Thoughts about Science and COVID-19

I’ve written about science for many years, mostly space and astronomy topics. It’s actually quite satisfying to do this work. I get notices of people’s scientific accomplishments, and I get to tell their stories. It is, after all, people doing science. It just doesn’t do itself. The planets and stars and galaxies will continue to do their thing. Our observations of those objects and their activities will help us understand them. Same with any other science.

Science is a process of discovery. It doesn’t stop at one “aha!” moment. Science discovery continues from one moment to the next, as new data comes in. Data points are the core of science. Gather enough data and you have something to talk about, to make models of, to construct theories and rules about what you have observed. That’s the way science works.

So, for example, in the current pandemic crisis, what science can do is gather data points about rates of infection. That information is gold because it helps us do more to help prevent the spread of the disease and help those who have it. We can also learn how to avoid getting it based on data.

For this one, researchers need a LOT of information. They can use data from places where the infection rate is rising or falling. They need information about who is affected and how it was spread. Scientists can look at who survives and who doesn’t, and what measures were taken to help the survivors. Researchers also need data about populations and relative rates of infection over time. And, they can use this and other information to figure out how best to treat it, where to send much-needed medical equipment, and so on.

Oh, and they can work toward creating a usable vaccine. That seems pretty straightforward. And, that’s how it should work.

Science Denialism

There are people in the world who don’t like science. They fear it. Or they fear what it might tell them. Or they fear what it might say about their political “leadership”. So, they deny it. Or they threaten the scientists doing the work of understanding things.

In most cases, people deny facts that are clearly right in front of them. We are seeing a lot of that today, with the spread of the SARS-CoV-2 virus and the COVID-19 epidemic it is causing. In addition to the truly silly conspiracy theories about the sickness, there are people who are spinning data points out of context, or simply not collecting or reporting data at all.

There are likely political reasons behind the slow reporting of infections. However, there are also some practical reasons and those need to be overcome. One of the biggest issues is that there aren’t enough tests being made available in the U.S. to definitively test everyone who may have the virus.

Another obstacle: not everyone who has the virus shows symptoms. As in any other science, medical people have to have actual examples of the subject in front of them. In medicine, someone with symptoms gives them information. Someone without any symptoms isn’t going to present themselves. And, thus, medical researchers and doctors can’t even begin to consider if someone has the virus or not.

In addition, folks without symptoms have no way of knowing that they do have it. That also contributes to a lack of data. And, strong science requires strong data points. Science about this virus and its effects needs better reporting. That’s a fact. It will help people learn WHY social distancing is so important, why staying home and following cleanliness guidelines may help save their lives or the life of a loved one.

I hope that more data will be reported. As doctors and others get a handle on the many side effects of this virus, how the illness it causes presents itself, and other aspects of the epidemic, I want to see them get what they need to know. It’s the only way to understand this particular pandemic.


Just the Facts, Please

We all should hope that medical science gets what it needs. Our lives depend on it. Our societies can’t function without more information. Scientists can’t make headway on understanding this illness or the virus without information. Worldwide honest reporting of data is important. This isn’t the time for political posturing or national pride that might prevent accurate numbers from getting out. Just the facts: they are the heart of science.

Searching out New Life… or a Virus

Most of us can remember the opening lines of Star Trek: the Old Series,

“Space… the final frontier. These are the voyages of the starship Enterprise. Its five-year mission to explore strange new worlds, to seek out new life and new civilizations. To boldly go where no man has gone before.”

Probably a lot of us use it as a mantra as we wash our hands these days. Anything to help us avoid the strange new bit of life form called a virus that is making its way around the globe.

I must admit, I’ve been giving it some thought as I scrub up after a rare trip outside the house. I’ve also been flashing the Vulcan salute to others as I pass (not too close) by. It’s strange how one small infectious agent can change entire cultures. (And, how many Star Trek ideas are wrapped up in some cultures.)

So, in the spirit of the Enterprise and its many-year mission of exploration, though, I’ve been thinking about this virus a lot lately. Last week I posted about home-bound observing, which I hope some of you are able to do. Today, I want to talk about encountering new life forms (or bits of them).

The Virus Itself

First off, there’s debate about whether COVID-19 (which stands for “Coronavirus Disease 2019”, the disease we’re all facing) actually IS caused by a life form. The actual virus doing the damage is called SARS-CoV-2, which is short for “severe acute respiratory syndrome coronavirus 2”.

Strictly speaking, a virus is a form of DNA or RNA. And, the material that is behind the COVID-19 epidemic is a virus. But, like any other virus, it can’t exactly replicate itself the way life does. For a virus to be a success at what it does, it has to invade a living being. It needs a host.

Once it finds one, it gets inside a cell of a being’s body and takes over the mechanical bits of cells. Then, they use the cellular machinery to make copies of themselves. In other words, they hijack cells in order to find a way to replicate. When they find a cellular Garden of Eden, viruses replicate with a vengeance. As we’re finding out with the COVID-19 outbreak; the SARS-CoV-2 virus that causes it is a hardy and opportunistic traveler.

In the sense that it can’t reproduce itself without sponging off another living being, the virus isn’t strictly alive. But, it IS part of the stew of life on this planet. It might NOT be alive on its own, but it sure can wrack up damage inside of things that are alive. The trick to understanding its spread is this: A virus can’t do anything until a host ingests it, picks it up, or somehow gets it inside the body.

So, we can dance on the head of a pin all day and debate about whether the SARS-CoV-2 virus is alive. That’s not the point. The point is, it’s like a hitchhiker or a bad political idea. It hops aboard and goes along for the ride, replicating as it goes. And, the more hosts it gets, the more it replicates. Ad nauseum (perhaps literally). And, it’s not benign. It makes people sick. Some of them get very sick. And some die.

Don’t Cry for Me, Quarantina

The trick to defeating this quiet, deadly little piece of DNA/RNA is to deny it the ride. Hence, the quarantine. And, all the stay-at-home orders percolating around the world. Some countries (like China) figured this out pretty quickly and shut down everything as soon as they could. Other countries… (ahem)… did not. And, thus, we see the spread of the virus by people who have traveled freely, went on spring break, and in some places, continue to have personal contact with people who are infected, and so on.

Some folks figure it’s okay if they get sick—they assume they can handle it. That’s fine for them. However, the illness the virus causes takes a while to manifest itself. During the time it’s busily replicating inside a person’s body, the hosts are out there. They’re busily helping the virus infect others who may NOT be able to handle it.

That’s the basic gist of how the virus travels around. It’s an opportunistic freeloader just waiting for someone to give it a ride. If people stop taking it around to parties, stores, and so on, then the virus can’t keep doing what it’s doing: making people sick, and some of them die.

And, that’s why we are urged to stay inside, avoid other people, do social distancing. In effect, we ALL need to inhabit the land of Quarantina in an effort to keep the virus from claim-jumping from one victim to the next. The fact that many of us are now working from home, and avoiding crowd situations will help the effort. That’s really all there is to it.

So, we may be asked (urged, ordered, pleaded, begged with) to stay in, it’s for a good cause. As our state governor put it yesterday, it’s should be a labor of love to care for others enough to stay home and not spread the virus to anyone else. This is true whether we have it, or we simply pick it up from a dirty door handle (or some other form of contact) and help the virus get a ride somewhere else.

New Worlds and New Life

There are, as we know, many other worlds out there beyond our own. And, on at least some of them, there is life. There might even be viruses. One thing that used to amuse me about Star Trek (in all its forms) was the very idea of simply transporting to other worlds’ surfaces. Crew members didn’t always seem overly worried about potentially lethal viruses or bacteria. They just beamed down and did their thing.

Of course, they had red shirts to send down first. But, they also had these biological scans they could do from orbit. Supposedly that would give the crew and away team members some measure of reassurance that they were transporting into a safe environment. So, even in Star Trek, there were forms of distancing, especially if the environment turned out to be less than hospitable. They had to figure out how to visit wearing suits or some other protection.

As astronomers search out new worlds, the questions of the types of life they support will grow. Right now, nobody has seen evidence for intelligent life. But, that’s more a function of where we’ve been able to search and find worlds. Many are not considered as habitable as others. It’s like searching for a needle in a haystack, and we’ve got a HUGE haystack to explore.

But, let’s suppose that we do find a planet somewhere nearby that might have life on it. It could be inhabited by bacteria. And, anyplace with the building blocks of life in terms of RNA and DNA, could also support viruses. And, our future Star Trekkers who are out there exploring strange new worlds are going to have to do exactly what we’re doing now on planet Earth: stay safe, stay clean, and not allowing viruses to hitch rides. We all know where those rides end up.
