Maini now melds his scientific and culinary skills to create new foods, but also medicines, faux leather, pigments and other valuable products from mushrooms and molds. He uses CRISPR gene editing technology to “domesticate” these fungi – removing off-flavors and increasing nutritional content to make new-age cheeses, burgers, salami, and more. “We call it the DBTL cycle – design, build, taste, learn,” Hill-Maini tells host Russ Altman about his creative process on this episode of Stanford Engineering’s The Future of Everything podcast.

In the dotcom era, communication professor Angèle Christin embedded herself in newsrooms, where she witnessed how audience metrics tilted journalism toward viral content over in-depth reporting. Christin now researches the influencer economy and how content creators monetize their production by any of three means – brand sponsorships, engagement-based payments from social media platforms, and direct-to-audience subscriptions, donations, or sales. She says this engagement-based ecosystem steers communication toward what captures attention, not always what best informs. To improve our reeling national dialogue, we must first change the financial model of social media content, Christin tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Earlier this year, we got to witness the incredible launch and return of Artemis II, a NASA mission meant to lay the groundwork for a future lunar landing. Among the many accomplishments of the Artemis II mission, the crew successfully gathered real-time observations of the Moon that will contribute to our increased understanding of the cosmos. If you were inspired the same way we were, we thought it would be an opportune time to re-share an episode we recorded with astrophysicist Risa Wechsler on the future of the universe. We hope you’ll take another listen and that this episode will help you tap into more of that wonder the Artemis II crew sparked.

Michael Jewett is a pioneer of cell-free biotechnology. Instead of using living microbes as factories, he uses their internal molecular machinery to make valuable proteins, medicines, diagnostics, and other chemicals. Jewett recently used the technique for vaccine production in an approach that could produce up to 150,000 doses from one liter. He believes cell-free biotech could democratize the production of essential medicines, improve water safety, and help convert atmospheric carbon into useful products, among other promising possibilities. “It’s just-add-water biotechnology,” Jewett tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Computer scientist Keith Winstein is an expert in how computers communicate. Computer networks create what he calls shared fictions – abstract realities, like a website or a Zoom call, that exist only because the computers on either end agree to act as if they are real. Unfortunately, today’s networks lack a shared notion of a “computation,” which hurts market efficiency in cloud computing and frustrates efforts to hold tech companies accountable for the results of their algorithms. As computational power becomes concentrated in a smaller number of companies, Winstein advocates for a shared language of “computational truths,” defining computations precisely so results are reproducible and auditable. His research group hopes this will lead to greater transparency and accountability in the cloud and, ultimately, to greater confidence in the computations that companies do every day on our behalf. The truth matters, Winstein tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Candace Thille is an authority in learning science, educational technology, and AI-enabled learning environments. She is closing the two-way gap between the science of learning research and the hands-on practice of instruction to help students learn better. Timely and targeted feedback with the opportunity to apply that feedback is critical to learning, Thille says, and this is an area where AI supporting humans excels. She imagines a day in the not-too-distant future when human educators and AI-enabled assistants unite to help students learn faster and better than ever before. Learning is not a spectator sport, and AI can help us engage with learners – and educators – in new ways, Thille tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Legal expert Richard Ford studies the intersection of dress codes and the law. Clothing and hairstyles communicate power, identity, and social status, he says. Legal restrictions on dress stretch at least to the Middle Ages when “sumptuary laws” stipulated what one could wear by rank. Today, written rules have given way to unwritten codes that are in many ways more powerful culturally. Fashion is not trivial, he says, and no less worthy of study than high art or music. Clothing shapes everything, Ford tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.

Epidemiologist Yvonne “Bonnie” Maldonado is an expert in vaccine research and public health. Look back centuries, and the story is always the same, she says: Death rates from viruses have plummeted, especially in children and the elderly. And yet, millions of children die each year from vaccine-preventable diseases. Vaccines need a return of public confidence, and that starts with better messaging and greater support of nongovernmental messengers like herself. The bottom line is that vaccines are safe, she says. Vaccines work and we have saved many lives because of them, Maldonado reminds host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
