Greetings, fellow Group 14 travelers!
This week, we follow one thread through the cosmic tapestry: Silicon (Si). From the 'ghost sand' clogging our local turbines to the 'primal grit' forged in the first galaxies, Silicon is a paradox of materials science. The way we manage it determines whether it remains a hurdle to clear or becomes the backbone of the telescopes that let us see forever.
In Silicon Valley, we usually treat silicon as the hero—the “brain” in our semiconductors. But in our landfills and wastewater plants, it plays a villainous role in the form of Siloxanes. These are silicon-oxygen molecules (found in everything from shampoos to chip-manufacturing layers) that give products a silky feel.
When organic waste breaks down, these volatile siloxanes hitch a ride in the resulting biogas. When we try to burn that gas for renewable energy, the heat converts them into silicon dioxide (SiO2)—literally glass.
Imagine running a high-performance engine while a “ghost” slowly pours fine sand into the pistons. This “glassification” creates a hard white crust that destroys turbines and engines.
Locally, projects like the San Francisco’s Southeast Biogas Utilization Project are breaking ground to better refine these gases, showing that in the Bay Area, there are ongoing efforts to engineering our way from silicon waste to clean, sustainable power.
As we look toward Artemis, our focus shifts from silicon as a pollutant to silicon as a resource—though not without complexity. The Moon is essentially a giant silicon-rich ball of rock and glass.
The “Genesis” Rock: During the Apollo 15 mission, astronauts Irwin and Scott brought back the famous “Genesis Rock” (Sample 15415). It is composed almost entirely of Anorthosite, a silicate-rich rock that formed the Moon’s Highlands billions of years ago.
ISRU Engineering: To address the extreme cost of mass transport, researchers are investigating In-Situ Resource Utilization (ISRU). Lunar regolith is roughly 45% Oxygen and 21% Silicon by mass, making it a tempting reservoir. While laser-sintering aims to 3D-print structures from this dust, the physical reality of manipulating raw lunar silicon—characterized by its jagged, unweathered edges—remains a severe engineering risk to both equipment and environment.
The ethics of ISRU is one of the most debated topics in contemporary “soft law.” As we transition to a “settlement” era—marked by the 2026 expansion of the Artemis Accords to 61 signatory nations (with Oman joining this past January)—the question isn’t just if we can use lunar resources, but who has the right to them.
1. The Utilitarian Argument: Efficiency as a Virtue
From an engineering standpoint, ISRU is often framed as a necessary path for deep-space flight. Proponents argue it reduces the environmental tax of Earth-side launches and provides a “Lifeboat” safety margin by sourcing oxygen and propellant locally. In this view, the expansion of human presence takes precedence over the preservation of abiotic (non-living) rock.
2. The Legal & Equitable Dilemma: CHM vs. “First in Time”
The primary conflict lies in the tension between two historical doctrines:
Common Heritage of Mankind (CHM): Codified in the 1979 Moon Agreement, this principle argues that space resources belong to everyone. It builds on the 1967 Outer Space Treaty, which declared space the “province of all mankind.”
Operational Deconfliction: The Artemis Accords (2020) take a different tack. They rely on the 1967 Treaty to argue that while you cannot own the Moon, extraction is legal and does not constitute “national appropriation.”
The Ethical Risk: Critics, highlighted in the March 2026 Open Lunar report, worry that “Safety Zones” could lead to “de facto” land grabs. If a nation monopolizes a rare patch of water ice in a Permanently Shadowed Region (PSR), they haven’t technically “appropriated” the territory, but they have effectively monopolized a vital resource, potentially marginalizing nations that are not yet spacefaring.
Finally, we look beyond our solar system to the “primitive kitchen” of the early universe. In a massive recent find, the James Webb Space Telescope (JWST) looked at Sextans A, a tiny, metal-poor galaxy 4 million light-years away.
Standard models suggested these primitive galaxies couldn’t “bake” much dust. But JWST spotted the tell-tale signature of Silicon Carbide (SiC) being forged in the atmospheres of aging stars.
The Technical Handshake: The irony is sublime. While the JWST’s famous mirrors are gold-coated beryllium, they rely on a massive, ultra-rigid backbone—the Instrument Support Structure (ISS)—made of high-tech Silicon Carbide. We are using SiC technology in space to look back in time and discover where the first grains of SiC were born.
If you want to see these “Silicon-born” discoveries in high-definition, you won’t want to miss the legendary Alex Filippenko on Wednesday, April 29. He will be in the East Bay at the Orinda Theater to discuss the most exciting, late-breaking results from the JWST.
It is a fitting venue for a talk about our collective future; while we look at the universe through JWST, the Orinda ONE project is doing the “In-Situ” work here on Earth—uniting the community to enhance and preserve the heart of Orinda. Just as Artemis seeks to build a sustainable home on the Moon, Orinda ONE is a reminder that the best science happens when the community is aligned.
See you somewhere in the Si-Valley (or at the Orinda Theater!),

Why Study Insect Ecology in the Field? - 04/13/2026 12:00 PM
Sonoma State University - Biology Colloquium Rohnert Park
From Dr. Yang’s website: “...I am working to develop a temporally explicit view of ecology that examines how ecological communities combine complex, coordinated and changing interactions over time. I am particularly interested in the effects of climate change on species interactions, community responses to strong perturbation events, phenological cues and phenological shifts, and seasonal changes in the nature and outcomes of species interactions. I study several different organisms in a wide range of ecological communities, each of which contributes to a broader understanding of how species interactions change over time...”

Thinking with Things - 04/13/2026 12:30 PM
Computing and Data Science Building (CoDA) Stanford
As our tools grow more intimate and invasive, understanding the patterns at play when artifacts and minds interact has never been more urgent. We routinely underestimate what seem like minor details, yet subtle shifts dramatically alter what follows. Drawing on two decades of designing learning spaces and digital experiences, this talk explores how physical spaces, digital interfaces, and even the simplest everyday tools actively nudge our thinking and how we might intentionally design interactions to shape it for the better.
Speaker: Scott Doorley, Stanford University
Programmable quantum matter at the frontier of classical simulations - 04/13/2026 02:30 PM
Physics North Berkeley
Quantum computers have begun to achieve the scale and precision required to simulate condensed matter models in regimes that push the limits of classical supercomputers, offering a fully programmable platform for simulating quantum materials. This talk will explore recent experiments at the frontier of quantum advantage for simulating the dynamics of magnets and correlated electrons using Quantinuum’s latest generations of trapped-ion quantum processors.
Speaker: Andrew Potter, University of British Columbia
Statistical Structural Biology - 04/13/2026 04:00 PM
Grimes Engineering Center Berkeley
In a post-“AlphaFold has solved structure prediction” world, our lab is obsessed with the concept of statistical structural biology.First, we collect large datasets (X-ray fragment screens from 1000s of individual crystals) and use new statistical approaches to identify small molecule binders. This inspires new inhibitors, allosteric modulators, and enzyme design strategies. Second, we examine how experimental information in X-ray crystallography and CryoEM encodes statistical distributions of conformations. This inspires software (e.g. qFit) that reveals hidden conformations and new guidance frameworks for diffusion models. Our work reveals the extent of memorization in current models and suggests experiments to extract even more information for improved training. These two statistical approaches to structural biology are synergistic in examining many aspects of biological mechanism. A current focus is the promiscuity of ligand binding in drug metabolizing proteins, as part of the OpenADMET consortium.

New developments in quantum black hole - 04/13/2026 04:15 PM
Physics North Berkeley
How should we understand black holes at a quantum mechanical level? In the past years, we have made dramatic progress in answering this question, from a better understanding of how information can escape from a black hole to exact gravitational calculations of black hole entropies. In this talk, I will describe some of the advancements we have made in understanding black hole thermodynamics: I will describe how quantum gravity corrections drastically alter the physics of black holes at low temperatures, how such effects completely change the dynamical evolution of a single charged black hole when left alone to evaporate, and how, in special cases, we can now compute the entropy of black holes with arbitrary precision without relying on a UV completion of quantum gravity. Along the way, I will point out several parallels between phenomena that we have seen in the past century in atomic physics and novel effects that we can now explicitly compute for black holes.

Curating Investor Access to Cleantech 2.0 - 04/13/2026 04:30 PM
Hewlett Teaching Center Stanford
Disruptive forces of change such as urgent electricity demand, onshoring supply chains, and increased weather volatility are combining to create the biggest innovation wave in a generation: Cleantech 2.0. In the US, early-stage cleantech companies are emerging to address some of the biggest challenges facing businesses today. They use unprecedented tools and offer a leap of value, leading to increased profits, reduced risk and improved resilience.
Yet US early-stage cleantech is too often overlooked by investors. It is a complex, dynamic, and technical space. Assessing early-stage cleantech presents a challenge, and investors have limited access pathways that usually rely on picking individual funds and companies when predicting winners is daunting.
In this talk, Jane Woodward aims to demystify Cleantech 2.0- what drives it, what makes it enduring, and what these companies look like. This talk will also make the case for a strategic approach to bring investors into this space, using a hybrid portfolio structure designed to capture upside, mitigate downside, and provide early access to disruptive innovation.

Colliders in the Sky: Probing Fundamental Physics with Cosmological Data - 04/13/2026 04:30 PM
Stanford Linear Accelerator (SLAC) Colloquium Series Menlo Park
The first fractions of a second after the Big Bang likely involved physics operating at energy scales orders of magnitude above those accessible to terrestrial experiments. This epoch - known as inflation - played a crucial role in cosmic history, sourcing quantum fluctuations that seed structure formation in the late Universe. Despite its importance, the inflationary period is poorly understood, and little is known about its particle content or interactions. In this talk, I will describe how modern cosmological observations allow us to probe this ultra-high-energy regime by searching for subtle patterns in the distribution of cosmic microwave background radiation and galaxy positions. I will present recent results using observational data, highlighting how new techniques enable precision measurements of primordial particle physics, effectively turning the Universe into a “cosmic collider”. I will conclude by discussing how the next generation of survey data, if modeled precisely enough, could lead to significant advancements in our knowledge of the inflationary Universe.

Attempts to deliver on the promise of natural products - 04/14/2026 11:00 AM
Latimer Hall Berkeley
Natural product (NP) total synthesis involves experimental discovery and decision-making at every stage: why this route and not another? Why this intermediate and not its close analog? Why this NP, optimized for the producer organism’s survival in its ecological niche, and not a close analog, optimized for therapeutic use? The vast numbers of options surrounding all possible choices exceed human capacity for evaluation. Our group has begun to make these decisions with the aid of computation. These calculations, which contain numerous approximations, are not taken at face value, but instead subjected to experimental interrogation. If correct, however, computational predictions can greatly simplify our choice of reagent, choice of intermediate (subTGT), or even choice of NP target (TGT).

The Impact of Cellphone Bans in Schools on Student Outcomes: Evidence from Florida - Livestream - 04/14/2026 12:00 PM
Stanford University
Cellphone bans in schools have become a popular policy in recent years in the United States, yet very little is known about their effects on student outcomes. In this study, we try to fill this gap by examining the causal effects of bans on student test scores, suspensions, and absences using detailed student-level data from Florida and a quasi-experimental research strategy relying upon differences in pre-ban cellphone use by students, as measured by building-level Advan data. Several important findings emerge. First, we show that the enforcement of cellphone bans in schools led to a significant increase in student suspensions in the short-term, especially among Black students, but disciplinary actions began to dissipate after the first year, potentially suggesting a new steady state after an initial adjustment period. Second, we find significant improvements in student test scores in the second year of the ban after that initial adjustment period. Third, the findings suggest that cellphone bans in schools significantly reduce student unexcused absences, an effect that may explain a large fraction of the test score gains. The effects of cellphone bans are more pronounced in middle and high school settings where student smartphone ownership is more common.

Two Targets, One Parasite: Designing Selective Covalent Inhibitors for Chagas Disease - 04/14/2026 02:00 PM
Tan Hall Berkeley
Chagas Disease, caused by the protozoan parasite Trypanosoma cruzi, affects millions worldwide, yet current therapies suffer from limited efficacy, long treatment duration, and poor tolerability. Two complementary discovery strategies, one mechanism - driven and one phenotypically guided, were explored toward safer, shorter-course treatments. Covalent picolinamides were developed as highly selective inhibitors of the essential T. cruzi kinase CLK1, achieving potent cellular activity and cures in mouse infections models. In parallel, covalent cyanotriazoles were optimized into IID432, a selective T. cruzi topoisomerase II poison capable of delivering an unprecedented single-dose cure in vivo and now advancing toward clinical evaluation. Together, these strategies illustrate how mechanistic insight and covalent design can enable next-generation therapies for Chagas Disease.

How Might Quantum Platforms Reshape Many-Body Physics? - 04/14/2026 03:30 PM
Hewlett Teaching Center Stanford
Quantum platforms are approaching a scale at which they will enable the realization of a vast number of quantum circuits. Some of these will solve computational problems of interest to industry and commerce; others will address longstanding questions about quantum systems; and still others will vindicate Wigner and Dyson. Yet even this will leave ample room for posing entirely new questions about many-body quantum systems.In this talk, I will describe two possibilities. The first is a concrete proposal: defining and studying quantum games of various kinds. The second is a broader vision: using quantum platforms in a “discovery mode,” analogous to the role particle accelerators have played in uncovering new particle physics.

SLAC on Tap: Atoms in slow motion, the skyrmion, and crackling magnets: the hidden world of quantum materials - 04/14/2026 05:30 PM
The Dutch Goose Menlo Park
What do the sound of Rice Krispies and the motion of atoms and magnets have in common? SLAC scientist Joshua Turner will take us inside the hidden world of quantum materials; he will show how watching atoms in slow motion can tell us about exotic phases of matter such as high-temperature superconductivity, how tracking the way electrons spin can reveal new types of particles, and what “listening” to the chaotic motion of atoms and magnets can tell us about the properties of matter itself. Stick around after the talk for trivia, giveaways, a live cereal sound check, and the chance to create some chaotic motion of your own with a coordinated dance break.
Building California’s First Statewide Breeding Bird Atlas - 04/14/2026 06:00 PM
Hopkins Marine Station Pacific Grove
Join Van Pierszalowskifor an overview of the California Bird Atlas project, one of the most ambitious community-driven research efforts ever undertaken in the state. While 44 states have already completed a statewide breeding bird atlas, California has long been an outlier. That is now changing.
The Atlas officially launched in January 2026 and will document the breeding distribution and behavior of every bird species across California during a five-year field period (2026 - 2030). Organized by the nonprofit California Bird Atlas in collaboration with partners statewide, including Monterey Audubon Society, this talk will explain how the project works, how birders of all experience levels can participate, and share an early status update from the first months of fieldwork.

Wonderfest: Ask a Science Envoy: Cosmology & Evolution - 04/14/2026 07:00 PM
Hopmonk Tavern Novato
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.

From Watershed to Whales: Tracking the source and transport of microplastics in the greater Monterey Bay region - 04/15/2026 12:00 PM
Earth and Marine Sciences Building Santa Cruz
Plastic pollution is one of the defining environmental challenges of the 21st century. Microplastics are now pervasive throughout marine ecosystems, yet the pathways by which they move from land into coastal food webs remain poorly understood. From 2023-2025, our team conducted a comprehensive regional assessment of microplastics across the river-ocean continuum of central California. We sampled four major rivers, beach sands, coastal seawater, and key marine organisms including forage fish, krill, and blue whales. Processing more than 15,000 liters of water and 1,500 liters of sand yielded 25,000 microplastic particles as confirmed by uFTIR. While uFTIR analysis confirmed over two dozen polymer types in these particles, 94% were, polystyrene, polyethylene, polyamides, and polyester. Microplastic concentrations in river water declined across sampling events spanning before, during, and after high-flow periods, consistent with rapid downstream export and deposition of microplastics in the coastal ocean. Beaches emerged as major accumulation zones, with concentrations roughly thirty times higher than adjacent waters. Fibers, often blue and consistent with textile-derived microfibers, dominated larger particle classes, while polystyrene foam fragments suggest local consumer sources. Early biological analyses indicate that microplastics are reaching upper levels of the marine food web, including blue whales. Together, these findings provide the first source-to-sea baseline for microplastics in central California and reveal how human activity and environmental transport processes structure exposure across ecosystems, from rivers to the largest animals on Earth.

Probing Jupiter’s Moon Io for a Magma Ocean - 04/15/2026 12:30 PM
Mitchell Earth Sciences Building (04-560) Stanford
Io’s extensive volcanism was predicted in 1979 as a consequence of Europa and Ganymede’s gravitational influence on Io’s orbit around Jupiter. Less than a week later, this was confirmed by Voyager 1 observations of volcanic plumes on Io’s surface. Decades later, the Galileo spacecraft (named for Io’s discoverer) observed magnetic field variations that hinted a global magma ocean may be swirling beneath Io’s surface. Following tradition, I raced to predict if Juno flybys of Io would reveal another signature of a magma ocean from gravity field measurements. In this seminar, I will cover both the geophysical theory used to make my prediction and the spacecraft observational techniques that were needed to confirm it.

‘Cultivating Sustainable Sovereignty: Palestinian Agrarian Lives in Transnational Focus’ - 04/15/2026 03:30 PM
McCone Hall Berkeley
This talk will share a chapter from my first book project, Cultivating Sustainable Sovereignty: Palestinian Agrarian Lives in Transnational Focus. How have Palestinian agro-ecological and food systems changed due to settler colonialism over time? How do Palestinians’ agricultural practices and relationships - their food sovereignty efforts - serve their struggles for cultural and political sovereignty? Finally, how has the struggle for Palestinian food sovereignty turned global? I argue that Palestinian farmers in the northern West Bank use sustainable development to remain on their lands, but that doing so requires them to engage in the booms and busts of global capital. Furthermore, I detail how Israel uses agricultural science and the law to claim Palestinian farmers as naturally part of the environment and inferior cultivators - thus justifying their expulsion. I trace how such rhetoric by Israel and its supporters changed from the 20th century Green Revolution primacy of technoscientific dominance over “traditional” Palestinian agriculture, to the 21st century extolling of Jewish agricultural practices as authentic to the land and therefore, environmentally friendly. Finally, I demonstrate that Palestinian Americans’ engagement with practices of food sovereignty outside of Palestine is part of a transnational project of stewarding and protecting traditional Palestinian crops and foods that are under threat within Palestine under the hopes of returning the plants - and people - to the land someday. In both Palestine and the diaspora, Palestinians demonstrate creative methods to maintain and transmit cultural food knowledge across generations in the face of political and environmental threats to their livelihoods.

Can AI assist in Mathematics and Computer Science research? - 04/15/2026 04:00 PM
Sutardja Dai Hall Berkeley
We share our experience using LLMs to obtain new results in mathematics and computer science. We begin with an illustrative example from load-balancing in planet-scale cloud systems, outlining the abilities and limitations of LLMs. Next, we describe our experience with AlphaEvolve, an evolutionary language model from Google DeepMind, to establish new results in the approximability of the Traveling Salesman Problem (TSP), and MAX-CUT problem. We also derive new bounds for several Ramsey numbers. Our methodology entails evolving fleets of Python programs that generate proof chunks to yield these results, and to accelerate proof verification by up to 10,000x. We suggest that our results on inapproximability and Ramsey theory could not have been discovered by hand, and conclude with reflections on the state and promise of AI in mathematics and CS research.

Dark Matter and Black Holes - SOLD OUT - 04/15/2026 07:00 PM
Planted SF San Francisco
Everything we can see - stars, planets, galaxies, and even ourselves - makes up only a small fraction of the cosmos. The rest appears to be dominated by mysterious forces we cannot directly observe.
In this mind-bending lecture, Stefano Profumo, Professor of Physics at the University of California, Santa Cruz, explores two of the greatest mysteries in modern astrophysics: dark matter and black holes. Dark matter acts as the unseen scaffolding holding galaxies together, yet scientists still don’t know what it actually is. Black holes, meanwhile, are regions where gravity becomes so extreme that not even light can escape - and where the laws of physics begin to break down.
Drawing on research in particle physics and cosmology, Profumo unpacks what scientists know, what remains deeply puzzling, and why these two cosmic mysteries may be more connected than they first appear.

Decoding marine physiological mechanisms to build biotechnological resilience - 04/16/2026 12:30 PM
Valley Life Sciences Building Berkeley
Cutting-edge biotechnological innovations and transdisciplinary approaches have opened the door for deep understanding of physiological activities within marine organisms. These tools and approaches facilitate integrated studies of complex endogenous processes, such as immunological responses, metabolic pathway perturbations, and mechanisms that underpin survival and resilience in the face of unprecedented global change effects.
Multi-omics approaches are now being used routinely to investigate genotype to phenotype research questions in organisms exposed to a range of environmental conditions, such as increasing ocean temperatures and pathogen loads. Of particular importance is the area of biomarker discovery for early diagnostics of health, nutritional improvements, growth enhancement and production success in fisheries and aquaculture. Integrating these new advances with ground-truthedtraditional techniques may give us the best chance to understand and respond to current and future global environmental challenges:
How does an organism respond to stressors (e.g., diseases,pollutants, temperature, acidification) and their cumulative effects?
What are the tipping points for populations facing increased stress frequencies and magnitudes? Can these be predicted?
Can we add resilience and future-proof our commercially important marine populations and preserve those which areecologically sensitive?
As scientists, we have much to do…!

Despite the increasing availability of climate data, there is a significant gap between the production of scientific information and its practical use within planning and decision-making. Over the past two decades, climate services - decision-support processes and tools - have been developed at this interface to transform climate data into usable information. This talk will examine three key elements of climate services: the production of foundational climate datasets, the co-production of a climate services platform for the state of California, and a framework to more effectively bridge gaps between science, policy, and practice at state-levels.

Hydrogen Fuel and Fuel Cells for Sustainable and Environmentally-Friendly Power Generation - 04/16/2026 04:00 PM
Sonoma State Dept. of Engineering Science Rohnert Park
Recent developments in hydrogen production from renewable energies and fuel cell (FC) technologies have increased interest in their application toward sustainable and emission-free electricity generation. In addition to the fuel-to-electricity conversion advantages of FCs over conventional generation methods, their heat exhaust can also be recovered for combined heat and power (CHP) operations to improve their overall system efficiency. Furthermore, exciting achievements have been made in fuel-cell-powered passenger vehicles, heavy-duty trucks, and off-road vehicles. This presentation will cover hydrogen production from renewable energies, the use of hydrogen fuel for FC-based electricity production, and for transport technologies.

Multimode superconducting circuits for quantum information science - 04/16/2026 04:00 PM
Sonoma State Dept. of Engineering Science Rohnert Park
Superconducting circuits support quantum degrees of freedom that can be used to encode quantum bits. These superconducting qubits are a leading quantum information technology, but they are plagued by errors when performing multi-qubit conditional operations. One alternative is to make multi-mode circuits where multi-qubit operations are natural. I will introduce superconducting qubits and then explain our recent results on the trimon, a circuit that implements 3 qubit modes that all resemble transmon qubits. Strong dispersive couplings between the modes made a 3-qubit conditional gate the primitive operation. I will show how combining multiple drive tones allows us to remove conditionality at will and drive “forbidden” transitions, achieving complete control of a 2-qubit Hamiltonian. I will discuss prospects for deploying the trimon in large processor architectures.

A Field Guide to Spotting Misinformation - Livestream - 04/16/2026 04:00 PM
Skeptical Inquirer
For most of human history, survival depended on two things: group loyalty and split-second decisions. Today, those same ancient instincts are plugged into a network of billions of strangers and an endless stream of content. Deception is a universal survival strategy in nature; by understanding how the rapid pace of technology has outpaced our evolved defenses, we can see misinformation not as a personal failure, but as a biological challenge.
Drawing on her upcoming book, A Field Guide to Spotting Misinformation, Trecek-King places our modern misinformation crisis into a biological and historical context. She’ll explore how our ancient hardware makes us vulnerable and provides the practical tools we need to navigate the digital age without getting played.

Ecology of the Shasta-Trinity National Forest: How the Interrelationships between Flora, Fauna and Funga form the largest forest in California - 04/16/2026 05:45 PM
Sebastopol Grange Sebastopol
Mikhael found himself out of work last year due to health issues and chose to travel to Mt. Shasta for 6 weeks. While there, he studied everything he came across, from the ground to the sky. Waking to the sounds of chipmunks chittering as they chased each other up the trees, then delving deeper into the woods to see what should present itself, he followed the various mushrooms up in elevation through the months. He came upon many different biomes, each with their different communities of plants and animals and fungi! Come explore some of the interrelationships between these multitudinous kingdoms of life.

Starfish and the Unexpected Outcomes of Evolution - 04/16/2026 07:00 PM
Decentered Arts Studio San Francisco
With five arms, no clear front or back, and no obvious head, starfish break many of the rules we expect animals to follow. So how did such unusual symmetry evolve - and what happened to the head?
In this fascinating lecture, marine biologist Chris Lowe, Professor of Biology at Stanford University and researcher at Stanford’s Hopkins Marine Station in Monterey, explores a surprising discovery: starfish may actually be built almost entirely from the genetic program that forms the head in other animals.
By studying the genes that shape animal bodies during development, Lowe reveals how evolution transformed a typical bilateral animal into one of the ocean’s strangest creatures - and why starfish might be, genetically speaking, almost all head.
Nerd Nite SF #159: Karaoke, Naval Misadventures, and Wild Fermentation - 04/16/2026 07:00 PM
Rickshaw Stop San Francisco
Ready for another good, old-fashioned, classic Nerd Nite SF? We’re back at it again at the Rickshaw and ready to rumble! It’s been fun experimenting with format and location for our first few shows of the year, but you just can’t beat a classic Nerd Night show: We’ve got talks about the art and philosophy of karaoke, the not-so-human origins of the very human love for booze, and a howling history of the unluckiest ship to ever sail under the US flag.
Life, Love, Death, and the Other Self of Karaoke
By: Benjamin Poynter
A talk chronicling data and studies behind real-life excursions into the activity of karaoke across Los Angeles and the cities of Japan. After a certain point, when does the regular self transform into the ‘other’ self when participating in karaoke nights long enough, and what are the parallels, constructive or destructive, between those two selves that reveal themselves? Karaoke is a pastime that has moved beyond a fun, nighttime affair into a form in which people rely on it as a means of expressing and confessing what they normally cannot in daily life. Out of that, tales of love, lifelong friendship, tragedy, inventions, and even language study have come out of the speaker’s excursions. This talk is paired with an ongoing project where 125+ Japanese songs have been performed publicly as a means of studying the language and a special, interactive game, which is now in development out of those experiences.

Wild Fermentation, The Chimpanzee Diet & The Origins of Alcohol Production
By: Aleksey Maro
Why are humans attracted to alcohol? The answer might be buried in the fruit-filled diet of our early ancestors. Following the ‘Drunken Monkey’ hypothesis, Aleksey measured the alcohol content in fruits eaten by our nearest relatives - chimpanzees - and found they’re essentially knocking back 1 - 2 drinks a day. Join us as we track the evolutionary trail from fermented forest fruit to the mysterious origins of that which has brought us here today (beer).
The Invasive Spartina Project and Rails- Livestream - 04/16/2026 07:00 PM
Golden Gate Bird Alliance
The Invasive Spartina Project (ISP) is tasked with removing invasive Spartina species to restoring native habitat in SF Bay and protect our newly restored tidal wetlands. Tall, dense, and fast-growing, hybrid Spartina outcompetes other marsh species, overrunning wetlands and mudflats. Infestation reduces shorebird habitat but also provides cover for secretive marsh birds, including endangered California Ridgway’s Rails (RIRA). From 2005-2025, hybrid Spartina was reduced from 805 to 18 net acres, a reduction of over 97%. We also actively enhance habitat, including planting over 650,000 natives to provide cover for rails at over 40 sites. In 2027, we plan to begin our restoration work in San Leandro Bay, including at Arrowhead Marsh. This talk will cover what we have achieved so far and our plans for the future.

Autonomous Vehicles & the City: Policy, Deployment and Ecosystem Leadership - 04/17/2026 12:00 PM
Commonwealth Club San Francisco
As autonomous vehicle technology reaches maturation, the most urgent challenges are no longer just technical - they are civic and systemic.
The 2026 Autonomous Vehicles and the City Symposium marks our 10th anniversary, and goes “Beyond the Tech” to focus on building a robust automation ecosystem that works for people and cities alike. From AI perception and roadway safety to manufacturing friction, regulatory clarity, curb and edge management, and seamless integration with public transit, this year’s convening examines how automation can reduce collisions, advance Vision Zero goals, and expand mobility choice.
Featuring leading policymakers, regulators, OEMs, researchers, and innovators - and a joint USF - UC Berkeley PATH Demo Day - this two-day event tackles what it truly takes to move automation from breakthrough technology to sustainable urban system.

Breaking it and fixing it: new chemistry with nitrogen - 04/17/2026 04:00 PM
Latimer Hall Berkeley
Atmospheric N2 is a cheap, abundant resource with great potential for energy storage and chemical synthesis, but it is difficult to convert it into other compounds (“fixing” nitrogen). This seminar will describe some challenges and opportunities of nitrogen fixation, as well as my students’ discoveries of how to break the N-N bond of N2 using homogeneous transition-metal complexes. More recently, we have identified a new mechanism for sequential C-H activation and N-N activation to create C-N bonds. Detailed mechanistic studies reveal a cyclic reaction, which gives a route from atmospheric N2 and petroleum-derived arenes to substituted anilines. This is an important step toward preparing useful chemicals using air as a starting material.

30 Years of Exoplanet Discovery - 04/19/2026 10:00 AM
College Nine, Lewis Multipurpose Room Santa Cruz
NASA’s Kepler mission confirmed the discovery of its first rocky planet, named Kepler-10b. Measuring 1.4 times the size of Earth, it is the smallest planet ever discovered outside our solar system.The discovery of this so-called exoplanet is based on more than eight months of data collected by the spacecraft from May 2009 to early January 2010.
“All of Kepler’s best capabilities have converged to yield the first solid evidence of a rocky planet orbiting a star other than our sun,” said Natalie Batalha, Kepler’s deputy science team lead at NASA’s Ames Research Center in Moffett Field, Calif., and primary author of a paper on the discovery accepted by the Astrophysical Journal. “The Kepler team made a commitment in 2010 about finding the telltale signatures of small planets in the data, and it’s beginning to pay off.”
Kepler’s ultra-precise photometer measures the tiny decrease in a star’s brightness that occurs when a planet crosses in front of it. The size of the planet can be derived from these periodic dips in brightness. The distance between the planet and the star is calculated by measuring the time between successive dips as the planet orbits the star.
Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone, the region in a planetary system where liquid water can exist on the planet’s surface. However, since it orbits once every 0.84 days, Kepler-10b is more than 20 times closer to its star than Mercury is to our sun and not in the habitable zone.

‘Climate Wayfinding’ - 04/19/2026 02:00 PM
Manny’s San Francisco
Join us for readings and a conversation about Dr. Wilkinson’s new book, Climate Wayfinding.
As climate disruption reshapes landscapes, politics, and daily life, a deeper question lingers beneath the headlines: How do we live - fully, honestly, boldly - within this moment? Where do we turn for steadiness and imagination as we find our way forward?
Join climate leader Dr. Katharine K. Wilkinson (co-editor of All We Can Save) and celebrated poet Jane Hirshfield for readings and a conversation about Dr. Wilkinson’s new book, Climate Wayfinding. Together, they will explore how we orient ourselves within a changing world and what poetry can offer those of us seeking courage, clarity, and pathways to contribution.
Whether you are steeped in climate work or newly curious, whether poetry is a familiar companion or something you rarely encounter, you’ll leave this conversation feeling nourished, grounded, and more equipped for the journey ahead.
