Sometimes, the scientific knowledge of the time has provided a clear and reasoned explanation for these phenomena, but in many other cases, it has not.

When we cannot explain certain events with the knowledge available to us, we are left perplexed and astonished. It is in these moments that we turn to supernatural explanations, resorting to magic or religion.

When we lean on religious beliefs, we assume that these strange and seemingly inexplicable phenomena are the result of the intervention of beings with capabilities far beyond our own—beings we generally call “gods.”

And at that moment, the phenomenon transforms into a “miracle.”

However, the advancement of science over the centuries has allowed us to verify that many of these miracles—many of the phenomena once considered supernatural or unfathomable—actually have scientific, natural explanations.

And in many cases, the ultimate culprits behind these phenomena have been microbes.

One of the most representative “miraculous” microbes is the bacterium known as Serratia marcescens.

Serratia is a microbe capable of staining surfaces where its colonies grow with a blood-red color—such as bread or even religious statues.

It is precisely its proliferation on these two elements that led to the belief that the liquid emanating from them was real blood.

It is not surprising that, due to these characteristics, scientists have nicknamed this microorganism the “miraculous bacterium” and have named the blood-red pigment it produces “prodigiosin.”

Serratia, whose typically bacterial circular chromosome contains only about 4,800 genes, is a rod-shaped bacterium—what microbiologists call a bacillus. Like most bacteria, it is tiny, measuring no more than two-thousandths of a millimeter in length.

We can find it almost everywhere: in the soil, in water, on plants, on animals… It is, in essence, a cosmopolitan bacterium.

As is often the case with most bacteria, we only become aware of its existence when its uncontrolled growth causes health problems for us or the ecosystems in which we live.

When its growth within our bodies becomes unregulated, Serratia can cause conjunctivitis, infections in wounds, kidneys, and urinary tracts, respiratory infections, meningitis, and endocarditis. In fact, some historians claim that this bacterium has caused more deaths than any other bacillus in human history.

Today, Serratia is frequently associated with various serious hospital-acquired infections, particularly dangerous for immunocompromised patients. For this reason, it is intensively studied in laboratories and hospitals.

But not everything about it is negative.

As a result of these studies, researchers have discovered that Serratia’s pigment, prodigiosin, induces apoptosis in cancer cells—that is, it triggers their natural death. It also acts as an immunosuppressive drug in organ transplant surgeries, preventing rejection.

Moreover, it has been found that this pigment is highly effective against one of the life stages of the spirochete Borrelia burgdorferi, the bacterium that causes Lyme disease and is transmitted by ticks.

Nature itself, the evolution of life on our planet, offers us countless examples of phenomena that could be considered “miracles.”

And once again, bacteria play a starring role.

One such example is the drastic transformation of our atmosphere approximately 2.4 billion years ago.

Until then, Earth’s atmosphere was dominated by gases such as hydrogen, water vapor, carbon monoxide, carbon dioxide, methane, hydrogen sulfide, and various nitrogen compounds—remnants of the planet’s formation and the numerous celestial impacts on its surface.

This primitive atmosphere contained almost no free oxygen—it was an anaerobic atmosphere.

During this extended period of our planet’s evolution, life was entirely prokaryotic, meaning all living beings were bacteria and archaea.

For millions of years, some of these microorganisms were able to harness energy from sunlight to perform photosynthesis.

However, the type of photosynthesis they carried out—and still do, as many of these organisms continue to share the planet with us—did not release oxygen. This is what we call anoxygenic photosynthesis.

These microorganisms did not break down water to obtain energy but instead used a compound similar in structure to water: hydrogen sulfide, the substance responsible for the foul smell of “rotten eggs.” In those early days of Earth, volcanic activity was the main source of this compound.

As a result, instead of releasing oxygen, these microorganisms released sulfur.

When hydrogen sulfide was broken down, two elements appeared: hydrogen, which the bacteria used for their metabolism, and sulfur, which was often deposited as elemental sulfur granules either in the environment or within bacterial cells.

Then, about 3 billion years ago, a special type of bacteria—the cyanobacteria—figured out how to use a much more abundant compound thanhydrogen sulfide: water.

This new metabolic innovation, known as oxygenic photosynthesis, was fundamental to the evolution of life on Earth. Instead of releasing sulfur, it led to the release of oxygen—a highly reactive and initially toxic gas.

The oxygen released accumulated in the oceans, where it reacted with dissolved chemical elements, removing it from the environment.

One of these elements was iron, which was extraordinarily abundant due to the planet’s formation processes.

Oxygen reacted with iron to form iron oxide, which settled into ocean sediments. As a result, very little of the oxygen produced by bacterial photosynthesis escaped into the atmosphere.

A clear record of this process is found in extraordinary geological formations known as banded iron formations, which can be observed in many regions of the planet.

Then, about 2.4 billion years ago, the amount of dissolved iron in ocean water was no longer sufficient to capture all the oxygen produced by bacterial photosynthesis. Oxygen began to accumulate in the atmosphere in large quantities, rising from about 1% to the 21% we have today.

This event is known as the Great Oxidation Event.

The organisms that had lived on Earth until then were not adapted to an oxygen-rich atmosphere, which was highly toxic to them. This led to a massive extinction.

Almost all life on the planet disappeared, and new forms of life began to evolve—ones capable of developing strategies to protect themselves from the dangerous gas.

The majority of life on Earth transitioned from anaerobic to aerobic, as it is today.

And there’s more.

Around 2 billion years ago, some of these new, more complex life forms—capable of surviving in an oxygenated environment because they had incorporated oxygen-respiring bacteria that would later become mitochondria—engulfed a small cyanobacterium. Instead of digesting it, they allowed it to live inside them.

Over time, this cyanobacterium became a chloroplast, the organelle most characteristic of all plant cells.

As a result, the new cell, which could already survive in an oxygenated environment, also became capable of harnessing solar energy for its metabolism—meaning it could now perform photosynthesis.

What was the outcome of this extraordinary union, this marvelous bacterial symbiosis?

The result was the birth of the first plant cell—the type of cell that forms all the plants we see today, from tiny unicellular algae like diatoms to giant trees that breathe life into our forests.

Today, various studies show that free-living cyanobacteria are responsible for between 50% and 70% of the oxygen released into the atmosphere from the planet’s surface. However, since they became chloroplasts and now form part of all plant cells, cyanobacteria are actually responsible for nearly 100% of the oxygen in our atmosphere.

Could there be more “miraculous” microbes than these?

Surely, just by seeing the platform’s name, you’ve already guessed that Fundación La Caixa is behind this wonderful initiative—a bold and innovative project that aims to make cultural content accessible to anyone who wants it. And the best part? It’s completely free! (I’ll tell you more about that later).

The presentation was spectacular, featuring a wonderful musical performance by Oscar D’aniello (Delafé).

Cayetana Guillén Cuervo, current president of the Academy of Performing Arts, actress, and television presenter, among many other things, served as the master of ceremonies with her characteristic grace and elegance. One by one, the different “protagonists”—people who have participated in some of the platform’s available content—took the stage at her invitation.

Seated on the stage’s “chester” (sofa) were Elisa Durán (Deputy General Director of Fundación La Caixa), Víctor García de Gomar (Artistic Director of Gran Teatre del Liceu), Guillermo Solana (Artistic Director of the Thyssen-Bornemisza National Museum), Leticia Dolera (actress, director, and audiovisual producer) and María Arnal (artist and composer), who also delighted us all with a beautiful rendition of El Cant de la Sibil·la.

As you can see, all these figures fit within the traditional concept of “culture”—painting, theater, cinema, music…

But to fulfill the platform’s broader vision, as expressed at the beginning by Elisa Durán, something was missing: science.

That’s why, at Cayetana’s invitation, two much lesser-known figures took the stage: Bartolomé Luque (Doctor in Physical Sciences and professor at the Polytechnic University of Madrid) and myself (labeled as a biologist, science communicator, and photographer).

There we were, Bartolo (only my mother calls him Bartolomé, sic) and I, sitting on the famous “chester,” probably sparking the curiosity of the audience, who likely knew little about us. And that’s precisely what we talked about—the curiosity that drives knowledge and the false distinction between science and culture, a misconception that CaixaForum+ is fortunately working to dismantle. We also discussed the importance of scientific rigor in communication, the pandemic, Einstein, the first step on the Moon, the Fourier transform, algebra, numbers and letters, the invisible, the idea of being “a science person” or “a humanities person,” religion and science, flat-earthers and anti-vaxxers… basically, if they had let us, we would have talked about The Thirty Pieces of Silver too! Some of Bartolo’s examples even got the audience laughing (Science and humor? Apparently, it’s possible—even while taking science completely seriously!). In the end, thanks to Bartolo’s spontaneity and my txapela (Basque beret), we earned the (hopefully affectionate) nickname “the odd couple.”

A key role in shaping this “odd couple” was played by Mireia Gubern, Marta Morales, and Ignasi Miró from Fundación La Caixa’s Corporate Directorate of Culture and Science, with whom I have a wonderful working relationship.

I encourage everyone to subscribe to the platform, either via the web version (https://caixaforumplus.org/) or through the tablet and mobile app, available on Google Play and the App Store.

There, among more than 900 productions and 600 hours of content (a number that will continue to grow), you’ll find our series Habitantes del Micromundo (Inhabitants of the Microworld), where you can learn more about the “invisible” beings I mentioned earlier.

And speaking of the invisible, I’d like to express my heartfelt gratitude to the amazing team working behind the scenes at the event—sound technicians, makeup artists, stage coordinators—for their kindness and support at all times. Thank you all so much!

Yes, for three months, from November 29, 2022, to February 26, 2023, the bacteria we have been cultivating and caring for in our studio for over five months will be “speaking” in Euskara. They have traveled to Bilbao to settle in Azkuna Zentroa as part of the exhibition “Zientzia Frikzioa. Bizitza espezie lagunen artean” (Science Friction: Life Among Companion Species).

SCIENCE FRICTION: LIFE AMONG COMPANION SPECIES

There, they are sure to feel right at home, surrounded by works from artists such as Petra Maitz, Susana Talayuelo, Ernesto Casero, Shoshanah Dubiner, and Diana Toucedo, among others, as well as scientific institutions like Aranzadi Zientzia Elkartea and the Elgoibar Museum of Fossils and Minerals (Mufomi).

The exhibition, a co-production of Azkuna Zentroa and the Centre de Cultura Contemporània de Barcelona (CCCB), was previously showcased in 2021 at the CCCB under the title “Ciència Fricció. Vida entre espècies companyes.” Now, with some adaptations to fit the new exhibition space, it has arrived at Bilbao’s former Alhóndiga.

And there they are—our three Winogradsky columns and a small piece of microbial mat from the Ebro Delta—serving as introductory elements to the work and theories of the American biologist Lynn Margulis (1938–2011). She can also be seen and heard through excerpts from John Feldman’s film “Symbiotic Earth: How Lynn Margulis Rocked the Boat and Started a Scientific Revolution,” in which we had the pleasure of collaborating. These excerpts are displayed on a screen next to “our bacteria.”

Ana and Iker (Science into Images)

After the CCCB exhibition opening in 2021, I wrote a blog post about it (you can read it HERE), but I felt like writing about it again—not just because it is now in Bilbao but especially to highlight the dedication and effort of the team that welcomed us with open arms and took special care of both our bacteria and the Science into Images team members who traveled to Bilbao (Ana, Iker, and myself).

Maintaining living organisms in an exhibition of this nature is no easy task—especially because the transfer from our studio to Azkuna Zentroa is difficult and stressful, particularly for the microbial mat. However, both María Ptqk (the exhibition curator) and the Azkuna Zentroa team—especially Marina Urrutikoetxea (Cultural Programming and Education Technician), Rakel Esparza (Head of Cultural Programming), Iraia Olea (Cultural Programming Administrative), and Olaia Ibarzabal (Cultural Production Technician)—have given us their full support and care (as well as to our tiny creatures).

In my previous blog post after the CCCB inauguration, I highlighted the figure of Josep Querol, whom we affectionately nicknamed “the microbiologist resurrector.” This time, I want to recognize Olaia Ibarzabal, who could also be given that same honorary title. She has been, is, and will be the “nanny” of our bacteria for as long as they remain at Azkuna. And who knows—she might even teach them to speak Euskara!

Lynn Margulis, in one of her lectures, while discussing the fact that bacteria evolved just fine without us and will continue evolving just as well once we are gone, showed images of bacteria “dancing and singing” to Viola Wills’ song “Gonna Get Along Without You Now.” She even translated what the bacteria were saying so the audience could understand them. Perhaps, at some point, Olaia will also translate for the exhibition visitors what our bacteria are telling us: “Zu gabe jarraituko dugu” (We will continue without you).

If you want to watch the exhibition presentation from November 29, HERE is the link to the video published by Azkuna Zentroa.

“Every once in a while, life has coffee with me
And looks so beautiful it’s a joy to see.
She lets her hair down and invites me
To step onto the stage with her.”

The truth is that this time, life not only had coffee with me but also a good amount of garagardoa and sagardoa—words that, for those of us who don’t speak Euskara, mean beer and cider, respectively.

But let’s get to the important part.

Last Thursday, October 28, I had the pleasure and honor of presenting a screening of John Feldman’s documentary film “Symbiotic Earth: How Lynn Margulis Rocked the Boat and Started a Scientific Revolution” at the Aita Mari cinema in Zumaia.

This event was part of the “Parallel Activities” organized as a complement to the series “Cooperation, an Evolutionary Force. Lynn Margulis, 10 Years Later,” an effort to decentralize the main events, most of which are being held in Barcelona.

For two and a half extraordinary hours (the length of the film), more than 60 people had the opportunity to learn about Lynn Margulis—some for the first time—as well as her groundbreaking scientific theories on the evolution of life on our planet (you know, endosymbiosis, serial endosymbiosis, and symbiogenesis).

It doesn’t surprise me that for biologists like myself, or for those studying other natural sciences, Lynn’s proposals are inherently fascinating (I won’t get into the implications they have for our understanding of biological evolution here). And her figure is, of course, incredibly compelling. However, what does surprise me (though only to a certain extent) is the interest she sparks among people more associated with the humanities—especially in sociology.

I am convinced that this interest arises from the proposal of a scientific paradigm shift—one that can be applied to sociology just as easily as it can to biology. And this, in fact, has been happening for a very long time.

This was the case with the “modern synthesis,” better known as “neo-Darwinism,” an evolutionary theory that, when applied to social structures, has been used to justify the exploitation and competition characteristic of the ruthless capitalist system that has dominated—and continues to dominate—social relations at every level, from individuals to corporations and nations.

Lynn’s theories, which suggest that evolution is more about cooperation (even though she personally avoided using that term in a biological context) than competition, align perfectly with the paradigm shift that a portion of society is now advocating for (I was about to write a significant portion, but that might be overly optimistic).

This paradigm shift calls for a radical change in our relationships—with each other, with the other living beings we share the planet with, and even with the planet itself.

The Climate Summit currently taking place in Glasgow is a clear example of how necessary this shift is. It is also proof that the concept of “survival of the fittest” remains deeply ingrained in our society. That is precisely why so many Climate Summits have been necessary, and yet their results have been, at best, insignificant. And it’s not hard to see why—just before the Glasgow Summit, the G20 meeting took place, bringing together “the strongest.”

I believe Serrat—again, Serrat—captured this dynamic perfectly in another song, “Algo personal” (“Something Personal”):

“… The hitmen never miss an opportunity
To publicly declare their commitment
To fostering a dialogue of open relaxation,
Which allows them to find a preliminary framework
That guarantees minimal conditions
To create the mechanisms
That will drive a solid and capable starting point
From East to West and North to South,
Where they can establish the foundations of a friendship treaty,
That will help lay the groundwork
For a platform on which to build
A beautiful future of love and peace.”

But let’s get back to the screening in Zumaia.

One of the most special aspects of this event was that, for the first time, the film was shown in its original English version—with Euskara subtitles!

Collaboration and cooperation were the two key elements that made this possible. Collaboration between institutions such as the Zumaia City Council (Zumaiako Udala), the Basque Coast Geopark (Geoparkea Euskal Kostaldea), the Zumaia Women’s House (Zumaiako Emakumeon Etxea), and the Zumaia Naturalist Group (Zumaiako Natur Taldea); and cooperation between individuals, like the team of translators led by Inaxio Manterola, Alex Oliden, and Gontxalo Torre. Thanks to their work, Lynn’s theories and legacy could reach more people—and in their own language.

While in Serrat’s song, the “types” he refers to and I have “something personal” in a negative sense, the “types” I just mentioned in Zumaia and I also have “something personal,” but of the opposite nature. It is something personal rooted in admiration for their ability to collaborate, to work together in a completely selfless way on a project that aimed—and I hope succeeded—in offering new ways of thinking. And new ways of thinking, after all, are essential for the evolution of ideas.

And to top it all off—what better setting than the famous Flysch of Zumaia to talk about evolution? This extraordinary geological environment, now protected under the Geoparkea designation, preserves a 110-million-year record of our planet’s history—one that can be read like a book. Here, with the guidance of Geoparkea experts, it is even possible to see the K/Pg boundary (Cretaceous/Paleogene boundary), a thin “black line” that marks the transition between the Cretaceous (K) and Paleogene (Pg) periods, dated to around 65 million years ago. This line is characterized by an extraordinary concentration of iridium, a remnant of the Chicxulub asteroid impact in the Gulf of Mexico.

For those interested in the full program of activities organized to commemorate the tenth anniversary of Lynn Margulis’ passing (1938–2011), you can find it on our website, Science into Images.

Yesterday, Sunday, February 14, 2021, we aired the third installment of our radio segment on Maresmejant, a program on Mataró Ràdio, which you can tune into at 89.3 FM.

Here’s the link where you can listen to the full program (2 hours):
http://mataroaudiovisual.alacarta.cat/maresmejant

You can also access the audio of our segment directly (approximately 22 minutes) on our YouTube channel, Science into Images.
The link to this second program is: https://youtu.be/g4hguDCs_M4

Today’s main topic was the launch of the United Nations Decade on Ecosystem Restoration (2021-2030) and, in connection with it, the MITICAP and RESCAP Projects carried out by researchers from the Institut de Ciències del Mar (ICM-CSIC) in the coastal area of Cap de Creus.

The close collaboration between researchers and the fishing guilds of Cadaqués and Port de la Selva has yielded excellent results, demonstrating that ecosystem conservation is by no means incompatible with maintaining traditional activities—in this case, fishing. Furthermore, it has shown that citizen involvement in scientific research not only facilitates the work of researchers but also enhances project outcomes.

We also shared some information about the Hipatia Prize (organized by the Academia Europaea and the Barcelona City Council) and the upcoming Women’s Week 2021, both hosted by the Barcelona hub of the Academia Europaea.

At the end of this post, you’ll find links where you can access more information on the topics discussed.

We hope you find our contribution interesting!

The Disputatio of Barcelona and Marine “Cereal”

Today, Sunday, January 17, 2021, we aired the second installment of our radio segment on Maresmejant, a program on Mataró Ràdio, which you can tune into at 89.3 FM.

Here’s the link where you can listen to the full program (2 hours):
http://mataroaudiovisual.alacarta.cat/maresmejant

You can also access the audio of our segment directly (approximately 24 minutes) on our YouTube channel, Science into Images.
The link to this second program is: https://youtu.be/cBwxQFtdHZc

Due to the pandemic, we are recording the program using a remote application. However, today we had a technical issue—my computer decided to shut down (probably due to overheating) just as the segment began. Fortunately, thanks to the skill of the Mataró Ràdio technician assisting us today, we were able to finish the broadcast via phone. For this reason, you’ll notice a change in sound quality starting at minute 2:20.

Today’s topics were the upcoming Disputatio of Barcelona (scheduled for next Tuesday, January 19) and the recently announced discovery of a so-called marine “cereal”—which is, in reality, the seed of the seagrass Zostera marina.

At the end of this post, you’ll find links where you can access more information if you’re interested.

Last Sunday, December 6, we embarked on a new Science into Images adventure—a new kind of safari, similar to the ones we usually take into the microscopic world, but this time, venturing into an almost entirely unknown territory for us: the world of radio waves.

From now on, one Sunday each month, we will explore the possibilities of communicating science and sharing its wonders through the microphones of Maresmejant, a program on Mataró Ràdio, which you can tune into at 89.3 FM. If you can’t listen live, you can always catch up one or two days later in the A la carta section of the Mataró Audiovisual portal.

Here’s the link where you can listen to the full program (2 hours):

You can also access the audio of our segment directly (20 minutes) on our YouTube channel, Science into Images.
The link to this first program is: https://www.youtube.com/watch?v=LMXQTM_Oqjc

We are delighted with the warm welcome from the program’s veterans, who have provided us with all the support we need to develop this segment and given us complete freedom in selecting and discussing our topics.

For the premiere, we chose a rather complex and little-known subject: organoids. We hope that our explanations—brief and partial as they may be (since time on the radio is inevitably limited)—have sparked curiosity among listeners about these remarkable developments in biological research with direct applications in medicine.

In addition to this main topic, our first broadcast also covered other science-related activities in the form of a news-style commentary, aiming to keep listeners informed about scientific events and outreach initiatives.

We hope you find our contribution interesting!
