Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• Stanford physicist Mahlet Shiferaw on Learning Cosmology from Galaxies — The Universe is shaped by an invisible “cosmic web” of dark matter that guides where galaxies form. By comparing observations of galaxies to predictions from models, we can probe the nature of dark matter and dark energy. Cosmologists are now developing new modeling and inference techniques to unlock even more information from upcoming galaxy surveys.
• Stanford biologist Sebastian Somolinos on Give Evolution a Chance — When was the last time you watched evolution happen? Evolution is nature’s most powerful problem solver, yet creatures like horseshoe crabs remind us that it can also be slow and stubbornly conservative. To unlock evolution’s full creative potential, and to appreciate evolution more fully, we must learn how to accelerate it. We need to give evolution a chance.

It’s an age-old question: How did life come about? Even the simplest creatures that exhibit the two hallmarks of life, namely metabolism and replication, are astoundingly complex. While the search for life’s origin has fascinated humans for centuries, recent breakthroughs point us in a more conclusive direction, and have remarkable implications. Among important side insights are the unexpected similarities between prebiotic and human innovation, and the central role that energy and information have played in transforming the planet over the last 4 billion years, leading right up to the present climate crisis.
Our Wonderfest speaker, Dr. Charles Marshall, is Distinguished Professor of Integrative Biology at UC Berkeley. He is also Director of the University of California Museum of Paleontology.

Dr. Vernard Lewis first encountered insects as a child, capturing grasshoppers and ants in California’s central valley. Since then, he has traveled to fifty countries to discuss many creepy-crawlies, sometimes as a member of the United Nations Global Termite Expert Group. This Wonderfest event offers a rather personal account of a bug-rich life, including oakworm adventures on Mt. Tamalpais, and (tiny) pest removal at San Quentin Prison. Dr. Lewis will share “field experiences” with termites, with bedbugs, with cockroaches, and with courtrooms (as an expert witness). He will also display real insects — both dead and alive — and the damage they can do.
Our Wonderfest speaker is Vernard Lewis, Cooperative Extension Specialist (emeritus) at UC Berkeley. Dr. Lewis has earned three degrees in entomology, and is a global authority on termites.

2025 marks the 100th anniversary of the “Trial of the Century”: Tennessee vs. John T. Scopes, the first major legal assault against the teaching of evolution in America. Mostly because of the fictional movie Inherit the Wind, the Scopes “monkey trial” is wrongly perceived as a victory for evolution over the forces of obscurantism. The full story is much more complex and interesting, involving science, religion, law, education, politics, celebrities, modern communications, and the politicization of science.
Our Wonderfest speaker is physical anthropologist Dr. Eugenie Scott, author of Evolution vs. Creationism: An Introduction, and former director of the National Center for Science Education. Genie is the recipient of numerous awards from both scientists and educators, including the National Academy of Sciences Public Welfare Medal.

Love may not “make the world go ’round,” but it surely makes the ride more joyous. The outward displays of love are familiar and simple: a reassuring touch, a passionate kiss, a bedtime story told to a drowsy child. But what is going on inside the brains of people in a loving relationship? Surprisingly, neuroscience can now inform us about the bonds of affection, and how, over each lifetime, love acts to sustain our body and even prolong our life.
Wonderfest’s speaker is psychologist Thomas B. Lewis, M.D., Adjunct Professor at the University of San Francisco and Asst. Clinical Professor of Psychiatry at UCSF. Dr. Lewis is co-author of A General Theory of Love.

Basic physics shapes the natural world. Through evolution, creatures have figured out how to use the laws of physics to make biology flourish. Flamingos generate water vortices to trap food. Various birds and fish use vortex shedding and fluid turbulence to control movement. For small animals, electrostatic forces and/or capillary forces can reign over gravity to affect the critters’ very survival. Nature is a beautiful dance of biology and physics.
Our speaker is biophysicist Victor M. Ortega Jiménez, Assistant Professor in the Integrative Biology Department at UC Berkeley. Dr. Ortega-Jiménez directs Cal’s Ornithopterus laboratory in organismal dynamics.

Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• Stanford computer scientist Nicole Meister on Has ChatGPT Memorized the Internet? — Large Language Models (LLMs), such as ChatGPT, have recently gained widespread popularity. Trained on vast amounts of internet data, these AI models raise important questions about the nature of their responses: are they truly synthesized or simply memorized? Researchers can statistically evaluate this claim to reveal test set contamination in LLMs.
• Stanford biologist Jenni Serrano Rojas on Unraveling Frogs’ Secrets for Conservation — Biotelemetry tools are revolutionizing our study of animals, from the largest to the tiniest species. They reveal hidden animal interactions, critical living spaces, and essential resources. In poison frogs, in particular, biotelemetry affords insights that inform conservation strategies and help the species to respond to global change.

Wonderfest Science Envoys are early-career researchers with enhanced communication skills and aspirations. Following short talks on provocative modern science topics, these two Science Envoys will answer questions with insight and enthusiasm:
• UC Berkeley astrophysicist Daniel Brethauer on Astronomically Rocking Out to Heavy Metals — The gold in jewelry, the uranium in a nuclear power plant, the caesium in atomic clocks: what do these all have in common? It turns out they were likely forged in the fires of a cosmic explosion known as a kilonova. These extremely energetic events reveal the origins of the periodic table’s heaviest elements.
• UC Berkeley ecologist Tyus Williams on Unraveling the Ecology of Domestic Cats — What if one of our greatest companions is potentially one of our greatest threats? When free to roam, domestic cats can severely disrupt wildlife communities. However, understanding cats’ behavior and how they’re influenced by their surroundings can allow us to develop better conservation strategies.

The words sex and gender challenge us, even scientifically. Sex commonly refers to a creature’s physical and biological characteristics. Gender refers to behavior and self-presentation within a social group. Since nature is replete with social groups, we can take rich delight in trying to understand gender diversity among animals. This is a key topic in the new book by Dr. Nathan Lents: The Sexual Evolution: How 500 Million Years of Sex, Gender, and Mating Shape Modern Relationships. Wonderfest joins the San Francisco Public Library to explore gender diversity in the animal kingdom.
Our speaker is Dr. Nathan Lents, Professor of Biology and Director of the Cell and Molecular Biology program at John Jay College, part of the City University of New York (CUNY). This event is co-presented by Wonderfest and the San Francisco Public Library.

We are members of the genus Homo, distinguished from other primates as bipedal great apes. So far, we have found fossil evidence for several other members of our genus, i.e., several other humans. How does a fossil gain entry into this exclusive club? How many members are there? What do we currently know about these possible relatives — and why aren’t they alive, today, walking upright among us?
Our speaker is biological anthropologist Julie Hui, Adjunct Professor at the College of Marin. Julie was — and is — a Wonderfest Science Envoy who takes science outreach seriously.

Over 20,000(!) species of mushroom-forming fungi support the health and diversity of multiple ecosystems. Technically, what are mushrooms? How do they live, and what are some of the myriad ways they disperse, reproduce, and (even) communicate? Perhaps most important, how can we use mushrooms to help feed humanity and heal the biosphere?
Our speaker is Dr. Dennis Desjardin, Professor Emeritus of Biology at San Francisco State University, and Director Emeritus of SFSU’s Thiers Herbarium. As the author of California Mushrooms and Chief Mycologist for Sempera Organics, Inc., Dr. Desjardin is known as the “Mushroom Guru of the West Coast.” This event is co-presented by Wonderfest and the San Francisco Public Library.

Science is for everyone, and benefits everyone. But American science is in deep trouble. In a podcast entitled Cuts to Science Funding and Why They Matter, physicist and author Sean Carroll thunders that recent presidential executive orders constitute “an absolutely devastating blow to the way science gets done in the United States.” On Friday afternoon, March 7th, Wonderfest joins thousands of the thoughtful to Stand Up for Science at San Francisco’s Civic Center Plaza. Please join us!
Stand Up for Science is a grassroots organization led by five early-career scientists — along with many volunteers (like us) — who work to protect the American science enterprise.
