California Is a Nobel Powerhouse

Would you support us? Just a few bucks. We’d appreciate it!

You can keep your Oscars, Emmys, Grammys, and Tonys. Take your Pulitzers, Bookers, and Peabodys, too. Even the Pritzker and the Fields Medal don’t quite measure up. For me, nothing competes with the Nobel Prize as a symbol that someone has truly changed the world.

I’m not a scientist, but my mind lives in that space. Science, more than anything else, runs the world and reshapes it. This newsletter was born out of my fascination with how things work and the quiet mechanics behind the visible world and my love for all that California has to offer in the way of innovation and natural beauty. I love standing in front of something familiar and asking: why? how? what exactly is going on here? And nothing satisfies that intense curiosity more than science.

That said, I’ve never loved the word science. It feels cold and sometimes intimidating, as if it applies to people in lab coats and not to everyone else. I kinda wish there were a better word for that spirit of discovery that lives in all of us. Maybe it’s wonder. Maybe curiosity. I dunno. “Science” turns people off sometimes, unfortunately.

Whatever you call it, the Nobel Prize represents the highest acknowledgment of that pursuit. It is the world’s way of saying: this mattered. This changed something. And there are few places (if any) on Earth that can rival California when it comes to the number of people who have earned that honor.

This year, 2025, was no different. Three of the Nobel Prizes announced this week carried California fingerprints, adding to a tradition that stretches back more than a century.

The Nobel Prize in Physiology or Medicine came first. It went to Mary Brunkow, Shimon Sakaguchi, and Fred Ramsdell, the last of whom studied at UCLA and UC San Diego. (In epic California fashion, Ramsdell, who studied at UCLA and UC San Diego, didn’t even learn he’d become a Nobel laureate until after returning from a trip deep into the Wyoming wilderness, where he’d been out of contact with the outside world. What’s more Californian than that?) Their research on regulatory T cells explained how the immune system knows when to attack and when to stand down. Ramsdell’s discovery of a key gene that controls these cells has transformed how scientists think about autoimmune disease and organ transplantation.

Next came the Nobel Prize in Physics, awarded to John Clarke of UC Berkeley, Michel H. Devoret of UC Santa Barbara and Yale, and John M. Martinis of UC Santa Barbara (big shout out to UCSB!). Their award honored pioneering work that revealed how the strange laws of quantum mechanics can be seen in circuits large enough to hold in your hand. Beginning in Clarke’s Berkeley lab in the 1980s, the trio built superconducting loops that behaved like subatomic particles, “tunneling” and flipping between quantum energy states. Those experiments helped create the foundation for today’s quantum computers.

The Chemistry Prize followed a day later, shared by Susumu Kitagawa, Richard Robson, and Omar M. Yaghi of UC Berkeley for discoveries in metal–organic frameworks, or MOFs. These are crystalline materials so porous that a single gram can hold an entire roomful of gas (mind blown). MOFs are now used to capture carbon dioxide, filter water, and even pull drinking water from desert air. Yaghi’s Berkeley lab coined the term “reticular chemistry” to describe this new molecular architecture. His work has become one of California’s most important contributions to the climate sciences.

Those three announcements in as many days lit up California’s scientific community, has garnered many headlines and carried on a tradition that has made the state one of the world’s most reliable engines of Nobel-level discovery.

The University of California system now counts 74 Nobel Prizes among its faculty and researchers. 23 in physics and 16 in chemistry. Berkeley leads the list, with 26 laureates, followed by UC San Diego, UCLA, UC Santa Barbara, and UC San Francisco. Even smaller campuses, such as UC Riverside, have ties to winners like Barry Barish, who shared the 2017 Nobel in Physics for detecting gravitational waves.

Caltech, which I have written about extensively and is quite close to my own home, counts 47 Nobel laureates (faculty, alumni, or postdocs). Its history is the stuff of legend. In 1923, Robert Millikan won for measuring the charge of the electron. In 1954, Linus Pauling received the Chemistry Prize for explaining the nature of the chemical bond. He later won the Peace Prize for his anti-nuclear activism, making him the only person to win two unshared Nobels.

Stanford University sits not far behind, with 36 Nobel winners in its history and about 20 currently active in its community. From the development of transistors and lasers to modern work in medicine and economics, Stanford’s laureates have changed the modern world in ways that is impossible to quantify, but profound in their impact.

These numbers tell a clear story: since the mid-twentieth century, about one in every four Nobel Prizes in the sciences awarded to Americans has gone to researchers based at California institutions, an extraordinary concentration of curiosity, intellect, and ambition within a single state.

California’s Nobel dominance began early. In the 1930s, UC Berkeley’s Ernest Lawrence invented the cyclotron, a device that would transform physics and eventually medicine. Caltech, meanwhile, became a magnet for the world’s brightest physicists and chemists.

Over the decades, California’s universities turned their focus to molecular biology, biochemistry, and genetics. In the 1980s, the state’s physicists and engineers drove advances in lasers, semiconductors, and now, quantum circuits. And as biotechnology rose, San Diego and the Bay Area became ground zero for breakthroughs in medicine and life sciences. One of the great moments in genetics took place in Asilomar on the coast.

This is all about more than geography and climate (although those are a big sell, for sure). California’s research institutions kick ass because they operate as ecosystems rather than islands. Berkeley physicists collaborate with engineers at Stanford. Caltech chemists trade ideas with biotech firms in San Diego. Graduate students drift between labs, startups, and national research centers like Lawrence Livermore and JPL. The boundaries between university and industry blur, with campuses like Stanford turning breakthrough discoveries into thriving commercial ventures (look how many of our big tech brains came out of Stanford). In California, research doesn’t end in the lab, it often turns into companies, technologies, and treatments that generate both knowledge and enormous economic value. Just look at AI today.

I think the secret is cultural. Over the years, I’ve lived on the East coast for almost two decades, and abroad for several as well, and nothing compares to the California vibe. California has never been afraid of big risks. Its scientists are encouraged to chase questions that might take decades to answer (see our recent story on just this idea). There’s an openness to uncertainty here that works well in the natural sciences, but can also be found in Hollywood, Silicon Valley and, of course, space exploration.

When next year’s round of early morning calls comes from Stockholm, it is a good bet that someone in California will pick up. Maybe a physicist in Pasadena, a chemist in Berkeley, or a physician in La Jolla. Maybe they’ll pick up the phone in bed, maybe a text from a spouse while camping, or on a morning jog. That’s when a Swedish-accented voice tells them that the world has just caught up to what they’ve been quietly building for years.

The Unsung California Labs That Powered the Digital Revolution

When I started this Website, my hope was to share California’s astonishing range of landscapes, laboratories, and ideas. This state is overflowing with scientific discovery and natural marvels, and I want readers to understand, and enjoy, how unusually fertile this state is for discovery. If you’re not curious about the world, then this Website is definitely not for you. If you are, then I hope you get something out of it when you step outside and look around.

I spend a lot of time in the California mountains and at sea, and I am endlessly amazed by the natural world at our doorstep. I am also fascinated by California’s industrial past, the way mining, oil, and agriculture built its wealth, and how it later became a cradle for the technologies and industries now driving human society forward. Of course, some people see technologies like gene editing and AI as existential risks. I’m an optimist. I see tools that, while potentially dangerous, used wisely, expand what is possible.

Today’s story turns toward technology, and one breakthrough in particular that has reshaped the modern world. It is not just in the phone in your pocket, but in the computers that train artificial intelligence, in advanced manufacturing, and in the systems that keep the entire digital economy running. The technology is extreme ultraviolet lithography (EUV). And one of the most important points I want to leave you with is that the origins of EUV are not found in Silicon Valley startups or corporate boardrooms but in California’s national laboratories, where government-funded science made the impossible possible.

This article is not a political argument, though it comes at a time when government funding is often questioned or dismissed. My purpose is to underscore how much California’s national labs have accomplished and to affirm their value.

This story begins in the late 1980s and 1990s, when it became clear that if Moore’s Law was going to hold, chipmakers would need shorter and shorter wavelengths of light to keep shrinking transistors. Extreme ultraviolet light, or EUV, sits way beyond the visible spectrum, at a wavelength far shorter than ordinary ultraviolet lamps. That short wavelength makes it possible to draw patterns on silicon at the tiniest scales…and I mean REALLY tiny.

A Nobel Prize–winning physicist and co-founder of Lawrence Livermore National Laboratory, Lawrence’s legacy in nuclear science and high-energy research paved the way for the laboratory’s later breakthroughs in lasers and plasma physics — work that ultimately fed into the extreme ultraviolet light sources now powering the world’s most advanced chipmaking machines. (LLNL Public Domain)

At Lawrence Berkeley National Laboratory, researchers with expertise in lasers and plasmas were tasked with figuring out how to generate a powerful, reliable source of extreme ultraviolet light for chipmaking. Their solution was to fire high-energy laser pulses at microscopic droplets of tin, creating a superheated plasma that emits at just the right (tiny) wavelength for etching circuits onto silicon.

The movement of light on mirrors in an ASML EUV lithography machine. More on it below.

Generating the light was only the first step. To turn it into a working lithography system required other national labs to solve equally daunting problems. Scientists at Berkeley’s Center for X Ray Optics developed multilayer mirrors that could reflect the right slice of light with surprising efficiency. A branch of Sandia National Laboratories located in Livermore, California, worked on the pieces that translate light into patterns. So, in all: Livermore built and tested exposure systems, Berkeley measured and perfected optics and materials, and Sandia helped prove that the whole chain could run as a single machine.

Each EUV lithography machine is about the size of a bus, costs more than $150 million, and shipping one requires 40 freight containers, three cargo planes, and 20 trucks. (Photo: ASML)

It matters that this happened in public laboratories. The labs had the patient funding and the unusual mix of skills to attempt something that might not pay off for many years. The Department of Energy supported the facilities and the people. DARPA helped connect the labs with industry partners and kept the effort moving when it was still risky. There was no guarantee that the plasma would be bright enough, that the mirrors would reflect cleanly, or that the resists (the light-sensitive materials coated onto silicon wafers) would behave. The national labs could take that on because they are designed to tackle long horizon problems that industry would otherwise avoid.

Only later did private industry scale the laboratory breakthroughs into the giant tools that now anchor modern chip factories. The Dutch company ASML became the central player, building the scanners that move wafers with incredible precision under the fragile EUV light. Those systems are now capable of etching transistor features as small as 5 nanometers…5 billionths of a meter. You really can’t even use the “smaller than a human hair” comparison here since human hair variation is so large at this scale as to render that comparison kind of useless. However, many people still do.

The ASML machines are marvels of tech and engineering. Truly amazing feats human design. And they integrate subsystems from all over the world: Zeiss in Germany manufactures the mirrors, polished to near-atomic perfection, while San Diego’s Cymer (now part of ASML) supplies the laser-driven plasma light sources. The technology is so complex that a single scanner involves hundreds of thousands of components and takes months to assemble.

ASML’s EXE:5000 High-NA EUV lithography machine — a room-sized tool that etches the tiniest features on the world’s most advanced computer chips. (ASML)

It was TSMC and Samsung that then poured billions of dollars into making these tools reliable at scale, building the factories that now turn EUV light into the chips powering AI and smartphones and countless other devices. Trillions of dollars are at stake. Some say the fate of humanity lies in balance should Artificial General Intelligence eventually emerge (again, I don’t say that, but some do). All of this grew from the ingenuity and perseverance, along with the public funding, that sustained these California labs.

It’s disappointing that many of the companies profiting most from these technological breakthroughs are not based in the United States, even though the core science was proven here in California. That is fodder for a much longer essay, and perhaps even for a broader conversation about national industrial policy, something the CHIPS Act is only beginning to deal with.

However, if you look closely at the architecture of those monster machines, you can still see the fingerprints of the California work. A tin plasma for the light. Vacuum chambers that keep the beam alive. Reflective optics that never existed at this level before EUV research made them possible.

A photorealistic rendering of an advanced microprocessor, etched in silicon with extreme ultraviolet light — the kind of breakthrough technology pioneered in U.S. national labs, but now fabricated almost entirely in Taiwan, where the future of digital society is being made.

We often celebrate garages, founders, and the venture playbook. Those are real parts of the California story. This is a different part, just as important. The laboratories in Livermore, Berkeley, and Sandia are public assets. They exist because voters and policymakers chose to fund places where hard problems can be worked on for as long as it takes. The payoff can feel distant at first, then suddenly it is in your pocket. Like EUV. Years of quiet experiments on lasers, mirrors, and materials became the hidden machinery of the digital age.

The Physics and Geology of The Wedge, California’s Most Dangerous Wave

Dangerous surf at The Wedge in Newport Beach, California (Photo: Erik Olsen)

Would you support us? Just a few bucks. We’d appreciate it!

Having spent much of my youth in Newport Beach, my life was shaped by the ocean. I spent countless days in the surf, bodyboarding, bodysurfing, or playing volleyball on the sand with friends. When a southern storm rolled through, we’d rush to Big Corona and throw ourselves into the heavy swells, often getting slammed hard and learning deep respect for the ocean, a respect that I still harbor today. Sometimes the waves were so large they were genuinely terrifying, the kind of surf that would have made my mother gasp, had this not been an era when parents rarely knew what their kids were doing from dawn to dusk. That freedom, especially in Southern California, made the ocean feel like both a playground and a proving ground.

Across the channel at the Newport jetty was where the action was most intense. The surf was bigger, louder. We sat on the sand and held back, watching the brave and sometimes the foolish throw themselves into the water. That place, then and now, is called the Wedge.

There is something unforgettable about the Wedge and the way its waves crash with such raw force. Sometimes they detonate just offshore, sending water skyrocketing into the air; other times they slam thunderously against the sand, eliciting groans and whoops from bystanders. The waves behave strangely at the Wedge, smashing into one another, often combining their force, and creating moments of exquisite chaos.

These colliding waves are what make the place both spectacular and dangerous, the result of a unique mix of physics and geology that exists almost nowhere else on earth. That combination has made it, to this day, one of the world’s most famous surf and bodysurfing spots. If you want a glimpse of what I mean, just search YouTube, where the insanity speaks for itself. This compilation is from earlier this year.

And of course, who could forget this one surfer’s unique brand of SoCal eloquence.

So how did the Wedge turn into one of the most famous and dangerous surf spots? The truth is, it’s mostly the result of human engineering.

The Wedge’s origin story begins in the 1930s, when the U.S. Army Corps of Engineers extended Newport Harbor’s West Jetty to protect the harbor mouth from sand buildup and currents. What no one anticipated was that this angled wall of rock would create a perfect mirror for waves arriving from the south and southwest. Instead of dispersing, these waves slam into the jetty and reflect diagonally back toward the shore. The reflected energy doesn’t dissipate, it collides with the next incoming wave. When the two wave crests line up in phase, their energies combine, and the result is a much steeper, taller, and more powerful wave. In physics this is known as constructive interference: two sets of energy stacking into a single, towering peak.

This wave-doubling effect only works under specific conditions. Long-period south swells, often generated by hurricanes off Mexico or storms deep in the South Pacific, line up nearly parallel to the jetty. Their orientation means maximum contact and reflection. Surfers and bodysurfers describe the result as a pyramid-shaped breaker, or wedge, rising steeply before collapsing with extraordinary force. On the biggest days, these waves can reach 20 to 30 feet, twice the size of surrounding surf.

Geology and geography make the situation even more dramatic. The seafloor near The Wedge slopes upward very steeply into a narrow strip of beach. Instead of allowing waves to break gradually, the bathymetry forces them to jack up suddenly, creating a thick lip that pitches forward into shallow water. It’s called a shorebreak, and man, they can be dangerous. More on that in a moment.

Unlike classic point breaks such as Malibu, where waves peel cleanly along a gradual reef, The Wedge produces brutal closeouts: vertical walls of water that crash all at once, leaving no escape route.

It actually can get worse. After each wave explodes on the beach, the backwash races seaward, colliding with the next incoming swell and adding more turbulence. Surfers call it chaos; lifeguards call it dangerous, even life-threatening. Spinal injuries, broken bones, and concussions are common at The Wedge. By 2013, the Encyclopedia of Surfing estimated that the Wedge had claimed eight lives, left 35 people paralyzed, and sent thousands more to the hospital with broken bones, dislocations, and other trauma—making it the most injury-prone wave break in the world. A 2020 epidemiological survey places The Wedge among the most lethal surf breaks globally (alongside Pipeline and Teahupo’o), largely due to head-first “over the falls” impacts on the shallow sea floor.

Interesting fact: Long before the Wedge was built, the waves pounding that corner of the Newport Beach jetty were already fierce. In 1926, Hollywood icon John Wayne (then still Marion Morrison) tried bodysurfing there while he was a USC football player. He was slammed into the sand, shattering his shoulder and ending his athletic scholarship. The accident closed the door on his football career but opened the one that led him to Hollywood stardom.

Oceanographers have studied the physics behind the Wedge’s unique surfbreak in broader terms. Research into wave reflection and interference confirms what locals have known for decades: man-made structures like jetties can redirect swell energy in ways that amplify, rather than reduce, wave height. Studies on steep nearshore bathymetry show how sudden shoaling increases the violence of breaking waves. The Wedge combines both effects in one location, making it a rare and extreme case study in coastal dynamics. In other words, yes, it’s gnarly.

Of course, with all that danger comes spectacle, and when the Wedge is firing, it’s not unusual for hundreds of spectators to line the sand and jetty to watch. In August 2025, the California Coastal Commission approved plans for a 200-foot ADA-compliant concrete pathway and a 10-foot-wide viewing pad along the northern jetty, designed to make the experience safer and more inclusive. The project will provide better access for people using wheelchairs, walkers, and strollers, while also giving life guards and first responders improved vantage points when the surf turns chaotic.

I still get to the Wedge on occasion to watch the carnage. And while in my younger years, I might have ventured out to catch a wave or two if the conditions were relatively mellow, today, I prefer the view from shore, leaving the powerful surf to the younger bodysurfers hungry for a rush.

California’s Eye on the Cosmos: The SLAC-Built Camera That Will Time-Lapse the Universe

Images from the most powerful astronomical discovery machine ever created, and built in California

A breathtaking zoomed-in glimpse of the cosmos: this first image from the Vera C. Rubin Observatory reveals a deep field crowded with galaxies, offering just a taste of the observatory’s power to map the universe in unprecedented detail.

I woke up this morning to watch a much-anticipated press conference about the release of the first images from the Vera Rubin Telescope and Observatory. It left me flabbergasted: not just for what we saw today, but for what is still to come. The images weren’t just beautiful; they hinted at a decade of discovery that could reshape what we know about the cosmos.I just finished watching and have to catch my breath. What lies ahead is very, very exciting.

The first images released today mark the observatory’s “first light,” the ceremonial debut of a new telescope. These images are the result of decades of effort by a vast and diverse global team who together helped build one of the most advanced scientific instruments ever constructed. In the presser, Željko Ivezić, Director of the Rubin Observatory and the guy who revealed the first images, called it “the greatest astronomical discovery machine ever built.”

This image combines 678 separate images taken by NSF–DOE Vera C. Rubin Observatory in just over seven hours of observing time. Combining many images in this way clearly reveals otherwise faint or invisible details, such as the clouds of gas and dust that comprise the Trifid nebula (top) and the Lagoon nebula, which are several thousand light-years away from Earth.

The images shown today are a mere hors d’oeuvre of what’s to come, and you could tell by the enthusiasm and giddiness of the scientists involved how excited they are about what lies ahead. Here’s a clip of Željko Ivezić as the presser ended. It made me laugh.

So, that first image you can see above. Check out the detail. What would normally be perceived as black, empty space to us star-gazing earthlings shows anything but. It shows that in each tiny patch of sky, if you look deep enough, galaxies and stars are out there blazing. If you know the famous Hubble Deep Field image, later expanded by NASA’s James Webb Space Telescope, you may already be aware that there is no such thing as empty sky. The universe contains so much stuff, it is truly impossible for our brains (or at least my brain) to comprehend. Vera Rubin will improve our understanding of what’s out there and what we’ve seen before by orders of magnitude.

This image captures a small section of NSF–DOE Vera C. Rubin Observatory’s view of the Virgo Cluster, revealing both the grand scale and the faint details of this dynamic region of the cosmos. Bright stars from our own Milky Way shine in the foreground, while a sea of distant reddish galaxies speckle the background.

I’ve been following the Rubin Observatory for years, ever since I first spoke with engineers at the SLAC National Accelerator Laboratory about the digital camera they were building for a potential story for an episode of the PBS show NOVA that I produced (sadly, the production timeline ultimately didn’t work out). SLAC is one of California’s leading scientific institutions, known for groundbreaking work across fields from particle physics to astrophysics. (We wrote about it a while back.)

Now fully assembled atop Chile’s Cerro Pachón, the Vera C. Rubin Observatory is beginning its incredible and ambitious mission. Today’s presser focused on unveiling the first images captured by its groundbreaking camera, offering an early glimpse of the observatory’s vast potential. At the heart of the facility is SLAC’s creation: the world’s largest digital camera, a 3.2-gigapixel behemoth developed by the U.S. Department of Energy.

This extraordinary instrument is the central engine of the Legacy Survey of Space and Time (LSST), a decade-long sky survey designed to study dark energy, dark matter, and the changing night sky with unprecedented precision and frequency. We are essentially creating a decade-long time-lapse of the universe in detail that has never been captured before, revealing the dynamic cosmos in ways previously impossible. Over the course of ten years, it will catalog 37 billion individual astronomical objects, returning to observe each one every three nights to monitor changes, movements, and events across the sky. I want to learn more about how Artificial Intelligence and machine learning are being brought to bear to help scientists understand what they are seeing.

The camera, over 5 feet tall and weighing about three tons, took more than a decade to build. Its focal plane is 64 cm wide-roughly the size of a small coffee table-and consists of 189 custom-designed charge-coupled devices (CCDs) stitched together in a highly precise mosaic. These sensors operate at cryogenic temperatures to reduce noise and can detect the faintest cosmic light, comparable to spotting a candle from thousands of miles away.

Rubin’s camera captures a massive 3.5-degree field of view-more than most telescopes can map in a single shot. That’s about seven times the area of the full moon. Each image takes just 15 seconds to capture and only two seconds to download. A single Rubin image contains roughly as much data as all the words The New York Times has published since 1851. The observatory will generate about 20 terabytes of raw data every night, which will be transmitted via a high-speed 600 Gbps link to processing centers in California, France, and the UK. The data will then be routed through SLAC’s U.S. Data Facility for full analysis.

The complete focal plane of the future LSST Camera is more than 2 feet wide and contains 189 individual sensors that will produce 3,200-megapixel images. Crews at SLAC have now taken the first images with it. Explore them in full resolution using the links at the bottom of the press release.

The images produced will be staggering in both detail and scale. Each exposure will be sharp enough to reveal distant galaxies, supernovae, near-Earth asteroids, and other transient cosmic phenomena in real time. By revisiting the same patches of sky repeatedly, the Rubin Observatory will produce an evolving map of the dynamic universe-something no previous observatory has achieved at this scale.

What sets Rubin apart from even the giants like Hubble or James Webb is its speed, scope, and focus on change over time. Where Hubble peers deeply at narrow regions of space and Webb focuses on the early universe in infrared, Rubin will cast a wide and persistent net, watching the night sky for what moves, vanishes, appears, or explodes. It’s designed not just to look, but to watch. Just imaging the kind of stuff we will see!

The LSST Camera’s imaging sensors are grouped into units called “rafts.” Twenty-one square rafts, each with nine sensors, will capture science images, while four smaller rafts with three sensors each handle focus and telescope alignment. (Credit: Farrin Abbott/SLAC National Accelerator Laboratory)

This means discoveries won’t just be about what is out there, but what happens out there. Astronomers expect Rubin to vastly expand our knowledge of dark matter by observing how mass distorts space through gravitational lensing. It will also help map dark energy by charting the expansion of the universe with unprecedented precision. Meanwhile, its real-time scanning will act as a planetary defense system, spotting potentially hazardous asteroids headed toward Earth.

But the magic lies in the possibility of the unexpected. Rubin may detect rare cosmic collisions, unknown types of supernovae, or entirely new classes of astronomical phenomena. Over ten years, it’s expected to generate more than 60 petabytes of data-more than any other optical astronomy project to date. Scientists across the globe are already preparing for the data deluge, building machine learning tools to help sift through the torrent of discovery.

And none of it would be possible without SLAC’s camera. A triumph of optics, engineering, and digital sensor technology, the camera is arguably one of the most complex and capable scientific instruments ever built. I don’t care if you’re a Canon or a Sony person, this is way beyond all that. It’s a monument to what happens when curiosity meets collaboration, with California’s innovation engine powering the view.

As first light filters through the Rubin Observatory’s massive mirror and into SLAC’s camera, we are entering a new era of astronomy-one where the universe is not just observed, but filmed, in exquisite, evolving detail. This camera won’t just capture stars. It will reveal how the universe dances.

Berkeley’s Cosmic Breakthrough and the Alvarez Discovery That Rewrote Earth’s History

It is no coincidence that “Eureka” is the state motto of California. From its founding, the state has been a hub of groundbreaking discoveries, from the Gold Rush to advancements in space exploration, the rise of Silicon Valley and the development of modern computing, the development of seismic science, and the confirmation of the accelerating expansion of the universe. But one discovery made at the University of California, Berkeley, changed the way we see the world—or at least how it was almost destroyed, along with a huge part of life on the planet.

In 1977, Walter Alvarez arrived at Berkeley with rock samples from a small Italian town called Gubbio, unaware that they would help rewrite the history of life on Earth. He had spent years studying plate tectonics, but his father, Luis Alvarez, a Nobel Prize-winning physicist known for his unorthodox problem-solving at Berkeley, would propel him into a new kind of investigation, one deeply rooted in geology and Earth sciences. Their work led to one of the most significant scientific breakthroughs of the 20th century: the discovery that a massive meteorite impact was responsible for the extinction of the dinosaurs and much of life on Earth.

The samples Walter had collected contained a puzzling clay layer sandwiched between older and younger limestone deposits. This clay was rich in iridium—an element rare on Earth’s surface. The discovery of such an unusually high concentration of iridium in a single layer of buried rock was perplexing. Given that iridium is far more common in extraterrestrial bodies than on Earth’s surface, its presence suggested an extraordinary event—one that had no precedent in scientific understanding at the time. The implications were staggering: if this iridium had arrived all at once, it pointed to a cataclysmic event unlike anything previously considered in Earth’s history. Although some scientists had speculated about meteor impacts, solid evidence was scarce.

Alvarez determined that this layer corresponded precisely to the Cretaceous-Paleogene (K-Pg) boundary (formerly called Cretaceous–Tertiary or K–T boundary), the geological marker of the mass extinction that eradicated the non-avian dinosaurs 66 million years ago. Scientists had long debated the cause of this catastrophe, proposing theories ranging from volcanic activity to gradual climate change. But the Alvarez team would introduce a radical new idea—one that required looking beyond Earth.

Mass extinctions stand out so distinctly in the fossil record that the very structure of geological time is based on them. In 1841, geologist John Phillips divided life’s history into three chapters: the Paleozoic, or “ancient life”; the Mesozoic, or “middle life”; and the Cenozoic, or “new life.” These divisions were based on abrupt breaks in the fossil record, the most striking of which were the end-Permian extinction and the end-Cretaceous extinction, noted here. The fossils from these three eras were so different that Phillips originally believed they reflected separate acts of creation. Charles Lyell, one of the founders of modern geology, observed a “chasm” in the fossil record at the end of the Cretaceous period, where species such as belemnites, ammonites, and rudist bivalves vanished entirely. However, Lyell and later Charles Darwin dismissed these apparent sudden extinctions as mere gaps in the fossil record, preferring the idea of slow, gradual change (known as gradualism, versus catastrophism). Darwin famously compared the fossil record to a book where only scattered pages and fragments of lines had been preserved, making abrupt transitions appear more dramatic than they were.

Luis Alvarez was a physicist whose career had spanned a remarkable range of disciplines, from particle physics to aviation radar to Cold War forensics. He had a history of bold ideas, from using muon detectors to search for hidden chambers in pyramids to testing ballistic theories in the Kennedy assassination with watermelons. When Walter shared his perplexing stratigraphic findings, Luis proposed a novel method to measure how long the clay layer had taken to form: by analyzing its iridium content.

As discusses, Iridium is a rare element on Earth’s surface but is far more abundant in meteorites. Luis hypothesized that if the clay had accumulated slowly over thousands or millions of years, it would contain only tiny traces of iridium from cosmic dust. But if it had been deposited rapidly—perhaps by a single catastrophic event—it might show an anomalously high concentration of the element. He reached out to a Berkeley colleague, Frank Asaro, whose lab had the sophisticated equipment necessary for this kind of analysis.

Nine months after submitting their samples, Walter received a call. Asaro had found something extraordinary: the iridium levels in the clay layer were off the charts—orders of magnitude higher than expected. No one knew what to make of this. Was it a weird anomaly, or something more significant? Walter flew to Denmark to collect some late-Cretaceous sediments from a set of limestone cliffs known as Stevns Klint. At Stevns Klint, the end of the Cretaceous period shows up as a layer of clay that’s jet black and contains high amounts of organic material, including remnants of ancient marine life. When the stinky Danish samples were analyzed, they, too, revealed astronomical levels of iridium. A third set of samples, from the South Island of New Zealand, also showed an iridium “spike” right at the end of the Cretaceous. Luis, according to a colleague, reacted to the news “like a shark smelling blood”; he sensed the opportunity for a great discovery.

The Alvarezes batted around theories. But all the ones they could think of either didn’t fit the available data or were ruled out by further tests. Then, finally, after almost a year’s worth of dead ends, they arrived at the impact hypothesis. On an otherwise ordinary day sixty-six million years ago, an asteroid six miles wide collided with the Earth. Exploding on contact, it released energy on the order of a hundred million megatons of TNT, or more than a million of the most powerful H-bombs ever tested. Debris, including iridium from the pulverized asteroid, spread around the globe. Day turned to night, and temperatures plunged. A mass extinction ensued. Even groups that survived, like mammals and lizards, suffered dramatic die-offs in the aftermath. Who perished, and who survived, set the stage for the next 66 million years—including our own origin 300,000 years ago.

The Alvarezes wrote up the results from Gubbio and Stevns Klint and sent them, along with their proposed explanation, to Science. “I can remember working very hard to make that paper just as solid as it could possibly be,” Walter later recalled. Their paper, Extraterrestrial Cause for the Cretaceous-Tertiary Extinction, was published in June 1980. It generated enormous excitement, much of it beyond the bounds of paleontology, but it was also ridiculed by some who considered the idea far-fetched, if not ridiculous. Journals in disciplines ranging from clinical psychology to herpetology reported on the Alvarezes’ findings, and soon the idea of an end-Cretaceous asteroid was picked up by magazines like Time and Newsweek. In an essay in The New York Review of Books, the late American paleontologist Stephen Jay Gould quipped that linking dinosaurs—long an object of fascination—to a major cosmic event was “like a scheme a clever publisher might devise to ensure high readership.”

Inspired by the impact hypothesis, a group of astrophysicists led by Carl Sagan decided to try to model the effects of an all-out war and came up with the concept of “nuclear winter,” which, in turn, generated its own wave of media coverage. But as the discovery sank in among many professional paleontologists, the Alvarezes’ idea—and in many cases, the Alvarezes themselves—were met with hostility. “The apparent mass extinction is an artifact of statistics and poor understanding of the taxonomy,” one paleontologist told The New York Times. “The arrogance.”

Skepticism was immediate and intense. Paleontologists, geologists, and physicists debated the implications of the iridium anomaly. But as the search for supporting evidence intensified, the pieces of the puzzle began to fall into place. Shocked quartz, a telltale sign of high-energy impacts, was found at sites around the world. Soot deposits suggested massive wildfires had raged in the aftermath.

In the early 1990s, conclusive evidence finally emerged. The Chicxulub crater, measuring roughly 180 kilometers across and buried under about half a mile of sediment in Mexico’s Yucatán Peninsula, was identified as the likely impact site. Although it was first detected by Mexico’s state-run oil company (PEMEX) in the 1950s during geophysical surveys, core samples taken decades later clinched the identification of Chicxulub as the long-sought impact site linked to the mass extinction that ended the Cretaceous era.

One of the more intriguing (if not astounding) recent discoveries tied to the end-Cretaceous impact is a site called Tanis, located in North Dakota’s Hell Creek Formation. Discovered in 2019 by a team led by Robert DePalma and spotlighted in a New Yorker article, Tanis preserves a remarkable snapshot of what appears to be the immediate aftermath of the asteroid strike.

The sedimentary layers at Tanis indicate large waves—often called “seiche waves”—that may have surged inland in the immediate aftermath of the impact. They also contain countless tiny glass spherules that rained down after the explosion. Known as microtektites, these blobs form when molten rock is hurled into the atmosphere by an asteroid collision and solidifies as it falls back to Earth. The site appears to hold them by the millions. In some cases, fish fossils have been found with these glass droplets lodged in their gills—a striking testament to how suddenly life was disrupted.

Although still under investigation, Tanis has drawn attention for its exceptional level of detail, potentially capturing events that took place within mere hours of the impact. The precise interpretation of this site continues to spark controversy among researchers. There is also controversy about the broader cause of the mass extinction itself: the main competing hypothesis is that the colossal “Deccan” volcanic eruptions, in what would become India, spewed enough sulfur and carbon dioxide into the atmosphere to cause a dramatic climatic shift. However, the wave-like deposits, along with the abundant glass spherules, suggest a rapid and violent disturbance consistent with a massive asteroid strike. Researchers hope to learn more about the precise sequence of disasters that followed—tidal waves, intense firestorms, and global darkness—further fleshing out the story of how the world changed so drastically, so quickly.

All said, today the Alvarez hypothesis is widely accepted as the leading explanation for the K-Pg mass extinction. Their contributions at UC Berkeley—widely recognized as one of the world’s preeminent public institutions—not only reshaped our understanding of Earth’s history but also changed how we perceive planetary hazards. The realization that cosmic collisions have shaped life’s trajectory has led to renewed interest in asteroid detection and planetary defense.

Walter and Luis Alvarez’s discovery was a testament to the power of interdisciplinary science and the willingness to follow unconventional ideas. Their pursuit of an extraterrestrial explanation for a terrestrial mystery reshaped paleontology, geology, and astrophysics. What began with a father and son pondering an ancient Italian rock layer ended in a revelation that forever changed how we understand the history of life—and its vulnerability to forces from beyond our world.

Standing at Moss Landing, a quaint coastal town known for its fishing heritage, bustling harbor, and the iconic twin smokestacks of its power plant, you might never guess that a massive geological feature lies hidden beneath the waves. From this unassuming spot on the California coast, Monterey Canyon stretches into the depths, a colossal submarine landscape that rivals the grandeur of the Grand Canyon itself.

Monterey Canyon, often called the Grand Canyon of the Pacific, is one of the largest and most fascinating submarine canyons in the world. Stretching over 95 miles from the coast of Monterey, California, and plunging to depths exceeding 3,600 meters (11,800 feet), this underwater marvel rivals its terrestrial counterpart in size and grandeur. Beneath the surface of Monterey Bay, the canyon is a hotspot of geological, biological, and scientific exploration, offering a window into Earth’s dynamic processes and the mysterious ecosystems of the deep sea.

Monterey Canyon owes its impressive scale and structure to the patient yet powerful forces of geological time. Formed over millions of years, Monterey Canyon has been shaped by a range of geological processes. One prevailing theory is that the canyon began as a river channel carved by the ancestral Salinas River, which carried sediments from the ancient Sierra Nevada to the ocean. As sea levels fluctuated during ice ages, the river extended further offshore, deepening the canyon through erosion. Another hypothesis points to tectonic activity along the Pacific Plate as a significant factor, creating fault lines and uplifting areas around the canyon while subsidence allowed sediment to accumulate and flow into the deep. These forces, combined with powerful turbidity currents—underwater landslides of sediment-laden water—worked in tandem to sculpt the dramatic contours we see today. Together, one or several of these processes forged one of Earth’s most dramatic underwater landscapes.

While the geology is awe-inspiring, the biology of Monterey Canyon makes it a living laboratory for scientists. The canyon is teeming with life, from surface waters to its darkest depths. Near the top, kelp forests and sandy seafloors support a wide variety of fish, crabs, and sea otters, while the midwater region, known as the “twilight zone,” is home to bioluminescent organisms like lanternfish and vampire squid that generate light for survival. Lanternfish, for example, employ bioluminescence to attract prey and confuse predators, while vampire squid use light-producing organs to startle threats or escape unnoticed into the depths. In the canyon’s deepest reaches, strange and hardy creatures thrive in extreme conditions, including the ghostly-looking Pacific hagfish, the bizarre gulper eel, and communities of tube worms sustained by chemical energy from cold seeps.

The barreleye fish, captured in stunning video footage by MBARI, is one of the canyon’s most fascinating inhabitants. This deep-sea fish is known for its’ domed transparent head, which allows it to rotate its upward-facing eyes to track prey and avoid predators in the dimly lit depths. Its unique adaptations highlight the remarkable ingenuity of life in the deep ocean. Countless deep-sea creatures possess astonishing adaptations and behaviors that continue to amaze scientists and inspire awe. Only in recent decades have we gained the technology to explore the depths and begin to uncover their mysteries.

The canyon’s rich biodiversity thrives on upwelling currents that draw cold, nutrient-rich water to the surface, triggering plankton blooms that sustain a complex food web. This process is vital in California waters, where it supports an astonishing array of marine life, from deep-sea creatures to surface dwellers like humpback whales, sea lions, and albatrosses. As a result, Monterey Bay remains a crucial habitat teeming with life at all levels of the ocean.

What sets Monterey Canyon apart is the sheer accessibility of this underwater frontier for scientific exploration. The canyon’s proximity to the shore makes it a prime research site for organizations like the Monterey Bay Aquarium Research Institute (MBARI). Using remotely operated vehicles (ROVs) and advanced oceanographic tools, MBARI scientists have conducted groundbreaking studies on the canyon’s geology, hydrology, and biology. Their research has shed light on phenomena like deep-sea carbon cycling, the behavior of deepwater species, and the ecological impacts of climate change.

This animation, the most detailed ever created of Monterey Canyon, combines ship-based multibeam data at a resolution of 25 meters (82 feet) with high-precision autonomous underwater vehicle (AUV) mapping data at just one meter (three feet), revealing the canyon’s intricate underwater topography like never before.

MBARI’s founder, the late David Packard, envisioned the institute as a hub for pushing the boundaries of marine science and engineering, and it has lived up to this mission. Researchers like Bruce Robison have pioneered the use of ROVs to study elusive deep-sea animals, capturing stunning footage of creatures like the vampire squid and the elusive giant siphonophore, a colonial organism that can stretch over 100 feet, making it one of the longest animals on Earth.

Among the younger generations of pioneering researchers at MBARI, Kakani Katija stands out for her groundbreaking contributions to marine science. Katija has spearheaded the development of FathomNet, an open-source image database that leverages artificial intelligence to identify and count marine animals in deep-sea video footage, revolutionizing how researchers analyze vast datasets. Her work has also explored the role of marine organism movements in ocean mixing, revealing their importance for nutrient distribution and global ocean circulation. These advancements not only deepen our understanding of the deep sea but also showcase how cutting-edge technology can transform our approach to studying life in the deep ocean.

Two leading scientists at MBARI, Steve Haddock and Kyra Schlining, have made groundbreaking discoveries in Monterey Canyon, expanding our understanding of deep-sea ecosystems. Haddock, a marine biologist specializing in bioluminescence, has revealed how deep-sea organisms like jellyfish and siphonophores use light for communication, camouflage, and predation. His research has uncovered new species and illuminated the role of bioluminescence in the deep ocean. Schlining, an expert in deep-sea video analysis, has played a key role in identifying and cataloging previously unknown marine life captured by MBARI’s remotely operated vehicles (ROVs). Her work has helped map the canyon’s biodiversity and track environmental changes over time, shedding light on the delicate balance of life in this hidden world.

Monterey Canyon continues to inspire curiosity and collaboration. Its unique conditions make it a natural laboratory for testing cutting-edge technologies, from autonomous underwater vehicles to sensors for tracking ocean chemistry. The canyon also plays a vital role in education and conservation efforts, with institutions like the Monterey Bay Aquarium engaging visitors and raising awareness about the importance of protecting our oceans.

As we venture deeper into Monterey Canyon—an astonishing world hidden just off our coast—we find ourselves with more questions than answers. How far can life push its limits? How do geology and biology shape each other in the depths? And how are human activities altering this fragile underwater landscape? Yet with every dive and every discovery, we get a little closer to unraveling the mysteries of one of Earth’s last great frontiers: the ocean.

JPL and the Voyager Golden Record: Humanity’s A Cosmic Mixtape in Space

Support California Curated with a small donation.

The Jet Propulsion Laboratory (JPL) in La Canada Flintridge, California is well-known for building and sending spacecraft far into the cosmos to help us better understand the universe. But the agency was also extensively involved in one of the most ambitious and symbolic projects in the history of space exploration, one that in many ways was more art than science: the Voyager Golden Record.

In 1977, as the twin Voyager spacecraft prepared to journey beyond the confines of our solar system, they carried with them what might be the most profound artifacts ever created by humanity: the Voyager Golden Records. These records, designed to last a billion years, are time capsules intended not for Earthlings but for potential extraterrestrial finders or future humans. Engraved in gold-plated copper discs, the records encapsulate the Earth’s diverse cultural and natural heritage—from music to languages to sounds of nature.

The idea of the Golden Record was developed by a talented team led by Carl Sagan, the renowned astronomer and science communicator. Sagan, alongside other prominent figures such as Frank Drake, Ann Druyan, science journalist Jon Lomberg, and Linda Salzman Sagan, crafted a selection that aimed to represent the entirety of Earth. The content ranged from classical music by Bach and Beethoven to greetings in 55 languages, natural sounds like thunderstorms and whales, and a diverse set of 115 images depicting life and culture on Earth.

But producing a record that could survive the harsh environment of space, while also being understandable and playable by beings of unknown technology, posed unique challenges. This is where the Jet Propulsion Laboratory (JPL) stepped in, playing a pivotal role in transforming this ambitious vision into a tangible, durable artifact capable of traversing the cosmos.

JPL, managed by Caltech under a NASA contract, was primarily responsible for the construction and operation of the Voyager spacecraft. Their expertise was crucial not just in the scientific instrumentation and engineering of the spacecraft but also in integrating the Golden Records. The lab’s engineers worked meticulously to ensure that the records were equipped with everything needed for potential playback: a cartridge, a needle, and symbolic instructions detailing their use. These instructions, etched onto the record’s cover, provided a universal map indicating Earth’s location in relation to pulsar stars, which are highly stable and can be used as galactic landmarks.

JPL’s involvement extended to the actual physical preparation of the records. They coordinated closely with RCA Records to produce the master disc from which the Voyager records were replicated. The final products were then plated in gold and encased in a protective aluminum jacket, designed to withstand the vacuum of space, cosmic rays, and extreme temperatures.

The technical contributions of JPL ensured that the Golden Records were not only a feat of cultural expression but also a marvel of scientific and engineering ingenuity. By equipping the Voyager spacecraft with these messages, JPL helped bridge the human desire to explore and communicate with the tangible reality of space travel. The records, mounted aboard Voyagers 1 and 2, continue to be ambassadors of Earth, carrying sounds, music, and images intended to convey the story of our world to whoever, or whatever, might find them.

Today, both Voyager spacecraft, with their Golden Records, have entered interstellar space, marking them as the most distant human-made objects in existence. They serve as reminders of humanity’s ambition to reach beyond our immediate grasp and to communicate across vast cosmic distances. JPL’s role in this historic endeavor highlights the profound connection between human creativity and technological advancement, ensuring that our message to the cosmos will endure long after the original voices have faded.

As these records voyage through the cosmos, they remind us not just of where we have been, but also of the far reaches that our curiosity can take us. Through the combined efforts of visionaries like Carl Sagan and the engineering prowess of JPL, the Voyager Golden Record stands as a testament to the best of human knowledge, culture, and technological achievement.

The Voyager Golden Records are phonograph records, much like the vinyl records used to listen to music before digital media became widespread. They are constructed from copper discs coated in gold to withstand the harsh environment of space. Each record is encased in a protective aluminum jacket, along with a cartridge and a needle. Instructions in symbolic language explain the origin of the spacecraft and indicate how the record should be played. The playback speed (16 2/3 revolutions per minute) is much slower than typical records, which typically spin at 33 1/3 or 45 rpm.

The content of the Golden Record is a meticulously curated selection intended to represent the diversity of life and culture on Earth:

Sounds of Earth: The records include audio of nature sounds like thunder, wind, and animals (including the songs of birds and whales). Human sounds like footsteps, a heartbeat, and laughter are also embedded, capturing the biological and social essence of Earth.

Musical Selections: There are 27 musical tracks from different cultures and eras, ranging from classical pieces by Bach and Beethoven to traditional songs from various cultures, including a Navajo chant and a Peruvian wedding song. These selections were intended to showcase the diversity of musical expression on Earth.

Greetings in 55 Languages: A variety of spoken greetings from “Hello” in English to ancient languages like Akkadian. The inclusion of a broad range of languages aims to depict the linguistic diversity of humanity.

Images: The record also contains 115 analog-encoded photographs and diagrams. These images show a wide range of subjects, including humans of different sexes and races, everyday activities, scientific knowledge like mathematical definitions, and the Solar System. The intent was to offer a visual summary of our planet and its inhabitants.

Message from the UN Secretary-General and the President of the United States: There are also printed messages from prominent global leaders at the time, including U.S. President Jimmy Carter and United Nations Secretary-General Kurt Waldheim.

Sounds of Human Origin: Beyond natural and environmental sounds, the record also includes a montage of the sounds of Earth, a screaming chimpanzee, a medley of human-originated noises like tools, vehicles, and a kiss, among others.

The idea behind the Voyager Golden Record is not just to communicate where and who we are but also to share a message of hope and peace with any possible recipient, even if that recipient is far in the future. The chances of the Voyager spacecraft actually being found by extraterrestrial life are slim, but the Golden Record serves as a profound gesture of goodwill and a testament to the human spirit’s longing to reach out and explore the universe.
