Appreciating van Leeuwenhoek: The Cloth Merchant Who Discovered Microbes

Appreciating van Leeuwenhoek: The Cloth Merchant Who Discovered Microbes

Imagine trying to cope with a pandemic like COVID-19 in a world where microscopic life was unknown. Prior to the 17th century, people were limited by what they could see with their own two eyes. But then a Dutch cloth merchant changed everything.

His name was Antonie van Leeuwenhoek, and he lived from 1632 to 1723. Although untrained in science, Leeuwenhoek became the greatest lens-maker of his day, discovered microscopic life forms and is known today as the “father of microbiology.”

Visualizing ‘animalcules’ with a ‘small see-er’

Leeuwenhoek didn’t set out to identify microbes. Instead, he was trying to assess the quality of thread. He developed a method for making lenses by heating thin filaments of glass to make tiny spheres. His lenses were of such high quality he saw things no one else could.

This enabled him to train his microscope – literally, “small see-er” – on a new and largely unexpected realm: objects, including organisms, far too small to be seen by the naked eye. He was the first to visualize red blood cells, blood flow in capillaries and sperm.

Leeuwenhoek was also the first human being to see a bacterium – and the importance of this discovery for microbiology and medicine can hardly be overstated. Yet he was reluctant to publish his findings, due to his lack of formal education. Eventually, friends prevailed upon him to do so.

He wrote, “Whenever I found out anything remarkable, I thought it my duty to put down my discovery on paper, so that all ingenious people might be informed thereof.” He was guided by his curiosity and joy in discovery, asserting “I’ve taken no notice of those who have said why take so much trouble and what good is it?”

When he reported visualizing “animalcules” (tiny animals) swimming in a drop of pond water, members of the scientific community questioned his reliability. After his findings were corroborated by reliable religious and scientific authorities, they were published, and in 1680 he was invited to join the Royal Society in London, then the world’s premier scientific body.

Leeuwenhoek was not the world’s only microscopist. In England, his contemporary Robert Hooke coined the term “cell” to describe the basic unit of life and published his “Micrographia,” featuring incredibly detailed images of insects and the like, which became the first scientific best-seller. Hooke, however, did not identify bacteria.

Despite Leuwenhoek’s prowess as a lens-maker, even he could not see viruses. They are about 1/100th the size of bacteria, much too small to be visualized by light microscopes, which because of the physics of light can magnify only thousands of times. Viruses weren’t visualized until 1931 with the invention of electron microscopes, which could magnify by the millions.

A vast, previously unseen world

Leeuwenhoek and his successors opened up, by far, the largest realm of life. For example, all the bacteria on Earth outweigh humans by more than 1,100 times and outnumber us by an unimaginable margin. There is fossil evidence that bacteria were among the first life forms on Earth, dating back over 3 billion years, and today it is thought the planet houses about 5 nonillion (1 followed by 30 zeroes) bacteria.

Some species of bacteria cause diseases, such as cholera, syphilis and strep throat; while others, known as extremophiles, can survive at temperatures beyond the boiling and freezing points of water, from the upper reaches of the atmosphere to the deepest points of the oceans. Also, the number of harmless bacterial cells on and in our bodies likely outnumber the human ones.

Viruses, which include the coronavirus SARS-CoV-2 that causes COVID-19, outnumber bacteria by a factor of 100, meaning there are more of them on Earth than stars in the universe. They, too, are found everywhere, from the upper atmosphere to the ocean depths.

Strangely, viruses probably do not qualify as living organisms. They can replicate only by infecting other organisms’ cells, where they hijack cellular systems to make copies of themselves, sometimes causing the death of the infected cell.

It is important to remember that microbes such as bacteria and viruses do far more than cause disease, and many are vital to life. For example, bacteria synthesize vitamin B12, without which most living organisms would not be able to make DNA.

Likewise, viruses cause diseases such as the common cold, influenza and COVID-19, but they also play a vital role in transferring genes between species, which helps to increase genetic diversity and propel evolution. Today researchers use viruses to treat diseases such as cancer.

Scientists’ understanding of microbes has progressed a long way since Leeuwenhoek, including the development of antibiotics against bacteria and vaccines against viruses including SARS-CoV-2.

But it was Leeuwenhoek who first opened people’s eyes to life’s vast microscopic realm, a discovery that continues to transform the world.

Slog AM: Welcome to the United States of Texas, Bob Ferguson Is Our Next Governor, Tanya Woo Is History

Seattle's only news roundup. by Charles Mudede

We wake up today with this certainty: None of it mattered. The secret documents, the sky-high covid deaths, January 6, racist statement after racist statement, the economic crash, the sexual assault allegations, the pussy grabbing, Moscow,  Roe v. Wade, the conviction, and what have you. All of it amounted to a hill of beans. And there will certainly be more outrages in years to come; and once again, they still will not matter one dot. If we, on the left, come to this understanding, we can move on by simply asking: What, then, does matter? What truly counts in American politics? What is its actual ground? This kind of clear thinking might prove to be invaluable.

We also have to accept the fact that California no longer represents the future of America. In the past it did, but not anymore. The future is now found in Texas. Elon Musk knew this. He relocated himself, Space X, and X to what has become our whole country: the Lone Star State.

Kamala Harris only won deep blue states: And Trump is going back to the White House because millions of people decided to "sit this one out." And the Senate returns to the GOP. As for the House, its final composition is yet to be known. Now, how are we to read all of this, and, particularly, the outcome of the presidential race? Well, Trump's first term in office is something like the first book in Octavia Butler's Parable series, Parable of the Sower, which was published in 1993 and features a Trump-like president who basically strips America of its economic assets. The second term will be like the second book, Parable of the Talents, which was published in 1998 and features an out-and-out Christofacist president who promises to “Make America Great Again.” Butler never completed the third book in the series.   

"Welcome to how our only world ends. It will be like this every summer: getting worse, and worse, and worse until there’s nothing worse left."https://t.co/vs5HAmUloY

Florida and South Dakota gave abortion access the middle finger. But Arizona, Colorado, New York, Maryland, Missouri, Montana, and Nevada protected reproductive rights. However, with the Senate, and possibly the House, under GOP control, the whole states’ rights business might turn out to be worth no more than the salt you put in greens.

The Stranger Election Control Board had a good night. Alexis Mercedes Rinck is going to beat incumbent Tanya Woo for Seattle City Council Position 8. The same goes with Democratic Socialist Shaun Scott. He will certainly beat Andrea Suarez in the race to represent Washington’s 43rd Legislative District. And the man who did not catch the Green River Killer isn't going to Olympia. Bob Ferguson handily defeated Dave Reichert for the governor seat. Sen. Maria Cantwell gave her opponent nothing but the boot. And, altogether, it seems Washington became bluer, saner, a little world, a precious stone, set in the reddest of seas.   

Now that the whole country is basically Texas, Seattle might consider not staying in bed with conservative council members. Now is the time to get up and go hard to the left.   

Voters showed Washington State Ferries (WSF) some love this time: The Prohibit Carbon Tax Credit Trading initiative  went down in flames. This means WSF will get electric ships and some badly-needed government cheese. However, the Ensure Access to Natural Gas measure , which wants to decelerate Puget Sound Energy’s departure from carbon liberation and protec the buyers and sellers of natural gas statewide, left the gate in the lead: 51% to 48%.

Joe Kent is facing a second round of wound licking. His opponent in Washington's 3rd Congressional District race, Congresswoman Marie Gluesenkamp Perez is, at this point, ahead by 4 points.

The sun will be out today. That's something.

A termite mound that's been around for something like 34,000 years was recently discovered in South Africa. Of course, termites haven't called this mound home for thousands of years. And this is a shame, because termites are really delicious. You catch them during the rainy season; this is when termites take to the sky with lots of fat in their bodies (they are trying to start a new colony—the circle life, that sort of thing). A little cooking oil and a few minutes on the burner turns these brown critters into a tasty snack.

Let us end with this scene from Downtown 81. Ronald Reagan is president. Hip-hop is emerging. And Jean-Michel Basquiat is getting his groove on in the ruins. What I want to point out is the way he moves. So smooth. So cold. So internal. This is being with others to be by yourself. This is exactly how I feel today. Dancing to the aftermath.
